Notice the responses about they dont know about automatic in miatas though...see what my wife has done to me guys? I've already got like 60 posts on there, SAVE ME PLEASE!!!

That's just retarded. The blower will peak out before the turbo can really show it's stuff and the motor will be under peak rpm as well. They need to know that even if the charger is dumping the boost, it still has a max rpm limit of about 5600 on a conventional roots system and the larger the cubic displacement of the blower to allow a higher rpm, the higher the power curve comes in so it's a catch 22. That's why Top Fuel cars run 14-71 mag cased high-helix blowers and destroked motors, they both hit at the same time. Why try and get massive low end TQ when a Miata can't even put it down effectively. A Miata doesn't need low end TQ, it has no weight on the rear end. If they want tons of power, stroke the motor and throw a charger on it. If they want high reving power over a wide band, use the turbo. The effective power bands and peak rpms coupled with the intake charge density and temp characteristics negate the possibility of using the setup effectively, at least in a Miata. Say a truck with the room to house all that gear and the need for a ton of low end TQ without the need for a huge rpm redline might be where you could use something like that.
