I have a vmp triple pass he with fans, a moroso combination coolant/he tank and a 13/14 pump. Over 997whp thru an auto trans under 115 iat2 on a dyno pull, under 130iat2 on a 150mph quarter mile pass at 22.5 psi. No ice just run pump n fans between passes. I did notice some aeration when switching to the bigger pump but it was easily cured by upping the water level of the tank.
It would be interesting to put a go-pro at the liquid level just outside that I/C reservoir and see what the fluid does when you are putting the 997whp to work in a 1/4 mile sprint. I'll bet the fluid is forced to the back of the tank and there is no telling what is happening with the air (also in that tank)?
