clocking turbo Options

[Mr_chOps]

hey guys...im planning on getting a st185 clip and i was just wondering...if i clock the turbo what dif. does it make?? does it improve on performance?? i no it uses less IC piping rite??

The exhaust gasses may be, but the intake air is not. Every little bit helps.

Besides, I heard once that each 90* bend is equal to like 3 feet of piping... if that's true, eliminating a 180* and a 45* bend from the route the intercooler has to take makes a big difference.

The intake air is not in the loop that is eliminated by clocking the turbo either.

I do not argue that running a more direct route is generally better than a route that has 180 degrees of more bends. My only point is that the improvement is marginal at best.

Yeah it is. What in the world are you talking about? That loop is the air that just came out of your turbo and is headed to the intercooler and then through your engine.

There isn't a massive improvement though, that's true. It just looks a lot cleaner and functions a little better.

Doc: I understand that the air coming out of the turbo eventually ends up in the intake. My point was in response to your statement that the "intake air is not hot". Its not hot because it is cooled by the intercooler. The air in the loop coming out of the turbo is the same temperature as the exhaust gasses. If the turbo is clocked and the loop is not there, the temperature from the turbo to the hotside (passenger side) of the intercooler is also hot. Eliminating the loop does NOTHING for intake charge temperatures.

The reason it functions "a little" better is because the elimination of 180 degrees of turns.

I am not trying to argue here. I think we both know how it works but I wanted to explain what I meant.

LMAO. The temp of the charged intake air coming out of the turbo is in excess of 800 degrees??? You better do some more research before you start trying to argue turbo theory with me.

And it's a 180 and a 45, just to be clear.

I made a mistatement in this thread when I suggested that the temps in the manifold were identical to the temps directly after the turbo.

With that said, you missed my entire point. Are you really saying that running that loop over the manifold impacts intake temperatures when a decently efficient intercooler will take the temperature down to near ambient? I won't be so disrespectful to suggest you do more research but I will say that if you think that then we just disagree.
