Lindsey Racing "Smart Shim" 944T Wastegate Shim.
|
Wastegate "Smart Shim" for the 944 Turbo Wastegate. The
first and only wastegate shim that doesn't require
removing the diaphragm pot to install. Just slide it in!
Shims are 1/16" thick and made from stainless steel. You
can stack from 1 to 3 in your wastegate to adjust your boost. We don't recommend more than 3. There is only
1/2" of valve travel in the wastegate. If you install a
1/16" shim, you lose 1/16" of that travel. So 1/2" of shims would keep your wastegate from opening at all.

Q: Is there an accurate number for the increase in boost for each shim used?
A: If you want to raise boost, you're best to use a boost controller. The shims work to bring the boost in a little earlier.
