一般量產車用的進氣管路都是塑膠製品,這類製品用在na車上是沒問題的
但如果用在turbo車上,當渦輪開始作動時這時排氣葉片會帶動進氣葉片開始吸入大量的空氣並壓縮後進入intercooler,
而此時進氣端需要更多的空氣並且會形成負壓狀態,這時如果是塑膠製的管路,那就會產生變形的狀況,尤其壓力打越高,
塑膠進氣管被吸扁的機率就越高,所以一般我們看到的改裝品都是金屬的原因就在於此,當然還有另一個原因就是當渦輪改大後,所有角度及位置都跟原廠不一樣了,所以用金屬管重新製作是最快最方便的.

Well said.

For those who are worried that the aluminum tubing may trap heat. Don't be......It will not affect or impact performance to any noticeable degree due to the high velocity the air is traveling within.

Of course, it doesn't do any harm if you decide to warp it up with heat blocking material. It's just may not be the highest c/p mod IMO. Not to mention it looks ugly :)

So, should I need the tube too?

請問一下，
350RS的渦輪，是用幾號來計算嗎？

I don't know what turbo "number" are often refer to in Taiwan. The chamber size has been increased to K06 if this is any help.

Howard,

Do I need the aluminum tube too? Where I can get a better price from? PM me when ya free bud!

幾號是台灣粗略的分法用三菱TD03,TD04,TD05分,可是光TD04就有很多種產品,
外國較常用到Turbo size是A/R,出風口面積/蝸牛殼半徑(出風口中心至進氣葉中心)

Jiaching, thank you for the information. Now I finally know what everybody is referring to these turbo numbers ...

還要弄什麼鋁管？

其實用渦輪殼的AR來看也不準...
用渦輪葉片進氣端的inducer/major還有排氣端的exducer/major的直徑來看比較客觀..
舉例來說...老美蠻常用的T3/T4這顆老螺...外觀長的一模一樣...對應馬力卻可以從250匹到600匹不等..
差別就在於葉片trim不一樣...
