sfmu help please

[tcavenger99]

my boost adjustment screw came out and i lost it . all i have now is a hole were it once was can anyone tell me how to fix this problem.

Take the SFMU off. Go to the hardware store and find a new screw that will fit it..

 

[tcavenger99]

so just block it off

so i should block off the 3 ports on the sfmu. the vac/boost/bleed, correct . or should i run lines to them . and if i run lines to them what lines hook up to them. when i got this sfmu it was used and i never got the instruction manual

Haha I didn't mess with them. Screw in the vacuum port, bleed valve closed, nothing in the boost port. Seems to be functioning just fine...?

Quoting Chris

If I am remembering correctly then Vortech's manual said that the boost port is just to slightly tweak the rising rate. So without it your rising rate will just be set to w/e the size of the disc is.

yup that's how mine is. still wondering exactly what the boost and vacuum screws do...

the car isn't running too smooth over all, and just today something weird happened - practically no power, I can tell i'm not getting any boost. Turbo hiss sounds amazing but it's all escaping somehow. I assumed I blew an IC pipe or coupler off, but the weird part is that everything is still connected securely... I'll look into whatever it is, but honestly I haven't cared much about the car the past couple weeks, just bought an 07 GSXR 600

It was running good though before right?
This is the reason everyone needs a wideband, .
And thats not a very good reason to not care about the car. Even though thats pretty sweet. No offense, just being honest.

Im going to look at my vortech manual and ill post up exactly what it says.

yeah the car was running great before, very strong, on just the 15psi wastegate spring.

I decided to get an MBC and switch back to the old 7psi spring. set the boost only at like 10 or 12 psi just to see how well the mbc controlled the boost, and to see if it helped my spool like some claim. That's when it started acting weird, like a little jumpy at full boost. But I've only driven it like twice with the MBC and lower boost because i've been busy riding the bike. then I just had no boost pressure today. That's it's own issue though, probably escaping around a coupler or something.

haha the bike doesn't mean i don't care about the car anymore, but it is very exciting and more fun since i just got it.

Well it sounds like the MBC is what screwed things up, not the sfmu. So I would say to everyone just to set up the sfmu like Chris has it (its been stated earlier in the thread).
What kind of MBC did you get?
I would say the bike would definatley take your idea of speed to a new level
