Before I begin, I dont want this to turn into a debate about using BOVs etc. I am well aware of all the advantages/disadvantages of recirculation, vent to atmosphere and no BOVs so I would appreciate it if we just stuck to the info I am looking for
I have a pair of older HKS SSQVs (or whatever they were called then). HKS sells the recirculation fittings for the valves in 3 different sizes, the largest being 29mm OD fitting, for a 29 mm ID recirculation hose.
The inner diameter of the Y-Pipe for the two recirculation lines on the Y-side for the BNR32 is ~35mm ID and ~38 OD.
So the questions are:
1. Has anyone recirculated the HKS BOVs through the stock Y-Pipe?
2.If so, how did you do it? (i.e. Pipe sizing etc.)
I know I can make it work by using a smaller OD piping as a gasket for the HKS fitting, but wanted to know if anyone had done it a cleaner way.
