I have always gone by the rule of no more than 20 and no less than 10. I do think it makes a difference though. I made 507 HP on 5x5 but 493 on 0 on the box. I think I ran out of pressure and flow on top end that is the only time it has dropped beloow 10 and it went down to 8 psi.

 

This is the hottest topic goin in the 24V section, gotta be more opinions then this.

 

Well I aint no expert by any means but I will give my 2 cents worth

first off when yer saying we need 14 psi at the VP you are right and wrong at the same time ...........what I am saying is that pressure is simply a measurment of resistence to flow...the more the resistence the higher the pressure reading will be ...so if you have gone to a big line kit of any kind than you have alot less resistence in the total system and will hafta generate alot more flow in order to make or climb the pressure back up to 14 psi...what we really need at the VP and proven by our own DC dealers is flow...they do a flow test on a suspected LP when an owner is complaining right...well along with the propper flow or adequate fuel flow you will get a volumn of fuel that removes the heat generated from the VP and you also get the added lubricating properties from said flow...........what I am driving at here is that flow is what important not pressure....basically its easy to measure pressure and expensive to measure flow so thats why people usually are talking pressure...you are correct that there is an internal bypass at the VP at 15 psi so any more pressure than that is just a pumping waste IMHO

 

With all the flowmeters out there for ag usage it shouldn't be to hard to incorporate one into our use here, I wouldn't think. They use em on sparyers all the time and if they can handle chemical application they should be able to take diesel fuel.

Here's your chance, for any of you wanna be marketers out there to put together and market your own new product. Who knows, maybe you can be the next Gale Banks and you'll have me to thank.

 

That's what I was trying to say whitmore, I just didn't know it That's the ticket to this whole debacle. When I was thinking about it I knew I was forgetting something, the size of tubing to the vp. So basically, you need flow.

 

I would not thank you if I turned into the next Gale Banks.

That would mean I'd spend gobs of money on advertising for a marginally effective product.

I think a better example would be Marco from MADs Electronics............makers of the Smarty

Something like so, Dennis?

The Fill-Rite is fuel rated.

 

about 3oo clams will get ya into a flow meter........cant remember the name brand though

 

I found one here for $156 with AN/6 inlet and outlet that lloks like it would do the trick. This was just a quick search I know I can find em cheaper in farm supply areas.

www.floscan.com will get you a nice setup, made specifically for diesel or gasoline. I've got one laying in my closet that is intended for my boat.

As far as excess fuel being a waste; I think the more fuel the better flowing through the VP, anything to cool that puppy down as much as possible would do nothing but help.

 

I think if I were runnin a competition truck this would be a cool system to use. But way overkill for what I'm lookin for. They are sellin $1000 plus computers systems that monitor several things at once dealing with fuel consumption and flow. Unless I just missed the simple flowmeters on the site.
