Default 1/4 mile rpm/mph with A4 and 4.10s?

Was wondering what you guys with A4 and 4.10s were turning in the quarter and what speed. 28 or 26 tire?

My car has a fti 4000 stall and Performabuilt level 2 4l60e. I'm not concerned with mpg or streetability. Only what it does in the quarter.

Not planning on nos. N/A only. Thanks!

My last Camaro ran a PB of 11.90@114. This was with a A4, 4.10's, on a 28 inch tall tire, bolt on's only. I'd go through the traps around 6200-6300.

My car with 26s and a 3.73 trapping 120 hits the stripe at 6500rpm or so. 28s dropped that down to maybe 6k so Im swapping a 4.10 to bring the rpm back up.

My goal is to run 10s on motor. Not going to spray. After the rear and coilovers I'll go with wheels, brakes, and then start on the engine. I'll probably put a cam and intake on while I decide what direction I'm going with the engine.

So I'm wondering with my goals in mind if I should plan on 28s?

My stock bottom end LT1 ran 11.0 flat at 122 mph. I was running a spooled S60 with 4.56 gear, 8" 5000 non lock up converter, non lock up 4L60E, on 28" tires. Check out the vids on sig.

So I'm wondering if 4.10s are too much with 26" tires?

How much power are you making? If near stock, 26" with 4.10's will be sufficient. If the car is making close to 400rwhp, I would try 28" tires at the track.

Right now it's 331 rwhp, but as soon as I get the rear end I'm doing h/c/i. Possibly rebuild the engine with forged pistons and rods. So I'm need to plan ahead vs where I'm at now.

Last year I was going the traps at around 7-7100 @ 124. That's 4l60e with 26" and 410's. This year I'm gonna spray so I'm going to a 28" tire. Gonna probably need to back the gear down to a 373 also to not bounce off the limiter. Don't think 2" taller tire alone is gonna get me 10-15 mph...

If you go with a tall 28 like a hoosier it might. Remember stock is only 25.5 or so.

1.47-1.52. Car has a problem shooting hard right on launch. Hoping I can find out what's going but I expect low 1.40's 60ft this year with better launch


Quick Reply: 1/4 mile rpm/mph with A4 and 4.10s?
