Whatever "brand x" was... doesnt jive with the big JRE test I think... for scientific reasons, one may try to repeat the test on another car, and see if results can be duplicated.

I know he has someone else lined up that is going dyno this intake versus another brand. If I understood correctly this will be brand "T" tuned versus Cold Rush tuned. Now this will be a much more telling comparison since each will be optimized.

You are correct about that.
What has always been odd to me is that many will buy one intake, state it as the best, and never test it or anything else. Then there are others that find the need to actually look for better, even if it means making their own or in my case made a hybrid out of things I liked from 3 different systems. I really liked my hybrid but also found Vararam to be my favorite. With that said, I no longer have a horse in this race. However I stayed subscribed because Jason's motivation and hard work to make a better intake and bring it to the masses is interesting to me.

Why is this? Well, to my knowledge, no one else that has done this test can provide 60 mph winds at the front end of the car as JRE can... An intake comparison test w/ 60 mph winds vs a box fan on the front of the car will most likely show very different numbers. The big problem with some of the testing which has been mentioned time and time again by a few people is that while you're doing your daily driving sitting at a stop light, there are no 60 mph winds blowing on the front of your car while you're stopped and it's heating up... Hence it's a completely different test all together. The numbers will probably never jive, as Brand Y and Brand Z have shown... That is, IF Brand Y and Brand Z are stand up guys and would admit that they were producing an inferior product compared to Brand X.... Have I lost you yet? This was my first time running Brand X on the dyno, but not the first time on the street, or at the drag strip. I was honestly hoping for a larger gain to be shown here from Brand X, although when I've run it at the strip, I have typically seen very similar trap speeds to sock (usually within 1mph or less), so I should have figured as such would be shown. So back to the most recent test... The numbers the dyno operator wrote down on paper were all mixed up, some were standard correction numbers, some were SAE, and some HP numbers were even transposed from the TQ numbers... I finally received the dyno run files and was able to look at them myself and make sure everything was right. Please disregard the previous numbers, and for those just catching up, I have already gone back and erased the previously posted numbers. All numbers shown in the following dyno graph are SAE corrected. Runs #1 and #2 are the JF Cold Rush "Cold runs" then "Hot Runs", runs #3 and #4 are Brand X "Cold" then "Hot", and runs #5 and #6 are the stock airbox with stock filter "Cold" then "Hot"... 22 dyno pulls were made total, and these numbers shown were repeatable within 1hp or less both hot and cold. So getting back to 60 mph winds vs a Box fan at the front of the car... I've done this 3 times, 2 different dynos, 3 different operators, I'm seeing appx. the same gains when comparing the JF Cold Rush vs Stock, untuned, regardless of which design revision I have tried... With a box fan. This test was run on 92 Oct E10 fuel out of the pump. The JF Cold Rush box tested this time was tested with Reflectix insulation available at Lowe's as the new mold for the silicone insulation was not finished yet for the larger airbox, which may have something to do with the heat soak difference, however, it's the first time I've tested "cold" vs "hot", and as I've always said, you can't escape the heat. So the results may be the same even with silicone box insulation... When the intake tubes were removed, the Cold Rush silicone intake tube was just warm to the touch both inside and out, where was Brand X was burning hot as has been previously mentioned by several people in the past during daily driving. I guess the next step is to get the "production" Cold Rush intake to the Name That Intake! contest winner so it can be tested against Brand T(uned) vs Cold Rush tuned (if that's still a go)... Current time frame, is unknown but getting closer; the new box insulation mold for the larger air box is still being worked on, as is the "No-Tune" maf piece. The "Tune" maf piece mold has not even been started on and I'm still waiting for the prototype to be finished. Thoughts? |

Just using common sense here and just for conversation: I would just believe that if all variables except the intake are kept the same, it shouldn't matter. Yes you may get better numbers across the board with one "wind machine", but the differences between the intakes "should be the same"(numbers wise), using simple math.

Jason, I think you've made it as fair as possible. It all looks good and I wouldn't spend anymore time or money doing comparisons. However I do hope the comparison between tuned Cold Rush and tuned brand T happens.

Cool. I'll be waiting for it... probably a Christmas present for myself at this point
What is the theory on the tune version? Bigger maf housing? |

Pretty much correct. Because it will be tuned, you aren't limited by meeting the stock tune fueling requirements. With that said, tuning the no tune version should pick up a few more HP, which is what I'm so interested to see.

The MAF housing for the "tune" version of the intake will go on the outside of the silicone tube, which would allow for a true 4" ID intake tube with no "neck down" like the "no tune" maf piece... I think I am finally to the point where I am willing to tune my car, so I will probably test out the first prototype on my car when it is ready... I just have to figure out who and/or how I will tune it. There is no one local.
