I'm more concerned about ~30 psi? I know GNs make some massive power, but do they run boost that high? I'm thinking no. Any insight as to how strong these are at about 30 psi boost in blow through mode will be appreciated.
I think the blow through setup opens up a lot of doors for people like myself that want to switch to a "real" BOV like tial, but without VPC can't drive the thing everyday when there is no way to vent it back in. To be able to put the sensor right at the TB, and vent a large BOV with no ill side effects, is exciting stuff.
Another thought about the GM mas size... in blow through mode you could get away with a maf in the same diameter as the upper piping, or in my case 2.5". The air is compressed, and the mas will look just like your IC pipe to the incoming air. Having a 3" would make up for the small amount of area lost to the sensor parts inside the pipe. But going any larger probably wont help. In fact going from small to big to small is the major reason why we DONT want to gasket match the exhaust mani, etc. Conversely, when using one before the turbo, you want it to be the same size as the turbo inlet. For most turbos, thats no problem. But when getting up to 4" inlets a 3" mas will become a restriction again, though not nearly as bad as a stock mas. But then again how many people are running stock mas (especially 1g) with a turbo large enough to require 4" inlet.
I think for poeple in this group, blow through is the way to go, and this opens up a much cheaper route to tossing the stock mas...I am axiously awaiting a report on how well this works in blow through. If anyone does it, please, for the love of God, post the results with as much info as possible
. Unless you want to 2 foot all your stops and try to consume extra boost he's off his friggin rocker. Where does all that extra boost go when you get on the brakes after a hard run? Nowhere, your compressor will start to surge and just pump heat into the piping full of deadlocked air. The exhaust manifold is still friggin hot, the Turbo is still spinning at 100,000 + RPMs, regaurdless of how you drive. I had a Turbo 280Z which was a cool Turbo car, no BOV. I don't claim it to be a good idea, it was a primative car that needed to get with the times. There is a reason for a BOV, it serves a purpose regaurdless how you drive, it protects against surge and keeps the Turbos RPMs UP. Sorry to get off subject guys.
