Serpentine ???
Must a tensioner be used when running a serpentine belt?
I want to do a conversion. Water pump, alternator, and crank. Photos anyone? Help? Suggestions? Thanks, Dave |

You need some way to put tension on the belt. Some versions use a spring-loaded idler pulley; you put the belt on all the pulleys while holding the idler back against the spring, release it and the idler keeps the belt in tension.
Other versions use a idler that slides in its mount for adjusting, but then you tighten it down into a fixed position. Others may use one of the accessories in a sliding mount as the tensioning device, then tighteneing it down. My cars have the spring variety and all the accessories are in fixed mounts. George |

I assume your are saying you have one on your Pontiac? From which vehicle did you take it from and did you have to do anything to make it fit your Pontiac?
Thanks, Dave |

Serpentine
I have a March serpentine system. Tension is obtained by lengthening or shortening the AC or alternator adjusting rod. There is no tensioner.

Need serpentine?
A friend of mine is close to releasing his serpentine system for Pontiacs. He is a retired engineer, and he has already done these for Ford and Chebby.
I have the laser-cut prototypes in my truck. He should be doing the final test fit in a week or so. It's a nice set-up; all the parts stayed in more or less their original positions, just tucked in nice an close. It will minimize re-wiring and re-plumbing. Any interest? Bob Trimpe |

Depends on the price. A REALISTIC price, or look at my billet @#$@#$ price.
I'd love a properly setup serpentine system.

Serpentine
I will try to post a picture, never have before so it may not come out. Can actually see better pictures on the March performance web site.

It's not my product - I'm just the beta tester. Dan moves at his pace, but I did remind him that he has interested potential customers.
I have to honor his requests to keep it confidential. He mentioned that he hopes to file patent apps in a couple of weeks.

I have a ROdnry Red setup on my motor. Alt, h2o, ps. Looks nice. Good fit. Uses factory style tensioner. Haven't started motor yet so not sure how it will run. But should work just fine.

The serpentine system is progressing nicely. I hope to have pictures of the mounted prototype by next week.
This is laser-cut stainless or painted steel .25" plate. What do you guys consider a reasonable price? Has hasn't set one yet. Bob |

A well engineered, complete kit starting around $600 would go over well here I think. What sort of finishes is your buddy thinking of? Chromed (=$), painted, black oxided (steel), anodized (Al)? Perhaps others can chime in with their $.02 jamie

March part # 13100 is $395.95 at Summit....... so a new product comming to market needs to beat this price!

I think he's looking at stainless or painted for this first pass.
I'll pass along the price points. As sson as he rolls out the prototype, I will point him to this forum, and he can begin fielding questions from interested people. Stay tuned. |

Here's the breakdown on the march kits from summit. $395 - march system (crank, water pump & alternator) $599 - march system (crank, water pump, alt, & press fit ps pump) $645 - march system (crank, water pump, alt, & keyway ps pump) $999 - march system (crank, water pump, alt, keyway ps pump, & ac) I agree with JC, function over bling. But I do like the turnbuckle type adjustment rods for belt tension over the other options.
