Just had a question. i read somewere dont remeber were but it stated that using same size valves on a turbo engine gives it more power. like the intake and exhuast valves the same size... anyone have anything to say about this ?
yea that dont sound rite. but i cant say for sure

In a turbo engine, the more air you can get flowing through the engine, the better. This probably comes from the exhaust valves are usually smaller than the intake valves as far as I remember, so putting bigger valves in would allow you to make a bit more power.

biger valves more power yes, more air flow more power yes, but evenly sized vavles don't factor into the equation.... thats liek saying VW 1.8T is bad engine cause the head design... 3 intake valves and 2 exhaust valves per cylinder, all that matters is the air flow, doesn't matter how you get it... are you sure he wasn't referng to the cam? alot of turbo profiles on cams are close to even duration and lift from intake to exhaust side.. with very slight overlap if any
Check out the I/E valve ratio post I made recently. MadJack brought the point that the air/fuel charge has different densities before and after combustion, so the exhaust doesn't need as much room to exit...greater density

i don't know for a fact, but wouldn't it make sense that the exhaust gasses would be greater because with heat, you get expansion, the cold ait coming into the combustion chamber would be more dense... any thoughts?
theres more to it then heat... your burning up whats in the cylinder... bad exmaple but think about it this way... whats needs more space... alog going into a fire, or the ash thats left once the log burns...
