Interesting article; thanks for the link.
I wonder if that dyno run ever got done (?)

Great article! I saved it in mht format here in case it ever goes down. Just unzip it, then open in Firefox (with mht archive plugin) or your favorite browser. All the stuff should show up perfectly.

Great article! Thanks for posting! Still never ceases to amaze me how dumb some people are that leave comments on those article.

Here's a video of a dyno run; audio but no data.

Thanks Mike; well that audio sounds killer or at least the engine does.

That video is from Thunder V12. com. Wildly hopped up V12 that can accomplish 5,000 rpm and make turbo big block chevys look like junk. lol Put it this way, the dyno could hold a big block down below a certain rpm, but this beast outdid the dyno because of the beast amount of torque !
