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??

its mostly for looks, and a little less ic piping having to be run

My car became much more responsive....or could that be because of the new turbo?

Actually, I agree with Art. I think its funny how people think that intercooler piping makes such a big difference. Its much more important to have a relatively smooth path - particularly before the intake manifold.

By clocking the turbo you remove a 180* and a 45* degree bend from the piping. That does make a difference, not to mention that you don't have the intercooler piping looped over the hot exhaust manifold.

thats what heat wrap is for!

i will probably clock mine at some point, just to have a cleaner look. the only hard part is trying to fab up a bracket that would work well for the actuator.

Thats the hot side of the intercooler. The exhaust gasses are just as hot as the manifold at that point anyway so looping it over the manifold makes no difference.

[Dr_Tweak]

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.

thanks for the responses guys. im probly just going to leave it stock and wrab the ct26 with heat wrap or something..THANKS

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 dont think any one can say what benefit or drawback each way has, unless they tried it bowth ways on the same turbo/engine. i might clock mine when i take my motor out again this summer, but i dont really expect any huge gain from it. just more for a cleaner look.

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.

thats what heat wrap is for!

i said it once, and ill quote it again ! haha

LMAO. Art, you kill me man! You going to weigh in on this debate or just bust my balls about the heat wrap?

[lagos]

i thought we needed something to break the ice

[jgreening]

fair enough.

[presure2]

i gotta agree with jay on this one.
with my setup, all i have is one extra 90 in the loop. (i didnt go around the bumper with my hot side piping, i went thru the rad support)
even after hard boosting runs, you feel the cold side, and its cool to the touch.
