Adam Cofer of Don Ott Racing Engines talks Sprint cars on Hidden Horsepower

[@sethhughes2163]

Thank you guys once again for another great interview! I met Adam many moons ago, as a few family members are dirt racers. I hear updates once or twice a year and share in " pats on the back " to him for being one of the good young engine builders who support our racing endeavors! To add to the discussion on rings, seal, and piston rock... for the last two months we are running a combo of improvements in those combined areas on a couple of 410's, a 441sbc n/a, and three turbo engines ie: 4000hp+... ALL with a PVD coating we are developing, a new " barrel " boring CNC we built, which actually minimizes " rock " ( clearance is very small ), with one oil... and so far, for instance... the 410... gained 27hp... and 15° cooler on a 9600rpm run. The other engines scaled another 8 to 17% increase also... and we are pushing it as far as possible. We all didn't believe the spintron results 6 months ago... now we all believe... lol. Thank you guys for this platform, as we all enjoy it in the shop and lab! Respectfully, Seth

Great episode, be great to see a little of the Engines, cranks, heads, what ever we get without letting to many secrets out of the bag... plus more of the shop in action...

Don Ott, didn`t he have a machine in San Diego? I seem to remember taking my crankshaft to him in SoCal. circa 1972

Thinking the one thing y’all missing, and maybe most of y’all’s guest’s, don’t realize about themselves, ‘ cept probably Kassse and WJ, is they’ve arrived at a method of thinking, that’s got them recognized, for their innovations. It ain’t all about, “yachts and helicopters”…

I tuned in to see some sprint car engine stuff and seen almost nothing…? Kind of click bait…! 🤷🏻‍♂️😷
