i have 4.10 in the car now. i was wanting to know how much going to 3.73. how much will this hurt my 1/4 mile time?

 

ill throw a ballpark figure out there of .1- .2

 

depends on what gear and RPM you are at at the traps right now.

 

105 at around 6100 rpm

 

I'll buy that 4.10 from you..

 

Let me know when you find out I am runniing the 3.73 now. I got only 8.05 so far this year from the car first time out also.

 

I run pretty close to the same set up you have in my Formula. I have a little bit bigger cam, lunati 00013lk .500/.515 plus 1.6 rks on top of that. I also run 28 in tall et streets. The best on mtr has been 12.68 at 107 and on a safe tune 100 shot 11.58 at 117.5. It only 60's in the 1.8's but pulls like a freight train in the last half of the track.

 

saturday made a pass with a 1.77 60ft and 12.940 1/4. but it would of been better if i had not shifted it at 4000 in to 2nd gear. but about 100 lbs heavier than last yr.

 

I went 7.81 with my son driving this past weekend. He is 14 and only weighs in at a mere 125 pounds. He drives like a veteran though. He won the 9.0 championship last year. We run down in Arkansas at George Ray's. So all we get is the time no 60' or anything. We hope to go to a better track soon as the water dries up some.
