I dropped a tenth by getting rid of the clutch fan, but still using the belt driven water pump. This was when I was running high 11s.
Dropped another tenth w/ an electric water pump when I was running mid 10s.
I've always run w/ an alternator. CHIP

That's pretty impressive, actually.

Every time I toss a belt ( pump & alt - no fan as it is electric ) I gain .13.

I ditched a clutch fan for an electric with shroud. I saw no firm gains, maybe a couple hundredths at most. Still running the stock water pump though, I'd switch over if i knew the car was gonna pick up, but I'm not so certain.

How much improvement are you guys seeing with a electric water pump and electric fans ? HP or ET's 
Thanks inadvance !!   
I have tested removing the water pump belt(no alternator, tight water pump belt only) on two different 440 motors on two different engine dynos, 8 HP gain on both 
That's more like what I expected.

The 2 tenths I shaved off was also while using an alt.

Years ago with my ld car I dialed in at 10.49, water pump belt blew off at the launch and I went 10.29! I was exstatic driving back to my pit til I saw steam under the hood, now I'm in a habit of watching all my gauges.
Even with an alternator I was running 2 tenths quicker after the changeover, and easier to cool between rounds.

Along with 2 mph gain.

Yes, it is .10 improvement on my car if I turn the alternator off. I have a switch to open the field circuit.
Yeah, it's got a smallblock.

anybody ever tested to see how much ET an alternator will cost you?
It seems to depend on the alt (amps?) I knew that I could depend on .09 by takin off the belt, even made it into a mini quick 16 race once by doing that, but after that alt died the one that replaced it must not have been robbing as much HP as it was only good for .03 off the ET. I'm guessing the one that died was a higher amp alt?

we took the belt off of Woody's car last night and it made hardly any difference

Yes... That is a GOOD Question also !! I plan on running a powermaster 140 amp or a 120 denso for my ragtop. how much HP would this big 140 amp alt. take away VS a 60 amp? IS it putting more of a strain on the engine than a 60 amp? Bigger 140 amp robbing more HP that a 60 amp???? just wondering !
