Say I did get a 1.0 or 1.1 exhaust housing. If I threw enough fuel at it to get it to spool would it still surge ?


I'm not totally against a ratchet shifter with a switch for od and a switch for lock up.

I'm going to wire up that switch that was posted to keep it out of overdrive longer and also play with the fueling some more. I'll buy a larger exhaust housing last.

I think with the larger housing you will still struggle with surge issues(it will just be laggy so it won't be as noticeable). I would almost say put a smaller housing on it with an external gate so you could driver the turbine hard enough all of the time to prevent surging.

Of course I might be misunderstanding, but the best way for me to comprehend the issue with surge is the turbine wheel doesn't have enough HP to overcome the resistance from the compressor side.
