Dyno for stock 1M with MadDad's

So how much is the gain HP over stock ?

247.7 kw = 336.78 hp which should be a minimum 370 hp at the crank (10 % loss).

Like Denso asked how much is the gain and do you have stock vs. MD installed torque numbers as well?

Could you also comment is there a noticable improvement in throttle response, especially if you are not on M mode?

How about the upper regime, 5500 to 7000, did you notice improvement there?

Sorry too many questions but you seem to have one of the few who put the MD on an otherwise stock 1M.

The noise in your video is perfect for me, for sure there is some hp and torque gains too which is welcome. But what I want to really "tune" is the drone just a bit down (mine is quite loud in between 2000 to almost 3000) and have a better/quicker responding throttle in non-M mode.

I also had the "drone" from 2200-3000 that was driving me up the wall. I installed the N55 midpipe [with no other changes] in Feb. It made a BIG difference in mine. I would say it took care of about 80% of the problem. It is pretty well gone [ie --very low between 2000 and 2750 rpm's]. Between 2750 and 3000 there is still drone under light load, but the sound is different, and "better" [ie-- more like a power sound]. I "think" it feels like more power is there [but that may be just wanting it!] The sound is better for sure. Overall I am very satified with the change .

.. PS: love your Country-- was there two years ago for three weeks.

Other than the reduced drone how would you describe the sound:
1. on startup
2. throughout the RPM range
3. on throttle
4. lifting off the gas

Thanks!

Didn't dyno stock. expect 8HP at the wheels and improved throttle response.

Gains between Berk/N55/MadDad's are probably all similar, choice comes down to the sound you want.

Thanks for the input, I appreciate.

If you mean Chile, I am not Chilean, am an expat living here, a diplomat. But lovely country anyway.

Regarding the sound changes, I would say that with the N55 it is a little louder on startup and throughout the RPM range when on light throttle. there is more change when on heavy throttle... don't remember difference when lifting. Overall it IS louder, but not a LOT-- no Major changes.
.......... I guess the best test is that the wife had commented on the less drone, and has NOT commented on it being louder [..but I am NOT doing heavy throttle with her in the car]

In for the GB

4thM3 · 04-11-2012, 08:59 PM

I'm also intested in GB

Having a hard time deciding on replacing the mid pipe or get new exhaust. Stock is just a little too quite. Thinking about Borla exhaust. Sounds pretty darn nice.

Interesting this long delay. Maybe they don't have enough in stock and not answering is a way of answering

it's not like them, at least from when I dealt with them (Rich @ MadDad). I was actually the test mule for their first prototype back when they came out with the mids for the 135i and always had immediate response from Rich and team.

Just a thought here...

why not just go to a muffler shop and have them pipe out the mid-pipe cats on the car and / or have them chop the resonator on the mid-pipe and pipe that out too?

It would be a LOT cheaper and performance over spending 700 on just a mid-pipe cant be much more I would think...
