just got m&h 8/22.0-13 slicks on some bogart rims....the question is what psi should i be running these things at to start with?

 

I would start at around 10-11psi and work your way down. depending on what axles your on. I run stock axles and the same slicks as you, I launch at 7 grand at 10psi in the slicks. I pulled consistent 1.7 60's spinning alittle bit. I haven't snapped an axle yet.

 

it also depends on how much power ur car makes , my buddie run's the same size on his turbo Ls hatch.. he's making 293 at the wheels and he runs around 7-8psi and still has trouble with traction i've seen people run 5-6 psi on there slick you're really gonna have to test out what will works best for your setup .. start higher than work your way down

 

What is the setup? Is it just the Civic Si like in your name or what? Give us more info and we can give you more info. But you just need to get experience on your own to really learn.

On my buddies 92 hatch and GSR motor we had the pressure at 12 on our local 1/8 mile and bogged a little bit while launching at 7000. We needed to take it up to probably 15-16 psi, but never got a chance.

I ran mine @ 10.5psi.(cold) and launched @ 5500 cutting 1.8 60's w/ an LS in an 89' SI hatch.

also, do nice burnouts, m&h's seem to love burnouts, and from what ive seen, after a burn out the psi goes up like 1-1.5psi

 

thanks for all the good info....when doing a burnout on slicks....does it matter which gear i do it in? ie: 1st or 2nd?

1st doesnt smoke em anywhere near as well as 2nd, i havnt tried 3rd

 

7psi perfect

 

I run the same size slicks and before the burnout I run it on 8psi. After the burnout it will be at 10psi. I Do second gear burnouts. It depends on how much power your car is making..
2nd gear burnout
