Whats a better superchrager for road racing, centri or twin-screw?

Well, suspension would be my first upgrade if I was interested in road racing.

centri. that instant torque of a twinscrew would hurt you in lower gears as for as traction.

twinscrew, as you will be in lower rpms for road racing. depending on your gears, you will be in mid 2nd or mid 3rd gear coming out of turns.

I would say a positive displacement, it allows for lateral boost build and flat power curves so you get the most in and out of a curve...however i think what you should look into more is niether...build the engine to be N/A so you dont need the extra weight/maintainence of a supercharger to deal with...besides you shouldnt need more than 500 rwhp to be competitive

He doesn't have a 4v....he wont get more then 350 out of his 2v NA. If I was ever to do an NA build...I would buy a 4v motor and have it built then drop it in.

+1 except i would buy a 351 or ls1

Years of testing has shown that a centri is best suited for the road course. Most prefer the vortech s-trim because of the reliability you get with the better oiling system. During road races you need something that will hold up to the heat. i have seen great traction out of the corners with my car. There is good power down low and its not slower than a twin screw. If anything I would think that its faster because theres better traction.

Even if someone has a car thats putting down 500+ rwhp, traction could be a problem... but good tires and a suspension fixes that to a point. Eventually, I would think a driver mod comes to play. When I've seen road racing, very few guys just romp on the accelerator going thru a turn or whatever. Playing with the throttle would seem to be very key in road racing... knowing how much to get on it at certain points on the track. I don't see where either supercharger would be better if you knew how to drive the car on the course.

I would think either would be fine.. considering on a road race course your going to want to continualy stay in your power band (meaning down shifting a LOT), your very rarely going to be out of centri's boost.. if your shifting at a point where your droping below 3500 RPM, your shifting WAAAAY to damn early.
