Ebay GT45 + 5.9 Magnum + E85 blow thru
Latest update. Ran at the track last Friday. Got 3 passes in and on all 3 the engine sounded like it was cutting out or missing really hard. My first pass was the best with a 7.30x at 92mph. I installed the 2-step firmware on the Fitech unit and wired up the 2-step to the brake light switch. I was able to foot brake it on the 2 step and get 5psi before the launch. Very promising. Car is hooking good, going straight. Unfortunately the track wasn't clocking 60 foots that night.
Fast forward a week, I discovered that the miss was actually a loose vacuum hose going to the blow off valve. The BOV was loosing pressure and flapping up/down creating the sensation that the engine was missing. I replumbed my vacuum lines from the turbo to the manual boost controller, waste gate and bov. I turned up the pressure and got it to around 10psi, peaking as high as 11.3psi and took it for a few test blasts on the street. It's running great, power feels awesome and AFRs and timing are right on the money with the Fitech. Next tnt is in 3 weeks.
