Performance pulley's for an sc400?

[jibby]

Hey, I hope I am not making everyone nuts with all my posts I will chill soon I promise, but got one more question that needs answering and this is after using the search option and finding little info but nothing much. I currently have easy access to my stock pulley's and I was wondering if there is a complete set of high performance pulley's designed and proven to perform for the 1992 sc400?

If so is it worth the money/hp gains/time/labor/-weight/et... to install and get any kind of results??? I remember doing this on a few Chevy small block V8 engines (smaller pulley's) and did get some results but not always good ones like problems with dimmed lighting, cooling, etc.. or something... Just wondering what is up with this????

If you replace the standard bearings on the pulleys and the cambelt idler bearings (2 just above the crank pulley) you'll get better performance. Its one of the 150,000kms service things to do that most people don't do.

Its like the question which is the better performance oil. Regular oil changes is the way to get (and keep) better performance.

Given the cost of aftermarket pullies and the nominal power increase (if any) they look like a bad investment.

They have a certain bling factor that may make them worthwhile to someone after the looks.

Actually, to get an advantage you would use a smaller drive pulley (crank) and larger driven pulleys (alternator, PS pump) On most engines the water pump consumes a good amount of power but on the xUZFE engines the WP is driven off the timing belt so no advantage is available on that component.

Now, some have gone to a smaller crank pulley but extreme caution should be advised against going without a harmonic dampener. I will not repeat the reasons why as there are many links in many posts and a search will answer all such questions.

Simply going with larger PS and Alt pulleys may free up a few ponies at the possible expense of poor charging at idle and poor PS performance at low speeds.

Thanks guys I did read up on the crank pully swaps and I guess there is a dampener problem so forget that idea... and yes the assessory pulley's would be larger to free up power and inturn will slow down the effeciency of let's say the Power Steering, Alt,etc.... I don't think I am going to mess with any of the pully's except for maybe the power steering pulley if anything, the other stuff I do not want to lessen the power outputs.....
