This is just playing in the driveway Saturday night.


That was testing the 3-step and 2-step against the gates. only 4 or 5 psi, but didn't have an issue getting there.

How much rwhp does it take at 3,000lbs (your weight) to get into the 4's?

Not sure, I would guess 12-1300. It's gonna be tough.

We've not ran it up to 7k in high gear yet. We've turned it @6600, which showed 150mph, and @4% slip.

I will definitely make sure to stop by and check the car out this weekend while I am up at the race at SGMP. I hope to see a four second pass out of the car this weekend.

What kind of boost are you gonna push the big boy too? I know in another thread you said you actually had to add weight to get anymore than 30 psi from the pt88. Or I may be mistaken.

We had to add weight to keep it from dragging the bumper all the time.

We are going to try to sneak up on the GT55, so we're not sure where we will land for total boost.

Im sure it will take a lot less psi to achieve the seem power with that beast.

1.20 60ft
5.08@141.7 so far.

That's with @8lbs less boost than before. We're gonna throw a few more lbs at it on the next pass.
