Default Dyno Numbers

Just had my stock 03 Z06 dynoed and got 413 to the crank and 350 to the wheels. Are those good baseline numbers?

How did you get Crank HP numbers? I doubt you had the motor pulled and ran on an engine dyno.

Your car is right on par for a stock ZO6 w/ 350RWHP.

Just wait until you install headers and gears...

That sounds on the high side of average, but right there.

On the Dyno sheet i think it was estimated horsepower to the flywheel or something i will have to look at it again or post it on the forum.

There is an easier way to do this. Most RWD cars with combustion engines have the same range of drive line losses. Generally, an automatic has a 20-22% driveline loss, while manuals have a 15%. Somone people have quoted only a 12% loss for a C5, which may seem a bit to conservative. But anyway, using his 15% loss, 350rwhp is equal to about 412 hp at the crank. Using a 12% loss is right near 400hp at the crank. But yeah, the 100% accurate way is to take the engine out completely and run it on an engine dyno.

It’s hard to judge dyno numbers done by different cars, on different days, on different dynos, and with different correction values. Without seeing a chart we are flying totally blind. Peak numbers are only part of the story. Some dyno runs have spikes that exaggerate the maximum output value. All in all I would say that 350 RWHP sounds like it is in the ballpark, maybe even a little low. The flywheel quote is meaningless unless you pulled the motor and put it on a dyno.

I know there is an engine dyno, but i just assumed that was an estimated number, but i guess not i will have to find out from the guy who did the dyno run and see what he has to say.

A guess at the crank without doubt. Was there tuning done, or just a dyno pull? For all we know, there could be alittle left on the table depending on where the A/F ratio was. ActionZO6, you should get a copy of the dyno sheet from the guy and post it here. It's all speculation at this point, so we can't tell you anything accurate.
