Question Shorter Crank Pulley

Anyone here had any exp. with putting a new crank pulley on their Impreza? It's a rather inexpensive idea we've been toying with and I've heard it could take 2 or 3 seconds off my quarter mile time. I've also heard it's relatively easy to do.
I was just wondering if anyone had any feedback.

The underdrive pulley helps a small bit. Is it worth it? Well, there are some other <$200 mods that should be considered first, but yeah, I'm happy with mine.

I have no idea if the UDP shows .3s improvement in a quarter mile. If that were true you could remove your AC belt altogether and really help!

Thanks for the feedback.
I really don't race the car, so I am not interested in shifter kits and sway bars. I just wanted to find out what anyone thought of it just for making the car quicker.
Someone w/ pulley experience enlightned me to the 2-3 second time increase.

Hello,

The 2-3 seconds hogwash is the only thing that Dale at Teagues has claimed that makes no sense whatsoever. I think his car had a rat or mouse or something stuck in the exhaust when he did his baseline testing. Everything else about him is cool and he's a great person to work with. It's just his silly 2-3 second gain with the pulley...

Cool

Guys, I may need feedback, but I ain't THAT new to this I had an intake over a thousand miles ago. It was my 2nd mod.
Dale at Teague's wasn't my source. It was another race tuner.
I apologize that I didn't notice someone post this in the newbie section, guess I didn't consider myself a newbie

Sorry, didnt know what you had. Bottom line is there is some minor improvement. Is it worth $200? well.... I dont doubt the 4-5 hp gain. sounds about right. Think there are other things you can do with that $200, like save for cams.

Summit Racing claims "up to 37hp" Does that fall under false advertising? Where do they get these numbers? Add up all of the claimed hp gains you have....

Well, I have the pulley. Its noticable, but if you're looking for power, I think the intake is a bigger gain. Besides you get the cool sound too!

Summit's prolly basing the results from high powered turbo cars which can benefit alot from racing pulleys.

It's more a combinations of mods that get you the most power. Most everybody that is serious about wanting more power out of their EJ25s end up replacing the pulley.

Right legacyGT. If you want NA power, you are eventually going to replace the pulley. Every little bit ads up. Just some are more cost effective than others. :
