About the Components
Adapter Plate
Machined from T6061 billet Aluminum , the adapter plate is profiled to allow a smooth transition from the OEM port opening of 70mm to the opening of the throttle body at 75mm. All adapter plates come standard with a 1/8” NPT tap for water/methanol injection and a plug should you not have methanol injection. Choosing a Bosch throttle body as a basis for our product allowed us to work with a more compact in size throttle body. This meant that getting a throttle body behind the cylinder head and bolted to the supercharger inlet did not require a cast adapter (expensive to machine an offset adapter) making our adapter more affordable to manufacture which means the end user / customer gets a financially appealing solution.
Throttle Body
We use a Porsche 997 Throttle Body (Manufactured by Bosch in Germany). The OEM Part Number used is 997 605 115 01 (BOSCH #: 0 280 750 474) for the 75mm unit and 997 605 116 01 (BOSCH #: 0 280 750 473) for the 82mm unit.
Our throttle body’s come with a limited lifetime warranty to the original purchaser (good luck getting that from any other vendor on an electrical component).
Adapter Harness
(Commonly Known as the boostbrat coined By John Rapkoch)
Our adapter harness is the culmination of 2 years+ worth of R&D. We have a specialty designed circuit board that allows the conversion from Siemens/VDO/ Continental 11Kohm to Bosch 1Kohm making this plug and play for all applications. The circuit board is enclosed in a T6061 CNC’ed billet housing and epoxied to ensure functionality under all weather conditions (i.e. no water is getting into this thing…) . The pigtails are OEM Porsche for the throttle body and OEM Volkswagen /Audi for the harness side. We only use OEM pins in our harness construction to ensure operation is the same as OEM.
Finally the harness is wrapped with electrical wrap and covered in aerospace grade fire retardant wrap. The orange colour of the fire retardant wrap makes the completed unit look like a sausage (which we are okay with).
This also allows similar sized 70mm DBW throttle bodies from the B5 S4 or Porsche 986 to work on the 2.0 TFSI Turbo motors.
Us vs them FAQ
Throttle Body
When asked why we didn’t use the Dodge Hemi 5.7L / 6.1L Throttle Body in our offering , the answer was simple.
Like all of our products , we advocate for the use of certain brands. Similar to Fluidampr for Crankshaft dampeners , Mahle Motorsport for Pistons , ARP for hardware we believe Bosch (Bosch Motorsport) offers the absolute best Drive By Wire (DBW) throttle body on the market place. The construction of Bosch units vs competing Siemens/VDO/Continental units is superior and they are more compact due to the family sharing of components such as TPS covers and drive motors.
We have been in the drive by wire throttle body game since 2004. It is no secret that the Dodge Hemi unit is the affordable “go to” throttle body by most aftermarket companies because of the following factors:
- They are cheap.
- They are manufactured by Siemens / VDO in Germany (Yes the Hemi has a German part on it)
However, we don’t use VDO/Siemens units for a few reasons:
- Construction (as mentioned above) - unlike Bosch , Siemens/VDO throttle bodies are manufactured as affordable as possible . Reinforced Plastic is used for throttle plates where aluminum should be used . In high horsepower 2.0 Turbo applications , the throttle plate’s snap into 2 pieces which may cause catastrophic engine failure should they go un noticed. Bosch throttle bodies will never fail in this manner.
- Water/Methanol injection – Bosch units have seals between the throttle shaft and the housings so if you are spraying meth pre throttle body , the likelihood of the meth crystallizing on your circuit board is slim to none. This is a major reason most VDO units fail in a water / meth setting.
- Ability to rebuild – Siemens/VDO units are not serviceable , where as , Bosch units are. Unlike other outlets we offer a limited lifetime warranty on our products .
