I for one am following this! I can't wait to see (via Scotty's videos of course!) that beautiful piece of work in action!
Thanks Dan! And you are right, these heads are beautiful. An absolute work of art to be honest.
But Tom, you're right. I don't think people realize what we have accomplished. Perhaps most people here don't understand the technical side of vintage racing enough for to grasp what has been done to these heads. When Tom and I first started talking almost 2 years ago, my first questions were "How radical can we go? And how radical has been done?" To answer the 2nd question 1st, not that radical. Some good port and valve jobs, but the maximum lift anyone has achieved before was .352 of lift on the Intake. I told Ace I wanted the most radical full out race head. With the help of the new custom high ratio roller rockers, they have the potential of producing
.510 OF LIFT!!! Even with the smallest manufactured twin camshafts, these heads will produce .453,
.100 MORE lift than ever achieved before! And this is compared the BEST winningest bikes in Royal Enfields ENTIRE racing history!
My 700 twin will be putting out the same HP as a Norton 850 Commando... With the small cams and 8:1 pistons. And that is with just bolting these heads on as is and doing nothing else. Once I set the compression and install Interceptor cams, this bike will do 130mph+ without the aid of a supercharger. With the supercharger, the bike should produce somewhere close to 125hp and estimated top speed is very close to 200mph. The only other Enfield ever to break 200mph was Don Sliger with his twin engine Interceptor. And it took him
TWO engines to make 203mph.
I've also decided that because these heads are in fact revolutionary, I am going to test these heads in different stages and set ups so that we can see exactly what parts will produce what numbers with these heads. Every stage of upgrades will then be dyno tested so that all the results are right there on paper. I am going to dyno my bike as is before any other mods. Then I am going to install the heads onto the motor without any other mods and dyno again to see the results of a "bolt on" application, then again after installing higher compression pistons and cams, and then again further down the road after I install the supercharger.
So stay tuned because this is just the beginning of history being made.
Hats off to Tom!
