Our plan from the start was to dial-in the big wedge with a trip to the Westech chassis dyno to sort ... both the intake and exhaust, and then went into some higher rpm test runs.

So with that idea, we called up Doug Schoenfeld at Schoenfeld Headers to develop a plan using Circle Track's dyno mule as a test bed ... (one engine dyno and one chassis dyno) and more NASCAR ...

I once described its staccato exhaust note as sounding like a thunder ... was enough to convince me to take both cars to a chassis dyno to find out how much of a difference there really is.
