I mean Jesus fuck, why don't they use these as a base for drag racing? Think of all those revs and airflow.
According to http://members.rennlist.com/pirtle/s4specs.htm
The 5.0 variant weighs 580 lbs which is massive for an aluminum v8. Dressed aluminium big blocks with aluminum blocks weigh similar yet have upwards of 500+ ci. Not to mention that the power in a lot of dohc configs are up high, and a drag race is over in moments. That's why turbos aren't used too frequently in drag classes
Seriously good question. With all these bullshit american pushrod crap V8s being so overdeveloped, masking it's inherent shittiness with displacement, we can finally have a proper DOHC V8 option with all the flow pushfags could only dream of PLUS the displacement! See this is good thinking from OP right here.
>OHVfags on suicide watch
OP here. High end drag engines use shit like billet blocks, forged internals, overhauled cooling and fuel systems etc. to the point where there's little resemblance to the production engine whatsoever.
Wouldn't an engine (such as the 928's) with overhead cams (in an application where weight and space constraints aren't top priority) be preferred to an OHV engine to enable higher airflow and durability at high revs? I know there are people out there getting 11K RPM from pushrods, but they need a lot more maintenance than OHC setups and airflow can't be optimised with 2 valves.
Hence my curiosity towards the Porsche M28's relative absence from motorsport considering its modification capacity.

Few people even know it's an option, but they get full color catalogs to their house weekly about LS engines and it's aftermarket. Which one do you think Joe Jackass is going to go for?
