Does anyone know where I can get a 1:1 fuel pressure regulator and what brand is reputable??? Or even a 2:1 would be better. All I can get my S-FMU down to is a 3:1 ratio and my fuel pressure goes threw the roof at 26psi :nono

Regulator # 13109 is adjustable from 30 to 70 PSI. It features (2) Inlet ports and (1) Return port and a 1/8" NPT gauge port. Alcohol compatible. Reference boost and increase fuel pressure on a 1:1 ratio from forced air induction

maybe we could get a group buy goin, i know there must be more people who need a 1:1 at this point.

Call Hahn, they'll set you up with a 1:1, stage 4 and 5 trim should consist of their bosch unit still i think.

Greg (992GNT) had one for sale for quite a while. You might try to hit him up and see if he's still got it.

the one hrc sells is just a boch one. you could probably pick up the saem one at napa for far less than the 140 hrc wants..

so when using a 1:1 what size injectors you running?

I use a paxton efi adjustable fuel pressure regulator. they can b bought just about anywhere. do a search on google for "paxton" and "regulator" and it should come up. it's a VERY dendable piece and always has rock solid pressure in relation to boost or vacuum.

Armond, when would someone like me want to get rid of their bosch and get the paxton your running? Personal preference? Mine seems to do the job, I just havent heard much on the paxton efi

supposedly I run a 1:1 regulator. I run a magna flow. I havent had any problems with this unit and we (houston 2gnt) didnt think it was going to work. But under boost I am at the same fuel pressure as dino with his sfmu. I paid around 160 for the regulator and in my opinoin it was well worth it. If you need, hit me up at my shop Clear lake speed 2814880371 ask for mike. late mike

okay what size injectors do you run with the 1:1 and anybody know anything about AEM's FP regulator?
thanks
james

I run 370's but I think they are a little small i might move up to the 440 range soon. late mike

I run RC 720's. I would reccomend upgrading to the paxton if you want more fuel flow (i.e. once you start making over about 500 hp, it becomes necessary......I don't even make that much power.......yet). I would also reccomend upgrading your fuel pump system and fuel rail beforehand 'though. The best thing I like abotu the paxton regulator is it is all billet aluminum, inside and outside. no paper diaphrams that can go bad, and it has ports for up to 10AN fittings (oh yeah, the base pressure is adjustable too)

I have an SX.. it's the shit! And it only cost 145.00 (of course I didn't pay that much) brand spankin new. You need to upgrade to steel braided fuel lines with earl an fittings. Has a 1/8npt gauge port also for a B&M gauge.

625cc injectors. I have the Bosch 1:1 and it works well for me, so far.

I do have a Bosch 1:1 fpr for sale. Never used, $100 shipped.

you got mail.
