Just wondering how you’ve wired you FlexFuel kit. For whatever reason Harrop wired mine straight to the pos battery terminal so it’s powered all the time. I’ve checked with Zeitronix re current requirement and they say it’s minimal and nowhere near in need of high amps. I’m intending to change it to a relay triggered by the power outlet in the glovebox. Only issue I’m aware of triggering it via an ACC powered source is the power for ACC cuts out when cranking so may effect the FlexFuel module.
As for our gearboxs, Neats in Adelaide have a hardening/shotpeening process that strengthens the gears. $2500 for the 86..

Yeah, it’s interesting, a month or so after I had put the alloy one on, I asked my tuner guy if a carbon one might be better. He sort of laughed at me, but had one sitting there, so he was happy to let me trial it. I/he could barely tell the difference.
His experience seemed to be similar to mine in terms of NVH, with both his and his customers cars and his thoughts were that the standard shaft is split and mounted the way it is for a reason.
I’ve certainly been happy with the performance of the alloy shaft, and if all other things are equal the big extra cost of carbon is probably not worth it (at these power levels at least).
As always though, others experiences might be different.
I’ve gone down the weight reduction route, so I run a lightweight crank pulley, and the standard engine mounts seem to isolate ok. My NVH is pretty much all drive train, from clutch to diff.
I don’t know about my flex kit wiring....that was fitted when the bottom end was upgraded. But I think there are some circuits that do stay live during cranking.
The best bang for buck weight saving ( to compensate for the supercharger add) is a lithium battery... pretty much 9kg instantly, and they are much cheaper than they used to be too.
