Is a 45 PSI ShurFlo pump enough for a DIY Alky set up or do I need the 100 PSI ???
 
You will need the 100psi one since 45psi of Alky while running 25psi of boost will only give you 20psi at the nozzle which will not atomize it nearly enough. HTH
 
Well... actually the 60 PSI Shureflo is all we use. we just crank down on the pressure screw on top of the pump and make them 100 PSI shureflows..

Lots of cars run with the 60 PSI setting and are happy. it all depends on your performance level expectations. And the sizing of nozzles. See 100 PSI and a big jet will drown the motor. Consequently at 60 PSI and the same jet may do the trick just fine.

Yes bigger pressure is great given the correct nozzles.. what size for you car.. this will require some trial and error.

Convenience and features dictate $$$. Alcohol injection can be simple to complex. If I had a really modded car, I wouldnt go the simple route. On a stock car with mild needs..sure.

Remember, this detonation control device can be turned into a save your motor device given the rite design ;)
