Testing, development and preparation for Mamhead

(download)

A good afternoon was had testing the Pulsar 931 at The Haynes International Motor Museum, Sparkford. Given that the car had not turned a wheel in anger since September 2008, we need to make sure all was good and bring to the surface any issues that will need resolving before an outing at Mamhead in two weeks time on the 29th May.

A few sedate laps started our session and nothing fell off, which was a good start. Some more laps were needed to bring the brakes back into condition, Some 'spirited' laps were later put on the car without any major issues. In total we ran around 30 laps. The only issues that we found were: a minor mounting issue with the new diffuser, a small weeping of fluid from the differential housing, a failed wheel stud and issues with the seat mounting.

All the issues have now been resolved and we have one more development in the pipeline that we can't wait to see on the car: new rear-wing end plates that Ben from Bazzworx is developing as part of a CFD (Computational fluid dynamics) design project. These sexy new bits will have half the drag of the old end-plates with no loss of downforce. Pictured are the wind-tunnel models ready for testing.

That'll Do!

A good day was spent fitting the last few panels, undertaking a nut and bolt check, checking all systems, firing up the engine and running up through the gears with the car still on stands. Most impressive was that Lynsey was able to still fit in the seat! A much used phrase during our preparation was "That'll Do" which has now been adopted as Lynsey & Mark's motto.

The eagle-eyed among you will notice a missing wing end-plate. This is because Ben has been playing with CFD and has designed replacements that have half the drag. We've seen the pictures and they are even pretty. Hopefully they'll be in place for our test at the Haynes International Motor Museum, Sparkford (www.haynesmotormuseum.co.uk) on Wednesday afternoon.
