en tout cas 150 run c'est vrai que ça fais pas lourd pour le prix de la chose
Boarf, finalement, regarde: j'ai fait en tout et pour tout 11 runs à Lurcy...Un de plus que prévu puisqu'il y a eu un run qualif de plus (un sans chrono...) Donc 10 runs par course quand tu vas jusqu'en finale...5 manches ATD par an...T'as trois ans devant toi, à condition d'aller en finale à chaque fois, sinon ça peut tomber à 4 runs par course: trois qualifs, un round éliminatoire et zou, plateau...20 runs par an ! Tes bielles vont tenir 7 ans et demi !! Et y'a des années où y'a que 4 courses, à l'ATD...Si tu gagnes pas une seule fois, tes bielles vont tenir 10 ans !!! Et les changer tous les 150 runs, c'est comme qui dirait "conseillé", mais si t'es un sagouin, tu peux viser les 200 runs...Autant dire que tu revends ton moulin bien avant d'être au bout des runs de tes bielles !!:whistle:
Et si t'es en finale à chaque fois, avec l'oseille que tu prends, tu peux t'en acheter un stock, de bielles alu !!! :P

The Only Streetable Aluminum Rod
Urban legends abound in the gearhead community. One is: aluminum connecting rods don't work in street engines. Prior to the mid-'70s, that might have been true, however, introduction of the Bill Miller Engineering Forged Aluminum Connecting Rod in 1975 provided an exception to that myth.
The BME Rod has great durability in high-end, high-power, street/strip or hot street engines because it is die-forged, rather than cut out of a plate. Bill Miller Engineering's unique, aluminum alloy further enhances fatigue strength such that the durability of BME Rod rivals that of many forged steel rods and exceeds that of a few.
About 20 years ago, a few resourceful engine builders, led by H-O Racing's, Ken Crocie, began using BME Rods in very-high-performance street engines. Crocie, a racing and street/strip Pontiac V8 specialist, faced with a shortage of acceptable steel rods for Pontiacs, began to use BME Aluminum Rods. While a few other engine builders followed Crocie's lead, admittedly, use of the Bill MIller Engineering Rod in street engines has not been widespread, but that's only because of its higher cost and the stubborn belief that any aluminum rod is unsuitable for street use.
"In a street application, using the aluminum rod is a no brainer," BME President, Bill Miller, recently said in an interview with an automotive magazine. "I don't know how the myth that aluminum rods can't be used on the street got started, but I'll guess that, back in the 60s and early-70s, they weren't making them using the process we're using, today. With the material we've got and they way we manufacture the connecting rods, they'll live a couple hundred thousand miles on the street because a street application is, for the most part, low load. Our basic Aluminum Rod is made for 10,000 rpm and 800-hp. The design criteria for the connecting rod is way overkill for what it's going see on the street. We been running aluminum rods on the street for 20 years.")
