The idea is to size the hotsize very big to keep drive pressure very low. Low drive pressure makes more HP per psi, so you stress the pistons/rods less with lower peak cylinder pressures.
Ok am i missing something or how does going from running 5 psi to 15psi stress rods and pistons more? Last i checked hp was what killed engines. I understand v8's on the average require less psi based on engine flow capabilities.
so far the turbo suggestion have been coming form the big turbo or it won't work crowd. a stock 350 in no way would ever "need" a t4 footprint turbo when shooting for 350 hp. there so many other turbo to suggest other then a t4 way to big turbo.
for example he could run a hx35/wh1c/hx40 with any number of larger t3 hot sides (18/22 idk the exact sizes), a p trim anything.
to suggest t4 oem app. turbo's would mean huge turbines, unlike the aftermarket where they size the wheels are way larger per housing size. ( ie: p trim t3's)
