Stock i was 306 hp
Turbo16lbs was 317
04blackc32 was 307

But this was in south florida with warm temperatures and high humidity. Keep in mind, these cars perform better with every dyno. So your third run will be your best.

Place off the 5/605 freeway. I went with a local car forum and we got 3 runs for $45.

I'll have to keep my eye out for a 32

So, my question is, is the driveline in the C55 super efficient, or is the motor actually making more than the rated 362hp?

I typically use 20% as a good driveline loss figure for an automatic. At that percentage, your rwhp would be 290. With your number, and using 362 flywheel hp, driveline loss would be only 14.5%, which is extremely efficient. Or, with 312rwhp and 20% driveline loss, your car is actually making 390hp at the crank.

Anyone have any insight into this?

Bill

His car would be making roughly 375 crank horsepower using the standard 20% loss estimate for a car with an automatic transmission. Not sure where you got 390 from?

312rwhp divided by 0.8 = 390hp at the crank.

Doing it the other way, 390hp at the crank x 0.8 = 312rwhp.

I was under the assumption that 1.2 x 312 = 374.4 was more accurate. To verify:

0.2 x 312 = 62.4

62.4 + 312 = 374.4

i agree with hlg600 multiplying by 1.2 is more accurate. Dividing by .8 is the same as multiplying by its recepical of 5/4 = 1.25

(312 / (8/10) ) = 312 * (5/4)

so your adding 25% not 20%

Figure 15% on RWD/FWD, 20% with AWD and I've been "close" most of the time (as another poster stated-diff dynos will show diff #'s)-good work on the #'s-is it bone stock (oil and all?)-thats good news for us newbies looking to mod.

i would say fwd would be closer to 15% then rwd. There's more drivetrain lost rwd because of the transaxle. awd for obvious reasons.

My formulas are correct and are the industry standard. Trust me--I owned and operated a Dynojet for almost 8 years.

rwhp / 0.80 = estimated flywheel hp with an automatic.
rwhp / 0.85 = estimated flywheel hp with a manual.

-or-

Rated flywheel hp x .80 = estimated rwhp with an automatic.
Rated flywheel hp x .85 = estimated rwhp with a manual.
