Edit- How about we table this until phunk chimes in. We're debating two sides of a post that may not exist Cosmo, I just **** up your thread every day.

I have sold more fuel rails for the VQ than any manufacturer, guaranteed. Several hundreds of sets. I have more user and tuner feedback than anyone on the matter.
No engine NEEDS dampers. But there are side effects to removing, and the VQ is very sensitive to it. You run into lean spots than cannot be tuned out. Many DE cars were suffering adverse side effects from removing them, and customers REQUESTED that we make a new rail with dampers. We did as requested, and even offered a several month long exchange program to swap out rails for customers experiencing the side effects. We gave out TONS of rails at hardly over our cost of time and material in exchange for the old rails back to mostly destroy to keep the used fuel rail market from flooding and halting our normal sales. There are long threads on the issue on the 350z forum, including a member showing datalogs going from no dampers, to 1, to 2, and eventually to 3. My personal 370z running the a prototype fuel system configuration where I removed just 1 of the 3 dampers already developed a lean hesitation at 3100rpm. Not all cars will experience it on a level that is noticeable to the driver. Datalogs will show it on any car with them removed. I have never found the ryhme or reason that determines which cars suffer and which dont. We had customers experience it with different regulators, different pumps, and all various injectors. We had so many customers that DID experience, that it was foolish to continue production of rails that do not have them, when we can just simply prevent the problem from occurring for everyone. The problem will easily be brushed off by many as a tuning quirk or side effect of a highly modified vehicle. But it is actually completely correctable. Personally, I dont care one way or another which system cosmo buys. SOMEONE is going to buy this used GTM system, which is one less sale of my system. So... makes no difference who buys it. I actually sort of hope cosmo does... cause he seems like the type that will speak his mind. Now that I am calling attention to the side effects he is going to see, he can simply see them for himself, and later on I will just sell him some rails that can swap right in and fix the problem. Its a win for all of us! ~2400rpm, ~3100rpm : Pay attention to how the car drives at part throttle light acceleration through these RPM ranges after you install the system.

Easy there dude. It was just a question. I still have never seen any parts you have designed for this community. So when you say a person who has contributed is motivated by selling product, you need to back up a statement like that.

A 3000hp car without dampers? The harmonics have no relation to the engine horsepower. They are also unnoticed during heavy acceleration because you pass through the "bad" RPMs very quickly. This a driveability issue, and totally unrelated to dyno graphs and horsepower. We have gone back and updated every fuel system we make to integrate dampers. We did NOT have to revisit our systems that I can hardly keep in stock. We did it for our customers to have a better final product. You're not correct at all... but lets pretend you were right about anything. Is there any reason to remove them? I mean... you already own them, they are on the engine already... if you can keep something that Nissan thinks your engine needs to run more smoothly, and it doesnt even cost you anything... why not? There are endless reports of the issue in the DE world. I personally saw the issue on my own VHR, and 2 weeks ago I was contacted by a popular Z tuner about a 370z with GTM rails, hesitating and bucking at the specified RPMs. I guess we will see how that gets fixed? What is the honest truth... do you NEED dampers on your VQ. No. Will your car run and drive smoother with them? YES, proven several times over now. How bad is it if you don't have any? It is anyone's best guess, as the severity ranges based on currently unknown determining factors. Some customers were completely fed up and annoyed by it, while many say they never noticed an issue. In the end, why leave the slack for it? Just do it right, and its done.

Let me point out the reason I started this thread was to get feedback from others who have (been there and done that) and know what works and what doesn't. That being said I appreciate the input of everyone willing to help but this cannot turn into something that could get it Locked. At this point after reading much debate I may just stick with my original plan and just keep the oem rails and drop my aeromotive 340 pump in. I have a lot of money so far vested in this project and I'm just trying to do thing right this time around... It's a good thing I have a very cool-@ss wife that loves the car as much as I do because if she wasn't I might have to apply at gtm for a job... lol

We tried to find an easy way to do that with our previous rails rather than having to make new ones. We found some aftermarket dampers that were large and clunky, had to run remote hoses to them. Overall it was messy. It forced us to have to create a masterpiece.

Just a follow up, I spoke with Charles at cjm and he comfirmed my stock fuel rails would be fine for my specific power goals and my aeromotive 340 fuel pump. To me that shows a lot because he did not push his fuel system at all and was honest about what he knows to be true with his years of experience..
