Thread: Xcessive Plenum for N1 intake runners

I will be receiving the Xcessive prototype/production plenum to test fit and photograph next week. I will then be able to quote pricing and the various options.

OK, here are the pics and the pricing.

Pricing is tentatively set at $375 for N1 Plenum kit. Includes 1" base (production piece will be black) with velocity stacks, plenum and hardware. This doesn't have a provision for the IACV, so you'll need to get the relocation kit. Velocity stacks could be cut down and made slightly shorter if requested. There are optional throttle body paterns that can be done as well. The one pictured is set up for a Q45 throttle body. Q45 TB with TPS is an additional $125 if needed. These plenums are always reversible for RWD applications.

Also, $375 is the price with the Q45 TB flange. If you want an N1 Flange that will be an additional $80. If we have some demand, like 3 right away, we can do them for $25 each.

In there...you da man, as always, gregv!

- Thank goodness!

This will be interesting. What is it going to consist of, a base with stacks and planum? I hope this actually make some power!

Greg stick with reg ve runners. its been proven n1 i/m's provide zero gains.

Stratton.

And for people who want an option to utilize the 8 injectors?

In stock form this is somewhat true but we are not using the entire N1 manifold. Only the primaries.

The current xcessive bolt on kit is way too short as the stock primaries are much shorter. This kit will allow longer runners with a much larger plenum.

The only problem I see is not being able to utilize a decent stack up top. The N1 taper is tiny up top, killing the ability to fit stacks properly on runners 2 & 3. They are very close together.

Well, there are certainly application where an N1 mani will make more power than a std VE mani. And this plenum will lengthen the runners significantly. It will have a 1 inch spacer, + velocity stacks inside the plenum. It's in transit and I will post pics when here. I just have to test fit it and then there are already a few guys waiting.

We're going to see how he did on that...
