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.

crazycage

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.

creator

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

crazycage

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

jammerrs

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.

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.
