can someone tell me what HEMI stands for????

 

[-Fred-]

Hemispheric. this name was due to the shape the valves had, or something like that.

 

[Gil]

What he said. It had to do with shape of the combustion chamber. Mopar has been building Hemi engines for many years.
The most Famous was the 426Hemi.

Mmmm....Hemi. God I love those engines.

Yeah, what Gil said. The Charger in Fast and Furious was a 426 cubic inch Hemi, and would probably make about 900-1100 horsepower supercharged like that and burning 94 octane pump gas - no nitrous.

A race-built, 500+ cubic inch version of the same engine, burning nitro methane, will make about 5500 horsepower.

I got yer Skyline right here, pal... :smilewink

It has a hemi-spherical combustion chamber. It has a higher compression ratio and doesn't use as much fuel and provides quite a significant amount of extra hp/fuel consumption boost. Honda D Seies engines have a Semi-Hemi i.e. 1984-95 Civic's and CRX's.

I don't know all the details, just basically relaying the info that other people have told me.

"HEMI" is not an acronym. It's short for hemispherical.

I onced owned a Plymouth Grand Fury with one of those engines in 440 cubic inch trim. (70s Ex-police car). My first car. Almost lost my license with it, too.
