I don't really stilll understand if the Main pulley work, can anyone help me??
I will norice the difference??
It will increase my Hp, and will give me any problem or any loss of performance in some accesories???
Tanks guys

 

I was also wondering the same thing, I got the RP main pully. I was wanting to know if it lowers the volts so much, to start making things cut out at idle. Just curious, I'm going to install it anyway, if it does.

 

I got the RP pulley and the lights dimm a little when the car is idling, this is also with the alternator pulley and a new alternator. No big sound system either. However the car idled better and it the pick up was slightly better as well.

 

I have the underdrive pulley on my GTU and my GXL. Lights are dimmer at idle, stereo at 500 watts RMS starts cutting out after 5 minutes or so at idle. In the GTU I don't have the stereo and everything is great! I am pleased with the pulleys. I just can't idle and let people crank the stereo for hours....

 

Appreciate the reply guys, I can live with it the radio cuttin out every now and then.Guess it's all in the name of "power". Gotta have it. Thanx again.

 

underdrive pulleys only require a high idle. I think maybe 1200-1400 should servise. I have a 2K idle with a bridgeport because thats were it wants to, so I never have a voltage problem. h he. Also I believe when warming a engine up or idling a long time at a low rpm can cause mildheating if the water pump is turning too slowly. Thats my guess.

 

I have the Power Pulley(CL-12144) from Ray (Shane Racing) with stock pulleys on the rest. It slows down all the pumps and alternator. But, the alternator still peforms with 12.8V at idle.
No light dimming here.

 

FD's have a different alternator than FC's . That's why!!!

 

Could we possibly put a "better" more efficient alternator on the car if going to a pulley like so, maybe even without going to the pulley, just have a better alternator.

 

100 amps, but you gotta do some re-wiring.

series 4 TII=70 amps
series 5 TII=80 amps

series 5 alt. would be easier to do!!

 

How did u guys get the pullies on.. I have bonez pulley and mazdatrix alt pulley. I put the car in fouth and had friend lock the brakes as well as the parking brake and put some stopers on the back tire. Still when i used this huge 3 foot ratchet I could not get the pully nut off. I even broke some socket i was using. The car still backed up to. This thing is crazy tight. I tried the Starting car methad with the wrench on the frame but battery and starter wasnt powerful enoughf. Any sugestions.

 

do you know what would have to be rewired, and would this help regain some idle power w/ underdrive pulleys.

 

you carnt gaurantee that you wont loose the needle berrings even if you are careful take i out and put it on the flywheel then you will be alright
i changes m frount cover and and them put it back on the floor with out the nut done up and pinched the berrings ,100 kms later she seazed solid costly mistake shhould of known better

 

Are you sure you need to loosen the main bolt to install the Bonez pulley? If you have a third gen, the Bonez pulley bolts to the stock pulley hub, so you don't have to fight that sucker.

That is my engine on the Mazdatrix page. Trust me, you don't want to screw that up!

For the alternator pulley, just take it to a garage and have them hit it with an air wrench.

If you change the main pulley, it will slow down mani accesories: one of wich is the water pump, it eliminate the problem of cavitation, but at idle in hot atmosphere (as Texas or south Italy were i live) in the traffic, it will cause overheat due to the slow circolation of water.
In the U.S.A. the road are different, here there is a lot of traffic.
That is my idea, if you think is incorrect, tell me i can change my mind, but tell me why.

what about an electric waterpump to put even less of a job on the pulleys.

 

You will give less jobs to the water pulley but you will increase the job of the alternator pulley, so i think is unusefull.

what about gettin a better alternator like I mentioned earlier. Produces more power for same amount of pulley spin if I understood that right, which means hopefully it would work just fine.

 

You should get more peak HP with an electric WP because it will pull from the battery during the HP run. The battery works like an accumulator -- the electric water pump would be less efficient overall, but it is decoupled from the motor, so it won't sap as much power when you're on it as a mechanical pump would. I think.

i really liked the link but man i am confuse. The thing is that the shaft must not rotate while you remove the main pulley. To do so, you just stick the flywheel in place which is attached to the shaft. And then, you shouldn't have any problem. Is that it?

Please tell me a little more about this, i want to get the unorthodox full pulley set and want to replace the main but don't want to screw everything.

i have a 3rd gen by the way

thanks a lot

I allready have a Pettit underdrive main pulley, and I want to add a set of unorthodox accessory lightened pulleys ps,alt,wp. Would I have a problem using the under drive main pulley with the lightened accessory set?How much of a HP gain is there?
