Ide like to take this small amount of server space to give props to Tial for a great product. ive had my tial bov for a few months now sitting on my desk. i took it apart to check out its inner workings, and its the most well desinged bov i have ever seen. the piston bolts around a diaphram (sp) that is held in by the two parts of the housing, making a perfect seal. just a week ago or so i finaly got to experance it in action. my buddy got one for his mr2.

it has a very percice action and holds boost or spool or what ever between shifts a lot better then the GReddy type S it replaced.

and for you sound is most important in a bov people. it sounds awsome. kinda like a squiel followed by a whoosh.

highly recomented part
