The trick with the duty cycle equation is afr.. Since I'm too rich my duty cycle is to high thus giving me innacurate numbers. My duty cycle is 81% so .81x325=263.xxhp

I try not to push it too far past 7k on stock cams an sprimgs and I'm not upping the boost till I can get on a dyno, it holds, 11psi pretty good.

That red run I did see a slightly higher duty cycle at the end, that one was 81% the blue run was 79%

You're using Scooby injectors right? Or did you switch to something else?

Something I was just thinking about, I wonder if having the windows down has any effect? Somethings I have my windows up an some down but I've never really thought about it all that much.. I know if u increase the drag coefficiant in virtual dyno it will add power to the graph, so I wonder if it works the other way around an takes power when u do a pull with the window down.

Mythbusters did an episode on drag with "MPG, Windows up vs. Windows Down" basically they would do a run with A/C on and with A/C off with the windows down and A/C caused more drag than having the windows down without the A/C on.

I Think there may be a somewhat noticeable difference if you had the windows up (without A/C on (if you still even have the compressor on the crank) of course )

Hmm I'll give it a shot next time and I remember that episode lol


What's this a/c you speak of?

It's quite a wonderful thing actually. More for a daily driver application very rarely seen in racecar's the A/C's mystical presence is obtained through a lot of hard work and sacrifice in HP's

hahahahhaha
