eh .. turn up the fuel pressure.

 

reduce the intake flow!

how exactly do you do that?

 

To raise the fuel pressure you need to restrict the return fuel line with something. A tight zip tie around the line should do it. And to get really big backfires on downshifts you can reduce the airflow into the engine which makes it super rich by clogging the intake with something. You can put a towel or a rag in the intake, but make sure its before the air filter so it wont get sucked into the engine!

pmed you.

 

take your o2 sensor out of its place and let it hang in the free air. the engine will think its running super lean and add a ton of fuel.. it will be so rich you can smell the gas.


but making your car run rich is stupid.


if your gona do it the right way to do it is to tune. you can set it to be rich at any rpm you want.

but like i said... its stupid.

ok thanks..umm what about putting a spacer/o2 bung in your cat and putting the o2 sensor on. i mean if i take the o2 sensor out and later on my car runs rich and if i put my o2 sensor back on wont the car stop running rich?

Are you freaking serious?

 

is this guy being serious?? Why would you do such a thing??

 

ok look people sorry i didnt mention a full detail story. my friend wants to run rich on his gsr because for some reason he is running toooooooo lean. he has i/h/e/testpipe and my gsr with only intake/testpipe puts about 2-3 cars on him and we are both equal drivers. so please dont get all crazy on me!!!!!!!

 

by product of combustion is h2o
edit: sorry i must be seeing things, but i swear you said when you hold your hand to his tailpipe it gets wet?

that was actually on my friends rsx. thats why i took that part out.

 

ok lol i thought i was tripping. well you could tell him to get an aftermarket fuel pressure regulator.. better than restricting air flow

 

well since he is a full time student and only works about 10 hrs a week..he doesnt have much $ and hes wondering if megan racing is any good since its only $50.00 on this site..

B&M, I doubt is much more then $50.

And the adjustable FPR, I would Think, is the easiest way to run rich.

 

the B&M is a tried and true part

just purchase that and a fuel pressure guage and turn the fuel pressure up until the car runs stoich

 

so you just install the FPG and you can turn up the pressure and your car will run rich...its that simple where you just install it and raise the pressure....

 

with the FPR it allows you to regulate the fuel pressue by adjusting how much pressure the valve requires before it will open releasing excess fuel into the fuel return line

thanks

 

How do you know hes running lean? Running rich isn't going to make him faster, if he really is running lean, there is a problem that needs to be fixed.
