Bhp?

Here's a simple equation I use:

Horsepower = never enough

I like your thinking!

Another factor is the manufacturer of the dyno. Dynos can be as much as 5% different from each other. Some dynos even have conversion tables to show what this particular manufacturer's HP would be using other dynos.

If you compare a "high rating" flywheel dyno to a "low rating" chassis dyno, the HP difference becomes greater between FWHP and RWHP. There are no standards for the regular guy. The manufacturers have their own standards.

Here's my numbers as example:

FWHP = 608
RWHP = 474 so I divide 474 by 608 = .779 (call it .78).

With this reasoning, I have a 22% loss from transmission, driveshaft, rear end, wheel inertia, water pump, alternator, power steering pump, air cleaner, ambient air temp. (chassis dynos are usually in air conditioned rooms), mufflers, pipes, etc.

I can now back into my post-NOS FWHP by dividing the new RWHP number by .78 to arrive at FWHP from RWHP:

575/.78 = 737 FWHP (I usually roudf up to 740 .

So what this all means is that you need to have a FWHP AND RWHP to know for sure.

Don't forget the Flux Capacitor (FC). A partially charged FC can produce indeterminate changes in the sub-space field surrounding the oil filter and negatively impacting the dyno session.

Among, of course, a myriad of other things that result in having to re-torque your license plate bolts.

I used to think that untill I built a 700hp supercharged C6 Corvette and now with my 484ci. Alum. Shelby block Superformance. You can over power a car. But it sure is fun.
