Blew SAi AGAIN
« on: 06 April 2011, 11:52:00 »
Hi,

Blew my SAI pipe again.Had to order one in from Vx and wait 4 days last time. Anybody know where would stock one in today?

Or would black electrical tape do the job?

If its the small rubber pipes then its blowing for a reason.....either a centre exhaust section or a cat is blocked.

Hi,

Yeah i think it is the cat blocked. How would i repair it temporary? It has only blew as i have just been down the motorway and gave it a bit of a thrash. Felt very quick and was easily flying past 80 70ish

No easy way as the pressure is causing hot gases to pass through the pipe (which would not normaly happen).

Yes, you can remove the whole SAI system and block the feeds to the manifolds with no ill effects at all. (as long as you leave some load on the solenoid output of the ECU)

But... Where would the gases from the blocked exhaust go then? ;)

The SAI problems are the symptom here.

Yes, it needs cats to meet the MOT emissions limits.
