Re: [問題] SBK的1098
有人對Ducati凹排氣量的原因有點誤會。
他凹排氣量不是因為跑不過,而是因為雙缸車如果要跑得和
四缸車一樣快,成本太高了。(同排氣量的雙缸車本來就比
四缸車弱,這是事實沒什麼好爭的)
在Ducati 999R和日系四缸車同場比賽的時候,Ducati的廠車
雖然性能很差(馬力差20hp以上),但還能稍有競爭力是因
為比賽規則容許的改裝幅度比四缸車大,但代價就是成本比
四缸賽車高很多。Ducati廠隊撐不住了,才去跟賽會說他們
不要這種改裝的優勢了,999的引擎馬力再榨下去就已經不是
量產車比賽的改裝等級。他們寧願改裝幅度變成跟四缸車一
樣,換取200cc的排氣量,然後還要裝50mm的節氣門限流器,
而且賽會覺得比賽不公平的時候還可以隨時把限流器直徑改
小。
有改過車的就知道節氣門對馬力的傷害有多大。直徑50mm的
節氣門有多小你知道嗎?連GSXR600的原廠節氣門截面積總和
都比它大…
