At this altitude I at my 24psi I made 442whp. At sea level it is 442whp. The correction factor is 1.18. So that puts me around 375whp down to the ground at that moment. Sounds weak doesn't it? Well, when I ran my 13.3@114 I was only running 19psi. That puts me around 340whp. Altitude makes a huge difference. And up here you run about a full second slower than at sea level. I raced my buddy in his supercharged ctsv. He ran 11.7 at sea level and I wasted him. I raced another friend in his 500whp cobra and stayed dead even, and I was only on 15psi.

So at this altitude I would need around 450whp to run mid 11s, possibly low 11s. At sea level it should be close to a 10 sec car.

that is possbily didnt manny's car only gain like 20whp on vet with a EL manifold ?


Manny didn't ever use a log. he went from his revhard tubular to his protech UNEQL and made 20whp more. A log manifold (especially one like mine) becomes a huge top end restriction when the boost gets turned up.

Check out Full-race.com and look at their dyno numbers on their sr20DET. They gained somewhere like 65whp @ 13psi.

Maybe I will just settle at having the fastest Gray 5-speed VE-T powered SE-L haha.

Move down here to South Florida, then you will see the numbers you want.

Turbo cars don't experience the full second difference between altitude changes. Only N/A motors are affected that much. Turbo's offset a lot of the loss because you have to remember it's still going to compress the thin air and pack more of it in there. I can't remember what the exact difference for 4,000 to sea level is. But I know for N/A it's 9/10's of a second. Everyone just rounds up.

Going from sea level to 4500ft? Perhaps not, but it is close. Think of it this way. Is 80whp worth a full second? Maybe not, but it def makes a huge difference.

Small turbos for street cars are great.

Like Kevin and Andreas said that is a perfect set up for a street car. I Have seen Kev's car run aswell as a few cars Andreas put together and they are very damn impressive.

Andreas I was most impressed with Joe's red 200sx. That thing impressed the hell out of me.
