1 im running a 24.5 x 8 x 15 slick. would a smaller slick help me run a better time?
2 im running a 13.0 @106. im still spinning coming of the line an im running 8 psi in the slicks. thanks for your help

 

1. depends on your gears. you want to be at the top of fourth through the traps.

2. 24.5x8 should be plenty tire if you're only trapping 106. I'd look into dialing in your launch and suspension first.

 

What's your setup?

 

the 15" is murdering you.

 

a 15 is kinda the size im stuck with. I don't believe I can run a 13 on my car.

 

im actually just shifting into forth as I cross the line.

 

its a 94 accord ex full interior, Sleeved f22b1 single cam, I was told t70 turbo not 100% sure on size. running 15 lbs right now

 

Then yes, a smaller tire will make everything shorter overall, multiplying torque.

 

how much smaller then Derek? I don't want get to small and possibly over power tire when I turn up boost.

 

The right lane is my best time right now to date. I need to work on launching and I need anti lag bumped up alittle. This is leaving line at 6 psi

 

turn down the launch limiter rpm and are you running full boost in 1st gear ? Is the head built? Can you get more rpm out of it so you don't have to shift to 4th gear?

 

23"!

A customer of mine ("sleepinonacreeper" here on Honda-Tech) runs 23" tires on his 600whp K20 Civic, and has no problem making 10.2-10.5 @ 138-140mph passes without over-powering the tire.

The only problem with running 23" tires on your car would be finding a tire for a 15" wheel in that size.

 

M&H makes a 7.5" & 8.5" wide 23" slick for 15" wheels.

 

OK thanks derek

 

Yea I'm running full boost in 1st gear. Head is being built here directly and I can raise limiter a little more because I'm running it up to 7k right now.

 

Perfect!

 

I'm gonna have to look into these tires then. Thanks

 

I run the 23x 7.5 15" M&H and so far they have been great, only a few passes on them so far, but pulling a 1.7 60 ft on a track that is not very well prepped.

 

Are you all motor or forced induction

 

I ran 11.1 @ 130 on mh 23x8.5x15
That was at 430hp w no bbg

 

Spray, at that time it was only on a throttle switch so I sprayed once I was full throttle in all gears. Unfortunately I dont remember how far I was into fourth gear when I passed the 1320.

 

You shouldn't be using anything taller then a 22" slick
