The "competitor's" intake managed to stay within 3 hp of it's hot and cold runs while the stock intake lost 7hp from the repeatable cold numbers to repeatable hot numbers, and the JF Cold Rush lost 9hp from the repeatable cold to hot runs...
Defining cold/hot: A new intake was put on cold. The car was started, and with the radiator fans hot wired on via the fan trick, the CLT was allowed to stabilize at it's lowest point with the hood open. Typically the CLT would get down to 199 before the runs were started with the exception of the last run which was the JF intake was started at 203 because it wasn't getting any colder, at the time the CLT was deemed at it's lowest point, the fans were turned off and the hood closed for the runs... For the "hot" runs, the hood was left closed after 3-5 "cold" runs (after a repeatable number was run), and the car idled for appx 5 minutes, when the "hot runs" were started the CLT was always about 216 +- 1-2 deg, then the car was run again until a repeatable "hot" number was run...
Unfortunately, I don't have the dyno sheets as the printer was not working as per my usual luck when I go to dyno something :( I'm currently waiting for the run files to be emailed to me, but im sure it won't be until Monday at the earliest now as I haven't received them yet. I do have all of the run numbers written down, just no curves.
Keep in mind, not only am I on a different dyno, but I've also added high flow cats, and a ported TB since my last time on the dyno, so the numbers won't really coincide with older numbers exactly since they are higher.
Stock intake runs
"Cold": 388 HP 395.3 TQ
"Hot": 381 HP 397.1 TQ
Brand X intake runs
"Cold": 392 HP 403.6 TQ
"Hot": 388 HP 399.8 TQ
JF Cold Rush Runs
"Cold": 409.0 HP 407.1 TQ
"Hot": 400.3 HP 413.4 TQ
Needless to say, it was interesting. I expected more of Brand X, but I find it hard to believe that the dyno, or the testing was being run improperly as I've tested my intake 3 times now, on 2 different dynos, with 3 different operators, and my outcome over stock has been about the same each time. This was the first and only time I have, or plan to run Brand X on the Dyno.
A note on these numbers, posted... Typically I will junk the high and low numbers, although in this instance the Cold Rush instance was a repeatable number so I kept it, the Brand X cold run "repeatable" number is less than shown, but I'm giving it the benefit of the doubt with it's highest run as I thought it would be more... "Hot" run numbers shows the highest run from two runs that were within 0.8hp of each other.
I will edit this once I have dyno charts to post.
