im curious if i should upgrade to an aftermarket crank or not. Is there a certain point in which it would be a good idea to upgrade to a forged crank???

 

no.... stock is fine

 

the stock crank is sufficient for anything that you can run on the street, unless you want a stroker, or lower inertia in the bottom end

 

i dont think Ive ever heard about a broken crank before. that is def not a weak point.

 

what are you 700whp guys using????

 

The stock crank is a forged steel crank.

The only broken crank I've ever seen is from a turbo Prelude that had a knife-edged crank. I don't think the knife-edging and subsequent balancing were properly done.

Stock. We dont drive Neons (SRT4s).

 

i have broken the oil pump 3 times that runs off the crank. that seems to be weak. but never broke a crank.

 

holy crap, that neon was owned. I bet that ruined the owners day, big time

 

damn i guess they can take a beating then Im just trying to avoid a catastrophe ...i knew it couldnt hurt to ask

 

my buddy bent a ls crank on a 190 whp lsvtec..I think it was a fluke and the crank was already weak from other issues.

ooooooo, this was that neon. I heard about that but never got to see all of the pics. i'm glad he walked away. I wonder what that sounded like, must have been un-real

I am not sure they even know. but it sure does scare the crap out of you when you see it.

 

oem cranks can hold about 500 hp. after that you're in gods hands.

and yah oem is also forged and balanced pretty well from the factory.

personally i wouldnt knife edge the crank. a light flywheel will do the same without weakening the crank.

EDIT: tuning as with everthing, plays a major role. and yah i mean honda cranks

 

Woopsy!

yeah for sure the oem crank shaft is good. it can handle up to 600whp, my friends delsol ran a 11.50 in his old motor (fully built b16 turbo) (over-rev) and he has a stock crank, and his new motor, that will be way faster then is old one, he's using a stock crank.
