I have a 2004 RSX Type-S w/ Comptech Stage 3 Supercharger Kit.

I went to the movies last night and the car was running fine. Driving home from the show I noticed I had no boost. My boost gauge is reading vacuum and when I step on it it will read 0 boost but it never goes into boost.

This morning I popped the hood and took a look. I dont know if this is normal because this is my first blower: When the car is off the boost bypass valve is closed. As soon as I start the car it locks open.

Edit: After doing more research it is normal for the bypass valve to be closed when the car is off and to open when the car is at idle. But for some reason when I step on the gas I dont think the by pass valve is closing back up.

vacuum leaks or belt loose or gone?

where is your vacuum sitting at in idle? steady?

I'll check. I had my girlfriend rev the engine while I watched the actuator on the bypass valve. It is opening and shutting which is even more curious.

Im going to go hook up to the kpro now and see if I am throwing any DTCs.

EDIT: K-Pro is not showing any error codes.

For me (Turbo) a little hose clamp poped off the intercooler. It was under the turbo, so it took me like 30 mins to finally find out where a leak was coming from.

sounds like your wastegate is stuck open

:eek7:

come again? this is an sc. i assume you already know why a wastegate does not apply on an SC ;)
