New 20b NA Headers by Defined Autoworks
 

Logan Defined Autoworks has made a new set of headers for me. These are an advance on his last 20b NA headers and is an example of the headers he is now building for testing and sale. These new headers were developed based on extensive testing and iterative redesign, but these are a newer design. We are going to do some testing on the dyno next week and will be able to show just how much power they add over a very good set of equal length headers I had on the car. I can't wait for the next few weeks dyno testing of both the new headers and the new intake plenum and runners. Logan Carswell and David Barninger (KD Rotary) will do the testing and we're thinking of videoing the sessions.

The headers are part of a significant upgrade of my entire exhaust system (as well as the air and fuel intake system). In addition to the headers, Dave Barninger is building a 3-way exhaust system that adds pipes as revs increase, and a new through bumper dual exhaust that is in my projects thread in the 3rd gen section.

Old Headers
Here are a few pictures of my old headers, which were very nicely done.

New Headers
Its hard to figure out which to show first. I didn't have a lot of build pictures, so I think I will just show the headers off by themselves as completed. They have not yet been ceramic coated.

So, the headers are finished and on there way to KD Rotary to be fitted and tested along with the new plenum I designed. We are going to dyno my base car as it is and then swap the headers and dyno again. Then, the old headers and new plenum and then the new headers and new plenum and runners together. We should learn a lot. Logan Carswell (Defined) anmd Dave Barninger (KD Rotary) will be doing the testing on Saturday the 19th. Anybpdy in the area who wants to come by, PM me. We'll have beer and sodas and coffee and snacks.

Beer! I'll be there! In my Jeep though, took the FC off the rd today :(

TitaniumTT... Great. Looking forward to meeting you. Where do you live, btw? I think this is going to be very interesting and show what can be achieved with better, more scientifically designed intake and exhaust systems with NA motors.

:rofl: Gordon.... we've m et before, we went over this the last time I was I Dave's and we spoke on the phone ;)

Live in CT, it's generally about a 2.5hr drive for me.

Yes... but, I have Althzheimer's... ;)

djmtsu... and that's why I call them "menage a trois"... ;)

WHOA. SEX. I could gaze upon their glory for an eternity...*snaps-back-to-reality* are they goin' on PP 20B?! HOPE! *crossing-fingers!!

Project86... Thanks. I am looking forward to seeing how the headers and new intake work.

fbRXse7en... Exactly. Erotic art.

Gordon
