I will be intalling an Offy intake on my van soon, and came across an interesting product by Offy:



This is supposed to be a bolt-on cross-ram simulator. I want to try this on my van since I can't run a hyper-pak. Do you think it will actually help create a ram effect if I mount it so that the carb sits over towards the passenger side of the van?

No idea, but I would run it just because!

Is it expensive?

It costs about $140 as pictured.

Wow, what a bizarre product! Is it new, or another old treasure that Offy's had catalogued forever? What's the Offy P/N?

(If I had one of these, I'd probably be completely perverse and use it with a 2bbl adaptor plate! )

What HE said!!!

Only I'd get it backwards!

Actually, that is exactly what I am going to do! I will be running a BBD first, but eventually I am going to run a staged Holley 2305.

These are being sold new through a website:

It is four inches tall and 13 inches long, which would rule it out for a normal car application (unless you didn't have a hood), but it will fit fine under the doghouse in a van!

I thought you had a hyperpac?

It wouldn't fit in the van, so he sold it to me a while back...it currently is at CPM being machined for an EFI setup...

-D.Idiot

I can't see how it would work extending the runners into a ram effect........

It's a big open volume (offset to look cool), so all it would do is increase plenum volume.................

Plus you're doing 2 more 90 degree turns of the air flow, that can't be good............

So the 90 degree bends will hurt airflow and the ram effect won't happen due to the open area?

I thought that the ram effect simply had to do with the volume of air moving into the cylinder due to inertia. I don't know much about intake manifold design, so any comments would be appreciated.

Exactly.
