Engine/Transmission (1994 - 1998) 400-435HP on '98

[arthr31]

Hi there,



I'm looking for some different ideas/suggestions to make 400-435RWHP on my '98. It's not a strict 435, just got to be at or below 450 (ConOFE).



I dyno'd last weekend and made 349/789 in 91*F. I'm pretty happy with that number but want to add at least 50 more HP. I also think I need more air since I'm pretty smokie.



This is the existing truck profile/mods:

3K GSK

#10 plate, forward w/ boost elbow (can push 40PSI)

star wheel a bit forward

BHAF

4" MBRP from turbo back

191 DVs

18* timing



I use the truck as a Daily Driver. I tow a few times a year, haul materials several or more times a year, drag race once a month between May and Oct.



What would you do next? I'm thinking a turbo, but I hate to remove something that is working... Any thoughts?



Thanks everyone!

Thanks everyone!

You will at least need to upgrade your turbo. That, and a set of injectors should put you there. You can see what I have, and what I dyno'ed at last week , in my sig. My truck is also a daily driver, and tow vehicle. I also have a valet switch, which I use when towing.

I made 535rwhp on my OFE with about 70k miles on it... horsepower doesn't burn clutches, torque does

I made 430 hp with my setup (see sig) on winter fuel not using the water/meth. You need a turbo and some injectors.

OK, thanks. Two votes for turbo and injectors. I'm thinking about a sps62/12. Good for my application?
Thanks guys...

sps62 would fit your needs perfectly art, i ran a PS62/12 before my current setup.

I made 394 with the 98 in my sig. I also vote for some injectors and a turbo! My 98 has the 180 pump yours has the 215... ... .....

One trip into Eastern Massachusetts to MassDiesel will get you what you need easily after you get your coins all lined up. If Scott can not fix you up,then no one can..... Andy

I live 12 miles from Scott's shop. My truck even knows the way there! :-laf



My thread here is to get some idea of what others have done, products, etc. The next upgrade seems expensive and I only want to have to do it once... ... thx!
