Holset HX35 Install info on om603
(08-19-2010, 11:11 PM)muuris So you know how weak exhaust valve springs are in OM605/6? And have tried too small turbos on these particular engines?Yes. I have produced over 50psi backpressure on my engine during sudden acceleration and 40psi at maximum output with no ill effects or lack of power. My dyno sessions show a whopping 10hp drop from 4000rpm to 4800rpm, almost completely due to the natural torque curve decline and pump's RPM governor.
Quote:Now with the exhaust housing being smaller and everything else being the same as the HX35, will my exhaust connect right up if I decide to swap from the HY to HX down the road? The HY has a 4" downpipe with it.Make a 6" adapter section. That way you'll only need a small section instead an entire downpipe and you can easily adapt to any turbo you choose down the line.
