This is a D16A1 DOHC D series engine being mated to a Garrett T28 pushing 15-20 psi of boost. What do you guys think?

Thanks.

what does an O ringed head mean?

Is a T28 even efficient at 20psi?

Sonny

At 20 psi, the compressor is still in the 70% oval of the compressor map for the amount of airflow I need (I'm guessing conseratively at 29 lbs/min).

I may not have to push it that high to get the power I want (~230 whp), but we'll see.

CustomCockpits: An o-ringed setup is when they cut a little groove into the deck and put copper or steel o-rings in it that stick up above the surface of the deck. When the head is torqued down, the compression on the o-ring creates a stronger seal.
