 New Mods, Now what RPMs? So im in the middle of installing IM heads and a BPS cam, will finish it up tomorrow, on my 35 mudbuddy. Question is, what should i set my rpm's at now. Im running a 12.25 bigblade with a 1854 uncle-j hull. I know i just need to get my GPS and figure out what rpm it performs best at, but what should i set my out of water WOT? With the bps cam can the idle be taken down to around 1000 or so?

Re: New Mods, Now what RPMs? I'd set the OOW WOT no higher than 4400. Even though the IM heads have the valve springs shimmed, you're still running stock pistons & rods. Supposedly they're only good up to 4500. I personally wouldn't chance it, just me.

Re: New Mods, Now what RPMs? You are good up to 4500. Set idle where its steady and you get crisp response on throttle up ~1000->1100. A CDI will idle much lower (800ish) than stock coils.
