more power from your diesel engine

I'm really kind of opposed to "turning up" the power on your engine. Everyone knows that more power = less reliability and durability.

I was looking at the DT 466 engines the other day, and found a sticker on top of the valve cover. It has a little chart showing what the timing and fuel delivery rate should be set at for vairous hp ratings. That got me thinking.....

So i looked for info about my engine and found that the DT series, my brazilian ford, and the cummings mechinical injection 5.9 liter engines all share the same injector pump. (different sizes obviously) It seems most diesel engines come with a lower hp rating for the first part of their life then can be turned up after the engine is broken in. Even though my particular engine doesn't have the info for increasing hp rating, i found the instructions on how to "turn it up". It seems simple enough.

I think it's a bad idea. My engine has over 276,000 miles and i'm sure that it does not need any extra stress.

That being said, I think that when the weather warms up, i'm gonna give it a try. What's the worse thing that can happen? I shoot a rod through the side of the engine block? Then i'll be forced to get that new bigger engine i've been wanting.

It seems like a bad idea....but i just can't resist! I'm a crackhead!

The 6.6 liter ford seems to be way overbuilt. However, i immagine it's come to the end and perhaps surpassed it's rated engine life.

What everyones thought on this?

It's not like i'll be increasing the hp excessively. Perhaps just 10 or 15 hp. I won't really know how much, it's not as if there is a skoolie dyno in my backyard. IF i get real ambitious, i might even put a pyrometer in the exhaust manifold to monitor exhaust temps before/after the modification.

put the Pyro meter in..you might be surprised how much you can "turn it up"

If you are talking about turning up the injector pump, I've heard stories of farmers around here turning up the pumps on thier tractors, they usually don't know what they are doing and end up ruining the engine. However I do know a Case mechanic who turned up the HP on his own personal tractor and I believe it is still running strong.

Turning up the power

I've got a question about pyrometers. I'm aware that there is such a thing, but I really don't know exactly how you use one. If a person turned up their fuel pump, how would the pyrometer keep you out of trouble? Also, exactly what goes wrong with an engine if you do turn the power up? Does it just wear things out sooner?

A pyrometer is a temperature probe in the exhaust manifold or headpipe...watching it closely when at WOT keeps you from melting pistons.

for anyone with a bosh inline injector pump like the ones found on the DT, cummins 5.9 idi, and ford/new holland brazilian motors here are a couple links to making more hp

Today i finally turned up the hp on my DT360.

WOW!!!

if i were to do it again, it would be about a 15 minute project, however being the first time it took about an hour.

I only drove about 10 miles or so, but i did climb the tallest hill in 3 counties. I topped it at 50 mph. I should have gathered more data with the bus in stock mode so i could compare hard numbers, but oh well.

There is a significant improvement in power and acceleration. It'll be interesting to see what happens to fuel economy, but i don't think it'll be drastically different. I used to have to put the gas pedal almost all the way to the floor to do 60 mph, but now it's only about 3/4 throttle to get the same speed.

should have done this years ago starting with my first bus!

Yesterday i turned up the IP...see above post, today i'm planning something far more exciting....

anyone ever play with propane injection?

after installing the pyrometer i am plannning a homebuilt propane injection system. Seems safe and easy. I don't need a racecar, i'm just tired of being the slowest vehicle when climbing the big hills!

I'll try to take lots of photos and put together an online tutorial.

most of my other crazy bus projects seem to end well, hope this one also has a happy ending. The dt360 is an extremely stout engine design and is currently running at very low HP. The DT466 is pretty much the same engine and it comes in a version with more than 100hp than the 360.

parts needed:

propane bottle
Microswitch for WOT (wide open throttle)
guarded switch for dashboard
LED indicators
Hydraulic hose
High pressure oxygen regulator
12 volt solenoid
5 psi switch to allow propane to flow only when boost pressure is present
12 volt wire
1/4 turn valve for quick shutoff
EGT (exhaust gas temperature) guage

Wish me luck!

Get the pyro first...also ,what transmission do you have? Some (read: AT545) are right at their limit with a stock engine.

FYI, the DT466E tops out at, IIRC, 275HP. With that rating, it's still a million-miler.

i looked at some DT466/AT545 buses for sale locally last year.

I have the DT360/AT545, a lot less HP than my engines older brother (the dt466). I don't know how much power my engine is currently producing, but since i turned up the fuel delivery rate, and advanced the timing slightly, she's screaming up the hills.

i'm still debating about propane injection

i suppose i should also get a trans temp guage if i decide to go that route. I have been reading lots about propane though. It's nothing like adding nitrous to a gasser. It seems to be quite safe, many times lowering the Exaust gas temps and increasing fuel mileage. The propane and diesel fuel together have a bit of synergy apparently by making the diesel fuel burn more efficiently.
