all right...so I dont want to jump to conclusions or anything but...when im driving in say...2nd, 3rd, 4th gear at above 3500 RPM and I step on it to full boost the car seems to be ...
it would go from 3500-4xxx RPM pretty fast but catch it self then it does it one more time from 4500-5xxx RPM after that its ok...

I think its the clutch...

but I read up on here somewhere about testing the clutch by going about 25MPH and shifting into 5th gear then put the gas pedal to the metal...when I do that the car just vibrates and the RPMs stay low...and dont rise up fast or jump around...

can anyone think of a different problem this could be?

I have an 05 VIII with Exotic Speed TBE, open element filter, Forge UNOS MBC, AMS LICP, Buschur SS Clutch Line, Buschur Shifter Bushings, and JDM IX Diverter Valve...im pushing 21psi on 93octane...

 

 

Clutch slippage.

 

so i should retest it at around 60MPH? im going to go do that now...crap...now im sure its the clutch...can anyone recommend some clutches?

 

Exedy Twin, then you wont have any problems

 

how is that clutch for a dd? is it safe to get a used one with a rebuild kit?

 

i have one, and i love it. mine is daily driven accept when going to school, because those parking garages are just a b**** sometimes. but i dont regret the purchase at all. its an amazing clutch

 

sounds good...
i gotta find good deals on the exedy twin then...
