you will have a pipe that goes from your intake plenum, or intake pipework to the actuator. all you need to do is fit the bleed valve in that line. there will probarbly be specific in / out connectors on the bleed valve, so make sure you plumb it in the correct way round

Bleed valve is a good way to kill a turbo. What you want is an MBC (Manual Boost Controller).

looks like i have a mbc anyway......

All I would say is ..... be careful. If you get it wrong then boost levels go sky high with inevitable results.
A proper boost controller is the only way imo.

OK - If you want to use one of these you need to buy a turbosmart valve. This works on a similar principle to boost valves but is much more reliable and consistent. It doesn't bleed the plenum to actuator feed it holds it until the dialed in boost level is reached. This 100% eliminates any wastegate creep and bounce and means you can use a low rated actuator with higher boost.

I have been using this for two years on my pinto turbo and I have one click setting to move from 8psi to 11psi held. I know some of the boys on turbosport are using them up to 2 bar plus so they are very versatile. Just be disciplined and don't go too mad. I checked mine with a RR session to check I wasn't leaning out.

Can't recommend them highly enough!

Otherwise known as an MBC

Also known as: PRV (pressure release valve), Dawes device, Grainger valve, G-valve and probably a few others as well!

greddy profec B (the early one) was the best Ive ever used. In car adjustment and dual boost levels.

the later ones were mad tho, need an ALevel to set them up.

definately get a boost gauge if you dont have one.
