Thread: HV3 insert installation help

DIY HV3.

But that doesn't count because I don't think it does a damn thing.

It probably fell apart inside there anyways.

you can see the hv3 make more power after 4800rpms. and doesnt fall on its face as much after 5500 rpms.

Still falls pretty hard.

Needs headers and valvetrain mods.

But for a piece you just toss in, it does help. Mine worked great when I had it.

^^ that it does, regret getting it installed before rockers and headers lol
