Yeah he's a little proud of his engine. However he's not too far off on his power. If it is what he says it is, that HCI combo is very similar to mine and it will make around 300 to the tires give or take. Mine made 300rwhp/330rwtq .

That's roughly 350 at the flywheel.

Yeah I think he's being a little too generous on his estimate. I've got an almost identical combo with the exception of a turbo..
 
Maybe he said gt40 crate motor to give credit to the build cause Joe down the street put it together, cause he has unmetered air coming in by way of oil filler cap and Egr is not plugged in, probably runs a tad rough lol

Ya know that's a myth. I hear that all the time. Someone explain to me where air from the crankcase can join with air in the intake passage. Not possible, the intake runners are sealed from the intake to heads. I ran a breather cap on my SSC for 10 years and that ran flawless. If that were the case my car would have vented boost out the filler cap, right? No.

I'm running a very similar settup now but with a water/oil catch can attached to my oil filler cap area.
Still no unmetered air, or boost lost out the vent.

That's Assuming EVERY seal, valve, bolt, gasket, sealent at every point that's a barrier is perfect 100% 24/7 for the life of the engine, ....odds are it's not gonna' last for the life of the motor and the intake gaskets are prone to come loose unless a experienced builder knows the tricks, .....why throw in another possibility fail into the mix to cause erratic idling to rich/lean conditions and chasing an issue???

...and the PVC valve sits on the removable metal web cylinder crankcase sleeve(that can clog from oil and gunk, along with the clogging of Pvc valve) that connects directly to the upper plenum via vaccum hose from that PVC valve. Obviously, SC and power adders can run various vacuum configurations that can be different from stock design.

I know what and where the PCV is. What does that have to do with the before mentioned vented oil fill cap adding unmetered air? That was/is my question.

Oh, and my vert has no PCV
 
@Noobz I think Nik's account got hacked. Someone has made multiple posts from there today.

Crap, I've been caught... Time to go back into hiding...

In theory air could move from the breather cap, down through the oil drainback passages in the heads and block and into the crankcase, then up through the PCV valve... In theory. I don't know that I've ever seen someone do a controlled experiment to see how much air can move through there and what effect it really has on idle/low throttle opening tuning.
