 In my down time lately I've been reading alot about injectors for the VP44 24 valve. Trying to learn and read reviews check prices and the like.

 I have looked through DAP and some others. Some look kind of "shady" or maybe that isn't the term but for whatever reason I didn't trust what they were saying. One on the other hand one seems to make some sense, Dynamite Diesel. All I know about this company is what I saw and read on their site and reviews of their products. I was just wondering if anyone has used their injectors? I did notice however that their prices are nearly double compared to DAP so I'm also curious as to whether or not it's worth it.

 .I'm not trying to start anything here between companies by any means nor bash either company. Just wondering how or why the price of the injectors can vary so much.

I'll be in the market for injectors come this summer so thought I'd start doing some homework and came across this issue so thought I'd put it up here and ask others opinions.

 I'll most likely purchase from DAP when the time comes but my curiosity got me on this.

Good way to break a stud. high chances of hot torque will make the studs fail... Again straight from ARP - DO NOT do a hot torque. Why would you want everything expanded and try to clamp the head tigh

Makes it easier to get it all over your clothing 

At least you 2 must no how to delete. I have never been successful. My diarrhea of the mouth is permanently on the record.

Dap or dfi if you want a budget injector,. Infinite performance if you want the best.

 

Dynomite diesel should be avoided.  They are the bro dude choice due to youtube and magazine pushes.

What so special about their injectors do you know by a chance. Do they use some fancy nozzles and springs that don't lose pop pressure as fast or are they just aimed towards performance more somehow, spray angle etc. I mean 150 hp injector is 150 hp

I believe it comes down to the quality of nozzles etc.   Kinda like a bosch alternator vs in house brand.  

 

 

Each has their place and i am not knocking either.

I looked on their website for my injectors and they are pricey for sure. There must be some word out there among mechanics on why they are the best, because it says nothing about why theirs are better.

Me78569 couldn't have said it better.

Weston's injectors are the best. Hands down. I have been running his 6x13 for 5 years. I recently sent them in as my truck was down because a rocker arm bolt pulled out of the head. He went through them & made a couple of adjustments & then returned them with all o-rings & coppers for for free. Now that's what I call quality control of something you build & stand behind. They were extremely powerful before he gave them some love, but whatever he did has made a big difference all around. I ran a short 35 mile test to see what kind of mileage per gallon & was floored. 23.8 mpg. This was on flat ground & straight with no hills. Call BS, but you will never know if you don't run them. Infinite Performance says it all in his name. The Quad is dialed in right, that is for sure. Unfortunately my truck is down again. Just ate the 3rd ECM. Working on number four. That's a whole different story.

 I was just kind of curious why different companies have such a variance in price. Thought some of it could be due to different processes involved.

 When it's time I will most likely use DAP since I see many here have used them and been satisfied with their purchase. Also I believe they're a vendor and/or sponsor here as well and price point to add to the list.

 If I were going full on performance high horse power twin turbo coal rolling tire shredding diesel dominator then maybe there would be a reason for dropping big $$ on injectors but mine is a daily driver, wood hauling, camper pulling and farm truck. I don't need or want all that stuff.

Some people are more proud of their injectors than others.

Both my VP44 pump and RV275 injectors are from DAP

I’ve had two sets of injectors from DAP now and been happy with both. The first set I purchased from them will be rebuilt to match the new set so I have spares should I ever need one. The sales person I spoke with on the phone when I ordered the second set was very knowledgeable, listened to my concerns with the truck without talking over me or trying to up sell things I didn’t need. I will definitely use them again.

Good to hear you like your injectors. I put arp bolts in my rokers when I did some other work on the head. They are longer and will prevent pulling out of head, for whatever reason they machined it almost another 1/4" deeper and used shorter bolts.

I had some issues with them in the past close to 8-10 years ago, I believe they changed some staff and their modo on how they do business now, last few sets I got I'm pretty happy with along with few other things I got from them. I just wish they wouldn't lose pop pressure so quickly, that's why some of us request higher pop pressure when ordering.

The prices of his injectors are well in line for what you get. Now CR injectors are pricey. I see nothing wrong with DAP injectors for everyday use. But if your looking for what I have built my engine around, then Infinite is the way to go.

I did upgrade to the ARP STUDS (247-7201) instead of bolts. More clamping force. Stock is 27 lbs. & these are 38 lbs. torqued. Not going to pull these out.

Not sure why they call it studs, it's clearly a bolt :think:

 

Because a bolts have a hexagon head on one end and threads on the other, and studs are typically threaded on both ended hence its name.

Most Goggle pictures of that part number, the studs certainly look like bolts. I found one photo I could zoom in and see they must be studs. They REALLY look like bolts!

They are bolts, how I know is I used them. That's why I'm not sure why they call them studs.
