Octane Alley Manifold?

[routier1642]

Does anyone know anything about this manifold?
Looks like a competitor to the CPR6.
They're claiming 25-30 rwhp, although on the same page, 20-25 rwhp.
Interesting that it looks a lot like the standard manifold.

A post here says it's a ported LY7 manifold.

Anyone have any experience?

Don't know about the manifold but they are claiming hp not rwhp. rwhp will be about 25% less.

Yes, my bad. Thanks.

And about 25% less again for kW.
So 20-30 hp becomes 15-23 rwhp, which becomes about 11-17 rwkw.

Still, has anyone used one?
I like the idea because it would be the same height as the factory manifold, which means it would fit under my strut brace when I have my 12mm insulator fitted.
On the other hand, it doesn't seem like a big improvement for $1300.

I know, I know, synergy...

Cpr6 are now $1350 so same price anyway.

That's good news. For some. Not me. :-(
For performance, I'd rather have a CPR6, but it won't fit now that my 12mm insulator is in.

Unless I removed/replaced the strut brace, bulged the bonnet, etc. Too many $$$

UPDATE:

I finally spoke to the guy at Octane Alley who developed the manifold.
He basically said that the manifold was a standard Alloytec manifold that it's really for racing.
The manifold has been completely re-worked on the inside to improve the flow, but that you wouldn't get much benefit unless you got a new cam package, and a specialised MOTEC ECU replacement and tune that would disable your normal dash computer functions.
So not much good for a street car. :-(

Yeh not really much bang for buck.
CPR6 is likely better for Street App but is still bloody steeply priced.
I have the same problem. 12mm insulator and a strut bace. Already clunks on the manifold grooves as is.
But damn I'd love a CPR6.
Maybe if they came down to the triple digit mark... one day...
