i dont know about the whole "ultimate turbo performance" but i guess it would look good if you wanted to be different?

i'd rather go topmount personally.

I have an early development manifold at home from them...

The nice thing about them is that they are machined and have nice smooth runner and a straight path to the turbo...

Big cast piece of shit.
Nope it's actually a 2 pieces of BILLET STEEL with MACHINED RUNNERS that are WELDED Together.

You're going to have a hard time finding ANY manifold that has such smooth and straight runners... I got my prototype on ebay... 80$... I don't use it, my setup's done... I just bought it to study the design, and maybe modify it for a future twin scroll setup.

My versions weighs 20lbs and looks a LOT heavier than the production version which probably wights about the same as a cast manifold. A standard cast turbo manifold weighed 17, and an SSAC weighed around 12... We compared them when we did MikeD16z6's new turbo setup.

Compared with a tubular or cast manifold, here's my assesment:
Pro's:
- Precision machined runners and collector make for minimal bends, and maximum velocity to minimize lag.
- No tubing misalignment issues
- No casting imperfections
- very sturdy and very little risk of cracking.

Cons:
- Cost - I bet it's over 400$
- VS. a tubular manifold, this is NOT Equal length so it will flow less at high RPM's. (UNLESS they did a flow analysis and modified the runner diameters to equalize the exhaust pulses which would help reduce the flow issues that they inherently face with a non EL design...)


A lot of you guys make assumptions and jump on bandwagons just by looking at pictures with no actual knowledge... :TD:
Props to those that can think outside the box and come out with truly innovative ideas.

^true^ A log is not even in the same ballpark as this.

This manifold has runners that smoothly merge into the collector. Log manifolds dont have this.

First impressions... Whoa! Totally, odd, different; but like was stated above, a good design.

Seconds impressions... Don't think I'd run it though; and especially if it's near what gpny said. Nope!
