2 tenths in 60 nets 1 tenth in 1/4 ?
Put the new BFG DR's on, 225-50 15 with small
diameter so as not to ruin my gear ratio. They hooked good cutting my 60 from 2.27 (14.52 @ 96.24) to 2.0x for three runs;
14.44 @ 93.5, 14.63 @ 92.77, and 14.76 @ 94.06. I thought better short times were
supposed to result in much better 1/4's ?
Car was not changed at all from the 14.52 run in Aug to these runs. I must have put a
whole 80-90 miles on the car between the two times at the track so car variables are
small and the car did run good. Only thing
I can think of is the drag difference in the rear tires with the street tires run at 35
psi and the DR's at 23. Also my friends LS1
2000 Corvette ran for the first time and had
3 runs with 100.xx mph for top speed which seems rather low. Maybe weather conditions
(pressure and humidity). This Sat was unseasonably warm in the northeast.

I guess I'll anwser my own question. Is was the weather! Went the next weekend with no changes and went 14.20 @ 96.74, 2.02 60 ft, and it was about 45 degrees. Time to change the signature....

Normally, the rule is a tenth picked up on the 60' is worth 2 tenths on the long end. I has held pretty close to true for me.

Genereally the one at the bottom equals two at the top addage is true if the car has no problem with top end power.
Sometimes it takes a while to get it to hook and not bog.

if it don't sound like Micheal Bolton your alright"
