2002 v6 camaro powerdyne kit form rk sport

[2002 v6 camaro uncharged]

hi my name is steve and i am new here,

i was hoping someone could help me with a problem i am having. i wanted to install the 99-2002 rk sport supercharger kit but they tell me that it only works on 2002 camaros that were manufactured up to june 2001 because after june chevy went from a high pressure fuel system to a low pressure system. i have checked and found out that the fuel pump is the same and the fuel injectors are the same and that the 2002 calls for 2 different fuel regulators. i don't know if that is the only difference between the two fuel systems or are the fuel lines different sizes. i was also wondering if anybody knows the reliabilty of putting one of these on the car because i take a lot of long trips and i would like to know if the supercharger would handle a long trip and how much do they affect gas mileage. if anybody could help me clear this delema i am having up i would greatly appreciate it.
thank you

That's news to me, about the 2 different fuel pressures... But if they list 2 different fpr's, then sounds legit.

Anybody know the difference in the fuel psi?

Lines should still be the same size. They are between the v6 and v8 cars, and they run different pressures. (not counting the part about the v8 not having a return line...)

Oh yeah, welcome! :D

i would think you could just upgrade your fuelpump and you would be fine, but i have never heard this before. have you already bought it?

[2002 v6 camaro uncharged]

no, i have not bought it yet because when i called rk sport to ask some questions about it they told me it would not work on my car because it had the low pressure fuel system. i have been trying to find out for three weeks what the difference is. i have tried calling chevy dealers
and they have been no help either they are lazy or really don't know. the only thing they did confirm is the change in fuel systems even though they could not tell me what the difference was

[njp98]

Did they happen to tell you how low the pressure was? My fuel pressure gauge has been showing like 18-22 psi at idle and I thought it was broken, we're in the process of trying to get a screwin FP gauge. Now I'm wondering since my car is a 2001 (maybe after the cutoff) it might have this low preasure system.

[2002 v6 camaro uncharged]

No, rk sport didn't no what the difference between the fuel systems were except that one was high and one was low pressure. According to rk sport as long as your manufacture date is june 2001 or older you have the high pressure system. But, that is for camaros i don't know if they changed the firebirds at the same time or even at all. If you call rk sport they can probably tell you.

The build date on my 2002 Camaro's door label is 12/01. I checked the fuel pressure tonight with my rather crummy gage. Idle about 40 something PSI, with positive pressure on the FMU line the pressure jumps to about 80. My car was bought new and the fuel pump & injectors are stock. I like my Powerdyne, I say CHARGE IT... [img]graemlins/burnout.gif[/img]

Did you get your powerdyne from rk sport and what modifications did you have to make for install. Rk Sport's kit includes a bigger fuel pump and timing retard. How much does it affect your gas mileage. i appreciate the info thanks.

My kit was used and looks older, like it might have been a prototype. The kit did not include a fuel pump or timing retard so I use the stock fuel system with a FMU. I modified the throttle body to prevent pressurization of the crankcase and added a breather to the oil filler cap. I did the JohnD wrap for the belt routing (highly recommend)and also changed the Powerdyne pully to an improved 'grooved' design from ASP racing. The JD wrap requires some modification to the oil filter adapter casting for clearance. The plugs were changed to a colder range and regapped, I now run premium fuel. I also decided to use my cold air intake instead of a cone filter underhood. I left the honeycomb screen in the front of the TB in place. A low restriction exhaust is recommended, in my case I only changed the muffler. I don't race the car and it's not been to the track so I don't have any time improvement to share. I can tell you the difference in driving satisfaction over stock is dramatic [img]smile.gif[/img] As far as mileage I think it wil vary depending on how the car is driven. In my case I'm getting about the same as my daily driver (Olds Aurora) 17 city, 27 hwy.

I feel stupid for asking this but i am new at working on fuel injection systems i have only worked on older cars with carburation until now. What is the FMU and what does it do and also what modification to the throttle body did you have to do. Thanks a lot for all the info.

I'm not an authority on FI by any means. As I understand it when an engine is supercharged it requires a lot more fuel under boost conditions. The FMU (fuel management unit) senses when the engine is at boost and restricts the fuel return causing the fuel pressure to rise to the injectors. Keep in mind there are folks on this board now working with tuning software that might eliminate the need for an FMU and a retard unit, by changing to larger injectors and proper tuning of the engine computer. The TB modification has been covered in many threads, you may want to search for more info, basically you remove the TB and block a hole with a slender pipe plug, it's a fairly easy task.

just curious (dont mean to sway you one way or the other) but why are you interested in the Powerdyne kit? Do you know about the Turbo kit? If you dont then please read the first post in this thread http://www.camarov6.com/ubb/ultimate...4;t=001883;p=1 it should help you out. Either system you decide on though you need to get this whole fuel system iron'd out.

[2002 v6 camaro uncharged]

I am interested in the powerdyne kit because i wanted something that would work with my current mods like my ram air induction system, my headers, jet chip, etc. My friends have told me i should get a supercharger instead of turbo because of the turbo lag and with my driving style and needs i feel i would be better off with having my boost come in the lower rpms. But, i am still looking and researching and i will defintely look at that post you sent me. All this research and trying to figure out my fuel system is starting to give me a headach, it has even made me think about swapping engines but i am sure that wouldn't any easier.

Keep up your research but turbo lag is highly overrated. Turbo cars on this board are putting down better #'s and times than the cars with just the powerdyne unit, just an FYI. Read the whole other post and you will see the good and the bad about each system. Also the ram air is really not much if any help with FI. And the Headers (if they are pacesetter) can be used with a slightly moddified kit from tiago (which i beleive he modifies before he sends it out). Good luck with either system, they both have good and bad.
