That would be awesome! I'm looking for one that exits on >>>> this side. This could be very interesting if your mani runners bolt to it.

That's what Blackheart is saying. $400. He's local. ATS Diesel. It's right down the street from my office. I'm going to stop by there.

And... they are reversable

You could do the same thing with an NA mani. Buy a dplenum from Ross Machine, end caps and q45 TB...and bingo...cheap, big plenum intake mani and TB setup. Less than $250 in parts, including TB. I have an NA mani on the shelf for this purpose

Hope to test short runner vs long runner (both with bigger plenum and TB) in the future on my setup.

Hell I have an NA mani laying around too. I wonder if we've gotten an aluminum welder yet...

Here is the xcessive "velocity stack" design. Same as NA mani with an added plate to smooth the transition.

Worth every penny! (hint: if you make them an offer, they'll go much lower)

Erron, did you do any before and after dynos? If not, butt dyno gains and at what rpm range?

**Erron Spalsbury** · 03-13-2012, 12:26 PM

I changed a few things when I installed it so no real valid numbers.

Butt dyno, it's mostly in the top end. Seemed to help spool a tiny bit but the top end seem to have the biggest impact.
