Our First Rotrex Centrifugal Supercharger based kit is now on it’s way! We introduce you to the B.R.O.S.K. – 1. Built specifically for the racers and car enthusiasts who like to take it to the Race Track!

Short for BMW Rotrex Supercharger Kit, B.R.O.S.K – 1 was developed in house by Mas Schandorph of Mas Motorsport Wiring (M.M.W.) in in Roskilde, Denmark. The B.R.O.S.K. – 1 supports the Rotrex C30 as well as the Rotrex C38 family of superchargers.

The projects development began in 2022 and was completed this year. To demonstrate its track ability, a total of 2 BMW E46 cars (Blue 325i and Yellow 330i) were built for this kit and then taken to the track!

After being track tested over a hundred times, this kit is now approved for production this fall.  The B.R.O.S.K. – 1 is our highest power output centrifugal supercharger option so far M5x and S5x engines. With the smallest foot print yet, the robust design of the bracket system mounts in place of the AC unit, and brings forth the high efficiency and reliability found in the Rotrex brand of Superchargers.

Having a Supercharger on a BMW already is something special, but what’s more special here is unlike most centrifugal superchargers, the Rotrex line of Superchargers offer a low down linear power curve and raw torque figures, which comes close to the traditional Hyde Motor Works Roots and Twinscrew supercharger setups.

Below we showcase what very low boost figures can achieve with just the Rotrex C30 supercharger. Keep in mind, the power is measured at the wheels, which means the final engine HP figure is about 20% higher.

B.R.O.S.K. – 1. has an expected release in Early Winter of 2023 with discounted Pre Orders available from August directly through Hyde Motor Works.

Featured Supercharged Build of June 2023

After our brief hiatus in Spring, we kick off the summer season by welcoming you back with the Featured Supercharged Build of the Month of June! This time we have something different, and that is a Supercharged Nissan Micra from Hungary!

We appreciate all auto enthusiasts, not just ones who drive BMW’s. When we were reached by David about supercharging his Nissan Micra, we were eager to be a part of this build! David is from Budapest, Hungary. And this is his pocket rocket build based on a K11 1.4L (CGA3DE engine) Nissan Micra, which originally came from the factory with some 82 HP.

When we asked David about why he wanted to supercharge this cute little machine, he had the following to say:
“I only know about one turboed Micra in Hungary. People here only use it as the cheapest form of transportation. The most common budget tuning are usually Suzuki Swifts here.”

And as we see, David’s friendly kitty loves the supercharger as well! #SuperchargedCats!

It was the first week of May, when they finished the tuning of the car! Using a unit from MaxxECU for all its tuning needs, the system powered by the AMR500 generated a maximum of 110 WHP. That is close to 130HP at the crank when you account for 15-20% drive train loses. Coming from some 82HP on the stock engine, this is easily a 50-60% power gain.

According to David, the car starts to pull now from 2500 all the way to 6500. A character found on twin screw and roots type supercharger systems. The car also features launch control that holds at 4000, then switches the function off at a certain speed after launching.

David initially reached out and explained to us what he was trying to do. He did however pose us with a challenging question, which is that there are many AMR 500 online to order from for less than our price, but they “may” also come with customs and taxes (and also defects). He asked us to convince him why should he order from us.

We told David we can’t think of a better reason to buy from us other than perhaps our company lawyer and good friend of ours, Peter, who also happens to come from Hungary. Okay that may not be the best reason to buy it. 😉 – So to top it off, we get our superchargers in reconditioned state from Japan and offer a warranty period. Hows that for a good reason!

To sum it up, David is meanwhile a friend of the Hyde Motor Works team and when we do head east, towards Budapest this year, we will drop by for a ride in his Micra.

For those of you interested, Davids the Micra K11 1.4 – 2002 setup is the following:
– Hyde Motor Works AMR 500 Supercharger
– BC Racing BR RA coilovers
– Japan Racing JR 29 wheels
– Toyo Proxes TR1 tyres
– Factory size Brembo rotor and pads (rears are drums :))
– Kevlar Clutch

If you want to see more of what this little pocket rocket can do, then go watch the YouTube video below where David’s Micra is reviewed by a Hungarian Youtuber, Kekszi’s Garage.

Harbinger – P2 Centrifugal Supercharger Kit for BMW

We are proud to release our most compact and affordable Supercharger Kit yet. Introducing the Harbinger Supercharger Kit for BMW’s!

The Harbinger (Pronounced: Har – bing – er) was built with a few key principles, which are being able to offer a supercharger setup that can deliver high performance with an affordable price tag while still keeping the reliability of our traditional supercharger kits. Targeting enthusiasts that are looking for a compact option for their BMW M5x and S5x engines.

Although actual development has started in 2021, pre-development concepts of it can be found at K.C. Design Concepts, New Jersey, United States as early as 2020. The kit itself is built around using a P2 Centrifugal Supercharger unit. This is a very affordable supercharger unit produced by Speedmaster79 in Australia with manufacturer part number PCE157.1002. The P2 Centrifugal Supercharger is a dry self contained unit that does not require any external oil coolers and can be bought with a warranty directly from the manufacturer. This rather large supercharger is a direct drive unit that’s rated to be able to support up to 1150CFM and some 55,000 RPM by Speedmaster.

One of the challenges we came with when building the Harbinger was the supercharger drive system. The unit is a direct drive and sold without a gearbox to drive it, this means we had to simplify the drive system to ensure the final kit can maintain one of the key principles, which is affordability for the enthusiasts. We resolved this by designing a custom toothed COG Pulley and belt, produced exclusively by us to make this system work. The custom toothed Pulley itself had multiple concepts and sizes.

Currently, we provide the kit with only one pulley option that limits the maximum RPM and work load of the supercharger just under 80%. This is to increase the reliability and longevity for the end user. Larger drive pulleys would be an option in the future.

Being a centrifugal supercharger, the Harbinger of course behaves much different than our traditional Roots and Twinscrew Supercharger kits. With the Harbinger the power delivery is more similar to a turbocharger, where the boost starts to build from the higher mid RPM range and continues to build up as you reach a higher RPM. Being a centrifugal it is also quite efficient and provides a cooler charge temperature. This means for those wanting a low boost setup, they can use this without an intercooler.

Developed with both stock and built engines in mind, this setup will work for both factory stock and built engines with aftermarket head gaskets, rods, pistons and head bolts. While a built engine will be able to handle more power, on a stock engine, we suggest limiting the boost to 10 PSI, using a boost controller and a bypass valve.

The Harbinger will also be the first time we offer a supercharger kit in a colour other than black! That’s right, these CNC machined Harbinger kits will come in 2 different colour options, Azur Blue and Dark Yellow inspired by BMW.

With all the pre-production prototypes sold out and a future BMW N52 Engine concept in the works, currently the final Harbinger kits are in production and available for ordering with a late May 2023 delivery schedule.

You can Pre-Order the Harbinger today from our Shop.

Watch the video below from Keith to find out more about the kit and how simple it is to install on on your car!
