So at the risk of inviting competition, here are the 1000cc pushrod records at Bonneville (and El Mirage):
Bonneville:
P-PP buell 144
M-PG guzzi 158 (no aero, amazing number really)
M-PF h-d 150
A-PG guzzi 151
A-PF h-d 167 (someone in the F class actually running fuel?)
MPS-PG guzzi 170
MPS-PF buell 181 (ditto on the fuel)
APS-PG guzzi 171
APS-PF guzzi 170 (obviously the gas bike with mods to pass fuel tech)
El Mirage:
P-PP unknown 138
M-PG guzzi 142 (my record)
M-PF unset 137 (minimum, maybe I'll go after this next year)
A-PG unknown 154
A-PF unknown 169
MPS-PG unset 144 (minimum, I'm going for this next week)
MPS-PF unset 151 (minimum)
APS-PG guzzi 161
APS-PF unknown 165
My 1000cc motor is an old road race motor, not a drag race motor. The only way I could possibly think about trying to match the M-PG speed (158) from Bonneville would be with a new 90+ HP motor (~$10K). YM(PH)MV...
This sport is a lot harder than I thought it would be. Consistency is the key. I have had a total of 9 runs to date (I'm a rookie this year), and I have only had one run close to my best (backed up the 142 with a 141). Otherwise I can drop as low as 131 or run 136 if I pick the wrong jetting or gearing, but sometimes I have no reason for why I'm slow (or fast for that matter). Run Bonneville if you want the mystique (and corrosion), but El Mirage offers more opportunities to run per year, and on vehicles with low records, the shorter length is not a hindrance.
In case you haven't been paying attention, El Mirage added over 300 M classes last winter, and set (what I believe to be) low minimums. I decided to run last winter before I had heard about the new classes, and figured I'd have to run A. Once they announced the M classes, but hadn't yet published minimums, I figured the minimum for M-PG at ElMo would be about 150 (looking at the other 1000 pushrod classes at ElMo and Bonne). As it is they set it to 130, I went 129 my rookie weekend, 136 the next, and 142 the next. I appear to have stalled there, and so I'm adding some aero for next weekend and will go after the MPS-PG record. Come out, have fun, just stay behind me... 8^))
