Acerbus 2.0

Well that was a bit of a letdown...
401rwhp, 365rwtq redline.
10.4 A/F readings at the tailpipe. I could literally see the fuel gauge go down as the rpm gauge went up. HA!
I was hoping for 420-440.

I'll try to get this dyno sheet digitalized, so I can send it to Brenspeed. See what can be done.

Not bad..... refine the tune and you should be where you want. Good luck!!

??? Mudflap was making 415whp on his non-intercooled V3


No worries about the numbers, you have it all dialed in with plenty of fuel as well as an intercooler. At least you don't have to worry about your motor, just as long as you drive like a human being lulz

Hmm, was that a DynoJet or a Mustang dyno? I would expect that kit to put down at least 450rwhp, and probably closer to 480+ with your mods.

Its funny you mention the driving conservatively thing... back before I got the Vortech on mine, I drove it like crap, lol. WOT all the time and burnouts and crap. Then I got the blower put on, and I was afraid it would explode so I drove like a grandma. That is a huge contributing factor to why I've given up on the idea of supercharging this one. Its pretty quick now, and I have my foot in it constantly. I'll just stick with what I've got, lol.

I do recall asking Brenspeed to tune conservatively due to shoddy puertorican gasoline. Also, you have to remember my car is an auto (for shame, I know). A lot of power is lost there. And finally, during these dyno runs, temp was at 87°F, 46% humidity, and the dyno operators forgot to put a fan in front of the intercooler.

I seriously don't mind these low numbers. They are enough to make stomping the gas at 30mph a tail happy experience. What I do mind is that fuel mixture. It may be "safe" for the engine and tranny, but I know I'm not doing my O² sensors, and spark plugs any favors. I already contacted Brenspeed about it, hopefully they'll get back to me on monday with an answer.

400whp feels like a lot doesn't it?

Makes you think about how people are saying the M90 is "only" capable of 450whp, when a lot of people haven't even driven a true 450whp car before lol

Any pics of the Paxton?

Nothing wrong with the auto my friend, my 07 and this 2010 are autos. I like them both way better than the manual 09 even with the supercharger.

From Brenspeed's website, this kit is suppose to put down 190+ RWHP? And with your mods it should even be higher.

How do you find the power on the car below 4000RPM?

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!

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!
