what is a good fuel regulator to support 800 hp motor dead head style none return
thanks

Aeromotive 13201 is good to 750hp, don’t know if they make one that will handle 800hp.

I bought one of Robb's dual mode regulators way back in the early 2000's.
I ran it a couple years in dead-head mode in my other car before switching to injected alcohol.
Well it sat in the box for years until I bought my Daytona and so I put it in this car. I decided to use it in return mode (plunger swap).

Good to know he is still in business, I may buy a new diaphragm to have on the shelf for the future.

This regulator will support over 800 hp. I had this regulator along w/ the little Aeromotive street rod pump on my car running 9.50s at 140 mph at 3800 lbs. Dead head system w/ -8 line.
