turbo or supercharger?

Debating on witch one to get

There are certainly more turbo applications to draw from, many many rider's and tuner's experiences but personally if I were to soup up my Busa or CBX for that matter I'd look into supercharging them.  I've always preferred them in car applications.  Instantaneous oomph, not the slightest spool up time loss.  I realize these days that turbos have gone through a lot of upgrading in operation and longevity so the safe bet would be to go with a turbo with a moderate but adjustable boost.

^^^Agreed 


Put a turbo & a supercharger on your busa!!!

Turbo is slick, and after redegreeing my cams, my boost comes on very low, and is so predictable. I've had superchargers on vehicles, and liked them for coming on low, but after having a turbo on my Busa, I'd say it's perfect! And don't have aftermarket cams, because you won't like how the boost comes on abruptly and at a high rpm due to cam overlap. It's useless and scary as hell!

If the supercharger kits available for motorcycles have been developed to the point that turbos have I would say in a minuit go with the supercharger, while they may be ok I just cannot get behind a setup until it has been repeatedly proven, and to me the superchargers up to this point have not............that all being said if I had the money to take a chance, I would have tried the supercharger instead of the turbo, even though I have mine running like a clock right now...........the big difference in riding/driving like a drag car, for instance is with a blower, you hammer the gas from idle and it instantly trys to run out from under you, with a turbo you hit it from idle and in SOME cases you could have a sandwich waiting for boost and until boost comes in you may as well be on your lawnmower, nearly all the the stage1 kits for bikes have no real turbo lag issue also while I have not ridden a supercharged busa but I have a supercharged Harley, and I got to say that Harley would give a stock busa a real argument up to 130 or 140 or so, now that I've had my say........Get a RCC kit follow his instructions to the letter and enjoy

To add to what Rocketgeezer said I think you're also going to find the turbo kits less expensive if that's a concern.

My supercharged Busa was a one off and it worked very well.
I went down the reliability route rather than outright power, with $20k worth of titanium inside me any off could be lethal.
The biggest issue of taking the pulley drive off the end of the crank is the use of a rotary engine seal, I doesn't work that well and its a weakness.
Kawasaki have done the right thing by taking a gear drive from between the middle two cylinders to drive the blower which is positioned behind the barrels.

Although I've never ridden a turbo bike so can't comment on them, but the instant bang of high power on the throttle from a supercharger has to be experienced. Yet at the same time the bike had glitch free chocolatey thick power from 40mph to max speed in 6th gear.

Rides just like a road bike with lots more power all through the rev range.
Front wheel came up easy on the throttle at any speed even with a 5" stretch and my bulk on it.
It was insane fun. Can't tell you half of the fun.

There was an era when bikes were about being different.
Try a supercharger, be different, have fun.

DAS has it pretty well figured out.

Gorgeous looking bike HOS. My absolute favorite color combination of all Busas.

Another consideration if you decide to go the supercharged route is to pick if you you want to use a centrifugal style or roots type unit. I believe all kits are the former. But Kawasaki is using roots type blowers in their 310 hp jet skis. Could be a fun project. I can attest to absolutely no waiting when hitting the throttle in that application.

Thanks mate 
Yes that blue and black is one of the most popular combos.
