Default Supercharging my Street Triple

With the Chappy finished and done with, my dad's bike almost rebuilt, it's time to start on something I promised to do about 5 years ago. Cunningly enough it was my 5 year plan to supercharge the Triumph. I've bought an Aisin AMR500, a roots type blower that displaces 500cc/rev. I'll be running around a 1.7-2:1 ratio, giving me between 5 and 7 psi of boost. The stock fuel system and computer can handle this, according to guys with turbocharged 675s. I plan on making an aluminium plenum chamber, and keeping the stock throttle bodies in their stock position. At the same time I'll remove the head, give it a mild smoothing, and put in a thicker head gasket.

I'm currently thinking of using an electromagnetic clutch from an air conditioning pump to allow me to start the bike without having to turn the supercharger, and I'm actually thinking I could probably use the pulleys from an appropriate a/c unit rather than having custom ones made up. I'm currently on a LAV/Stryker course so I can't upload anything but I'll try and rectify that asap. Do any of the forced induction geniuses here have any pro tips for me? I'm used to FI, but mainly in diesels so I'm not sure on everything. The biggest fear I have for the moment is overboosting on throttle off at high RPM, I'm picking I'll just get a blow off valve to dump excess pressure.

Ps: remind me to show you guys some pictures of the Thunderbird Sport me and dad put together. It's something special.

It's not so bad as long as you can keep the fear from your mind.

Sounds like you're on your way. BOV would certainly prevent overboosting, and it was the first thing to pop into my head too. The only thing I would be careful of is making sure the design of the A/C clutch can handle what you're planning on throwing at it.

Apparently the appropriate supercharger term is bypass valve. They seem pretty cheap and easy to plumb in.

Street Triple. It's an 09, I bought it brand new. The build thread is in my signature. Looking at intercoolers, I think a Toyota MR2 is my best bet. I can get a 395x200x100 intercooler for not very much at all. I'll be re doing my coolant pipes at the same time, using carbon fibre tubes mated to silicone join pipes. I'll do the same with my intercooler pipes.

I'm thinking of changing my compression ratio by installing a thicker base gasket. Could I get away with using gasket paper? I have access to a large amount in many different thicknesses so that's why I'm asking.

i could see a few issues with doing it that way, one of them being gasket squish

to make a paper gasket that thick would mean you have a lot squish so it will be hard to get accurate measurements inside the combustion chamber plus im sure you would have issues with leakage

im sure there is more but someone with more experience than me will have to elaborate

Cometic will make you a metal core gasket in whatever thickness you want. I would go with that once you figure out the thickness you need.

Thanks for the input dudes. I figured gasket squish would be my biggest problem. I'll give Cometic a try once I've done some more calculations

Got the supercharger in today. It's freaking tiny. I can comfortably fit it under the tank, all I really need is a solid mount that includes am outrigger shaft and bearing to get my belt run correct.
