OK the basics; the force of the piston pushing down on the con rod pushes on the crank shaft = torque. The torque makes the crankshaft turn. So no torque = no revs.

Power is basically Torque x Revs, so no torque = no revs = no power.

So there are 2 ways to get more power, more torque or more revs. To use my favourite expression "Torque is the Father of power and revs are it's Mother.

So when an engine is tuned, the tuner is actually getting it to produce more torque at a given number of revs to lift the power curve up.

Also the bit that everyone wants is acceleration: and that is TORQUE, the wheels push/pull the car forward by transmitting torque to the road as a force through the tyres. The bigger the force the faster you accelerate as Force = mass x acceleration.

Good explaination mate.

But still everyone in the pub wants to know bhp lol

"Power is for show, torque is for go" and like you say BHP is for pub talk and willy waving.

What matters is torque to the way a car feels and more importantly how it's delivered. A "flat curve" with good torque spread across a wide rev range is an engine that will "pull" though the gears. You can change up earlier and still get the engine to "pull", this means fewer gear changes and better 0-60 times etc. Obviously the higher up this torque line is the better, the area under the torque curve is what's important.

So back on topic, this is what the CamCon is supposed to do, give better torque lower down the rev range. In have seen some dyno results that do show that it works. However with an auto box you can't use the extra cos the box will change down to keep the revs up. In my case I really just use it to correct the fuelling as the induction and decat made the engine run lean.

So if you want more power to brag about down the pub the Camcon won't deliver for you.
