well i have a fuel return system in my car and no problems but i dont know how much more power just doing that would do.
chad

 

Well, don't think just having a return fuel system will do anything for power, but at least it'll allow more aggressive tuning...

 

how do you plan on making it into a fuel reurn system anyways, just curious on how you plan on doing it to see if its anyway like i did mine.
chad

 

why do u have a turbo timer anyways?
chad

 

I really don't see how this would make a lick of difference with respect to advancing ignition timing. Am I missing something here?

 

can someone fully explain your fuel return system and what ya'll used to make it happen

Yeah, curious about that too. Chad?

 

I had one on my EP before I went back to stock. It was how CN was doing their cars before Guardian was out.

 

i just ran another fuel line from the nipple at the bottom of the fpr on the itbs ran it under the car right next to the other lines all the way back to the tank, drilled a hole on the top of the pump housing then took a bolt bout 3 inches long drilled a hole on the top and then one through the middle just like the bolts on the brakes. we did it like that because i was in hurry to get it done and we couldnt find the right size at the store and we have a drill press so it was easy, then just slid the bolt throught the o ring side of the fuel line and dripped it into the top of the housing with a lock washer and bolt tightened it up and put it in.. there is a lil peice of hose ther becuase we snapped the line but that works fine..

 

Chad,

Is there a reason for a certain setup that you would need a return fuel system?? Or will returnless work fine for an application such as this as well??

Just something I am not sure about, it would be cool if you could clear it up for me.


Thanks in advance.

 

Not that i know of. TWM says that for peak performance out of the ITBS you would want to use a fuel return system. WE were going to just eliminate it, but the highly discouraged us from that so we put it in. They said there is a higher risk of vapor lock without it, but that wont accur unless its super damn hot dont know the correct temp off hand but i dont see how that could happen so we just played it safe and did it. As far as tuning I have no clue what the kid is talking bout and how it would help. And i still want to know why he has a turbo timer in his car if he is doing all motor, unless he just likes to let it chill for a while and warm down. who knows.

sorry cant give you really and details or straight answer, i just dont know

Thats cool, it was more than i knew.

 

Cool, thanks Chad!

EvilXkid just posted in another thread that he did not use a return line. I'll eventually ask Lance at Hayward, if someone doesn't beat me to it.

My buddy has a fuel setup like that on a k20 Turbo (03) civic. Good stuff :thumbsup:

 

Sorry for the tardy reply...

Same things happened month's ago when I first posted my setup. Nobody really believed what I did to my car until I posted up the photos. Anyway, the turbo timer is just there for the heck of it. Doesn't serve any purpose.

I'm not a DIY guy, so someone's gonna do this for me. As I understand it, they'd use a fuel rail and injectors and run fuel lines to and from the fuel tank at the back. Don't know the details yet.

And as I understand it, the fuel system on the K20A is returnless. So the amount of fuel supplied is exactly enough at a constant pressure. The apparent advantage of using a return fuel system allows more fuel to be supplied at a variable fuel pressure when it is required. Think this increases the safety margin, so the engine will never be starved of the fuel it requires.

Let me know what you think...

Oh, and, I don't appreciate being labelled a kid. I'm almost 30, and I'm not here to put my neck out for nothing. I need constructive opinions.

hey MbmC, im trying to figure out whether you are f/i or n/a...

anyways where did you get your f-con vpro from? where did you get it tuned?

 

HKS f-con vpro can only be tuned by HKS authorized dealer, so for him it could be Fong Fui Garage R

Not the VPro...SZ. And yeah, Darkangel is right, from garage R. Think they're the only pro shop in town.

I'm running N/A. Turbo timer's for fun.

My car only dyno'd a 209 at the wheels recently. That's why all these concerns popped up. I'm wondering how much more can be squeezed out of the motor. The tuners feel that this is reasonable enough with reliability built in and an adequate safety margin.

Question is, how much is too much? and how do you know that?

 

In a NA car it is called an Auto Timer... and it does serve a purpose if you are driving your car hard.
