Just like the title says, wanted to know how many miles some of the black turbo users have on their stock block without grenading the engine?

 

Installed the Black at 24K and have 43K now - going strong, no problems.

 

If I were to run a Black on the stock block I wouldnt push it much. Keep power at or under 500whp. That'll keep the torque in the low 400's. As the old saying goes..."it's all in the tune"

 

yep just keep the torque down and that's the ticket for the most part. a 3 port helps also so you can control boost curve down low and bypass the boost spike and taper caused by mbc.

 

Is'nt cutting back on timing right at peak boost also a way to reduce torque when running a MBC?

 

10k no issues. tq at 387 later on. The problem is this is safe but not as fun as possible. Mated with a 2.4 or 2.3 will optimize street experience, but until you build the motor keep it below 4 to be safe. If you plan on not ever building the motor id go fp green for response down low

 

What would you say is the max torque to wheels to keep it safer? Another concern I had was I read about the guy whose supposed friend blew his engine because he was loading the engine at low rpm. What would be a safe rpm in 4th or 5th gear to go wot? If I was in 5th gear at about 3500-4000 would that be too low with 380-400 wtq to go wot? I know if I really wanted to get the car moving I would downshift to fourth, but sometimes you just want to pass someone without doing that. I would like to hear your thoughts since you are a highly regarded tuner. I'm going to be installing a dbb black and don't want to grenade the engine.
