What did you do to your Integra Type S today? 🙋🏻‍♂️

I stand by my earlier comment about not knowing what is wrong w you but I'm into it

Interesting, I went with CF cause it doesn’t absorb or transfer heat as much as metals (and it matches the engine cover). But I know there's down sides to CF too, oxidation, strength etc.

Ti is extremely efficient at shedding heat at the surface and does not transfer well (ti brake shims for example). Carbon can be efficient if it's built with the right resins, but it acts differently as an insulator. Once carbon (resin) is saturated with heat it won't shed it well and the resin will break down over time. There are resins that can handle 250C and some that can go even more, but those are really pushing the envelope and not cheap. Think aerospace application stuff. They still heat soak and fail over time.

Exactly. Contrary to conventional thinking, you actually want a good thermal conductor for the core material so it can shed any heat it absorbs quickly, and then you want to shield it from as much radiant heat as possible to reduce the thermal inflow side of the equation.

So I'll be doing what I think you did and put gold wrap on my Ti inlet, and I've already done the turbo and downpipe blankets which keeps as much heat going out the tailpipe as possible.

Luckily the ti pipe is round so it's an easy wrap job, unlike the pita circutangular oem pipe!

I’ve never heard of such a shape

There’s a story. Pilot of a sr71 got its throttle stuck. And the plane either touched Mach 3 or Mach 5. I forget which it was. But it took about 30 seconds for the pilot to do a thing so the throttle would take his commands again. Thusly allowing him to slow down

any other plane would’ve been ripped to shreds. That friction is too much. However, the sr71’s exterior. Being all UWU as fuck. Was titanium! The pilot and crew believed if not for that they would’ve been dead.

titanium doesn’t like to yield and bend. It’s a very hard metal. But it sure can take and shed tons of heat!

Titanium does not bend but when it does get compromised it will crack or shatter. It doesn’t do well with constant temp changes (extreme heat/cold) and over time that does make the overall material more brittle. As for heat expulsion, i can’t speak to that.

U ever see the underside of an a10 that got to hang out in the Middle East from 01-05? The whole titanium underside is so banged up from enemy bullets and rpg’s.

the pilot sits in a titanium bathtub looking cock pit too. To keep them from getting shot

The real issue with titanium is that it has a fatigue lifespan. So even a properly engineered structure (ie does not stress past yield) will eventually fail from fatigue/heat cycling where other steel alloys won't. That's why Titanium has longevity issues in exhaust systems.

It's a classic problem of pick the right material for the application.

Yup. Learned this in my Subaru phase. Titanium does make for a better hollow type sound but all of those welds need to be inspected yearly and spot mig what needs to be spot migged. Titanium exhausts aren’t long for this world. The structure weakens due to heat cycling. It starts taking on these cool looking stress fractures. Then it breaks piece by piece.

Finally found the source of a very annoying 2500RPM rattle I was getting from my engine bay. Turned out to be the engine cover - the upper left bolt, even when fully tightened, was not fully securing the cover to the motor/harness assembly and had about .25mm of play in it.

I've ordered some 10x16mm rubber washers to install between the bolts holding the cover and the cover. For now I've removed the cover and the rattle is gone. Will report back once the washers come in whether this solves the problem.

Anyone else had/have this issue?

It doesn’t look horrible with the red logo….. I guess….

 

[Ash @ S2i Audio]

noooooo paint it blaaaaack

Unfortunately, it does look horrible . And it will look even worse once it ages. I just had mine installed a few days ago and had to remove the logo.

Dammit……

the logo doesn’t spark UWU. At all. Absolutely unfuckable
