ribbed belts for the 215
Has anyone pieced together or seen a simple 3 pulley ribbed belt system for the 215.... Not serpentine. But just a single belt with crank, water pump, and alternator pulleys?

Re: ribbed belts for the 215
I had to put this together when I put the Vortech blower on my engine (LT1 Chevy) since the stock position of the alternator would be through the hood. Built everything off a 5/8" thick aluminum plate and spaced the accessories off of that. Requires a lot of measuring to get everything to come out in the same plane. Lines show the belt path.

Re: ribbed belts for the 215
Funny enough they do!
Got one from Summit a while back. Made by Meziere. Haven't used it yet but it's a good looking part. Cheers Fred |

Re: ribbed belts for the 215
Meziere is who made the pump I have on the engine. Seems to work well but haven't taken it on a long drive yet. Two belts - one for the blower and the other for the alt, and p.s., one fixed idler and a tensioner.

Re: ribbed belts for the 215
JIm.. Was your MG featured in a Petersons publishing book around 1975 called..." The complete book of engine swapping NO 4" ?
In the article they oulined a Olds 215 swap.. but the pictures look more like a Buick 215. This is the same book that gave me the inspitration for my alumium V-8 vega swap. |

Re: ribbed belts for the 215
That was the car and me looking much younger than I do now. The press is notorious for getting things wrong even when you write it out for them like I did. The original swap was a Buick naturally aspirated. After a couple years I came across an Olds Jetfire turbo engine and put that in. With a few mods like lower compression, a different cam and wastegate mods it made 15 lbs boost and went like a striped ape. I drove it as my only car for 10 years. A friend crashed it in 1980 and it sat until 2001 when I began the widening project.

Re: ribbed belts for the 215
Still wondering about this.. D&D USED to make them but long story short they arent currently making any more and are out of stock.. anyone have a set they'd like to sell?

Re: ribbed belts for the 215
Last I saw it listed it was $450.. It included all pulleys brackets and chrome plated alternator.. That was 2007 price.

Re: ribbed belts for the 215
I would imagine that the alternator pulley is an off the shelf item... But the crank and water pump pulleys are custom. Id be happy with a CAD file or a 3D printing of them at this point.. something I could bring to a CNC shop.

Re: ribbed belts for the 215
The crank pulley will need six mounting holes. I don't know, but I've got a hunch that some sort of Buick 3800 pulley might work. This page shows a 1986-7 Buick Grand National crank pulley: [www.jegs.com] and this page shows a whole billet pulley set for a Grand National [www.cottonsperformance.com]
To get alignment just right, the four bolt flange on your BOP215 water pump may need to be shifted with a press. Or, you could possibly shim one pulley or the other outward. When I added a trigger wheel between my harmonic balancer and crank pulley (for my electronic ignition installation), I made a simple spacer to move my water pump pulley outward and I also made a new alternator pulley bracket with more offset. |

Re: ribbed belts for the 215
The cottons performance stuff looks nice...
In trying to figure this out I had also thought I could just run the Buick V-6 stuff.. While the crank pulley might work all of the water pump pulleys are smooth since the pumps are reverse rotation the back of the belt runs across the pulley.. No ribs.. from the looks of the drawing the alt pulley in that kit may also be smooth.. Although that pert of the puzzle is simple since I know March makes a grooved alt pulley...  Edited 1 time(s).

Re: ribbed belts for the 215
I'm not really clear on what you're trying to accomplish. Is appearance the driving concern, or some aspect of performance? Are you hoping to slow down the water pump or alternator?
Have you thought about rigidly mounting your alternator and adding an idler/tensioner to the mix? Doing so might achieve a more consistent and predictable belt tension over the belt's life. |

Re: ribbed belts for the 215
I like the durability of the ribbed belts... I just cant seem to put anything together with existing parts.. The Buick V-6 pulleys are all for reverse rotation.. Not going to work with my application...

Re: ribbed belts for the 215
I made all my own pulleys, but used a fluidamper from a Jeep for the crank and cut another groove in it. (My blower already came with an 8 groove pulley which I used, as did the A/C compressor.) That smooth water pump pulley may be thick enough to cut the grooves in it. I'd look at that first.
