Thread: Supertech over sized valves & N1 Cams

please explain to me why then do ALL 3 valve engines have 2 intake valves and 1 exhaust valve? also why do ALL 5 valve engines have 3 intake and 2 exhaust valves?
hmmmm

What you are saying has nothing to do with density. Just because the intake ports are larger you this k this means the intake charge is more dense. No the reason the exhaust ports are smaller is because The general rule is you need 25cc ex for Evert 100cc intake. The exhaust gas has a higher velocity then the intake. Also has much higher pressure...thus you move a lot more velume through a smaller port..

you just proved my point that intake valves need to be bigger.

Depend on where the N1 are installed. Straight up @ 0,0 no problem, but if you push the exhaust past -5 I would see a problem since the +2mm oversized exhaust won't fit in the stock piston valve relief.

Will be using stock cam gears, as mentioned in my first post.
It has been well debated that 0,0 is the best setting for N1's.

Really? You think 0,0 is still optimum when you start installing bigger valves and sinking the valve seats after the valve job?

Well shed some light please.

That was never why cory commented on this, nor why he continued to explain. He is specifically talking about the density of the intake charge, correcting your statement. Never did he say anything about the intake valves needing to be smaller than the exhaust.

Having a discussion with you is pointless, I found that out in the thread about using a de ecu on a ve swap until the guy could get something better. You take something someone says and change it, twist it around in your head so that you can say they are wrong.....

Thank you

Technically the intake charge is more dense being at a lower temperature than the exhaust but I too have no idea what he was getting at.
