The cylinder head work was done by a real artist that has been working on high end stuff for decades. The exhaust side ceramic was ported with a diamond burr and the intake ports were welded to add material and change the port shape. “Real” porting is a lot more than just grinding away, in fact enlarging the intake ports with a die grinder will usually make things worse – there is an art and science to it!
The valves are a little larger than stock (the head shop does not like to give out specific specs because the total package is more than the parts – people will just copy the valve size and expect the same results.
Put it this way – I built Alain’s engine and after looking at the head work I decided to put away my porting tools, I will either use a cleaned up stock head or recommend this guys work. It ain’t cheap but it is the way to go if you want some serious improvements.

When you get a chance, could you pm me the guys name and contact info. That's something that I really want to invest in.
Thanks,

Whatever became of this car? I find it incredible that it had just under 450whp at 16psi. Wonder if they modified it further?

~450 rwhp for a 2.7l 8v at 16 psi at ~6100 rpm is a bad joke and not possible. But that's not the only sketchy high hp dyno sheet we've seen from that dyno..

The project is slow moving, but should completed finally this year
Having been one of the lucky people to have personally driven the car at points along its way I can say

I'm sure the car is fast, no doubt about it.
But 443 rwhp means 503 crank hp when using 12% transmission losses.
Now, 503 hp at 16 psi means the engine is producing around 240 crank hp in N/A form.
So... 240 hp from an engine that produces 163 hp stock.
So could a high flowing head, a different cam, a better header but 2.9 points lower compression result in a 50% increase of VE?
No, not very likely.

Guess you missed the cfm numbers that were temporarily posted from the improved head that originally was apart of making those numbers

Having been one of the lucky people to have personally driven the car at points along its way I can say Yeah, but things really start to move when you reach PLAID.

P.S. Higher at the crank in N/A form
I wonder if it was the inspiration for the Turbo S
