/\/\ I do not understand how you can say that "Eatons are incredibly inefficient blowers"
I don't want to argue, but a stock 99 cobra with stock pullied eaton makes 420RWHP+ and 380RWTQ+ with only O/R X and catback..
So what's a better set up for 3 grand that you guys talking about???

It's no problem, and I don't want to start an argument either.
The reason I don't like Eatons is because when you pulley them it is easy yo push them beyond the efficiency range, A stock eaton with a stock pulley runs at around 60% adiabatic efficiency (which isn't too good for a supercharger). The rest of the energy is lost in heat.
As a comparison paxton novi's run at around 80% (I know it's not really a fair comparison because the novi is a centri blower.)
And when you pulley it you will see more power, but the effincey of the supercharger drops even more as it will produce more heat and put more strain on the blower.

I'm not one of those a-hole who's try's to argue over stupid things either. God those people annoy me. Thanks for not being one of them. Life's too short.

I really think the centrifugal superchargers suit the 99-01 cobras better because they are high revving, also with a centrifugal supercharger if you drive it conservatively and keep the revs down the supercharger isn't putting any more strain on the engine than driving n/a, but it'll still haul when he opens the taps.
That's what I'd do if If i had a 99-01 Cobra and I wanted to go faster.

I would do: novi, Vortech, Procharger (my preference), KB, Whipple... among others over the Eaton... Just some are more $$ then others, lol
The issue with the Eaton is really the heat... it heats up VERY fast... ask any Terminator owner... we all know about it.
