Message	"One of the ones I look at is, if you are running a fuel pump at max voltage the pump is pulling max current" Obviously you know WAY more than I do about all things electrical (which is why I mail my parts to you) but I am not sure if I agree. From my understanding when you are supplying 12V to the Walbro it isn't pulling max amps. The amp load will be at ~14. Then as the FPR raises pressure in relation to boost the pump will begin to draw more amps in relation to the increase. I have actually hooked up a data log to a fuel pump during WOT pulls to look at the amperage increase vs load. Here is how Walbro rates their pumps. Please let me know if I am missing something. Thanks! Madhatter10-6
Follow Ups	I called Walbro today..... - Madhatter10-6 15:19:52 05/07/14 Thanks, good to know - Turbodog (CT) 15:33:06 05/07/14 This is a good read on fuel control. - DVDBURN (MD) 16:25:48 05/07/14 ^^^ This. Pretty much what I was going to post. (n/m) - MixManMash 16:53:51 05/07/14 What current does the stock FP draw? - -Grimm- 16:56:23 05/07/14 The setups will not be identical. - DVDBURN (MD) 18:01:04 05/07/14 From the referenced article: - -Grimm- 09:42:27 05/08/14 The alternator will never be 100% efficient. - DVDBURN (MD) 16:13:35 05/08/14 Yeah, I used their 60% - -Grimm- 17:45:54 05/08/14 would an overdrive alternator pully help? (n/m) - LivinTheDream 22:30:48 05/08/14 It would help your output in the lower RPM - -Grimm- 12:03:37 05/09/14 The Z ecu will not get enuff voltage at idle with 2pumps - The Devils Z 22:50:55 05/07/14 Yeah? And? - DVDBURN (MD) 16:35:13 05/08/14 Re: This is a good read on fuel control. - Madhatter10-6 09:30:06 05/08/14 Ah OK. Thats good to know. (n/m) - DVDBURN (MD) 16:37:35 05/08/14 Technically, the FPC is not adjusting to various voltage - MixManMash 16:55:38 05/07/14 you just took his word for it without asking why? - aliaZ 18:50:28 05/07/14 I see another drawback : - Dark Diver 07:56:37 05/08/14 I may sound crazy but..... - Zvil (FL) 10:03:40 05/08/14 I used to feel the same thing when I used to top off - DVDBURN (MD) 16:44:41 05/08/14 Anyone ever installed a fuel cooler? - -Grimm- 17:47:06 05/08/14 I'm willing to give it a try..... if only there was a way to - Zvil (FL) 07:31:59 05/09/14 G force meter? - -Grimm- 12:04:56 05/09/14 so what you're saying is the amount of time - Zvil (FL) 15:47:34 05/09/14
