Off the bottle with just 4.30s, O/R X, K&N, and 555Rs the best I could run was an 8.72 with a 1.92 60'. It is all going to depend on the track prep. You could drop the PSI in your Nittos to about 18 psi, and try launching from 2500 and working your way up.
At my track I usually cannot launch hard at all without spinning, but last week it was prepped really well and I was able to do a 5000 RPM clutch slip and spray in first and cut a 1.86 60'.
If the track won't hook, I'd worry more about mph than anything. I could never trap over 81 in the 1/8 mile, before or after my gears. If you can trap 81mph in the 1/8, you're doing pretty good.
N/A, I shift just before redline- sometimes I'll shift at 7000, sometimes 6600. Seems to pull best when I shift at about 6600 though. I leave like I'm leaving a stop light. If you dump the clutch you'll spin- I try to slip it quickly to get the best 60'.
Get out there and practice some more. Good luck.

Sounds good
I was shifting the car at 6000.You think higher???I also have a Steeda cai but it wont work with my proflow mass air meter not sure which works better.I guess I will have to practice.Should I shift same rpm into 3rd also????:shrug::shrug::shrug:

I shift mine at 6400 and my best time i launched at 5000... My car is x pipe, aluminum DS, 3.73s, a built rear and some suspension. BONE Stock motor except for K&N I went 8.64 at 81 W/ a 1.88 60' on Hoosiers at full wieght? I slowed down a bit when i shifted at 6000 rather than 6400, ran a couple 8.7s shifting at 6, bumped it up and ran 8.6s.
PS cant wait to see what it will do with nitrous and less wieght...

The track here in Orlando is not too bad. I launch at 2k and did a 8.4 @ 90mph off spray
These motors are made to rev, don't be sceard to take her up high. Good luck

your shifting way way to early, that right there is your first problem, go correct that and your times should change, then come back and we can talk on anything else that could be changed to help
I have never run a faster time short shifting.
Redline for me.
Redline for me.
9's in the 1/8th mile just seems really slow... You need to shift a decent amount higher, you are cutting yourself short.
