That is probably an overestimation.

I tested out that calculator. It's pretty close IMO. It looks to be 50rwhp overestimating.

3600 lbs raceweight, with good traction (1.4X 60' times), you should need about 490-500 rwhp for your A4 car. 6-speeds at that weight would need about 515-525 rwhp, with the same 1.4X 60' times.

jason ran 10.50 with 1.4x 60ft. with 460rwhp at 3350.
i ran 12.2 with 3600 lbs and 1.8 60ft. with 350 rwhp.
acording to the caluclator i should be running 13.40's

According to the calc 610rwhp for a 10.52. Wow, I think a bit over is an understatement.

Don't blame the calculator if you don't know how to use it.

I put in 3600 @ 350 RWHP and got 12.6.

That doesn't seem that far off considering.

Holy crap, according to that, before my headers I had either 298 or 324 hp.
298 based on quarter mile time and 324 based on mph...which is more accurate?

Go by mph, it is the most accurate.
