**1****Calculating Actual Power Made. Challenge me! lol**

Hey guys, I just made a pretty neat lil spread sheet for calculating mustang dyno hp, interceptor calculated hp, pretty much anything that measures hp, I should be able to plug into this excel spreadsheet and find what the hp is at the wheels, or the hp is at the crank.

All I need is your stock calculated number you got, im going to assume the true wheel hp is between 238-240whp, and crank hp is 260. Also need you calculated hp number you got after a tune or aftermarket part added.

then I just plug the stuff into my sheet and wah-la I can find your actual hp gain in whp or crank hp. Let me know if you guys are interested in finding this out or at least seeing how accurate my math is

on top of this, I can compared hp gains between different cars on different methods of measurements and see if they make similar hp or who's car makes more hp with that modification since im basing everyone off the same stock hp number! this will be fun if it catches on

post the following info

**4**Hey, Terminator, does that sound about right for crank hp gain?

oh i see. i don't want to be misquoted and be called out for inflating numbers. haha.

here is at the crank- 321.58 + 61.58

here is at the wheels - 294.37 + 56.37

no more changing i swear

This was on just a tune, now I have a catless DP, and I'm running 25.5PSI, any thought's on my current numbers? (once I get the stupid actuator fixed... )

according to BTF, we can use the VE airflow (lbs/min) PID on HPT to estimate WHP, just add a zero to the measurement. It may be slightly low for FWD guys though, say by about 3-5%

It's cool because he owns a dyno and probably has the most runs under his belt of any kappa out there.

**15****you have a 52.44 hp gain at a crank hp of 312.44 hp.**

sorry I didnt repsond right away. I thought this thread died, lol.

Yesterday I worked from 7am to 11pm. somewhere in the middle of that I installed my friends invidia 3" exhaust on his wrx. Thats was a good 1.5 hours are harsh labor

For instance, my MAF lb/min is around 30, so multiply by 10.5 is 315, account for drivline loss of 10% and you get 283. And my VE is right around 26 so multiply by 10.5, and thats 273. Pretty close IMO. I blieve I make more than 273 though, lol.

Cuda, my IPOD says I made 360 hp once... what does that equate to? Lol jk jk!!!
