Worst Intakes = Carbon Fiber

[m3f_toopercentmlk]

hey guys, are those budget intakes and CAIs on ebay and some cheaper company sites worth the $50 or so that they cost? im thinking about getting one that looks like it will work and fit right. anyone hav one of these budget intakes?

Gruppe M is the bomb! One of the best companies I've ever come across. Love their product, not to mention it looks awsome too. :rockband: :thumbsup:

Check out the FAQ for a huge thread on intakes.



Also, when you are actually driving, the air spends a whole .05 seconds in the intake tube before the engine uses it. So using that theory, how much heat do you really think will be absorbed from the tube. Well, probably not enough to ever make a difference.



As long as the filter has access to cool air, the intake will work just fine. So use one that goes down into the bumper, or one that sits behind the headlights with a heatshield.

Have you ever seen race teams use Carbon Fiber Intakes?



Carbon Is used in solar cars to conduct, welding electrodes etc.



Carbon CAN BE manufactured to be an insulator or a conductor. But normal carbon parts are an excellent conductor of heat and electricity.



If you used a piece of real carbon as part of a circuit the light or whatever it was powering would essentially turn on, as carbon is a semiconductor and graphite is also a conductor. :thumbsup:

hey bulla what does that intake give you in the way of hp?

gruppe m qoute 18 bhp which i is wishful thinking.I got about 9bhp which i think is still good for a n/a engine(and it looks and sounds the bollox)I LOVE IT

In solid propellant rocket motors, the nozzles/exit cones are just about always lined with composite materials, and in different applications have been combinations of glass epoxy, silica phenolic, graphite epoxy, carbon phenolic and carbon carbon. All keep the heat of the exhaust gases off the metal cases, although they all erode to some extent. Some exit cones are made entirely out of carbon composite. The throats are made out of carbon carbon which can handle 3 to 4 thousand degrees. So yes, they are all good insulators.

As to the practical situation of how much engine bay heat is actually ending up in the cylinders, you really have to know air temperatures and velocities on both sides of the tubing to begin to calculate the temperature rise. Without that I would say it is just guessing. My guess is the incoming air picks up inlet manifold heat more than engine bay heat. What do you guys think?

I think you are getting water and xenon gas mixed up... what?



H2O is not good at conducting heat or electricity



On a side note.. not sure if I'm digging these new boards... I guess it's just different



Yeah, water isn't good for conducting, but to convect it is much better than CF. I meant in comparison to his CF statement, water would be better than CF would at those jobs, but if you're referring to everything else in the world.... :thumbsup:
