Default 760rwhp 777rwtq

Threw the car back on the dyno since building a new exhaust. Previously my exhaust was 3.5 right off the turbo, back to a modified SLP two on the left muffler and tailpipes. (muffler was modified to have a 3.5 inlet). The wastegate pipe dumped into the downpipe about 10inches after the turbo.

My new exhaust is 3.5in downpipe until the trans crossmember where it steps up to 4 inch. From there it goes back to a Magnaflow muffler and mufflex style 4in single tip. The wastegate pipe runs along the downpipe until it steps up to 4 inch, then the wastegate pipe merges in.

It previously made 760rwhp 740rwtq @19psi.

Tonight it made 760rwhp 777rwtq @19psi.

It didn't pick up any peak horsepower, but it gained torque, and through the midrange it's up about 100 rwhp/tq. (I think because the larger exhaust allowed the turbo to spool faster).

I also made a run at 11 psi, and it did-

614rwhp 587rwtq.

Intake temps were starting out at around 65 degrees, and ending up at 140 by the end of the run. I think I might try a larger air/air intercooler, or make the switch to air/water.

Nice to see your getting some serious power out of your setup. Now to get to the track and run a 9 second pass would be easy for you. Is the turbo on your car a custom setup you made or somebodies kit? Hope to see your car at the shop when I drop mine off in a couple of weeks.

I bet that intercooler works much better driving down the road. You should log the temps during a real run on the street/track before you switch up.

Awesome numbers by the way.

Great numbers Jim. I think most people know that his car isn't set up for the 1/4 mile. It's more impressive that just a 1/4 racecar. I once raced jim at Union Grove. He passed me so fast at the 1000 foot mark I thought my car died out.

Your making me want to start on my turbo kit.

Do you have any more video footage of your car? I saw a great video of a mighty impressive burnout you did.

Car isn't for sale is it?

Nice numbers! Any plans on turning the boost up a little more??

Kinda funny that with both of us at 11lbs of boost we make nearly identical HP.

Nice numbers!!!! My question is, what kind of clutch setup/tuning you have in it to hold all that insane power?

Thanks guys.

houseofboost- Thanks, but I've got no plans to sell the car.

Rob- Yeah, I will turn up the boost. Waiting for my new wideband. (last one died). Our cars made similar HP at the same boost level, but yours made alot more torque. I'm guessing your boost curve comes on faster because of the smaller exhaust housing. (more compression can't hurt either). It will be interesting to see how far you push that stock engine.

Y2K_WS6_T/A- I'm using a Mcleod street twin.

Very nice.

I'm glad to see you experiment with the exhaust even if it makes the car louder than you would like... Are you still dynoing on 110 leaded?

Also Jim, I would be curious as to how big of a cam you could do, in terms of duration, until you had too much overlap. How much overlap would a 230/230 cam have @ .050?

what do you think you can run on 93 pump only or is not a thought for you?
also is that gt80 ball bearing and how far do you think it will go hp wise?
