ST-series T4 turbo
It also might get slapped on before I go to the track on July 8th!!!!! Putting the 10pt and a bunch of other goodies on so I don't get DQed!
alabama to florida in 2days bitches.........

And 52172: ~8.5:1 compression on my ride.

lol at the compression. Just reading a little too fast after a long day at work. My main competition will be my car and myself. I have yet to make one pass with my car turboed (or the 3 speed). The car will also be untuned until we park it in the pits, lol. We will be data logging and tuning after every pass.
I think if the car hooks okay I should be in some sort of contention for the built motor single power adder class. Last year the winner (351 fox with big vortech) had about a 9.50 car.....BUT he popped a coupler in the final round and our very own Mr_president blew his doors off with a 10.22, lol (along with getting DQed because he didn't have his cage in yet).
Have you dynoed it at the current 15 psi level??
And then at 10 psi??? i bet there isnt a huge diff in power between those two.....
I would never put anything smaller then an 88mm turbo on anything over 400ci's.......
I was seeing back pressure issues with a GT42-76mm turbo (it has a T6 flange) with only 370ci's....
A T4 flanged 88 would help out alot, but up top your still going to have some flow/ back pressure issues...

Your competition won't stand a chance......
Kind of comparing a Honda to a Z06....lol
oh yeah and this is probably a dumb question but I am still new to the turbo world, on the 76 there was a reference port on the compressor housing on this one there is not?

You can either tap the comp cover or just get the reference from the intake. Most do it from the intake so we don't tap the covers.
