i wanted to build a street rideable bike. i can ride around town and never boost until i want too. the reason for this is that i left the secondary throttle plates installed to prevent boost until a higher rpm. boost range is around 8000-12.5k rpm. if you look at the dyno graph you can see max power is generated at 9900 rpm so there is no need to go over that rpm range anyway. once it hits that rpm range the bike goes vertical.....

yes. since i am only using a 1:1 ratio fuel pressure regulator the stock fuel pump can handle it. at 6psi with a 1:1 the fuel pressure climbs to 48psi which the stock pump can handle. the problem with the stock pump is when people use those shitty high rate fmu's that bring the fuel pressure higher than 60psi. i used a 255 and a 190lph pump before and it was a waste of money as it was overkill on a bike.

nice project dude...i love bike turbo projects.....did you buy the exhaust manifold or have someone make it? also when to the secondary butterflies normally open? Good info on the fuel pressure reg. A lot of people normally wind up buying crap they dont need when they do a project like that for the first time.
