What's this about a free boost upgrade?

It's true. You can get a 1-2 psi upgrade by removing the boost restrictor on the top of solenoid valve. It is identified by a white band on the hose which goes from inlet pipe to the solenoid valve. This pipe is at the top of the boost control solenoid. If you don't want to cut the hose, just get a piece of 1/4" fuel hose the same length, and replace the original hose with this new piece.

Remember to reconnect all hoses. There is nothing left off or disconnected after this modification. Let me stress this again, There is nothing left off or disconnected after this modification. Take the car for a drive and watch your boost gauge. Make sure there is no major increase or decrease in boost level. If there is, stop and recheck your work!

One or two PSI might not sound much, but remember that the export-spec cars run around 10psi (0.7 bar), this is up to twenty percent, or somewhere about 8-10 kilowatts at the rear wheels. On an S15, we saw 20KW at the wheels. Not bad for nothing!

So, the obvious questions are, why does it work, and will it cause any damage? It works because removing the restrictor changes the pressure signal to the wastegate actuator. From the factory, it is designed to open slowly, and make the transition nice and gentle, by allowing the wastegate to "creep" open a little before we reach the preset boost limit. The restrictor is what causes this creep, by restricting the flow from the solenoid valve. Without it, the wastegate stays shut (or as close as mechanically possible) till the preset level is reached. The opening is now a "snap" operation.

Will it hurt anything? We know of cars which have run this modification for 2-3 years without problems. If you fit an aftermarket boost controller, you generally take the restrictor hoses out anyway. Your mileage and durability may vary.

Niezłe co?

AAHHHHAAA
