Hi Guys
I have a question I have struggled to find the answer on by searching this forum.
How much HP (or exhaust flow) can the stock exhaust system handle with just a 3” catless DP upgrade before the backpressure would cause problems for the turbos or other equipment?
The reason for my question: I have been running TTE550 turbos at max target 21 PSI for 2 000km (1 242 miles) and the axial thrust bearing on one of the turbos is completely worn out. The car has mainly been used as a daily driver forth and back from work. The car has FBO but as mention stock exhaust after the DP’s. The fault analyses I have received is a concern of too high back pressure on exhaust side. When searching it seems like several other people run 550-600 crank hp on just DP upgrade, is this a correct supposition?
Thanks
