No, turbochargers don't work well on Bullets.
Have you tried to it before??? if so please share your experience...
Low-revving single cylinder engines can't "spool up" a turbo, because there's to much time between exhaust pulses. It doesn't operate the turbo properly.Secondly, even if you could get the turbo to work somehow, the Bullet cannot withstand the added compression of turbocharging in its hemi chamber, on pump fuel.It would need to be alcohol or nitro-methane, or something like that.And there's no way to run an intercooler, either.Nor is there any way to deal with the ignition timing regulation needed.And if you somehow managed to get over all those obstacles, the bottom end of the engine would blow up from the stress that the turbo would put on it.
Turbo charging any single cylinder engine would be difficult and extremely expensive.The single exhaust pulse does not efficiently spin a turbo. To my knowledge there is no turbo of the right capacity for a Bullet.A belt or gear driven supercharger would be more effective but just as expensive IMHO It will take a lot of research and development at considerable cost as there are many technical obstacles to be overcome. The host engine would require many new parts made specifically for the purpose. Again, to my knowledge there is no super charger of the right capacity for a Bullet. In theory it could be done though.
Thanks for the interesting thread Sid,I am not warm about choppers due to its ugly handling but it sems a well done job! About mounting a turbocharger on a single engine, a 700 cc displacement can make the turbo lag a bit lower but cannot solve the problem of "pulse" .A supercharger "jointed" to the engine through a properly sized "air box" could be better.Some years ago, a tuner called Ivory maked a Yamaha XT 660cc with supercharger which worked realy well, allowing a small batch production of 20 bikes but is quite difficult to find information about its work on the web.In the old period (about the fifties) the famous italian brand MOTO GUZZI used both a single 250cc ad a V twin 500 cc (similar lay-out to a Ducati engine) coupled to a supercharger.The 250 scored some landspeed world records and won several races , it demonstraing the good function of supercharged also with a single engine of medium capacity (if fitted with a pressure-chamber between the intake manifold and the blower).On the opposite, I think the "funny" show-bike with turbo a good object to look but with 40 HP "only" is surely slower as an "atmospheric" tuned Bullet....A blower Bullet can work well but it need to improve all the internals to resist to the big torque given by the blowing action.I hope my English is clear enough... I know engines (and blowers) but don't use my English language since 2002 CheersFabrizio "McDeeb" Di Bella
