H&S Motorsports Dual High Pressure Fuel Kit with CP3 11-16 6.6L DuramaxThe potential of the LML Duramax to deliver unreal power has been proven. Simple programming and exhaust modifications have pushed these engines well past the 500 RWHP mark with ease.

The potential of the LML Duramax to deliver unreal power has been proven. Simple programming and exhaust modifications have pushed these engines well past the 500 RWHP mark with ease. And as diesel enthusiasts typically do, the limits are being pushed to see what kind of power can be pulled from these trucks. One of the limitations found is the factory CP4 injection pump. While this has shown (so far) to be a reliable pump, it's also shown to be essentially a bottleneck. When trucks are pushed above the 500 horsepower mark, the additional power gains begin to diminish due largely in part to the lack of rail pressure. Because of this, HS Motorsports has developed a dual pump system to cure this issue, and deliver enough fueling to support 900+ horsepower!

Just as a quick reference for you diesel nuts out there, the engineers at HS Performance were able to run 3800us (not recommended) of main injection duration on stock injectors without a drop in rail pressure. So what does that mean? Well, think about it this way; their off-the-shelf HOT tune commands around 1400us and is on the verge of draining the rail on a stock CP4-equipped truck. At 3800us, that is a 270% increase in fuel demand from their HOT tune and limit of the stock CP4. The HS Motorsports Dual High Pressure Fuel Kit was able to maintain the commanded 29,000 PSI rail pressure without skipping a beat.

One of the HUGE benefits to this system is that it includes a BRAND NEW CP3 from Bosch. That's right, BRAND NEW, not a remanufactured unit like many other companies utilize. The key to ensuring the longevity of any high pressure fuel pump is by providing the high pressure fuel system with clean, waterless diesel fuel. Any fuel contamination that reaches the high pressure fuel system can be detrimental to reliability and performance. Because of this, we highly recommend using a FASS, AirDog or similar lift pump for proper filtration and water-separation.

Why does HS use a CP3 in instead of a CP4?

There are a few reasons they chose the CP3 over the CP4:
  • The CP3 pump has been proven to be reliable. This pump technology has been used on the Cummins and Duramax platform for years.
  • While the CP4 has the capability of delivering higher pressures, it lacks the volume of the CP3. With both pumps installed, you get the best of both worlds - high pressure and high volume.
  • Price. With the CP4 being a newer pump, it is obviously more expensive. By saving on the pumps included with the kit, we can pass that savings directly on to the customer.
  • If your fueling demands exceed what the stock CP3 and CP4 are capable of providing, one of HS' 6.7L Cummins 10MM Stroker pumps can easily be used as a replacement while still being able to re-use all fittings and lines included with the kit.
IMPORTANT NOTES:
  • This product will NOT work with trucks that have dual alternators. The HS Motorsports CP3 pump is mounted where a dual alternator would be located.
  • This product may not work with the EGR cooler installed. It may need to be removed.
  • This product MUST be used in conjunction with custom tuning calibration. Failure to install the correct calibrations can result in engine damage.

Omegaverse
Format: Kindle
I was pleasantly surprised by this omega verse book. This 1 definitely had a few new twists And I really enjoyed reading it. The main female character was a badass and awesome. She had 1 best friend I wish we could have seen a little bit more of their friendship in this book. Her relationship with the male characters was good not to contrived or super instantaneous. And we had some fun plot twists that I didn't expect. I wish we had more of a follow up on the situation with her family her background and her mother who was a wench. I would definitely recommend this book.

Wow. Just wow. An amazing read
Format: Kindle
This book was eloquently written, or should I say the authors writing style is very eloquent? I loved the characters, and the story was quite compelling. I absolutely loved the FMC, she's a BA who doesn't take any crap & gives as good as she gets. A certain person certainly got his just desserts & then some, the earlier scenes of which were quite satisfying, had me punching the air & everything haha. All in all 20/10, great read

My opinion
Format: Kindle
Let me preface this by saying I really liked the story and the characters however, this book is in desperate need of some sort of editing. It's not misspelled words or formatting, but continuous run on sentences. Redundancies within the sentences. There were a couple of paragraphs that I had to go back and reread 3 or 4 times. Overall, I'd say it was worth the read.

Beautiful
Format: Kindle
I love omegaverses I had looked at this one multiple times thinking it's just another book about cocky rock star guys that let fame get to their heads and there are parts like that so I wasn't 100% off. I started reading the second book and met the fmc Astraea from the first one,after she had a run in with the aphla from the gym.😁 it gave me the push to stop and read book one first and im so glad I did this book was amazing their was so many characters I fell in love with hoping they will find their happily ever after. the guys were great, the plot was 🎯, and the ending had me 😭😭😭. I was wondering how nate could ever redeem himself, and he did. the last scene with him was sad, but I also felt it was beautiful. thank you to the author for making a beautiful omegaverse book that gave me all the feels. now I'm jumping straight into book two.

It took me a day to really get into the book, there is a lot happening in the beginning of the story. I wish there was more of a time frame because I felt like something’s happened quickly but they were farther away than I thought so that was a little confusing to me. I felt like there was so much happening but also not enough. As for the story itself I enjoyed it, it was different than other OV I’ve read. Bring the tissues, you will need them. They guys were great, I wish we saw more of Kai and Kenjis relationship. As for Nate…… IYKYK. I enjoyed this book, my first from this author and look forward to reading about Kamaris story. Book: ⭐️⭐️⭐️⭐️/5 Spice: 🌶️.5/5
