Rev limiter on a 325

[philn]

What is the factory rev limiter set to on these?

Thanks, Phil

and how would you do away with one? is it possible without chipping?

M20B25 rev limit set at 6700rpm (i think, could be 6600)

To remove the factory rev limit, the ECU must be reprogrammed.

Well my 323 has it at 6500rpm and I think the 325 is the same but I can't be certain. I think a chip or piggyback/standalone ECU is the only easy way around it but I am not sure.

change rotor arm, some early 325's had no limter. but not a good idea. engine looses power above 6800 unles you have a mental cam but you may end up throwing a rod!!!

M20B25 is set @ 6400rpm (DME) Max power (Bhp) @ 5800rpm
