Chris.QCR Posted February 1, 2015 Author Share Posted February 1, 2015 Nah not really sorry mate . Was just about to get right into and then brought a ironhead sportster . So time and money has gone into im that instead . I've picked up a xl175 front end that I'll use to get The Lloyd rolling. Hoping to sell my cb350 soon so will be able to buy a triumph gearbox and start finishing the mounts off and focus on getting the engine running 1 Quote Link to comment Share on other sites More sharing options...

Popular Post Chris.QCR Posted June 1, 2019 Author Popular Post Share Posted June 1, 2019 Jeez 4 years aye. Well my Harley is just about finished and while sharing a sharn with @RUNAMUCKĀ in my shed on friday Bart did what he tries to do with everyone and thats convince them to supercharge everything and turns out I was ready for this preachers words and I spent the rest of the day thinking about how this bike will be very difficult to make road legal so I might as well get into a motorsport so Im gonna build it into a vintageĀ Drag bike. Have always had a soft spot for Engineered to Slides Triumph 500 Drag bike so thats the style direction. Im gonna need Aisin 300 Supercharger. Suitable Carb Mickey Thompson Drag slick Norton Gearbox Than Ill fabricateĀ the rest. Ive also decided that this is perfect bike to learn how to tig weld so Ill also look at purchasing a DC Tig welder and get into that to make Fuel Tanks and Pulley Covers and Manifolds. Should be alot of fun to tinker away on .Ā 12 Quote Link to comment Share on other sites More sharing options...
Chris.QCR Posted June 1, 2019 Author Share Posted June 1, 2019 Also there is another bloke in Ozzy that built a blown SR400 3 Quote Link to comment Share on other sites More sharing options...

RUNAMUCK Posted June 1, 2019 Share Posted June 1, 2019 Yes yes yes. Perhaps oldschool needs a belt driven inlet manifold thread. I'll share some general blower guff wit ya all. the super abridged version is, a four stroke engine breaths half it's swept volume per revolution. (In yourcase, 600 divided by two being 300cc) on an NA engine, on the intake cycle the engine breathes in air at atmospheric pressure. (14.7psi at sea level) A supercharger is just a pump. (techincally so is an engine) By either using a supercharger which displaces more air than the engine, or overdrivingĀ the supercharger to shift more air than the engine displaces, the engine will intake a largerĀ MassĀ of air than it otherwise would. as this air is mixed with fuel, more power is made.Ā Boost, is a term often bandied about. Boost is only a measure of the resistance between the supercharger, and the cylinder of the engine. Things like a very good or very poor flowing intake tract can effect this.Ā Given you have 300cc per rev, and AMR300 driven at 1:1 would net a boost figure of zero. (Assuming your engine has 100% volumetric effeciency, and your supercharger moves it's advertised volume. (no wear and tear/no losses through belt slip etc)Ā If you drove it at double crank speed, youd feeding the engine twice the air it could otherwise take. Would would be a theoretical one bar.Ā Thats an awful lot of boost for such an old engine.Ā So perhaps 1.5 times overdriven would be a safer "starting point" Ā Thats the abridged version.Ā 2 Quote Link to comment Share on other sites More sharing options...
Chris.QCR Posted June 1, 2019 Author Share Posted June 1, 2019 So first question off the bat is 1:1 is in relation to pulley size ? So identical size pulley on motor and blower ? 1 Quote Link to comment Share on other sites More sharing options...
datlow Posted June 1, 2019 Share Posted June 1, 2019 shit yeah, had a few day dreams about adding forced inductionĀ to my cx, one day maybe photo for inspo 1 Quote Link to comment Share on other sites More sharing options...
Truenotch Posted June 1, 2019 Share Posted June 1, 2019 @mark105Ā - still got that AMR supercharger? Quote Link to comment Share on other sites More sharing options...

So identical size pulley on motor and blower ? Yes exactly. so youll want your crank pulley to have 1.5 times the circumference of the pulley on the super charger. 1 Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted June 1, 2019 Share Posted June 1, 2019 @427carguy has/had an AMR500. that would work a treat at a 1:1 ratio. 1 Quote Link to comment Share on other sites More sharing options...
xsinclairx Posted June 2, 2019 Share Posted June 2, 2019 Super exciting build! Always liked supercharged bikesĀ 1 Quote Link to comment Share on other sites More sharing options...
Muncie Posted June 3, 2019 Share Posted June 3, 2019 Run an SU on it. 1 3/4" seems about right on my 600 it just opens as much as it needs to. 3 Quote Link to comment Share on other sites More sharing options...
