Integrated cylinder heads

The big news today is that the Camaro's V6 has been revised for more power and lower weight by integrating the exhaust headers into the heads, eliminating the need for 'a pair of old-school iron manifolds, 12 bolts, a pair of gasket and heat shields with six more bolts.'

When I look at the new heads I don't see weight savings, I see a terrific opportunity to easily add twin turbos to this V6 because the exhaust collector is already built right into the head. How big of a risk is there in mounting a hot turbo directly to an aluminum head?

Honda already does that.

Aluminum is a lot lighter than cast iron.

And, yes, turbo installation is a lot easier.

(what's incredibly hard is heat rejection....)

I suppose the aftermarket header manufacturers aren't too excited about this development.

You can always make a spacer/adaptor for the turbo...

Ahh, but the head porters are looking at the money to be made there.

Before and after power/torque levels? Does it do anything to the power band?

Its just metal! We used to carve up the integrated intakes on our 200 c.i. Ford 6 cylinders to add carbs.

Ross - the new motor makes 11 more HP and highway MPG is up from 29 to 30. http://www.autoblog.com/2011/05/17/heres-why-the-2012-camaro-v6-makes-11-more-horsepower/
