While trying to make the jigs to drill my heads for twin plugs I ran into a
major problem. Where is the plug going to be located on the bottom of the head. I made up this jig to located where the plug will be located. Angle jig Test jig installed Installed Bottom view |

We've been at 100Hp/ liter for quite some time, but only up to 2300ccs or so... As the big engines get bigger the ability to achieve the efficiency to make the mark gets more difficult with a two valve head and pushrods, NA
The engine in this video is only 2.3 liters, based on a Type 1 and made this power with the fan belt and cooling system in place, here on my chassis dyno. It is a STREET CAR that competes in unlimited street, meaning it has to make 25-50 mile cruises, then take it to the track. http://www.youtube.com/watch?v=EgwnJsCaHtw Ten days later another engine that I designed put down 5 HP more than this one, also 2.3 liters.. Having two 500RWHP beasts on the dyno back to back is an accomplishment for me. Twin plugs have great possibilities and we are still finding the perfect chambers, cams and dynamic compression ratios that boost their effectiveness... Its ground where few have gone before, so there are no rules, no questions that can be asked and no reference materials to follow. If their was I probably wouldn't be wanting to do it. None of it is cheap and it never will be... Its also not super profitable for us and never will be. There are cheaper ways to go that offer compromises. If I want something more modern, I just jump in my 996 and I reserve the vintage iron for what belongs in it and make that bastard haul ass.
