Default 4.10 gear and 26" tall tires on an A4....not enough gear?

4l60e
4.10 gears
26" tires
3600 lb car
450-500 hp with a 150 shot on top of it, so figure 600 hp
233/240 .618/.589 LSA111+3
4000 stall

Taking into account converter slippage, will this setup shift into 4th in the 1/4th?

If so change tires to 28, gear, both?

That's gonna be real close. At 6800 you'll be around 128-130 mph in 3rd, so with converter slippage it's gonna probably be tight. You've never ran your current setup?

Not on bottle. Guess I'm putting 28's on.

Is your converter able to lockup at wot? If not you'll need more tire.
At 6800 rpm with 5% converter slip (which is very efficient) that's 122 mph. Locked at 6800 I calculated 128.
Not sure how efficient or well built your converter is.

get the 28's. Unless you have some suspension work done your gonna have a real hard time hooking if you spray outta the hole,
