N62 supercharger set ready for take off

Hello guys,

Finally came to the state that the supercharger kits could start the selling phase.

What we’re talking about:

A twin-screw supercharger kit which fits all the N62 engines. E60, E63, E65, X5 series.

Attention, 4.4 and 4.8 engines have different ECU, therefore they will first be available for the 4.4 version.

Mainly it’s a plug and play kit however still DIY therefore probably there’ll left some stuff which needs to be solved on your own. For example check under hood fitting, and to fit an intercooler heat exchanger. The reason of this I focused to fit nicely to all N62 engines however each chassis is different therefore it’d have been a hughe challange and necessary to get test vehicles from all series. The rest of the job should not be a big deal.

The following parts will be in the kit, what I divide to 3 parts.

  • TheCrazyDIYengineer’s hardware kit: This contains all the adapters to fit the LC3 Caddylac supercharger.
    • Adapter plates
    • Crankshaft pulley
    • Supercharger pulley
    • Tensioner bracket, tensioner, belt
    • Intercooler hose adaptor
    • Pressure sensor adapter
    • Fuel rail
  • TheCrazyDIYengineer’s tune
  • Parts to be sourced externally:
    • Caddy LC3 supercharger
    • Injectors
    • Intercooler heat exchanger
    • Intercooler water pump
    • Expansion tank
    • Some hoses, miscs part, or parts needed to be relocated
    • Gearbox map –> If you have auto trans (XHP Flashtune)

Please be aware that the hardware kit and tune needs to be purchased together. Selling alone is not possible. It is also not possible to sell individual parts from the hardware kit.

Pleae be aware that ONLY 1 specific type of injector going to be used in the kit, therefore you need to source the specified one. Other injectors not going to be mapped this stage. Be aware and stay away of the chinese copies! If you want to make sure I can supply them also in the kit.

If you’re interested and willing to get one please register your request in the following site: Pre-Order form

Tuning on an engine dyno will be done in October-November so this will be a very nice winter project!

Prices are not fixed yet and could vary.

Estimated total cost~$6 500,00
TheCrazyDIYengineer’s hardware kit~$3 000,00
TheCrazyDIYengineer’s tune~$800,00
External source~$2 700,00

Bmw 5-6-7 series Alpina supercharger set for sale

Kit contains:

  • Fully refurbished supercharger
  • Supercharger bracket
  • Cylinder head front cover
  • Supercharger pulley
  • Harmonic dampener and pulley for supercharger
  • Injectors
  • Oil feed line

This is a used but fully working set from an Alpina car.

It’ll only work with 5-6-7 series!!!

What you’ll need to solve:

  • Tubing to intake manifold
  • Tubing from air filter or sport filter
  • Tune
  • Water hose besides supercharger
  • Some small misc parts

Very last price is 4200 Eur + shipping!

New products arrived to my “shop”

  • 7. Oversized pulley for higher boost
  • 8. Clutch center nut
  • 9. Clutch elimination adapter

Check the pricing at the Supercharger repair section.

You have manual gearbox or planing to do a manual swap? This add on is for you!

This is The CrazyDIYengineer’s pnp harness adaptor. What is it good for? You can run a standalone ecu in the car, without modifying or building a new harness, just snap in this adaptor. And when you are tired of it, just remove and plug back the stock DME.

What’s the best about it?

Everything! I’ve chosen Ecumaster EMU Black for this purpose. It is a very powerful but cost effective solution! You could get the ECU + my harness adaptor and software for the price of a supercharger tune. I’ve designed this adaptor and chosen this ecu from several ones. Almost all of the factory comfort functions could be retained and you’re getting a lot of new addons.

  • This board will electronically eliminate Valvetronic and set the valves for maximum lift. Therefore you’ll have a manifold vacuum reference which means you will be able to fit any kind of turbo, supercharger or nitrous!
  • Removes MAF, and tune will be based on speed-density by the built in MAP sensor
  • You can fit any size of injectors and easily retune
  • You can add R8 coils
  • Boost control
  • Water methanol injection control
  • Flex fuel to run E85
  • Launch control
  • Anti lag control
  • Traction control with 9 sensitivity modes set by a knob
  • Additional engine protection strategies by fuel pressure sensor and exhaust gas temperature sensor

If you’re thinking tuning your stick shift 545, 550, 645, 650, 745, 750, X5 don’t waste your time tuning the stock DME! Throw it out and plug this in! Than starts the fun!

This will be unique and standalone! 🙂

How to supercharge your 545, 645, 745 Alpina style on a budget. Guides, plans, instructions

Who would be interested for such a document?

As I’m having less and less time, I decided to sell a complete instruction instead of a full kit. It’s on a budget because the parts could be sourced by yourself, made by yourself and if you have already something at home you can use it. But of course if you need something you can always ask me if I have it.

What this document will contain:

  • BMW – Alpina comparison. Differencies, how to improve your car
  • Bill of material for the build
  • Guides to modify electronics side
  • Guides to modify fuel system
  • Guides to load supercharger software
  • Guides for the build
  • 3D scanned parts for measuring and doing your own plans
  • CAD data, 2D drawings for production or 3D printing

This kit is based on the Alpina parts however Vortech superchargers or special turbochargers could be used, but those are not tested. I’ve been gathering these information for at least 3 years, I’ve invested much money into parts, scanning, manufacturing and prototyping and I’ve more than a thousand of work hours in it. Therefore I’m going to aim about 6-700 euro for this complete package!

I’m planning to release this document during October for pre-order, and ready to supply during November-December.

If you’d be interested please contact me!

Another supercharger refurbished

This sc came into my garage in the condition of the first picture. It was totally disassembled, compressor wheel was damaged, and the sc got some injuries during the shipping.

But as usual I did my best and you can find the result on the second picture. Sc fully refurbished and ready to go back to the owner. 🙂

Thanks guys!

I saw this feedback on facebook this day, what I have to share here for some marketing reasons… 😀 Actually I really appreciated it.

Actually building new parts and systems makes you very tired. Sometimes you need to think a lot, sometimes you fail, don’t have enough time to complete something and you think it’s easier to pour some fuel on your shitboxes and light a match… 😀

But sometimes (hopefully many times) you succeed and people like what you do and they appraise you. These are the words that keeps me motivated doing these things after work during the nights and weekends, and keeps me away burning down to the ground my shitboxes. 😀

Thank you guys, I really appreciate it!
