Ive been doing my build 1 piece at a time and its coming along well enoigh for my liking this far. Im looking into a set of injectors now, but I cant find any comparisons online to any of the current groups doing them. Ive purchased many of my parts and upgrades from THD and am co sodering their injectors, but i am also curious about the PDD Power Jet line. Has anyone seen sode by side comparisons?

My goal long term is onl ly 500 horse with no smoke that i can reliable tow/ haul with at 70+mph. And still be able to comfortably drive around town when i feel like it. Also fuel economy. Im getting my ve pump co pletely rebuilt and resealed tomorrow duento the recent one at a time 400kmile seals going bad, and while im at it im putting a THD KSB timing spacer in. Prior to the leaking seals, with just thd fuel pin and 366 spring i was able to tune the pump up to 22mpg around town. Any suggestions or useful links for research are appreciated.

 

500HP, towing and hauling at 70 and fuel economy...That is a tall order to nail all three.

What are your plans for the turbo? Even if you just wanted 500HP and towing at 70 comfortable WITHOUT getting good MPG, you are going to need more air. Otherwise things are going to get hot, real hot.

 

I havent got that far yet. 500 is a long term goal. Short term is 300 to 350. 500 i noght have to go ppump better head and different i jectors all together.

So for now im just looking for info other than individual marketing numbers.

 

Injector companies make it hard to compare them. One guy lists their injectors by hole size and count, the next calls them 30+ or 50+ HP injectors.

Few people do back to back tests on different injectors as it would be a costly experiment. So you are left with all the makers of these injectors telling you their injectors are the best and make the cleanest power. Which we know is not possible. If there are 10 companies out there, they are not ALL the best.

 

You won't hit 500 with a stock IP rebuild. If you haven't sent it off. I wouldn't. I have sources on IP tech.I have done lots of research on the injectors. I PDD and DDP have a quiet collaboration going on on the "power jet" injectors. I have to run to Nashville and can get you some hints. I will drop some videos on IP mods.

Do you have an A518/46RH?

 

I am a member of a 1st Gen FB group. It's basically Eric from THD's place although he doesn't participate much, His wife came on there not to long ago as they weren't shipping product out due to his health. He got bit by an insect (brown recluse?) I don't remember. Some of the products not getting shipped was injectors. I think they are either back to normal or heading that way.

I sent my IP to him to get modified to his designation of "Max Fuel." The specs are on DAP's website. I'm not sure how much HP it can support. I will be happy with 400-450.

"VE Injection pump from The Hungry Diesel.Options are stock built ve pump. (90cc of fuel)
Maxed out stock ve pump. (250-260cc on average). Including THD fuel pin and gov spring of your choice!" They are not selling the THD pumps at this time for whatever the reason.

That's the pump I ordered directly from THD. Promised 4-6 weeks. It took 5-5 1/2 months. Lots of excuses. He did not get the bug bite at that time. He did take a trip to Firepunk diesel for the VE44 shoot out where he came in second in HP.. IIRC he was over 700HP without NOS. However AFAIK he got sick after mine shipped.

When the time comes I will not send my spare IP to him to get modded. Ratman is probably where I will go.

From what I have gathered from Eric, and other people who run full on VE race pumps (more potential than mine) they have good street manners and are good to go for towing.

PDD Powejets. I pinned down a guy who said he worked for PDD. He admitted they were in cooperation with DDP. DDP may have a patent on the nozzle design. They are more expensive to buy at PDD. At DDP you have the option of different degrees of power. You can buy the nozzles separate from DDP and rebuild your own. I did that. I have not ran mine yet. Last summer DDP ran a special for $400 parts and return shipping on your Bosch cores. Keep an eye out for that again. I took advantage of that so I have 2 sets. Both of mine are Stage III's. DDP has rated them 400-450hp depending which way the wind blows.

If you have a A518/46RH a stock torque converter will slip too much it will eat the trans. In the last couple of weeks I have come across 518's that can handle up to 700hp off the shelf. I am not wanting to go to the 47RH swap route. I have a spare to use as a core or rebuild. I really don't want to put the downtime into doing the swap and finding a dependable local shop to shorten the drive shaft.

I have a turbo that allegedly will do 450.

Here is a link to some HP VE parts https://www.rocken-tech.com/RotorHeads.html in case you want to try and build your own.

Here is a video for swapping to high volume delivery valves.

 

still running the getrag with ibtentions to go g56.

 

Maybe it's just me. I think he P pump is much more complicated than the VE. 500 is an easily obtainable goal nowadays with the VE. In this video they allege economy is better with the VE.

Your mileage may vary.

I had my chance to get everything to convert pretty cheap. I hesitated and it got sold. I think I like the VE more.

 

The injector hole size and count is a more 'faithful' spec to me.

The +HP thing is convoluted because the VE trucks had different injectors IC vs non-IC. The non-IC is probably already a "+50hp" injector, so what is the advertising actually comparing with?
