okay i'm into performance but somebody school me.

1. what does upgrading fuel rails do.. lik aem fuel rail.. i heard it stops pulsation.. i do know what pulsating means when it involved braking.. like u can feel the pedal pumpin back at u. but how does this relate to fuel...


2. skunk 2 manifold. whats up with that are the ports that meets the side of the head bigger or what..

3. oversized valve.. are the stem longer or the where the valve sit is bigger. sothere the valve seat would have to be modified right?

4. i heard the air the piston suck in is always consistant.. so how does that work.. i think its untrue.. so how does all these upgrades in the cam, valve, and other stuff work in the longrun if the air going in is always the same volume.

 

hey i just got ls and i am ushing my b16 head cuz i have a superchargeer u think that it will last on 5 psi

 

Theres no reason whatsoever to replace your fuel rail until you get into the higher numbers... 450whp or so plus.

Yes the ports are bigger

Yes, head work is required to have oversized valves to fit. The part where the valve sits is bigger. Some people do this when port and polishing their head to help with air flow.

the duration the cam opens the valves has to do witht he amount of air coming into the engine. When you change the cam, you also have to change the valves pistons and valve retainers because the cams are tooa ggressive for stockers. So since the cam opens the valves for a different amount of time, more air gets sucked in.

I believe all of that is right, if not, somebody please correct me. I'm extremely tired, and really cannot think very well right now.

 

if the port is bigger on the new manifold.. how do i get gasket to match since the port on the head is gonna be smaller than the port on the IM..


also my friend got stage 2 cam with springs and retainers and didn't get valves... what would happened... was he suppose to get oversized valves or regular valve but beefier?

what abput fuel pulsation that i hear from the fuel rail..


if i get cams and not piston will it damage it? does that changes compression ratio or no..

 

bump..

What the heck's up with this? noob hijacking the thread?

you have quite a bit of posts to be asking questions like these.

what stage 2 cams did he get and what valvetrain? either way valves arent needed stock will do fine.

fuel pulsation? search because ive never heard of it.

doing headwork (cams, valvetrain, etc.) will not hurt the bottom end (pistons, rods, etc.) while keeping stock redline. your compression ratio will depend on what pistons and headgasket you use and when doing all motor raising compression is a must unless youre aiming for something mild.

 

stage 2 cams and skunk 2 valve springs.. it won't raise the compression at all? even though more air is being sucked into piston?

 

Haha you need to read before you ask questions, no offense but honestly it seems like you don't even know what questions to ask. Read around and figure out at least the basics before you ask questions like this (don't worry, everyone was there at some point, you gotta start somewhere).

the amount of air in the combustion chamber has nothing to do with compression ratio.

you have A LOT of research to do
