Boosted 346 w/ AFR 225's cracks 800 RWHP!

I think the impressive part is that it's making ~800 rwhp on 15-16 psi on a D1SC with stock cubes and you need good flowing parts to make that happen. Us turbo guys have it easier to make more power more efficiently IMO.

I agree w/ Tony M, (sorry MM) but I believe better flowing heads provide greater efficiency at cramming air into a motor. If you boost 20psi to make 800whp....and I boost 14, to make 800whp (on an apples to apples combo except for heads)......which turbo is creating more heat? Then set them both at 20psi.....which makes more power?
I'm not doubting you MM, I admire you in fact lol
I even used a video of you running 10s rowin gears in a presentation back in my college days!

How about the fact the .750 deck thickness in the AFR can handle alot more cylinder pressure before it starts lifting head gaskets. Its literally twice as thick as a stock casting.
Another perk of the efficient head (and superior aftermarket casting)....alot of people switch to our product for that very reason.
Can't deny the fact that more boost is certainly the great equalizer....an aspect of performance an N/A application doesnt have the luxury of relying on.

PS....The answer to ninetres riddle is whichever combo makes the most torque (and has the highest BMEP numbers)

Explain limited.....I'm confused. Several folks have gone deep into the single digits on "stock limited blocks" lol. Maybe you were being sarcastic

Sorry, I meant stock bottom end, lol.
Meaning that on the stock bottom end your limited to mid 5 to low 600 rwhp to be running safe and have the least chance to blow the motor (pending a good tune).
So people dont usually start lifting heads until 18 or so psi or more correct? Well theres not a turbo out there that you can run 18 lbs on without it being super innefficent and make high 5xxrwhp.
most people run 8 lbs on stock bottom end, maybe a bit more if they are confident in the tune/gas. Thats my point.

This gives me great hope for my build. I was thinking I would have a hard time obtaining 640 rwhp with a 383 stroker kit mated with a 90mm single turbo at about 18-19psi. Very encouraging numbers for staying with stock cubes!!
