My experience with Bell Series S1...
Originally, my 1997 Miata was equipped with the Jackson Racing MP45 and 8 psi TDR upgrade pulley. The car felt pretty stout with low end torque, good response, and was about as fast as a stock 99-2003 GT. However, it suffered from noticable belt squeel, heat generation, and poor idle droop. I sold it along with the exhaust system.
Now I have the Bell Engineering Series 1 with GT2860RS turbo, 460 RX-7 Injectors, and Megasquirt PNP. It runs a smooth idle, pulls very hard at 12psi, and has little throttle lag, and can outrun a Camaro SS, but I still miss the throttle response and instant boost of the supercharger. If I had to decide again, I would have went with either Flyin Miata's Eaton MP62 or FFS MP62 coldside, with equivalent engine management or Xede.
Just my opinion, if idle droop and belt squeel were done away with on mine, the supercharger would be considered the best forced induction no doubt...

Full 7-8 psi boost is attained instantaneous with a positive displacement supercharger, I clearly mentioned that heat generation is an offset, especially on the 45 series Eaton. As for parasitical drag, more power was made to offset the difference.
It's just my opinion for the type road conditions that I do, but really the spool up is fast as I need it.
I liked the sound that eaton made, almost like a jet turbine, really kewl...

put a kazoo or one of those whistle/ring things in your IC piping and you'll here the same noise lol......or if you wanna be unique tape a duck caller onto your bov lol ......vroom ....quack!! lol
EDIT: isn't this the wrong section for this post? the begi s1 is a prefabbed kit not a diy and dont we have a section for prefabbed kits?

^ It works too.
Trade Sav for his GT254R turbo...It will spool instantly on the 1.8 and will bolt right up to everything you have...still make more power than the SC setup too. Throttle response + better mid-top end than that setup could ever dream of.
