201.1HP/Liter NC35
FINALLY!!!!! After years of developing parts, and breaking parts, and developing more parts, and breaking more parts, we have finally broken what has seemed like a barrier for power for the little NCs. Our previous best power was 88.6hp. Not quite 90hp. That 90hp target has eluded us for various stupid reasons for so many years due to this or that problem. I think we have always had the capability to make the power, but never had the chance to prove it on the dyno - until last weekend.
We reassembled the 450 and finally got to test all of the basic pieces of the puzzle that we have been using in various engine configurations. This was just the first opportunity we had to put them all on one engine at one time. And, we didn't put it all on (more on that later). The graph below illustrates an ALL STOCK NC35 (blue) at 56.4hp in showroom condition vs our original best power recorded back in 2005 of 88.6hp and then last weekends run of 91.3hp.


Take a look at the torque difference between the ALL STOCK bike and the 450 (Dark Blue vs Dark Red lines). The 450 practically idles with more torqe than the stock bike puts out at peak (OK, that was an exaggeratin, but close)
As I said, my original target was 90.0hp. That works out to 198.2hp/Liter. But, with the 91.3hp run, that also broke the 200hp/Liter barrier coming in at 201.1hp/Liter. I am pretty excited, but tat the same time I feel we should have been able to record these figures years ago - if it hadn't been for all our set-backs. But, we did it now, and we're ready to move forward.
The engines shown above havd completely stock valves (including springs and retainers), stock cams with only adjustable timing, the heads have been slightly ported (Seriously a 20 minute clean-up job) and the valve seats cut by hand to a nicer racing 3-angle job. The heads are not milled as to compression comes in the pistons. The only real mods are the Cosworth Pistons, Carrillo Ti Rods and Billet Crankshaft and the Alternator Conversion Kit. The rest of the engine is OEM Honda including the carbs. They are the F-III Kit carbs, but basicall NC-30 carbs with super-short stacks and no airbox.
Next of the agenda for testing will be Big-Valve heads, FCR Carbs, Cams, Ignitech Ignition, Exhaust System and Electric Water Pump. After that.....we will pull out the Fuel Injection. This is all hopefully going to happen from August through December of 2010, with final results by the end of the year. Cross your fingers for us. That 100hp mark is getting closer, but yet is so far away.
Cheers.

+1! That is very good stuff and data, Mike. Keep up the good work as pioneer.

Yes, I forgot to add HRC Ignition to my list (still OEM Honda though). We have a couple of Ignitec Ignition Boxes from Rick Oliver that we are testing with, but haven't had the time to dail them in yet. Soon. I am hoping very soon.
My current rider (the owner of the engine graphed here) Mark Elrod was setting to out win every 450 Superbike race from beginning to end of season, but he fell 2 races ago and cracked some ribs. He tried to race the last race on July 11th, but the Gods were against him from the beginning. First the bike wouldn't start the night before the race. Then it quit during Sunday practice so he had to park it. That was later attributed to a broken Pulsar Coil wire on the main harness from the first Ignitec testing where we had an occiliscope hooked to that lead. I guess the puncture through the insulator weakend the wire enough that the crash did the rest in

But just to show the Gods weren't done with him, he borrowed a bike to run for points, only to have that bike lose battery voltage in the 2nd lap. That was the end of that race for him. When he finally got back to the pits, he discovered the bike was running a Total-Loss battery set-up (ie: No Charging System) and the owner didn't know to tell him. So, that was a frustarting attempt of a weekend to just gather points. Now, because of a silly Ignition wire and a battery (I always did hate the electrical side of things), he's out of the Championship lead by 28 points

Just to add to Mark's weekend, the Gods decided they weren't going to let up on the frustration just yet. A friend of a friend of Mark's Wife came up and said, "Hey Mark, you're wife's been trying to get a hold of you. She's just gone into labor and is on her way to the hospital - 3 weeks early"!!!! So, Mark (with still healing ribs) had to load everything up and hi-tail it back to the San Francisco area (about 3+ hour drive) and get right to the hospital. He made it before the baby was born. So,as a reward for his good sportsmanship and great conduct, Mark and Tawnya Elrod were rewarded with a new baby racer, Aiden Conner Elrod the eve of one of the more frustrating race days that Mark has had.
So, all because of an Ignition box, Mark is a daddy

Re: 201.1HP/Liter NC35
Awesome! So, where do I get one?
This has me excited, because now you should have time to rapid prototype me those yokes you have been promising me for 2 years!

Re: 201.1HP/Liter NC35
To hell with the HP. I like the Torque number.
Well done.
We are starting in on version 3 of mine. Hope to make 72 on his Factory Pro dyno...should put us about 82 on a Dynojet.
