It looks like I might finally get to try out the 3600 stall tomorrow night and I was wondering if anyone could tell me what psi I should start out with on these 275 40 17 hoosier drs? Car just has minor boltons in sig and ss3600 stall. Last year when I used them I only had stock stall and I was able to get away with psi at 28-30 "or so"

The higher the better. I would start around 20psi and work down if it doesn't hook.

I did some searching and it looks like some guys will start at mid 20s? What do you think I should be starting out at? Im not making a ton of power like alot of you guys.

Thats the thing, your going to get a range of opinions. Most should fall between 17ish to 25's. I always voted for as MUCH as you can before you start spinning. Track and prep conidtions will influence this.

I would say try 21 and record the data, if its not good enough and you spun a little, take some air out, if it bogged, add some and see how the car reacts.

Being a auto car you should be with in 1-2 tenths of your best/average time generally so its going to be a case of fine tuning.

I started at 23psi to get a feel for the Hoosiers.

By my 4th pass I was down to 18psi and still couldn't hook.

My best 60ft on 6 runs was 2.009 my worst was 2.066 which was my best slip.

BTW mine are 255/50/16 Hoosir DR's.

I went right to 17psi, dead hook everytime but mine are 15s

Another vote for 17 psi, even though they are 17's. You want those sidewalls to flex. Unless you want to waste some runs. Remember, every wasted run includes a wasted burnout and money up in smoke.

Any time I have tried over 20 psi with any size drag radial, I have spun. Also, any time I have not done a burnout with at least 5 sec. of good smoke I have spun.
