As I often start these threads... "As many of you already know"
98 Ranger, 5.0 swap, OBD2, 5lbs of boost with a roots style supercharger.
After Dyno day I've started doing some additional research on the blower and contacted the vendor finally...
Turns out my blower is a Maggie , and there are smaller pulleys available. It uses some form of M90 case, but it is entirely unique, and made by Magnuson for the X-Charger kit. Wish I knew more, but essentially it is not a 'normal' M90.

So now the next step is "What do I need to do to pulley down"
the vendor's HO Kit for their 4.0 SOHC Mustang blowers is 11lbs, and they had told me that they have only seen heat issues on that kit when it is exceptionally warm outside (90+), and the tune they sell with that kit drops power accordingly for it to keep it safe.
With this in mind, Its the SAME blower that I have, and I see no reason not to go ahead and order the 8lb pulley since stock 5.0's are taking WELL more than that, and the explorer bottom end is beefier than the mustang 5.0's anyways.
So my questions:
What else do I need to upgrade to keep this safe?
I already have bigger injectors, and a high volume fuel pump, that should be more than adequate, but from reading, I suspect my next 'limiting' factor is the MAF as it can only 'see' so much CFM, and when its pulling enough air for 8lbs, it will peg the MAF, which is bad news. Suggestions on OEM/Aftermarket replacements? Any need for a larger MAF, or is it primarily the sensor?
And then finally Spark plugs I'd imagine I should run a step or 2 colder...
I started a thread about the plugs previously, and noone really gave me any good resources... I am going to see about calling a vendor directly to get information on this, but figure it couldn't hurt to ask again if anyone had a good resource for this info.
