OM606 Reliabilty with performance modifications?
OM606 Reliabilty with performance modifications?
I had first saw them last year. Thats what set off the om606 want.And I saw what where they had "oil problems" and broke A chunk of the main journal off the block. now there using a CDI motor and a later model wagon. just didnt know if I am chasing a lost cause. Id like to build a high hp diesel but not a slow revving industrial 4bt or limited hp volkswagon tdi. just hate to build something that mechanically doesnt hold together after some play time every now and again them back to work commuting and getting 30mpg (US)

The normal Swedish way of doing a om606 big power build is to use an old Taxi engine with 310685miles (500.000km) on the meter and then push 600hp out of it (with no rebuild what so ever). And that holds up for quite some time. So with some love and a moderate power of 400hp those engines never break.
To be super safe you can balance all rotating in the engine, shot peen the rods and so on. That's quite some work but will not cost you as much as buying new engines (or forged stuff).

You HAVE to sacrifice some amount of reliability when you start adding more power, to anything. Doesn't matter if it's a merc, a cummins, a vw, or any engine. They weren't made to handle that kind of power, so realistically you can't expect one to last as long as it would in stock power.
That's not to say that a fresh om606 won't last a long long time at 400hp, I just thought I'd point out that sometimes it's just not practical. I honestly think as long as your not pushing extreme rpm or extreme hp, they will last as long as you drive it
Mfsuper90 Thats correct. And I understand if something is designed to run at blank amount of power and now your asking 100% out of it I understand its going to die alot sooner. like a 2jzgte turned up to 1000hp on stock rods and pistons on race gas will last about a month of daily driving with a few pulls. but live a long time at 700-800 depending on turbo size (how hard it hits on low rpm,rods go first)
F.R.A.S Id like to shoot for 500whp on the om606 (just because Its usually been a drivable amout of power for the street on 3liter turbo car, never had twin charged so i just know big laggy turbo setups)
I dont want to sound like a know it all either. Im young and eager to learn. Im still learning about forced induction and thats why im here on this fourm to entertain my hobby of gas and diesel applications. I appreacite the input!
Hmm, is it possible the om606 wouldn't live as long with a set of fast spooling twins? EDH will find out I guess with his triple set. But that's still a little different. I just wonder how the om606 would hold up to full boost coming In at an earlier rpm than a big single
m90 SC thats been ported will safely make how much psi? With that and a Hy35 which had a 9cm^2 as a high pressure to a Borg warner s366 turned up.
I imagine the rods have to give up at some point if you can make more torque sooner. Where can dyno charts be found of benz 6 cyl diesels?
