Aluminum heads $ per HP?

okay I will speak so I'm not misunderstood. With a pro comp closed chamber aluminum head both the design and product material both combat against detonation allowing you to run more timing with a smaller combustion chamber providing more compression or and power

I know what you mean. It's just looking at it from the taillights.lol
A smaller compact chamber, plug in the right spot, will burn faster shorter flame travel. That means youll need less timing..add quench and its helpful re mix effect will speed that too with a more complete burn.Also with the faster burn...one would think there is lesser time for end gas or hotspots to light up an opposing flame front.. as well as dead spots from fuel fall out etc. The cooler faster dissipation of heat through the chambers counters the hotspot issue. Really.. more heat causes greater molecule expansion ..and they expand so much before heat induced self ignition. It gets much deeper and goes into all sorts of pitfalls of traditional chamber designs of the 60s
But it mostly revolves around pump gas, or maximization of its resistance. Run everything at 99% its capacity/tolerance and you'll make thee absolute most power, right .
When you look at a piston or a chamber and you see dark areas vs clean spotless areas...that's showing you where good mix is and burning vs fuel fall out/lean...however tight quench area show lean/clean too. There are some really good circle track articles and engine builder online I highly recommend people search and read, read, and read some more.
Really the smaller compact chamber design lends the bigger hand though.
