Got any driver openings? 
Just a thought….but why not go with a dual exhaust straight out the back? It occurs to me, and I'm not a mechanic or a racer car driver. In your exhaust setup at the rear with the bends going back to center, you could shave another 3 lbs. in exhaust tube weight alone. I'm sure you need to 'marry' the pipes to balance it out but could you do that with an "X-tube" type setup closer to the headers or a "bleed" tube of lessor weight and diameter?
Also, would like to see your intake system…IF you happen to have one of those pics.
Were you the only Box represented in the field? Didn't see any other 'side' intakes.
Keep up the good work…and keep us posted! :dance: |
Thanks! On the exhaust stuff, yes we do like to merge the two sides together. With the suspension subframe and longer 6 speed transmission case, there isn't much room to do any merging further forward in the car. We can't run any pipes underneath because of the low ground clearance either. The pipes I have now are a little longer than absolutely necessary, but that is because we wanted to be able to insert the largest mufflers possible in that straight section in the back leading up to the merge. Every once in awhile we run tracks that have a maximum decibel reading, and the option of adding mufflers there was a goal.
I think there is a few pictures of the intake set-up earlier in the thread. Basically some 3" aluminum pipe running from the throttle body into the rear trunk by the coolant tank. The right side air scoop on the side of the car has been modified to feed air through the right rear quarter panel and into the trunk. A larger cone filter, some sensors, hoses and hose clamps...nothing particularly fancy.
I was the only Boxster that far up front. There was one other 3.4L conversion Boxster there that weekend but it was a few seconds back. There is a Cayman in my class that has some side intakes too but we ran pretty good gap on that car as well.
