(07-27-2010, 09:51 PM)GREASY_BEAST The method you are advocating is called "guess-and-check" and it is most certainly NOT what any intelligent race team will do.. There is a reason they have computers and math and stuff...Exactly. There is a map for damn near ever compressor on the market and there are several turbo calculators on the net that will even plot out the airflow and PR for you!
Here is one already setup for a factory OM617a: http://www.not2fast.com/turbo/glossary/t...utyCycle=0
Quote:Gee, what a warm and friendly welcome to the forum.You know the saying, "you made your bed..."
Quote:Again, not looking for a "kit"--just looking for proven/reliable upgrade combinations for the 617A newbies.Pyrometer, VNT turbo in the GT20-25 range, intercooler (air or water, doesn't matter), high output injection pump and fine tuning of all the injection and transmission settings.
Or if you want a simple and free jump to 145hp; Install a pyrometer, yank the rack limiter and set the boost to 15psi.
There is no universal "kit" by any definition. What parts you choose massively depends on what you want the car to do; track, autocross, rally, drag, high altitude, desert heat, the arctic, highway cruiser, stoplight sprinter or just a well-rounded sporty daily driver. Somebody might be fine with a tiny instant stump pulling torque VNT while somebody else wants a sky-high rpm extreme horsepower HX40.
What do YOU want to do is basically what everyone is asking.
Quote:Well I have a W460 G-Wagen LWB, 4spd manual....currently 617(non-A) w/ 88hp.Thats your big limitation. The non-turbo 617 can't reliably handle additional stress (thermal and physical) from a turbo. MB completely redesigned the engine internally just to add the 9psi of boost. You can add a turbo and turn up the fuel it will make more power, but don't expect to see big numbers without bearing or piston failure.
I'd experiment with the non-turbo engine but have something waiting on the sideline to replace it.
