I have a post in the 24V engine section, 2400RPM defueling problem. I cant seem to find anyone who has any answers for me, Please check it out.

thanks mark

 

Mark, I checked the thread and I agree - you shouldn't be defueling that early.

What kind of dyno was it?
What gear did you pull in?
( I know - just covering the basics)

 

Thanks we gotta start somewhere.

dynojet .

3.55 axle, locked in overdrive, TC locked up, sampling at 1500 RPM.

 

So the engine defuels how? As in - no more RPM, or more RPM but HP & torque falls off dramatically?

The Red Line box is the only run when it didn't defuel?

Ever dyno in stock (or reasonably close) trim?

 

at 2400 the HP flattens out, the torque falls as it should and the boost drops, (see the Dyno sheet on the other post) it seems to be the same with the redline, the rpms still pull to redline, 3400 or 4000. but it struggles to get there were it would normally snap right to it. I will fix the diff and go back to the dyno and see what happens.
