Engine/Transmission (1994 - 1998) How much power will I make with these mods??

[RSchwarzli]

So I ran into an issue. I think I have more power than my clutch will hold on the crew cab project. :{ My current clutch is a South Bend Con OFE rated fro 450/900. I originally installed this one way back when I started the restoration 4. 5 years ago and was staying with a single turbo. As I am calculating tonight though, I have a feeling I am over, make that WAY over, what the clutch will handle and the last thing I want to do is get this thing finally running and find out my clutch is frying!



For those who have the knowledge, please give my an idea where I will be at. I am trying to avoid guessing so the closer you can get, the more it would be appriciated!!



My motor is set up as follows:



1997 CPL 2174 (180hp auto)

HX35W (Stock - nothing changed) and PDR HT3B (26 cm3 housing)

ATS Exhaust Manifold

Banks Twin Ram Intake Manifold

#10 Fuel Plate

3000 RPM GSK

FASS 95 GPH

Timing 16. 5 advance (if my memory serves)

AFC Spring Kit

DDP Stage 2 injectors

181 Taper Cut Delivery Valves

60 PSI Intake and Exhaust Valve Springs

24 Valve PDR Intercooler

Magum Something or other intake filter (came from PDR)

4" Exhaust

Cometic Head Gasket

ARP 12mm Head Studs (I think - Was 3 years ago but I do remember I just re tapped the holes - I did not make them bigger)

Fluidamper







I hope that covers everything that is power related.



One last question. With the way that is set up, do I need a smaller HX35 housing (like a 14 cm snail) and do I need a larger waste gate than the one thats on the HX35W?



Thanks!

there are so many variables that it will be impossible to tell the horsepower without a dyno. were is your plate. hows the pump set up ect... i would guess your would be around 500 with twins but who knows till you just pay to have the dyno done. good luck and if you spent that much on her just a couple hundred more won't kill ya lol. on my setup i am right about 450 i was 407 before my injectors and i would guess they added about 50. good luck.

Your stock turbo has a 12 cm housing. Most HX/HT3B twin kits used either a 35/40 hybrid (14 or bigger housing) or a 40 depending on the fueling. On all of them the wastegate port is drilled bigger and a larger gate is installed. The compressor is also balanced to a significantly higher standard and the compressor housing is machined down for a closer fit.



How long before it makes smoke?

Thanks guys!



Extreme - Smoke will fly in the spring! By then all should be finished being bolted together and ready to roll!



Then again I started this 4 years ago with the intent of fixing a few things. Who knows. It has taken me 4 years longer than expected so... .



So if i gather correctly then , what you are saying is I do need a larger housing and I cant use my current waste gate? Sorry. Just confused.

You might be able to. I'd figure on some turbo work (balance and machining the compressor housing) and modifying the turbine housing as well. I think you're at the point where a call to a good vendor or two is in order. They will give you better intel than a couple of wiseguys on the internet.



Good luck with your project. I'm trying to get mine to smoke before before Christmas.

Thanks Sir!



And best of luck with your project as well! Bs sure to post pics when done!



From my end, I already have a DD South Bend on order. Ripped the transmission out last night and waiting for a package to arrive... .
