Hey anyone looking for a reliable rotor head for $300 rocken tech is where to look. I just got my pump back in a few weeks ago and I could'nt be any happier the old girls fueling like a p-pump now

 

Be carefull putting the two words 14mm pump and reliable in the same sentence.

They make a huge difference in the way the truck drives. I love the throttle responce and the extra fuel on the high rpm side!

 

Your running pods and a hyrbrid H1c? dang your egt's must be high. i thought 14mm pumps liked bigger injectors and MASSIVE amounts of fuel running to it.

Whats your fuel lift pump setup?

 

Making it 3 weeks does not equal reliable in my book. Get 10k miles on it before you call it reliable.

 

what makes it so unreliable?

 

Im running an edelbroch 160 gph pump with half inch lines from the tank. Well I havent melted a piston yet as far as reliable goes as long as The pump gets a good volume of fuel supplied to it I dont see why it wouldnt be. And it was way better prced than KTA's rotor head.

 

The added stress of the larger plunger is rough on the drive coupler and the cam plate and rollers.

 

I wouldnt worry about the pistons, they are the least of your worries. It all deppends on where the pump is set. If its pushing the ragged edge and your running POD's, its not gonna last long. But if its mildly tweaked (medium fuel screw setting) it will probly be OK, if your lucky. Some guys have good luck with em and others dont. Ive destroyed one and im fixing to try and destroy another.

 

well for the road I have it turned back besides you cant even shut the truck off when the pumps cranked up so thats deffinitly just for the strip. I'm not too worried about the pump I knew what I was getting into when I purchased it, Ive done plenty of research and know the pros and cons.

 

JAyers why do you think you destroyed the first one?

 

I'd bet it was the 4mm camplate ......

 

The main reason is that I was just pushing it too dang hard, fuel screw maxed....which caused the engine to overspeed....then the h&r seized at 4700rpm. Granted I was also running the 4mm camplate and that im sure didnt help anything. But it wasnt the cause.

 

JAyers did you get the 501 hp when you had this setup on there? Did you run the 14mm H/R prior to adding the 4mm camplate or was it all installed at once? This sounds like a heck of a setup but as you said 14mm and reliable are not good in the same sentence. I have a 14mm H/R but been kinda waiting till I had a spare pump, now I have 2 spares so I guess I'll try it. Any good advice, pitfalls, ect. you have will be appreciated. Good luck with your next try.

 

I had the 14mm H/R and the 4mm cam plate in when she rolled 501hp. I needed more air at the time. Just make sure you have a nice fuel supply and at least 6x.016 injectors, these are the two main supporting mods for the 14mm H/R, IMO. Enjoy the throttle responce and the new found fuel! If you need anything else feel free to PM me.

 

well I just sent my core injectors in for a set of 6x.016 EDM's so I'm just playing the waiting game now very anxiously:]
