Flogged the motor on the dyno today

My little N/A SBC spent the day on the dyno 1.83 hp/ci isnt too shabby. It ended up making just shy of 744hp and 587 lbft. We played with all kinds of stuff: ignition timing, jetting, valve lash, cam timing. Funny part is ya want to know what picked up the most power and tq? 14lbft and over 12hp from a simple piece of duct tape :shock:

We kept tightening the screw on my vacuum relief for the vacuum pump and finally just decided to tape the inlet shut. We got done with the pull and the guy running the dyno was like :shock:

WTF? Looking at the sheets it added about 8" of vacuum which is where the power came from.

Here is the sheet

How much do you think it will pick up this season?

I think we found an honest 20hp tweaking things I am guessing it may pickup a tenth or so. i cant make it too much faster I am lifting at 1000' to run 10.0s in R/S as it is :shock:

Craig, sounds like it's time to step up a class...

That'll be nice to shift the car at 6,500 and still run 10.00, the engine will last forever.

I tried that Dogg it doesn't slow down a ton. I even was shifting it first to third one weekend last season when I broke the trans. It still went 9.89 :shock:

with no 2nd gear

Put some 9" slicks on, or better yet put some Road Huggers on it and start bragging about it, :lol:
