does anyone know the differnce in altitude on a dyno as far as horse power and torque compared to bieng at sea level and then bieng 1800 ft above sea level.

There shouldn't be any significant difference. The correction factor allows for altitude, ambient air temp, barometric pressure ect.

True.But ya have some guys that are like the guy at the meat market that puts his thump on the scales

For actual HP loss from sea level to 1800 feet go here http://www.wallaceracing.com/braking-hp.php

Check out their other calculators http://www.wallaceracing.com/Calculators.htm

air temp i think would make more differents

Mark thanks for the link that pretty cool.I didn't loose much


Your BHP loss computed from your BHP of 848 at sea level and Elevation of 297.5 feet is 7.57 HP loss.


I wonder if water temp like a cold lake would make much difference .I bet it would on the innercooler,but not much on the motor.

I know we left the water off on innercooler on a dyno pull,it made about 48hp less and it made 2 lbs more boost

That would got back to like CustomRigger101 said air temp making more power

This calculator is way off.

Your HP computed from your 60 Foot Time of 1.498 at Weight of 4040 pounds is 1,113.83 HP.

Don't think it was designed to work with a boat

I think chiller temp would be a significant factor, colder the better.

At that HP it prob figures with a boat Mine was only 700HP.

Thanks again for the link there some good stuff there

Colder H2o is better for the intercooler but not as good for the bottom end of the motor. On our Nascar motors from about 150-250 degress F. there is about 15-30 hp.
