Re: Fuel Injectors
Got your PM cliff. The 205's will be fine for your app. If you are planing on a little juice, I would step up the injector size. Keep in mind, there are several stroker motors running the factory injectors.

Re: Fuel Injectors
I know what their site shows, but when you call them and ask for injectors for the LT5 you will get the 205cc.
I'm in the middle of a cammed 402 build. I would think it should have much larger injectors (600-650hp) A call to Marc, and he said no need. 205cc will work fine He tunes these more then anyone I know. |

I am assuming that the fuel rail (fuel pressure regulator/fuel pump) puts out about 50 psi and that fuel pressure does have an effect on nozzle sizing and fuel lbs/hour/injector I am also assuming that the fuel pressure regulator is not adjustable Last edited by Dynomite; 02-24-2010 at 08:04 AM. |

Re: Fuel Injectors
LINGENFELTER Performance Engineering does have an adjustable fuel pressure regulator for the LT5
http://cgi.ebay.com/ebaymotors/LT5-Z...Q5fAccessories Does this mean you can up the fuel pressure as you like with LINGENFELTER fuel pressure regulator resulting in more lbs fuel/hour/injector? Does this mean you can go from 205s to greater than 205 capability using 205s just by adjusting the fuel pressure? Last edited by Dynomite; 02-24-2010 at 08:09 AM. |

My 84 used a VAFPR that varied FP from 10psi at idle to 20psi at WOT. That gave a PW that was good for smooth idle and enough flow rate at WOT for a 75% DC and a 12:1 AFR. |
