high performance banjo bolts

[1965LONEWOLF]

got a set given to me for my 04. 5 600 cummins , is it worth the switch ? what will i gain by switching them out ? any feed back would be great

 

[1965LONEWOLF]

i can't believe no one has got back to me on this ? i know theres alot of smart guys on here, send me some thoughts please

Theoretically, you should see more flow, especially if you have an aftermarket fuel pump/system. But who knows??? Don't know if anyone's actually tested them. I have em'... . but couldn't tell the difference from before to after.

i do have a fass 150 pump and a tst box , i guess it wouldn t take long to do it , i was hoping someone out here did some testing and or homework ... . thanks though

Rob, I have the Geno's Bolts in my 24 Valve 2nd Gen, and they don'T seen to make much difference I still burnt up a bunch of Lift Pumps and one VP44... Moose

thanks , i wonder if its different for the 325/600 cummins ? i think i met you at mass diesel or atleast when he did a dyno day at mike dez 's place, i had the " pretty " red truck everyone said ...

Sir,

You must have a 3rd Gen in order to post on this forum



Thank you for your understanding,

I went banjo-less and gained 0hp... I am betting bigger banjos themselves will not add HP - but will help maybe keep PSI at the CP3 inlet?

Ditch the Banjo-Bolts where you can as they are restrictive to fuel flow. You are better off with a straight in fitting. Now why is this. Fuel volumn is the answer. The Banjo-Bolts were devised as a method to allow a nice compact method of attachment from different directions. This works well for an engine that would or could be placed into different engine bay configurations. The Banjo-Bolt was a universal style fitting. They work well for what they are, but they do restrict flow.



A straight in fitting allow a better flow for overall volumn of fuel which means that you get better pickup / supply performance flow for the VP. You might not see a HP gain but the VP will not starve either because it will have more volumn of fuel to work with.



It is a minor thing, but it pays off in the long run for reliability

Mr. MacDonald, I can answer your question from personal experience if signal73 doesn't get too pissy because I own a second generation. Some background info is first. My truck suffered a lift pump and vp44 failure at 60000mi. It still being under warranty, I was forced to accept the in tank lift pump conversion. I feel there is pros and cons to that system but time will tell. Anyway, I immediately installed a gauge set to monitor the pressures and I will pass on the results. As delivered from the dealer after the tank mods idle pressure 8#. Cruise at 60 mph 5#. Cruise at 60 mph with 8000# on behind 4#. WOT 0#. I didn't like the looks of this even if it is a high volume pump. Being as my truck is still under warranty I am somewhat restricted as to fuel system mods I can do (I did get written permission from my dealer for the gauge install). The high flow banjo bolts looked promising for the cost and they are not a visible warranty issue. The following results are after the high flow banjo bolts were installed. Idle 8#. Cruise at 60 mph 7#. Cruise with 8000# on 6#. WOT 2#. A marginal improvement offering some piece of mind. All these pressure measurements were made at the inlet of the vp44. Now from a design standpoint that is about the worst place to take an accurate pressure measurement due to turbulance and velocity effects (picture trying to take a pressure reading in a toilet bowl in mid flush). So I moved the gauge connection to the outlet of the filter which is about 12" away. All the test pressures remained the same with the exception of WOT now only dropped to 4# and this with 8000# on. In my case the improvement was worth it being confined by warranty issues. Keep in mind this information is pertinent to an intank pump conversion which uses two extra banjo bolts. Yes I know that there are a few ways to make greater improvements to the fuel system efficiency but none that will get past over zealous warranty enforcement.

Myself and the Moose go back a ways. Typical ball busting among friends.

I'll accept your lack of experience in that field as an apology
