hi guys , need some help iv got a mc3 ac with a pm pipe and a polini 6 roller veriator , is there anything else i can fit to make it a bit faster with out getting a 70 kit ??
To put it simply... No. Adding speed is done by adding power (70cc kit) then all the other parts make use of the power.
70 kit should of really been the first thing bolted on, get yourself a nice sport kit and run from there. The difference afterwards will put the biggest smile on your face!
