As of now my max horsepower NA engine===1398 at 10,300 rpm
My best with NOx----they didn't have dynoes that could check it at the time
My best Supercharged engine---they not only didn't have dynoes that could check it but it exceeded all the max theory performance levels thought to be possible at the time

At work I operated vehicles with more than one engine and there levels were known but classified

but if there is going to be a race, I need a little time to put one back together
