Ok, I'll be upfront that I'm just being a bit of a Devil's Advocate here. I like the MAFT and from what I hear, I'll probably end up owning one. I've plowed through most of the DSMtalk threads on it too. But, just to cause trouble I'll ask the following from those of you that have it.
Anyone have any concrete dyno numbers or even track numbers and actual gains from this mod? Before and after improvements? I know the 3.5 in flows like the Mississipi in and of itself but when you neck down to the throttle body is all that flow lost and even disturbed by all the steps to get it to mate up? The 2G MAS looks to be pretty close to a 3" MAS flowing more or less straight through. Although tuneable, can it match the increments of the SAFC in terms of fine tuning? Granted, everyone who's bought one seems to love it. I'm just wondering if anyone's truly dialed it in on the Dyno and done a side by side with the 'old' SAFC 2G mas combo. OK, flame suit is on. Time to endure the punishment of the translators. ![]() -------------------- |

Well, all I can tell you is my butt tells me it makes my car faster.
![]() In draw-through the turbo is sucking through the resistance of the MAS, but its pretty clear to see that the GM MAS's, with their higher flow rates and aerodynamic design, offer less restriction than either of the stock DSM MAS's. As far as flow goes on the car, we basically measure that by the turbo. For instance a small 16g flows 505 cfm at 15 psi. It flows more than this at a higher boost pressure. Obviously the 3" GM MAS can easily handle this much flow without overrunning. We can run a turbo that flows up to 800 cfm without overrunning the 3" MAS. After that, its probably best to get a 3.5" MAS. |
