hello, everyone

Thought I would start this thread, since I believe it existed in the Supraforums (mk4edition)
and have not found to many stock turbo dynos past the 500 whp. mark.

so today, I Tuned my supra LE ( dynoJet) in the Caribbean ( really hot today) @ 12 noon

please share your thoughts and dynos and get this stock turbo info going.

Mods.
1) induction performance Downpipe
2) stock muffler after downpipe
3) boostmod3 (Custom tune)
5) JB4
4) vp x85 (E77)
6) WMI installed

OTS maps where
93oct 434whp
E30 456 whp

here are some pics...

observations:
peak boost was 20psi but falling to 18psi @ 6,000 rpm to redline. we will recheck for boost leak and re-dyno soon to see if we can maintain 21-22 psi to redlilne maybe see 10-15 more..... hopefully.

Tq is crazy and will spin the stock tires in 3rd gear.......

On E85 did the HPFP or LPFP have any issues? Did you do any pulls without the meth on just E85?

High pressure and low pressure fuel pumps. The HPFP sits in the head, the LPFP is in the fuel tank.

on th dyno we had no issues with the pump got other codes though

CD990B
CD990E
21B056
21B055
11A605

yea, just another step to hold us over until we finish our big kit. We were going to do a 6466 kit, but i think we've landed on the Garrett GTX3584RS to base our first kit around. Good for 550-1000hp. So should cover most people.

Pure turbo upgrade is quick direct bolt on upgrade that is good for 600-700whp. Which will suffice for most people. Fast spool and good power, good on the street and track.
