What are your thoughts on under drive pulley sets? good? bad? worth the cash?

 

good
worth the cash because they pay for themselves in fuel savings

 

Good for:
- Performance (gains from 0rpm to redline!)
- Fuel efficiency (less rotating mass = less fuel used to overcome that rotating mass)
- Wallet -- great bang-for-buck mod, just behind Hondata.

Bad for:
- ??

 

^^ +1 Agreed

 

worth the cost. fuel savings & power gains is a no brainer.

 

unorthodox or nst? cause i want to buy some this month.

 

unorthodox

 

I also went with UR

 

But many have said that underdrive pulleys screw up your engine?

 

I have yet to hear of anyone who claims that with any evidence that doesn't point to the contrary.

 

There have been dynos of the TSX with UR pulley set making 10whp and 10wtq. It's a pretty significant increase. I would stick with UR. Their pulleys are 0 gram balanced and CNC machined.

 

Yea ive herd only good things about UR

 

Here's a somewhat stupid question, but if you replace the pulleys, do you use the same belt?

 

You can with the UR set, but the belt is a tad long. The one for a CR-V is a hair shorter than the stock TSX belt and fits perfectly. I don't know about the others.
