Pony up, boyz!So was there a number before it left?
Indeed there was.

114.5 hp . . . at 9,500 RPM.
9,500 rpm is where the dyno stopped moving water.
Essentially, we turned a SuperFlow 902 into a Waring Blender.
We're thinking it's a 125 hp engine, but the dyno simply isn't capable of providing water at this RPM and providing reliable results.
Here's a printout of our last few reliable pulls -

I'll point out a few things here - at least as I understand them. I'm certain Mark will join in when his ears stop ringing.
Note the torque curve - it hovers between 63 and 67 ft lbs from 6,300 to 9,500 rpm, and was showing no indications of rolling off any time soon.
Horsepower, of course, is a function of torque and revs - and as long as the torque remains constant or doesn't fall off, as the revs climb, so does the hp.
So what does this mean for our attempt this year? Well, let's look at what's worked in the past. Mark superimposed the Grenade graph onto the K graph -

We tested in a much narrower range with the old A-Series, and it gave a LOT more torque below 7,000 AND better power numbers - UNTIL 7,800 RPM. That's where air flow and electronic fuel injection start to really show their mettle.
We set the rev limiter at 10,000. It appears that the way we'll need to drive this thing is to just simply wring it out in the lower gears and hope 4th doesn't drop us below what the A-series gave us - the 3-4 is right there in that pocket where the two engines power curves cross.
THANK YOU FOR LETTING US SHARE THIS - it was both frustrating and fun, gut-wrenching and stress relieving.
And hopefully a financial help to our favorite site on the web!
