Turbo BP lifespan/ track hours before rebuild
Turbo BP lifespan/ track hours before rebuild
Im curious how many track hours people expect to get out of a turbo bp built engine. I understand there's a million factors that go into that.
my cars built motor with all proper cooling
1.8 Turbo, 7200 factory redline, 10 psi currently for track days.

Durability. An SCCA Runoffs engine might only be expected to make max power/not burn oil for about 10-20hrs of track time. For HPDE, daily driver, NASA racer, autocross.. we like to use 100hrs as a starting point. That is full load, high rpm max duty cycle thrashing. Street driving is something like 50 street hrs to 1 track hr. A bone stock OEM rebuild will easily last 100hrs for HPDE, running the OEM redline assuming good oil/coolant temps. Over rev it to 8200 once or twice though and.. kaboom. Bump that 7000rpm redline with a programmable ECU or add F/I and the life span drops immediately unless you improve the engine and its support systems. Overall, adding rpm always reduces engine service life. This can be mitigated by building a more robust engine and improved support systems like reroute, oil cooler, better quality oil, etc. Nothing wrong with extra insurance if it is in the budget

Thanks for the info! Makes sense. I already have big oil cooler, reroute, and watch temps on track.
When I Hit 100 hours of track time, what do you suggest doing? Taking the engine apart to analyze?

Huge variables for a turbo though.
Quality of tune
gas or E85
OEM or aftermarket bearings
oil pressure
oil temps
oil viscosity
change intervals (OCI)
max coolant temps
EGT's (tune)
