Thread: how to knock a 1/2 second off my et

Tweet

too many questions not enough computer time
don some spin with the tires aired down, tire spin out approx 150 to 200 feet off the line with tires at normal pressur(darned scary)
our timing syst has no reaction or 60 ft but for an example i raced a chev pickup with slicks and a strong 406 a couple of times(consistent 13.5 truck) he would holeshot me but i would start to catch up after the 1/8.makes me think there is more there.
last run 14,1 and close to 100 mph
starting line rpm 800 and punch it- if i load up much more against the trans then the spinning gets way worse. welcome to a high tourque engine
i know that a good set of slicks would probably bring me there and beyond from what i have seen but i was 1st goign to play with the chassis before i go any further re tires.
i do agree with stu though i think taller tire may be a good start as i have 31 inch street tires and it makes it launch on the street better. i was running just little 26 inch tires on the track
this is all just bench racing as i do think if i went and got a good set of 10 or 12 by 31 slicks and a higher stall convertor from stock that 13.5 would be there and gone easily.

Sounds to me like the launch is where you need to beef it up a little, especially when you say once the car starts moving it was catching the other guy. Those Caddys are torque monsters, so you need to take advantage of that.

If you can borrow someones slicks, try that. I agree with the guys about the taller tire size too. At 800 rpms you are just idling off the line, slicks will allow you to launch it harder.

Another thing that will sound dumb, but you want to make sure your carb is opening all the way. After I got my 5.0 in my Jeep I found out after driving it for a few months the carb was only coming open 3/4 when floored. I set up the linkage all alone, and had nobody there to stomp on the pedal while I looked at the carb. What a difference that extra 1/4 made.


Hey, you're having fun.........that's the real importand thing here, and you are out there on the track, where most guys never actually go.
