Hi,

Just wanting to know whats the limit on these as in power etc? not wanting random comments, i want peoples honest opinions or whoever has these fitted and what power they are running.

 

i wouldnt want to run them on any engine over 250hp ,people will say they run them at higher power out puts but i wouldnt.

 

totally agree with crazycage i ran mine at about 250ish bhp only for about a week and had a word with karl n oli and they rekond about 250-270bhp max to be safe

 

300bhp, no sweat.
seriously ian howell used to run them to that power on his early zvh/zt builds.
i'm running about the 300bhp marker on my zvh on standard rods (i'm on same spec as a guy running 318bhp), just don't be redlining them though, that's a beauty of a zvh, no point reving much over 6krpm.

 

Does he still run them at that? if not why not? just woundering thats all

 

its only about £250 for a set or steel rods thats why lol.

 

270 imo

 

more than likely that is the case.
all i can say is that i'm running 21psi through my zvh and it's still running fine on standard rods, but as with a zvh you don't benefit from revving really hard.
personally if i were to build another engine, then i'd be fitting steel H setion rods for piece of mind.

 

ian howell will only gaurantee standard rods with arp bolts fitted upto 260 bhp , but has told me on many occassions that they are safe upto 280 bhp , then he recomends steel rods.

cheers paul

 

Shaun (Turboboss) off here with the massive spec ZVH told me he ran standard rods at 330bhp for awhile.

But as stated by Crazycage - steel rods are cheap as fuck now, especially considering they come with £50 worth of ARPs.
