what did that flywheel end up weighing?

 

the belt shouldnt squeel anyway, alot of motors rev faster without an issue, considered issues with alternator?

 

He's got one of those 80amp VL jobbies so I reckon that'll be the cause!

i think it was 2.8kg lighter.

they idle was 1000rpm till now. currently 600rpm

 

i had a vl one till it kept cooking regulator.

 

also I'm running a pulley thats about 20% smaller. i also had the same problem running a bigger pulley.

 

Have you tried a standard k motor alternator? Did you do the alternator modification for big stereo reasons>?

the one i got in it atm is only a 55 amper. i got a free alternator so i was like why not. I'm running a huge stereo

I'm a man who can appreciate Highway to Hell on full song. :rocknroll:

just bang a standard one back in there and see what happens, not too hard is it?

mmmm, big stereo. Does the belt slip if you have the stereo turned off?????

 

I ask that as when I was running 100W high beam globes in the headlights and 100W driving lights on my Rolla, the load from the alternator used to slow the motor down a few hundred revs. An amp would be drawing a lot of current so it might be adding to your issues. For grip you should be running bigger alternator pulley anyway to get more belt wrap, and will slow your alterantor down so it doesnt drag as much power to turn it.

i had my stereo off the last 2 days. might try unplug the alternator and take it for a spin.

 

doesnt slip till 4grand, then it makes your ears bleed

mmm, smaller pulley doesnt make sense if you like to rev the motor alot...

smaller pulley means it spin faster therefore more output at idle etc etc?

 

you might be on to something. ill swap em over next time i get a chance and take some pics

but increased output will account for the need for more output at idle

Put a switch in the system and when it slips to bad flick the alternator off. Not charging, so no load, and shouldnt slip. Just remember to reactivate the alternator though.........

 

Was going to do the above to my club car but it was specifically banned in the rules :(

 

Hey if you are handy with electronics maybe you could set up something to do this automatically.....

Your alternator is a 55 amper, at 12 volts (lets forget efficiency AC/DC for the moment) that works out at 0.66kw of power draw. Your motor will definitely produce more than that at idle.

 

Varying the speed the alternator runs at wont vary the load; your alternator will only draw max power if you're using max power. ie, subs kicking, spotlights on etc. From a quick google, most people seem to be able to generate 90% power at idle anyway. The factory pulley size is probably designed to put the max power draw at an ideal rev range in order to be it's most efficient.

 

But what you ARE doing is changing the torque required to drive the alternator, by reducing the diameter, you've increased the amount of torque required at a given load.

 

Definitely change back to a stock pulley.

 

 

I paid 20 bucks for a 5K flywheel definitely don't pay more than that. Having flywheel bolts fail on me previously, I would also suggest you get a brand new set of flywheel bolts, not some hacked ones the wrecker sold you.

I had same issue with the alternator squeeling.. but fixed that easily.. Umm, i shaved my flywheel before i put mine on the road and now that thing f@$king hammers out with its rev's.... i also did the same to my toyota crown.. Thing was a beast..

pro's and cons of doing it is as usual but i think pro's outweigh the cons.. SO DO IT!!
