it was on the car when i got it. turbo kit installed just no fuel yet. im not to sure about this.

 

whats wrong with it

 

nothing at all. i just dont know what it needs to be set to or if when it see's boost if it raises psi or anything. i dont know anything about this style of fpr.

 

Well, who makes it ?
Find out the company name, go onto their website, and find out the spec and operation on FPR. Most aftermarket regulators increase 1psi of fuel pressure every 1psi of boost. If no name exists on this FPR, I would not run it with your turbo setup.

 

Looks like a b&m regulator, don't touch it unless you have some kind of idea what you are doing.

 

its a b&m. it makes the stock regulator adjustable. Its fine for the average setup. If you have a fuel pressure gauge on the car adjust it to whatever stock fuel pressure is supposed to be ONLY if its running on stock ecu. Otherwise leave it alone.

If your going to get the vehicle tuned then turn it up to 50 psi with the vacuum line off. 50 psi is a good base pressure as it atomizes the fuel better

 

yeah ive only used Aeromotive fpr's in the past

 

its a b&m, is it a 1:1. im about to order a chipped ecu for some dsm 450s for the time being. after a build ill do to some id 1000s or something

 

No it's not 1:1. There's no boost reference port on the regulator you have. The stock regulator is still under that, but it's been modified.

 

When the intake manifold sees boost, since the FPR vacuum/boost hose is attached to the IM, the FPR will see the same vacuum/boost. That means the diaphragm/orifice needle will be pushed down with the same level of pressure as the intake manifold is seeing. That essentially makes it a 1:1 FPR.

 

x2

Stock regulator is 1:1, the b&m piece just makes it adjustable. Stock regulators are good up to around 400hp range i believe. they only add so much pressure then they stop adding. if you have big injectors on a mild setup thats fine but otherwise you run out of injector quicker

 

need someone to confirm this statement. fact or fiction ?

 

Stock, I believe the fuel pressure is supposed to be 50 something for a B series VTEC. Look in your repair manual or online.

 

i ordered my base tune for dsm450s and at 50psi
