would a new pulley be a good upgrade for a 2.4 or no? (i am thinking most answers will be "no" but i am just curious)

 

itll allow you to rev quicker...i heard its quite a noticble upgrade.....were talkin lightweight pulleys, not underdrive pulley

 

lightweight good, underdrive bad

 

Flywheel will give 500% better performance but is harder to install and will last less time..

Either one will more than likely void any engine warranty you might still have.s

 

i been thinking of getting the light weight crank pulley but its not a high priority for me right now

 

The returns are not worth the cost.

 

why would you say that the underdrive pulley is not good. do you have one on your car right now and can say it is worth less. does anyone make a light weight flywheel for our cars yet

 

Yeah there is one I have heard of. I believe it fits our car.

Pulley $200 + dollars... Reduce Rotating Mass by 1 Lb...

 

jaslowyota got one he told me he felt a really good difference

 

i have one on my maxima and i noticed a huge diff. ill prob get one. does anybody know if there is a light flywheel for our trannly

 

my friend knows where we can get one for the 4t45e auto tranny he also knows where to get a racing torque converter I'll ask him from where and I'll get back with yall

 

Sorry but that's a bit scewed. Before you tell people that something is bad, try and explain why you say it is.

Most people think underdriven pulleys because they hear urban myths of it taking away lots of power and messing up your charging system...is this true? Partially.

Yes, an underdriven pulley is smaller than the stock size, which will reduce the amount of power going to accessories (example: head lights, a/c etc) but it's a very small amount of charging difference. How do I know? I have one and have had one for over a year with no problems what so ever. The headlight dimming issue, a little bit noticeable but that's only at idle...when you're driving and getting the alternator going, charging isn't a problem at all.

But let me clarify, I'm not trying to flame on you Brandon, just trying to educate a little I guess.

 

ASS DYNO?

 

An underdrive pulley wont even fit on our cars. and i will post the dyno sheets when i get back into town. To make an long story short it made 4djhp.

 

The after market pulley only weighs 1.8 pounds so i dont know where your getting your numbers from

 

Your cool man. I wasn't 100% sure of the reason (although you explaining confirmed i what i though) so i didn't want to try and exlpain it, just was tossing my opinion out there. Next time i'll clarify.
