well i went back to the 1/4 last night with the new clutch and tune and the same mph result. kind driving me crazy

i didnt make but a few passes cause the track was packed and i had a nitrous leak and wasted most of my nitrous.........yep shitty

only had one decent full pass and it went 8.47 at 1.46

at the end of the night i made a couple motor passes and went 9.30 at 1.57

keep in mind that i didnt have motor gear in the bike, i had gear for spray

here are pics of the slips






rundown i am 220 suited and the bike is a 04 zx10 head and cams with about a 45 shot.

am i crazy in thinking the mph should be higher.

Your ET seems to be about right for both passes. Nitrous MPH seems a little low, but I'm no nitrous expert so I don't really know for sure. Motor MPH doesn't seem too far off. I have similar mods and mine is running 149-150 in the heat/humidity on the U4.4 and I'm 185lb.

If your WEGO log is showing the tune is right, then I would start looking at the nitrous system components. Just to double check and make sure everything is up to snuff there. Just a thought.

Man I wish I had your problems. Much respect earned from me. It will go faster when it cools down some.

Check your stack height (clutch) losing mph is a sign that the clutches are about to go. Could be slipping on the gas, I had this happen to me before I think my stack height was 52.7mm when it started slipping. I pulled most of those fibers out and reused them later when I stopped spraying the bike and they were fine on motor.
