Default Opinions wanted

Made this run last year after my T5 swap, it was my PB at a 12.4@108, 1.66 60ft. I'm alittle soft on the launch because car still has stock axles. I'm running 3:55's which put me on the limiter 100ft before the traps, so I started short shifting 4th which brought my mph up from 105 to 108. How much would 3:73's help? Click on link above screen shot, better quality video. And no comments on the squeaky window lol.




Edit: why isn't this working? I cut and pasted 3 times now. And it worked on my other thread. Or search "88 Mustang 1/4 pass" on Youtube. Sorry

What rear tire?

Your crossing the line in what gear and RPM?

What is the rear suspension set up?

26×8 ET Drags, short shifting 4th maybe 150ft before the traps, rpm is not known because I only made 3 passes this way and never looked, before I was bouncing off the rev limiter in 3rd at 6100rpm, and stock upper and lowers but lowered 2". There is almost no weight transfer.

And thanks to whoever fixed my link.

IMO you're looking at a good 2, maybe 3 mph gain with 3.73s. You are barely getting into 4th and really need a lot more RPM crossing the line I'm sure. I would go with 4.10s if it were me, unless you are planning on pushing a lot more power in the near future.

Can u raise the limiter?


You could try a 28" tire first before swapping gears

I think the most I'd go is 3:73's, just because its my everyday driver when it's nice out. I can't imagine 1st gear would be good for anything with 4:10's. But if you think I'll gain that much with the 3:73's, I'll do it.

My dyno run showed peak power at 5950, so I set the limiter for alittle overrev at 6100. Maybe I'll try that, good idea. I'm still playing with shift points, I have 3 tachs in car, (stock,Autometer, and Anderson PMS handheld) none of them match. Sometimes 400 rpm difference between them. I'm trusting my Autometer more than the stock.

As for tire size, I have a new set of 28×10.5's ET Streets that I tried, they worked good on a flat road but fender lip cut them on a driveway approach. They are just a hair too wide with the car being lowered.

Right now my top priorities are upgrading the axles and bumping up injectors to 24's, the 19's are maxed out. So I can't make anymore runs till then.

maybe a 275/60/15 radial (or = slick) would work. The taller tire and higher RPM on the limiter likely gets you thru the stripe in 3rd.

Thanks, that may work for me.

After watching video again, are my shifts alittle on the slow side? I thought I was was pretty fast during the run, but now I'm thinking "why so slow". This was just a used T5 I threw in, with a no-name short throw.

shifting seems fine to me, only thing I could suggest to change is to not let off the go pedal , pound the power shift.

Lol, yeah I thought about trying that on one " sphincter tighting " run. But I'd like this tranny to last alittle while. I've read that that's the killer of these trannys. Well ……… maybe one run won't hurt. lol
