It is amazing to think about the tools that modern racing organizations have at their disposal. We like to think about what the Harry Millers and Duesenbergs of the world would be able to achieve with this stuff just as the masters of today have pushed their equipment to previously unconsidered heights. In this video you are going to see the team at Katech, who you have undoubtedly heard of, run a 427ci version of the modern Lt1 engine on a dyno simulation of the road course at Daytona International Speedway. A few of the things we tried to do were pin down the different parts of the track (especially the time spent on the oval portion of the course where the engine really gets to wind up.

Here’s the thing…these boys aren’t winding the stuff that hard. This engine sees 6,500 RPM tops before hitting the next gear. As something that we’re guessing is built for endurance racing and longevity that makes sense. If you were constantly running the thing to 9,000 and expecting it to live for 24 hours or whatever the interval, it would not make any sense. These babies are tuned to make torque and horsepower and effectively do it until the cows come home.

If you are wondering where they get the programming from to have the dyno “act” like the race track, we are guessing that it comes from the on-board telemetry that the race cars have in them. They can likely download laps from their races and by converting that throttle position information, RPM information, and shifting information make the dyno pretend that it is a road course. If you are wondering why they don’t build a rig to have the engine simulate lateral loads or other stuff in that regard, remember that these are dry sump engines. They don’t give a rip about that stuff.

This is fun and really neat technology at work!

  1. CTX-SLPR

    Didn’t GM build a tilt rig to test the C5 “batwing” oil pans while running around some sort of fake racetrack?

  2. Skeptical

    I feel like this sound should be on a stage and I should paying some fee to experience this.
