- Top speed 305 km/h (190 mph)
- Perfmormance data are obtained by a Greek Automobile Magazine with V BOX of RACELOGIC.
- DA MOTORSPORT M Roadster supercharger kit includes ASA Infinitas supercharger unit. The rest of the system is designed and produced by DA MOTORSPORT.
- This supercharger kit can be used on E36 M3 3.0L Euro version (S50B30), E36 M3 3.2L Euro version (S50B32), M Coupe Euro version (S50B32) and M Roadster Euro version (S50B32). This supercharger kit cannot be installed on US version M Roadster.
- After seven years of research, design and testing DA MOTORSPORT is proud to release the S50B32 supercharger kit. We have tested over 30 "compression ratio vs boost pressure" combinations on the S50B32. For a daily driven supercharged M3 we found out that standard compression ratio of 11,3:1 and 8,5 psi of boost pressure yield the best "performance, driveability and low engine speed torque".
- DA S50B32 supercharger kits utilize ASA Infinitas superchargers which are known to be the best.
- ASA Infinitas superchargers' high ratio internal transmissions, 15:1, enable to rev the supercharger 120.000 rpm. Other brands of superchargers have lower internal transmission ratios such as 3,45:1. As a comparison, ASA Infinitas superchargers build boost at lower engine speeds than other superchargers. This feature of ASA translates into more power and torque at low engine speeds.
-ASA Infinitas superchargers' belt system is designed to survive under racing conditions. Supercharger drive belt system allows a limited amount of belt slippage during fast down-shifting of gears and preserves the life of the v-belt.
- DA Motorsport S50B32 superchargers are HD version. HD version superchargers are equipped with ceramic ball bearings instead of conventional bearings. Ceramic ball bearings allow high supercharger speeds of 120.000 rpm.
- In order to find the best supercharger we have tested different brands such as Vortech S Trim and T Trim. Only ASA Infinitas superchargers survived under racing conditions.

ASA Supercharger
and Supercharger Clutch
- Supercharger and supercharger clutch installed on the bracket.
- ASA Infinitas supercharger, TM I 20 hd
- Maximum supercharger speed 110.000 rpm
- Air flow 2.000 kg/hour
- Compressor housing intake diameter 70 mm
- Compressor housing discharge diameter 60 mm
- Supercharger clutch KO7. ASA superchargers have clucth systems which engage the supercharger above 1.100 rpm. This special feature enables smooth drivability in stop-and-go traffic and during parking where no supercharger is needed.
Intake Manifold Kit
- Intake manifold production starts from scratch.
- Aluminium is used to withstand high boost pressures.
- Runners' length are designed to improve air flow at high engine speeds such as 9.000 rpm.
- Intake plenum welded to the runners, aluminium.
Intercooler Kit
- Front mount aluminium intercooler core
- Aluminium end tanks, polished
- Intercooler brackets, polished
- Intercooler pipes 314 Stainless steel, polished
- Stainless steel "crossbolt clamps" hold silicon hoses securely. Spiral rolled- edge clamps are NOT used
- Intercooler installed on M Roadster Supercharged.
Exhaust system
- Hand made race cats, stainless steel 314
- Hand made rear mufflers, free flow stainless steel 314
Engine management system
- TSI Engine Management System is used to adjust air fuel ratios and ignition timing.
- TSI is NOT a piggyback system, TSI is an engine management system. Each injector is driven individually by TSI.
- DA M3 & M Roadster supercharger kit do not include a rising rate fuel pressure regulator. Our kit runs at standard fuel pressure and preserves injectors' life. TSI adds fuel by changing injectors' duty cycle.
- TSI is configured to enable both fuel injection and ignition timing alteration. Each is independent of the other, allowing the tuner to only alter the part of the mapping required (unlike many other products who alter the air flow meter or the manifold absolute pressure sensors to tune fuel, which also alters ignition timing where it is not required)
- Air flow meter is removed and a 22 psi internal map sensor is installed for accurate air flow measurement. Air flow meters cause problems in forced induction aplications. TSI allows to map air fuel ratios for each gear individually. As turbocharged engines produce different boost pressures at different gears due to load variations, map sensored based mapping provides the ideal air fuel ratios in all gears.
