To be honest any saloon packing circa 500bhp is going to feel VERY quick!!
It's all relative. If the car feels out of control it feels fast. Get a Metro Turbo and pull the waste gate pipe off
Seriously though my mate had a Cossie BITD with a T4 (proper one), greys, forged pistons, bd something cams, all those intercoolers and charge coolers and other nonsense. It did 437.5bhp on an engine dyno and similar figures on rolling roads. He wasn't shy about using the power either, none of this "its 440hp but I've got the boost turned down at the moment" stuff. He blew it up more times and had more rebuilds than I can remember. In fact he wrecked just about every single part of the car at one time or another, so much so that it was a Moonstone Sapphire when he bought it and a White 3 door when he sold it
. I'm serious he didn't sell the Sapphire (he wrapped it round a lamp post) and buy a 3 door (well he bought a shell)
. Even the 3 door shell was looking kindof distorted and bent by the end (another crash involving a pavement and some 200 foot skidmarks, on the road not in his pants
). But yeah that was one quick old car, all or nothing power from that T4!!!
