Stock GT Mani vs F150 Mani Dyno

So I finally got around to the Dyno with the F150 manifold and it seems the F150 beats stock all the way up to 6Kish RPM.


The Red line is stock
The Blue line is PP2 with Stock Mani & Catback
The Green line is PP2 with F150 Mani & Catback

[IMG][/IMG]

Next up is my Rob's tune vs PP2. Let me know if you notice a difference...

Red line is PP2 Parts w/ Tune with F150 Mani & Catback
Blue line is PP2 Parts w/Rob's tune with F150 Mani & Catback

[IMG][/IMG]

On the dyno Rob's Tune bog/studdered at low RPM. The log also showed close to 2* of knock @ 7k rpm. Wasn't exactly ecstatic...

Eh not sure why as it shows for me. I tried 3 different computers, logged on and off mustang6g & wifi, and still can see the pictures. I repasted the links let me know if you still can't see the pictures.

The four second video was just to show the car bogging etc. I can upload the full length but I dont catch the dyno numbers in the video but can upload it later.

I can see the graphs, the up and down of the torque is very odd..

Wow, impressive results. Very nice!

How does it feel driving? Can you notice those bumps in torque up and down?

Yeah the Hp curve is sort of similiar although there isnt as big enough drops. I wish there was a way to fatten up that curve between 4-4.5k rpm.

Not really, then again I don't spend much time up there to really notice a difference.

Update:
I updated the first post to show the full dyno run and included the 4th gear logs for Rob's tune

I see it now :-)

Looks like a 12hp loss for a 20tq gain at peaks. Almost 35 tq at one point in the band?

Nice gains under the curve but after 5000 RPM your stock manifold results look...weird. The HP flatlines and then rapidly shoots up almost like you had knock. Looked at some other dyno results and actually I guess that flat line and then the ramp up is normal. Man, I'm really excited to see if the 2018 manifold offers an inexpensive version of the GT350 as these cars really look like they just need to rev to 7500 to make good power.

So a PP2 makes more power than Rob's custom tune?

Something seems wrong with the car, as if the manifold "charge motion" valves aren't working properly. Is the PP2 Ford's tune?

PP2 with the GT manifold and the F150 manifold look identical up to 3,500RPM, then some weird stuff happens with aggressive torque dips and spikes from 3,500-5,250RPM. There's a pretty extreme torque dropout at 3,700RPM and a horrible aggresive power increase at 6,300RPM.

For the F150 manifold, the aggressive torque spikes at 3,700 & 4,700RPM must have a pretty noticeable "surge" to it. Hell, I can feel the stock torque surges between 3,500-5,500RPM, I can't imagine how unrefined and bad that curve would feel. That's one thing I miss about the extremely flat torque curve of my S65 BMW M3.

What other mods have you done to your car?

Would have been nice to see the pulls start at a lower RPM, like 2,000RPM.
