oh, yeah, understand that. I just wanted the numbers to plug into my Dyno software so I can guesstimate what I should be producing.

Plug this into your dyno soft wear and tell me what you come up with this is what i degreed my cams to

I don't think I have the proper data. For instance, I have no idea what the lift on those cams actually is and I'm not exactly sure how to flag the exhaust. I have it set for 'race headers' right now, changing the exhaust settings makes -massive- differences.

Is the difference between the stock cam and the GSXR cams just duration? Or is lift different as well? I'm using stock 0.240" lift numbers.

I think it hit .262" lift on dial but really wasnt paying attention will double check in a later date as i just wanna hear it run then will re degree it

I figured they had more lift as well as longer duration. Ok, I'll plug 0.264" in it when I get home tonight, probally 6pm or so. I'm also going to go down a step from 'race headers' because I'm not sure exactly what it's classifying those as.

Maybe I'll figure out how to raise the dyno cutoff point -above- 11k RPMs, but I'm not holding my breath.

I couldn't find a way to get more dyno (above 11k RPM), but here's the revised guesstimates.

RPM ----- HP --- Torque
2000 ---- 11 ----- 29
2500 ---- 17 ----- 35
3000 ---- 20 ----- 35
3500 ---- 24 ----- 36
4000 ---- 29 ----- 39
4500 ---- 35 ----- 40
5000 ---- 38 ----- 40
5500 ---- 42 ----- 40
6000 ---- 46 ----- 40
6500 ---- 48 ----- 40
7000 ---- 50 ----- 38
7500 ---- 52 ----- 37
8000 ---- 55 ----- 36
8500 ---- 58 ----- 34
9000 ---- 59 ----- 34
9500 ---- 59 ----- 33
10000 --- 59 ----- 31
10500 --- 61 ----- 30
11000 --- 62 ----- 29

Now go get that thing on a real dyno!

after i swap wiring harness

That looks to be the problem, eh?

Hopefully I'll have a dyno soon too, won't be as nice as yours, I'm sure, but it should be a mite bit better than stock.
