Well at redline with the pulleys it would be at or over the 20k rpm max for the Unit. Which shouldn’t be a big deal for a moment but I was trying to hold 85mph on a long Steep grade for about 3 or 4 miles. Usually the car sits very low in the rpms because there is plenty of power down low. I never redline the thing. So I guess I pretty much blame myself for not pulling over and restarting the car to get the boost back. I was just in a hurry and needed to get to my destination and ignored the limp mode not linking the high rpm to a potential problem. I think with the two pulleys and the tune there is no chance of running it too hot under normal driving circumstances. I found myself in a very odd loophole to that rule. That being said I am probably going to install a bigger Bosch auxiliary water pump to get more flow through the intercoolers.
