Ya 3000rpm sounds like a boom waiting to happen . I wonder if you could get some better rods or lighter pistons to be able to safely rev one to 3000-3200. That would be a huge difference in hp at those rpms.My truck would probably be at like 40 psi of boost or more.

A stock multi is between 11-13 psi at 140 hp some run less alot are around 6-7psi.i dont think doubling the boost doubles the hp as the air is hotter and less dense. If i put an inner cooler on mine i might be able to run more fuel than i am now and possibly get mine up around 250hp .But i would...

They definately skimped on the rods. Just do a search on it you'll see it is quite common to throw a rod out the side of the block even without the fuel turned up. Over rev it one time and hello new inspection hole in the block.The gov built these trucks with govs on them for a reason remember...

The two problems that are a big issue with the multi are head gaskets and the rods. Head gaskets are easily fixed with kemetic gaskets. The rods are a whole different problem .the fact that you are slinging a five-eight pound piston becomes a issue. could you get a set of custom rods made that...

all deuces were made to be able to do 56 from the factory .gas motors had dirrect drive for high gear and deisels had od to compesate for the lack of rpm . there is no way to say how many turns is safe to go since every engine is set different as a starting point .best to use a turbo gage and...

well .just like with anything driver is durabilty. you put a 30yr vet truck driver in a race car and he wont brake it .but you put a 16yr old kid in a semi and he will kill the clutch in less than 10000miles when the trucker will make it last a million miles:roll:

200hp is an estimate from the difference in boost vs stock boost at the same rpm .i have a coworker that is an engine builder and we were doing the math together from what he sees on other turbo engines on the dyno .i have no pyro on my truck sorry

on my truck it actually made it faster i wasnt getting enough fuel to get it up to gov speed .it would only rev to 2400-2450 before now it will hit 2600 no problem. but you are correct i meant quicker not faster there is a difference .i gained a couple mph with the extra rpm. like i said every...

i believe mine is around 200hp i have it turned up i'm running around 27psi boost at 2600 it gets around 15 at 1500 .its way faster than stock i have been running it like that for over 5yrs no problems i dont hold on the gov under load other than that i drive it like i stole it...
