Removed from my 306 touring car engine and in fantastic condition

These are the smallest of the btcc cams that were made, 10mm lift but long duration

I run these with pistons, rods, flowed head, Solid lifters and throttle bodies

The car was mapped at track & road and it made 235bhp

I have the valve springs to go with them also

Please do not post if not interested

Were the cam's the limiting factor, I would expect to see around 270 with btcc cams, especially if that is infact 328 degrees (with steel crank rods pistons head etc).

I am interested by the way.

You'd need 12mm lift for 270hp

yes, you certainly need pistons, and rods.

LOL Will the pistons need deeper pockets? Smile

No, as the replacement pistons would have deeper cutouts as std...

Are these still for sale by any chance? If so what benefits would you expect with a standard engine and a map or even without them mapped

They won't work in a standard engine without the pistons being changed as they will collide with the pistons.

WP will probably come and correct me now... Wink

Oh okay that was a thought that went through my mind as I've read so many things about clearance issues

I've tried fitting them with standard pistons and it doesn't work by a long way. You'll need cut outs, and I'm not confident that the cut outs that are achieved by machining standard pistons would be adequate so I'd expect to need aftermarket pistons also. My engine made 240bhp with the same cams fitted.

Yes, and you'll need deep pockets too to make good power from natural aspiration.
