To enhance fuel curves and ignition timing we've selected performance engine management software & computer chips developed by Jim Conforti, Active Autowerke & Dinan Engineering. Performance software development takes a lot of time, knowledge & resources. These BMW tuners have the technical knowledge & facilities to engineer BMW engine management performance software that really delivers…Call us for your vehicle’s application.

In its most basic form, the internal combustion engine is nothing more than an air pump. Hence, to develop more power, an engine needs to pump in, and also pump out, more air & fuel. On a normally aspirated engine, an increase of intake air flow is achieved by running different air intake systems and CAMs. Air intake changes are not only limited to air filters and air intakes, but also differently shaped intake manifolds as well as cylinder head intake porting. Different CAM profiles vary how far and how long intake valves stay open for that gulp of air & fuel.

Super Chargers

Super Chargers literally force-feed an engine its air/fuel mixture. The engine via its accessory belt system drives an air pump known as the “blower” that pumps air into the combustion chamber along with extra fuel. This extra volume of air raises internal engine compression & generates quite a bit of power. As a rule of thumb, at 5 psi of boost pressure, one can expect about a 40% increase in peak engine power. Super charging today’s BMW is no simple matter. Companies selling such systems need to have an in depth understanding of BMW engine management systems in order to properly meter the correct ratio of fuel. Otherwise you’ll be living with an emissions nightmare and a poorly running engine that’s not long for this world.

At Schneller we have installed many Super charger kits from a variety of manufacturers.

Getting rid of exhaust is as important to making power as taking in the air fuel mixture. To this end we offer header systems, hi flow CAT converters and performance CAT back exhaust systems. Furthermore, power doesn’t necessarily come with increased noise. The following manufacturers offer quality stainless steel systems with a smooth rich exhaust note:

What can a gearing change do for you? Without getting too technical, imagine if you had two cyclists that were identical twins and therefore produced the same amount of ``leg" power. Let's place these two side by side on their bicycles and engage them in a short drag race. However, one cyclist would start off in fifth gear while the other would start off in tenth gear. Obviously the cyclist starting off in 5th gear would beat his sibling off the line in acceleration. The same is also true with your car. Put more power to the rear wheels through better gearing and the car will accelerate quicker. But what about top speed you say? Wouldn't it be reduced? In theory, yes it would, but in reality it won't.

Here's and example: Let us choose a very non-aerodynamic BMW, an `88 535. If you did the math, this BMW should in theory go 175mph with its 3.25 rear end gearing. In reality an `88 535 will top out at about 130mph even though the motor hasn't hit its rev limiter at redline. Why? The `88 535 doesn't have the horsepower nor the aerodynamics to overcome wind resistance to propel itself to that speed. However, if we reduce the gearing load by installing a 3.91 rear axle ratio, this same car will do about 145mph.

~We offer a range of gearing options for various models old and new. In many instances we can provide you with a clean, inspected, quality used rear end at a reasonable cost. But if you prefer, custom built rear ends are also available. Each car and driver are different. Call us for details about your specific application.

One way to make your car faster is to fit it with a bigger more powerful BMW engine. At Schneller we specialize in transplanting the larger, more powerful BMW power plants into the smaller and lighter chassis BMW cars. We’ve converted  over 30 vehicles since 1994. We’ve built cars that the factory didn’t including  the 360HP e30 M335, a 300HP e30 M330i, a 360HP 6 speed manual e32 M7, a V8 powered 300HP e30 340i, a 300HP e28 530i, a 300HP e36 318ti, and an e34 M5 Touring Wagon conversion. Due to the more complex electronic systems and emissions standards of the newer BMWs, older vehicles are easier to convert than the current models. However, almost anything is possible. Call us to discuss your ideas.

We also sell electrical instructions and conversion parts kits for the e30 M50 S50/52 drive train conversion. Call us for your needs.

Work In Progress…  

At Schneller we take a balanced approach to designing a suspension for our customers. Handling should match and compliment the power of the vehicle, yet not make the car unbearable to drive.

Before altering your suspension, you need to ask the question why? Is it because you primarily want a different look? Do you want to upgrade the handling of your BMW? Or do you simply want to replace worn out components and restore the stock ride of your vehicle.

It's easy to end up with the wrong suspension given the primary use of your car. Something that works well at the club driver school or autocross may not be the best for commuting on the bumpy streets of Boston. Call us and we'll help you design a suspension that will fit your needs, and not just sell you the one that happens to be on sale this week.

At Schneller we install quality components from the following manufacturers:

Sway bars will help reduce the body roll of your BMW, but so will stiffer springs. Like stiffer springs, thicker and stiffer sway bars will also add ride stiffness to your BMW as the bars will be forced to twist when your wheels travel independently of each other over bumps in the road. You will need to consider this factor in assembling a suspension that's right for you. More than anything, sway bars will alter the handling characteristics of your car. Typically most sway bar kits will dial more roll stiffness into the rear of your chassis hence enhancing turn in or over steer.

This is great if that's what you're expecting the sway bar kit to do. But many people have the misconception that the sway bars will actually help them stick to the road, that the rear sway bar will actually control the rear end of the car. This isn't true and these misconceptions can leave you swapping ends on a wet off ramp. We recommend some club driving schools and some experience getting used to a new sport suspension so that you can understand and feel the difference a set of sway bars will actually make in your car. Call us for further advice on sway bars and suspension tuning.

Whether you've got stock sway bars or bigger bars, don't forget to examine the condition of your sway bar links. Loose or broken links will alter the handling of your car and may be the source of mysterious suspension clunks.

Handling Problems

Does your car handle like a dish pan of water? While driving, is there enough play in the steering wheel that you can move it right or left about an inch without actually changing the direction of the car? Does your car pull of in one direction under acceleration and off in yet another when lifting off the throttle? Do you have some mysterious clunks that occur while going over bumps, or when transitioning on or off the throttle?

These are all signs of worn out suspension and steering components such as control arms, control arm bushings, ball joints, tie rods, steering track rods, steering idler arms, trailing arm bushings, or rear sub frame bushings. Before you even consider a new set of springs and shocks you'll need to ensure that these components are in safe working order. Any BMW with 100,000 miles will certainly need to have these components looked at. Call us for recommendations on replacements parts.

Based on our 14+ years of tuning BMWs, believe us when we say that urethane, non rubber solid mounts & bushings, adjustable camber plates & adjustable coil over suspensions are for track use only. Using them on the street & driving them through harsh conditions (Freezing temperatures, snow, salt, sand & rain) will ruin these components & your car’s unibody structure.

That being said, these purpose built components will raise the handling of your track car to new heights.

We sell suspension components, bushings & mounts based on solutions to customer stated handling problems and class racing rules that dictate what types of components may be used. Please call us for your racing suspension needs.

We offer:

Urethane Subframe mounts

Solid Control arm bushings

Various Solid bushings & mounts…

All of these components will require professional installation, chassis realignment & set-up. Call us to discuss your suspension needs or schedule an appointment for a chassis evaluation.

Going faster is great, but at some point you’ve got to slow down. The best suspension & stability control systems on the market can’t yet defy the laws of physics. If you’re too fast into a turn, you may be in trouble.

Stock BMW braking systems are very good and very difficult to outperform during spirited street driving sessions. However, if the vehicle has received a major boost in power or is being used as a track vehicle, improvements may be in order.

Most track applications respond well to:

• A change in brake pad compound…better bite & less fade at higher temperatures

• Stainless steel brake lines….Improved pedal feel & durability.

• Brake cooling ducts….cooler brakes work better!

• High temp racing brake fluid…higher boiling point for a firm pedal under racing conditions.

However, if these improvements still don’t dissipate enough heat & sufficiently stop the vehicle from speed, then larger brakes may be in order. Call us to discuss your performance braking needs.
