either change the governor spring or have weights taken out of the pump. to have weights taken out you need to have a shop do it.

and to which i reply-------------why?????????? even when mine was running, boost up, pump up,turbo engine---i needed no more r's. as it was to the end of hp and torque--i/e falling off--

Because for pullin, more RPM's helps keep it going because more momentum

Well you can call it 2 on 2 because it doesn't make any sense to me either.

I can't see why you;d want to go any higher either. If you want to kick it upo some, turn the fuel up and maximize what you can get out of the effective range of the engine, but you start going over red line and you are playing with fire as far as balance issues etc. The thing just wasn't designed to hold together at higher RPMs.

This was one thing I recall that Ken did with the DPS pumps was to bump up the rev limiter from 3350 to 3850. I don't know if the Moose Pump does that as well or not. I'm scared to hold mine at 3350 for very long let alone over that. It just scares me that a valve spring might break or I would float a valve or break a rocker or something like that. As far as the balance, don't you think they were probably overbuilt a little(IE maybe balanced to 4000 RPM?) maybe not? I'm not going to try it voluntarily again. Mine held together in the runaway situation, but I don't even know how high the revs ever got. It could have been only 2500 and I still would have been scared s**tless as I was.

my revlimit is at factory set limit and mine hits 3800 all day long, 3300 sounds low to me, and its my motor if i want 4000 rpm then i will have 4000 rpm, and if i blow it apart then its my own fault and i 4 more engines laying around to drop in it, i tach mine to 3600-3700 very often havent had any trouble out of my engine still runs like its brand new

my fuel is already turned up

Calvin says the valves start to float at something like 4200-4400 rpm's

thats probly true, i have no idea what they float at, but 4000 is all i want on a stock motor, is i ever get to build mine the way i want im going to find some better valve springs that will let me turn close to 4500, but that in the future down the road

I would think you would need to special order up those vavle springs, we dont have aftermarket "high rpm" springs available to us.
