OK, so I did some research on the 14MM pump head, and failed to come up with what exactly this is. I under stand it as stock we are 12 MM, so obviously something is bigger. WHAT? and really whats the advantage? From what i have read this is good to make 400 HP somewhat easier. Im hunting for the 400RWHP mark.

And I see guys like KTA, and Piers are making them. Can I modify mine myself? I have pretty good mechanical skills, and if its nothing more then a drill, and tap procedure, im in! Im trying to locate a running or wasted VE for tear down, and R&D.

Thanks!

 

From what I understand from Wanna, the 14mm pump head is attached to the back of our pumps and can produce a bunch more fuel. I know there were some reliability issues with it when KTA first produced them, I don't know if they have been improved yet. I know for a fact Wanna can teach you all about them.

Sorry I couldn't be more help,

I would like a better understanding of this subject as well. Like where can I get one or better yet, has anyone made reliable horsepower with one?

 

Unfortunately, it's not something average joes like us can do. The VE has one plunger to feed all 6 injectors and that plunger rides (obviously) in one barrel. The tolerances of the plunger/barrel combination are so tight that Bosch only sells/makes them as a matched set--there is no mixing and matching. The reason the tolerances are so tight is because that plunger needs to produce the necessary pressure to pop the injector---6-8000psi, I think....Anyway, KTA had a batch custom made and I hear he just sold the last of them, with no more coming down the pike, according to what he told me on PM. I'm not aware of PDR fussing about with this, but I've been wrong before once or twice The lack of popularity is due to a poor track record of survival. Some guys made it to the bottom of their driveway before it took a dump while others have thousands of trouble-free miles on them. Those pumps at moderate HP levels (in the 400's) seem to last better, but I've herad there are exceptions to that rule as well. It's a real gamble for the daily driver set (me) but it doesn't look like there will be any more built anyway

 

92Diesel, You were typing the same time I was. You are just a lot quicker . Aren't you supposed to be at work?.........I am.

 

Boatnik, That was my lunch hou.... I mean 5min

Michael

 

Yep, mine too

 

Even thow it sounds like there will not be an eater Bach made the last scoop from KTA, on this board.......that i have read was that he had removed is 14 and had made his last run, on the Dyno with the 12 But was planning on putting it back on once he got a good base built with the 12................I sure hope that the last one he sold wasn't his own 14!

HAY "KTA COME AROUND AN FEED ARE CURIOSITY

Were starving.

Flash.

 

I dont know about supply of 14mm heads, but I think 400hp is feasable with the stock 12mm head and proper fuel supply, injectors, turbos, etc, etc. Stomp made 600+ on #2 only with a 14mm head.

The issue of reliabilty seems to be linked to fuel pressure and volume. They like a lot of fuel, as they have a 36% larger "surface area" to pump. (find the surface area of a 12 vs 14mm head, and you'll see what I mean).

Tolerances are extremely tight, because the pressures are more like 8-10K psi, at least at the settings that they run for 600HP.

what did a 14 come on stock?

 

I don't believe any thing.........thay were custom built!


Flash!

 

Dave? i figured you would throw you 2 sence..............silver dollar in!

any thing new. do you still have you 14?

flash.

EDIT

Just read "14mm VE roll call" glad to see ya still have it!

 

Nope, Greg took care of it and I had nothing to add. I do try to keep my mouth shut when I don't have anything useful to say.
