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.
