hey guys i was wondering whats the pros and cons of daily driving with a new under pulley from rrm?? my friend said theres going to be tons of underdrive

 

Pro: Feels like a brand new car in the lower rpm range

 

There are no cons. I've been DD with mine for over 60,000 miles.

I've had it before turbo, after turbo... I never really experienced any cons. About the only thing is your lights dim a little at idle, otherwise there are no driving issues.

Plus it sounds cool when you're rattling off your mods, "Yeah, I've got, xxx, xxx, under drive pully, xxx..."

 

Pulley is a great mod, you would be far pressed to find any negatives to owning it as its a really great helper mod.

Same here.

 

Cons--
When taking your car to the shop under warranty, it's an excuse for them to use to void your warranty..
For $150.. the performance gain is mostly psychological, but some say they can feel it.. I surely didn't get wood after installation. I'm not *****ing, but it does look cool!
Pros--
Read the thread above.

 

no, the performance is not in your head, it was dyno proven by joe's_evo8 before RRM even thought of selling it. Joe worked out something with RRM and they took over production of Joe's design. 5-7WHP and 9TQ - dyno tested

 

Drewbad drives an auto, so the difference wouldn't be anywhere near as obvious for him.

 

Pros - cheap, easy DIY, + everything else everybody says!!!

Cons - ???

 

good point.

the difference at the crank is the same, your increase ATW should be the same percentage when compared to ours, but less actual HP and TQ changes ATW due to the torque converter issue

 

you lose your harmonic dampening pulley and switch to a solid pulley. negligible, but it is one of the cons

 

and that's a bummer man, I didn't realize you drove an auto. you must have munchkins to carry
