Looking for some info/advise on what is the practical limit hp and e.t. wise on a set of 22x8x15 m/t slicks? I searched and I saw that some people have gone low 11's high 10's on 22's but it seems they were all on 22x13. From what I have seen the quickest most people go on 22x15's is the mid 11's.

I was using the 22's last year with great results - 1.64 60ft's and a best of 11.71@117. Over the winter I found some more power but hadn't had a chance to go to the track till this weekend. I only got a total of three passes in and none of them had a 60ft better than 1.72. On all of them I was spinning off the line hard even with a lower than usual launch rpm. On one of them I was up against the limiter from right off the line till I shifted into second. Also I couldn't get a good burnout on them this year - the car would go right up against the limiter in second gear and not really smoke the tires at all. I was thinking about trying a 3rd gear burnout but don't think I have the power and don't want to hurt 3rd as its the weakest gear.

The car weighs ~2600lbs with driver and did go a new best of 11.65@117. If it was a turbo car I would try a gear based boost controller and just dial in the boost slower but its supercharged so I don't have that option. On my last pass of the weekend though I actually was spinning in third and fourth. Not sure if the track was just a little cold (it was a different day than the other two passes) or something got on the slicks. I looked at the tires/wheelwells after the pass but didn't see anything on them.

Sorry for the book but I just wanted to give some background information. If I could just slap on bigger slicks I would try them but I need to change the whole front end setup to go to smaller brakes to be able to go up in slick size. Also I am afraid bigger slicks will just cause the clutch to give up as its at its limit already. That and the gearing is pretty effective with the 22's so I would need to change the tranny to compensate for the larger slicks. I have no problem doing all this if needed but I don't want to go through all this work to run similar times.

 

i belive mike laskey was running low 10's on 22's when his white crx was black, and a street car. (i could be wrong though LOL)


IMO, get a larger tire to get some more traction, and make up the differance with a new final drive.

 

Lol his was one of the posts I found but were they 15's or 13's?

 

Bump
Nobody has any input on the practical limits of 15" 22's?

 

My car with 380whp a few years back would run consistent 1.6 60ft times and run 11.30's @122-125mph. I know the HDM Motorsports hatch was running like 10.2's on the same tire.

On a 15" 22? At what weight? I am not looking to be the fastest on 22's or anything I just want to know if there is more left in the setup before I swap to a larger slick. I am a big fan of maximizing a setup rather than just throwing parts at it. What sort of tire pressure were you running in them? I will probably be giving the 22's another chance or two but I am making the changes needed to at least try the 24's with my current gearing.

 

6.95 @ 211 mph.
