***UPDATE***
All I can say is this nasty little truck is a blast to drive! Tuning is comming along great and finally got to make my 1st WOT pull in 1st gear, it is insane. Can't believe how hard these twins hit, just blows the rear tires off (granted they are regular old 235/75r15 street tires) and gets very angry very fast! I will soon have some good WOT videos, but for now here is what I have.
Great thing is the fuel system is looking up to par for what I want. on 10.3AFR @ 185KPA (13PSI) my duty cycle was 60% running e85. Once I lean it out a bit, I think it's hold 17psi-20psi without a hitch. DBW was a trip trying to get the stupid thing to quit shutting down under boost, but I finally figured it out haha.
BTW, these little T4 gt35's are very loud, sound sick! Spool is alot faster than I thought it was going to be, data log shows at 2300rpm (126kpa) and by 3100rpm (185kpa) which shot right to 6130RPM in a violent tire spin fury haha.
ENJOY!
