Big power Zetec

Having finished building and mapping a Ford Zetec Puma with GT30/76 on Emerald ECU.
The engine has been built with Wisco pistons and K1 rods, it has a Sitech ported cylinder head with std black top valves and stage 2 cams. The Puma also has a straight cut box with dog engagement.

Happy with the power 26psi giving 481bhp

So after a late night of car building and dyno testing we have found out the following - 

Car - Bens focus RS fitted with Revo stage 4+ was a 425bhp car, we then fitted our stage 1 cams, the gain was 20bhp neting him 445bhp but boost was struggling to hold 20-21psi due to the new air flow requirments of the cams. Basicaly the standard turbo is now maxed out.

We also fitted water/meth and continued testing this also gained us 20bhp on top of the cams, boost remained the same (normally with water meth you see an increase in boost) but power had gone up another 20bhp.

So end result is 462bhp or 418whp at the wheels. Happy with that.

But the cams also net you far larger spread of torque it hold peak torque for almost 1000rpm longer
Also it makes the same power through out the power curve but continues climbing for another 1000rpm so peak power is now 6300rpm but still same power as old peak at 5300rpm.
