Crazy how its BARELY bent, but, it IS bentEvery motor I've seen with bent rods was torn down for a build and had been driving fine previously, some had blown with cracked pistons/rings, some were just building for more power. A lot of them had random misfires that never showed up in logs, or consistently bad timing corrections that influenced building for safety. Power was usually fine as was drivability and fuel economy etc. Alex at ABR or Tony's builder could probably comment more, if I had to put a number I'd say 10 out of the 15 or so I've seen before/after of in Houston and Florida have had bent anywhere from one to 3 rods. Nobody really talks much about it.
Any of the actual engine builders would have better numbers probably but I think it's pretty common. I will add that building the motor won't fix corrections, it always makes them worse with false knock. Good times lol.
Edit- it can be subtle, like here:
+about 25% for dynojet so around 630whp
leak down test wont but a compression test will as the comp will be downAssuming there wouldn't be any tell tale signs of a bent rod during a leak down test would there be?
Well that's a good sign i guess...compression test results wereleak down test wont but a compression test will as the comp will be down
A leak down test will show bent valves, cracked rings or ringlands or any defects in the combustion chamber like a cracked bore and such.
Sometimes the damage can be so small and only a teardown will reveal whats going on.
So if the tuning hasn't changed there is something mechanical going on and you have to keep looking to find it or it could be just the fuel supplier.
