What is the downside to underdrive pulleys? Will the battery go dead easier? Will the airconditioner not work as well, will the water pump not cool the engine fast enough?

Thanks for the info

 

Anybody with this mod have any problems?

 

No problems

 

I've had the UD pulleys on for about 6-7 months and had no problems at all. I doubt anyone will have any problems either. Maybe years back it would have been more risky.

 

the down side is 189 dollers for them!

 

try 249...

 

wow went up! :notnice:

 

You can get them for 169 on Sean Hylands site

 

This is good info. I have been thinking about headers and pulleys.

 

Working fine here.......no noticeable temp rise.....Of course we have 9 months of winter , 1 Fall , 1 spring and one HOT

 

no problems here!!!!!

 

Check out SeanHylandMotorsports and read what they say about their pulleys. Some companies are selling a 3 pulley underdrive kit which can damage the alternator. Also, the weight needs to be close to the factory pulley weight. I see a lot of kits that are lighter, a lot lighter, which also can cause a problem.

 

ya i ordered those...then after 2 and a half months of no pullies and no contact with me they refunded my $$$ and i bought steedas from someone here with it
