My buddy has it done, he says he got 4hp at the wheels from the mod. If you live somewhere that is hot year round I would replace it with an electric fan. Visit understeer.com for full info.

I thought about doing that mod.. it's not worth it with this southern california weather. One day it will be nice and overcast.. the next scorching hot! Too bad...

1 mod you can do if you are in a warmer climate is to remove the warmers off your intake and throttle body. This will allow much more colder air flow into your engine. I have done it and my engine and cooling system love me now
