Freeing up horsepower

Hey guys, most of you probably already know this, but switching to an electric fan from a belt driven fan makes a significant difference in horsepower. I just tested my jeep this weekend with the new fan installed and the difference was noticeable. Just wanted to share my excitement with all of you.

I got close to 40 HP out of the R Type sticker and 29 inch rims I installed last weekend as well.

How about some pics of the install and a parts list. How difficult was it? I'm looking at changing to electric becuase I'm tired of replacing fan clutches.

I want to see before and after dyno resullts.

If your fan clutch is working properly there is very little drag on the engine when it is disengaged.

Ahhh my dear Watson... let me inform you that I did not even bother using Flex-a-lite's crappy thermostat. I used an 88C (off) 95C (on) bimetallic switch screwed onto a Tee that I installed on the radiator hose. I did not have any overheating problems with REALLY hard wheeling but the outside temp was around 22-23C. Now I just have to wait until summer when it can get close to 40C. If I have a cooling problem I'll just replace the switch for something which will open at a lower temperature.

No, I wasn't being comical. I'm being perfectly honest. I don't have any dyno tests. But you can FEEL the difference, especially on a jeep with 33's, 4.11s and a crapload of steel. I had no idea that I'd get such a noticeable difference!

That is indeed some insurmountable evidence you have brought to the table. I have no choice but to admit defeat.
