I am about to go to the track in 2 1/2 hours.
I have 17in slicks
I just wanted to know what kind of psi should I run
what should I launch at
also I know I will have to shift in 4th should I short shift 3rd?


btw stock clutch!

 

psi will be dependant on the tire. it should say

 

^ Like he said, it all depends on the slick and what it says

All people run very diff. setup's

 

they say no more then 35 psi

i was thinking of running 18psi at the track?
it is the ss/na with the 17in bike slick

 

you should be able to launch pretty high if ya wanted to. there was a guy that launched at 6500 with slicks on a lsj. but i would start low and go from there.

 

thanks but any one know what kind of psi ppl run in slicks i dont want to run to low at 15 or to much at 35

 

try 18.

 

^^thanks soccer

 

you don't want the tire to be flat per say. but you want it to have enough play to where it can start to wrinkle the sidewall upon launching. but on a 17" wheel idk how much side wall you have. thats why people tend to run the smallest wheel possible. brembos ftl lol

 

i am going to try 20 because i am on stock clutch. if things are going good i will drop it more idk I hope I get a 1.9 tonight

 

15 or so psi is good on that tire. Thats where I had good 60's at. I tried 12 to 18 and that seemed to be the best for me. If you are at a 7000 rpm redline, then leave it in third, the tires you got are 26 inches tall. Launch, ehh try 3000 see what it does if the clutch is good go to 3500. I left at 45-5000 on the stock clutch and all was good.

 

ok I cut a 1.90 60ft I was happy but in that run I missed 3rd
I had 2 1.9 and 2 2.0


wow slicks are great!! omg I need a few more passes its like a new car. my clutch never slipped. every run I would launch at different rpm's I found 4,500 to be the best. I also found it hard to use slicks with out a 2step or WOT box. I was only at 20psi but I still could not get them to spin.

next time I go I should get some good passes I had to sit in my car for almost 2 hours to wait out the rain.

 

20psi in the tires? or boost? lol

try lowering the tires down to 18 or 19. then start at 4,500 and up the rpms each time by 250 till you get them to spin. then back it off 250. and theres your setup every time. 18 or 19psi and XXXXrpm

i foresee low 1.8s happening.

 

yea it was 20psi in the tire I am not going to go any lower if I dont have to....I could not get them to spin I dumped it at 5000rpm thats when I got the 1.90......next time I will try around 5250.....its hard to keep it in the same spot I need a WOT box. also want to launch on boost

 

oh ****. for some reason i thought you had a WOT box. yeah after you get one of those you're going to need to lower pressure. 20psi is actually normally too much for most slicks. and if you're running a WOT and generating boost while trying to launch at 5k, may not hold.

 

so what was e.t's and traps??

 

I went
13.0133 at 108.70

idk why my mph is so low it seems like every one else hits 110
tonight is zzp's track night so I hope we can get a little fine tuning in

 

nice. knocking on the 12's!!
