Turboed XM @ 6-7PSI
I am wondering how I can build more "load" into the clutch system as the XM keeps triggering the what i assume is the "rate of RPM limiter" - if i punch the throttle (usually happens around 6000 - 7000 rpm - cuts right out).
The is no over rev displayed - as It is not over reving because if i slowly increase the throttle to full it lands around 7400RPM - no where close to 8300. If I put it on clicker one to decrease RPM I can then punch the throttle again but i cant get full rpm as it lands about 7000 RPM - but the rate of RPM limiter does not get triggered. If i try to increase the clicker - to get proper RPM (7900) I can't punch the throttle at all - it just triggers the rate of RPM limiter. I have to stay under 7400. If i try to increase RPM or increase boost from 6 to 7 - it immediately trigger rate of RPM limiter when i punch the throttle.
I tried stock secondary - way way worse!
Someone told me that a 43/47 Helix works well on the XM turbo to add more load to slow down the rev rate so the limiter is not triggered. I am not sure what the angle of the Cudney CR-8 is that i have in it.
Current specs:
