Before I got my car mapped I was regulary getting low 13's @ 106-108mph
I am now getting low 12's, well 12.40 @ 111 mph does this sound about right and what sort of bhp should i have to get those times.

It could be any BHP to be honest with you. All depends on launches and gear changes.

Mine has about 425 BHP but because I have only done a couple of runs in the Skyline my best time to date is 13.26 @ 108MPH IIRC

Whereas Milko, who was running standard boost and exhaust and filter was running very low 12's with about 340HP ish.

get your car on a RR to see the BHP.....

P.S. Where in the NW are you?

I suppose another thing to add to the mix is this hot weather, just cant beat a cold fresh winter's morning
