We are a company in Europe that repaires turbochargers for all kinds of vehicles.
At the moment we are working on a project to turbocharge our own ATV.
Everything has been installed to turbocharge it.(turbo,header,intercooler,exhaust,...)
Are we going to need a small low pressure fuel pump
Andare we going to need a fuel pressure regulator
What about the carb.
Anyonenow where i can get these parts
The ATV is a Yamaha Warrior 350cc 4-stroke. , 1cilinder
I know that the Yamaha XJ650 is a turbocharged motorbike with a pressurized Mikuni on it.
Cananyone help me out here
Get a electric from an automobile,lots of small ones out there.It will need to put out at least 3 psi more than your highest boost.Need a boost referenced return style regulator,Mallory offers some.I just bought a new one for less than 100.00,# was a MAL 4307M.The regulator will keep your fuel pressure 3 psi above your boost so your float bowl does not run dry under boost.
Carbs from XJ are probably too small for your motor as it took 4 of them to feed 650cc.If you run your carb vent lines to boost signal the float bowl will see boost pressure instead of atmospheric and feed fuel under these conditions.I am using a Mikuni HRS 42 with good results.If you use a CV type carb the cv slide will have to see the boost signal also.
