I am running stock TPI MAF, SDPC Vortec intake, Vortech Heads, LT4 Hotcam, 1.6 RR's, SLP 1 3/4" headers, forged pistons, 255lph intank fuel pump. Will 24 # SVO injectors be large enough for this combo? Also, I will have PCMforless burning my chip. What injector constant should I tell them to set? I have heard that SVO's will flow more because of a difference in GM and Ford's fuel pressure. Any help will be greatly appreciated!

Thanks,

Absolutely, YES. Have the chip burned for 24#/hr injectors. This should ??? force the BLM values to be near 128 or under 128, which I think is what you want.

Also, install an AFPR. By adjusting the fuel pressure, you will be able to dial in the right fuel at WOT. At 58psi fuel pressure, these injectors will flow about 28#/hr and be good for up to 380HP at 85% duty cycle.

The difference in flow rate between these injectors and LT1 injectors is very small, based on 39psi rating VS. 43psi rating. In fact, do a search on flow rate. I believe someone on this board flow check 24#/hr SVO injectors and they came out at 24, not a little higher as was expected, which was 25.2#/hr.

 

Thanks Doc. I am glad that they will work because I just found a guy at corral.net that is going to sell me a set brand new for 125 shipped. That's a whole lot better than new from summit. Once again thanks for the help.
Thanks,
