Stock Turbo - What's damaging and how to preserve

Tzu · 11-19-2011, 06:13 PM

I consider turbos to be a wear item, after seeing all the failures on these cars. Combine that with extreme temperatures, very high RPMs, oil feed lines, I expect them to fail at some point.

So, I see the concerns of running high boost with stock DP's. I then ask what is considered high boost? Clearly, 19-20 is high but what about 16, 17, or 18? I only ask because these aggressive maps run that high on stage II which states fmic or downpipes required but not necessarily both.

Ps, I know I'm splitting hairs but I like getting feedback.

yea and now the JB4 wont let you until its warm

Actually PROCede started that, and had that feature until the latest maps. I actually think it should have been left in with default set on, and an option to turn it off for those that don't want it. Especially with winter cold upon us. IDK but I suspect its only temporarily disabled since its such a useful feature.

Is this feature offered on COBB?

I agree. The feature is more important than the ability to control the wastegate positioning to prevent rattle before the engine warms up and the Procede's performance settings kick in.
