One of the businesses I work is automotive based, I do HEI, MSD trigger only and EFI-HEI conversions to point distributors. I get to go to a lot of perfectly useless dyno comedies, and see stuff like in the video all the time. Just goes to show that when the wrong diameter primary pipe is used in a header, power gets better when a too big tube is altered smaller. Old racer's saying, " you can't trade volume over velocity". Too Big, is too slow in stuff like this. One better way would be to use a tapered primary pipe in the header, just as our two strokes like. |
