Engine/Transmission (1994 - 1998) 400 Hp Best Way To Get It

[KNaugle]

I own a fabrication shop and our 1995 shop truck is due to be rebuilt. We are going to make a project out of this truck from the frame up. I would like some advise on good way to get to 400HP with minimal heat problems. We are going to start with the bottom end. I also would like to stay with a single turbo. Truck is a 1995 5. 9 @ 175HP with a 5spd. Product names would be helpful.



Thanks for the input

First, 400 hp will smoke your clutch. Plan on getting one of those too. Heres a shopping list:

GAUGES... I would do this before anything else. Boost and Pyrometer.

SouthBend Con OFE clutch

4" exhaust

3000rpm gov spring kit

370 injectors

Some sort of better flowing intake

62/14 turbo from your favorite manufactors, Industrial Injection or High Tech Turbo.



That should get you to 400hp and probably above that too.

Good combo but you will end up looking for a bigger pump.

I have somewhat of the same set up, but I have the 4000rpm gov springs and an FE clutch, with an hx40 turbo and its making 450 to the wheels

Have to agree, I had similar, but add 100 plate and 191 d/v's netted me 383/893 on dunbars dyno with a 175 pump. Skip the ofe, go right to the FE if its gonna be a heavy truck.

With a 215 hp pump. Big diff between the 175 + 215

 

[arthr31]

lemme ask the next question...



if you had a 215 pump, what would you likely be putting out?



And, how can you get a 215 pump? (no, i have one, thanx)...



the performance question comes up a lot, is there a magic bullet ? Like, is Ben's ingredient list a good place to start at least? Thanx...

 

[Signal73]

Id think low 500's easy. Ben defenetly has a proven recipie for nice HP there. You can get a 215 from places like Industrial injection or mid west fuel injection just to name a few... Stay away from ebay remans... Been there done that.

I took a 175 Hp truck to 450 HP with 191 DV's, 370's an HX-40 and a custom plate simualr to a #100.



Also timing was @ 16 deg with a 4" exhaust.

I would suggest a set of DDP Stage 4 injectors. They make more power than the 370s, with less heat and smoke. Bigger delivery valves are in order as well.



I'm putting down 363hp to the ground. Still have stock gov springs. The HX40 is enough turbo, if not towing. EGTs are an issue if you do. My setup works great, minus the EGT issue towing. On the street, the EGTs are a non-issue.

We are going to start with the bottom end.

There's no need to do anything to the bottom end other than the typical crank polish & new bearings during any engine rebuild.



You may consider new pistons though such as Mahle or whatever PDR (Piers Diesel Research) carries which has the piston bowl that works better with Bosch 300 or 370 injectors should you decide to run those. Another thing I'd suggest is gapless 2nd ring from Sealed Power.



I would also suggest having the entire reciprocating assembly balanced.



Lastly if you want to make HP and keep it reasonably cool, definitely add a camshaft upgrade, and maybe port the head a bit - the pockets around the valves give you the most benefit.



If you're wanting to make some power, consider O-ringing the block, and installing head studs

oops. forgot the plate and afc mods...



Are you on a budget for this? Or are you planning to get some big number later?

I would like to thank every one for the responses and will look over all the suggestions, some of these items were already on my list of to do's. The turbo seems to be my biggest problem as far as selection is concerned. Everyone I talked to choses a turbo based on experience but when I start to Question them about turbo effeciency they all scratch their head. I read an article about sizing the turbo correctly and it made me wonder how to get the correct size as well
