So this is my understanding for cobra owners as far as pulleys are concerned. We shouldn't change our alternator pulley because the lights already dim a bit stock, and water pulley is smaller then the GT one so that should be left alone, so this leaves me to belive the only pully worth underdriving is the crankshaft pulley?

even though the cobra pulleys are "underdriven" from the factory they are still nowhere near REAL aftermarket underdrive pulleys. Aftermarket ones weigh less. That is the main point. Less rotational mass=more power. Same principle for driveshafts. I put a set of MAC pulleys on my 94' cobra (all 3 of them). Replacing the alternator pulley was a bitch because the nut was in there pretty good. Anyway the only thing i get is the gauge cluster dims a little bit at idle when im waiting at traffic lights with my lights on. When you just touch the throttle for a little bit of gas, the lights come back on to full power. When i say the lights dim, i don't mean they go almost completely off; i mean its such a small difference people looking at your car wouldn't even notice it unless they were really reallly looking. Thats my experience anyway. I say if you're gonna do underdrive pulleys, do them all. Not worth the effort replacing just the crank pulley for an extra 4hp or so.

if om not mistaken, the stock water pump pulley on the cobra overdrives it compared to the gt. and underdrive pulley is larger than the stock piece.

so from ur responses they still seem to be just as worthwhile investment as they would be on a gt, are there specific pully kits exclusively for the cobra? does ASP offer one?

You are correct sir, the cobra h2o pump pully is the only one that's different then the gt's. And yes it's overdriven not underdriven.

is it necessary to keep it tho, isn't it overdriven because it also works in par with the factory oil cooler ? or is it fine to change also

No other cobra owner here has had issue changing them out. The oil cooler is like a tranny cooler they work of them selves. The only thing you may notice is the car will run a little hotter but nothing to worry about.
