There are two big things keeping us from doing dynos . . .we have no more stock cars and us posting dynos just causes arguments. In testing Doug’s car for the new heads and cams he is working on, he also exchanged plenums to a new cast piece. There have only been improvements in numbers since the switch. Now because other things have changed as well, there is no reason to believe any difference in performance is due to the plenum.
Like we have said the design is the exact same as the current plenum, the mold was made exactly from it. Expect similar performance gains.
Some of the main reasons the cast piece was made, was to eliminate much of the fabrication hours and to offer a plenum not requiring a core. This keeps costs down on both sides and makes it possible to pass the savings on.
If you look at the price, currently a black plenum shipped with core shipping back costs somewhere around $450 depending on shipping costs. Right now Doug will be selling them for $350 plus shipping.

HERE ARE THE PERTINENT FACTS REGARDING OUR NEW PLENUM:
__________________________________________________
What is the advantage of the Crawford intake plenum over the stock plenum used on the Nissan 350Z and Infiniti G35 and FX35?
The stock plenum, due to the slope towards the front, which Nissan designed to clear the stock strut bar on the 350Z, restricts the airflow to the front cylinders. Our design raises the front of the plenum as shown in the picture below, allowing more surface area and greater, equalized airflow to all cylinders. Greater airflow equals more power. On average, our plenum produces an increase of 9 hp at the original peak, and a solid 17-20 hp at redline.
__________________________________________________
What is the difference between this new cast plenum and the one we have offered for the last two years?
This is a solid, one-piece cast aluminum piece, not a reconfigured, welded stock plenum. The basic design is identical to our earlier versions. The advantages are that we do not require you to send in your original plenum as a core to be rebuilt, so you can keep it without a core charge. This plenum, like our earlier versions, will work with both normally aspirated and forced induction (turbo or supercharged) cars, due to the inherent strength of the all aluminum construction. Plus, it is a simple bolt-on modification that anyone can install with basic hand tools, generally in well under one hour.
_________________________________________________
What type finish is available?
All plenums will be powder coated with a black "crinkle" finish as shown below.
_________________________________________________
Can I use my factory 350Z front strut bar with this plenum?
No, it will not clear the front of the plenum due to the increased height. However, we do offer our own strut bar that fits in front of the plenum for $150 plus shipping. It is a straight aluminum rod connected by adjustable heim joints to powdercoated steel flanges and it comes with all hardware required for a simple bolt-on installation. Our tests indicate greater strength than the factory bar due to the fact that the factory bar is not straight (it is "pre-bent"). See picture below for an installed front bar.
NOTE: Strut bar will NOT fit the G35 or FX35, neither of which come with a stock bar.
Strut Bar Price: $150 plus shipping
__________________________________________________
Can I use my stock, plastic engine cover with your plenum?
Yes, with some cutting, it can be used. Many have used a Dremel tool to cut the cover to fit.
________________________________________________
When will the cast plenum be available, and what will it cost?
We expect to have the inventory on-hand to begin shipping these no later than mid to late February 2005.
We will be taking names to put on our list on a first-come, first-shipped basis.
We will not charge your credit card until your plenum is shipped to you.
The introductory price will be $350 plus shipping.
(Shipping costs generally are less than $20 in the U.S. for 3-5 day UPS Ground Service).
