Procharger.....

I use to have a D1 on my 340 that was in my convertible many many years ago. Got it from the superchargerstore. An F1 with the proper pulley and engine combo 1,800 hp F2/F3 2,500 up. My motor dynoed at 690 hp with methanol injection that was on a progressive system that worked excellent. I am heavy footed so I hurt many a motor so decided to stick naturally aspirated as much as a miss that whine and holly shitness.
