EVO 2 Soft Blue Inline Motor Mount

NSR Precision for the Mosler Evo 3 Chassis: EVO 2 Soft Inline Motor Mount

The motor mount is one of those components that goes unnoticed until the wrong one is chosen. NSR has been refining this key piece for years, and the EVO 2 Soft Blue (NSR1241) model is the answer for those seeking a more flexible working point in their Mosler Evo 3.

Function and Performance

The motor mount is the bracket that secures the motor to the chassis and determines how power is transmitted to the rear axle. In an inline configuration —longitudinal motor, in line with the car— the mount directly influences the gear mesh geometry between pinion and crown gear, as well as the height of the centre of gravity.

The soft version of this mount allows for slight absorption of track irregularities. This translates into more consistent contact of the rear tyres with the track, especially on tracks with minor elevation changes or joints between sections. The blue colour visually identifies this hardness within the NSR EVO 2 range, facilitating material management in the preparation box.

Compatibility

• NSR Mosler Evo 3 Chassis
• Inline motor configuration

If you are using a different chassis or a sidewinder or anglewinder configuration, consult the NSR mount catalogue to find the appropriate reference for your setup.

Installation and Preparation

The installation is straightforward and does not require special tools. However, it is advisable to check the alignment of the pinion relative to the crown gear after changing the mount: the variation in hardness may slightly modify the gear mesh spacing. A fine adjustment at this point makes the difference between a quiet and efficient rear end and one with premature wear.

NSR recommends combining the choice of mount with that of the tyre and the overall stiffness of the chassis to achieve the most coherent setup possible according to the type of track and race conditions.

Common Mistakes

• Mixing mount hardness with incompatible chassis configurations. Always verify that the mount corresponds to your version of the Mosler chassis.
• Not checking the gear mesh after the change. A softer mount may alter the pinion-crown gear clearance. Always check the backlash before the first session.
• Confusing the reference by colour. Within the NSR range, the colour identifies the hardness: blue = soft. Not interchangeable with other hardnesses unless the setup requires it.

Frequently Asked Questions

What is the difference between the soft and hard mounts in the NSR EVO 2 range?

The hardness determines the flexibility of the motor-chassis assembly. The soft mount allows for greater absorption of track imperfections, enhancing traction on less uniform surfaces. The hard mount offers more rigidity and precision on very flat and smooth tracks.

Is it compatible with other NSR chassis besides the Mosler Evo 3?

According to the information for the NSR1241 reference, the indicated compatibility is for the Mosler Evo 3 chassis. For other NSR chassis, please consult the specific references in the official catalogue.

Does the hardness of the mount affect the pinion-crown gear mesh?

Yes. A softer mount may slightly modify the distance between the pinion and crown gear. After each mount change, it is advisable to check the backlash and adjust if necessary.

Is this mount suitable for sidewinder or anglewinder configurations?

No. The EVO 2 motor mount is designed for inline configuration, where the motor is positioned longitudinally relative to the rear axle. For sidewinder or anglewinder, there are specific references in the NSR catalogue.
