I mean Jesus fuck, why don't they use these as a base for drag racing? Think of all those revs and airflow.

Cuz that thing weighs as much as an iron big block.
makes shit power
lol no torque
>>
>>14227254
none of those things are true
or was that the point?
>>
>>14227268
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

>Water cooled Porsche engine

Never Ever.

Because it's a Porsche engine thus very expensive to fix.
>>
Id rather take an ancient SBC and just throw on an aluminium intake and heads

more compact
cheaper
more aftermarket
more reliable
easier to find
>>
>>14227453
I would imagine both of them blown up would make similar numbers.

The Porsche v8 will cost 3-4x that because American V8s have a giant market.
>>
>>14227476
Saying aluminum intake tells me you don't know shit
>>
>>14227509
what

do you prefer a cast iron intake or somehting
>>
>>14227425
so none of it is true? okay

>>14227531
Thank you for proving my point. Stick to forza

>>14226646
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.

pushrodfags weren't stopping you beforehand either

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.
>>
>>14227701
I suppose you need to ask Porsche why they didn't use it for motorsports either.
>>
>>14227710
Probably weight. Porsche doesn't compete in drag racing so such an engine would be impractical for circuit racing when they have lighter flat 6's.

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?
