Title: Best aftermarket pulleys? Post by: beetletom on November 06, 2018, 20:00:37 pm I?m after black anodised pulleys for my engine.
What is the best type? The Saco pulleys look ok? And the billet spin true top pulley you can now buy? Or am I better off getting a genuine Vw bottom pulley And a genuine Vw alternator pulley? Which I have on another alternator But getting the back part off without warping it would be difficult? Title: Re: Best aftermarket pulleys? Post by: Jim Ratto on November 06, 2018, 21:20:25 pm for generator/alternator, I feel the FLAT 4 pulley is best made. Better than the last OE VW pulley I bought about 10 years ago.
No defects with FLAT 4 pulley, at all. Title: Re: Best aftermarket pulleys? Post by: beetletom on November 06, 2018, 21:44:55 pm Cool thanks, had no idea flat 4 even did pulleys!
But we only have very limited parts from flat4 stocked by uk suppliers ??? Title: Re: Best aftermarket pulleys? Post by: Richierich56 on November 06, 2018, 21:49:27 pm Genuine Bugpack Spin Tru are good - if you can get one.

I also have an OG Std sized Suntana pulley I?d found decades ago but never used. Are these worth using? Title: Re: Best aftermarket pulleys? Post by: spoolin70 on November 07, 2018, 20:06:48 pm Have you looked at CSP pulleys ?
Haven't used them myself but seen a couple on other engines and always look good quality. Title: Re: Best aftermarket pulleys? Post by: NAO on December 14, 2018, 11:04:47 am We (FLAT4) even made new tooling to improve...new one is even better and it's on the way!!

Didn't think they could be improved upon. Title: Re: Best aftermarket pulleys? Post by: 63 ripper on December 15, 2018, 11:26:44 am I've had two Flat Four pulleys now, a gold one when they first came out..probably 7 years ago, great quality and is still on the car now. I bought another earlier this year, it came in black. The back half was a little loose on installation, as I was taking it off (by hand) to inspect, the outer ring actually broke off leaving the hub stuck on my alternator. When I finally got the "hub" off it looked to me like it was plated 1st then pressed together, causing a weak spot. The seller sent me a new one, gold this time which is a better fit but I don't have a lot of miles on it yet so can't comment. Interested to see what the updated design is.

Not sure about a conventional Vee belt but suggest you dont go with a serpentine system!! http://www.offroadvw.net/tech/wes/fan.html Long and short of it is that the vee belt slips ~4 to 4.5K engine rpm however that isnt a problem as the gain in airflow vs actually cooling effect isnt worth it! AND to double a fans speed takes a cube of the power! The serpentine will definitely spin the fan faster but also take a boatload of power away from your right foot to do so!! |
