just looking around on hughes today and looks that they have a new product!!http://www.hughesengines.com/Index/p...r&partid=25542 just wanted to let you all know.. it was under there News & Announcements

 

how does that work with the crank pulley with balancer attached?

 

I just replaced my timing chain/gears today and my crank pully and balancer are all one unit. All the searching I have done shows two seperate units, but not mine.


I wonder how well that underdrive deal works. More power, eh... does anything need to be sacrificed for the extra power?

 

dang, thats the cheapest ive seen....with the alt underdrive, wouldnt it put out more?

 

It drops your Alt-out-put. It's good for about 20 HP.
So at idle, you have to be careful running a big stereo
or extra lights. At speed, with the RPM's up, you'll be fine.

 

doesnt it put a smaller pulley on the alt?......bout how much would it drop? ive got an efan right now

 

it seem to me if the two pullys(alt and crank)were in the same ratio as before, there should be no change in amps.... Bit that just my thought

 

yes its smaller but it changes the output somehow. It spins faster so less power output or something. I have seen a lot of people on Mustang forums say they had charging issues with underdrives. Then again some had no problems at all. Its pretty much a hit or miss deal with them

 

2pc steel u/d on a 5.9, probably see about 5rwhp gain. Added March 3pc alum u/d pulleys spring 98 and saw .12 seconds off 1/4m ets which I estimated was a 6-7rwhp gain.

Smaller dia means it spins the alt faster, hence greater charge. Without smaller diam pulley the battery would be dead in a matter of days at most.
No hit & miss with u/d pulleys. Everyone that runs them has charging issues, some just dont admit it lol.

 

I never had a problem on my stang and I have all kinda power stealers
