I finally got my upgrades installed on a 01 A4. It dynoed 402 RW. What would that equate to the crank?
By the way, my mods were: H/C, ported and polished T/B and MAF, CAI, LT headers, x-pipe, no cats, BB bullets quad tip, and tunned.
I can now finally call my daily driver a KLRBEE (01 yellow CPE).

Crank HP

I always add 15% to the dyno number for a manual - 17% for auto. In your case that should add approximately 60 HP to your dyno number if its manual and 68 if its auto . I've been told it also depends on the type of dyno used for the reading. Good numbers :cheers:

You're looking at about 470 at the Crank. 470 minus 15 percent = 400 rwhp.
Sounds sweet Bro :thumbsup:

Thanx for the replies! Now I need to be able to put it down to the pavement. I tracked it this wknd and could not hook. My best (aweful) 60' was 2.2 and I turned 12.8 @ 111 mph. I'll need to work on my driving skills or spend the $ for some dr's.

There is a formula to calculate HP rorm Flywheel to Rear wheel or vice a versa. I believe you divide your HP by .88 for Auto and .82 for 6 speed.


Here's the formula....

Manual trans divide RWHP by .88

Auto trans divide RWHP by .82

2000 corvett, my cam is a 212/[email protected], small cam, great mid to high range power. Blown Z, that formula seems a little high to me, I don't know. So you are saying that in my A4 that puts 402 to the wheels, I have 490 to the crank? I was told more like 465-470 to the crank, adding a 15-16 to it. Which one makes more sense?

Thanx!

That formula is on my dyno sheet form Texas speed. Not sure how accurate it is, it might be accurate for the type of dyno they use?

Did you get a "Before" dyno run?

If you did, you should try dividing your pre mods dyno'd rwh by the posted hp for the stock engine. I know that there is some variation between each stock engine, but it should give you an idea of % power difference between the crank and rear wheels.
