if u ever look at a dyno sheet from a 2200 motor it has a fuel cut off kinda at around 5200 RPM's ..it's on all of them and i was wondering if u could bypass it

Do you mean the rev limiter, where it won't go any higher than redline?

look at that and look at the RMP range it has a fuel lag that drains HP after 53000RPM



no i mean when u drive and u hit anything after 5200 RPMS u are basicly losing power cuz it has a fuel lag or cut off

dont think thats fuel lag, but more so the end of the powerband. redline is 6k

^^^^ Bingo. It is normal for all engines to have a "power band" in a specific section of the dyno graph. That's where power peaks and then drops off. I'm not sure there is anything you can do to eliminate that drop off. It's not a result of fuel lag I don't believe- though you might try upgrading your fuel delivery system and letting the rest of us know how that affects the dyno chart.

Fuel lag

Listen to what the people above you said. If there was such a thing as "fuel lag" You would be running extremely lean and most likely blowing a motor. Your simply seeing the motor run out of its power band as stated above. There is no such thing as fuel lag.

well it does lean out a little bit after 5300RPM's or so
