Intressting for sure.
as my friend Xander drove a euroflattop piston ( raised squizpad and positive deck heigt, wo are) set up at 10:1 compression, and those pistons are now for sale.... why... his headgasket kept on going at 10 PSI he made between ~210 and 240 to the wheels, ( dependable on the real weight of the car, he used road dyno) so APR studs AND a standard headgasket? i doubt it...... however, it did seem to be more responisve.., but 20psi on that combo? maybe on a 8.5:1 and 20 psi? OK given a soup bowl set up would not make the same power at 10 PSI ( Tysons Z made 209 without IC at that level)
But limitations are met sooner, when you need to bite the bullet and go for some pricey mods, aswhere the soup bowls can apparntly handle upto 20PSI on stock headgaskets, making 350 or more to the wheels!
Im in favor of higher compression turbo set ups, as it is the more modern approach.. Our engines where desinged in a time that turbocharging wasnt that common on roadgoin cars...
But how high? and how much PSI you can run?...
Driving with the soupbowls we have gives peace of mind, since allmost everyone here has been there and done that, so we know the limitations of it... so who will pioneer
