Bottom Line on the 14mm head and 4mm cam plate

[mhuppertz]

I know this is sort of a duplicate thread, but I wanted to pull it all together if possible for some kind of bottom line.
So I go to you KTA (and anyone else who wants to jump in)...
1. How does your 14mm compare to the Rokentech head?
2. What is your take on the 4mm cam plate?
3. Assuming upgraded fuel supply to go along with the POD's (to keep the pump cool and lubricated), what is the projected lifespan of a pump with these upgrades?
4. I read about somebody putting high pressure seals in their pump so that the pressure can be raised. Have you done this?

I'm (at least) a year off from doing something with the fuel, need to get more air, but I really want to know the direction I need to head. I am commited to the rotary pump because of the mechanical advance (and I want to humiliate a P-Pumper some day!) I'm still somewhat faster than my nephews '97 with a #10 plate, but if he does anything else he will kick my tail-gate. That's just not acceptible!

So, what's my road map with the pump?

Im also ready to sink some more money into go fast parts.A Big 3 bottom turbo is in the works and I will be looking for ideas on how to do the supports and the hotpipe. but anywho...I might be aquiring a daily driver and that will be enough motivation to do the big things ive wanted to do. I want to try a 14mm h and r setup. some edms will be delivering the fuel. what supply pressure keeps the 14mm head and rotor pump happy?also if the 14mm heads are going to be difficult to buy in the future i would like to find one?any help is greatly appreciated.

I can't answer any of the 14mm or camplate questions because mine is not on yet but I can say that edm's and bigger turbos are needed for you guys first. POD's and hx-35 based turbos are nothing compared to some big edm's and s-300 based turbos. Hybrid over a 3b or s400 whould do ok but ya still have alot more fuel buried in the 12mm first.

this will be qiuck because i got to go but...

POD's not nearer big enough
rocken tech sent me an email saying that they dont recomend to use the 14mm and 4mm cam plate together, i will be
From what i hear KTA 14mm is better then rocken tech,

your going to need twins or a big single
your going to need 1/2inch fuel lines with an electric pump

the idea with the higher pressure is to keep the pump cooler by putting by flowing more fuel throught it,

when doing this stuff your making you truck into a play truck, not one i would be towing with or a daily that your counting on

You should read some more theads and do more homework, instead of juming into it, and always have another pump on the bench to swap out, i have 4 of them so..... you get the picture

1. How does your 14mm compare to the Rokentech head? It has a few internal diffrences and the metalurgy is a little diffrent.
2. What is your take on the 4mm cam plate? It should add more fuel, and a long with it more stress on the pump parts.
3. Assuming upgraded fuel supply to go along with the POD's (to keep the pump cool and lubricated), what is the projected lifespan of a pump with these upgrades? POD's are too small for that setup. I consider the 14mm as race parts. It all depends on your setup some have lasted years and thousands of miles others didn't make it out of the driveway.
4. I read about somebody putting high pressure seals in their pump so that the pressure can be raised. Have you done this? I have a stock seal with a retainer, it works fine for me.

hey brian, good to hear your truck is on the road again
