Message	I've always found good info from Toyota that closely relates to our cars. [ http://www.autoshop101.com/forms/h42.pdf ] There are actually good reasons to use fuel pump speed control. One of the ones I look at is, if you are running a fuel pump at max voltage the pump is pulling max current. Doing so robs your car of power at low RPMs where it's needed if you race. If you run fuel pumps wide open it's a must to upgrade to a high amp alternator. Otherwise you'll most likely experience stumble, noticeable or not, when you punch it from a take off. Any time your system draws a lot of current the ignition system suffers. www.mytwinturbo.com Nissan Data Voice - The first Nissan diagnostic software with a voice!

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
