Adjustable Fuel Pressure Regulator

Hey fellas.

Last dyno day I noted that my car could use a bit of leaning out.



since that run I have added ported E7 heads, ported HO manifold, thinner head gaskets, 70mm maf and underdrive pullies. I would like to see how much difference these mods have made so am considering a dyno run.

however, to make it worthwhile I might as well get the bastard leaned off a bit while on the dyno. what sort of FPR will i need and where can i get one? i see them on ebay a fair bit, are these approprate? what sort of fittings will i need?

cheers fellas

Re: Adjustable Fuel Pressure Regulator

Yeah that's rich for a 5L, most of them run around the 12:1 with stock FP. You may find the MAF has leaned it out a bit. Usually you only need an AFPR when you are leaning out up high due to mods, not to lean it out.

My first one was a Holley one which lasted a couple of months so stay away from them IMO. I now have a Kirban AFPR and it seems great, most of the US guys swear by them because they have 2 seals so they will not leak. Most other brands out there seem to have their fair share of leaks. Ordering them from the US is your only real option, I haven't found anyone locally who do them for the 5L engine. BTW they bolt in place of the factory reg, can be a real pain to do without removing the uper manifold.

Re: Adjustable Fuel Pressure Regulator

i've looked at a few from Summit..

http://store.summitracing.com/defaul...&Ntt=regulator

the Accel one is my sort of price, but its not economy if it leaks :/

http://store.summitracing.com/defaul...regulator+Ford

the crane one looks the same but is double the price

http://store.summitracing.com/defaul...regulator+Ford

the BBK one would look good with my blue pullies, but is the most expensive of the lot..

http://store.summitracing.com/defaul...regulator+Ford

the Mallory one looks nice, but hard to justify as it is again double the price of the accel model.

Re: Adjustable Fuel Pressure Regulator

I looked at all those brands when I got my second one but just by doing a search on the mustang forums I found they all have some probles with leaking petrol into the vacuum hose/inlet. Even though the chances are low, I went with the Kirban because I couldn't find any noted problems with them and as I said most of the guys swear by them. Here is the link to the kirban one, only $69US and they were happy to ship it over to Australia. http://www.jdsperformance.com/index....em&inmake=ford

Re: Adjustable Fuel Pressure Regulator

For full throttle leaning out, an afpr does help. Because WOT (wide open throttle) fuel maps are set and not altered by O2 sensor info, WOT AF ratios tend to lean out once you have done a number of mods. Adjusting the fuel pressure allows you to control these AF ratio's at WOT. Higher fuel pressure doesn't however change AF ratios under normal driving because that is controlled by the O2 sensors
