Whipple 2.9L SC coming soon

although true, but you look at a smaller engined gt500 guys that are pushing 700+whp, with just a s/c swap to a kb 2.8 and whipple 2.9 and 3.4 units. and thats with just an s/c swap no other bolt ons. and thats on a 5.4L engine, so i think a 6.2L will be able to support a 2.9L fairly easily. the question is, is how much power can the LS3 handle before it goes kaboom?

[nfamous209]

740whp at 17 psi.

nice tq curve there, doesnt look like that 5.4 struggles to spin the 2.9L s/c.

The key to whipples is their low IAT, with most blowers as you get compressed you create heat and heat the charge. Whipples are known and proven to be one of the coldest charges/PSI that you can get. This is why GT mustangs can get up to 100+ above stock RWHP on the stock bottom ends. Its more than just PSI there are NUMEROUS other factors with boost.

I think your reading into the displacement too much. When it comes to blown cars, displacement plays a much smaller role. There are guys with the 4.6's running stock long block 03/04 Cobra's pushing ~700 rwhp now with the newer larger blowers.

Evil Twin or someone else with knowledge of s/c,
If you were going to put a s/c on the 6.2 and you were only going to add long tubes, cat back system, cai, and maybe a few other small bolt ons without going through the bottom end which s/c do you think best fits the LS3? How much rear wheel hp do you think it would add also?

Wow I cannot wait to see the results with some of these. When I first looked under the hood of one of these I drooled over all of the under hood space for a big single turbo and the very little work it will take to mount a FMIC. Though I have always been a HUGE roots style blower fan, especially when Whipple and Kenne Bell get involved. Its great to see everyone jumping on the market to give some great big HP options for these cars.

I posted this question a few minutes ago and have another one.

The next is that some guys were saying that they wouldn't go with a gear change when the 3.90 gear was out if you raised your hp too much because all you have was a tire burner. Anyones thoughts on these 2 questions????

IMVHO - you should have an understanding of what your expectations for the car are going to be. If you want to max' out what you have now, but leave room for expansion later, maybe a bigger SC (i.e. a 2300 vs. 1900) would be better so when you build-up the shortblock, you can turn-up the boost and have a lot of room to go. I've read the headroom for the 1900 is up to 800 horsepower though, so I think Brian's point is there's no need to put a 3-plus liter SC on a car that is only going to see boost lower than, say, 10 psi. I'm not speaking on his behalf, but I remember reading posts by him that they found their 1900 made like ~ 40 more horsepower than the 2300 in the same car at lower RPMs. The 2300 eventually passed the 1900 at higher engine speed. I'm sure that's what I remember reading. He can clarify better though. Anyways, it seems like the new TVS-superchargers are at least gaining ground with the popular twin-screw types, like Whipple and KB. I haven't seen any centrifugals yet and haven't had a chance to check for a few days, but they shouldn't behave much different than they have in the past. They have great power potential too and I'm sure we're going to be reading about them on these cars very soon.

I'm just suggesting to get a plan together based off of what you want. Some superchargers (Procharger comes to mind) need regular oil changes that require you to remove them from the car (I think the intervals are something like 6,000 miles); some SCs need to be tapped into the engine oil system for lubrication (like Vortechs in the past). I think the Magnusons don't need servicing until like 100,000 miles and the twin screws, like KB and Whipple, are probably the same. If you want to basically install it and forget it, maybe the centrifugals have something going against them because of regular service. You need to figure out what you expect and go from there.

For me, I'll be going with a Magnuson most likely. I've read the most about them and have seen nothing but great results. I know the twin screws are great too and will continue to look into them because just ask how much the Mustang guys like them.

As far as the gears, if you have the traction and drivetrain to put the power down without breaking, the higher the better (within reason) for the most part. With the mods' you're talking, you'll probably be close to 550+ RWHP and with 3.90s, the tires are probably going to spin if you even look cross-eyed at them. If you run around with drag radials, it won't be as bad, but that much power, regardless of 3.42s or 3.90s, is going to be tough to control on the street.

JMVHO.

I never said it would struggle to spin it. My point is at STREETABLE power and boost levels and smaller supercharger will ALWAYS be quicker and faster. The 2.3L (2300) supercharger is about the biggest blower I would run, and it is good for 950HP.

[2010 2-Tone]

Even will the guesstimated 550rwhp won't the T/C be a big help and keep the spinning under control and is it worth it to invest in the 3.90 gears? Do ya'll think you could stay in 3rd gear or would you think you would have to shift that extra time running the quarter? Would that extra shift be worth it if your were trying for a good time? I know the 3.90's over the 3.45's would feel much stronger but would it actually help the time in the 1/4?

[WeeZee]

Im not much of an expert when it comes to blowers but it seems like these 6.2L LS3's in the Camaro SS would be sreamin with 4.10 gears and 500 to the wheels. I guess it depends on how much is enough. Imho if you can dip into the 11's with a daily driver on street tires (not slicks or drag radials) you have a bad ass car

[WeeZee]

Whipped Cobra's are the fastest in there world. Kennebell's are sweet but get beat most of the time by Whipples. I used to have a 2003 Cobra "Terminator" Eaton swapped (ported & pullied) 2003 Mach1 that I sold back in january. I still have the Mustang pride in me. The only thing better is a Hellion Turbo or custom Twin turbo setup

[nfamous209]

i'm just happy theres companies making stuff for the new camaro. the more the better, drives competition. Still wish whipple made a lil 2.3L setup for the 98-02 F-body's :( dont mind putting a kmember spacer, buying some moded motor mounts to lower the engine a bit more, and choppin the cowl area a bit to get that sucker to clear.
