  • First Rally for the Motorsport-Tools Escort Mk2

    Well finally we got to take the Motorsport Tools Escort Mk2 out on a competitive event, we competed on the Toyota Harlech stages last weekend, unfortunately it was a DNF due to a slight problem with the hydraulic clutch master cylinder, but we got to test the Escort on a rally and we did 6 out of 8 stages so not too bad.

    The event took place on the Llanbedar airfield near Harlech, North Wales, local to us, just down the road and was organized by our local motor club Harlech and district motor club. Well done to them on a very well run event.

    The couple of weeks leading up to the event was very dry and sunny so we stocked up in some hard compound tyres, the airfield tarmac is very abrasive so hard compound is a must when its dry, but typically the day of the rally it poured down all day with a lot of standing water, so our slick tyres were not much use, it was very difficult puting the power down, the rear wheel was spinning in 1st, 2nd and 3rd gear and loads of sideways!

    It was the first time we got to use the Quaife 60g gearbox in anger, and it was a pleasure, worked great with very nice gear changes up and down, the ratios were spot on. The Millington Diamond 2.5L engine was also great, never missed a beat all day and has loads of torque, pulls like a train!

    Overall a good test and shakedown for the Escort, cant wait to get out again, next event Anglesey circuit in June.

  • New Group4 Atlas Axle for the Escort

    Today we take a look at the Escort's axle, The Atlas is based on the Ford Capri axle and was used on the works Group 4 Escorts as a stronger alternative to the standard English axle. The Atlas axle is still used today on Escort rally car due to their reliability.

    This is the wide version for use with tarmac arches, thick tube casing with diamond shaped 4 link brackets. Alloy brace and watts linkage diff cover. Internally we have used a Gripper LSD and a 5.1:1 ratio crown wheel and pinion.

    Fully floating, twin tapered bearing rear alloy hubs with heavy duty half shafts and alloy flanges with group 4 studs. The fully floating rear hubs have the bearings located on the out side of the axle casing which takes the full weight of the car. The half shafts only transmits torque from the diff to the wheels. The half shaft and flange can be taken out without removing the hub assembly.
