I do take a suppliers "findings" with a grain of salt though. The ACE header, with it's EL design should see better performance over any UEL header in an NA application, because physics, as for boosted with the help of blow through, I'm not sure. Boosted?, I haven't tested that, my AVO runs its UEL. But talking NA, and supercharged, how much better than the decated OEM is the ACE though, and which ACE, as there are a few different choices. Whilst the design of the ACE header is spot on, that's alot of money when we don't know the difference it gets to a decated OEM EL header designed by Subaru. I acknowledge the compromise made to the length of the OEM secondaries due to requirement of the OEM cat. https://www.counterspacegarage.com/a...0-brz-frs-gt86 $1700USD ( on sale) = $2500AUD = Alot of cash for unkown gain. What's the difference when you compare red apples to green apples, the ACE vs the EL JDL 4:2:1 with a $100 overpipe (a 2.5" pipe is a 2.5" pipe) > https://www.counterspacegarage.com/jdl-421el-ft86 Cheers.

Likewise, because the engine is the limiting factor, most catless headers all make the same peak power NA, but when you compare AUC, the headers start really stratifying into different tiers, and when you add boost, the superior designs become really, REALLY obvious. |

But, I'm just a consumer playing around with a limited budget. I'm not trying to sell something with power claims. I would actually advise against an UEL header, but then again, I'm just a consumer not trying to sell something. Manufacturers and suppliers are making claims in order to sell stuff. I like when manufacturers and suppliers can back said claims with unbias, independent data. Meh

You're implying that suppliers are all inherently biased. Strangely enough, CSG sells the UEL header tested, as well as the Ace header. So, where's the bias? The UEL header has a larger margin. You, the consumer, are unbiased. That, is why I think you should supply the data! |

And of course you sell the UEL header, your a supplier, there is a market, it would be financial suicide to not sell them. You have said that your findings have found that a 4:2:1 ACE header is better than a UEL header, I agree 100%, any well designed EL header would, it's 101 header design, people should buy the ACE over any UEL header. But The question was how much better is the ACE over the JDL 4:2:1, why spend $500 extra? Hell, how much better is the ACE and the JDL over a decated OEM header? I'm not selling anything, I'm asking a supplier who is making a claim, I'm just asking questions that any consumer that wants to know what he gets for his money would ask. It's up to the manufacturers and suppliers to prove what they say, not the consumer. I'm not saying testing is easy or cheap, the ability to test one part against another, using the same base never is, but asking a consumer to do the testing? Yeah nah. Anyways, it appears you have already done all the required testing anyway. "CounterSpace Garage sells only the highest quality products torture tested under the harshest conditions available. Every product offered by CounterSpace Garage is tried, tested, and proven." I'm pretty sure we are not on the same page so have fun at the track and good luck with your business.

Cylinder temperature and pressure over time break rods. It's not about psi or some vague concept of boost. Running a supercharger at a higher speed will leach more power, but it's not going to put massive strain on the engine, nothing like the strain of more cylinder pressure or temperature. More efficiency is a good thing, of course, and for the same WHP would likely mean lower temp, pressure, and fuel use. If you're running a stock engine, making a lot of power down low is a bad, bad idea. Where the stock breaking point is will vary by engine and tune.

- equation is PV=nRT. And "Yes" increasing P (means pressure) increases n which is number of moles of gas (means amount of oxygen, 21% of air) for given T and V. BTW, R is gas constant - but I never mentioned about oxygen above anyway |
