Mods, please move if I'm retarded.

I know that there is a mathematical way to figure this out, but I don't know it, I don't want to know it, and I don't care if you know it. I just want a straight up answer.

Setup: D16z6, tt rods, srp pistons, acl bearings, GE block guard, t3/t4 .57 trim .60/.63 ar, Tial 38MM at 15lbs (willing to go to 19-20 at the track), LSD extreme 6 puck sprung clutch, stock Z6 tranny, stock Z6 axles, I may be putting in a cheapo LSD in the future, but right now I'm stock. I'm looking to be sitting comfortably in the 11's in the 1/4.

I'm going to be running Lensos and I just need to decide if I should get 22x8x13 or 24.5x8.5x13 slicks. Someone here knows.

You have two ways you can go about it:

1) Tell me vehicle weight, revlimit, and estimated horsepower. All I do is play around on a tire size calculator until your estimated trap speed matches up with mph @ redline in 4th gear.

2) Ask Dr. Boost what tires he runs on his Jeep, because nothing launches harder, nig nog.

id say go with the 22's. d seires trannies have long gears and they dont make a ---- ton of power like b series. assuming your revving to 7200 (stock) the 22's will put you at about 122MPH at the top of 4th.

Z6 tranny with CRX 4th gear on 22's runs 11's 2-3 years ago......

Civic_Tsi, you might have seen the video.....where you think the 4th gear came from?

Darkelvis

vehicle weight will be around 2000ish (w/ me), redline at 7900, hoping for 300-330 hp......

So, I'm lookin at 22s as of now huh?

Last year i ran 23" slicks with about 330ish. I couldnt go anyfaster in 4th traping at 121@8,000RPMS

Ill be buying 24.5" sometime next season

Darkelvis

and that is exactly what I'm afraid of.

330 whp in 2000 lbs = 128-132 mph. With the higher rev limit you can get away with the 22's but IMO go 23's. By the time you wear those out you'll probably be cranking boost on racegas and ready for 24.5's.

Trade you my Never been spun M/T 24.5x9x13 With Areo Rims for a set of 23"s

trust me ur going to want 24.5" i have 23" M&H's they were pretty good but i could have went faster on 24.5"
