If I remember correctly, they use a company out of North Carolina on the 55 airboxes. Excellent quality, NASCAR shop. Primo stuff (and priced accordingly).

He's fine. It's just a reactionary thing - like, being 100% honest, whenever I hear RENNtech I go "Ugh!". In this case (the 55K airbox) I believe they (RT) have a superior quality product, but I still feel that "Ugh!" feeling. I'm guessing MB feels that a $2k product shouldn't yellow over time - regardless of how much time we're talking about.

That said, I don't care if it turns green or yellow or pink over time, the Carbonio product delivers real gains, doesn't de-laminate, installs easy, and undercuts the competitors by (usually) several hundred dollars.

I do not have any direct relationship with Carbonio (never bought parts from them), but because I organize many local events such as dyno days, drag events, road courses, etc.... I have seen many different cars with many different mods. And every single car I've seen with Carbonio parts have had those parts yellow out. You can ask the owners themselves if you like.... many of them are well-respected members on this board. Maybe I will take pictures next time.

I have a few responses to this post:

1) I have seen a couple of Carbonio products delaminate in the corners. Granted they were only a couple of cases among many, but they still do exist.

2) The Carbonio airboxes for the 63 make no power what so ever. If you would like to see more data on this, please search the C63 section of the forum. They have tested those boxes independently on different cars on different tracks/dynos.

3) The "yellowing" issue is not a "reactionary" response. I've seen it with my own eyes on many different cars and have experienced with their engine cover. In fact, I have yet to see one carbonio product that has not yellowed.

4) I had a $500 carbon fiber front lip for my C32 from EuroTeck and the lip has not yellowed (or even shown signs of wear) in the 4 years I owned it - and it has seen more abuse than any airbox will.

5) I actually like the Carbonio products except for the "yellowing" issue. I hope they tackle that part on future products.

No offense intended, MB. "Reactionary" isn't always a negative term.

Hey Mo, did Carbonio do Victors first run of VRP boxes...or first few runs I mean. Just curious as I have one of Victors boxes and no yellowing yet. I DID just buy the Carbonio fangs so I am nervous now.

How long before I see yellowing?

On a side note, if the Carbonios for the 55 are the direct son of Victors original design, I am a huge fan of their power increases.

I gotta find the dyno but it jumped quite a bit when we popped on the VRP box compared to stock. Lemme see if I can find it. Been years now.

I have had the Carbonio pythons, air box and engine cover on my car for over a year zero discoloration.

James@ACG

Jim yes the VRP 55k (victors) are the same as the carbonio 55k airbox.

James@ACG

oh and lastly we have 3 in stock

James, I guess I could ask you since you stumbled on this thread...

Have you seen or found a solution for the yellowing of this box? I bought a used on about a year ago from a buddy here in Denver and this thing has turned south quick TIA

In terms of power gains, Carbonio's 55k air boxes do produce power, but their 63 air boxes produce absolutely 0 hp gains; we've tested them on the dyno and on the track. In comparison, the RENNtech airboxes for the 63 produced 11 whp on the dyno and about 2 mph increase on the track.

Regarding the yellowing issue, you maybe able to see it better if you put it against another high-end carbon fiber piece. At the last Famoso event when the cars were cooling down, some 55k cars had both the RENNtech airbox and the Carbonio tubes. The tubes looked like yellow dirt next to the RENNtech airbox. Next time I will try to take high resolution pictures to illustrate the yellowing. It is most noticeable under the sun.

I didn't take it as negative at all.... I just wanted to point out that my judgement of the product comes from hard physical evidence. It is based on data from numerous cars over the past few years. I've been exposed to many 55k cars with the Carbonio boxes and/or tubes, and to date, I have not seen one that has not turned yellow. I'm sure some of them yellow slower than others, but in my estimation (due to the adhesive they're using), their products will eventually turn yellow.

You should take a few pictures of it under good sunlight and post it here so people can see the difference. I will try to take more pictures at the next track event and post it here as well.

James@ACG

the issue at hand is the resin that is used and the heat that the motor creates... the same resin used on an external body part would most likely last, however with the heat conditions it faces under the hood the resin starts to yellow... we're trying a few different solutions such as re-clearcoating to see if it helps, but unfortunately with a wet resin it may not be possible to avoid. but we are trying and will let you know

So how much power will the full setup make on a stage 5+ car?

Helped make 530whp 599wtq on a mustange dyno( mods in Signiture). Helps top end substantially. Don't have before and after dyno so can't give you specific numbers.

correct, when they established the product it was on the basis that Vics first runs were his to make his money, and carbonio could use the mold and make the rest of the products to offset the production costs of the mold etc.

I have yet to see yellowing on the python tubes, but have see the yellowing on the boxes like Mo said. I am pretty sure it was a early prod thing, as they are/were aware of it and paul has stated that they made changes.

We just ordered 4 full sets in for customers, they all look great as far as quality.

So has the yellowing been officially been fixed?
