I have 22 slicks m/t on lensos wheels with 18k springs rate in the back and my best time in 60 foot are 2.0 with 9psi pression in tires launching at 7000 rpm allmotor thanks and looking for 1.7-1.8 60 foots thanks for help

 

drop the tire pressure .5psi at a time. see how the 60fts change with each drop. When you get your desired 60ft, (possibly around 7.5psi), keep it at that. Dont drop it too low if its not necessary. Its about finding that sweet spot where it hooks how you want it to.

 

thanks i gonna try that

 

Are you launching on a 2-step or just free reving, how fast does your car go in the 1/4?

 

launching at 7200 ran 13.4 @ 101 mph

 

Do you have a Full Race traction bar ?

What do you have for engine mounts ?

Is this a race only car or a DD ?

 

yes i have traction bar,hasports,race only

 

You are 2-step or free rev? Are you spinning off the line? I ran 13.0@104 with 1.7 60ft all motor launching at 5000rpm and it launched like a dream - preload and let it go
