Injector Size

[bomexe]

well i'm currently looking at a precison pt61 and a fully built motor the turbo is rated at 680 hp, but i dont think my numbers will go that high, my question is does anyone have suggestions on what size injectors to run, because i really have no idea about fuel stuff...thanks

Will need more info. What is your fuel management going to be?

I would get anything over 750cc, cause anything below it will max out at 450 hp. Plus you have to know how much power you are looking to make?

i plan on running hahn racecraft porfueler i want 500 hp and the management max out at 27psi and any reccommendations on injector brand....precision/accel/rc?

Honestly you better talk to hahn about what size injectors to run as secondaries with the porterfulers.

ONe setup I have seen recently are 235cc-275cc primary injectors w/ 450cc-550cc secondaries. As for brand names, I'd just look for one that won't malfunction.

Accel is the company of choice from Hahn.

The PF does not "Max out" at 27psi. it stops self tuning at anything above that. My fuel maps in the program go up to 65psi. You will need to have a serious tune to get anything above 27psi.

Are you sure? I thought the MAP sensor in their control unit wouldn't read anything above 27psi.

27 is enough for me not like car will be raced a lot i just want a good hp number so the overall consensous is talk to hahn and end up going with accel ?

The biggest injectors you can get from HRC are 550cc, without getting a custom order. They should be sufficent for up to about 400 whp.

I run stock primaries and 500cc secondaries. When i dynoed my car(369 whp) my duty cycle on my secondaries never went above 68%. That leaves a good bit more power to be had from my injectors. My secondaries are Accell brand but as others have said just get a decent brand any you should be fine. As far as the portfueler itself it stops at 26 lbs of boost(i just opened up my fuel map to be sure). And trust me on one thing that bi*** NEVER self tunes. It has no inputs to know how rich or lean its running. It does what you tell it and nothing else.

I thought so, but I wasn't 100% sure...
