I went to WIR in Kaukauna tonight and got a new PB. The track prep sucked there and having 245/35/19s didnt help either. My first run was my best. I really need some DR's. I can't get sub 2.0 60's with these tires. My drag bags were at 18psi.

Timeslip 1:
RT: .325
60': 2.05
1/8: 8.37
MPH: 86.75
ET: 12.86
MPH: 108.74

I ran 13.02 @104.02 and 13.09 @ 109.27 on my other runs. On the 13.02 run I shifted into 4th at 6500rpms. On the other run I shifted into 4th at 6100rpms and got a higher trap speed. Can someone explain this?

If you want me to post the timeslips, just ask.

Heres the 13.09 run. I don't have the others. I always forget to turn my camera on!

So I'm assuming run #2 was the one you short shifted 4th?

Maybe on run #3 you hit the rev limiter in 3rd? Your 1/8 mile is cooking!

What was your shift points on the PB pass?

Does the LS2 hit peak HP at 6500rpm or closer to 6100rpm's. I never even checked. You may be onto something here:) Usually when you have a bad 60ft's the traps are higher, which is consistent here.

Either way Nice passes and traps..keep bringing them down!!

Yes, on run 2 I shifted to 4th at 6100 and run 3 at 6500. My redline is at 6700.

My shift points on my best pass were around 6300-6400. I was just experimenting with shift points and I thought this was weird.

Looks like the mph was off and that may have been a 110mph pass.
Which pass?

You cut a 1.8 60ft and you could run 12.4-12.5 . . .

I'll be ordering DR's next week. I think I'm going with 275/40/17 MT's. I canceled my BFG order. Then I'll be getting some 1.7-1.8s. 2.0's on 245/35/19s is all I can get.
