E-85 track times!

[Fourdoordsm]

Well guys,

Only change from my first 12 second time slip from last year is that this one was on E-85 instead of 93 octane, and EVO VIII MR wheels with Advan tires instead of Enkies with Blizzaks.

The stock fuel system can only handle a few seconds at high boost / heavy load before I go lean. Running through the gears, boost falls off fast enough that this isn't a problem until I get into 5th gear. After 3 seconds in 5th gear at over 21 psi of boost (and over 100% duty cycle on stock injectors) I start to go lean and have to let off the throttle.

Even with this issue I was able to pull a 12.916 @ 102.81 I was planning to crank up the boost higher, and advance the timing... but with this issue I saw no reason to push any harder on the stock fuel system. Before I discovered I was leaning out I made one run WOT the whole way, not the best launch but a better MPH on that run of 104.4 on a low 13 second run.

I can't wait to get the double pumper, 1000 cc injectors, cams, and ported intake manifold!!!!!
