So ya the new one will flow more air but i found a 50mm at a good price and want to get it buy a lot of ppl say to just get the Q. If everyone was running them b4 the Q came out they had to have been good right... my question is shud i just get the 50mm and not worry about the added flow that much or does the Q make a world of difference??? FYI i wanna eventually get to 500+ whp so lmk if the added air flow wud be a significant benefit over the 50mm.... pls help me im stuck!!

Through countless hours of R&D we were able to make the same size valve flow a staggering 60% more than the original design - that means 60% more air is blown off per cycle! This is the highest flowing BOV on the market.

I'm rockin the old school one with no issues though.

 

If you're getting the older version at a really good deal then go with that. If there's not a huge difference in price I would pay the extra $$ and go with the Q.

 

im rocking the 50mm with no issues ever, 40+ lbs of boost
