Re: xs turbo question (intekragsr)
Jeeves sucks! hahaha
The difference bw an "on-center" turbine housing and a "tangential" turbine housing is the way that they mount in the engine compartment and the manner in which the exhaust is evacuated from the housing. The "on-center" uses a standard T4 inlet flange, as well as a four-bolt discharge flange. The reason that it is called on-center is just that, the housing sits right on top of the inlet flange.
The "tangential" turbine housing differs both in form and function. The housing sits off to one side, similar to that of a snail shell. The other difference is that to connect an exhaust down-pipe, a V-Band flange-and-clamp assembly must be used. This setup sometimes proves to be more convenient for race applications. The "tang" housings are 4 to 5 percent more efficient in flow. Neither the "on-center" nor "tangential" perform better than the other. The decision to use one over the other should depend completely upon the installation of the turbos in the engine compartment.

Re: xs turbo question (GudeH23a)
If the tangential housing are 4 to 5% more efficient in flow than the on-center, wouldn't the tangential have a performance advantage?
