I'm looking to see what others are crossing the 1320 at with either a stock FD or a 4.11, and if you use a 4.11, what are your 60'? I read that you can get better than a 1.6 60' if you have a 26" tire.

I'm looking for high nines, staying under 9000rpm, and using my qtp 26"/ fd combo full weight. If I can get away with stock gearing, I'd like that as it's just one more part I'd have to buy. If I stay stock gearing, would I benefit from an evo 9 1st gear?

Thanks for any info

 

don't know if stock gearing will be enough, but I can say for damn sure that on a 26" tire you'll be way below your RPM limit on 4.11

 

Ya I heard 60' would suffer on a 26" tire and a 4.11. I guess I'm looking to see what mph equals what rpm in the 1/4 with a stock FD. Like 140=8xxx rpms, 150=8xxx rpms, etc.

I'm looking for high 9s full weight on a 2.2l 6466

 

I'd love to help more, but I only ran a 26" tire once. It was a 9 sec run, lol, but I wasn't paying attention to rpm or anything on that run.

on a 2.2L i bet you're good with stock FD with 26" tire up to 155mph, you can rev. I played it safe for the 2.4L.

But, I'm sure guys with more experience on 26" tires will get in here and help you when normal people are awake.

 

I did a 1.59 60ft on 4.11+26" tire.

Variables: 2.4L, I had no 2-step, first time on QTPs

I'm no expert but I think 1.4 is doable on 4.11/26" tire, vehicle weight might hurt it some

 

Thanks for the info, I appreciate it. I am full weight pretty much (3200lbs).

So, stock FD I'm guessing on a 26" tire I would be crossing around 8700 with a 140mph speed?

About 8500 with the 4.11 final drive should give you enough MPH for high 9's assuming a good 60 and driver.

 

Good thread on it https://www.evolutionm.net/forums/dr...shift-5th.html

 

Thanks guys I decided to stay stock fd and an evo 9 1st gear instead. High 9s here we come

 

I'm on QTP's with stock gearing but I'm not stock weight. 1.62 60ft with 149 being my highest trap around 8700 rpm. Sitting on the limiter a good second before going through the traps.

 

Thanks for the real world info man. I figured I'd save some coin and go with the stock fd for this year. And I built my 2.2 to rev up to 9k-9500rpms so I figure it can handle it for now.

Thanks

 

I think 9k would be right at the trap beams on stock FD with 26". I'll let you know in a couple months lol

 

What clutch will you be using at that rpm?

 

QM 8 leg with a higher tq. capacity pressure plate.
