The header was a combination of thoughts from a few friends who are making big power and specs from what we know works. its a big boy.

The car is making great power with a stock im and 1.6 cams but I wouldnt advise just anyone to go 92x92, its not as easy as bolting on known parts and go. You will be disappointed When you make less than a smaller motor.


I'm sorry to disagree. I respect and admire your build greatly. I do think that design would cause mass amounts of restriction and turbulence in the plenum. I would like to see the results of this testing, something like a flow bench or even better maybe some kind of fluid dynamics testing in a tank where we can visibly see the the active flow around the plenum chamber and into the velocity stacks themselves.

I guarantee this would be robbing airflow and hp as well. With all that excess metal from the velocity stacks I'd bet your total plenum capacity has dropped close to half. Your plenum for optimal design should be as close to your motor as possible, so for you 2.4 liters of total volume.

This manifold has already been flowed on my old head. Flowing 90% on that particular head gave me enough indication that it is more than enough for the new head that flows 40cfm less @ 0.5in lift. The mid/low lift on the old head was also greater. At the end of the day I am sticking with this design as going itb is not where I want to go right now. If the stock IM flows enough for 260hp on N1's with this motor, I should have no problem.

For shits and giggles I will bolt a stock IM on the old head and slap it on the flow bench to compare. I also have cory's coming soon.

out of curiosity what flow bench do you have?
also if you wouldn't mind would you be able to chuck up a picture of your bore adapter? I've just started building a flow bench at the moment and would like to see how people have made there adapters.

I'd like to know what comparisons you have from stock to non. Not tryin to bust your balls at all. Just want to know .

Its a Superflow 600.

Let me get Kenny to take some pictures and get the ok to post them. I already got in trouble for postings pics inside the machine shop.
