It seems that the stock water pump can handle a lot more rpm. Good news for me.
You asked me about my concern. I have no concern, when the pump can handle 6000 x 185 all the time.. :-)
But here we go, example: i was in a hurry today driven from a to b. About 10-15 minutes 4500-5000 on the german autobahn. Just straight not pushing the pedal max to the limit.
you 185 / 100? = 1,85 x 5000 = 9250
stock 154/ 120 = 1,28 x 5000 = 6416
more than 40% overdrive at the waterpump. A little scary.
