Im exploring this option for my next build. I took a look at the kit available at ka24der.com and it looks awesome. Fig. 995$ for kit and around 500$ for a used m62 sounds really cheap and easy bolt on. Im undecided on fuel management (walbro,8:1 fmu with a BTM?) and I guess ill go ahead and get a wideband for this one since its kinda uncharted waters. I know most superchager kit set ups come with fmu to make their kits "bolt on". Maybe get a underdrive crank pulley just to get going.
Im a little behind on superchargers reading that they dont "compress air. They more or less "cram in the air? Also id imagine they flow a way higher cfm at low boost lvls. than say a t25 turbo set up.< Maybe a fmu is not a good idea in that id need like a 12:1 ratio?
The numbers the few out there throw down are very promising! 220-250hp! 22-250tq!
I also think i could very easily fab up the plate adapter and make this happen for next to nothing.
