- Pinion : I have changed my pinion several times, from 14T to 18T running a 5.5 LRP X11, but there is no noticable change in temp. How can I determine the correct pinion to use and how do you guys keep your engines cool enough ?
I suppose these are questions many people wonder about, so I thought why not start a theath, that can be used as a reference.
Thanks.

Hi
Slipper too tight - under full accelaretion from a standstill it will not slip - a locked slipper like this usually means you will loose the back end coming out of bends under full power - a slipper absorbs power so its not so abrupt (exaclty same principal as a clutch on a real car - without one you would just stall the engine)....too loose it will slip like mad - car wont accelerate too well - same as a real car with a knackered clutch!
Slippler should slip for a metre under full acceleration from a standstill on a high grip surface - adjust it until it does.
To test whether diff is tight enough (tight enough means slipper slips before diff) - lock all wheels by putting car on the ground - turn the spur gear with you finger (may have to press hard) it will slip on the shaft..(between the pads).
If it dosnet slip on the shaft i.e. you are turning spur and the shaft- then the diff must be slipping so tighten a little...(assumming slipper is not locked totally)
Read the gearing chart for your motor (get it off web-site if you dont have) it will give you a final drive ratio.
Then using a 501x gear chart - available on here you can see which pinion to use...every motor requires different gearing
ps LRP's in mine and my friends experience run very hot....
