Went back to the track on Friday 4/27. Decent racing weather.
DA = 1600ft
2010 Touring 7AT
Mods are:
Empty trunk - 3510 lbs with driver
Enkei 18 x 10.5 rear wheels w/ MT ET Str SS 285 tires @ 25 psi
Stillen G3 Intake
48 row cooler (ET penalty due to weight)
Mobile 1 10-30w oil

Ackrapovich CBE

3 gal of 91 Octane gas and 2 gal of 94
Factory Nismo Front wheels and 285 tires (weight penalty over my MT skinnies)
NO TUNE
3.69 Gear in the VLSD
Two new mods, the Stillen G3 and the 3.69 gear. Car ran solid 13.40s all day. The new rear gear really helps the 7AT car for all round driveablity over the 3.33, and the sixty foot times were much more consistent. The Stillen G3 was a let down because there wasnt any noticeable gain in power. The 3.69 gear now has me crossing the stripe at 7K rpm.
Car needs a tune now, but in spite of all these mods the AFR was roughly 12.4:1 under WOT.
Ohh and I forgot to add, I noticed on the run playback (dashcommand) that the engine struggles to recover after the gear changes now...like the timing is slow and the mixture is too rich.
