True limits of gen 4 rods hp wise
Yup if you check the plugs and they are good, pistons are good, and only a rod is bent then you were just making more jams then the hard parts could hold. Now that said if the guy didn't want a max effort setup then boost control should be implemented to stay below the hard parts limit.
Gen 4 pistons and rods are both strong enough to sustain 1400+hp for a 1/4 mile blast at a time. Jon was putting 100+ passes on his running 170-178mph through the stripe shifting at 8200-8400. The only time he has bent them in the last 300ish passes doing this is when he lifts the heads. He believes he is simply "hydroing" them when the water starts entering the chambers.
This is my plan.... Plenty of 4.8’s in my area with 120k or less for $500, New Hampshire winters are great for something besides skiing! I have already committed to smoking my first few engines while I learn to tune.
My SBE LS1 has been alive at almost 700whp for going on three years now so I'd have to strongly agree that its all in the tune, fuel and oiling.
From the research I've done the SBE Gen IV LM7 I'm building outta live a very long time at 800whp which is the current goal.
If I can squeeze 800whp @ 7-7,500 rpm out of the little 7875 I'd be very happy.
