Hi,
As it is explained in the video details on the right side at youtube this was a tuning shakedown run. The car wasn't on its final tune it was just a trial video to show how the car sounded with the HKS single and with a turbo to the people in the HKS single exhaust thread.

The day after the video was shot we found a 1" diameter hole on one of the silicone couplers to the intercooler which was leaking a massive amount of boost causing the turbo to spool slowly. The hole was a puncture one that was probably caused during one of the many trial installations and grew as the car was run under boost to the point where it was huge. I can assure you that after replacing the coupler its a whole nother car and a new video is in the works and will be released shortly with an improved tune on the maps and no holes of course()

Fantastic, I was wondering why I didn't hear a BOV

 

Nice

 

Glad to hear the issue was a simple fix.

 

We felt like this before we found the leak:



Then we figured it out and felt like this:



Then this:



Now like this:



And the car is so fast when I am passenger I sometimes feel like this:

 

Looking forward to seeing more on this.

 

Broken coupler will definitely ruin the experience.
It will spool just fine, with no resistance on the compressor, and over-spin too trying to make the desired level of boost, that just keeps on escaping.
I can't see the video (my company blocks youtube), but looking at some of the pictures I have noticed that you have blue single layer silicone/rubber couples in your install. From my experience those things are really crappy. They pop like balloons at around 10-12 PSI. It would really benefit you if you got some reinforced couplers with T-clamps. I never had to worry about it popping or slipping ever since they were put on my pipes.
Unless off course those are old pics, and you already took care of it.

 

We actually beaded all of the intercooler pipes except for one so Tbolt clamps won't be needed until 25 psi or so but it can't hurt. The one that was not beaded was the one that popped off in a later run. As for the hoses we know it can go to 20 psi, don't ask and they have about 9000 miles on them at various PSIs. The hole was caused by a small tear when during the most recent reinstallation the screwdriver slipped into the side of that exact coupling. I did not inspect it thoroughly enough.

We'll have more details for you guys soon...we have kept mostly silent so Christian and the other engineers who assisted could focus on the kit instead of speculation, I hope everyone understands.

 

understood I'm looking fwd to this kit.

 

Dam I like the sound of this!

 

The kit has been released on the esmeril racing turbo kit thread. www.esmerilracing.com or www.mazdaparts.com This is the old thread.
