Default Lightning Con Rods

Has anyone got any feedback on Lightning aluminium Connecting Rods
Is the extra $300 - $500 worth paying for GRP's or BME's

Application is a pro style door car 2200lb, 1000hp single carb on racing fuel

Any feedback greatly appreciated

Regards

Warren

Big reason for running aluminum rods is to NOT beat the bearings out when running Nitrous or blown applications..the aluminum rods cushion the impact on bearings...it is also suggested that aluminum rods be changed out around 50 passes no more than 75/100 passes.

If I were you I would run a good steel rod in natural aspirated motor.. Much longer life !

Good advice
We are monitoring a minor crack on the number 3 main, would the slightly heavier rod adversely affect the crack?
Block is a stage 3 KB
Crank is a winberg, crack is small, crank too good to toss

What steel rod would you suggest?

Thanks for your help

Was the crack found after magnaflux or human eye..also can it be fixed ?

Yes rotating weight will effect any crack..hard to say from my end how much..I probably wouldn't try to compensate for the crack with a lighter rod that will need to be replaced often. You are not guaranteed the aluminum rod will add any extra life to the crank...but to answer your question on steel rod. PAR uses manley 4340 on some of his 1000 hp stuff I have used Callies same 1000 HP engines...

Crack was found by magnaflux and repaired
By the sounds of it i would be better to stick to the plan of using alloy rods

My intention is to replace the crank after 50 passes
