Bosch pump failure?
What are the signs that a Bosch pumps has failed?
I am about to post my dyno (once scanned) for my stage 2+ E55 and something is seriously WRONG with the car.
It is making only 394rwhp/491rwtq with 154 F starting IATs and a peak of 279 F@6000 rpms for an intake charge woth an A/F dropping BELOW 10.0 at redline.
I DO have the Evo cooling upgrade.

E55Baller: You have a Johnson pump. Make sure it is working and there is fluid in the cooling system. Your IAT should be in 140s cooling down to 110s within 10-15 seconds after the run, depending on ambient temperatures.

Vadim,
I will give you a call soon after I post my dyno. Can you PM me your #?
I really want to get my car straightened out.
My IATs after the car was cool (30 minute rest) was 151 F and that was in 86 degree temp with 40% humidity. When I started the car up the IATs jumped immediately to 156 F within 3 seconds and 279 F about 1 minute later at the end of the dyno run.

I know I heard that those Hennessey pulleys are pushing more boost than other tuners.. That's why they claim high improvement in PEAK power. You might be generating waaaayyy too much heat.
Also, check your engine coolant level. What is the engine temp? You might have a faulty water pump.. Water pumps on the E55 are notorious for failure. Check that out soon!
