Fuel Pressure Regulators

[k]

sharpxmen, are you still making the adjustable FPR's?  Will be intrested in one shortly.  Plan to install the Bosch 0-280-150-943 injectors soon and will need one to keep up.  Thanks

i have enough to make couple more so whenever you decide let me know.

Does the adj. FPR only change your WOT(vac removed) fuel pressure?  So instead of 31psi Idle & 39psi vac removed it would be 31psi and say 43psi? or does it increase it 4psi across the board? (assuming a 4psi adjustment) 35/43?

Thanks

its going to increase across the board

cool. , makes sense.
with a 62mm tb, intake matched and ignition upgrade, oem exhaust....  probably start with ~2psi increase and go from there?
or is there really no general guidline?

2 psi will barely make any difference, you can safely go with +4 psi. keep in mind that once the computer re-learns the trims you'll only see an AFR increase at wot or close to that (in open loop to be more specific), so it doesn't matter that you have 35psi at idle or with the throttle partially open having 39 instead of 35, the AFR will still be 14.7 (i'm drawing a blank, i hope i got the stoichiometric AFR correct at 14.7) due to O2 sensor feedback to the PCM (closed loop operation) - which is ultimately what you want unless you run forced induction.

sharpxmen, I bought one of these from you before for my stroker. I am building another stroker for the wifes heep and I was wondering if you still have the parts to build another one?

Thanks, Chas

sorry man, none at the moment and not sure if or when will have more.

How's your stroker running?

Honestly I am still in the ground up process, so I have not even had it running yet, but someday soon I hope :)

Are fuel pressure regulators a fairly standard size (given they look the same).  Found this on ebay. http://www.ebay.com/itm/380315270666?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649
Was wondering if it would do something similar to sharpxmen's regulator mod.  Not trying to step on toes, but may be a viable alternative.  Any thoughts?

Unfortunately they are not standardized across the board.

you're not stepping on any toes, i don't make them at the moment so if you find something that works feel free to post it. This particular one i don't think it will fit, there are some that can be used with a plug where the stock one goes but i have not seen a bolt on solution other than the hesco ones (which is basically the same as stock but with a screw at the end and a disc inside to press onto the spring, same idea with the ones i was making).
