Project Frozen Gray M5

This thread highlights some of the most recent modifications and experiences with our F10 M5 Project car.

To start here are a couple photo's of our Euro delivery of the new Turner M5 project car. The car is now back in the states and we have begun to line up some products for the car. We are also doing some R&D on the car to come up with a line of performance products to improve the car in some areas such as braking.

At Turner we pride ourselves on being on the cutting edge of performance and technology for BMWs. We want to have a complete understanding of these new cars to secure our future as a leading BMW tuner. Please stay tuned for more to come on the new M5. Our goal is to take this fifth generation M5 and make it unique. We are going to hand pick the best possible products and accessories for this project car to learn first hand the true potential of this latest generation of forced induction BMW power plants. Please stay tuned as we begin to modify this M5 and review the products we use.

The Gruppe M Cold Air Intake for F10 M5

The Install:

The Gruppe Intake for F10 M5 fitment is very good. The install takes approximately 2-3 hours depending on skill level, this includes the removal of the front bumper. We followed the instructions which were good but were sometimes hard to follow due to the translation from Japanese to English. We began the install by removing the front bumper of our M5, this was relatively easy. The most difficult part of removing the front bumper on our particular car was the connections to the night vision. There are power supply and video cables as well as a washer fluid hose that connect directly to the back of the camera inside the driver's side kidney grill.

The night vision camera actually has a washer jet on the lens to keep it clear just like the headlights which we thought was pretty cool, something you don't think about. After we removed the washer fluid hose and capped it off the bumper was removed and we could access the area behind the grills to install the ram air scoops which collect air flowing through the grills and forces it into the air intake inlets behind the headlights. The install of these scoops was simple.

After the scoops were installed we continued on to remove the stock air boxes and stock mass air flow sensors to switch them over to the new Gruppe M intake piping. The fitment was great and there were no issues with installing the OE Bosch sensors into the Gruppe M piping. As we began to install each Gruppe M piece we had absolutely no fitment issues at all. Everything lines up as it should. All the hardware needed to install the kit is provided, including the hose clamps, screws, and bolts.

We are extremely happy with the install of this intake. The directions were as clear as they could be with the needed translation, each component of the Gruppe M intake was flawless both aesthetically and functionally. Each part fit perfectly, as if it was original equipment. The one thing we would improve is to make the photos in the instructions a bit bigger. Other than that minor complaint we would recommend this product for any M5 owner looking for a high end intake that looks great and fits great. The carbon scoops behind the front grills look awesome as well as the carbon air boxes and intake tubes under the hood. The high quality look of the carbon fiber really compliments our M5, improving the look of the engine compartment. Stay tuned to hear our first impressions of the intake as we put some miles on our M5.

This mass air intake system is designed to harness the maximum amount of air available in the F10 M5 engine bay. Careful testing went into the production of this Carbon Fiber system. The air is directed from the rear of the front grill directly into the intake manifold. The air flow is greatly increased within the 4,000-5,500rpm range where the M5 makes the most power adding approximately 15hp and 30 ft lbs of torque.

Gruppe M First Impressions:

Hands down, the best part of this intake is the sound. On acceleration the turbos are way louder. The car sounds amazing when you reach the 5000 RPM mark with turbos at full boost. The intake also gives the car a significant blow off sound as well. When getting off the throttle the boost is blow off to atmosphere through the intake.

The intake is rated at +15HP and +30 ft-lbs but its extremely hard to tell in a car that is already making over 560 HP and 500 ft lbs of torque but based on sound alone the car seems more powerful!

H&R Sport Spring Intall

We installed the H&R Sport Springs on our F10 M5. H&R springs are designed to lower you vehicle to improve handling by lowering the center of gravity, thus decreasing body roll and weight transfer. They also reduce that annoying fender well gap on BMWs with stock suspension. Although the new M5 does come from the factory with a lowered ride height from other F10 5-series it still needed to be a bit lower. We were a bit hesitant to put springs in this car because of how good the stock ride comfort and handling was, the EDC system on this car is fantastic. That being said, H&R springs are the best out there and we knew they could only improve the car. They are one of the first upgrades we perform on any of our project cars from our E92 M3 to our ActiveE Electric 1-series and X3.

The Install:

The install of these springs took approximately 6 hours. It involves removing all four coil over (spring and strut assemblies) from the vehicle. Each coil over plugs into the EDC system which makes the removal and install of the strut assemblies a bit tricky, especially in the rear where you need to access the top of the strut from under the rear deck tray. You must remove the rear speakers and some trim pieces to access the the EDC harness and the 3 bolts holding the strut.

The most difficult and time consuming part of doing the spring install is making sure there is ample room to remove the rear strut assemblies without damaging the EDC harness on the strut its self or anything around it like the electronic emergency brake. We found the best way to do this is to disconnect the rear sway bar, remove the rear caliper with electronic emergency brake and disconnect the rear control arms. This gives plenty of room to pull out the coil over strut out of the rear wheel well. Other than that the install is relatively straight forward, the front is basically just like most other BMWs.

The springs lowered the car exactly 1 inch in the front and a little over inch in the rear giving the car a great stance with a small amount of rake. We love the look of the car with the H&R sport springs, just the right amount of lowering giving the car a bit more of an aggressive stance.

Driving Impressions:

The comfort of the ride is virtually unchanged, especially when the EDC is set to comfort mode. You begin to feel the difference when you put the car into sport and it stiffens the dampening. The car is a bit stiffer going over certain bumps and changes in the roadway surface but they are very minor. The body roll is significantly decreased and acceleration and braking feel better. Before you could feel the rear of the car hunch down when on wide open throttle and you could feel the nose drop when threshold braking. Those symptoms of the stock springs seem to be minimized with these H&R springs which makes the car a lot more fun to drive. The steering also feels a bit sharper in all steering modes while still tracking down the road as the stock set up did. Overall we feel these springs are a great fit for any M5, there is very little compromise in stock ride comfort for less body roll and sharper handling. These springs are very well matched to the F10 M5 so if you are looking for a relatively inexpensive but significant improvement in your M5s stance and handling you cannot go wrong with H&R. view springs here.

UPDATE: Turner F10 M5 Race Inspired Axle-Back Exhaust

"The F10 is clearly one of the fastest, best performing BMWs ever made. It's deceivingly fast - the first thing this car needs is some exhaust noise to go with all this power" Will Turner

With the twin turbos and extensive sound deadening materials the engine sounds are too distant and unexciting. It's so quiet in fact that BMW had to develop a soundtrack of the engine to play through the stereo just so you knew it was there. With the windows down or from outside the car there is a slight hint at what the M5's V8 is capable of. How about exploiting that sound and letting more of it be heard? The new Turner Motorsport race-inspired exhaust will release more of that glorious M5 thunder!






That the M5 is so quiet is suprising given the lack of resonators and mufflers in the exhaust system. A look at the stock exhaust reveals a very open system. From the back of the turbos to the tailpipes there is only: small catalytic converters, a pair of moderately-sized resonators, and a pair of small mufflers. Any increase in volume would have to come from removing the factory mufflers. Muffler delete modifications are a recent trend in the BMW market. They offer a way of getting more volume from an exhaust, a modest power gain, and a nice weight savings. It's been very common with V8 E39 M5 owners. So with our Frozen Grey M5's mufflers barely a few months old we took a saw to them and set about developing a highly crafted axle-back exhaust kit.

From the start of development our #1 goal was to have a finished product worthy of a $100k+ car. While cutting out the stock mufflers is 'easy', applying the finishing touches and providing high quality pieces is what takes the extra effort. Any muffler shop can weld on some pipes or even a set of universal tips. But our final product is as nicely finished and well manufactured as the OE exhaust it replaces. We use a 304 stainless steel, mandrel bent 1-piece tubing in the same pipe diameter as the factory system that also re-uses the factory hangers. To meet market demands we specified two tip styles - brightly polished stainless or polished piano black tips. Once the mufflers are removed, our kit simply clamps to the stock exhaust pipes. The tips fill out the rear bumper perfectly and greatly improve the rear appearance.

The mufflers create backpressure which makes the turbos work harder. Testing with a DynoJet came back with a 14hp and 19ft-lb improvement over the stock exhaust.

The Install:

Removing the mufflers involves cutting them off the exhaust but this can be done with the whole exhaust remaining on the car. Of the M5s that we have inspected, all had dimple marks to use for a cutting referance. Once we measured and marked where to cut we used a standard sawz-all electric saw. After de-burring the pipes with a file we applied some Acousti-Seal sealant to the edge and slid the new straight pipe on with the clamp. Remove your original hangers and reinstall on the new pipes. Repeat for the other side. We left everything loose so we could get the tips positioned perfectly. Slide the tip section onto the pipe and align within the bumper opening. Once you're satisfied, tighten the exhaust clamps all the way. The kit comes with plugs to cap off the vacuum lines for the start-up valves. Total time for our first install was under 1.5 hours and we were taking our time.

First Impressions

Immediately upon initial start-up we were smiling. The exhaust barked back at us with small pops and burbles thereafter. This is mainly due to the absence of the butterfly valves installed at the factory to quiet start-up noise. Revving it in the shop produced a fierce ripping sound that perked the ears of anyone within hearing range and drew them in for a closer look. Revving the exhaust released more of that snarl and we knew this mod would be a winner.


In Depth Impressions

Out on the road the exhaust is still quiet. There's just not much exhaust noise that overwhelms the Active Sound system. We've seen full exhaust systems for this car that don't make much of an impact on sound within the cabin. The turbos keep exhaust volume lower than anything else. And with the Active Sound managing engine noise equally throughout the cabin there won't be much difference with performance muffler upgrade. With the radio on and the windows up the muffler delete pipes are not a massive change from stock. But roll the windows down and there's no longer any doubt that you're behind the wheel of an M car. The sound is very much like the stock exhaust note but it's louder and with every downshift the exhaust pops with more vigor. Change into a higher gear for cruise and it's as quiet as any luxury car. But drop down a gear or two and exercise your right foot and you're met with a bark and roar. There's a Jekyll and Hyde persona at play here. We tried very hard to get this system to drone and we only witnessed it under 2,000 RPM in too high of a high gear (i.e. 'lugging' the engine). On the highway at 70-80 MPH there is no drone at all.

At under $1,500 this kit accomplishes much of what more extensive and more expensive systems do and it looks the part. A complete and quality product was our first requirement. If it looked homemade or like it came from a chop shop garage there would little chance a product like this would survive first impressions. But by engineering the system correctly and designing it expressly for the M5 we're proud to install it on our own car and offer it to like-minded customers. It's an excellent choice for someone who loves the stock sound and just wants to hear more of it. If you want to alter the sound and create a different aural experience, there are other systems that will do that. But this kit is designed to enhance the stock sound, improve the looks of the exhaust, and be right at home on a car of this caliber.
