Well they were added yesterday and the Series I crowd doesn't frequent ZZP or INTENSE much.

Anywho... cheaper than the 1.72 Yella Terras DrJay got us from Australia.

Looks very intersting. I assume their claims of 20hp are on supercharged applications, I wonder that would translate for those of us who are N/A?

well you aren't making any changes to duration.... just lift... But...

with these rockers... iirc.. Your intake lift will go from .400 to .450 and you exahust will go from .408 to .459

I'm not so sure we'll get much of a gain for the N/A... I'd like to see some dynos for both NA and SC, it would be really interesting and a great advertisement. I'd get it right away if it went upwards of 10HP.

Anybody have close ties with ZZP that could convince them to show some real results like dyno charts and concrete numbers. I too would jump in if there was a decent gain around 10 HP and I didn't have to change any other internals.

ZZP is REALLY busy right now... Even if they were not busy you would prob. never see a dyno. The profit ZZP will make from these will not even justify him doing a dyno - that is where we come in.

They are coming out with a ton of new products and setting up their new shop. Also they are knocking on the doorsteps of 8'* in their TTGT and shooting for 500 WHP with a M90 and 300WHP N/A.

20HP? Maybe? Maybe not? I do know that these will allow you to reduce KR - if no KR lower pulley size and help power in the upper RPM that a series 1 could really use. From that you will gain HP - how much? That is for us to find out...

I'm going to seriously consider these bad boys. $350 for 20 hp seems pretty cost effective. 20 is probably for a */c motor. I wonder how much you could get N/A...?

This winter, with a new timing set, those '95 heads swapped in, and these rockers...I'll be in business

Wouldn't a vendor like ZZP already HAVE dyno numbers if they advertised a claim like that? I would assume it would be a very simple matter to ask ZZP for the dyno data and get it. Are you speaking for ZZP officially, or do you not believe they have the data?

My suggestion to any member here would be to contact ZZP in the interests of this topic, get the data, and post it for the benefit of those interested. After all, this is the bulk of the Series 1 L67 market.
