I have an old 30' 79 scarab. Two 540ci. bbc., TRS no steps, 5800rpm, hdromotive 26 quad round ear props. We consistantly see 90 . No blowers for me.

guy at procharger said no computer work had to be done on the twin 350's true or not true

it is not required but will help it run cleaner and more efficient. Mine ran cleaner after the procharger install then it did stock. Mark at percision marin did both of mine.

hi there I saw you put prochargers on 350 how much hp now and what is the fuel consumption .

best regards,
ivan

I have a set for 350 small block's if you are interested

Dears,
