Isnt the minispeed one a lot more expensive? yes, but I can get it for the same price as the MED chain kit. MED's got 2 votes now. im sure vizard prefers the belt for a "money no object" build, but duplex verniers as the next option down. |

I guess the belt is lighter and quieter,but ultimately the chain is more reliable.I have only ever used a duplex chain with a tensioner and never had to replace a chain or tensioner on any engine I have built,nor do they ever "tinkle"(Now I suppose I wait for the usual rain of comments)Pun intended. |

a belt is nice in a high revving engine as it doesnt transfer harmonics to the valve train- being rubber, but its almost twice the weight of an chain as it has steel sprockets and a massive cast alloy backplate
I seriously doubt it! |

2-3hp? No way. The fan is in the region of this and that is obviously more power sapping than that small chain.

a few years back i won a non adjustable belt drive on ebay, apparently off a miglia racer, the crank pulley (they were made of some cheap alloy) was worn beyond use, not sure if this is still an issue with them or not? "Turbo's make torque, and torque makes fun"

Ive got a belt on the van and it appears ok but I paid diddly for it so didnt have a good reason not to use it.
Minivanless, but reluctantly happy living with the decision. There'll be another one day.

Belts degrade over time and need to be changed at regular intervals. 3yrs max in my book. Plus they stretch and are vulnerable to damage.

Thinking about the size of that cam pulley and the new rubber seal - this is a potential area of weakness in terms of oil leakage as the front plate on many belt drives does not have an engine breather like a chain set up has on its cover. I've modidfied the belt cover on mine so that I can inspect the belt without taking the cover off. The TDC marks on the cover plate are also sometimes out of place when you time the engine by strobe so I machined my own before fitting the cover on. Spare belts are easy to get hold of so I'm looking at one every 15-20k to play on the safe side. Seeing as I've only done 1100 miles since the Minimag photoshoot in June, that'll be one every 16 years then ! Richard. Edited by Si P on 26th Dec, 2008. I drill holes in everything..! |

I'm sure belts on modern cars are there purely to keep servicing departments in business.

Yes it is, but I dont have access to machinery at the moment to make sprockets so it would cost a fortune Paul I seriously doubt it! |
