Has anyone tried sticking a roots/TVS or lysholm screw to the top or side of a rocket engine? I'm guessing due to the impracticality of the placement that no one has. What would be the advantages of a centrifugal blower over positive displacement supercharging?

Here is a good article explaining the advantages and disadvantages of te two type of superchargers and turbo. for all around driveability I see why people choose centrifugal verses roots especially on bikes with limited traction. Good question dude it made for a good sunday mornin read.

If you saw the intro thread of mine (don't blame you if you didn't, I never check the **** things either), you would see I plan on putting a rocket engine in a clubman kit car, eliminating the traction problem and positioning problem of a PP SC.

The way I see it is 4psi across the rev range is significantly more usable on road and hill driving than waiting for a mad rush at the end that may be pushing up towards 8psi a la a centrifugal blower or aerocharger. The main problem I see is the extra torque that would be placed on the crank at idle, making it a ticking timebomb. Not to mention the imminent destruction of 1st and 2nd gears.
 
Beautiful. Is that stock or aftermarket?

OEM forged crank, Its not mine I have two friends that this ha shappend to. I have had great luck with mine but its a Rotrex unit with 11.8:1 forged pistons and Crower forged rods.

Detonation can be unhealthy:eek:
 
Just slightly unhealthy. Forged rather than cut from billet? Do you know what steel yours are?
