can turbo heat crack CF hoods?

[Shpyder]

I was looking on ebay and I found a used carbon fiber EvoIII hood with pics. Used, in ok condition, $300. They guy says it looks perfect, but there is a hairline fracture on the hood due to the heat his turbo generated. I am innterested because the hood is only 40 miles from where I live (save the insane $150 shipping).

How much of a effect does the turbo heat have on these hoods? I have never really thought of that. There are brand new invader and other hoods that this guy sells in LA for $385 out the door, BUT its 150 miles north of me. Should I go for the hood, wait, or just forget carbon fiber hoods all together if they are bad with turbos?

It depends on your setup, how big and how close your turbo is to the hood. If you're using a stock turbo (concidering the fact that I'm picturing exactly where it is) there should be no problem at all. Now, I've never heard of anyone cracking their CF hood around my way with a 16G & under. Another thing to help with heat is a turbo wrap. Yes I know.. they look like something on a space shuttle but it keeps the heat out of your engine bay a long with using the heat tape on your header. Trust me bro, you'll be fine. I dont think anyone will disagree with me on this one.

Well, this is going to sound incredibly stupid, but the turbo I have is a "modified" T-25. The shop guys custom made it. It spools at 4K and pulls rediculously hard (though the lack of a larger exhaust noticibley chokes it at higher RPM), and uses the T-25 housing. Could be a T-28, not sure. But yeah, basically, its no 20-G, if thats what you mean. And the heat wrap... can it actually withstand the heat of the turbo??

yes even stock can crack CF hoods i have cracked 3 one was with the stock turbo i went VIS this time and so far so good

[Shpyder]

Youve cracked THREE CF hoods? Are you serious? After how long did they crack? Is ViS any better?

this one i had dont know the name but i lasted for 8 months i was pissed. The 2nd was from a local shop again i have no name lasted right under a year. 3rd Needed a new one and cheap so i got a hood of ebay lol yea 3 months. so i was like fuck it called VIS and asked them if there shit was good and told them my prob and they said it was good some kinda heat treating or some shit i have had it for over a year now. NO cracks i love it it's also double sided:-)

stock hoods have the tin-foil lookin' heat shield on their under side. the cardboard-foil type, u know. would that make any difference?

[mitsu_eclipse95gst]

huh maby i did not even think of trying 2 put that on. good thinking!! it's well worth a try!

[1stGenRocks]

yes that sheild will definately help.

I am not using any type of heat sheild. I am also using a Vis hood, and it's held up nicely. Has pulled away slighty by the valve cover though.
