I ran my car on the dyno yesterday, and netted 248.3HP at the wheels, and 316.2 at the crank.

The dyno has built in software that interpolated your run back to the crank using proprietary technology.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I ran my car on the dyno yesterday, and netted 248.3HP at the wheels, and 316.2 at the crank. The HP peak was right at redline, with a large spike at 5k and a smaller one at 6k. The dyno was a Dyno Dynamics, so I don't know how the results compare to the typical dynojet. Anyone know? Andy

POST 2Original post

Which model/engine? How did they calculate the crank hp?

POST 3Original post

The calcuolation implies 21.5% power loss thru the drivetrain. Does anyone know if that's correct? If rw hp is 248 and drivetrain losses are 20%, then engine hp calculates to 310. I'm not sure it matters since what you learned is your baseline for measuring benefit gained from future mods (on the same dyno).AS

POST 4Original post

No, 21.5 is excessive even w/ Dyno Dynamics. 911 driveline loss is more like 12%, might be 15% at the high. A tip car will come in at 15% mostly. Your 248.3 divided by .85 (15% loss) = 292.11 FWIW, we just dynoed a pal of mines 1999 C2 and got 261 @ the wheels on a Dyno Jet (his car has an air intake mod & ImagineAuto.com mufflers). For comparison I have my dyno sheet right here on my 1995 993: 241.7 @ the wheels. Just muffler mods on it. At 292 crank your just about right on target.

POST 5 / ORIGINAL POSTEROriginal post

It's the 3.6/320HP engine with the 6 speed. A '02 3.6 Tip put down 220 at the wheels, and mine only has a couple thousand miles, so I'm hoping for a couple more horses as it loosens up. Now that I think about it, the 964 manuals were only putting down about 170HP at the wheels, so I think the dyno is pretty conservative. The dyno has built in software that interpolated your run back to the crank using proprietary technology. It said 316.2 at the crank, so it's pretty close.

This is a source reference. Confirm exact model applicability in the original material.
