When we did the dyno test on Bills car, the only difference other than the headers was the oxygen sensor was unplugged as there was no bung on the new headers.

And ST, just to clarify, these are "stepped" headers (1 5/8" to 1 3/4").

The initial development was done back to back with ER's and showed we had at least a 10HP gain on a 9.8:1 Euro SC. I agree we need to do another back to back test with the production units and that will be soon. I will post the results when I get them.

Thanks!
Jim

Btw, Another customer of mine just dyno'd his 1987 3.2 "E" class club racer with 1 5/8" ER's and it made 208 at the rear wheels.
