First time ever driving a RWD car this weekend...went to the track on saturday with my S14 with S13 SR20DET...mods are Greddy Intake manifold, Z32 MAF, FMIC, 3'' TBE and Profec B Spec II...i was at around 12psi with an occasional spike to 14psi...

first run ever:
60' 2.091
330' 5.748
660' [email protected]
990' 11.298
1320' [email protected]

2nd run(kicked sideways on the launch)
60' 2.213
330' 5.859
660' it says 4.789 but it was messed up because of leaves/debris
990' 11.409
1320' [email protected]

3rd run(best of the day except MPH)
60' 2.043
330' 5.679
660' [email protected]
990' messed up again
1320' [email protected]

where should i be shifting? I logged the max RPMS on the SAFC and it said i was shifting around 7300 and then on the 13.4 run i shifted at like 7500 and i ran faster...

edit: my car has very heavy bling bling 18'' wheels that came on the car

what are your boost controller settings? set?-gain?-set gain? at??? just curious

im assuming this on stock t25 turbo??? u will see much better results with a bigger turbo. 18's will slow u down too, just think of the rotating mass and how it affects things.

i think shift points on stock t25 are 1st 7500, 2nd 7200-7300, 3rd 7100, 4th at 6900-7000. thats if u wanna get into useable powerband. no need to redlining every gear.

yup stock turbo...your prolly right on the shift points...
