Barely used. Comes with carb stud kit installed on the intake, assume the stock calibration for electric choke on the carb.
$250obo each + shipping or I'll do $450 + shipping for the pair.
The carb cheater isn't in the same hemisphere as the sniper or this new Edelbrock system.
You can read my rants in other posts, carb cheater is a vacuum leak that for some reason people think is useful instead of doing the actual work of tuning fuel delivery.
Just another tool in the toolbox, the HV pump will give more hot idle psi without having to stack washers in the spring that will affect the psi at other rpm. A person may or may not want that (nobody needs 80psi going down the road)
Yes, but the pressure relief system must be considered. At hot idle the HV pump isn't going to make enough psi to be on the bypass but it will make more psi than the standard rotor pump because of this principle. At higher rpm, more psi, and pressure the bypass will come into play.
Relevant perhaps, the HV pumps have a longer body for the bigger rotors, are all hp pumps built with those bigger rotors?
A HV pump will aid weak hot idle psi without pumping up drive rpm psi.
