Ben that i know with the white pulsar (his bro is the one on here with the 4x4 cossie mk3 fiesta) has ran consistant 12.6s with just filter, zorst, and bar of boost too.
And to make it even more funny, at a recent RR day (think it was featured in redline) he got the lowerst figure of the day with somthing silly like 230bhp! so 12.6s with 230bhp, pmsl
