I went to the track last year with just Pacesetter Longtubes, O/R Mids, SLP LM1 CB, K&N CAI, Dyno Tune.... I ran a 12.9 @ 108 with a 2.1 60' on street tires.... But im a M6.... You have an A4 which has less power plus you have just a diablo tune which isint getting all the potential of your mods, So i would say maybe a 13.3 or so. But who knows it might be lower with a good 60'. Just my .02

A4's put less RWHP than M6's do to more drivetrain loss if you didnt know that!!!!

theres the important question. street tires youll prob run in the 13's somewhere. with some drag radials 12's are highly probable.

Kinda what I as thinkin.....high 12's/low 13's on DR's.....mid 13's with decent MPH on street tires

anybody have a clue WHERE he's running at? makes a big difference. with a decent (less than 1,000) he should be around 13 even with street tires

On Dr's high 12's or low 13's

im draggin at la rue in ohio...the track is not the best..very little traction...and i have 255 45 17s on the back..they are just my street tires..so i was thinkin i could prolly run high 13s..like 13.8 or 13.9...ad i was wonderin if any of u guys have 275s on the back of ur gto?bc i put some on and they rubbed really bad with more then 2 ppl in my car

I ran 13.5 @ 101 with just k&n cai but mines a m6
and I have 275's out back no rubbing at all but I am m6 sits up higher in the rear!

when mine was stock and i mean stocktune and all. the best i put down on street tires was a 13.8. but that was only once, but on average i ran a constant 14.0 and 14.1. now with my mods i cannot get enough traction to keep the tires from spinning even with the dr's...

first you have to worry about size more than "size". what i mean by that is that different manufacturers have different widths even when they may all be marked with the same "size". BFGs run really wide and Nittos run really narrow. that's why most of the guys that say they have 275s in the back are on Nittos or have their car jacked up like a 4x4. BFGs will be an inch wider. IMHO it's more important to have more rubber on the road than a bigger number on the side. you can however run BFG 275s in the back with no rubbing if you do it right. first you need the right wheels with the right width and offset. you'll also need to roll your fenders a bit.

by having my stock 17s widened an inch to 9" it not only provided a much better width for a wider tire but it also pulled the tire in more towards the center of the car away from the fender. i also replaced both rear inner and outer control arm bushing with poly to firm up any lateral squiggle. then by mildly rolling the fenders and putting on 5mm wheel spacers i was able to get 285/40/17 Firestone Wide Ovals (just slightly wider than BFG 275s) back there and can bottom out my springs without any rubbing.

275 Nitto DR's fit fine on the stock wheel. As said above, they run narrow than most tires. But it is a good drag radial that is fine for daily driving.

I'm now running 265 BFG's and they are wider than both the 275 Nitto's and Toyo's I've had on the car.

Just go to the track and find out..... Dont come back unless you have slips lol
