I have a chance to play around with some carbon fiber this winter and i was considering making some charge pipes for my car. However i just cant make up my mind if they will help or hurt.

Some local cars have aluminum piping. Theyre explaination is that because it transfers heat it can cool itself off.

However i would think due to the heat in the engine bay that it would be better to insulate the pipes from the heat, expecially when the pipes are near the turbo or after the intercooler.


what does everyone think?

boost4life

id try doin the carbonfiber , ive never heard of someone doin carbon fiber , and it's prob would be better 2 insulate jus my 2cents id def like to see it when ur done

If you look hard enough you can find some people that have them. I know synapsemotorsport.com made a set.

cf doesnt transfer heat...helps keep the IAT's down after the turbo....good luck gonna be kinda pricey

MAFDARK

?? i know it doest transfer heat. but do i want it to?

you didnt answer the question.

Its fairly simple. If your under the hood temps are higher than your IATs post intercooler, use carbon fiber. If your under the hood temps are lower than your IATs post intercooler, use aluminum. I'd also suggest coating/wrapping your exhaust components before doing the test.

No you dont want any heat going into your motor...the cooler your IAT's are the more power your capable of making.

So um what kinda amps you use on your tig to weld flanges on carbon pipes?

so do you think the engine bay is more often warmer than the air in the pipes?


lol at midship

With EL manifolds, big downpipes, big turbos, and big FMICs, often your under the hood temps will be very high. Possibly higher than your IATs. You need to do testing on your specific application to know.

You should explain the full reason why nowtype, carbon needs to be cured at the temps its going to experience, correct me if I'm wrong.

reasonible enough. I was hoping someone would sway me to think one way or another. I guess ill just have to wait to get the beast running and rig up some sensors.

I know very little about carbon fiber. I'm speaking as if carbon fiber is a superior insulator to your average stainless steel. If it is not, then just use stainless and be done with it. As for the reason why under the hood temps can be higher is very simple. FMICs block natural air flow to the engine bay. Turbo systems with EL manifolds, big DPs, and big turbos act like huge radiant heat sources. The heat is just going to build up in the engine bay due to said poor air flow increasing under the hood temps. That is why it is so necessary to thermal coat all your exhaust components if possible. Not to mention it helps the actual exhaust performance by keeping the temp in, it increases the exhaust's energy as heat = energy. Heat loss = energy loss.

like i said, hope you got some dough...and its a special carbon/carbon welding rod that does the welding...haha jk jk...but i think your right too midship on the curing process...and carbon fiber IC pipes will just be a huge baller status and will prolly make a huge diff in your IAT

i have the cost covered....im making them for free lol.

I love my major.

Then by all means, do it.

Honestly, if you want to have low under hood temps... lose the hood.

MAFDARK

ill do some tests to see if its worth it. I dont want useless carbon fiber bling. Also for the class, i can make something, but it needs to be usefull or I fail.

Dude I've seen cylinder head ports with i liner of carbon fiber..( F1 i believe has done this Dont know who but it has been done.. Charge pipes Not to sure if it would help but i know aluminum should compared to steel...

Haha exactly, what do you plan to do for the BOV flange? And if your gonna make em yourself, put a lip on the edges of the pipes so they wont blow off the couplers. I dont know if CF would be more prone to this or not, but it wouldnt hurt. If you do a good job they'll look cool probably...

MidShipCivic

Acutally he can use a flange and use aerospace glue to seal it no boost will break the seal.

Aerospace glues are no joke dont let your friend glue you to the floor you wont get out of it!


Orrr for the section of pipe he can use just a small aluminum section slip fitted over the carbon or under it.

IRONlung201

For real, Glue? They got stuff strong enough that can deal with engine bay heat? But the glue is gonna ruin the "Bling Bling" of the CF pipes

He could also mount the bov on the intercooler, full race backdoor style

MidShipCivic

They have glues for just about any situation you should reasearch it.

This is stuff you wont find at walmart.

MAFDARK

I will simply mount the blow off valve on the intercooler end tank. No glueing

I'm assuming you tried this?
