If it's not too late, I would be down to put the 20%

[IntegraXTR]

Dinan has three different types of carbon fiber patterns (V1, V2 and V3).

It looks like V2 matches the Eventuri, but the V3 for sure does not.

If this was just a little cheaper, I'd likely be in for it.

But, given that it's a complete carbon fiber construction, I'm worried about long term warping from the heat of the engine.

It's also why I like the CarboProject the most, since they use the bottom half of OEM plenum, which for absolutely perfectly, and also no risk of warping/cracking from heat.

Looks cool af though, and looks like solid well made construction. Looking forward to seeing how they perform in the wild.

If that were to happen, I'd hope the 5-year structural warranty takes care of it.

Indeed, I'd hope that too. I wonder if warping/cracking from normal use is covered under the warranty.

I have it and paired with eventuri intake. Sounds great and right around 5krpm it has nice deep induction growl but tapers off as the revs past 5500rpm once you get to 7k to redline it screams. As for power I'm running stage 2 tune from Alpine Motorsports not sure if it address more power to be had from the plenum. Waiting to see which tuning company can squeeze more power from this unit. As for Alex from Alpine said he doubts there's more power to be had but he does have plenum map for just sound just list it under your mods list.

I share the concern about how this plenum will stand up to high temps. Is there anything from Haimus to address this concern?

Please refer to 7:22 of the video for Antony's explanation regarding the structure

While that is a very helpful explanation, that doesn't fully address the concerns about heat. The structure of a material while cool is far different than the structure of the same material while hot, especially considering how hot these engines get.

It is less concerning considering it has been designed for motorsport applications (as referenced in the video) however I would like more specifics as to how this will standup to high heat, especially considering there have been heat-related failures in other plenums (adhesives for example).

Agreed. Intense heat due to it sitting directly on top of an engine that redlines at 8400rpm. Also, the constant heat/cool cycles seems like they can weaken the structure and/or any adhesives.

Hopefully we can get a confirmation that at least the 5yr warranty covers this concern.

Also, is the warranty transferable?

I'll inquire with Haimus for an official reply, good questions!
