ZX14 supercharger??
Has anyone had any experience with a super charger on the ZX14 engine? I am trying to find out about the pros and cons of these units.
I know that TTS in the UK make a kit for the ZX14 using the Rotrex supercharger, also Procharger seem to have some very neat blowers.

I'm not familiar with them either... I'm curious to what the pros/cons are. Everyone runs a turbo, never seen a supercharged bike at the track..

Well i know the power you do get is full time and instant with a supercharger.

superchargers are crankshaft driven, they produce nearly instantaneous power, especially roots and twin screw or any positive displacement ones for that matter.
The centrifugal ones turn velocity into pressure, and thus must be spinning faster, and overdriven.
Superchargers also create parasitic HP loss as your crank is driving the compressor.
They tend to create less inlet heat than a turbo, but not substantially less.
Oh, and due to the mechanical nature ( pulleys, brakets, plumbing belt, belt guards) vs turbo, they are heavier usually.

I would think it would have to drop a couple compression ratios from stock.

Yes otherwise you'd have to underdrive it so much that you won't have the full benefit of the supercharger.

Yes you'd have to use underdrive pulleys to turn the supercharger slow with high compression. The way to do it is to run lower compression and use the overdrive pulleys and make that blower work!

I had a friend that actually built a supercharger kit, and sold a few of them, for the old Suzuki GSXR 1100, back in the mid 80's. He ended getting his bike on the cover of a major magazine at the time, and if I remember correctly, went 200mph with a supercharged 1255cc kit motor he also built.
The moral of the story was; they were brutally quick, had incredible torque and bottom end, and sounded mean. However, the cost to hp ratio was a bit higher than a turbo.
You also have to remember that someone has to make a kit for the 14. None exist at the moment, and for a very good reason. The economy!! You would need to sell a minimum of 5 or even 10 kits, to recoup your tooling/testing/development costs. And, the first kits would be very expensive.
I doubt they would be any quicker/faster than a turbo, and would probably require more maintenance. It would be nice to have, but realistically, for the money, everyone is going with turbo's because there are a few kits out there to chose from, they've already been tested and proven, and the cost has dropped a bit.
Bottom line; to much work, to much money, to little return on that investment=not anymore hp than a turbo.

Isn't the big Kawasaki Jet-Ski supercharged? Pretty sure its a 12 or 14 based engine.

I have a SeaDoo RXT-X that has a 3 cylinder 1500cc engine with Supercharger. It's also fuel injected. Makes 255hp to the crank. Goes zero to 50 in about 4 seconds, zero to 30 in 2 seconds, and tops out at 71mph on the GPS.
Kawasaki has one that has also has a supercharger on it, and that one puts out 260hp, but weighs a ton. But, your talking about a totally different animal. Watercraft are underload constantly. Bikes need to go on and off load quickly.
As far as dependability, the Kawasaki ski has had a lot of problems with gas in the oil, cause by blow by, so the haven't been the most reliable, and are certainly not the fastest or quickest. But, they are the quickest in rough water.
