I have been running into this problem recently...

everytime i run the car upto redline... and then shift fast... the car lags (feels like clutch slipping) really bad for like 3/4 of a second... then the car lunges forward as the power kicks in...

Now my clutch isnt slipping as i ve run it in 5th and boosted all the way from 2500 RPM to 5000 Rpm's

Is it the pressure plate? or something more serious like the rear diff...

simply put you have all this power to redline ... shift wait for a second and then the power kicks in...

Now the only way to shift properly at the redline is a granny shift.. and let off the clutch slowly...

 

anyone ???

 

It's the clutch, I had the same problem.

 

lol @ drivetrain lagging.

Get a smaller drivetrain so it will spool better lol
















I think you need to give a better discription, when you say lagging what do you mean? Do the RPMS jump then grab?

 

Actually the rpms drop...
