power guesses
hey guys I'm new here, just recently purchased a 94 12v, truck has a lot of power, plans to get it on the dyno but wondering what kind of power you all think it might have.
440 marine injectors, lazer cut delivery valves, no fuel plate, 3 piece manifold, air dog fuel system, 4k gov. spring, straight piped into single stack, 180 cam, stock turbo w modded waste gate, k and n intake, cfm+ elbow, built trans.
the stock turbo is killing it I know upgrade to come, but what kind of numbers do you think it running?

yeah ... WAY OVER FULED ...... Egt's have gotta be rediculas ....
Whats your timing set @ ?
Do you have Studs ?
Make sure you get the correct plate .. like a 100 or so .. unless you get something to stop the fuel pin ... it can be hard on the rack to keep bouncing off the housing .. I recomend a plate ground at the minimum ...

I got a similar question, any comments would be appreciated! I haven't got a chance to dyno mine yet but would like to get an opinion on how much u think I'm putting down. Got a 98 12v with a 0 plate all the way back. 191 delivery valves, 370 marine injectors, marine pistons, marine cam, 4 inch turbo back, dodgezilla turbo, pushes about 48 psi, and head studs. Any suggestions? Thanks.

your boost is an indication of extreme drive pressure. You will probably gain 20-30 hp alone by letting the front 3 cylinders wastegate at 32-35psi. Unless you have modified the divided in the turbine housing the rear 3 cylinders will not gate.
your back pressure must be like 2:1 compared to boost.
Suggestions:
1) get a bigger turbo with at least a 68mm turbine. Prices start about $1300
2) if you can't/won't spend money on a turbo upgrade lower boost to 32-35psi, remove the turbo and drill or cut the divider to allow the exhaust to wastegate all 6 cylinders.
--- you might as well have a 2" exhaust as your system is NOT free flowing with that much restriction in your turbo.

dodgezilla is 60mm hx40 compressor wheel with the same bottlenecked hx35 turbine housing. estimated flow of 66lbs/ minute depending in wheel design. It is limited in the HP it can support due to drive pressure.
unmodifed hx35 turbine housing 12cm only gates the front 3 cylinders.

A 64 turbo would be great if you have an automatic for the strip but for driving the streets they suck. You won't have any boost until 2200 rpm. I had one on mine for about 2 or 3 weeks then went to twins. But I have a 5 spd.
