Jeez this thread still lives.

Look if all you guys wanna talk about is raw power or speed then the fastest 4 cylinder still isn't listed.

There was a video awhile back of the 4000hp nitro burning 4 cylinder. Should run well into the 4's in the 1/4 at 250+.

Hell there is a shop here locally that builds 4 cylinder motors. Big displacement on 4 cylinder. Think 4.6liter 4 banger
