Will this void my warranty? Bwahahaha :lildevil:

There's a used kit (this exact setup) available right now (I'm not going to say where) :D for $6000 or $10,000 installed

Will the turbos fit on the V? We should have more room in the engine bay than a C5 right? :D

I miss my turbo 944 and the pull when boost comes on - I've been kicking around the idea of twin turbos on my corvette for a long time but imagine them on the V - what a sleeper... no one would see it coming if I pulled the V badges. :D The stock rear end will support at least 550 hp right?

Take lots of pics of your install. As soon as my warrenty is up Ive gotta do something to run with the 09!!!!!!

My wife just continues to shake her head at me.

yeah there are people out there with 550+HP setups with the stock rear end. i think as long as you don't dump the clutch anywhere in 1st gear you'll be fine :p

I have both so I can tell you about rooms...

Caddie has more room around oil pan because it doesn't have the bat wing oil pan.
Caddie has more room by the windshield because it is not as slanted as the Vette.
Vette has way more room around the sides. When I first got the Caddie I decided to swap the spark plugs. Then I saw the room and decied to quit and drink beer instead.
Vette has more room at the front as the engine is pushed back into the engine bay. 50/50 weight distribution ftw.
But the caddie has a huge empty space between the actual bumper and the bumper cover which is perfect place for a intercooler.

As far has making a vette kit working on the caddie...may be the exhaust manifolds will work and turbo won't hit anything but all the rest of the piping will be an issue. Not worth it.

After looking at the pictures of the setup I see what you're talking about - there is no way the C5 kit will fit, all the plumbing is wrong. I was really getting excited about this - six thousand dollars is a bargain for the kit but... all the plumbing would probably be hell because it would all have to be custom made or pieced together and look like crap. That's one of the best parts of the Lingenfelter kit - the fit and finish looks really professional.

I see you've got a twin turbo C5 - I have a new role model :D lol That's got to be an incredible car to drive - wow.

I'm not too far from Lingenfelter I wonder if they'd like a V to experiment with... This has really got me thinking now... on the other hand I'd probably be better off if I left the V stock... Once I start with mods I know I'll be screwed lol.

Unless one was going to do significant motor work, I still don't see the attraction to turbos on the V, as the maggie will give you just about all the boost you'd want with the "stock" LS6/2 motor.

Overdriven, a maggie can easily get 8-10 lbs of boost & I wouldn't recommend anyone going over that without some serious engine work.

Essentially, one needs to weigh the additional gain in power from the turbo "eating" less power than the maggie vs. the additional cost/grief of getting a turbo system to work in a V.

In my mind, it isn't even close; I'd go maggie if I was going to enter the world of forced induction (& wasn't already).

^^^ as far as I know there has only been one twin turbo set up by LPE & that car was for a gentleman in the UAR (United Arab Republic).

I like turbos over superchargers for 2 reasons:
1. If you are a cheap Do It Yourselfer like me, and know what you are doing, you can do it a lot cheaper then a Eaton kit and that includes a forged engine. But this is not for everybody and not for the impatient.

2. Boost on a supercharger is rpm based, meaning the amount of boost if based on the engine rpm. So if your max boost is 10 lbs, you only get that at 6k rpm plus. The turbos, on the other hand, boost is not related to engine rpm, so I can have 10lbs of boost from 3k rpm all the way to redline, bigger area under the curve. And I can easily change my boost level with a boost controller, while driving.

While most know the advantages/disadvantages of an SC vs. a turbo (which I won't rehash here), I would like to say that I can assure you the change in boost on a maggie is NOT very significant from low RPMs to high RPMs (well, certainly my car and at least one other SC V I know of).

Further, upon review of my dyno sheet, the torque curve is as flat as, say, Utah (okay, okay, a slight, down angle, but...).

As such, I remain very skeptical that a turbo on a V as compared to a maggie is going to yield significant improvements in rwhp/rwtq, to say nothing about the significant increase in cost/effort it takes to install one on the V.

I thought turbos spool up with an increase in exhaust pressure which, to my knowledge, increases with rpms??? I believe the supercharger delivers far more "drivability" when putting around town since there is alot more torque being delivered at the lower rpms. Turbos give you a huge kick in the pants once they spool up.

Turbo spool up is more related to the heat of the exhaust then the exhaust pressure. And turbo is more efficient at getting target boost, hence the wastegate to bleed off exhaust prevent boost surging. So yes it is some what related to rpm but it will get to the target boost way sooner and not at the redline.

I will use my Wife's STi as an example, it comes with a turbo from the factory. The car will hit target boost of 14 psi by 3k rpm, if it keeps on building up the boost, it will eventually reach stupid boost levels at red line and pop the motor. So the Subaru designs a wastegate that will open up around 14psi and bleed off the exhaust before the turbo to keep the boost level in check. So it will hit 14psi from 3k to 7k rpm. If it came with a eaton blower, it won't be hitting 14psi at 3k rpm.

Don't get me wrong, I like all FI cars, from supercharger to nitrous to turbo. Heck I even like N/A LS motors and have built several of them.

It's just that it cost me so little to build a turbo car that I just can't pass it up. The forged motor with ported heads cost me less then $1000, the twin turbos are Grand National turbos given to me for free from my friend, I get friends of the family discounts from the ceramic & powder coating shop, and I have access to a mandral bender in my friend's house so it costs me $0 to bend the pipes.

It would cost me more money to buy a used blower.

Sorry to disappoint you, but I ain't no role model yet.:alchi:
The C5 is still under the knife, I have a day job, a wife (she has my balls), and 2 kids to take care of. Plus I like to drink and party and Vegas is kind of a great place for that... So I can only work on my car during Monday Nights (agreement with wife). And I spend a lot of Monday Nights tinkering with my friends' other cars. So... progress is slow:crybaby:
But there is progress:

All this is possible because of my best friend Jon and his Mandrel bender. What kind of a guy has a Mandrel bender in his private home's garage? :bonkers:
