87RON??? It that even petrol? lowest pump fuel here in Au is 91RON
I actually came here from a Google search trying to find a satisfactory answer to the question:
Why do American V8's (V8's sold in the US including ones imported, not US engines sold in other markets) have an exhaust crossover pipe (H-pipe,
The answer I frequently encounter is to do with firing order of the Detroit V8s. Its unsatisfactory because German V8's have a different (more
logical) firing order and they still require a crossover pipe... but ONLY in the US market.
An example would be my car, a Mercedes-Benz 380SE, I live in Australia and this car is the Australian/Swedish version. My car has no exhaust
crossover--US version of the car do have a crossover.
Australian cars that were sold with 351 Cleveland or 350 SBC, also do not require a crossover pipe. Firing order is the same as it is be for the same
engine sold in the US market.
I had yet to find a satisfactory answer on any of the automotive forums I lurk... but lets get back to that in a sec.
Before anyone trolls me with "but does your old car have [insert modern feature]? Yes it does, it is an S-Klasse Mercedes-Benz.

A race car driver (can't remember his name) took a diesel engine, ran the fuel vapor through holes bored in the engine block to heat the fuel
then turbo charged the vapor injection. He also turbo charged the exhaust to increase efficiency. He reported getting extreme mileage numbers close to
200 mph and he also got very high performance.
Smokey Yanuik? I know he developed an engine that would get +400mpg, he showed it to the boards of both Ford and Chev. I thought it was a petrol
engine (SBC?), not a diesel tho, but the principal on how it worked was more like a diesel but using the heat to ignite the fuel and not a spark. Its
definitely worth looking into his story because he was quite close to the Detroit cartels. He spent his later years looking for oil. The only reason I
know of this Nascar driver is because of his engine. Nascar isnt a thing here.

Preheating air fuel mixture is BS too. Ever wondered why the high performance super/turbocharged engines have got air intercoolers? You
actually want the air cold to increase density(more oxygen) and engine efficiency(thermodynamic cycle).
Actually its not, most +1000hp track/drag cars have a fuel pump that also includes a heating element to atomise the fuel. The intercooler you speak of
is to cool the air, not the fuel. When you mix warm fuel with cod air it atomises it and it burns better. You can purchase them from Holley or other

I had always heard the reasoning behind automakers in the US not marketing diesel cars was the perception of the American people that diesel
was a "dirty" fuel. Of course, that is an outdated perception, because of advances in diesel engines and fuel economy. But when most of us think
"diesel" we still think of exhaust-billowing semi trucks and sputtering Mercedes and Volvos.
Diesel has its own conspiracy, it caused a world war... there is a great thread on here about it, may have to search.
So back to my question: Why do US V8's have an exhaust crossover?
I personally believe it is to do with protecting American oil interests, as
well as protecting the Detroit cabal's. If Americans actually drove the same European cars that the rest of the world gets, there would be no Ford,
GM or Chrysler left--they just cant compete with European car manufacturers.
Detroit killed the Aussie Ford Falcon out of sheer jealousy that Australians could build a better Ford than they could.
Apologies for the bump.
