This morning we finished off Ziggy's F8 with Boondocker and a hermaphrodite (part stock part custom stamped looks like it won't fit the stock heat shield) BM single prototype that matched Ziggy's F8 modded stock pipe. The modded stock pipe had that camel hump dip just...

Wednesday before Shootout
We struggled again today with Boss Noss, added a restrictor to help cut down 45 psi fuel pressure. Made extra 25 HP on our first pull today .72 LB/HPHR BSFC, but gas solenoid began leaking fuel into the engine. Got my magnifying glass out, gas solenoid is good for low...
this dyno session ZR800 Boss Noss
The sled on the dyno right now is an essentially stock ZR900 EFI with speedwerx slightly high compression head and SLP twin pipe, bondocker box, and Boss Noss nitrous oxide injection system. We tweaked for a few hours today, fuel flow was way too high even with fuel...
Shootout certification update–
Jimmy Cooper was contacted today by Bombardier, explaining that wrong ECU's had been shipped to DynoTech. No one called me. I will guess that last year they fooled me with the same dragrace ECU. Look at the numbers on DTR last year's Shootout. That one had way too...
