However, engine Dynos are not very comparable from one brand or set up to another.

I have seen engine Dynos vary as much as 20%

An engine with the specs you posted would dominate various &quot;class&quot; racing venues.

I am curious as to the racing applications your engines have been used and your results against the competition.

Again, very impressive numbers!

Its always interesting when people start talking about dyno numbers. Myself I've never seen Super Flow dyno FWHP numbers vary much at all when the same corrections (STP) are being applied and the dyno is &quot;calibrated&quot; and the right inputs are being used. And to back up my opinions on here: 3 different times, my engines tested on my own Super Flow 901 with the TQ system checked and verified by Harold Bettes were shipped to: Reher Morrisson, Owens in Houston, and Westec in California, Super Flow sent their own people to calibrate Westecs dyno prior to my test, the results......less than 1 percent HP on the dyno's calibrated by Super Flow, Reher Morrison was high by 2 percent. Real back to back testing.

Mark to be honest my own engine, before I bought it had quite the difference from this dyno to Steve Schmit's. Made about 7% more on Steve's dyno then here. This dyno has been considered fairly close when went from here, to s certain, well know SuperStock dyno. A couple percent changes over the 3.

Can you post up the Steve Schmidt dyno test, thanks.

Sorry Mark. that was many many YEARS ago when my motor I posted that has a V.E. just s tickle over 120. It wasn't my motor, but it did run and qualify in NHRA Pro Stock.

Story I got is this:

&quot;One weekend while running P/S, there was a rain out. The team (shop I deal with) were chatting, and trying to get better running in the class (as they usually qualified around 10/14th. They were and ARE close friends with guys like Ray Franks and Dick Maskins, and even stayed at there houses during trips). So the topic of how much power they were making came up. Steve says &quot;were close to my shop and lets see why your so down on power, but still qualifying&quot;? They loaded up the cars and went to Steve's shop. Steve put his motor on, and told him it would make X amount of power, WHICH IT DID. That was about 7% more then they made back home on Fj Smith's dyno. So then then dyno'd my motor. IT MADE 6HP MORE THEN STEVE'S MOTOR AND MAGICALLY GAINED THE 7% THAT THEY LOST! The group concluded that it WASN'T the motor that was down, but losing it in the chassis.&quot;

We always get a laugh out of this story ad say &quot;THAT'S THE CANADIAN CONVERSION on Hp going over the boarder&quot;, like currency!

They came back and immediately went to BOTH Fj Smith's dyno, and IHRA Pro Stock racers Konigshofer's dyno and were back to losing about 7%.

So YES, the first dyno sheet is of my Pro Stock motor that the shop built on there own.

And when people like to ask questions. Myself, my crew chief and crew have some pretty wild ALL MOTOR cars.
-IHRA event winning Pro Stock
2015 NHRA Pro Stock
-current Aussie Pro Stock 399
-record setting SB ALL MOTOR cars
AND I believe the worlds fast SB Ford as well.

This is myself and my 4 friends. So we got a bit of a handle on some things. As many know, there's alot more to running fast that motor and Hp/tq!!!
