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

22psi is significant. Have you boost referenced IGN timing adjustment?

 

[R-III-R Turbo]

Well that's 22psi absolute so only 8psi boost. Ive not referenced boost for fuel or ignition, figured it's supercharged so a bit more linear than a turbo say. Just going with setting the tables myself to suit.
Using a POD 300 to log pulls and video camera too on the gauges for good measure.
The Autotune does a little bit of work and the Vampire system pulls ignition if I start getting pinging, lights up the gauge and I can feel the engine back down. Feels like clutch slipping almost.

I misunderstand, you have 8lb boost. That would be much easier to manage.

Slight update here, have hit 100% throttle at times, and went as far as 8500rpm albeit at 80% throttle.
Getting zero pinging on the knock gauge - which is turned up to max sensitivity, so anything at all sets it off...

So I reckon once I get the fuelling alright at this point, I can start advancing on the ignition until I start getting some light pinging - and stop it there.
Interestingly, the revs climb quicker as the boost & cams come on;
(in 2nd)
4-5000rpm takes 0.92 sec (rolling on 40-70% throttle)
5-6000rpm takes 0.92 sec (still rolling on, 70-80% throttle)
6-7000rpm takes 0.81 sec (holding ~80%)
7-8000rpm takes 0.48 sec (holding ~80%)
8-9000rpm.. not measured yet..

Dyno date set for 14th September...

All l can say is wow !
Impressive numbers. If you can get that beast to hook it will be some ride. Can’t wait to see the dyno numbers

Me too, this build has been some years in the making, so it's a "moment of truth".

I just found out there is a 'T2' impeller available for the Rotrex C30-94 supercharger, which gives a few more psi and flow, 20-40hp kind of thing but unfortunately there isn't time for that before dyno day.
I'll have to get that done in the winter and might need a retune.

Hows your clutch pack steels and fibers you think? You’re spinning it up now, tire, steel’s definitely been slipping

Yeah there have been times where I'm sure the clutch or wheel been spinning as the acceleration from say 50-70mph is fast but then it's noticeably faster from 70-90 kind of thing.
It's like it gets traction and goes better.
Haven't had to take anything apart since the new pistons etc last August so no idea what clutch etc looks like I'm afraid.
Just been tearing around having fun for a few k miles.
Planning on replacing clutch and inspecting a few bits before drag races next year though.
