Hi-PAC original SILVER TOP ALLOY PULLY  

eBayオークションで購入しました。

台湾のメーカーが出品しており、
重量は純正比1/4以下で、慣性モーメントを低減させてレスポンスupを図るものです。
純正品にあるようなゴムのブッシュはなく、振動を抑制する効果はないと思います。

精度もかなり良さそうで、出来上がりが楽しみですv(^-^)v
これで効果が出てくれれば御の字ですね☆

送料込で10280円でした。



These pullys were made by forged aircraft alloy of 7075 material as you can see in the photo 2(NOT ONLY TURNING FROM FORGED ALUMINUM ALLOY MATERIAL BUT ARE ALSO HARD ANODIZED FINISHED).

Spec:

Meterial:7075 T-6 Aluminum

Type: Forged Alloy

Diameter:Same as original

Finish:Hard Anodize Gold MIL-8625 TYPE III CLASS-2 THICKNESS:0.002"

Test laboratory: SGS Taiwan Ltd.

Fracture strenght:54569kgf

Hubdue strenght:510kgf/mm2

The anti-pluss strenght:560kgf/mm2

Hardness:Micro Vickers 180



This alloy pully diameter is same as the original but the weight be reduced to only 386 gram and had be fully balanced, this means that you can get more extra 6~10 hp power from your engine and much quicker rev response of your engine but no need to change the length of your engine belt.

The most important of the hardness and strength are couple times over than normally alloy products on the market NOT THE CHEAP CHINA PRODUCT.
