A day that turned into a week, on the flow bench.

Tom from Driven Innovations contacted me and wanted me to try a new idea/intake manifold he had built for the EVO. I told him I'd be glad to try it.
Yesterday the intake manifold arrived at the shop and I got it installed on the car immediately. Fitment is excellent. The intake has large re-enforcements welded on to the fuel rail stands. It also has provisions for the dipstick mount. The intake has a small plenum on it, 225 cubic inches. The upper i/c pipe goes right on with no modifications of any sort needed. The intake is flanged for the stock sized (65mm) throttle body and will not accept a larger throttle body. The plenum has raised velocity stacks in it with a 6.5" runner length. There is a thick block on the back of the intake manifold for the vacuum lines to be run to. I installed only one line and then ran that single line to a Vibrant vacuum block to make swapping intake manifolds easier.
I prefer to run the stock modified throttle body, I like the idle control, the fitment and the feel of the throttle.
Here is a picture of the intake manifold on my RS:
On the dyno I was happy, extremely happy actually.
Here is the best curve I have had to date with my car, this is with the custom intake manifold we built. This run was done at two boost levels. The first one the boost hit almost 32 psi. I turned the boost down and the boost was right at 29 even. The baseline was done at 30.7 psi. The solid line is the custom intake we built VS the new Driven Innovations intake:
Here is the best curve at high boost, 40 psi, with our custom intake manifold VS the Driven Innovations:

It truly is an amazing accomplishment… Tom and DI came out on Top of the Intake Development on There first Appearance on “Bad Bish” V2 and continues to do so. Congrats, DI FTW!!
