high 600s/low 700s seems to be the norm on other internetz boardz

I did see a video from Hennessy stating 708 rwhp, bit it provided no specifics, such as fuel used, if using standard adjustments for temp, humidity etc. plus they ran with hood open and blower.

ah yes...but they are all over youtube!

I’m going to Dyno mine. Maybe in two weeks.

Please share results! Are you stock? The old assumption of deducting a15% driveline loss seems a bit high. Unless Ford is under rating our power, if we use a10% loss, we are looking at about 684.

Ford has traditionally been conservative with the power numbers.

My 03 Cobra put down 402rwhp (SAE smoothing 5) bone stock vs 390 crank as advertised.

100% stock.

100% stock 100 miles 645rwhp Dynojet SAE corrected

100% stock 100 miles 645rwhp Dynojet SAE corrected

That is almost exactly 15% drivetrain loss.

I have not dynoed mine yet however, as others said, they are fairly consistent at higth 600's to low 700's. Of course, altitude/temp/type of dyno etc... all play a factor.

Plenty of videos all over youtube and if you look at the stock 1/4 miles times, 130+ mph traps are in the 700RWHP area. I had a 97 Supra that I upgraded to a single turbo, it put down 722RWHP on mild boost and it trapped 128/130mph at the track (6-speed), so the numbers align to what I have seen.

I had mine on the dyno back in December for a couple of baseline line. Pull took place in Albuquerque (@ DynoEdge) where the altitude is 5312’ and had to make a 100 mile trip to get there. The car was a ‘little’ warm when we did the pulls.

Erolivas- thanks for posting -do you know if the pulls were made in fourth gear ?

No problem. Yes those pulls were in 4th gear.

Wow, so far what I am seeing are 4th gear pulls with hp from a low of 645 to a high of 708 with SAE correction.. DIscrepancies, I am guessing are individual Dyno differences. Wonder if fueling makes up some of the differnce. For example, the 760 claim is only using 93 octane, but most of the country only has 91, so the computer could be pulling some timing. Any other variables to a count for the differences?
