Jay Brown just did a complete buildup of a 511 FE motor on the FE forum. Big motor,high compression,.700" lift cam, 1150 carb, major head work and list is there with charts. I know of 2 484 FE motors with the same major work, One runs 58mm Berg carbs, the heads done by Kuntz the other is wtcobra's motor. These motors make 700 hp and spin to 7800 rpm. I would like for someone at a dyno to show me how a motor with 10.0 compression with a cam under .650" lift is maken 700 hp. I have run the numbers repeatedly and 80 hp and 100 ft of tork are missing from both Dyno 2000 and Dynosim. When I built my motor and it was dynoed, the hp was 5hp off and 8 ft of tork. Webbers or Bergs will make 20-40 hp more more than a carb in the mid range but loose in the top end to a carb. Webers or bergs have the ring housing inside the throat of the carb bodys, The TWM don't. Depending on injector spray pattern would add maybe 5-10 hp. Jay is in the Engine master challenge with this motor, the REAL numbers will come out in the writeup. If anyone is build a 500+ motor, go to FE forum and read 511" FE at the Dyno. right now it is on page 2 at the bottom. There is some great info there. Yeah I know,I should live in the Showme State.
