E85, John Shepherd, Buschur Racing and some good power.
John is working on the car now.
The car has the stock fuel rail on it right now which I am pretty sure is the biggest problem. On gasoline it will run out at about 700 whp on our dyno. The fuel he is flowing right now on E85 puts him at that range. He is also running standard twin Walbro's, he will be sending them back to us for a little tweak to the pressure bypass valves. With the new rail and pumps tweaked the car should have enough fuel for more power.
The car runs the stock regulator on it so the base pressure is only about 35 psi, that means the pumps were only putting out 70 psi.

Twin 1000cc injectors, twin rails running 2 injectors per cylinder.
Since the Walbro's are coming out why not see if you can come up with a twin 044 setup for the high HP E85 Evo's? Hell the Supra guys got someone to make them a triple hanger for 3 Denso's.

Wow I am shocked to see so much interest im my car. I have had it since 03 and just never drive it.
The car is an 03 with only 6,000 miles and is extremely clean and as stock appearing as I can make it like I like them
I had already run a 9.96 on the first decent pass on the hta but it was far from a great launch. The 9.96 was also on the bone stock intake and throttle body. I could tell right away from the log that the v2 was picking the power up past 6,000 from the a/f.
The car is absolutely tame and driveable on the street and with the new tune the intake and t.body it would have went much quicker. It is apart for some changes that should bring in more torque even sooner as well as trying to get some more fuel to see how far it will go with more boost.
Someone asked before about the 4.11 and yes this was on the 4.11. With the little 225/45/17 drag radials the rpm would have been way to high.
thanks again for the interest.
