Guess the hp and torque (ord gift card)

It will be on a dyno jet. Last time it was on a dyno which was with the first engine and cam setup which was small it hit close to 300

Same dyno? Same wheels/tires? Same exhaust?

Some dynojets have load control, some don't.

I have seen just a tire change move the reading 70 HP, my truck, same day, same every single other thing, just swapped wheels/tires and made another pull....lost 70 hp.

Changing from high range to low range only changed 10 hp at almost double the ratio, so it's not gearing.

I think its the tire/wheel weight, but I can't be sure. They are basing their power calculations on how fast you accelerate a drum with a given weight/rotational inertia, and a heavy tire skews that calculation. The can likely store the electrical energy and release it as heat with load control, which loads it more and takes energy from the drum as well. This helps as they can measure the energy output too from the load control.

A hub dyno eliminates the weight of the wheel/tire as a variance. Obviously you still have the converter, trans, gearing, etc...

A true electrical dyno would take way too much electricity to run it. A 30A 230 V circuit is only about 9 or 10 HP worth of electricity, can't hold much back with that.

I hope its the same dyno, that would be interesting.

Have fun with it! And don't be disappointed whatever it is, like I said, the tire may make a larger difference in the reading than your cam swap. So its not really a true number, just for comparison on that dyno only.

Different dyno, same exhaust and tires but now doesnt have a cat on it.

I will be happy with what ever number it hits but at the end of the day it's just a number.
 
The transmission knowing there is a test today.

I was waiting for someone to pull the price is right card.

Anybody up for the side bet of a babaganooked 4L60?

I'm an ass... But someone has to be one.

All seriousness, good luck on the Dyno time. May you get all the horse-torq's you were hoping for.
