Evolution of my 996 Turbo
Mike,the heads on the two cars are the same,intake is different......I believe John's GT2 still has the stock maf location.The cams are different spec also.
How many of your guys remember Wilbur?

As i said earlier the only similarity is the placement of the maf,everything else is different.The filters are not in the wheel wells as with Proto or Switzer.
I don't think we are following
When using a blow through MAF setup, there are not too many ways to route the charge plumbing. In order to get the decklid to close and everything to fit properly, this is about all anyone can do to get it all to fit. The shape of the pipes, etc. are caused by the size constraints. We have looked at, and are in the process of designing a less restrictive draw through MAF setup which we may use. If we go this route, the charge plumbing will still look as shown in the photos Joe posted.

Now we are talking brother. I was waiting to see what the heck you were up to big dog. First you will get rid of that dip around 6500rpm that GT3 motors have in common, then this will give a more linear graph which will then give a more area under the curve which means more power as you know. My goal was to reduce RPM range but have a better curve, great job and nice port/polish work. Who did the work? Turbos choice is also the best now with that motor, guess you did your homework well on that too. Y-pipe and push through MAF looks great too. Just wish me luck b/c the Lambo just came back from Heffner with more power, a lot more, no a sh...it load more. Good work bro, things are looking good. Hey you are still the master of the Mile

Actually, the design was introduced by Protomotive with Wilbur's back in 2001.

Joe - that's a great looking set-up, very nicely done. I never liked the filters in the wheel well and thought of doing something just like this at one point. Did you go this route because you wanted to hear the blow off valves or was there a performance reason?

Evoms decided to go this route mostly for performance reasons considering the hp level we are looking to achieve and the use intended for the car.
