That's a shield to run the old gas line past the flywheel/clutch area. This was a legal LSR truck before I got it. I think I'll run the battery cables thru it as long as it's there.

I got sucked into STD (SuperTurboDiesel) on Tuesday for a absolute consumption of an afternoon. I'd say it was a waste, but it was raining anyway and it was priced right entertainment for me. Some of those Finns have the ticket for this Mercedes motor. I'm worried about your checkbook when you get the itch to go faster.
I'm so conditioned to tractor or big diesels that hearing a 5 or 6 cylinder passenger car diesel spinning 5k plus is music. Good luck with your incoming sickness. haha.Last edited by Beagle; October 17, 2013, 04:32 AM.Flying south, with a flock of bird dogs.Comment

To (almost) finish the last series of photos. I finally figured out how to attach the top of the rear dash tin and then went to work on the heater block-off plate. I ran out of the high-temp caulk but once I restock I can rivet the whole deal together. The trim piece on the front edge just WOULD NOT cooperate with pop rivets so I resorted to SS sheetmetal screws and SS trim washers. Nice thing about living on the seacost - there are TONS of SS fasteners at any hardware store.
The pics aren't TOO exciting but it shows the whole dash nearly all plugged up. There are a couple of holes remaining but that's where the electrical stuff came out and I expect to need some of that so I'll resolve that following the wiring.
It's amazing how much time this kind of stuff eats!

Some new pics:
I'm fitting the new fuel cell underhood. This makes the fuel system REALLY simple with almost no fuel line for the engine pump to pull fuel thru.
First shot is the hole in the LF wheelwell. Bummer to have to do this but the S-10 is small enough underhood that it just isn't going to go anywhere else.
#2 - Same as #1 but from a different angle.
#3 - The new cell. This is from Boyd's Welding and is the only one I found that had a chance of fitting and that held a couple of gallons, which seemed minimal.
#4 - The new tank in the hole. The hole looks wide but I have sort of drop the tank in then slide it toward the front of the truck to get it in there.
#5 - A view from the wheel well. I have a Email off to Joe Timney, the ECTA safety expert (Keith is so busy he doesn't have time to breathe) to see if and/or how I need to protect the wheel well side of the tank. I'm sort of back and forth as to the safety implications of this. If the headlight weren't so close I could cut the core support and move it forward but the class rules require the headlight to be there though they don't have to work.
#6 - Not related to the tank but here's all the dash tin riveted in place. Everything is sealed with fire-resistant caulk and ought to be OK.

looking good, DanDoing it all wrong since 1966Comment

Thanks! If I had it to do over I could pull the whole vertical stuff as a unit and make it out of one piece. Next time. Actually I'm reasonably pleased with it.

I haven't harrassed you in a while, I feel derelict in duty. Sure it's a 4bt but...
I was mathing out a 26" tire, 4.10's, and a T5 today, I found an OM617 (turbo 300d) locally for cheap and I have a 83 T-bird that would make a good MPG candidate. What are the ratios on the 4 speed?
that setup would put me in the sweet spot at 75 mph I think. Looking forward to your continued progress!Last edited by Beagle; October 29, 2013, 08:53 AM.Flying south, with a flock of bird dogs.Comment

4bt would flatten my Thunderturd. We're talking dainty Mercedes mills here, about the same as a dressed 302. Dan is opposed to twins... so I suggest this!Originally posted by SuperBuickGuy View Post

Not opposed to twins, just the expense.
No clue on the trans ratios. My Haynes manual is devoid of such data but I'll ask on the M-B forum and see if the guys know. If you want to Google for it it's a 1984 240D trans.
And now you know why I have a M-B engine - CHEAP! Hopefully my enhanced turbo with about twice the volume of the original and the upsized injectors that are on their way will help the old thing. I'd like to find 300 HP but that will require intercooling, which is Phase II.

can you do 300 with the factory pump elements? Everything I'm reading is pump pump pump, I haven't seen anything on the injectors themselves.Originally posted by DanStokes View PostFlying south, with a flock of bird dogs.Comment

I don't under stand if the motor is at rpm but the turbo is not spooled will the super charger not try to blow boost backwards through ther turbo?Originally posted by Beagle View Post4bt would flatten my Thunderturd.

I'm having a helluva time wrapping my head around compounds. The air have to turn a pretty good corner to stall the turbo. One of the guys doing this has a valve that flips between the blower, which makes boost at idle, and the turbo who isn't far behind idle. The blower becomes inefficient once the turbo spools up too. May be using a blow off valve (bypass) on the blower as well since it's an Eaton... just one more thing to think about.Originally posted by Russell View Post Boost on a diesel is not the same as boost on a gas engine, it's all foreign to me. They get into exhaust gas pressure v. intake pressure and it gets kinda interesting. Bob and Geek had a good discussion going on this one time, maybe they'll chime in.

Many of the Detroit Diesel 2 strokes featured compound supercharging. The one we had at EPA had turbos blowing into the Roots blower and made a TON of boost - like 35 PSI IIRC. It was a LONNNGGG time ago!
On the pump/injector thing. I'm starting with the injectors and will add pump mods as I get more comfortable with the whole deal. Most guys don't think about adding fuel thru bigger injectors but this is based on my Cummins experience. In general, Diesels will make more power if you throw more fuel at them up to a pretty high fueling rate. Lots of the guys have theories about pump mods and as long as they add fuel I'm sure they work, too.

Got the gear ratios - 3.90, 2.30, 1.41 and 1.00 forward with reverse about the same as first. These are sort of "more or less" as there are apparently some differences from year to year and application to application but all are close to these. I was surprised that 1st, is that low and some of the applications are as low as 3.98:1 - stump puller with an engine that makes tons of torque (for it's size).
