I've just won a C4 buggy engine by participating in a race. I know that this engine is no longer sold by R&B but as I won it, I want to use it. But, I've some questions, regarding to the various posts about this engine on this forum. I've anderstood that this engine has a big power, but: the power arrive at more rpm than WS7III the transition low-end ==> high-end is very fast consumption is important
So, is someone could tell me the solution to minimize these problems above. Some solutions could be: use "big" clutch spring (1.1 for exemple) to make the power arrive at the right time. use exponeniel fonction of my receiver to minimize the transition low-end/high end. use 6mm restrictor to avoid consumption pb. use a 15 tooth clutch bell to minimize the transition low-end/high-end and avoid consumption pb
Am I right?
I run with RB S5 what will be the difference with a C4?
A lot of questions, but if someone could help me...
Tanks.

Yes you are right. Use 1,1 springs with nylon shoes for a later engagement of the clutch and a long(er) RB manifold. Also a bigger (teeth) clutchbell will tame the power down a little.
The difference with a S5?....... more power, you will see.

C4 is a beast, if run times are critical, you may want to use an 053 pipe..not sure what pipes are avail now but it's a low-end pipe...don't worry about the top end
I'm currently using the Mugen 1.1 springs and the Ofna 3-shoe clutch..works fantastic.

I'm not running on a track but my Ultra MBX has a taller ratio I believe than some of the others. 13-15T is just plain wicked, burns the tires up on asphalt. I generally run a 16 or 17T to bash around, if I were to race I would definately run a restrictor.
