First off, I want to thank Tony and Motordyne for everything they did to get the manifold out to me in a timely manner. I was fortunate enough to get it shipped from California to Maryland within 3 days.
Now, onto the good stuff! I wanted to personally see this manifold in action and see what the gains were going to be for my current mod list (Fast Intentions exhaust, Fast Intention Res Test Pipes, Stillen G3 Intakes, and Motordyne's Manifold). I had a custom UpRev tune from the get-go from a couple months prior, so I figured the gains were minimal in the beginning, but I still wanted to bite the bullet and see what the capabilities of this plenum were.
Broken down are multiple sheets to give you an idea of what type of gains were seen before we started tuning the vehicle and after (now remember, the car came in with a custom tune already).
This first sheet describes the Horsepower / Torque gains through 4 different runs. Runfile 001, 002 are both baseline pulls when we slapped the car on the dyno to see what it put down in comparison to after the plenum was installed.
Runfile 001 - Baseline
Runfile 002 - Baseline
Runfile 010 - Motordyne M370 w/ 12.8 Air/Fuel ratio
Runfile 011 -Motordyne M370 w/ 13.0 Air/Fuel ratio
The car seems to really like the extra fuel. We gained an extra 2whp just making the minor change of adding fuel closer to redline to get the car as close to top-end as possible. With comparing run 002, and 010 the gains were pretty good. We saw positives gains all throughout the powerband except for 7400 - redline (lost 1 - 2whp, no biggie).
From 4500 - 5500 - there were gains of 12whp, and 12ft-lbs of torque
From 5500 - 6200 4whp and 6ft-lbs
From 6300 - 6900 6whp and 7 ft-lbs
The rest were minimal gains with a minor loss at redline. The car had a pretty good amount of heatsoak since were making consistent runs to change minor things like timing and fuel so the torque would have been even higher if we let the car cool down for 15 minutes (it was getting late).
Here are run graph comparisons that Tony was ever so kind to export:
We didn't really do consistent runs at the end because it was getting late, so I didn't have the time to let the ECU fully adjust to the new fuel curves. I can tell you though that my butt dyno feels the kick, I know for a fact that isn't a placebo effect either.
All in all I'm really happy with the outcome. I'm glad it made more power over-top my other mods and tune. I would definitely buy this all over again!
