BHP and Torque
thepest - 14/1/10 at 11:35 PM

Anyone got any BHP/ torque figures of a xflow running a 244 cam? IE peak torque and peak bhp?

And does anyone know how long a piece of string is?
More info dude. Like capacity for a start.

Ooh, ooh..me Sir... I know that one..

Twice as long as half its length

Well, that depends on how long you cut it doesnt it?

ok guys it was late when I posted:

I'm talking about a 1680cc xflow with the big valve head setup & a stage 3 ported head.

approximately 40m - i've got a photo on my phone to prove it

The state of the head and design of the exhaust and inlet manifolds makes a massive difference. The 244 could make up to 150 bhp if the head has been properly ported with big valves and the exhaust and fuelling are up to the job, but it definitely won't make a nice road car.

Pretty much what I was thinking...

Guestimated figures are pointless IMHO. More importantly is ow it drives; does it pull like a train right through the revs with no hesitation or flat spots, does it have a detectable "on-cam" power band etc.

a quick run up on the rollers will give you a power vs torque curve and show you how well it's working and where improvements could be made. Even then, the actual RR figures are a little arbitrary it's the shape of the curves and the way it drives that matter - all IMHO of course.

Very much the latter, with 290 degree duration it's never going to be a stump puller! Kent suggest 3000-8000RPM power band, but will obviously be dependant on the rest of the engine.

NigeEss and A! get a pass, speedyxjs and MikeR get a fail.
speedyxjs, because if you cut the ends off, it becomes infinitely long.
MikeR, because I wasn't talking about that piece of string. Never make assumptions.
Good effort though boys.
