Got TT in Greentown next MOnday (31/1). Call Aloy!!

ANyway, the main Advantage of external w/g I believe is boost control. 2nd is exhaust flow.

Disadvantage ah?, "SHRAAAAAAAAAA" sound!! Most people will think your exhaust piping bocor liao :lol:

There is an article on Turbosmart's website which also talks about wastegates. Browse to their site and read the article "Boostin' with the Experts".

Heres something I extracted from the article:
"The size of the turbine and the wastegate really go hand in hand," says Nick. "If you've got a big turbo running high boost you might get away with a small wastegate, but if you run it at low boost you'll need a bigger wastegate. People often can't understand that; by running less exhaust gas through the turbine, you need to be able to dump it through the wastegate. The smaller wastegate is the more ideal choice because - by definition - there's less energy being wasted.

Btw, I'm running a Tial 38mm wastegate on my engine... ;)
