explaination should seriously go in your sig

fxcking a+ for explaination

 

thanks everyone

I was going to but dont know how to get the quote in there.

Its says i have to many characters

 

 

erm, sorry to be a kill joy but that explination isnt exactally correct. a k03 putting out 20 psi at 3.5k rpm will give the exact same HP as a T3/T4 putting out 20 psi at 3.5k rpm. the reason you get a crap load more power is that it holds that boost till the end. the straw is partly correct, but no matter howq big ur straw is, 20 psi at a given RPM is still 20 psi. the bigger turbine gives it the ability to keep that pressure longer. so again, 20 psi at any RPM will give u the same power no matter what it pushing it in. its just what RPM that boost is schieved at.

 

^^ agree with that

 

i think we are getting close but not exactly correct yet. 20 psi in a manifold regardless of what turbo you have is the same amount of air IN THE MANIFOLD. BUT, if you increase the flow of air out of the manifold you need to increase the flow into it to keep a constant pressure. So even though the pressure is the same, the cfh (cubic feet per hour) of air going through it is different.

 

woops, i might have been ahead of myself. engineers do that sometimes. so what actually controls the flow of air into the manifold is the speed at which it leaves. what controls the speed of air leaving the manifold is the volume it has to go into next. that would be the volume in the cylinders. so if the timing or compression ratio are not changed the amount of air into the cylinder is the same for either turbo. BUT when you start getting into high revs, the cfh of air goes up since the valves are opening and closing more times per minute.

so, a bigger turbo that produces more cfh of air can keep the boost at 20 psi longer.

so in the end, all i did was explain Audicross's answer in more detail. sorry Audicross

 

Right. The Chipped k03 runs out of steam at 5K and the pressure and CFM drop. The larger turbo pushes more CFM and is able to keep the pressure up higher in the RPM range.
