I'm certain the heat was a factor in these times and I can't lie, my buddy ran these posted times. My times were 14.0. We had some problems with the clutch sticking in the first couple of runs. We let it cool down, stopped doing burn outs at the start, and launched below 2,000rpms. Raced two 5.0's, GTO, and a turbo neon and beat them all except for a hopped up 5.0.

Anyone have advise on when to rev/shifts each gear?

I can't wait to get back stateside. As soon as I do, I will be coming back to Sarasota to visit family. Spent many a night at Desoto Speedway and at the drag strip next door when I lived there years ago. Maybe I'll see you out there?

You had some sub 2.0 60' times. That should be good enough to get you around a 13.3 - 13.6 with the rest, i'm sure the heat played a factor.. Were you keeping your hood open and blasting the heat inbetween runs?

i went to the track today to 94deg. hot as hell.. best was 13.73 with a 2.1 60ft and 103mph.

Are you getting any tire spin? Try lowering your tire pressure.

You're 6MT I assume. What are you shifting at?

Being that the clutch kinda overheated to start we stopped pre-run burnouts and launched the car at relatively low RPM's (1,800-2,000 maybe) and lowered the rear tire pressure to around 30 psi.

I am assuming by the decent numbers we had through 60' yet slow trap speed and ET that without any wheel spin off the launch we are losing tenths of a second and speed around the 1/8 mile mark and continuing down the track. I noticed that our low end numbers compared to the others on this site; if not better, yet we are still running high 13's and just eclipsing the 100mph mark through the trap.

Long story short, (too late!) do we need to "pop" the clutch at the tree, maybe sacrificing some of the 60' times to gain better speed through the 1/8th for a better 1/4 time and speed? Thanks, any input would be helpful and truth be told, I have no idea what RPM's I was shifting at, I just listened to the car and shifted when it felt right. This was my 1st run in my buddy's Z and had only driven the car for about 30 minutes prior to getting to the track. I have had experience in running the early 90's 5.0 and 6 speed LT-1 Z-28's and Formula Firebirds. Recently I leased a G-35 auto, but the 6 speed 370 is a straight up beast! Hats off to Nissan for hitting this one out of the park...my Acura CL-S 6 speed feels like a Buick after driving the 370

We probably did 12 runs the temp never breached 230. We had problems with the clutch in the beginning when we were popping the clutch in first gear at the start. The clutch stuck on us twice which returned us a 19sec and 34sec 1/4 mile, awesome! It made me sick. I thought I was going to have to replace the clutch after owning the car for only 3 months. We almost called it a day, but we let the clutch cool down and started running again without taching up at the tree. That's when we started running in the 13.9's and 13. I think I need to figure out how to tach up in 1st without the clutch sticking. Wheel hop is another issue if the clutch engages. Thanks for your comment.

Nice run, I haven't finished over 101mph yet. Still trying to figure the car out. How do you like your Berk Cat? Do you notice a performance difference?

That translates to 280 HP at the wheels assuming curb weight is 3278 lbs + 180 lb driver.

For your best run above:

That translates to 272 HP at the wheels assuming curb weight is 3278 lbs + 180 lb driver.

Neglecting skill of the driver of course :)

+225lb driver

I love the berks, really has opened it up. Its hard to get traction though.. i need some slicks!

Fat boy (lol)

I'm 6'2"....what's your excuse 5'9"? (lol)
