Contour Enthusiasts Group Archives Forums Modifications Forced Induction ADC kit question

Yes, I did. Hence why I'm following suit.

Hmmmmm so in that case a 3L swapped in in the same situation should put out more power. Honestly I'm just curious what the T28 would do on a 3L. I know there is a 3L kit for a reason. It doesn't seem like the extra power is put to good use though. Why add the extra power when you can't put it to the ground anyway unless you just want to impress people with numbers?

So is the intercooler in the 3L kit any larger or is it the same one which is still undersized?

Well, just to put it in perspective.

A 3L engine bone stock with just a cheap, properly sized t3/4 turbo, basic intercooler, and the stock ~6 pound spring in the wastegate will allow you to throw down 300 wheel horsepower basically any time and anywhwhere! This is on the crappiest gas you can find too.

That T28 will be huffing out 14 pounds of boost on race gas with ice in the intercooler tank to make over 300 wheel horsepower....and ball bearing T28 cost a bunch more too!
Hell, just putting a bigger turbo on the 2.5L can do the same thing but you'd need about 9-10psi in order to do it.

The thing I've been saying for years now is to make a plan with proper goals. Then use the most direct and cost effective plan to get your goal. Ideally do it in stages if money or time is an issue so that you can actually get some usage out of the car after each mod you do. You'll be able to iron out bugs in the setup easier and be more satisfying.............rather than just pulling an SVTProdigy and going for the Gold on your first time through, and not even placing in the finish.

I think I can back this statement up:

T3/T4 hybrid "ebay special" running on a 2.5L SVT engine with a completely blown piston. You have seen the pictures ... haven't you? No, here you go:



Basically, a 2.5L engine running on 5 cylinders and she still put down 220whp! Now imagine running on all 6

For the record, I couldn't get the car to boost over 4.5psi. Not sure it that is because all the boost was leaking past that cylinder or because of the crappy wastegate design. Regardless, she ran like SH!T on 5 cylinders with minimal boost and still managed decent numbers considering.

Well, did YOU do the dyno or was that what the company said it dyno'd at? It may have been getting something out of that cylinder when it dyno'd 220. Maybe not.
I would expect it to still be able to fire under boost since the pistons was still reasonably whole though.
The turbo was cramming in more air than could escape past the wrecked piston.
