I just put on my AEM FUEL RAIL with B&M FUEL PRESSURE REGULATOR with a CHM FUEL GUAGE, I have the fuel pressure set at 38 psi (too high or too low). what my question is that.....has anybody felt a horsepower difference or a quicker throttle response or what? my friend came by and he hit the throttle and he felt a quicker response.......and i said that i cant tell a difference so i drove it and i felt more hp and quicker response :shrug:

IS IT ME OR IS THIS THE SHIT :confused:

Why would this increase anything? Fuel is not the bottle neck in an all-motor setup, it's the incoming charge of air....how about you all focus your attention on that before wasting money on AEM fuel rails, etc which are not cheap. I'd take some of that money and buy a book on engine dynamics, seriously...I'm not being a d**k, I'm being straight up...you will learn where to put your money and focus your attention on. If you view my message and just being a$$hole-ish your ignorant of the truth.

This *****s right true story homie let deez *****s kno wow would you spend money on dat shit wen u can get soem otha shit dat will really increase horsepower with a feeling of da diffrence your imagination makes u feel as if your got got soem balls off of you puttin in a new nut on ur car.

ok one...u 2 are smokin something, 2 just bc u r getting a new fuel rail doesn't mean u r doing it just for HP. i got a new fuel rail and pressure regulator and new whole fuel system. it worth the money....helps not just for daily driving but for shows and just to damn well look good. it is like why the hell would anyone get a body kit? or get new tail lights or carbon fiber hood or a dress up kit..."dude they don't increase hp....save the money for a turbo" lmao. to each his own. but i would say as the rules of science apply.....if u replace anything i mean anything in the engine, on a old ass car, it is gonna be better. as long as it is installed correctly and the time is taken to do it right. so i say go ahead and do whatever u want. if u want to get a fuel rail first go for it. it will be the basis for a nos set up later on, if u wann alook at it that way. so without being a complete asshole, i have said my thing. i hope everyone keeps to his owns plans on building his car. do not let anyone influence u on doing something u really do not want to do. whew hope this sheds some light on the subject

You tell em Cisco... :tu:


BTW The stock fuel rail has been proven to provide more than enough flow to handle 275-300+ hp...

You're more likely to have a need to replace injectors long before having to even think about upgrading the fuel rail...

READ the thread title, hes not asking for your opinion on whether or not he should have gottten a fuel rail. i dont see why people have to flame for no reason, he was asking a simple question, not a paragraph long response to why he shouldnt have gotten a fuel rail :confused: . The fuel rail will help a little bit with engine performance, but in the long run, i doubt you'll see a lot of HP from it. And as said before people mostly use it for looks and show.

lol ok well as i said b4 think of i this way....a almost 15 year old fuel rail...HMMMMMMMMMMMMMMMMMMMMMM...i wonder how crappy the inside is...take your stock one off and take a look at it..it is amazing how dirty it can get. well anyway, even if u r for more HP and just having youre car run better...a NEW fuel rail is a good investment. if will run more EFFICIENTLY, and will handle for HP and more abbuse. Even if u r not going to add NOS or a turbo it is still a good thing to replace. if anyone has taking a physics class or even has the slightest knowledge about cars, they would know a new fuel rail is better no matter what. :evil: ok so maybe 1hp more but it gonna run more efficient and get better gas mileage. ;) o and BTW it is not expensive at all...maybe 100-150. :angry: and that is the more expensive side. ebay...probably 75. well off to working on my car again. :bouncy:

Time for Jay's Spend 'n Save theory of car part purchase.

Spend $3.49 on a can of carb cleaner.
Save the money on a new fuel rail.
Spend the same amount of time on removal/installation.
Save the rest for something worthwhile, like a new fuel filter.
Spend the extra on strippers. :tu:

listen i just wanted to get peoples opinion on this. seeing that many people on this site dont have this part anyway. and yes my motor is all motor :tu: just to let you know. and to my understand that it did make power and good throttle response.

And what motor do you have :confused:

Bumping an old thread to say I installed an AEM rail and regulator today and notice a difference with the pressure set 38psi @ idle.

Around 3000 I feel a little pickup, and my tires break when I step on it from a dead stop.

Definetely 5 hp or more...

Unless my engine was starved before.

:idiots: is all I have to say. Just that. Nothing else, I will not flame you on this one. I just believe that there are better things you can do with your money. BTW, that combo is close to 300. So yes 300 bucks for a butt dynoed 5hp? When you dyno it I bet you get maybe a smoother curve max gain of 3hp and that will occur at the low rpm. I am sure you lost something in around 5k.

I was. The AEM rail and regulator combo do help the engine run smoother but its alot like installing an MSD. They only improve engine setups and free up lost HP. They do not create gains. BTW, the STR fuel rail has a bigger bore and its better suited to racing applications.

When I want gains, I'll install the necessary parts.

I don't need you or anyone else to tell me how to build my car, and call me an idiot for spending my money the way I want.

My car is EXTREMELY reliable, great on gas, handles great and will only improve.

If I wanted a fast car, I'd build one.

The most I'll ever do to this car is maybe a head package for gains.

I like my car the way it is.

And 3 hp wouldn't break my tires.

So unless my stock rail or regulator were inefficient, I felt a significant gain.

When I need all motor help, I have Cisco to consult.

Gains are clearly not my goal right now, its basically medium improvements over driving a stock car.

- Looks
- Gains
- Handling
- Socialization with some of my friends
- Keeping myself occupied

I have the money to buy a fast car.

I'm learning this engine and car, and seeing how things are done.

I'm not losing money doing what I want:

Seriously Tonk, you are too sensitive to constructive criticism. If you want to post about something you did, you are making yourself open to any kinds of comment. That means anything you precieve to be "good" or "bad". I told you from my experience about that. However, how you spend your money on your car is entirely your business personally I really do not care because that's not my problem. As for the daddy comment, I think that was just hilarious.:lol: I was posting from my experience. See, I don't know if you ever built a serious drag warrior before, but I have. And when I see people who want to mod their cars but they don't seem to know where to start I try to point them in the right direction, like I did when you started those "I want more hp threads". If you are that pissed off with my opinions then whatever. Like I said it was constructive criticism. You can take it as an attack on you or take it as a friend's advice.

Referring to me as an idiot is not constructive criticism.

I let that one go...figured it was not worth commenting on. Seriously, money is an issue for most people when it come to tuning cars. I never want to sound like a tool or like I am better than the next when it comes to such matters. Sure, I really can just throw my car in a shop and pay whatever. But, I do not think that is cool, because people will want to do things that I may have done but may not have that in their budget. That is why I prefer to build and do my own stuff and show people it does not take a heap of cash to build an awesome car.

EDIT: I know that says idiots but it not what I use it for. Building a 13 second integra is pretty cool. However its still a street car. I am refering to my 1994 Nissan 300zx. I have it running 10.9 seconds right now and its not running its full potential due to a loss of traction. I been here and there so I know what parts that can provide the power and what parts help maintain the power. Like I said, I share my experience with you people so that you can make educated decisions to better yourself. I am not saying I know everything, but I am willing to share what I know.

what i don't think people realize is that alot of stuff like aem fuel rail and fpr are used later on as well for more extreme mods. take that into consideration ok?????

damn this forum is making me sad....more and more people bashing and forcing others to do things thier way or "your dumb" tis tis tis :angry: :bash: :bs: :nono:

Its not bashing if its guidance. Your dumping a bit more fuel in upon throttle tip in is why you feel a difference in throttle response. Probably something close to a 12.3:1 a/f ratio. By increasing the volume of the fuel rail you've effectively increased the potential amount of fuel that flows through the injectors...but if the injectors are still opening at the same duration there isn't any more fuel going into the cylinders (unless the fuel pressure was raised) but neither would it create more power. Air + fuel creates power. F22's run about a 12.5:1 a/f ratio stock all throughout the powerband. lowering that a/f ratio as you have would actually cause a loss of power because theres no substantial increase of air going into the engine to compensate the fuel. The FPR on the other hand can add about 1-3hp because of the increase of atomized fuel...but a substantial air increase must still be compensated with it. And i'm not just talking an intake.

Honestly, when the guys in this thread said it was a waste of money if you were going for HP they were correct. And i can back it up with technical talk. I have the ability to prove to you scientifically as to why it was an aesthetic purchase and not a power purchase.

If you believe otherwise then dyno it and have your proof on paper. Essentially you could have had the same throttle response with a $20 throttle rotor. But in the end, we're glad your happy with your purchase :tu:

lol i am going for the blue theme personally. it may not have made a big difference with just the fuel rail but entire fuel system omg yes. biggest gain so far. and that is w/o replacing the fuel filter yet too lol yea i should get that done soon. and i agree with the scientific aspects u mentioned. unless fuel pressure is increased, then no additional fuel will be delivered however in my case the venom injectors are 265cc not 240cc so there is some additonal fuel being delivered. i think last time i checked b4 my fp gauge broke was at 40psi. i blindly changed that :( o well seems ot be working well and not rich enough to see or smell. and yes most people get it for the aesthetics but it is a good upgrade in the LONG haul. IMO
