Guess my HP and torque - Going to a Chassis Dyno

Let's have a little fun

Guess my HP and torque at the rear wheels. I'm planning on a dyno session Saturday February 11th. The winner gets an item of MY choice from MY shop, Closest to the pin wins. Since the torque can be a bit questionable lets go off of Horse Power at the rear wheels instead.

Here's some information and if you need any more info. just let me know.

466CI

D1VE Block with Engine Systems 4-bolt splayed caps on 2,3 and 4. With Main Studs on all 5 caps. Screw in core plugs.

Eagle BBC H-Beam rods connected to domed BRC pistons 13:1 Compression Ratio

Canton FOX pan with Canton Windage Tray.

Ford 9 Rear with full spool and 4.30:1 gears.
31 Hoosier Drag Slicks


Should I set my tire pressure higher? Say 15psi instead of 8psi like at the track?

At what RPM should this engine peak? (Basically where should I set my shift light so I can take my BIG foot off the throttle :lol: )

He has a A/F monitor, what should I shoot for? 12.8:1 ?

Here's the dyon web site http://www.hoofnmotorsports.com/

The dyno is a Dynojet 224X model. It can handle up to 1000hp and torque at the wheels or 180mph. Can accommadate both front and rear wheel drive vehicles.

It is equipped with a wideband oxygen sensor to record realtime air/fuel readings for precise tuning.

Thanks!

You guys really think it will go that high? I'm hoping for 700HP at the flywheel which would be a lot less than 678 rwhp or 694 rwhp. Man I HOPE you guys are correct!!

I get 825fwhp and 660rwhp, the rpm's don't seem right coming in at 6250 for the shift and 6750 on the redline. I am sure it will be higher.

My 28x10 Hoosiers seemed to like around 12lbs. 15 seems a bit high.

9.87 @ 136 for 3400 pounds
