I was just curious whether a reasonable estimate can be made as to the HP you're making based on injector duty cycle? Or are there to many other variables involved?

 

that makes no sense whatsoever....just my .02..

I know some people estimate hp by maf g's, but injector duty cycle is unheard of.

 

It makes no sense because you aren't smart enough to understand it. :P

I don't think it's that easy. Depends on the BSFC of your specific motor, the AFRs you're running at, the abilities of your head, VE, etc. Biggest thing by far is the timing advance.

 

Yeah, all that is what I meant by other variables. I guess being that duty cycle is just one piece of the puzzle I should have phrased it as wanting to know if it's possible to estimate horsepower at a given moment by using known variables such as AFRs, VE, RPM, duty cycle, displacement, etc. together. Though I don't know how you could estimate the effect of timing advance on power output.
The curiosity arose from looking at my recent logs and seeing that I'm hitting the excepted 80% duty cycle safety limit of my 550s.

When you gave me this link a month or so ago I had my doubts. After running the numbers and then going to the dyno I became a believer. It was within 10 rwhp for my particular setup.
