Connecting rods Got a question for you boosted gents. I was wondering if compstar connecting rods would be reliable for a low boost, low rpm build. I'm looking at about 1k hp, but I am only looking at about 10Lbs and 6500rpm. I'm hoping cam selection will allow 1k hp with that rpm and boost level on 438 ci. So, that being said , will those budget rods be reliable if my max rpm is 6500 ? Thanks.

what ive seen is hp rating for the overseas rods depends on rod bolts. 8740 bolts usually 650 to 750hp. 2000 rod bolts usually 1200hp and l19 rod bolts 1500hp. The rod is the same in each application just rod bolt difference.

The rod bolt gets beat on with a tension load... That load trying to rip the rod off the crank as the piston nears TDC, especially on the exhaust stroke... A product of rpm
We carry alot more residual cylinder pressure to oppose this compare to anything else
The compressive load from TQ is the rod killer for these
That is a ~618g rod
Take a gen 4 rod ~645

Molnar power adder plus, Callie's enforcer, Oliver speedway are all over 700g
