Billet Rocker Covers For LS1/LS2

[IH8WRX]

Hi guys

Simply would like to know if Harrop have any interest in making billet rocker covers for the LS1/LS2? I know you people made them for the HRT427 Monaro and just wondered if you would make them upon customer request OR maybe look at a small scall production of these?

If so what would prices etc be? Feel free to PM me these if you like. Berni knows who I am and I'm enquiring on these for my car (which Berni has seen my engine bay) and also a customers car too.

Kind regards
Rick

Hi Rick ...
We have done a couple of varities of billet covers ... but they are too expensive to do as a "stock" item.
We have just completed some for a Holden show car that will be displayed at the Sydney motor show, and they came in at about $3,500!

If you have an idea of the "look" you want we can give you a quote, but I expect that they will be >$2000 for a 1-off set. :eek:

You can probably get them from the USA for a more acceptable fee.

[IH8WRX]

Thanks Ken

Ok do you have any other cost effective solutions, apart from sourcing these from the U.S.A.? I'm still not 100% happy with what they have on the market either and personally think a lot better looking items could be made with some proper thought. Reason being is I have finally come up with a kit to relocate the coils successfully and therefore clean up the rocker cover area. Simply looking for something better than the stock OEM items, that have both functionability, practicallity and looks. Wouldn't need to be made from billet, but something that is similar to the look of the prototype HRT427.

Is it possible to see any pictures of the current set you have just made or strictly "top secret" til Darling Harbour?

[v8 ute]

I had some made for mine out of billet aluminium, I could get some for you for under $1k a pair.

The ones for the show are definately not viewable yet ... but I think they will be worth the wait.
If they get a positive "review", we will probably do them as a casting which gets polished to look like billet units. they would probably be ~$750 a pair.

The reason the billets units we make are more expensive that the alternatives is that ...
1 - We make them from high-tensile heat-treated aluminium which polishes the best.
2 - We make them to suit the high-lift & high-ratio rockers, which requires the "cavity" to be undercut and consequently they need to be made on 4- or 5-axis machines.
3 - We spend a LOT of time ensuring there is minimal machining marks and as they are lightweight (thin wall sections) and this can take some effort.
4 - Our designs typically are "soft" with lots of shape, which also increase machining time. If we were to make units similar in design to the "hard/harsh" shapes that come out of the USA etc we could be price competitive, but that is not the style of product we want to be associated with.

I realise that the justification above can be perceived as "spin", but it may help you understand why I was hesitant to respond with a solution.
:D

[IH8WRX]

Thanks Ken and tell Ron he should be paying you more :D

That was a great response and understand it perfectly. It would be good if Harrop would proceed with the "cast" style that's for sure. I know two sets that would be sold already, possibly 5 more too.

Ken is it possible for me to ring you Monday to discuss something with you over this mater professionally wise? If so what's the best number to get you on? I just would like to talk to you about my coil relocation idea and see if it can be incorporated into your design so we both get something out of it.

Cheers
Rick

[Ken]

... pay me more !!?? :confused:
I have one of the best jobs ... I get to do what I enjoy while being surrounded by a bunch of very skilled guys who make me proud to be involved in the stuff we do. I feel quilty now ... as Ron has always been quite generous.
Sometimes the rewards are not always $$ ... the best rewards are the little things ... like a client who sent us a little "Thank You" card in which he noted how much he was enjoying our supercharger kit. :cool:
Kinda makes up for the "lost" weekends in front of the CAD screen or dyno (my wife may not agree!).

I would welcome any input to the rocker-cover concept. Please feel free to call me on Monday ... 03.9474-0900 is usually the easiest. If I'm in the dyno cell 'making noise', the girls will take a message & I will respond ASAP (which sometimes can be too long :( ).

It is almost certain we will do a rocker cover of some variety, as we will be releasing our new LS1 cylinder heads within a few months, so it is a natural progression. We have done a remote coil-pack mount for the previous covers but it is not very elegant, so if you have a solution which we can work with it would be one less hurdle.

[Chris5.7ltr]

Sorry to hijack and butt in but I was thinking about this a while ago...

Knowing a set of billet rocker covers are pricey to make wouldent it be better to either make some out of alloy sheet metal or even do a cast of one (like C.O.M.E racing do with there allow head) and mass perduce them out of alloy that way?

Absolutely ... except then they wont be billet covers, they will be fabricated or cast. ;)
Our "production" units will probably be cast ... or perhaps carbon fibre.

I'll be in touch Monday Ken. I just have to make sure there is no power loss from making the spark plug leads longer for the relocation design I have as that is my only issue.

Just joking about the pay comment to. It's great to see premium sponsors so on the ball and willing to do what they can. There is a carshow coming up at the end of October in Brisbane and I have some very tough LS1's I want to put on display that are forum members and thought I really should be getting this done ASAP as one will have your manifold on by then and the vehicle already looks sensational, as to another one is well known throughout Australia plus my own SS too.

Thanks once again Ken for the informative replies.

[IH8WRX]

Ohhh forgot to add. It doesn't worry me personally what they are made from, wether it be billet or cast as mine will be painted the same colour as the block, manifold and other parts etc, however one vehicle that I'm looking at putting a set on will need to be highly polished and so will the other vehicle too.

I'm sure Harrop will come up wih something that will be perfection +++++


Just in case you haven't seen my engine Ken

Yes I understand that, but my point is I'm sure theres a market for cast and sheet metal rocker covers (cast ones could be chromed) for guys like me who are just after the old school look in there engine bay.
Thats all.:)

Chris, I'd be concerned about having chrome internally in my engine. I know it isn't exactly in the heart of the engine, but chrome rocker covers could be a problem as it would be near impossible I would have thought to electroplate only the outside and not the inside too.

If the feedback is positive, we will probably do a cast version.

There has to be a way of doing it, they can do it with the rocker covers for older engines (Holden V8s etc)

Now thats what Im after! :cool:

I second that :D

[COUPE]

I can never understand why GM makes these V8 engines so ugly by placing the coil packs over the rocker covers.

Part of the romance of owning a V8 is to pop the bonnet see that magnificent V staring at you with some mean looking rocker covers. Not some wired up Frankenstein creation they look like now.

Even if it cost them a few $ more per car, they should of redesigned it.
Who do they think buy V8's? People who don’t care what's under the bonnet or what it looks like? Simple things like that would improve the aesthetics so much.


Would love to be able to get this look with the coil packs relocated this way, and these rocker covers.

[Ken]

For anyone that is interested, check out the rocker covers on the Holden Efigy show car. We are considering doing a production run of these, and would value some feedback.
(I hope someone has some photos to post ;) )

[Ron]

I went there yesterday Ken and they kept the bonnet down :mad: :mad: .

I made some enquiries as to why and nobody could tell me :rolleyes:

[exwrx]

Ken, if you want some feedback on the rocker covers - build them and they will come ! (depending on pricing of course)

BTW, that is one of youre blowers as well I assume?

[cobra1]

Ken,

How many RC orders do you need to make the excercise viable ??

Wouldn't mind one of those blowers with the inline TB ?? as it would line up better with the CAI I have in the Cobra.

Any chance of this or do I have to use the other guys.???

Phil :)

Yep ... we will build them. The response has been great.
The blower is one of ours, although the Holden arranged for the polishing.
Seriously good engine.

We will be doing the rocker covers ... As EXWRX sez, if we make them they will be viable.

We have the straight throttle body adaptors in stock. It is made to suit the 90mm LS2 electronic TB, but we are also considering doing a billet cable-pull 90mm version for the LS1 PCM.
:D

[warrick]

put me down for a set of the rocker covers! VERY VERY NICE!! let us know when available.
cheers
warrick

[TOYLS1]

i would be in for a set of cover too ken,

cheers
christian

[Ken]

We have started the re-design & tooling for casting these. They will be available in the new year (sorry ... no shiny metal Christmas presents).

They will be the same style/shape etc, but we need to re-design them to suit all variants of LS1/2/7/76 and ensure they will be suitable for emmision testing issues.

We will probably not polish them ... but demand will determine that.

:cool:

[VXSS]

We will probably not polish them ... but demand will determine that.

:cool:

I'll start the demand then :lol:

Polished pls

[RhysB]

I'll start the demand then :lol:

Polished pls

1 Set for me too thanks :)

[Ken]

:confused: This may seem like an odd request, but I need help.:confused:

We are reasonably confident we know how much these will cost to make (including ammortising the tooling) but I fear that the price is more than the market will accept. I have made some enquiries regarding the price of small-block (& other) aftermarket covers, and are suprised at the price variation & range between options/models/manufacturers. There is some VERY cheap small-block stuff out there ... costing less than the raw material cost. :eek:

Please let us know what you would consider "fair & reasonable" retail pricing for polished cast units which look like the Efigy billet ones above.
I realise that this is not considered normal or "good business practice", but we are passionate about making them but it must be viable.
;)

[james2]

Personaly i would have no idea of cost either , however if the product is as per your usual high standard then they should still sell .I would love to have a set on my car so would buy at some point ,could be taken of when selling and used on next car . If they were able to fit LS2(?) then so much the better.( Upon reflection) $400 per set would see my order Post Haste to your door .Regards james

[TOYLS1]

i am in ken i think about 500 is good if there are your high standard

[BlueSS]

I've been checking out ones available in the US, most of them work out arround the $450-500 mark by the time you convert to AU and add freight etc..

[Ken]

OK ...

We have pressed the "GO" button on the rocker cover project.
We are doing a slight re-design (internal) to ensure that they will suit the high-lift and/or high-ratio rockers, and also re-designing the retention method to ensure no potential for oil-leaks.

We will be offering them in cast, painted & polished finish.

:D

[james2]

Now that the "GO" button is on :D what time frame are we looking at for the covers to be available? thanks james

[Ken]

Hmmmm ...
These are the sort of posts that get me in trouble!:bash:
Unfortunately, our internal projects like this get second priority as its the other work that pays the bills. Consequently, I would not expect to have them complete before mid-Feb ... but anything is possible. It really does depend how much 'other' work we need to do concurrently.

Now I just gotta hope that we sell enough of them to pay for the tooling ... :eek:

[RIDE:42]

Are you makeing the set up for the coil pac relocation as well?

[Ken]

Are you makeing the set up for the coil pac relocation as well?
That's the intention, but on initial investigation it appears that we will have to have several versions as there are several variants of under-hood layouts.
:rolleyes:

[NickS]

Ken,

Sorry if this is a stupid question, but are modifications (to the stock engine layout) necessary, or will they just bolt on.

cheers, Nick

[Ken]

Ken,

They will be a direct bolt-on replacement for the standard covers. No engine modifications will be necessary, except for coil-pack relocation.

Can u give a little more info on this????

John

[Ken]

Can u give a little more info on this???? John

Yep ... When we have it figured out :D ;)

after reading through all of that i must say.....WOOHOO.....and if its around th eprice people have been saying they would pay, thats 3 thrown over this way thanks.....cant wait!!

[TTVYSS]

Yep definately interested!!!!!!!!!

[SSute]

Great I'd love a set for my LS2 Maloo. Only thing is, to see them properly you would want to take off the engine cover which hides ugly stuff. ohwell have to get a polished supercharger too :D

[Ken]

... have to get a polished supercharger too :D
We can probably help with that
:D

[Wayne@GM Motorsport]

Any news on these ?

[Ken]

The design is progressing well (again). We had to have a little re-think as we are making the to suit all the variants we can find (LS1, LS2, L76) and each have a slightly different internal breather and/or PCV configuration. It is our intention to produce 1 set of covers for all the variants so that a vehicle/engine upgrade does not mean having to purchase another set of covers.
We are making good progress ... tooling should be starting shortly.
:goodtime:

[Trip]

Is it too soon to start putting in orders? Im really keen

[Ken]

I would prefer you can see what you are getting before you place an order ... but we are pretty happy with the design.

We have "signed off" on the final design.:dance:
Unfortunately, it is a project that has to happen in the background as the various race teams orders are fulfilled prior to season-start. It has been a busy time ...

I am not willing to give a release date ... but it will be soon as we have invested a lot so far and we are as keen as you to see the result delivered.

If we could just get rid of those pesky customers who keep wanting us to do work for them, we could concentrate on making the cool stuff !! :lol:

[shiro_tengu]

Hi all,

wow this is actually my first post. So hi!!
I am yet to meet an owner of an ls1 who would not like an attractive motor. I had the privilage of looking at the Effigy at the Perth motor show. All I can say is its wonderful and the engine is a dream. I would love to loose that mutant ninja turtle shell and have something impressive under the hood.
Ken, count me in!! My baby needs some!!

dont lie, you make it sound like theres actually stuff you make and its not cool :bravo:

id be keen on a set, god knows its an ugly turtle under there...

sorry if i missed it, but can you pm any idea you have on cost on relocating stuff and fitting in the new rocker covers.

thanks in advance.

adrian.

looking very good ken! :D are u guys going to have a coil relocation kit or something like that?

[Ken]

We intend to ... but we have not fully completed a design we are totally happy with yet.
More to come ...

Looking very good, I'm quite interested in fitting some of these up.
Will they clear FAST/Wilson fuel rails & manifold though?

We have tried to make them as compatable as possible, with most optional items we could find.
We are reasonably confident they will fit with the Fast, and with most high-ratio rockers etc.

Coil pack relocation is proving a little tricky, but do-able.
They will be available polished with red logo.

[ls2maloo]

Just wondering how the engine covers are coming along,any release dates yet.Thanks

[Ken]

First castings were made this week ... Look good. The jigs and fixtures for NC'ing them are nearly complete.

We have been working on some polishing options and are very close to finalising the coil pack relocation modules (there are a few variants for different model vehicles).



On the final lap now ...

:teach:

[TOYLS1]

sounds good ken, can't wait

[james2]

Will it be a possible Fathers Day present??????????:)

[GTO_]

Any updates on these covers? How are they coming along? Any pics?

[TOYLS1]

any news ken? we near seeing a finshed set

[Ken]

We have now finished the first castings and are completing the manufacture of the installation kits. We are very pleased with the results, and should have some photos of the LS2 installation ready within a week or two.

There are more varieties than we first anticipated due to the variants in vehicle models (about 6 different combinations of vehicles/engines).

An early rendering can be found here (http://gallery.harrop.com.au/main.php?g2_itemId=433)

[aperfectcircle]

Thats great.:yup:


Sign me up for a set:bounce:

[Ken]

Some pre-production photos can be seen in the Harrop gallery here... (http://gallery.harrop.com.au/main.php?g2_itemId=89)

As clearly visible, these are literally the first off-tool-samples and not production quality ... but an indication of the style.
We will be offering them "raw" or "polished", and as covers only, or complete installation kits with looms and leads.

First production run is scheduled for later this month ... but I will post an "installed" image before then.

:yup:

[Ken]

Some polished images have been added to the gallery.
Getting close now!

[aperfectcircle]

Well the fuel rail looks good as well

:bravo:

[VT-099]

These covers are going to be a must have item :yup:

Where abouts are the coil packs going to relocate to? I would imagine heat is a concern?

Any idea of indicative pricing?

[Ken]

Where abouts are the coil packs going to relocate to? I would imagine heat is a concern?

The covers were not too hard (although making them suit 'all' varieties has been a challenge), but the coil relocation packs have been really hard to get right. Unfortunately, I am guessing they will be copied/plagerised/imitated & de-engineered by the industry's parasites within weeks of release ... as happens with a lot of our products. :vpo:
The relocation position depends on the model vehicle ... there are a few variants. We will release pictures within a week or two.


Any idea of indicative pricing?

Yep ... a really good idea!
But we will not be releasing the final price until we have some stock to sell as I am confident the price will be very attractive. :bravo:

He is in the final stages of tuning the TSK supercharger and hot rodding the sleigh so the rocker covers should be a good finishing touch:)

The plan is to have them ready "very shortly".
We will advise when we are only weeks away so orders for the first batch can be placed.
Thanks for being "pushy" as it makes the work all worth while.
Regards,
Damian.

Any pic's of the relocated coil packs installed?

I second that, I'm keen to see where you've relocated them too.

VT-099,
The coils have now been registered in our witness relocation program so currently their location is confidential.:rofl:

Anyway, we are currently fitting them at the moment so should hopefully have some pics on the web site tomorrow.
The kit certainly changes the engine appearance.:yup:
Regards,
Damian.

Hi All,

I've relocated the coils on My LS1 powered Cobra. I machined up some brackets and the coils are now inside the car in the ends of the foot boxes. The ends of the coils poke out through 4 holes on each side and the leads run straight to the plugs.

I'm getting some custom length leads made at the moment and hope to have some pics of the leads in place soon.

In the mean time here's what they look like with the stock leads plugged in. Some aren't long enough hence the need for custom leads.

As for the wiring to the coil packs, I stripped back the loom and re routed the coil pack wiring inside the vehicle. I also remade the coil pacl looms to get rid of the excess wire as the setup is much more compact now.

Here's the coils mounted in the end of the foot box.

Here's my coil brackets

And a sneak peek at what I'm putting together for a bit more get up and go.

Nice :lol:

[exwrx]

Tell 'em the price son :jester:

[Sales@Harrop]

Installed images and pricing are currently being uploaded onto our web site in the engine components section. :smilesandbanana:

We expect to have our intial batch ready for shipment 4-6 weeks.
This first batch will be on first come, first served basis.
Now guys, get them orders a happening!!!:party:

Good stuff.

I had some concerns, but they should fit fast all of this.

Actually the extensions might need to be a bit longer to get past the turbo . infact it might get a little warm if they run over the dump pipe :1peek:

Polished would look nice in there.

Hey, whats with each exhaust pipe having a bung port on the manifold ?

Doing some serious emissions testing eh?

[GETUTED]

Damn they look good. I little more expensive than i was expecting but quality = $. :D

I don't reckon that the emmission test equipment would like the readings this engine produces! :eyes:

When we are doing some serious calibration on the dyno, we run 10 lambda sensors ... 1 on each header pipe and 1 in each collector. The data from these & the other array of sensors are collected by the data aquisition unit that is integral to our dyno. This allows us to interogate the data for fuel charge and temperature per cylinder so that we can have confidence in the distribution through the supercharger and intercoolers. The placement of the supercharger on the manifold can have a significant effect to the consistency of the air dispersion, as can the design of the intercooler.

We consider this degree of data-mining paramount to the integrity of product development.

is this on your car Ken?

[Ken]

Yep ... temporarily.
The units shown are pre-production and have a few minor surface blemishes etc.

[v-comp]

Very nice work guys, (I know how much is involved)

Good package at a fair price--well done :)

[aperfectcircle]

Any feedback on these items yet

[cobra1]

Sorry Ken,Couldnt wait ....bought some carbon fibre jobbies from the US.

Don't be sorry ... None of us are happy with the delay. Glad to hear you found a suitable aolution.

We now have 50 sets cast and will be machining them over the next few days. Polished units will take a little longer, and some of the relocation kit components are still coming (leads etc).

Got any pics

[GETUTED]

isn't this HARROP's forum..............for harrop products.......:confused:

[aperfectcircle]

Dont worry, I only want to see a pic of it.

I fully intend to get the Harrop set-up.

[aperfectcircle]

I see use have dropped the "LS_Aluminium_Rocker_Covers" off your web site did this fall though?

[Ken]

Not at all. Just a re-shuffle of the web-site.

We have some stock of non-polished units, but very few coil-relocation kits as the loom supplier has not managed to keep up with demand. We are working 24 hours a day at present ... and still not keeping up.

Need some more good CNC operators and some more casting-experienced people!;)
