Pro boost turbo kit on Inazuma

[Fatmama]

Merry Xmas friends 

Sitting in a garage in Thailand and trying to get a Proboost turbo kit working on a Inazuma 1200 (same set up as blandit 12).

Looking for information on how much fuel pressure should be coming thru the malpassi regulater. 

Currently 0.2 bars fuel pressure at idle. 

Bike kills pistons between 6000 and 7000 rpm (see pics). 

Boost gauge indicates between minus 0.5 bar at idle and 0 bar boost at pistons killing rpm.

Scratching heads. 

Any info and ideas appreciated. 

Cheers and sawasdee krup.

2psi, fit hayabusa pistons (forged) or proper turbo pistons. I also destroyed b12 pistons between the ring lines on my first turbo motor.

@clivegto

Thanks, will do that. 

Project will rest for remaining of these holidays. 

Next holiday new luck, will update what we get with turbo pistons.

And throw that crappy boost gauge away - you don't need to know vacuum and its obviously making boost @ 6-7k revs! Classic detonation + cast piston = scrap metal! You need a decent oil filled, air pressure gauge 0 - 15psi / 0 - 1bar

Boost gauge is a decent glycerin filled one. 

Yeah, boost is obvious, was just tricky to watch gauge, and rev counter on public Thai roads. 

 

Can altering BOV setting reduce max boost or does it just influence turbo spool up time? 

[Gixer1460]

BOV shouldn't make any difference to boost excepting that boost pressurisation has to build again after opening. BOV should only open when vacuum present. So how much boost was it making if not '0' ?

@Gixer1460

OK, thanks. 

Highest boost I seen indicated was just under 0.5 bar at about 6000 rpm. 

According to proboost the kit should produce a maximum of 0.8 bar.

We also killed many b12 pistons, mk2 but rubbish all same. Mk1 hayabusa, will sort the issues! Make sure your fuel return hose is big enough as well. We ended up with an-8 and malpassi spring cut down, Just my previous on last b12 turbo.

Busa pistons ordered. 

Fuel return hose need check up. 

Thanks for info, updates once my mate comes for a visit again with the new pistons.
