WE INVESTIGATE HOW TO TEST YOUR BOOST SYSTEM TO MAKE SURE EACH AND EVERY PSI IS REACHING THE COMBUSTION CHAMBER
Welcome to the Weekend Workshop, a place where you can save some cash by getting your own hands dirty. These tech guides aim to arm you with the necessary info and knowledge to get out there and give it a go yourself — no professionals needed — and at a price that won’t break the bank. This month we delve into the world of boost leaks. This often silent thief has been robbing many performance car owners since the first turbocharged car came off the production line. Perhaps you just completed a turbo conversion, or added in a boost controller, or you have an old factory turbo car that’s lost its puff. This very quick diagnostic method is simple, foolproof, cheap as chips, and nine times out of ten the fix is as simple as tightening up a rogue hose clamp. If your car is leaking boost, then your turbo will be working overtime attempting to compensate for that loss of pressure. If your car has an air flow meter it will have accounted for that air coming in, causing an over-fueling issue. If it’s MAP-based engine management, then both the injector cycle and timing will be out, all of which are robbing you of those precious kWs. Who knew it could all be so simple? You’re welcome.
