This mat have been the best Shootout ever–decent temp, lots of snow,
13 aftermarket sleds. And we caught one ringer. all results will be in
SnowWeek magazine. After that article is out I will post my numbers of
stock sleds including that wicked SkiDoo provided Mach Z ECU. I’m still
kicking myself for having Jimmy Cooper overwrite the race fuel map with
an 06 fuel map. We should have reinstalled the stock retarded ECU, let
it run that way at the Shootout and I could have sold that
Shootout 10 HP extra hotbox on Ebay for $1000. I need to pay Jimmy
Cooper for the five hours he spent here with his Doo computer getting
this ECU correct, and Ebay would have made that easy. But I still
have the 600SDI race box, we didn’t mess with that, renstalled the
original ECU in the sled. That may show up on Ebay next week so we can
remunerate Cooper’s Sales and Service (585-682-9707).
Curt came back today with a full N2O cylinder (please don’t call it
noss) and we finalized that evaluation. The newly supplied EFI Boss
Noss box was fitted, now needle valve fuel flow was seemingly in range,
we were able to dyno tune Curt’s ZR800 into the twilight zone. Actual
dyno results will be released after Curt lines up with his dad’s RX1
Bender turbo stage 1 (Curt’s dad has no idea what Curt is plotting).
We finished with Curt’s juiced up ZR800 this afternoon, and we hooked
up Mike Ziggy Zigmont (we found each other on the I90 today) to the
SuperFlow dyno. Mike has a Bikeman F8 and ran blubbery but safe all
last year with 58 psi fuel pressure. Now we have installed a DynoTech
programmed Boondocker and we’ve been able to drop fuel pressure to 45
psi. In an hour we created a safe .700+ BSFC and 11/1 A/F ratio from
valve opening to HP peak and beyond. Those Boondockers are great EFI
tuning devices especially if you can tune on a fully instrumented dyno
to utilize.
Sunday we will finish off Ziggy’s F8, will try the Bikeman F7 mod stock
pipe, then spend the last part of the session tuning midrange, part
throttle settings, to make sure we have no lean spots. ziggy’s F8 will
be powerful and reliable after we dial the Boondocer in tomorrow AM.
Somtime tomorrow Erich Long aka Bikeman is supposed to show up at DTR
to dyno his two Shootout sleds. I’m hoping Sunday 10 AM we’ll be done
with Ziggy’s Boonocker/ various single pipe tuneup (3 hours total) and
we can next wrench and tune Erich’s two F9s, albeit after the SW DTR
Shootout. I love my job.
