Hey Dan, I hadn't checked in on this for a couple weeks just been so busy, but I was really pumped to see the progress early this morning. The build is looking great as always, I think everyone here really appreciates your honesty and effort you put into the work you do. Plus letting us see exactly what your plans are and what has been happening is just excellent. So very good work, now for a few questions.
I think the ultimate solution for boost control on a supercharged application would be a servo operated butterly valve placed before the inlet of the supercharger (I bet you could even use the stock SET servo to control it). Restricting the inlet is a much nicer solution than venting the pressure afterwards as you do not waste any power in compressing air & then just dumping it to atmosphere.
I was really curious about this, will this not put extra stress on the rotax, by restricting the airflow in? I'm not sure or saying it's true but it seems logical that more resistance means added stress on driving mechanisms. Perhaps the stress associated with it is negligible.
I'd like your input on this one, as well I'll mention it to my friend who's a physics proff at the university here and can relay what his thoughts are.
Personally, I've always liked the idea of integrating a wastegate system, I know it's tight but if there was room for it that would be awesome. And it's a different story for SC's but for turbos it's an absolute fail safe and critical in controlling boost spikes. Plus for me it's just another beautiful part of the forced induction symphony.
I eventually plan on making a another map (you can remap the A-B-C mode to whatever you want) that utilizes the secondary throttle plates and modified ignition timing on a per gear basis so that I can go WOT and keep the front end just barely hovering off the ground.
I called you earlier this morning too because I'd like to discuss with you the maps and how they might run for me up here in Canada with differences in elevation, octane numbers on our premium pump gas here verses yours down south (91 is the highest here), etc.
And finally, when and how can I send you a deposit on this kit?
Anyways, I hope everything else is going well for you, take care and all the best on the rest of the build.
