Can a Rocket III take down the establishment, and rule this island

If these guys are “seasoned” drag racers used to hitting a tree and you are not it’s going to be an up hill battle. You will need to hit the tree so practice , practice , practice . Remember , if you don’t go red sometimes you’re not trying .
Most important thing is to know when to get off the throttle and race another day.

trust your bike, don't beat yourself, practice is the key

Small update here, I've been back on the mapping and worked my way up to 80% throttle and near 8K rpm with very little pinging and AFRs are OKish.
Did a test pull the other night, got some beautiful cone-shaped jet flames out the exhausts from 7-8000rpm.
Also went from 50-90mph in 2.2 sec (which is about the same as my gen 1 Hayabusa already rolling in at 100% throttle).
This is rolling on with moderate aggression - i.e. taking 2.3 seconds to roll on from 20% throttle to 80%.
It was faster from 70-90 than it was 50-70mph,.
The knock detection is set to max sensitivity, and picked up an amber alert around 60 and pulled some timing to slow engine down too. Felt like the clutch or wheel was slipping.
Reckon it is putting down near 200 wheel by 7k at 80% throttle.

I still got another 20% throttle to go, and another 1000rpm, plus I've the ignition pulled well back to start safe and work my way in.

Soonest the dyno could fit me in is September 14th, so I'll probably be finished the map myself by then lol.

Sounds good, keep moving forward. Dyno would give you peace of mind and reassurance, plus you'd get to see the numbers climb.

Wow! I can’t wait to see the dyno numbers on that beast. My TQ starts to drop off at 51/2-6K will yours be spooled up and going higher?

I think 5.5-6k is where torque peaks on the Carpenter engines, but this has been stroked and supercharged so that might change that a little.
Time will tell I guess

How much boost are you throwing at it ?
It sounds like it is a true beast . Just watch the AF cause as you know you can run rich all day but lean only once .

As much as the charger will make... Haven't maxed out yet so don't know. Was hitting 22psi absolute at 80% throttle and 8000rpm so about 8psi boost so far.
There's some T2 impeller upgrade available for these so might go there next but will see how it goes as is.

Ive the ignition pulled back a bit for safety, and fuelling generously so as i work up through the map it's starting on the rich side and i make adjustment to lean it a bit. Rather than the other way round.

I iron out the AFR first and then start adding timing back in.
