Looking for R+D testers for Defined Auto promo headers
Looking for R+D testers for Defined Auto promo headers
We originally had 10 spots open for this deal, now there is 7 left. Everyone will be considered for the program. Just post on this thread or send me a PM if you are interested. 12a, 13b 6-port, 13b 4-port, 13b full P-port, Bridge port, ALL types will be considered to join in R+D development.
The deal- Testers will purchase a Defined Autoworks prototype header that is built specifically for their engine setup and car. Cost will be a very discounted price. If no extra power is found vs. the existing header, tester can return for a full refund!
All headers carry a 1 year warranty.
What we need- Car must be using some type of programable ecu. so that the user has control over Air fuel, and timing. OR a carburetor and distributer that can be tuned. The tester agrees to visit a dyno before and after new header install. The tester also must have knowledge of how to tune the vehicle, or has access to a tuner. Once the results are found, the user agrees to publish the results on forums.
Pricing will vary from $480-580 depending on the application. Regular price is $750-800 so this is a heavy discount. We MAY also give a "sponsorship deal" if our decals are applied to the car, and the vehicle participates in some form of racing.

Sounds like one of those commercials that offers "free trial" for the first xxx people that call.
Seriously thou, that's a lot of money for just a header even at the discount. Are they ceramic coated?

The design is holding the current highest document n/a street port 13b, street port 20b, and semi p-port 20b. We would not offer a full money back guarantee if I thought each one wouldn't produce more power than any other header on the market. This a two year old dyno chart of our 13b first gen street port.

They are not ceramic coated, we use 321 grade stainless steel which is MUCH more expensive. Everyone uses 304 or lower. 321 is designed for ultra high heat, and retains it better than other forms of stainless. Our header is fully TIG welded, and uses more material than the average bear.
Its not being a guinea pig if the product has already been proven. This is not a new idea that we have, these headers have been developed for over 3 years

don't take me wrong it's just the OS was assuming everyone was familiar with the product. Now you are giving bits of info for people to make a semi-educated decision with

Not criticizing, just asking:
1) These look heavy; what's the weight on the 12A header?
2) What's the wall thickness on the tubing?
These other questions on second glance seem to only refer to the 3-rotor, but IMWK:
3) Considering the shape with the extra curves, can they still be installed without having to pull (or demount and lift-in-place) the engine?
4) Looks like you absorb a lot of your extra length by going back and forth under the transmission. How much more heat are you transferring to the trans?
5) How much ground clearance (if any) is lost?

2) Wall thickness is .060" or 1/16th
3) You are looking more at the 3 rotor headers, which have alot of bends. Both however can be installed and re-installed without moving the engine
4) This is also only a 3 rotor thing. To allow room for a large third muffler under the chassis. A three rotor is so much louder, I designed this in mind.
5) No ground clearance is lost on the 3 rotor header, and its the only one that travels under the transmission. The 2 rotor does not bend this way. Its simple with one bend at the engine.

I will send you a PM for sure
Here are some pics of our hand built collector that is on each of our headers sold. This version is for a 12a, 13b is similar just slightly larger throat diameter. I think this helps convey the differences of our collectors vs. any other header available.
