I looked at my logs from tonight and on that pass I left at 7300rpms. So either the tires were not hot enough or 20psi in them was too much?? Either way I just need some more seat time and I will get them down to the 1.5-1.6's.. Any sugestions are welcome!

Im agree with zinx i never go up to 20 psi unless the track is hooking to good ive run 1.52 at 15 psi at 7800 launch.

when you blow the tires away, you're mph will generally be higher.......
20 psi on ET streets is what I keep in the tires for the drive to the track..........
I then drop them to 10-12 psi. I've tried 8 psi before, that was a wild ride on the big end.......

I went to the track for midnight drags sat with the street tires and with a blistering 2.04 60 ft i ran 7.81 in the 1/8 but 11.67 1/4 at 124.97 mph. On the et's i run 7.0 1/8 at about 100 mph. I was suprised at the trap speed on the street tires it was almost as fast as my 10.8 runs! Oh the clutch is fading fast i wish i had $1600 for a twin disc!!

Very good interesting thread. I suck at driving so it seems I can not get any better than a 2.0 60' in an Rx-7. My typical launch is 15 psi in old ET streets, but only 5-6000 rpm. At 15 psi boost and 400 rwhp, I've gone 8.0 @ 93 / 11.5 @ 124. I'm hoping that when I slightly improve the short time (maybe a higher rpm launch?), I'll be deep in the 7s / 10s.

Just kidding, you are probley slipping the clutch and getting a pretty good time. But when your running a higher h/p single turbo with out a twin disc slipping the clutch heats the clutch and causes slipping!

Again, a 1.8 and above is the norm for a good driver on street radials (not drag radials). I used to slip the clutch and pull these pretty regular. Now I am trying to dump the clutch (no slipping) at 7500rpm with 200 more whp..take some pratice.. Reason a ran a 2.36 was from the amount of wheels spin I had. Seems a 1.4-1.5 is good with ET streets. I thought is was pretty decent time for the worst 60 foot time ever posted on the internet! LOL

haha yeah, i dont worry about reaction times. I go when im good and ready stock base suspension with broken diff bushings and clunky pillowballs
actually on track with the thread, I have noticed that when i got a horrible launch (wheel hop) i would trap a little higher 85ish i guess because i spend more time on the track? so from what ive seen there is a little difference.

I am running JIC coilovers. Pretty damn stiff too. Not a drag set up at all. killer on the round track! All I did for the last day was soften up the rear damping and stiffen the front. I was thinking of lowering the height in back and softening up the preload as much as I can.
Think I have to go out of town this weekend so it will be the following before I can run again. I think tire presure is going to make a big differance as I just check them and they are at 22psi! So I imagine once I heated them up at the track they were close to 24psi!

Trial and error what works for one may not work for another! There are alot of varabiles!
Thats why racers rent tracks for testing and tunning chassis.
