The engine: 1397, Ward head, +1mm intakes, JE 13?;1 pistons, Web .445" / .415" lift cams, Marine lightened crank, stock rods. It should have hauled ass.
Bonneville results: Running 1650-M-AG. I freakn suck. I made 15 runs, with the best runs at 192mph... actually slower than previous events, and I chased my tail all week. And yea I mapped and edited every run, and changed gearing about twice a day.
Please don't think I'm complaining, I'm not. Running on this years salt was epic, hanging with my friends Greg, Kim, and Jim, of Black Art Racing, drinking at Carmon's Black and White... This is what I live for, it makes my soul smile like nothing else.
Anyhow...
I have finally made progress to diagnose and resolve my lack of HP while running at Bonneville a month ago. Fireman Jim and I performed a leak down and compression test and immediately tore the bike down. The dry compression was 160 on all 4, and then with a squirt of oil, compression jumped to 210 on all 4. The leak down was loud and clear through the case, pointing to rings. All the valves were good, with no contact damage what so ever. As expected my ring gap was .005" oversize on the top, and .003" on the 2nd ring.
My cam settings were higher than I had set them, we found 113 / 113 however they were checked at .030" rather than .050" that I used to set them, so wtf.
Something that surprised me was ALL the intake cams lost ~.004" clearance in about 70 miles while running WFO at Bonneville. All the intake valves and seats were bran spankn new... I know the gas I was using (ERC A19C) was incorrect, my dynamic compression was low, the octane was to high (117 I found out later), and I installed a set of fugged up injectors by mistake. So yea.
The corrections we are making are:
1= Reseting cams to 108 / 108 as per Ward. However, piston to valve clearance will determine timing.
2= Purchased a beautiful new set of Wossner 14.25:1 pistons to bump my dynamic compression. The JE's were as flat as a 7th grade skinny chick. The Wossner's on the other hand are perkey as hell.
3= Ring gap will be reset to .004" per inch of bore on the tops, and >.004" on the 2nd's.
4= Clean injectors...
Gonna put her back together, and get ready to run the Shift Sector, Coalinga 1/2 mile drags.
Smokey Burnout!
