Lightweight pulleys...?

Just a random thought passed through my skull, and I decided to come here for some Tacoma-specific answers.

Are there any benefits to adding lightweight pulleys to a stock engine, or is it one of those mods strictly for our forced induction friends?

 

My friend put a set of lightweight pulleys in his honda accord. There was a much better response in the throttle. I can only assume it would do the same for a Tacoma.

 

Yeah...Lightweight pulleys improve the parasitic drag on the engine.

Less rotating mass means they spin easier and that extra power from the engine is free to move your ass!!

 

Horsepowerrrrrrrr

 

Well that's good to hear. I've got a hell of an ass that needs moving!

 

You said it...I just like every extra little bit I can eeek out!! Got other things to do first tho. Tire/Rims, Air locker, OBA, recovery gear. THEN the engine to compensate for everything I think.

 

you are not going to get much of anything with light weight pulleys...if you want to get something extra go for under-drive pulleys.

 

What are the major differences between lightweight pulleys and underdrive pulleys?

 

I thought he was referring to underdrive pulleys when he said lightweight pulleys. What IS the difference?

 

A lightweigt pulley is just that...one lighter than stock...reduces rotational mass and gives back a "little" and I mean...very little power.

Underdrive pulleys rotate your accessories....alternator...power steering...water pump slower..using less parasitic power...can usually gain a few possibly 10+ HP this way but.....less current....possilbe overheating issues...I would not suggest either for a truck.

 

Thanks for the info. Lightweight pulleys just interested me because I'm very interested in cutting weight from as many places as I can while maintaining everyday comfort.

I suppose I'll look elsewhere to cut some weight...

 

I am looking for an underdrive pulley but can't find one for a 4.0 tacoma? It is worth it if you go about 25% under. You won't notice any ill affects and you will get a good a little kick in mpg (1 orso) and power (7hp orso) and accessory life. 25% longer life!

 

I have been looking for Under Drive pullies for over a year. No one makes the basics for us yet.

Pulley
Software
and so on.

 

I have underdrive crank pulley & lightened accessory pullies on my P5. 4 cyl auto. Have had ZERO issues or any differences at all with overheating or dimming electrical shit or pwr steering issues or AC issues.

 

Where are the 4.0 under drive pullys. I have not been able to find them in over a year of searching.

 

Mazda P5....none on the Taco.

 

That sucks! I guess no one makes any for the 4.0 Tacoma's. I'll bet there are some for other applications that would fit, I don't know how you would figure out which one would work though.

 

Don't know if anyone still checks this thread but look at Nonstop Tuning.

 

Is there any update on it?

Lat I heard was people got it and were going to report back.
