4k cash?

LOL, i wish man, but I just cant afford it.

GLWS though! and good luck in NASA

Based on my experience adding a catback exhaust, after market filter, or aftermarket pulley provides zero power gains I’ve been diligent with before and after dyno’s for each mod I've added and the RDSport Exhaust, Akra exhaust, AA pulley, and MS filter gave me no hp or tq benefit.

Other than a supercharger, the only bolt-on part that seems to guarantee power is cat removal.

Don't you Dinan guys have the associated tune?

[Powerbeast]

NIce line up.

tinpot doesn't have the Dinan car. The other Dinan car is ///M Ryder. And yes we both have the Dinan tune, hence no torque drop and HP climbs to 8400 rpm.

And yes xsilvor, you need to get the Dinan Mid-Pipe and rear section. I still need to give you a ride. Keep in mind, for some strange reason, the full Dinan setup sounds different in an E90 than E92. In the E90, it sounds more raw-like, growly, and raspy. In the E92, it sounds more refined and a smoother tone, but still pretty loud at WOT. Pay close attention in the two videos just before the E92 and E90 go WOT on the dyno. You can hear the difference.

For both E90 and E92, at cruising speeds (non-WOT), both cars sounds like they only have the Dinan mufflers--which sounds almost like stock. So in a nutshell, the full Dinan system can be quiet if you want it to, or extremely loud if you want it to.

looked like a good time! thx for sharing

[IFX]

thanks for sharing.. question:

How does one determine which gear is best for putting down the most power?

[teebo2345]

So the lesson learned is don't do performance mods on the e9x platform. I am actually very surprised at the results....

[frankzlin79]

You can do performance mods on the E9X M3, just be expecting to spend a whole lot of money for minimal gains (less than 30 whp). If you want the best bang for our buck, the only thing you need is a cat-less mid-pipe and a tune.

If you want serious gains, then forced induction is the only way to go, but by then, we're talking about spending a whole bunch of money.

Of course, the correction factor used is also very important. STD corrected numbers can be 10 or more whp higher than SAE corrected numbers. A lot of people post the STD numbers. Some people will do worst and just post a number, without stating the correction factor used (if any) or just post the uncorrected number. My car was making 379 whp at 51 deg F and 40% humidity using uncorrected numbers.

I wish I got the print-out for the STD corrected numbers to compare with my SAE corrected numbers, but I forgot.

Very interesting Dyno run for first car on the list.
Seems like you guys had a blast and def some nice rides !

[flipm3]

Thanks for sharing the results. What I'd be most interested though is to see how these cars compare on the streets. What I've been seeing lately dynoing my own cars and seeing others, is that despite our power variances, sometimes they perform the same or even "underpowered" cars perform better.

I could be wrong, but I feel like dynoing these cars and comparing to other fellow M3s can be pretty difficult and should always be taken with a grain of salt.

Either way, it looks like you all have well powered NA M3s! A definite good group cars over there

[Gkap]

looks like you guys had a great time

2008 M3 E92 - DCT
Stock
334 whp
246 ft-lbs

vs

2009 M3 E90 - 6MT
Performance Mods:
Turner Test Pipe
Evolve Software Tune
Active Autowerke Green Filter
340 whp

so primary cat delete + tune only yields 6 whp increase??

maybe the way both cars are driven could sway the results?

Unfortunately, it's rather hard to say. More likely, the two modifications are worth a lot more than 6whp. It's difficult to compare two vehicles simply due to many variables (wheels, tires, fuel, adaptations, IATs, etc). Simply looking at the DynoDatabase and seeing the HUGE range in power these cars produce stock prove that.

It would be a lot more beneficial if the individuals with bolt-ons and tunes had baselines from their own vehicles on the dyno and other performance data to truly gauge the benefits of their respective modifications.

Thanks for doing this for us! But can you make some corrections so that credit is given...According to the database, you have frankzlin79 as claiming to be the owner of all 4 of those M3s. The owners are as follows:

2008 M3 E92 - DCT (rlzhao)

2009 M3 E90 - 6MT (KennyPowers)

2011 M3 E92 - DCT (///M Ryder)

2010 M3 E90 - DCT (frankzlin79)

Exactly. But none of us had stock baselines to compare with. Doh.

But tinpot has done multiple dynos as he was modifying. When his car (before he got ESS S/C) was close to similar modifications as ///M Ryder and mine, I believe that he said he was making around 350 whp, too.

[frankzlin79]

I really qustion some of the entires in this database. Like this E92 6MT with only an Eissenmann Race exhaust making 370 whp (SAE Corrected)....

This is kind of the point I was trying to get across in my former posts in this thread. Unfortunately, it is just so hard to compare due to the huge variance in power. It is well known that IATs and Fuel make a HUGE difference on this car.

I can almost guarantee that the specific car that put down 370whp SAE will run probably no quicker on the straight away compared to Richards 334whp SAE.

If my assumptions are wrong, please correct me.

[frankzlin79]

The problem is also that dynos across the country may not be calibrated correctly or have lost calibration over time (and the shop owners don't realize it). Thus, some HP and TQ numbers may be skewed to high or too low. The only way to compare different M3s power is to have them all make runs on the same exact dyno.

With that said, everybody on the forum should drive to Houston for a super dyno day!

Are you suggesting a 4-way drag race on the highway?
