Pr SunGod,

I'm 99% positive that all these guys are describing blow off valve flutter, which is common with the more meaty BOVs like TiAL and HKS, and even a misadjusted Greddy .. and not compressor surge.

I'm no where near a "wiseman" so I'll start off with a criptic description and let the smart guys fill in the blank if they choose.

Compressor Surge is when compressor or turbine side (not sure which) of the turbo out does the other with regard to the air flow characteristics....... Dang, that's really bad. I'll stop there.

Anyway, from what I've been told compressor surge will be seen when on the gas and the engine appears to buck in the midst of acceleration(even seen a dyno video that showed this - I think)

Please, someone chime in hear and save my dwindling thought. Thanks.
