We really would like to know what clutch options are available.

Are you planning on the $US becoming worth something in the future, or the € joining the $US in worthlessness? One or the other. Hopefully it doesn't become like the situation with the British Pound. The Euro is "only" 1.57:1 with the dollar but the Pound is a lofty 2:1, which really suck...

How about the M-Pump modified with 6mm elements from the OM606a?

...power are the OM617 M and MW pumps good for without changing the elements, only governor modifications/adjustments? Several have done the MW limiter mod and supposedly its good for around 175hp but nobody has put their car on a dyno after doing it. I got an M-pump today and I'm planning on having...

Johnswe kirjoitti:Building a setup based on twostep charging - two turbos with different size to reach low lag and high pressure.

You would be better off using a single VNT/VGT turbo. A GT3788V or Holset HE341Ve will spool just as fast as, if not faster, than a twostep turbo setup and easily support 400hp.

Here is a thread.

Be careful with that K26. It's an inefficient turbo, the compressor basically turns into a heat pump above 18psi. The reason you have higher boost is that the wastegate can't flow enough for your higher performance. The small turbine housing means EMP will be high as well. Propane is always very ris...

AFAIK Sprinter 270CDI has only 330Nm. In the C or E-Class the 270CDI has 370Nm. But you do not have much options on clutches because the 270CDIs were the biggest machines, which you could buy with manual gearbox. cu Rod Wasn't the C30 CDI AMG offered with a manual transmission? It had 540 nm / 398....

I'm interested in more info about your sprinter clutch.

How much power are you putting through it?

If you want Holset, go with an HY35. The 9cm housing will spool much faster than the HX35's 12cm housing and it's still capable of 35psi.

Thanks!

Has anyone tried compound turbos? This setup is common for diesel pickups over here to increase the pressure ratio above 3bar. I've got a GT2256V mounted to my engine right now and a stock KKK K26 leftover from the conversion. I'm not looking for more than 30psi of boost, but the GT22 won't make muc...

HoleshotHolset kirjoitti:If the non-turbo OM606 can be used in a SuperTurbo buildup, I'll use one of those engines since they are much more plentiful here in the US.

Yes, I'm very interested in the answer to this as well. It would greatly simplify things over here.

winmutt- kirjoitti:How the heck do you get a torque wrench in there? I dont even know what the torque specs are but just gave it a few good turns.

Just use German Torque on them. Guten Tight.

I was only getting 1/2 travel because the screw broke out during an adjustment. It wasn't until a year or so later that I learned how seriously that damaged it.

Any news on 4-speed manual durability?

The tube was no problem, I had forgotten to tighten the clamp in that video.

I haven't solved the sound problem yet.

I'm getting a long hissing sound from the turbo when I change gears and for a few seconds after a shift. I'm a bit confused as to if it's surge or not. It's a whoosh like a blow-off valve, not the stereotypical scissor sounding surge. Here is a video of my engine. When I let off the accelerator, the...

I'd bet if you keep it under .35bar/5psi boost, use a pyrometer, keep a *close* eye on exhaust temperatures, and don't get greedy with the fuel, the engines lifespan won't be too significantly reduced.

The nonturbo engines are not built to handle a turbo. The stock turbo engines have many different internal changes for strength and additional cooling.

With a 3.92 I bet your 2nd gear take-offs are much better than mine. The USA did not have any MB's with the 3.92. The lowest gearing we got was 3.69 in the 240D (Which I have).

18 sec? Yours non-turbo?

Now that YouTube has FINALLY :mad: got my video active, here it is: http://www.youtube.com/watch?v=uLgEnnQaR54 I do a bit of revving to get the turbo going and I get to 60 at the top of 3rd gear. Nothing amazing, it's only about 1/2 second better overall. The video I have is 13.6 seconds 0-60 and th...

The engine is an OM617.952 so it started as a turbocharged unit. Everything is working great so far. No regrets about the turbo. I'm working on an electric valve that will route the actuator air through a manual ball-and-spring boost controller. It will be operated by a WOT switch on the valve cover...

What is the minimum acceptable intercooler piping size for a 617? The biggest diameter I can use in my plans is 51mmOD because of clearance issues. I have access to lots of Saab 900 piping that would fit my needs very well. But, it's cast tubing instead of regular rolled tube. That reduces the ID to...

How do you trigger the VNT system of the Turbocharger? What else did you modify, maybe injection pump? How much hp do you have? The vane system is controlled like a normal wastegate. Pressure actuator linked to boost pressure to automatically limit boost. Only downside to this is that it's always a...

For a pre-turbo Pyrometer, 1250*f is a safe limit. For post-turbo, 950*f is safe. In an ideal world, you should have an EGT gauge for each cylinder to monitor the performance of individual cylinders. The best alternative location is where the exhaust collects before the turbo inlet. Here is where mi...

Here is an OM606 that recently sold on eBay: http://cgi.ebay.com/ebaymotors/ws/eBayI ... &rd=1&rd=1

Am I reading correct that you are getting lower pre-turbo exhaust pressure than intake boost pressure?

While my turbo is currently the small KKK K26, I get exhaust pressures of 22-25psi when I have 14psi of boost.

I thought that drive pressure would always be higher than intake pressure.

The OM606 has 4 valves per cylinder instead of 2. This allows it to flow much more air through the engine.
