Hey all I was wondering can either ROCK or Mitsiman tell us what they can do with the lack of pulleys with our lancers and if they can remedy the problems (since unorthodox is taking wait and see) I would greatly appreciate your feedback since as far as I can see your ARE the major players on the lancer game. Thanks in advance

 

I was always under the impression the under drive pulleys were bad for the car.. like they mess up the alternator and AC?

Any truth to it?

 

underdrive pulleys aren't necissarily bad for the alternator and the AC. people just get disappointed cuz their ligths start to dim or the AC isn't as cold. but the way i look @ it is that u shoulda knew that from the start. just like the name states, the pulleys underdrive the accessories. it frees horsepower by driving the accessories @ a lower rate.

maybe some pretty looking stock sized ones would be better cuz many people just want them cuz they look pretty or even lighter ones...

 

How much HP can you free up with the pulleys. Is it worth not haveing the coldest AC. or bright lights?

 

well first of all u gotta think about which pulleys you are gonna get or gonna install. i mean some kits use the alternator some use the ac, some even use the power steering. hell, first of all, i ain't driving my car with reduced power steering...that would just plain suck for the way i drive...

but back on topic its really hard to say how much you'll save. i mean it all depends on which pulleys u install, and how much lighter they are, how much they underdrive the accesories and ov course your car.

but for my, not for my car if its the underdrive type. i'll run into problems with my accessories getting power. i'd get for my car to go dim when playing my system or running all my lights. if its teh pretty show type, maybe one day if my pulley goes bad or i start hitting car shows and stuff with my car

 

Electrical components on the car, especially the ECU or PCM, are designed to operate within a specific voltage range. Usually, a little over or under and no problem. However, you may want to be concerned at night or anytime a very high electrical load exists and the alternator is underdriven. I think you'd have more risk than reward with a setup like this.

The Lancer doesn't have a 150 amp truck alternator producing boatloads of drag on the engine. It's a small(er) 80 ampere unit probably made by either Denso or Hitachi. If we had a large amperage unit installed as stock, with a lot of excess capacity, then I'd say go for it.

Again, I think you'd get minimal results on the A/C system if there was an underdrive setup available, and probably warm enough air once underdriven that it wouldn't be worth running the A/C in the first place. Solution: If you're that set on the idea of minimizing losses from A/C, don't run the A/C.

I think that for some of the reasons above, you're not seeing mfgs rush an assortment of pulleys to market. Pulleys look pretty underhood, but deliver very little performance gains on our 120hp cars in relation to their cost, installation pain, and potential warranty woes.

 

Honestly not a big fan of pulley for a lot of reasons. Waiting for AEM to make them. That is probably the best option for us all to do.

I am of the same agreement not a big fan of them. I have made undersize harmonic balancers for race cars only because we had to make them for the vehicle anyway (The harmonic balancer) but other than that no it is not something we would necessarily get into at this time.

some reading for everyone:

I have known a few people to put the pullies on their car's, but took them off a couple of day's later because the gains were very minimal and down south the a/c is needed alot of the time... and you can forget having them if you have any kinda audio system definatly would not recomend it.

 

You can maintain AC. The idea is to reduce rotating mass.

 

OK, I understand that we're avoiding the smaller pulleys.

But what about lighter pulleys? Simply taking a stock pulley and having a company fabricate it out of aluminum shouldn't be too hard for a large company like RRM or RPW. I question whether or not AEM will ever get around to making them for the Lancer.

 

I agree, I think that this would be nice for someone to look into, i've seen really good power gains (well the freeing up of power anyway) on quite a few different types of cars so I know its not just something that happens to hondas.

I am running an underdrive pulley. I did notice some seat-of-the-pants horsepower gains, and the only con I experienced was that my A/C would not blow as cold at idle. It still blows cold, just not AS cold.

 

OK, let's just accept that AEM, RRM, and RPW are passing on this one and shoot for NSN to make some.
