Great Post!

i was wondering what a safe exhaust temperature would be for my 93 non-turbo. i dont want to put in too much fuel and end up burning holes in my pistons.

I followed every step except getting the pyrometer and it worked great. it was pretty easy to do with some help from a buddy. i can feel the power gain on the hills and it blows black smoke.

:U:so how much smoke did it blow. how bad did it hurt your fuel economy??

Yes a 6.9 block and 7.3 block will interchange. And the 7.3 block is better cause it has stronger cylinder walls. And i also turned up the injectioin pump in my truck. i liked the gain, and yes it does blow a little bit more smoke. But its sweet!:ok1:

the idi engines both interchange, and on the outside they are identical. so as long as the 94 is not a di powerstroke do it. some people actually prefer the 6.9 because the cylinder walls are thicker. but this only matters to engines that have suffered severe cavitation. 7.3's are more prone to cavitation problems because there cylinder walls are thinner. i hope everyone is using coolant SCA's to prevent this.

So if i put a three inch straight pipe, better flowing intake and turned the fuel pump 1/6 of turn clockwise how much of a power increase would that be around? Would anyone by any chance know?

I did basically all wat u said, but wit 4inch exhaust and advanced my timing 5 degrees and put on electric fans. I dyno'd my truck and put down 150HP@2860RPM and 320LBS/FT@1840RPM. Mines a stick and thats with 33inch tires.:rocking:

Oh allright, mine is an automatic and it came from the factory rated at 170hp and 338ft of torque at 1400rpm`s. So by doing all of the stuff I mentioned earlier how much of a power in crease would that be?

about 15-18 hp and 30-40 ft lbs of torque
