Recently turning in our 2008 Sparkling Graphite build, we took ownership of a new 2011 Alpine White M3 to begin our new build. Going the opposite direction of the previous M3, we choose very little options with one primary goal of building this into one hell of a beast.

Once returning back to the shop, work immediately began. With a collection of parts from the previous project, we carefully cleaned up the new parts and began the transfer of parts.

DAMN IT!!! this is the 50th eas thread i'm subscribed to now
congrats on this new project btw!! already of to a great start

although, i'm saddened to read ya'll turned in that sgm monster

[V8M3Bimmer]

Looks nice, let's see those AIB 4.0's turned on!

[crs2pepper]

subscribed - looking good Tom

[rjd598]

[mkPOTO]

subscribed, im hoping to upgrade to a 11 in a year or so.. so sick!

[Brucewonder]

cant wait to see what you guys have in store for her

[flipm3]

I'm excited to see this build progress. Hopefully we see some track photos soon!

Out of curiosity, is there any reason you chose the Duke Dynamics trunk instead of the Challenge?

Recaros are definitely in the near future. We need to make this car as light as possible.

We simply had the trunk left over from another project, luckily AW is the most popular color out there.

We have some plans for the Challenge pieces soon, we're waiting for the parts to arrive on their end.

Awesome! I really like the direction you are taking this one. Looking forward to what's in-store

Like that front lip!

[tightie]

lovin it.

Any interior shots?

[tom @ eas]

As there is a supercharger going on the M3 soon - we really wanted to see what power can be made with simple Bolt-Ons.

Items installed:
- Akrapovic Titanium Evolution Slip-On Exhaust System
- Akrapovic Delete-R Check Engine Light Suppressor
- Challenge Stainless Steel X-Pipe Race+ (Catless)
- Macht Schnell Stage 2 Intake Charge Kit w/ ICS Scoops
- Macht Schnell S65 Performance Underdrive Pulleys

The Macht Schnell S2 intake is a work of art. The rotomolded polyethylene pieces, silicone couplers and euro hose clamps give the system an OEM+ look with texturing matching the intake manifold.

The charge pipe is noticeably larger than the stock unit, eliminating the "accordion" type bend and restriction found on the stock unit. The included rubber couplers allow for proper engine movement. after installation, a noticeable intake "growl" can be heard from the engine compartment under acceleration.

The stock airbox is awesome in the M3, but there is definitely some room for improvement for those looking to modify.







Macht Schnell S65 Performance Underdrive Pulleys

Underdrive pulleys have been used on domestic for years, but the concept is still relatively new to the EU market.



Pulleys are a great way to gain HP, the concept is simple: Lower rotational mass frees up parasitic drag which normally robs HP. However, care must be taken in ensuring these safe levels are not exceeded.

There are two deciding factors in which I particularly liked on the MS pulley system:

- Two pulleys are provided (with most companies only providing one pulley), the power steering pulley allows the A/C compressor to retain its normal speed, not weakening - especially during hot summer months. The BMW system is designed to disengage the A/C clutch at WOT, which adds to the benefit of the 2-pulley system.
- Normal off-the-shelf belts are used. BMW uses a double-sided 6-rib belt system, which is not normally found in parts supply houses and can be quite expensive from the dealer. Included were name-brand Continential belts.

The Macht Schnell DualDrive design replaces the Crank Accessory & Power Steering Pulleys, reducing the power required to turn accessories. Some would even argue there is a slight increase in accessory lifespan.

Akrapovic/Challenge Race+ X-Pipe
As per the Akrapovic, what can be said that hasn't been said already? Full Ti construction, amazing build quality which is above any other.

Coupled to the Akrapovic system is the Challenge Race+ X-pipe, removing both the restrictive primary and secondary catalysts from the system - giving a throaty exhaust note. The Challenge X-Pipe was similar in weight to the Akrapovic's X-pipe, mostly due to the omission of the catalytic converters and resonators.

Akrapovic tip shot


Upon startup - it was immediately known this exhaust combo not for the faint of heart. The sound is awesome

Dyno Results
Baseline dyno shows a 345hp/254tq reading, which is about average for the S65 powerplant. With the pulley, Intake and Exhaust components installed, we saw a ~40hp gain, with an added bonus of shedding approx 50lbs from total weight.

While peak numbers are normally what is touted about for bragging rights, its important to take notice of the area under the curve as power can be seen throughout the entire power band.



While we're very satisfied with the results, the M3 feels better throughout the entire powerband, as well part-throttle driving.

A proper tune should be able to reach the 400hp club easily.

Impressive car. I really love the look. I own an AW M3 as well. I've been looking at the pulleys and I think for my car (08) I'll only use one replacement pulley. That's quite a gain for something so basic.

Kudos on the beautiful car.
