Trusting honest people who are trustworthy is a valuable commodity in this world... it's the invisible glue that holds the business world together.

Greed holds business together...greed and booze.

There's nothing wrong with self interest where both parties financially benefit from freely choosing to enter into a business transaction.

Wealth is created.

In contrast to self interest is greed where one person's gain can only come from another's loss.

Wealth is transferred.

I like this project. I have one of these intakes laying around...if this works out in terms of gains mark me down for a flange.

You got it, malibu.

Documented gains is the catch in all of this.

I'm guessing the design should yield good torque numbers because of the length of the runners, and how they are directly in line with the axis of the throttle body. However the stock manifold runners, although much smaller in diameter, are also very long because they wrap almost all the way around the plenum. I really should have taken a picture of the underside and back of the manifold before leaving it at the machine shop so that you'd be able to see what's going on there for yourself. The stock manifold looks like a snail underneath.

However, I really like this particular design because it gets right around the whole plenum issue of trying to draw in air at a 90 degree angle to the flow from the throttle body.

It's highly possible that the manifold doesn't produce any gains at all. After the engine is completely broken in I think I'm going to need to do a dyno run with my car to get a baseline and then do one with the manifold to get a direct apples to apples comparison. This could all end up being just a useless piece of engine bling!

...

...but finding out is what life is all about.
