Hey guys..
This is something new to me, but i have a set of 275/40/17 MT DRs on stock aluminum 17s that i got for a really good deal..

They work great. But my buddy wants them for his Trans Am. and my other buddy wants the rims.

RanWalk has my other rims that i got from Element80 awhile back. My plan was to get some Slicks for them. They are the same rims that are on my truck.


So here is the big whopper..
You can see in my sig that i have the 80E, Stock converter, and 3.42s

Id like to get some 28x10.5?-16 Slicks so it wont look so goofy like the 26" DRs do.

I dont plan on driving these on the road at all, strictly track tire. Thats why i want a real slick.

Before i sell my buddy the 26" DRs i want to see what it runs in the 1/4 with them.. and see if i can Con Ranwalk into letting me borrow his 28" ET Streets and see which works better.


Im shifting at 5800-5900rpms.
With the 60E i ran a 13.3@102 and that was the bottom of 3rd.
Now with the 80E ive ran a 13.1 but didnt get a MPH.
Shifting into 3rd at ~95 with the 80E..


So somebody please shed some light on this, if you know what im tryin to get at..
26" vs 28"

The 26" will give you some good gear but i bet you will want the 28" for traction. were your runs on a 30.5"?

With a 28" tire you will trap better, but your 60ft will still suck and e/t won't be that great... A 3000 converter in that 80 will really help... I won't bring up swapping to a 3.73 gear, I know you won't give up those tall bastards

There's gotta be a compromise if you want a better slip... You will still keep good mileage too I'd bet.

My 13.3@102 was on Ranwalks 28" ET Street
My 13.1 was on my 26" MT DRs spraying the 50shot.


Maybe i should just find a 27" tire..

No stall for me.. you ever priced one of them things??? They are ridiculous. I can get 2500 brake stalling the stocker with my Toyos... Maybe i can get a lil more out of it with some slicks. prob up the shot just a lil too.. or the boost.. haha depends on if i can get my LC1 working before my injectors get here..

I dont see any gain coming from swapping to a 3.73 from a 3.42. thats alot of money i could put else where.

Your 60s would drop with a gear swap... 3.73s will still load that turbo fine with the stock converter, when your 60s drop, your e/t drops.

Yeah, I know a stall for an 80 is a good chunk of cash. I'd up the boost personally and consider a gear swap... Your kind of at that poing now.

FWIW, I'm debating on either a 28" or going with a 30x10.5x15 Hoosier full slick for my setup... I've got the rims, grinding the calipers wouldn't be bad. And that amount of sidewall should allow me to launch under some decent boost with my converter and still dead hook. But really looking at it, our setups are day and night.

i had opposite results...better 60' with the 28's and trapped the same MPH. the better 60' was due to the 26" et streets not hooking for me any more.

That's where the setup would differ... Taller tires will load the turbo a hair better IMO. I but what you're saying would be accurate if you were having problems with the 26s hooking.

How much better are the Hoosier's vs the ET streeets? YOu have one of the best 60's I have seen for a 2wd ECSB truck.

i think the extra sidewall of the 28" hoosiers is what made the most difference in hooking. the shor sidewall of the 26" was just too stiff at a certain point. im sure the 28X11.5 et streets would do the trick too.
