ok so i'm getting the itch to pulley down again but I am already pushing it for fuel so I think I'm going to go with zzp's BRFPS (boost reference fuel pressure system). I was wondering if anyone has tried it or how far I could drop the pulley after?

Switch to premium pump gas or 100 octane unleaded race gas then pulley down you wont have to push out as much fuel if you switch from e85 and you may possibly want to go with a single pass or dual pass with option b setup.

The benefit is reliability and consistency. All cylinders should be getting equal fuel as opposed to the stock returnless style system. OTTP's is only like ~$375 and it is available now.

There is plenty of benefits for it.... no number 4 starvation... plus with E85 you need a helluva lot more fuel than with pump gas.
OTTP's kit is tried and proven on a ton of cars... all making well over 350+ whp... and all still driving!

hey I am just repeating what is directly on their site. just doesn't seem logical if there is no benefit to spend even more money i'm sure almost everyone knows what i mean there. plus I like zzp better then ottp I have had problems with ottp in the past and I would rather just avoid another problem so I will stick to what has never failed me which is zzp.

Several people have listed the benefits. You won't get more 'performance' out of a properly fueled setup by using another proper fuel setup. You can however get increased reliablility out of the system however if one is able to provide a more constant flow. There are lots of things that will 'work' and lots of things that are 'safer'. My votes on the return style.

I was just curious to my understanding the only difference is that the fuel returns the biggest improvement is that the fuel psi is increased which both do so this is why I don't understand what the difference is and was hoping for someone to shed some light.

I think im going to try it and if I dont like it just buy the extra fuel line and make it into a return style. Its not like I am going to need tons more of fuel. Im in the same boat as you. I just want to run a 2.7 or 2.75" and be able to rev to 7200.

I think the problem with old #4 is cooling related which was one of changes made with the Gen II ecotec block.
It seems like #1 likes to go first on the LNF with an entirely different fuel system but what do I know?
<sarcasm>
#1 must be getting starved of fuel!

Oh. And here is a good thread.
