TiAL is what my buddy uses on his Skidoo Turbo....600+ horse on a sled, and he had an EVO IX with over 900 HP....in his 20s and knows the hell out of Turbos...so I recognized that name when you said it.
So stupid question...if you switch out the BPV for the TiAL BOV are we suffering from Turbo Lag by NOT having the intake Air recirculated through the intake vs. venting to Atmosphere?
Thats awesome!! I have an evo too, not quite as much horsepower haha but Its a road race car. We specialize in turbo kits at our shop so we have a lot of trial and error, learned a lot over the years.
So cars recirculate the bov for two reasons, to quiet down the sound ( most people for want their factory cars to make that much noise ) or if the car has a MAF sensor to read air. Most of the time the car meters the air going into the motor before the turbo, so if any air goes missing before it gets to the engine the computer freaks out ( eg. you dump it into the atmosphere ) so to avoid that, they dump it back into the intake before the turbo but after the MAF. The ecoboost motor doesn't meter air like that so its easy to convert to a VTA BOV. It really doesn't make any difference where the air goes as far as turbo lag goes however you can really minimize lag between shifts and throttle input by having the bov as close to the throttle plate as possible.
Also we love Tial because it is American made.... 'Merica
