Also what disk, ring, spring should I use.

Thanks alot!

EDIT: BTW, when I measure the ring, should I measure the inside, or outside diameter?
THanks.

You've been here long enough... why dont you do a search?

EDIT: I searched for 2 seconds and the first post I pulled up read
30lbers:
idleing at 24psi fuel pressure and 60psi fuel pressure at WOT at 5psi.

Sup man.
I konw I know...and I did search...but all I find is either 30lb at 10PSI boost, stock injector with 5 PSI, with with FMU, etc..

But anyhow..>GREAT news.
I got myself a COMPLETE new fuel setup, new hoses, new 6-an fitting, new SFMU, new 30lb injectors..

And guys... I start my car today for about 20 second. LOL...haven't done the DOWNPIPE yet.

I tried...and I want to cry..so happy...it's at 30PSI with no vaccum on the SFMU...SO HAPPY..finally not 55PSI or 60PSI....OH MY GOD.... SO HAPPY!!!

OK ... now I hav eto make this clear.
as ^^^ said above.
24PSI at idle. and 60PSI at WOT (under 5PSI boost)

But how bout Static Pressure?

Also, last time I test drove it, my car goes to 4PSI. but I have a FMIC... is that mean I am boosting higher?

WHat I want to konw is, our engine stock can't go over 9PSI, so if I am going 4PSI now, am I still have 5 more to go? or do I look at the PSI before the intercooler?

THanks!
Gil

P.S. Can't wait, tomtoorw will be sunny, so I will weld my DP to my exhaust...and I AM FINALLY DONE!!!! COMPLETELY!

You are seeing 4psi because you get ~1 psi drop from a fmic.
You are really boosting 4psi. The Wastegate on the other hand thinks that you are boosting 5psi. This is becaues of the pressure loss of the fmic. If you re-route the wastegate vac line to the mani. This should solve the problem. Becuase your wastegate will not see the pressure drop from the fmic.

Sorry I cant help with the other questions.

30 # injectors at 21 psi of fuel at idle. Static doesn't really matter, the disc chooses static if you set idle, or vise versa. Get a boost controller to compensate for that FMIC, and turn it up a little, or do what he said if 5 psi is enough for you. (it's not for me)

yeah....4 PSI is fine for me right now.
And I modified the wastegate to 4PSI...stock is 10PSI...so if I want, I just turn the screw and I can go up and down..and Minimun is 4PSI.

Anyway, I need to know about the tuning of the SMFU, coz I will drive my car TOMORROW!!! cAn't wait.... I just have to finish the DP tomorrow. (Weld it to the exhaust)

THANKS ALOT EVERYONE!

THanks for backing me up! Etx.

Yes....after I finished the DP, and the fuel system, I will set it to 6PSI, or 7PSI.

So, can some people answer some of the questions above?
THanks.

Use the biggest SFMU disc. It does not use a ring. If you get stuttering in boost, you will need to set up a bleed valve.
