Paxton NOVI2200 first impressions, thoughts, and a question
#21
For me, even with 4.10s and the Vortech with an automatic- it really wasn't all that great.. but WOW, once I floor it and the kick-down engages.. it's a whole different animal. Yes, with only the 380ish whp I had at the time.
By far, the BEST mod I have done to my Mustang but the other mods compliment it great (4.10s, delete plates, cut outs)
I have decided to keep my kit, and boost the hell out of it!

Maybe with an auto, you are not getting quite the response from the Vortech you would get with a 5 spd manual?

I received a prompt reply from Brenspeed, as expected.
They need my dyno graph to be SAE corrected and not STD. Also, the dyno was measured in mph and not rpm's so I'll need to find a dyno that does that. I also think Brenspeed suspects the same thing I did, I ran that dyno with a normal street tune. I think the car downshifted to third on the runs, and therefore the low numbers. They'll send me a "dyno tune" as soon as I can find a shop that does the diagnostics they need.
I didn't think Brenspeed would provide remote tuning like other online tuning shops. Nothing but topnotch service from those guys. Class act!

If you're looking for an instant punch of tire shredding power from a dead stop, a centrifugal kit isn't the right choice. I do believe however, that its easier on the engine and tranny than a roots or twin screw. Brenspeed has also told me they agree with this as well.

What I meant earlier about a "dyno" tune was just the same tune I currently have, same timings and everything, but with the auto trans set up so that once it reaches 4th, it doesn't shift back to 3rd when you step on it; allowing a more accurate dyno reading. Sorry if I confused anyone.

I wouldn't say unhappy.
In D, by nature, the autos RPM will rise and drop with the press of the throttle. With a manual, the RPMs are more responsive and more power gets to the wheels. The auto HAS to kick-down to get that power band kick in order to really accelerate. With the 4.10s, it's nearly instant when I floor it, and going from 0 boost to 8 psi (basically idle to 3k rpm/BOOST!) it takes off like a rocket! Pretty much like a light switch, "on/off", "min/max".. there's no real in-between. Again, this is with the 4.10s. I'd imagine 3.31s or 3.55s would be more of a balance.
But you're right about day to day driving with it on D and just putting around.. you'd wonder where all your power went lol.

I managed to run the car again in a different dyno shop that measured in rpm's. Almost exact same results; 405rwhp 354rwtq. Same sub 10's A/F readings at the tail. This time around I was trying to get the car to stay in fourth but it was just impossible. It always shifted back into 3rd.
So that means my car has 400freakinrwhp in 3rd gear! I believe that's plenty for me.
I sent the new graphs to Brenspeed. Hopefully he can use those to make any corrections needed to the tuning.

New numbers are in: 434rwhp 390rwtq using the dynolock tune Brenspeed sent me. Now we're talking! A/F ratio still in the 10's.
I already sent Brenspeed the new graphs. I'll let you know what they can come up with. The ball is in their court now.
