What will it make on the dyno?

[BruceH]

Taking guesses on what my motor will make in rwhp and rwtq. The motor is a Big Bore Boss with 3.701 bore and 3.750 stroke displacing 322 cubic inches. Compression is 12:1. The cams are basically 127500 with 113 lsa and the icl is at 108 which is 6 degrees retarded when compared to a regular 127500.

Previous E85 numbers while na were 437/388. A Department of Boost GT500 kit has been added. The supercharger is a M122. It makes 7psi with a 3" pulley. There is also a 2.65" pulley that hasn't been used yet. It's revved to 7000 rpm.

The plan is to run this tank of E85 out, refill with E85 and dyno. The dyno will be a Dynojet that I've used previously. It reads neither high or low and is consistant with other Dynojets I've been on.

The dynos will be with the 3" and 2.65" pulleys. Guess rwhp and rwtq for both. Just to make it a little more fun I have a prize for the winner.

A list of the guesses will be kept on the next post. The dyno should be done within the next 3 weeks.

Good luck!

I love bench racing

The boredom overtook me last night. Might as well do something to break it up. I did manage to get a set of M&H 275/50/17 DRs mounted up and installed last weekend. Now I need to get to the track on a good day.

With that said we aren't guessing times or trap speeds, just power.

just guessing to make it fun. Good luck Bruce!

That's the whole idea.

what does the winner get for guessing correctly?

Just something to make it interesting. I have quite a few spare parts in the garage, it will be mod motor related.
