no i havent, sorry... and i would really like to make some runs dialing in the boost pressure, but i unfortunately do not have boost control, and as far as i know, the wastegate is not adjustable..

Check out the intercooler link in my signature.

Simply installing an intercooler will NOT give you instant additional power. You still have to turn up the pump. At most, you will probably get 2hp from the increase in combustion efficiency.

Do You have $12 Juggernaut? Do me a flavor get one of these: (feel unhappy for ya if somethin in that engine melts)

The wastegate is adjustable But It takes to much time and effort so just get some rubber hoses from a hardware store and pop that $12 boost controler
on and get it to the right setting you stated that you had a boost gauge and a pyrometer right? Just do it

Where did you get that pyrometer i need one? Thery're expensive so does any one know where i can get a descent one for a good price

PS boost controler works I have one myself its just a ball bearing with a spring. I think thats how all manual boost controlers work The Expensive one just look nicer

Don't waste your money. Why spend $150 for $35 worth of parts?

I'm new here, so I shouldnt even say but, Jugegrnaut, man, you must have a machine shop and a few shortblocks laying around to be playing like that. Or put another way, why turn up the dial to full on before you measure performance to find peak system efficiency. Spend some dough on a GETCH and check 0-60 times at different boosts. Or a chassis dyno session. Some form of real measurement.

Again, being a diesel noob and blown diesel virgin, still it would still have to flow a bunch more fuel to be effective, then there's cam timing ,etc. Just saying you should find the sweet spot of the system, and baseline things so you dont needlessly push the bottom end.

Dont trust your " glut dyno " , measure it.

Please explain how to get this for 35.

I have heard rave reviews from a diesel truck driver with several MB diesels this is an excellent system.

Aluminum pipe :$10
Cheap-o reusable K&N wannabe air filter: $10
Hose: $5
PVC tube for oil separator: $2
Brass fittings: $5
Hose clamps $3

It's a junk system. It draws in warm air from the engine bay, has a 0hp gain, it's all sound and no go, and it replaces MB's very well designed air filter system with cheap inefficient crap.

Ever heard the phrase "all show, no go"? That fits it perfectly.

The Benz engineers designed the stock air intake to bring cool air from outside the engine space under the hood......I am unsure if the placement on W123 models will gain any positive air flow in relation to speed (ram air)....but the air to the turbo will be way cooler for sure!!

SB

Note: the W124 diesels have a small louvered area in the right front fender to allow cooler air into the intake.....never owned a W124 tho!!!

Excellent recommendation, Brian. I have personally done this on two different cars ('84 and '87 300D) and the results are quite interesting. Mine wouldn't go past about 17psi, though. With the wastegate operational, normal boost was in the 12-13psi range.

Now that I have an IAT gauge on the '87, I'm tempted to repeat the test, to see the actual increase in IAT.

I keep hearing about how expensive it is to get a pump from Myna Diesel but haven't seen any actual numbers. Expense can be relative. Are we talking a grand? Five grand? Does anyone have any recent info? I've done some cursory searches for info and haven't turned up much.

The fact that I don't have a turbo yet hasn't dissuaded me from accumulating info

there was a member here named brandon, he is banned now for some reaon, i think he talked to the people and it is around $2K

A guy on the Bimby forum had Myna modify an OM617 pump, and a couple other people have gotten formal quotes for OM603 pumps. All prices I've seen are approximately $1000 EUR (roughly $1250 US), for them to rebuild and modify a pump you supply. If you want to buy one outright, that might be more like $2k. This is for a fully rebuilt, modified, and calibrated pump set to your desired horsepower levels. The external full-load adjustment alone is just about worth it for the time savings.

Thanks guys. Good money for sure, but not as insane as I was thinking it might be. I'll file it away for future reference.

I think there was some stupid high amount of shipping charges. For some reason I want to say $800 round trip.

I would love to be wrong.

kta-cummins right?
