I'm rebuilding a dart block. The oil pump exploded on the dyno (at only 486whp). Unfortunately it fucked up the crank. I proposed to the client that maybe we should put in an Eagle crank. Then I asked around and a few people have said that they're not even as good as the OEM honda cranks. I've never really had a problem with an OE crankshaft but I wonder if these eagle parts are as bad as some people make them out to be or if they're just a bunch of internet parrots repeating one person's bad experience? -Michael

Like anything else, I think its how its built and checked.

Just found that scat makes cranks too. A lot of engine builders seem to find them more consistant than the eagle products. I may opt for that one instead. -Michael

why not using OEM used crank? For which car are you looking for? usually cranks are from $50 to $150, depends on aplication. Is it relly worth to go for new eagle for $600 or even more???

Golden Eagle sells polished LS craqnks for $100 shipped, good deal IMO. Honda has some of the best parts quality among all auto makes, so its hard to beat. People claim the stockers are twist-forged steel, as well as nitride coated (down .0010\"). BTW was the block ever align-honed? If the centerline changed at all, that means the gear is off center and will bind. That's what usually blows the oil pumps. The other leading cause, which some dismiss, is the undampened CTR pulley. IMO the best way to go is the 'superdeck' a B18, resleeve, and enjoy the better quality and money savings over Dart.

His failure was due to an underdrive pulley I never thought to check for. I didn't do the original build. I've seen this a good 1/2 dozen times. Replace with an OEM pulley it lasts for years. In his case he absolutely wants the best stuff available. -Michael

i know a engine that make a lot of power with an eagle 92mm crank

If he wants to go all-out, get the Eagle, then have it checked for balance and all journals for roundness. I've heard some people claim theirs arrived out of spec (for a Honda crank), but they probably won't have as good of quality control vs a Japanese factory making literally millions of cranks.

I ended up ordering a scat from xenocron. It's american made so I hope it's better than something done in China. Will let you know when she's back together and on the dyno. -Michael

if he wants the best stuff he shoulda gone with an OEM crank..
