Ever since I first turboed my car, I have had fluttering / compressor surge every time I left off the throttle. Partial throttle, WOT, doesn't matter. I am looking to try and mitigate that now. I have been running a knock off tial wastegate. A friend offered to let me bolt up his Greddy to see if it resolves my problems. However, the flange for my BOV is on my most complex i/c pipe. I'd really like to try and avoid remaking it, or turning it in to a mess of welded sections.

Has anyone ever seen an adapter to run a greddy BOV on a Tial flange? I am finding lots of adapters to do the opposite, but nothing to go from Tial to Greddy.

 

you could put a straight section in a different location in your ic pipes with a greddy flange if that works easier and just leave the tial bov in place.


if it does, get a real Tial and set it up properly.
