Motordyne M370 installed.

UTAMAV

I had the Motordyne Plenum installed today at Scarab Performance in Mansfield, TX. As always, thanks to Dan for doing quality work on a car that deserves it. Onto the install.....It is definitely bigger as it sits higher than the stock box, and the mods seem to be on the inside of the air box. Also to note, Motordyne is not using, or seems to not be using the stock Plenum for this mod, their box is slightly different than the OEM box. So here we go, just a few notes about the install....

1. There is a vacuum hose that runs from the back of the box to the front.....I should have snapped a picture but it was too short to run under the throttle body. We had to place it on top and hide it with the engine cover.

2. Also, there is an intake baffle on the right hand side of the car that will not bolt back on the the plenum. The bolt holes are not the same as OEM for intake baffles. It just kinda hangs there, a simple hose mod will fix the issue. Maybe Motordyne will consider this too.

Gains: I decided to let the ECU make fine adjustments for about a week before we take it back to the same mustang dyno. Also, I am trying to find a day that had about the same temperatures, air quality, blah blah, etc....I will dyno her next Tuesday or Friday to see what we get. I will post on this same thread my original dyno and the post motordyne install dyno.

Butt Dyno: I think I have gained around what is to be expected 15-20whp. You definitely feel the difference and it seems to pull harder and faster to redline. I did a 2nd gear "pull" at 4000rpm to get around a slow farm truck on the way home and broke her loose (TCS on). I definitely think, just by the feel of it....this mod was surely worth the bones I spend on it.
