Aluminum rods!?
Anybody have any input on aluminum rods ? Mostly track use truck maybe cruis around looking for imports once in a while. How long would I expect for life span on a aluminum rod at about 15-1600hp in a cr??? Any help would be appreciated

Gonna really depend on how many passes you make. I wouldnt expect to get more than a season or two out of them. Why do you want AL rods?

Milliken just smoked his with low oil pressure, not really the rods problem. He's 2500+ and makes a lot of passes

I would be glad they were billet steel rods in it and not aluminum. My guess their would be much more damage if so.

Aluminum isn't a good material choice for rods because they will fatigue. Esp in a long stroke high torque engine.

Top fuel replaces them after every pass.

And they're making 12,000hp so every little thing counts.
OP. Use steel rods. No need to reinvent the wheel for 1500hp.

I know why they are replaced. Those engine are a controlled explosion. I was only making the point that top fuel was nowhere near a proper comparison to a Diesel.

I was agreeing with you. Just reinforcing that they only need them because they are going after every last drop.

The +1” steel rods in my deck plate engine are only 84grams heavier then the stockers I just pulled out of a customers engine. I’ve had v8 international garbage be off more then that on one assembly. In other words if weight is a concern, there are some decent steel options out there.

To be fair, a rod in a V8 engine has a much easier life than a longer stroke straight 6 and isn't a very good comparison. The difference being close to 1 inch longer stroke puts a lot more stress on parts.
