soo i bought me a adjustible fuel pressure regulator and i was wondering if i turn down the fuel suply would i get better gas milage? or would i end up expletivein my car?

That could make you run lean which is very bad in many ways. It will also confuse your ECU, probably increase engine temps and cause a power loss.

For this car?



I see a lot of 5th gen preludes with body kits that smoke

 

iv had friends turn their fuel down and they get good *** gas milage so i thought maybe if i do same mine will get gasmilage and what is the stock psi level for fuel?

OMG dude, they probably have no clue what they are doing. Do they use an A/F gauge and how are they even figuring out what their MPG is?

There are many better ways to get better MPG, mainly driving style/skill and tire pressure.

 

lol well after 135mph my car just eats gas.. unless i barly tap gas peddel im expletive with the fuuel pressure see how it runs if i dont like it ill put the stock one back on it but whats the fuel pressure for stock? and mine has a custom wide body on it stock bumpers dont fit,,

 

Haha, the more frontal area you have the worse MPG you will get. So at 135mph (which is rediculous, F&F FTL) with a wide body kit I am surprised you can't just watch your fuel gauge go down.

Any manual should be able to tell you the stock fuel pressure, but you need to set it the correct way.

 

yeah after 135 the gas gauge just drops n when i hit a bity over 150mph i just tap gas pedel n it gose flyin i put it full throttle it gose no where

150mph...i can tell u care about urself and others haha but in all seriousness its all about the air fuel ratio

 

i do it when im racing its about an hr drive from where i live a boat launch and supras like 2 race til 18mph i top out at 176mph lol!! but yeah im expletive with the adjust fuel press thing n if i dont like it il take it off

 

This does make me wonder about what the ECU would do.

Reducing the fuel pressure would have no immediate closed-loop effects but there would come a point where the O2 sensor won't have any more authority to add fuel, whatever that point would be. Would it throw a code at that point, or just watch the engine melt?

 

im not gouna turn it to much down just like 5-10psi lower then the factory..

What happens when you run out of gas or the fuel pump stops working?? That would be close to the same thing....

Same idea, yeah. That said both those will be over fairly quickly, and I generally get the impression that the ECU takes some amount of time to decide to throw some codes.

But I'm honestly just speculating. I have not turned my fuel pressure down until my engine stopped running

 

first off i think your full of **** running 176 mph and talking about how to save gas. if your doing 176 you have a good deal of work done to your car there for eating up gas no matter what you do. but honestly i dont think your car can hit 176 mph. your asking what a fpr affects are... meaning you dont know to much about your engine. there for you full of **** you prob hit 176 khm

 

lol no i had a fully built motor on a aem ecu now i got a factory ecu and i dont go that fast unless its sundays but when i drive aruond the city i wanna turn my fuel down and on sunday il put it back up... i just need kno how much if psi i can go lower i buitl my h22 motor up tahnk u i spent 2yrs buldin that expletivein motor!

 

so what u got done 2 ur lude? i like it if thats urs the blue one i got mine painted 3times and i stuck with red the 4th time iw as gounna for blue then the guy is like lets out a e4 2008 for color and i liked how it looked so yeah lol!

Your Prelude does not go 176 and you do not know very much about engines. If you did have any of that someone else did it for you.

 

haha yes it dose iv done it with 4ppl in car with me my rpms pass 8500k and it keeps goin iv spent 24k in ma lude

Sure dude. Just give it up now....no one believes you.

Proof or stop posting.

 

il give u prrof come over 2 louisanan and ill take u for a ride or let u talk 2 ma friends at are every ntie ang out we all turbo / all motor waytin for punks 2 show up 2 race

Bahahaha, you have to be kidding. That is awesomely retarded.

Are you 15 at home on your parents computer with Tokyo Drift playing on the TV and hip-hop on the radio?

 

lol you got some jokes... i bought my prelude flodded after katrina hit and i had built it up and get it runin i redid eveyr thing expt dropin a new motor in it but then i started buyin bolt on parts and addins tuff for horespower and the only thing im missin is the adjustible fuel presusre reg so i wanted 2 kno how much i can cut from the psi with out expletivein the motor

 

leave the stock regulator on there unless you have a way to measure the air to fuel ratio and can determine where the most optimal pressure lies.
