  • Fuel System Plan?

    For my build im going to get these injectors

    http://www.racetronix.biz/itemdesc.a...114992&eq=&Tp=

    they will work fine right? what will they be rated on out fuel rails?

    Also which exact fuel pump should i use?

    and im going to be getting a boost a pump too.

    Sound Good? Any Advice?

    They look like the 65lbers I have in my 96' Camaro so they should work, I didn't see if they were bosch style connectors, I don't know what the rating would be never heard of them before , but it usually 5-10 lbs lower on our system. You might look at ZZP's 65lbers. A walbro 255 will handle your boost needs, look for the high flow Walbro thats what ai have and its suppose to keep pressure up longer than a reg. walbro. Boost a pump is up to you , I just used Caspers voltage booster which at WOT gives a extra 2 volts , and it was about $70 just have to modify it just alittle to work on our cars. Go now my son and let the turbo gods bless you. LOL

      last part was funny XD you think the 65lbers will be way enough for my build. And if i buy the voltage booster could you help me with the install

        The voltage booster is easy , just the plug in for the ALT. needs the little plastic piece dremeled down so it fits the connector, I emailed Casper's and told them but they never answered me back. You could try the 65lbers, or try the ones you posted, I just never heard of them so I don't know if they would work or not.

          alright well the 65lbers in your own opinion should be enough knowing my build right?

            If your going for over 500wrhp you'll need 2 walbro's and 120lb injectors. But if going for over 400 wrhp the 65lb injectors and a high flow walbro would be fine.

                  They are the same injectors that ZZP sells.

                  Most of the popular aftermarket pumps are "high pressure".

                  If your going for over 500wrhp you'll need 2 walbro's and 120lb injectors. But if going for over 400 wrhp the 65lb injectors and a high flow walbro would be fine.
                  That simply isn't true. A walbro with a proper hotwire kit should be good to around 550whp. I make 400whp on 42#'s, a Racetronix pump and rewire.

                  For 500whp the injectors you posted will be more than enough. To support 500whp (575bhp) all you need is a 72#. But the siemens injectors are fast enough it doesn't matter.

                    If you look at what others have done with high 20+ boost , their running dual pumps like Linx setup or Vipers set up Linx went with 120lb injectors and Viper went with 65lbers a 1:1 fmu to raise fuel PSI. Because at their level of PSI and boost was the most have done with their systems. They were showing fuel PSI dropping at a certain point so adding more fuel was the solution. Thy both ran dual fuel pumps for their systems. Walbro makes a high pressure pump that is rated higher than their reg. pump , it flows more at higher PSI.

                      so those injectors will work for the 96 fuel rail right?

                      How do you install two fuel pumps? Is their a write up?

                          Re: Fuel System Plan?

                          Depends on how much boost you plan on running, might as well just go 3 bar.

                          http://www.racetronix.biz/itemdesc.a...S-001K&eq=&Tp=

                          Don't forget you'll need the connector for it as well. If you want 2 pumps you should really talk to Lonnies performance.

                          Oh and yes those injectors will work in the 96 rail no problem :)

                            thank you but what does the map sensor do exactly and why upgrade.

                            and thanks for the info on the injectors and pumps

                              MAP sensor reads the vacuum or boost in the manifold. Which means with a 3 bar map, your computer (With some additional tuning) will actually be able to see the boost and log it etc... it's a useful tool. And if you want an electronic boost gauge, or boost by gear etc.. it can make life a lot easier.
