There is a thread going on a 2000montecarlo.com about the v6 version of the turbo in case you all are interested in any additional insight about cartuning and their products:

There will be people who doubt all the time, I am used to that after being on Club GP for a few years....only time will tell. I do fully expect tranny issues in my future, that's a given, just like when you turbo a V6, or just mod a V6 GP for that matter, a tranny rebuild is in your future. Can't expect to run with 500hp and keep the tranny stock.
Like I said, I have at least 10000 turboed miles on the car and she's still running strong. I drive 1 hour each way to work 5 days a week in mostly bumper to bumper traffic with this car, she drives just like a normal car.
We will be getting the final numbers from dyno and track very soon I just couldn't wait any longer until I posted more info!!

Well he did say 385whp. I think he implies that they dynoed the prototype kit and are waiting to dyno the production one. Are you implying that he's lying just because he's not using 3" piping? And how do you know he won't trap 115mph?. You act like he's trapping lower when he hasn't even given numbers yet. =) Low 12's in the 1/4, on the other hand, might be difficult with stock tires.

I am pretty sure slicks + this setup would snap axles. . .clean off
All though, I am quite interested in the kit, if the turbo was tunable, meaning I could choose between 4,6,8,10 etcetera PSI. .. I think that would be cool. Can't wait for pictures and videos!

The car is amazing, I personally don't care if it spins from a dig because I never race anyone at street lights and never go to the track except to get some numbers for people here, that will be the only time. Wait till you see the MPH from the track, I think you will be very surprised.
80% of my driving is HWY driving and the rest is in town, I don't drive like a ******* when I am in the city anyways. And even then if some Civic punk or Mustang guy or Porsche guy is next to me when I'm driving on side roads going to work, I only need to use 25% throttle and I whip him then go back to driving normal.
So if I am "racing" someone it's always from a roll since I am always on the HWY and that's fine with me because less **** breaks this way
This is just a bolt on kit, the power that it makes from a weekend install can't be beat. Then when we change the rear manifold (Front manifold is perfect for turbo, it's 300 times better then the front manifold on the V6 and you can make 500whp on stock manifolds in the V6.) the numbers will be much more improved.
P.S. about the axles, how many people here are previous owners of GP's or Impala's or Monte's? There are not many people in the Grand Prix world snapping axles and it will be a lot less on the GXP. Reason? You can't fit slicks on here big enough that will enable it to stick 100% on launch. I didn't think we could run anything smaller then a 17" rim on this car, so you won't be getting much of a 17" slick probably just a drag radial in which case it will still spin. Stick more then stock of course but it won't snap axles.
The input shaft in the tranny will snap before the axles do

He lives in Toronto so wait until they get to -40 in late December or in the summer when they get a heat wave. And I believe the power also that it CAN put down. But that number means **** all if you don't get all 385whp usable power (I.E. The car launching from a dig and taking off) to the ground which I can guarantee with FWD drive won't happen. It's iffy alone with bolt on's to add slicks to our car, so picture adding slicks with 140whp more to the wheels (can you say ouch).
What is all this dream world talk? I never said anything about not blowing gaskets or any of that. I just said, there is no reason to not believe he's producing those kind of numbers, regardless of whether he's spinning or not.

That's a good question, when cruising on the HWY I do see slightly better mileage, it certainly isn't worse which is awesome. On the other hand if you are in boost a lot, the average mileage will certainly not be as good as stock.
there are some weeks that I go through a tank of gas in the same amount of miles or better then I would stock.
I don't really have numbers because I drive in Metric Mode but I can check out what my average MPG is when I head home.

I don't really think we're in disagreement, so I'm not sure why you're replying to my post. All I was saying was that there is no reason to believe that he's NOT getting 385HP to the wheels. How much of that actual power is put into play will depend on traction.......we both said that and agree. lol
sorry for the confusion! Thread Starter

Lots of cars, Mustangs, Civics, there was a really, really surprised G35 coupe guy,well, he must have been surprised I didn't see his face because I was WAY, WAY ahead but ya know.

I'd practically would believe any # you'd spit out as far as HP! A 5.3L with 10 psi would easily make 500HP at the flywheel, especially if it has LS6 heads! I agree, I didn't buy my Impala so I can do 1.5 60', I like to drive like a human being and get on it from a roll! FWD is just not for that, although it can be done, it would just change the car! I got a SB2 Camaro for that! Although I'd go heads/cam/headers/tune/nos before I'd go Turbo, I'm sure that's a hell of a bolt-on upgrade that's probably hard to pass on for the money! Good Luck with the kit! Post some results!

CAN I SEE THIS THING?... WHY DOESN'T CARTUNING HAVE ANY INFO ON THIS TURBO ON THEIR WEBSITE? IN FUTURE PRODUCTS?http://www.cartuning.ca/future.php
