Eagle rods?
- Thread starter gsx750r93
- Start date
So sorry ended up finding it.. Mod please delete
I think where the stock rods have failed was at high RPM and high HP numbers. (Like launching at 7000rpm on a large turbo engine.)
Also most stock rods seem to fail at the oil hole in the rod journal. (Not the pin bore hole.)
Do the Eagle rods have the oil hole on the rod bearing like the stocker? I know the Pauter ones do not, but have the hole on top like the stocker for pin oil. (I like that Eagle puts it in a lower stress area on the side in an area with more material.) I think not having an oil hole on the rod bearing area helps to keep oil in that bearing better, and should lead to fewer problems with spun rod bearings/knock issues. (Keep in mind that rod bearings are harder to oil than mains due to the rod journal throw distance from crank centerline. This rotating/centrifical force slings off the oil that has to lube your rod bearings, and I never liked the idea of helping that oil to escape by having the oil squirter holes on the stock rods.)
That being said, I have the Pauters, and like this Eagle option. (I've been told that for the stroker motor, any 6" rod will work as the stroker uses 327 SBC rod bearings anyway, and you can either use Honda pins, or SBC pins since the pistons are being done custom, you just have ROSS provide the pistons with the right sized pins for your rods.)
I've heard good things about the Eagle stuff. And the costs are pretty reasonable from what I've seen. (Too bad Eagle does not make a nice 3.4L stroker kit for the 7M and 2J engines. They would sell if the prices were anything like stroker kits for other motors I've seen advertised. They could also address a few issues higher HP engines have found.
1) Increase the crank oil hole sizes. (Larger drilled passeges.)
2) Forge the crank with windage in mind.
3) Forge the crank fully counter balllanced like the 7M one, but make it with thinner webs to match the lighter Eagle rods.
4) Have the option of a stroker 98mm throw, using SBC bearings, and 6" rods as outlined. 98mm stroke on 85mm bore is a very nice engine indeed. (Great for tourqe, and not too bad HP wise either with a very usable 7k redline limit.
Thanks for the pics.
