Hello,
Part load is where it takes time and patience. I just settled on an average curve overall after a while. Main thing for me was the utmost reliability I have had since the changeover to megajolt. plus it is very portable from engine to engine too. I have vacuum on the couple and TPS on the KAD.
Surprisingly the KAD is quite the pussycat to drive. A bit heavy on the juice with webers, but then it would be. Pulls away very well at 1000rpm all the way up to 8.5k (although it can go higher). I didnt build it as a GT, but I dont think it would be a problem being one, I would just need to change the noisy drop gears back to helical. Its all a personal opinion though I suppose.
