anybody use the MR pulley set? - Page 2 - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Of course there are easier ways to make 5hp, Im just saying anyone one know what the turbo sr20 does. Reason for that is Fd-rx-7 gained I think 17whp a z32 gained close to 25whp from earlier readings I had seen. Im wondering if the turbo sr makes close to 17whp with a simple mod as this.

I had an unorthodox on my z and I seriously doubt that it gained 25hp from it. More like 10hp.

I just think the only reason to get these are to clean up the engine bay. I bought a greddy set just for that reason.

Any power gain is questionable.Though I dynoed my car before i had the pullies i doubt i made almost any power.

I mean don't call me retarded because pullies this, pullies that. I have them. They look nice, thats it.

A nice balanced crank pulley though increases engine wear slightly (as with most any mods besides breathing ones) is the only pulley you will see real power from.

I love spending money on rice mods.

im not getting it if theres no gain

From an underdrive crank pulley you will get a gain. Usually in the 5-7 hp range. It's been proven about a billion times.

As others have pointed out, you can realize *much* larger gains on a turbo car with other mods in the same price range -- a used boost controller immediately comes to mind...

For NA cars, an underdrive pulley set is the next logical upgrade after intake/exhaust/headers. After the pulley, add a lightened flywheel, aluminum driveshaft and lightweight wheels for maximum effect.

The greddy ones looks nice though. MR is that nasty maroon color. Even for looks those pullies look bad.

Yeah, I'm not saying it should be a top priority. There are alot of things that could be better investments. I was just saying there is some gain, because he said "I'm not getting one if there's no gain".

im talking about the mr pulley set which the thread is about not underdrive pulleys.

Agreed. Spend the money on something else.

I have had lightened pulleys on N/A cars and it def. feels like acceleration has improved. Not sure if turbo cars would have the same feeling since acceleration is already good. Also, Enjuku Racing said that there is an issue with the MR PS pulley. "Please note there is a slight issue with the PS pulley and a small socket or larger hole needs to be used to tighten the pump" Not sure what all that is about but I am having a set installed by the shop that is doing the swap for me, so I figured that they can handle this. Please let me know your experiences if any with this set of pulleys. For the money, it seems like a nice mod that will brighten up the engine bay as well.

Also, can someone define "cavitation" for me? The Yashio factory said their water pump pulley helped in stopping cavitation.
