these boys who are running 300+ are they one big turbo or a twin turbo idea like the bmw 335/535d ? as i can imagine alot of lag with one massive turbo ?
Don't think anyone is running sequential turbos although there nay be a polo that is.
I'm not running 300bhp in my Ibiza but I'm told my turbo is capable of it and it's making boost earlier than my old hybrid. And holds it longer too.
I don't kno of many cars running over 300 that don't either have nitrous, propane or both
