MORE POWER?
 

I have a 92 IC'ED 12v in my f250.. I just put in a BD fuel pin and 32k spring. I was wondering what i could do next or should do.... I also have an HX35 turbo with a welded shut waste gate...I previously removed the grid heaters as well because its my toy and if it doesnt start i have another one to drive. I know i can do EX valve springs, injectors (which injectors are best). What else is available for the rotarty pump? Ive heard of 14mm heads for the pump but wasnt sure on the cost of that. Not trying to make crazy power but the more the marrier :tu:

any input is appreciated!! thanks in advance!

Just a question,is your killer dowel pin dealt with?

X2 on the KDP
Gauges would be first if you don't have any.
VE pump upgraded are becoming harder to come by. Wouldn't advice a 14mm upgrade.

yep got ISSPRO EV2 pyro, boost, also have coolant temp but it isnt installed yet. AS for the KDP ive been very lazy with that little guy i need to get around to doing it so that will probably be the next thing i fix.

advise :argh: typo

If you want I have 6 60lbs valve springs setting in the garage collecting dust. I'll sell you for $60 shipped. PM me if your interested.

why not 14mm? just curious... and i will pm you

I'm no expert on the 14mm VE upgraded pump.. I have heard few people have good luck and a lot don't. I think JQmile is running one with great luck maybe he will chime in on this. But what I've heard is they seize up.. I'm guessing from not the right amount of lp pressure?

From what I've read the 14mm pumps need to be run at about 70 psi of fuel pressure. More if you're planning on running over 4 grand. At that pressure you need to put some extra sealing at the front of the pump. If you run less fuel pressure then you have seizing problems

I spent a pile of money and time on my 12V and am still modding daily, as a tech its kinda cool but at the same time I find I'm way too picky. As for power before my rebuild I installed the fuel pin from BD Diesel, also while I was at it did the spring to gain a few more hundred RPM's (this really helps lengthen the power band and these 12valves can handle 2700RPM all day long) I built my own air intake which was awesome for air volume availibilty and turbo whistle. I then dialed in my power screw 1/2 a turn located between the pump and the intake. Just doing some of this stuff really "smartened" mine up but of course I wanted more. I ordered the 16cm exhaust housing to help reduce turbo lag and noticed a big difference on the bottom end on take off. If you dial in the power screw you will notice an increase in RPM's you'll have to lower it a bit as you go. Don't dial it in too much (more than one full turn) and you'll notice a bit of barking at first until the increased pressure finds its happy place with the injectors. Man I could go on all night, anyways if ya got any questions don't hesitate to shoot me an email, I'll do my best to answer.
Once I started the rebuild that was a whole new ball game. Right now my 12V is at 300hp and over 600ftlbs of torque......still could make alot more but its all about how much a guy wants ta spend
Cheers

Did u turn the injector pump up and adjust the power screws?

If i have a hx35 turbo what injectors should be good with that?
