I've netted 330rwhp at only 11psi and vosko has seen that.



All I had was

S5 stock engine,

to4 turbo

greddy fm IC

Haltech e6k at the time

720/1600 injectors





A friend that had my old hybrid netted 308 rwhp with similar mods.

hmmm iceblue, well im not gonna argue... I agree.



what would be an ideal fuel system upgrade running 10 psi? My goal is somewhere close to 300hp too, but not too soon here. However, i wouldnt want to blow my motor anytime soon either :P Sorry for the jack cryptic.

I agree. It might be running rich at idle and low load/low rpm conditions, but when you're at WOT, it's bound to be going lean.

I would get a Walbro instead of an FD pump. Is probably cheaper and can outflow more at higher PSI.

larger secondary injectors (680 or 720) and an fd or walbro fuel pump. plenty of fuel

Thanks guys!

FC RotorHead You can do it on flow tested stock injectors with a FPR and walboro or FD pump. If you are going to do the fuel mods no need to cut it short. As j9fd3s said some larger injectors will do it.

well... i dont have a standalone to manage all that fuel system..... so im stuck here for now... I posted a separate thread so i didnt jack crypts.. please look at this.

any input is appreaciated!

where can i find 720cc injectors can only get them if made custom and does any one have an opinion of the 750 injectors also will they be compatible with the rtek 2.0 website says its preprogramed for 720s. will it still work with the 750s? also is the rtek2.0 a good management computer? or are there better out there for around the same cost? i am also probly looking to be pushin more hp then 300 with the expense of a hybrid turbo and large ports.

why is there no edit button? any way for those who think im a retard for talking about an s5 and rtek im srry i own an s4 and just kinda jumped in to this topic because im looking for similar results with a similar setup



why now is there an edit button?
