The Syncronic valve is 2.18" longer than an SSQV included the dual M4 port nipples on the rear(Atm dump). If it’s run in recirc mode, add 1.15" to that length for the recir tube adapter.
I like Tial alot. I also like the S.Engineering stuff too. I’ve used both quite a bit but I tend to use the Syncronic more. The SE parts are more visually appealing to me, that’s really what it comes down to as both companies are equal in terms of performance and quality.
Plus I’ve used a Syncronic diverter valve as both a bypass valve and as a “wastegate” to control boost…simultaneously and 100% effectively. Can’t do that with Tial…Even threw Peter for a loop with that one(owner of S.E.)
Jim FWIW…Peter does make an adaptor flange for SSQV fitment too so if you go with the syncronic later on it’ll be a bolt in fitment.
