it took nearly two years but now its done and all in good working order.
here are some pics if the build and the all important dyno results

awesome. good job. you almost came close to my hp/tq numbers on my 02 gsxr 1000 turbo build. i would love to see some riding video......

i have made some changes to the system recently.. bigger charge pipe and new plenum so i am hoping for some more power i will post results when i get it to the dyno]

what did you do for fueling?

turbosnail

i used a begi and a pc3...works well up to 8 psi

busa4

i used a pc3. whats a begi?

turbosnail

its a rising rate fpr.theoreticaly it can give suitable fuel enrichment without the need for a pc3.but using both means some road testing can be done before the dyno...which is vital for a first turbo project as there is a lot of trial and error

busa4

gotcha. i used a begi(fmu) on my second turbo bike build. for my third turbo bike build i use the stock fuel system and the pc3. got great results with 6 psi boost. 225hp and 125ft.lbs.

thats cool. what bike was your 2nd build..
on the face of things my dyno results look ok but i was running 8 psi and needed water inj and -2 ignition to stop det ...the power off boost was crap aswel.
with my new setup i am hoping for about the same hp but at 5 psi and stock timing.
its all done up and running now so just waiting for some dry weather for a test ride then off to the dyno

both my builds were 02 gsxr 1000's. the fmu build was too much of a hassle and it affected reliability. the second gsxr build i didnt touch the stock fuel system and it made a big difference in power and reliability. ive never had an issue as long as i kept the boost at 6psi or below. any more than that will require upgraded engine internals, upgraded engine computer, upgraded fuel system and an intercooler/meth/water injection. you start to get into the higher priced components. 6psi or less is more than enough to scare the ---- out of you so thats all i build. i didnt do any major timing adjustments on my builds. it was all stock timing except at higher rpm range. i adjusted the timing to 1 degree retard just in case.
