Real HP with 1st Gens
 

Ok I'm sure this has been covered before but thought I would see what kind of response I get.

How about a quick response on What HP are you getting with your first gen?

What modifications did you do to get that? (Details, parts, and adjustments etc)

I'm new to this and have already been frustrated trying to figure out the realistic numbers I should expect without breaking the bank. I'm currently rolling a stock motor however getting crap for gas mileage. I sometimes suspect that the power to weight ratio is off and i'm under-powered. Can never have too much right. :) I know this is very open ended but would be interested to know more about what others are doing. Thanks in advance.

Might try adding Automatic Tranny fluid or two cycle oil or Diesel Kleen by Power Service to your diesel, that should bring your mileage up some. A properly tuned injection pump will do wonders for your mileage too.:w2:

My Dually has gotten 21 MPG ever since it was new, has not changed a lick, but its always been run on Farm Diesel till I got it and put the first shot of Diesel Clean in it. Had good luck with Diesel Kleen by Power Service before, it should serve me well, here you can get a 150 gallons worth of diesel mix for $16.88 at Walmart. That's cheap to keep your sulfur requiring injection pumps lubed properly. I think at least. :choochoo:

I have never ran on a dyno but if you use the HP calculator with the time and speed i ran in an 1/8th mile i have around 320-345 or so.

i use 20 oz of two stroke boat motor oil in every tank

The guy in that link I posted says to use 1oz to every gallon of diesel fuel. FYI.

I get 13mpg in my '89 Dually with a 93 12v, if I'm lucky empty, tailwind and downhill. My '95 consistently got 22mpg empty. I have been pretty disappointed in my numbers. Since I"m still stock I have nothing to write home about for HP. Local guy wants more money than I can afford to have him build up the power. I will learn as I go heck I will have the front back in with new parts tonight, new seal etc.... Hate paying for something that I can probably do myself. Love this site learning a lot.

Turning up the pump is in the sticky and easy to do yourself but you want someone with a 2x6 board ready to shut down a run away engine when you turn up the pump, just in case. The manual fuel shut off is handy too but does not always do the trick if other problems arise while turning up the VE pump.

At least I thought it was in the sticky, but other things are there like how to install a fuel pin, etc.:rocking:

There is much more to know, you first need a set of good gauges before you get crazy.:lol:

You haven't said what transmission you have. :pca1:

Sounds like worn injectors, timing off, something. Mileage shouldn't be that bad. As far as HP goes, I made 972rwhp with my 1st gen, but I'm not relevant to most conversations :jump: Give us a dollar amount and the trans you're running, and we can give you a good power combo. Or you could just check here.....

Dodge Power Combos.... Page1 - Diesel Power Forums at Diesel Power Magazine

Holy crap! You are the one! :clap::up::rock:

I try!!:c:

STOMP and KTA and I have been in it for a while. STOMP still has made the most fuel only at c.650rwhp. The whole story is here:

Total Performance Diesel Big Gun Shootout - Diesel Power Magazine

Those are incredible numbers for sure. I would be happy with about 325 or so...well I say that now but you know how it goes. If I had that then I would want more.

As far as transmissions that's a good question. PO told me it was a 700r4 built by his tranny guy that did his drag car. I seriously doubt that but not 100% sure how to tell I need to find the numbers on it. It has a gearvendor overdrive and I don't know the rear ratio and or the ratio with the gv in place. I will say after all of the monkey shit I have found this week tearing it down to the the front oil seal I don't think he had the right information or told me the right information. Supposedly this was a professional install by Cummins NW. If they did this kind of rigging then they need to be taken out to the back 40 and severely beaten. I'm by far no expert but common sense on some of this stuff should prevail. I guess that's what I get for thinking.

So back to the subject. Money and Trans, well I don't want to change the trans as I don't have money for that but I would like modest hp with decent mileage and I am guessing that can be achieved. I have contemplated bailing and going to find a dodge with a 12v that hasn't been patched together but then I think there has to be light at the end of the tunnel I just hope a train isn't attached to the light.

Tomorrow I will look at the turbo and see which one it on the truck. One thing I did notice is that my turbo is inverted running an industrial setup, the truck has a bs IC setup on it that I'm going to have to replace. I was told it had bosch injectors and a local diesel performance shop put a pump on it just before I bought it a year ago. He's very popular with the diesel crowd here and would certainly time the thing accurately. One would hope. I did talk to him about the crappy mileage and he told me the PO used to bitch about it to him as well. He wants $1200 to modify the motor to get about 100hp more. I held off as others told me that was spendy.

Thank you for the links I'll do some reading as I have been reading a lot on this site and learning more and more each day. I'll post the trans and stuff tomorrow. Thanks

I'm sorry to say, I knew about STOMP but forgot, I have not had a 1st Gen in a while but I'm back at it again with new funds from a wreck. Thanks for the info. and coming to this site. :):pca1:

I love to join the 400HP club! :D

Jason, do you really have to do an intake to get to 400 HP?

It doesn't take much to hit 300.....I hit 301 with a low stall converter, intake, exhaust, a 60mm compressor upgrade on a stock HC1 and Dynomite Diesel (stage 4) injectors. The truck drove nice, had great fuel economy, and that would have been enough for many people. It's usually the combination I recommend when most people want to mod a VE. I think it could/would have made 350rwhp with some more timing, I was unknowingly only at 9 degrees at the time.

I finally got my truck back together today and haven't figured out what trans is in it but I did take a shot of the exhaust and turbo. Is this a stock turbo? I know the manifold isn't typical and I assume it is the industrial setup. Any info?

Not stock for a 1st Gen, Looks like a HX35 to me, ask Josh.:w2:

---AutoMerged DoublePost---

It should be on that aluminum Holset tag.

Any thoughts on which turbo this is? Also how about the exhaust manifold? I have pulled 2x since cleaning up some issues seems to be better on my temps and no more overheating now it's time to drop egt's even though I don't think mine are out of line and I want to boost the power. I will re-read through here as I think JasonQuarterMile laid it out pretty well. Thanks

I found some information on the Holset website tonight on my turbo. Anyone ever modify one of these? Here's what I found.

You could get an HX40, 2nd gen lift pump, gov spring and gauges for way under $1200. Working on the pump is easy. Tons of good info on here and other forums. The board to cover the turbo is a great idea because you never know when it is going to run away on you tuning the pump.

An HX40 will bolt right up and only requires a slight modification to the down pipe. You can find them on e-bay for under $300. I've seen 45psi out of mine with the mods in my sig plus gov spring. I haven't figured out my mileage because the speedo doesn't work, but I only fill up every two weeks.

The first thing to upgrade is fueling with the 2nd gen lift pump. My stock pump was junk (0psi at WOT and barely registered at idle).

Thats not a industral turbo and yes its stock industral turbos are not waste gated:tu:

Im making around 230 with a straight pipe, cold air intake and pump maxed out.

I have part of it already covered as I have a full line of guages on the rig already. One thing I don't like is my tach floats from time to time, I think it's just a faulty gauge but I have a pyro, boost, manifold pressure, tach, trans temp, regular temp, and regular gauges. Am I missing something?

---AutoMerged DoublePost---

What about manifold? I think that was what I was thinking wasn't stock looking. It's been modded to make sure it clears I'm guessing because of the A/C box is why they inverted the setup.

I could not see your manifold

I wasn't even gonna look in this thread to be honest. lol But it's not an HX35, hx35's have a grove for a snap ring to go into inside the intake housing to hold the silencer ring in place and have a snap ring holding the compressor housing on where as H1C's have a no silencer ring and have that big V-band clamp you see by the oil feed line holding the comp housing on.

That's a H1C off a 1st gen with a wastegated housing added on or a WH1c off a 94-early 95 2nd gen. Nothing special about it.

Nice! I think you are covered as far as gauges go, however, you could always go crazy and get a rear diff temp gauge, air/fuel and whatever else you can think of. Keep reading and ask questions if you are stumped. These trucks are a lot of fun to modify save for runaway.

Air/fuel mixture won't help much on a direct injected engine.

I did 313 with 4" exhaust, bhaf and stock turbo with Prince of darkness injectors, now I have sdx 5x14s, and a he351cw

It'll read super lean most of the time. :pca1:

Haha for sure.

1st gens are boner material... :w2:

That's where the go crazy part comes in. They look cool though...

Oh and im on my 2nd sbc, 3rd input shaft (the current one is cryogenically frozen) and 2nd rebuilt pumpkin.

So does my a-pillar full of gauges. :c:
