Just like the title says. Just want to see what kind of numbers people are piling on this combo. Please list heads cam psi and fuel setup if you don't mind. More specific focus is what rpm boost starts coming up.

Don't know all the details, but 98z28CobraKiller has been 8.9's on a 370/pt88 combo at a pretty hefty raceweight.

Z28cobrakiller's has probably pushed this combo further than anyone else in a full weight car.

I also know that 01Z28Camaro has a 370/PT88 set-up too. You would have to ask him what it made though.

I am going to put a 6.0 in my SS this winter and am going to wring the PTE76GTS out first to see if I can hit 9.0x @150 with it on race gas, then put a PT88 on it and shoot for 8.50's!!!

01Z28Camaro

I haven't put mine on the dyno, I drove mine, yes drove it 5 hours to a track on the stock rims with some nitto 555rs. Yes the ones everyone seems to hate, on 15 psi and possible the most humid, nasty weather day I could have went. I ran 10.4 at 142 mph, hitting the rev limiter before finish. 2.0 60 foot, 7.0 at 117 mph in the 1/8. Was pulling timing in 3rd gear, no meth, just some half tank of 91 and added 5 gallons of 110 for safety.

Easy mid 9s will be had with my prostars and transbrake, car runs 1.39 60 foot on avg with transbrake.

that's awesome. what's your compression ratio?

01Z28Camaro

9.5:1

Basically on 20 - 22 psi I should be in the high 8s, this car is my daily driver, If I'm going somewhere it's what I'm driving, only exception is late at night, Since I need to have full exhaust put on it still.

nasty_ss

what's your fuel setup?

I put down 695whp / 740wtq on my 370ci iron block with l92 heads and a TU1 cam, 18psi tc76, just blew that turbo, now upgrading to a PT88, i'm shooting for 900+ whp, but that remains to be seen...

Went 9.65/143mph and 145mph at 4800 lbs with 370/pt88/317 heads 20-22psi. This was with a smoked 2nd gear 4yr old stock 4l80e. Combo had at least .2-.3 left in it. Boost started to come in in mid 3k range and would rev to the 7200rpm limiter with 215@.050 cam.

im running this combo with stock 317 heads. at 19psi on a dynojet it made 789 and 1012. not sure why the readings were high on the tq. the car weighs in at 3675 with full tank and me in it and has been 9.25 at 153.3 driving to the track and driving home. the cam is a Futral custom grind. gonna lean on her more this year and see what she does. this is on 93 octane and some meth injection

I have a pt88 on my car now with a 5.3 looking for 750 through a 9inch 4l80
on e85 looking to go 9.50s with this combo.
the lil 5.3 at idle will barely turn the turbo
