unorthodox racing, underdrive pulley kit?
I see in the parts section this new pulley kit by unorthodox racing, and it says a possible 20 to 40 hp gain..my question is, if this is true, how much hp gain really?? and what are the downsides if any?

Rep Power: 419 It won't give you that much. I think a 5hp gain is the maximum. Quicker revs too. The downside is if you run a lot of electrical accessories, then you need a bigger alternator because these pullies also lower alternator output by 10%.

Rep Power: 0 Companies always post the Highest gains their product has produced. Which is most likely not for your vehicle. Some Exhaust systems free up well over 30HP..On Highly modified turbo-charged engines when comparing the to stock.. but they never advertise the fine print. Some Intakes can give you 20HP... (On Model X only) Like an intake for my old 1974 Coronet.. Turned it from a 160HP engine to a 184HP engine.. But at a loss of torque.. then I swapped engines for a blown 426 Hemi Police spec engine (had a cracked block that was re-welded and resleeved)
