Currently thinking of getting a fuel pressure reg but dunno which 1 to get! seen the FSE on ebay but also seen SARD 1s which is best

cheers Josh

i have a sard one myself and cant fault it.both do the same job and are a good brand name so whichever one ya want really.

 

[dac69er]

the sard looks a bit nicer and it a bit smaller so is easier to fint a place to mount it.

like mike said, not much in it. go with whatever you want.

 

[Joshima]

cheers guys qot pressure r u running

 

[dantheman]

go for the sard. 2.4bar is stock fuel pressure (you'll need to change it depending on your spec/tuner)

 

[Joshima]

currently got an induction kit hks actuator n a decat so wot wud u reccomend?

 

[dantheman]

what boost you running? every cars different mate best bet is to get it checked on a dyno, but if your running stock boost then you shouldnt need to touch the fuel pressure

 

[dac69er]

go for the sard. 2.4bar is stock fuel pressure

this has never been proven. i personally think it is higher than this

 

[Joshima]

got it set 2 0.8

45psi (3.1bar) is the fuel pressure used in 99% of Toyotas.

 

[dave-izzle]

have a rising rate FSE one if you require!

Sard without a doubt, the FSE ones are cheap for a reason, lost count of the number of supra's they have ruined..

and the fuel pressure will be different on every car due to what its requirements are.. you need to get it set up properly and not use a pressure that someone else has mentioned..

cheers

Erm, no, you have it backwards.
Fuel pressure should always be constant and should be set to whats recommended for the injectors (as i said, 45PSI for Toyotas).

If your playing with fuel pressure to tune a car, your going about it the wrong way... you should be adjusting the fuel mapping in the ECU.

Rising rate FPR's are a cheap and nasty way of tuning.

no youve got the wrong end of the stick lol,

where did i say tune it on an fpr? have it set up on an fpr and then fine trim it with your chosen fuel controller..

so am i going to run 45psi on my 550's :homer:

 

[Joshima]

so wot u recommend i do next then? i want to b looking at 200 ponys overall jus dunno where to start! like i said iv got a hks actuator induction kit decat n a back box so wot wud b the next fing to do cheers

 

[dave-izzle]

if you want 200, you need to upgrade your turbo

 

[Joshima]

i no iv been looking at hybrids but sum1 told me if u up the boost u will hav u up the fuel pressure aswel so thats y is woz looking a a pressure reg now

 

[gttuning-glenn]

have a rising rate FSE one if you require!

how much would you want for this?

 

[Fishy89GT]

i no iv been looking at hybrids but sum1 told me if u up the boost u will hav u up the fuel pressure aswel so thats y is woz looking a a pressure reg now

well yes if your raising the boost above fuel cut, as the ecu does not know how to fuel above 0.8 bar / 4.2v

 

[Joshima]

i thought sum1 said fuel cut was at 1 bar
