I don't speculate, first off about products I work with facts, as far as Weapon-R goes I said they have made a similar product (read more carefully) and that the cost was less which is a fact, also I never stated it was a Versa Manifold..
Many people did show intrest when you first posted about your product, but there was never any response from you other then what you said in your post on 7/30/08 found here

Also I have done group buy's before, so if you want to do a group buy you should at the least set up a link with your shops web address were members could sign up for the group buy(pre-order), it would help you and members come to a median.
Now since you have a manifold that has been made and dyno tested why not sell it as an "as is model" to a member, like Fox Racing did with the Turbo Versa Parts when it was done. Let members see your serious with this product, and that it can do what you say it can for the Versa in the real world. It could be your sponsored car.
It shouldn't hurt you production wise to sell it, since it is already made and you do have the spec. plans so what do you have to lose.
Pictures in magazines and words will only go so far people need solid proof.
