wastegate?

[NBowlin]

i am completely lost on the wastegate deal... is it better with or without? and since there is never just an answer to something like that what are the pros and cons of wastegated v/s non.

thanks

A wastegate is essentially a valve that bypasses exhaust gases around the turbine.



This limits the max speed the turbine can achieve, and therefore limits the peak boost the turbo can make.



Wastgating is necessary to limit turbo RPM, and boost pressure on turbos with smaller exhaust housings that are used to lower spool up time of the turbo. The wastgate allows the turbo to "swallow" a larger volume of exhaust gas without sending the turbo into orbit.

Here's a good little article on wastegates-

IMO the wastegate is a good thing that shouldn't be disabled except for the folks who race or sled pull their rigs.
