The car deff runs better without the pulsing. Timing went up and KR went down.

yes, but now your atomization and flow is much less. Dont get me wrong, that may work great in your application, but in some cases perhaps not.Bflaker said:When mine was pulsing I did some research and found all you had to do was crank down the pressure switch on top of the pump. Its a very small allen head screw. I did that and my pulsing went away also.
If you want to run 100% meth all the time your pump needs the following. The seals can strech with 100% methanol over time. You must have a pump with buna-n valves and the Geolast diaphragm they are 100% resistant to methanol. Viton valve are not.bnice01 said:Cause my pump failed yesterday. It was either running pure meth or running it wide open like that for 7+ months. Meth was in the motor when I took it apart and it would not suck anything threw the inlet portion. I just order another 60 psi pump and bought a 100 psi pressure switch. The valves in the 8000 series pump could not do pure meth but 50/50 would be ok.
