N/a ve l98 - 347 rwkw

[APS Luis]

Had some very pleasing results late last week with a VE SSV L98 M6 - cam, springs exhaust only .

The customer wanted an OTR ,on this occasion we fitted the Ramjet , next we'll be trying out the VCM OTR it looks awesome.

A bit of modifying was required as the ramjets seem to be designed for MAF operation ( as always with cams , we did a MAFLESS tune )

Right from the very first pull this thing sounded tough and after some tweaking, this is what we came up with.

Really tough idle , but totally driveable - now he reckons the blower can wait a little longer !

Nice result.
Should keep the customer happy for awhile

[AQICLS3]

Nice result......What size cam?:goodjob:

[Vulture]

Great effort. Must be a pretty sizable cam though?

[indyeve]

what system did you use mate?:goodjob:

[KPWISHN]

A mans cam used obviously. Is that wheel spin at the top of the graph? or what's going on there?

[vscorsa]

Mint, any video's of idle and driving?

[Roonstain]

Any reason the Motec correction factor was used?

[APS Luis]

Any reason the Motec correction factor was used?

Hey KPWISHN:

Man's cam for sure - but not as savage as you'd imagine.
Not sure what was going on there ( I doubt very much it was wheelspin ) , but it did it on almost every run - look carefully you'll notice it's just after the peak point in the torque graph , I tried correcting it via spark but didn't really respond...

indyeve,

System ? I don't understand your question:)

Roonstain ,

I'm not 100% sure of how the motec correction works , so I wont elaborate ( i think I may have read something about it on another thread ) - regardless, I'll give Andrew or Todd from Mainline a call tomorrow and get them to explain , it's something that gets done automatically ( we don't touch ).

vscorsa,

Will get an idle vid 4 ya when it comes back for it's 1000km checkup.

Come on, no secrets on here :) what size???:1peek:

And by system I presume he means what type of exhaust system did you fit??


Good result none the less, Im looking forward to my cam , springs, otr and tune very soon :D

[TROY]

seems like a lot of torque

[APS Luis]

Ok - re: "Motec correction"

Straight off the Mainline dyno site :


"Our Hard-Wired Premium Quality Automatic Weather Station Module measures and displays all atmospheric conditions required for "automatic" power correction calculations, ensuring repeatable test results throughout changing weather conditions. Relative Humidity, Barometric Pressure, and Ambient Temperature are measured, displayed and used to automatically correct torque and power figures. Additional information such as Air Density and Atmospheric Correction Factor are also calculated and displayed. Atmospheric conditions are also saved with test data and included on all printouts for easy reference. Seven Standards – SAE J607, SAE J1349, DIN etc are available for the operator to choose from. The Correction Factor applied is visible on-screen and included on printouts. The maximum correction that can be applied is capped at the allowable maximum dictated by the correction standard being used to avoid producing unrealistic figures.

Our Weather Station directly inputs atmospheric readings into our software. This serves two important roles. Being fully automated, it is a variable the operator doesn’t have to worry about as the software continually updates the Atmospheric Correction at least once per second. The other advantage is that it takes away the capacity for operator inaccuracies (as can affect results on other dyno systems where data is entered manually or air temperature in the manifold etc is used to calculate the Correction Factor)"


IBEAST2NV,

Exhaust was a full 3" Di filippo system , cam specs are " APS Grind " - LOL ! , nah , really , still waiting for the boys to get me the details, but will post soon.

p.s. it seems like a lot of torque because it is !

[indyeve]

what system did you use mate?:goodjob:

sorry mate exhaust system

[ebbett21]

sorry mate exhaust system

on dyno sheet say diffillipo:1peek:

[indyeve]

ooops!!!!!:1peek:

[ebbett21]

Now a question how much different does he diffillipo exhaust note change with a cam upgrade as to stock cam anyone?

[JaMeS_2007]

i had heads and cam added to my DF system the note got alot deaper and makes alot more noise.

[Thorpey]

:goodjob: by the way APS... Just want to air my gripe as we are talkin 'custom' grind spec cams. I have had a 'cuatom' cam done in my car and the place i had it done wont even tell me, the damn owner of it what the spec is??? i thought it was damn strange not to mention anoying but to my surprise my m8 just had his 'custom' cam done in his r8 at another shop altogether and guess what?? They won't tell him either :vpo: Like...WTF???

[bourny]

It does seem like alot of torque. My blown 5.7 makes a little more than that. Pretty good results :) good work.

So, why not say to the shop "If you won't tell me what's going into my car, I won't buy it."

That should sort them out...

[Rub]

HOLY....

Nice work lads...

Would be good to see what it does with a set of heads (even though we know how the intake flows on the L92 heads).

now back in your box..

and i'm sure that customers whom purchase a "custom cam" are told the specs of the cam, but are asked not to tell..

In your instance, who knows wtf is going on..

[ADAM 26]

just take the cam out and get it measured, then you will know the exact cam specs. i personally wouldnt buy a cam that the specs were un known.

[1BEAST2NV]

next we'll be trying out the VCM OTR it looks awesome.


so have you done any VCM ones yet since this???

[AGIT8D]

Which shops did you and your mate go to?

[Trewman]

If I got great figures like this customer I wouldnt give a shit what specs the cam were! It was prob a case of a little bit of grind here a little bit there and it turned out awesome :D

[APS Luis]

hmmm....

Talk about getting taken out of context !

I said " custom cam" as a joke - purely because it seems to be the trend when people ask !

Nothing to hide - just been flat out.....

This car has 1" & 7/8' Di Filippo 4 into 1 headers , and a full , twin 3" Di Fillipo system -

It has an under drive pulley kit fitted and as I said before , the ram jet otr.

cheers !

[APS Luis]

It does seem like alot of torque. My blown 5.7 makes a little more than that. Pretty good results :) good work.

Rear wheel torque can change depending on the dyno , the roller diameter is a factor.

I will contact Todd at mainline and get him to explain some more - I'm sure there is a thread regarding this somewhere :)

[HEKYEH]

Considering other cars with similar modifications are making anywhere from 290-330rwkw....what would be the main reason(s) you have achieved such high numbers? I'm still kinda new to the whole engine modding scene...so is that cam you have used a totally crazy cam or something?

By my knowledge it's a large cam mate

Thats a big arse cam in a ls based road car. Gm's TK cam was considered big but this baby makes it look mild.

An no valve relief :confused: I'm impressed , no truly I am, knowing full well what a Comp 244x248 requires before entertaining piston to valve intercourse the instance you nudge 7K trackside with the L98..must confess I simply don't have the balls to try that one on :1peek:

.

[Leatherman]

Daily drive cam in my opinion. :goodjob::goodjob::goodjob::goodjob:

But agreed on the valve relief - that's a fair amount of lift and duration without flycutting.

Rgds,

Leatherman

:) I'll reserve judgement till I see the ET and more importantly the MPH....my Cam only VE went 11.7 at 117mph on street boots with all 306 RWKW from one Comp 249x263...an that kind Sir is an LS3 .

[SSV8TE]

Thats an awsome result lads.....Just under the 350 rwkw N/A...:goodjob:
Damn i know how hard it is to get that kind of rwkw's N/A and you guys have done it easy by the sounds.......again :goodjob:
Hope this baby might be at the dyno / open day you running in next couple of weeks?
Best of luck with the future of this weapon and good on ya for sharing a success that most people like to pull to bits....
Keep up the great work as those who know your shop will understand that you know your stuff:bow:

Cheers,

Shep gets 311 with an LS3, standard cam on LPG - that "sir" is fact google

....we can keep this up all day...but time slips and more importantly correct disclosure of weight and the cars top end MPH usually win out over any quoted dyno figures imho :)

Just interesting with that big a cam was there any fly cuts done? Also was there any head work?

It a fair comment though. Has to be more to this thN just chucking this cam in. Valve relief surely is a must.

Darn tootin :)..........

and thats the catch 22…First time Commodore owners ,and would be modifiers will think they have just won gold lotto reading this , Cam , Springs and Exhaust only for an incredible 347rwkw…..Those same canny folk within the LS1 Forum who do there own homework ,will already have priced the cam / Spring install + tune at 3 to 3.5K odd, exhaust complete $1600 ,now throw in a $ 300 OTRCAI and that’s fantastic $$$$$$ for the quoted dyno numbers ……..BUT :teach:Now ask the folk who do have those self same numbers ..But ONLY Those with the ET slips to back it……..I most humbly suggest that at the very minimum you can triple my original quote to run any sort of number to match your quoted Dyno sheet ...and I’m working on TRADE figures…an before anyone Jumps on my case over exhaust quotes.firstly I'm running 10.2 with above mentioned DFs + custom 3 inch......at under $1600.....if your too damn lazy to do your own price shopping..then go see Mel at Mr Muffler...just a hint mind you :)

[rosey]

great results fella's, I'm definitely a fan of the bigger cams now :goodjob:

Very nice result there.:goodjob:
Did the car owner request Di Filippo or APS recommend a full Di Filippo system because they're the best.........:goodjob:

How????? I'm really confused/interested

I'm going a 239/247 and even without milling the heads it wouldn't fit???

Camshaft timing.
No lining up dot to dot here boys!

.660 lift:confused: still cant see that fitting unless intake valve is opening as piston is going down:confused:

[HRT 8]

.660 lift:confused: still cant see that fitting unless intake valve is opening as piston is going down:confused:
Isnt that a fundamental of a 4 stroke engine.??? ;)

[SirNemesis]

Wouldn't adjusting the cam timing to suit PTV be a backwards way of doing the job? Surely aligning the cam correctly and flycutting the pistons to suit would yield better results.

[SSV8TE]

My 2 cents:
Durations wouldnt cause failure in PTV as logistics of engines wouldnt be right if they would but lift would be the biggest cause of PTV....
Correct me if im wrong lads....
My cam is a comp 238/240 .611" @ .050" on 112 lsa and no problems at all with 32 tho shaved heads too

[SVNLTR]

.660 lift:confused: still cant see that fitting unless intake valve is opening as piston is going down:confused:

I wont say much has it's not my thread-

but lift is the least of your concerns-

Lift is whats coming off the seat all the time-just not at a certain point

It leads me to my next ?

where do you check ptv-

@ 5 degree's,10,15,20 so on

whats the overlap,then at what timing does the cam make its movements-

Here's food for thought...

why does a l98 head yield more ptv with a big cam while using a 2.165 valve vs a 2.00-.10-.20.30 valve ?

These cams that we are talking about is not off the shelf items-their might be big duration ones in the book but when you order a custom cam you call the shots...as long has you know that their is trade off's

besides how much can you mill the heads without running into intake issues bolting up anyway ?

[BLACKVE]

Isnt that a fundamental of a 4 stroke engine.??? ;)

Yes but it begins opening before TDC were the PTV issues are.

Hope i'm not annoying APS as it's a great result, just interested in the PTV issue as a novice. Things such as big jims TK cam kissing pistons etc make you think anything like 235+ is trouble zone...

Andy i believe duration has a bigger impact, do you know what clearences your comb is???? My old 224/244 with .625 lift was acceptable but wouldn't have been able to shave the heads.

The issue of valves kissing pistons isnt just an issue of overall duration nor overall lift.
Different profile cams open valves faster than others, so the total valve event needs to be considered.
Andy, by saying anything with above xxxx degrees or above xxx thou of lift wont fit isnt correct.

Amen. Certainly one of the most bad ass cam installs i have seen. Hopefully we will have one of these combos at the track soon.

[scott w]

so where valve reliefs needed .

a simple yes or no ?

Scott,

No valve relief. And no hand relief either... If you are interested and would like further information give us a call and ask for Luis. (03) 97838300

Cheers, Nathan.

[scott w]

Thanks nathan , have an l98 Ve as myself and are looking at fitting cam in near future .

Don't mind the missis giving me a bit of hand relief .

[fastestls7]

Hey guys, if my information is correct i understand that you used a 227 232 610 113lsa cam last year and pulled around the 340 mark in an auto VE L98?

Sorry mate,
My statement was fairly broad but keeping it simple for others.
I know that durations and lift are a combination which can lead to PTV issues.
If the duration is longer then the valve is opening earlier and closing later hence piston travell getting closer to conecting with the valve so in all....Lift + duration is a combination that needs to be closely checked before the first load of fuel goes through the chamber.

Some reading for you lads that want some more info.....

[fastestls7]

.............................

[poolkeeper]

Top work APS :goodjob:

If you want more info, buy the cam and get the guys to install it lol :)

[Hellbent]

Must be an art to get the valve to rush open then hit the skids until the piston is out of range....then do the opposite when closing :goodjob:

[APS Fston]

Ok here it is guys,

Workshops have secrets.

APS Service Centre is a large workshop with a lot of experience its these things that separate us from the rest.

Our new and old customers like that we push the boundaries. They also love that we stand by our individual engine packages, dyno results and intellectual property (Secrets) ie: Cam specs.

And yes like other great workshops out there we back up all this by running track results.

We posted up the cam used in this car but by working closely with our engine builder we made some changes to the profile, this is the our part number (APS_011_GRND).

We do tell our customers every spec that there engine has but no we don't give up all our secrets for all to read...

So keep guessing guys lol or book in for your custom cam at APS u will not be disappointed.

Regards Mick.
