Guck dir ma den Thread an, im dritten Beitrag steht dss der lader dadurch schneller hochdreht und auch bei geschlossener klappe nicht abgebremst wird...

klingt interessant

I have found some of the information I have. Most of these throttle bodies infront of the turbo were run inconjunction with normal throttle bodies next to the engine. They were added to reduce turbo lag buy inducing a partial vacuum in the manifold. This did two things: firstly, it allowed the turbo to spin longer and at a higher rpm because of the reduced pumping losses; secondly, the partial vacuum helped accelerate the air through the turbine, rather than just relying on the turbine to pull it through.

The main throttle bodies were retained because the response time to the drivers input was faster; imagine a fast moving mass of air moving through the turbine, the intercoolers and all the manifolds and trying to stop it by grabbing its tail - it takes a while to over come the momentum. It may only be a couple of 10ths of a second but it could just be the difference between catching a 1200hp slide and not! With the throttle bodies next to the engine, the cut off was instantaneous.

Thetwo may sound like they contradict each other but they managed the relative openings quite well enough to see some sizeable advantages, hence their wide spread addoption.

lief wohl mit der normalen drosselklappe am ansaugkrümmer in zusammenarbeit. aber krieg mal sowas vernünftig abgestimmt...

hier ist auch nochmal was

[Jagi]

würd den wasseranschluss ganz Tod legen und ausbaun. mach ich bei mir auch. gab hier auch mL nen thread zu. völlig überflüssig. Ruf dich eh zwecks brainstorming nochmal die Tage an wenns hier weniger stressig ist.

Alsoich habe den anschluss ja noch.
