2.9L Whipple or MP2300 SC?

[Rock3t]

Hi, I'm really keen to hear some experiences people have had with either a Yella Terra 2.9L Whipple SC, or a MP2300. I'm trying to choose between the two, and I'm undecided.

I have a LS2 with a CAM & exhaust and only want to run around 8 psi for now. But thinking ahead, if I build the engine with decent rods / pistons / etc. I don't want to pay twice for the SC so want something with room to improve.

I'd also like to have as quiet a set up as possible (primarily at cruising speed), and reliability is more important than outright hp. I'm also after instant power in the low to mid range, as it's a street car.

I'd appreciate any comments.
(as there aren't many useful posts in the search history that I could find).

[vyls1wa]

send harrop an email in regards to how far their blower can go, from the ammount of people that install MP1900/2300 and earlier versions it seems to me that they are the way to go over the Whipple for ease of install, reliable, quiet and power to boot, will the 2.9L make more power? it may, but will it give you the quietness your after?

[Roonstain]

HTV series harrop blowers are much quieter than previous designs - have a look at them mate

[Docka83]

Magnercharger and Harrop both run the 6th Gen Eaton iternals. Mine is very quiet, only a slight whine initially which you can hardly hear.

[Popeye1]

any of the harrop blowes wil give you instant power that wil put a big smile on your face and with a cam injectors zost tune and 3.9 s wil se a very low 11 second pass in sydney you have Russo perfomance and Castlehill xzost both very good at their job and have WSID slips to show they mean buisenes.:goodjob:

I'm lead to believe the Whipple has a lower intake charge, when compared to the 2300. So this is where a little bit of power can be made. However, I've also been warned that too big a SC on a stock internal motor (other than CAM / valve springs) is no good either. The price difference between the 2.4L and 2.9L isn't that great when you include the extra standard bits that come with the 2.9 (8K pulley vs 6K, better balancer, etc).

They both have pulley upgrades to increase boost, but I've heard some shops say they've had warranty issues and poor performance (as in issues with the sc unit itself) when going above stock boost on the Harrop 2300.

I've talked to a three of four well known shops, and they all tell me something different. Just don't know what /who to believe. I've 'made my mind' up 3 or 4 times now on which path to take! I'm pretty keen on the type of sc, just don't know which one is best.

That's good to know, has to pass the cop drive by / wife tolerance test. Any vids of it cruising you could pass on?

[SharkBiscuit]

are there any bonnet clearance issues with the whipple?

[Kingston_99]

I was in the same boat last year, i ended up buying a HTV2300.
Its not on the car just yet as im looking into a stroker kit. But from what i heard, the HTV are quite. I asked Harrop if they could make it loud like the older versions and they bolted a glimer belt to the rear drive of the SC unit.

[Rock3t]

Not with the 2.9L (and 2.4L) in a VE.

The 3.4L is bigger, not sure if that fits, but it's way over kill for me anyway.

[ATOMIC MALOO R8]

im running the under drive pulley kit( 85mm top stock size ballancer with 1>1 on the rear drive) on my htv 2300 on a camed ls3 and geting 10.5 max psi
i was told by a few engine builders that 440 ci is about as big as is advised with the 2300
as you have to spin the blower to fast if you go any bigger in ci

[ls2GTS]

Have u considered looking at a Procharger kit?

WHAT!!! go the bogan way if the side mount blowers... ummm would you even call them a blower??:spew::spew:

I've always been a valley mount fan but I think you'll find there is more evidence to support valley mounts as the "bogan" blower :lol: Look at all the burnout cars for instance :lol:

[ls2 cruiser]

kingston 99, The gilmer type belt at the rear increases the revs of the blower 10%. I was glad to get rid of mine as it is too noisy. Pedestrians 200 metres ahead were gasping with awe. My neighbours asked me to get rid rid of it as well. I cant hear my new HTV2300 as the exhaust is a tad loud.
Rock3t, the 2300 is made for a 400 cube engine the 1900 suites a stock ls2. In saying that you are better off with the 2300 and turn it down a bit. If you stroke the ls2 then you will have 403 cubes and then you will need the 2300 as the 1900 is then a bit small. The whipple and the harrop 2300 have similar intake temps until over 15psi where the whipple wins. Who would run more than 15psi in a street car anyway. Make sure you drop your static down to 9.2:1 and dont go above 11psi at that static if you stroke the beast. The ls9 engine specs are 9.1:1 static and 10.5 psi in.

[Popeye1]

ive got the old 112 vally mount and on a stock internals even the valve springs were factory on 5.5 psi this what a bunout looks like.
YouTube - Cons Smokey supernats 09
the new setup 10 psi injectors valve springs timing chain cam walbro pump 3.9 diff pacemakers 318 rwk with 499.9 ftp torque and 11.3 1/4 mile not bad for the amount of mods, you wil never regret it mine is very loud it wil drown out a 671 but that what i like and if i drive it normal its very quiet.

[ls2 cruiser]

I am talking about the gilmer set up being very noisy - not the hh122 blower itself. The HTV 2300 is very quiet. I did like the whine of the HH122. Ken Nunn has done back to back tests with the different brands of blowers and he said that there is not a lot of difference between HTV and whipple.

[vxssblown]

I also have a hh122 and find that it runs out of puff to quick, down lown in the revs it not bad but if you get in to it it loses grunt in the top end, i might have to try the 2300

I would be going the yella terra charger,we have been working very closley with yella terra on this charger,whipple chargers are the best chargers out there ,you will be able to sample this charger on our workshop ve shortly.

hasnt yella terra being working on these for over a year? i am yet to see a kit you can buy and put on.

buy harrop, get everything. install. done.

... whipple chargers are the best chargers out there ...

Them sounds like fight'n words!

"Best" is relative ... depends what you want to achieve. I have an intimate knowledge of the Whipple, Lysholm, & Eaton-based products and i cannot state that any one of them is "best" as it depends on the application and expectation of the purchaser.

the fact still remains, workshops have been pushing the yella terra & original style "whipples" for years now. Yet there is still no one selling a complete bolt on kit like the harrops/magnuson's(pwr's) etc.

i'll add, that this is not a bad thing. but it's a bit late isn't it?

Yella terra released the kit about a mth ago they are even on eBay as a full kit:)

You did mention it was coming when I had a look at the twin turbo setup at your shop a couple of months ago. At the time, I was keen to do something quicker, but plans changed (due to chasing the water issue I had), so now it's an option.

Given the parameters I have, what's your opinion on what's 'best' for me, and why?

I was talking to Smithy (I think he's the owner / manager? - although I didn't ask) from Yella Terra at the SummerNats, and there is a bolt on kit now.

That was my thoughts on going the 2300 over the 1900. I can't see myself ever going above 15 psi on my street car. However, if circumstances permit, a rebuild with better rods / pistons and possibly a stroker crank would be on my wish list. Which is why I want to spend the money on the first stage correctly, as I don't want to have to fork it out all over again like I've read other people in magazines do over and over.

Changing the comp would be ideal, but it's most likely not going to happen with the SC install.

[HYMEY]

Hopefully the VE doesn't throw a rod out the block after the whipple goes on eh sonny:stick:

[SAMCRO]

I like how ppl say "get this, it's the best" ummmm... hello!! facts!!!
Not all of us know how to pull the engine apart or what to get, when and why?!!!! You expect ppl to get something just coz you said it's best... Yes ok, here is my $15000, it's just a small change...NOT!! :stick:
That's why I love going to Chev's!! You are explained everything to the small detail and if you still can't make a decision then they will SUGGEST what best suits your application..and then they'll invite you to have a bbq and beer regardless if you're buying or not...:bow::bow:

Yes, hello. :) fyi i left work after my last reply and you were "chopped" by the time i got home, so i didnt get a chance to see your reply.

either way it was all light hearted humour on a late friday, nothing that had to be taken seriously.

I thought you'd been around this place long enough to work that out.:smilesandbanana:

If this is the case then wait til you do your engine mods before selecting the blower, that way its a new cam and bolt on the blower when the time comes.

Before you have a monster blower running under efficient on a stock motor, and from my grasp (from a couple of posts from Harrop) a 2300 on stock motor isnt ideal and if it were me I wouldnt want to be selling a blower to fund another because my engine needs more air than what I bought first. Build the strong motor and run around on a nice cam until the funds for the blower are good to roll then order to what specs your motor has been built to.

You make some good points there, having the stronger motor would be the better option. Only problem is I'd like it done sooner than later, as I want to enjoy this car with my father. He's terminally ill with a degenerative muscle disease, and can't get around very well. It's hard for him to get in and out of the car, and each week that goes by, he gets worse.

How much should I budget for a set of rods / pistons / labour - as a rough guess? I'd probably need a new fuel pump as well.

[stockergts]

you can get a forged bottom end cheap 2k or can spend 4k and over it really comes down to how you are going to abused(not use) it

I'd tell you to test them both before you purchase mate!

Back in 2005 I tested the Harrop 112 and the Whipple 2.3 and the Whipple had by far more power and sounded better plus the belt was front mounted so looked like a real blower!

Now I have the 3.3ltr Whipple and next on the agenda is the 4ltr! I would not own any other blower (exept maybe a 1471 but even then I'd probably opt for the new 8.3ltr Whipple).

Yes, they are more expensive than any other blower on the market but you get what you pay for!

Each to their own with blowers but in all honesty, there's nothing like a twin screw Whipple mate :bow:

I ended up going with the MP2300. Black series with the VCM OTRCAI.

It's getting installed now, and should be done in a few days.

I'm guessing you mean Harrop HTV2300 (not MP2300)?
The Magnuson's MP2300 does not currently adapt to the VCM OTRCAI without some tweaking.

[exwrx]

FWIW I had a good look at the yella terra whipple kit at summernats and was very impressed.

Spoke to Jim the/one of the owner/s and we discussed the initial issues. I was pleased to hear that they refused to release the kit until it was spot on :goodjob:

I agree, it was a good looking kit. Only thing is, not many have experience with it and there's no OTRCAI set up for them. For my purposes, I think they were just too big. But hey, that all changes depending on who you talk to.

[matt@YellaTerra]

Hi Guys,

I may be limited to how much we can talk about our product on this thread, but I feel I need to clear some of the speculation and help with some of the inquiries from this thread.

The LS ENFORCER programme has been under development for the past two years, we knew launching the largest, most powerful bolt on twin-screw kit for this competitive market, would have to involve a lot of R&D and be build with he right hard ware to support such a product.

At the Beginning of last year we manufactured a controlled group of (20) R&D pre-production kits which suited the full range of LS models using all of the blower sizes (Whipple 2400/2900/3400)
These were set up on our own in house test vehicles as well as kits sent out “confidentially” to selected YT install/Dealers both nationally and overseas for independent testing and assessment.
This included (3) VE Maloo Utes shipped over to the US fitted with our VE 2900 Enforcer kits to take part in a 'PowerTour' across the states, which proved a perfect testing ground for reliability, durability, temps and power figures at various altitudes and to show off the grunt of our Aussie developed kits. :)
The kits performed as expected and in some cases surprised us with the amount of power increases some tuners where getting. :goodjob:

The product then was launched at Summernats this year with several kits on static display and our Silver VE 6.0L with the 2900 kit fitted doing the rounds and running up on S/Nats dyno each day.
When we arrived back in Melbourne we where inundated with orders and requests for the kits in January, whilst our manufacturing was on XMAS break. So the small amount of pre-production kits were snapped up. This delay in manufacturing of the key components delayed the supply around the country to our selected dealers like, Maranos Performance, HPF etc. who I now have been pressured for supply, for that I apologise, but we will have this resolved in the coming weeks and we will post up on our YT sponsored site the LS1/2 and L98/LS3/LS7 kit types available.

There’s no need for me to blarr on about the advantages and efficiencies of Twin-Screw units over Roots units nor the power of 2.9L units over 2.3L units, a quick 'Google" search will give you all the answers you need to make the right decisions for your application. google

Just to answer a few queries on his thread:
#The VE 2900 kit will work effortlessly on your standard 6.0L/6.2L, be more efficient and produce more power per boost than any other system, and with plenty of blower capacity up it’s sleave.
#On idle, the Whipple unit is as quiet as the Eaton roots based units you find on the Magnuson/PWR/Harrop reverse facing kits.
#On acceleration you find the whipple tobe a little quieter (pending on setup/application) because it’s usually working at a lower blower rpm speed to produce the same boost/power.
#The intake system also dose play a big part on the level of whine any PD kit produces.

Sorry for the long winded post but its just to bring you guys up to date with the progress and clear some speculations on our Twin-screw product.
I look forward to answering some of your positive questions, back in our sponsored part when we post up the kits info, specs and prices.

Cheers.....Matt.

You'd be worried if the 1.8L blower made more power than the 2.3L blower :lol:

[Tre-Cool]

Good to see some info directly from the "horses mouth" so to speak.

Like all things on the internet it's hard take anything written down as the truth when there's very little credible information out on the web.

I know i could be interested in a 2.9 or 3.3l headunit if i ever sold of my 2300.

[lsx 102]

I have the 2.9 whipple going on in the next week or so.I cant wait. Let you all know how it goes.

[Rock3t]

Thanks for the info Matt. I was torn between the 2, and still not sure if I went the correct way with the MP2300. Time will tell.

BTW, so far my car has made a best of 622 rwhp, with about 11 psi and around 14 degrees timing. Took a bit of timing out, and settled for 588 rwhp for the moment.

For my purposes, 622 rwhp is a little close to the limit for me (was getting a bit lean in the top end), and I'm getting it wound back a bit. Currently waiting on a different balancer to reduce boost, so I can have more timing put back in. I'm not really interested in outright hp, I want good response / readability in real world conditions (not just a number from the dyno).

I tend to agree....sometimes you’ve got to sift through some of that and find some independent testing done by respected installers/tuners rather then the manufactures talking up there own products.
We find ourselves (YT) taking more of the back seat approach and letting our products do the promo work.

I know i could be interested in a 2.9 or 3.3l headunit if i ever sold of my 2300
We are thinking of a 2.9L/3.4L Twin-Screw upgrade head unit/manifold package for the guys with engine mods that are starting to out grow their smaller roots kits.

Cheers......Matt Smith.

[macca33]

These jiggers certainly look the goods.

Just one query though Matt - I note the US Whipples to suit GM applications use the front-intake / TB set-up. The set-up pictured on your website on the silver VE SS is the rear intake - why aren't you using the front set-up? Not trying to cause a ruckus, just interested is all.

The wipple kit with front intake does not fit our cars.The pulleys dont line up. Thats what i am led to beleave.

Fair enough then - interesting that the LS3-based Camaro can use the front-intake though.

that in its self tells me you’ve made the right decision.

[izaks]

The 2.9L front inlet S/C as used on the Camaro, does not fit the 6/6.2 L as used in the Commodore. The Camaro water pump and drive pullies sit at least 40mm further forward. You have to buy the Camaro waterpump and crank pulley, and space everthing forward..... and then it does not clear the bonnet

[pectel]

Hi
just wondering,will the kits made for the Pontiac G8 fit the commodore VE.
i know the pontiac have different engine management,but is the programming the same?

[izaks]

The magna kit is a direct bolt on for both the G8 and VE.
Both use the E38 ECM.
