ETP Canted Valve Heads and Billet Intake Here are a few pics of my heads and intake. I have only been to the track once so far and I can say this combo really moves some serious air. Last year at Idle the turbo would spin but slowly and this year it will about suck your hand in! The converter is alot tighter but the boost still comes in well. There are many more pics but they will be in GMHTP soon along with the complete LSX engine build up.
I like the pic of the patriot gold spring next to mine!! The ETP intake and heads are both works of art and have thus far proven to work as good as they look. I also have a set of ETP's new valve covers which did not require ANY rework to clear the massive valvetrain. I have many updates to post about this build and will do so shortly but I want to get this thing a sorted out and running to its ful potential over the next couple weeks.

That is an absolutely killer looking set-up... You should be proud. And I have a few questions, but I understand if you don't want to answer them. <(Proprietary information)
I read somewhere that you spin this thing to 9000 RPM... Is that necessary for a turbo engine of this nature? It's gotta be murder on the valve train and if you are still making power at that RPM, the cam must be huge... My thinking is if they heads flow as much as I know they do, why such a big cam and high RPM? Thanks is in advance for any part of this question that you can answer. And again congrats on your project.

I understand it's a drag car... I also understand it was "designed to rev high" But that doesn't answer the questions that I asked. And I'm not saying it doesn't "work." I'm just asking for the "reason" behind the decision to build it that way... I'm just curious, that's all...

It's simple really. All it breaks down to is RPM = Power. As long as everything can keep up flow and stability wise you'll make more power. More power + hooking it = quicker ETs.

I've been contemplating using a set of these heads on a "similar" project of mine, but I'm going a different route. Not better, just different... The set-up I have in my head is clear... I just want to understand the way they came about their set-up... If they can say without compromising their hard and very successful work.

I guess I am curious who you are and where you are from?? As I am sure you already know there are many factors in considering RPM but I can start with the fact that I am limited to a 29.5" tire and a 3.42 rear gear. With track results and last years lessons learned we were able to calculate the required RPM to meet my ET and MPH goals. From there we began picking the necessary pieces of the puzzel to achieve those goals.
