Get out those old decoder glasses.

I'm not willing to say how I obtained this, nor will I reveal my sources, but I found their preliminary dyno test results on the manifold. @NotEric6 sorry to be the leak, but I couldn't hold this back any longer.

Oh man!!! Now that we got results, when does the preorder start?!

Yup that looks about right

A man can dream right?

Three more photos:

Bellhorns should be here today, I hope.

That looks stunning!

NotEric6: I sometimes wonder if angling/splitting on other side wouldn't be better/straighter for airflow. As in - shorten intake tube, so that common tube fits and can split in front of cylinders, so that airflow is turned only 45deg, not as of now, when it's split/turned 145deg. Think of mounting this manifold backwards with splitter re-welded other way around. May cause fitment issues .. but intake manifold plastic tube should be easy to shorten, no?

I would guess it wouldn't fit or you would need a custom intake. Look at where the throttle body is in relation to the front cylinders, if you rotated and placed the throttle body where you suggest it would stick much further forward. Surely a better idea would be for the chamber intakes to be more central, but then again I'm not very clued up in fluid dynamics.

Custom? Yes. But as i see load of aftermarket intake tubes for $100, it should be easy to sawn off from some to fit or design own of needed length at similar price level. Much cheaper/simpler, then main manifold metallic part design/manufacture.

It probably has more to do with the volume of air than how straight the path is. The airflow will have to make a quick right angle turn anyways to go down the horns, so it doesn't really matter which direction the right angle comes from.

Exactly, volume of the plenum is critically important.

For OFT users can we have shiv all over this please!?!?!?!?!?!

First it needs to be finished...

Shiv has said he'll tune anything given access (and time) to do so... That said, at this level of investment I'd expect you want a custom tune...

VerusEric · 05-18-2015, 02:45 PM

We are still waiting on 2 other bellhorn heights to come in but progress is progress.
