Eventuri FL5 Turbo Tube/Inlet Pipe

[blueroadster]

The Eventuri turbo tube is an engineering work of art. Here is the weight of the tube itself before adding thermal protection that will cover all of the eye candy:

I really appreciate the FL5 having a front mounted turbo. Upgrading my previous FG2 Civic Si required a lot more work for thermal management given the rear mounted turbo configuration.

Question you going to wrap certain parts of the inlet or the whole thing? Also I was thinking on doing something similar to the oil lines ay the turbo, it’s will reduce temperature or just heat transfer will be less? Because I was thinking on installing the 2 oil coolers that airtec motorsports offer the one for the turbo and the one for the engine. But my car is daily I don’t even go to track at all but drive the car 2 hrs in traffic in the Texas heat. Also which gold tape you use? Just want the car to be reliable on the long run I know it will be but I want to prevent any failure points that can arise in the future.

As can be seen in the following PIC, the turbo tube already has some thermal tape on the bottom.

I'm wrapping the entire part. The thermal tape is DEI Reflect-A-Gold available in various sizes (https://www.amazon.com/Design-Engineering-010394-High-Temperature-Reflective/dp/B0039Z5TUY).

Application of the tape to a part reduces thermal heat absorption from nearby radiant heat. It is inexpensive, effective and has been proven for decades. If you have flexible lines, DEI also has heat shroud sleeves.

IMHO, the factory turbo tube functions as an unnecessary heat sink. Thermal heat transfer to the air moving through the tube may be minimal, but the tube itself is still a heat sink. I decided to go with the Eventuri turbo tube not for the price but because of it's design.

Thermal tape (8 grams) removed from the Eventuri Turbo Tube resulting in 358 grams for the tube itself:

Added 52 grams of Reflect-A-Gold (1 -1/2" wide split in half) covering the entire tube (410 grams total weight):

The tight bend near the turbo inlet connection required several cuts in the tape to pull tight and conform to the curvature. The start and end points of the tape in that area are hidden underneath. Applying a little Testors clear enamel model paint to the start and end points of the tape will ensure that the ends of the tape do not delaminate over time.

All this thermal stuff seems excessive. DEFINITELY for anything short of intense track use in hot climates... and then probably only justified for an aftermarket turbo. No one needs to take extra precautionary measures to just sit in traffic, I'm pretty confident about that.

Also while you'll never hear me argue against having too much data... isn't it kind of silly to worry about 8 grams... or even 52? That's literally the difference of eating all your fries for lunch or stopping when you're full. Or what fabric you choose to wear. Or what case is on your phone. Or how many Altoids are left in the center console. That little hoodie that goes over the shifter probably weighs more than 52g. Lol.

The tape looks pretty cool if that's your thing (I prefer the raw carbon), but I really struggle with the thought that all this tape and wrap actually serves a true functional purpose for the vast majority of use cases outside pure racing settings... and I'm guessing more often than not, actually makes things worse.

But contrary to most people on these forums, I like to be proven wrong because I like learning new things; would anyone care to combat this assessment?

Weights were shown simply for comparison to the part that it replaces. The factory turbo inlet is a cast aluminum part that sits right above the turbo and functions as a heat sink. Those that replace the part with an aftermarket one are not doing so for weight reduction. A primary benefit is less restrictive airflow to the turbos and a secondary benefit is getting rid of the heat sink.

Replacing the factory turbo inlet will not solve any overheating or heat shedding issues. In those instances, one should be looking at replacing the stock radiator and intercooler as a start.

Personally, I like the carbon fiber look of the turbo tube. What I don't like however is that the weave pattern does not match other carbon fiber parts that I have. Given the close proximity of the part to the turbo assembly, there is positive benefit to adding thermal protection. I opted to go with wrapping the entire part but understand that may not be everyone's cup of tea.

Around the turbo assembly, there are many areas where thermal protection provides benefits in either containing heat or reducing thermal transfer. Shields, coatings, blankets, etc. on the hot side of the turbo and downpipe exist for a reason. There are also other areas that could use some attention such as the factory turbo inlet (replaced in this case), the hard water line section, throttle body inlet tube, etc.

You look the motor out of your fl5 just to wrap those lines?

No, that PIC was from my previous build (FG2). The motor was replaced with a K20Z3 ERL sleeved block with a stroker kit, headwork, and a bunch of other stuff. The turbo system was a custom one-off setup that I worked with Full Race to have designed/built.

A lot of thermal protection was needed in that particular car because of the rear mounted turbo configuration and tight space. Initially, I had the turbo manifold, turbine housing, and downpipe coated by Swain Tech but there was still too much heat radiating to the nearby brake lines and harness. That necessitated having to add thermal protection to those areas as well as wrapping the header and downpipe. The compressor housing was also modified by Full Race to clock a custom elbow connection.

Here is a video after the car was completed and tuning done at Evans:

For this scenario, yep it makes sense. You're adding way more heat than was originally engineered for the car. It is/was a very cool setup btw.

For the FL5, unless you're doing something similar, feels like overkill to me.... and while I don't have data on hand to back it up, I'm pretty confident that in some cases arbitrarily adding thermal tape/wrap has had the opposite effect and made things worse.

As for the weight stuff, I disagree- (almost) no one is swapping out the inlet pipe for weight savings. Again, it's the rough equivalence of the difference between a happy meal and a big mac combo (not sure why I keep defaulting to fast food...). I went with the Infinity Design setup, and while initially I was going to skip the inlet pipe, I saw pictures of it and decide hell yeah, I want to look at that when I pop my hood. I've seen at least some compelling data that there is an actual performance and/or sound benefit as well but I'm not here to argue that- I just like the way it looks and could care less about the 4 ounces of weight it saves... and admittedly think it's silly for anyone to think that amount of weight would make any tangible difference.

You should gold-tape your whole Infinity intake/inlet, it would look so "COOL" Get it ?

Please don't do that. If I had the Infinity setup, I would have simply installed it as is. Instead, I went with the Eventuri Turbo Tube and GruppeM intake. They are both carbon fiber but the weave is different.
