Back to Harewood again for the final time of the year.

 

Harewood hill climb course map.

The course is 1448.25 metres long. The map is from www.harewoodhill.co.uk

 

 

Car Number 136.

Set Up: After the last visit with the stiffer springs I decided to stick with the soft springs I had refitted.

Springs: (Front 200 LB/inch, Rear 250 LB/inch)
ARB: Drop link on the rocker in the middle hole and the neutral position on the bar.
Dampers: Front Bump 6, Rebound 6. Rear Bump 4, Rebound 3.
Differential : 3.91 LSD (7")

 

1st Practice Run                    
64ft...........2.57 sec's              
Split 2........24.67 sec's           
Split 3........14.93 sec's           
Split 4 .......16.36 sec's           
Split 5 .......11.27 sec's           
Speed ........               
Time ..........69.80secs         

Notes: Track was damp in places and there were a few spots of rain, tramping off the line and understeer when under power in the middle part of the corner.

2nd Practice Run                   
64ft...........2.50 sec's             
Split 2........24.41 sec's           
Split 3........15.07 sec's           
Split 4 .......16.35 sec's           
Split 5 .......11.18 sec's           
Speed ........                
Time ..........69.51 sec's          

Notes: The track was dry but it was spitting with rain. There was an oil spill from Country to Willow. It felt like I was very fast into the first bend. The car felt stable and balanced on this run.



1st Timed Run                      
64ft...........2.47 sec's              
Split 2........24.13 sec's           
Split 3........14.84 sec's           
Split 4 .......16.29 sec's          
Split 5 .......11.22 sec's           
Speed ........75 mph                
Time ..........68.95 sec's          

Notes: Still understeering. So for the 2nd time run the ARB was softened by moving the slider to the other side of the neutral line (25mm)


2nd Timed Run                      
64ft...........2.57 sec's              
Split 2........23.84 sec's           
Split 3........14.99 sec's           
Split 4 .......16.21 sec's           
Split 5 .......11.20 sec's           
Speed ........75 mph                
Time ..........68.81 sec's          

Notes: Oversteery, a scrappy run (even though it was my quickest of the day). So for the final run of the day I stiffened the ARB back to the days starting point but only on one side (stripped bolt). So effectively the roll stiffness was mid way between the previous run and the start of the day.

3rd Timed Run                 
64ft...........2.49 sec's              
Split 2........24.21 sec's         
Split 3........14.78 sec's          
Split 4 .......16.06 sec's          
Split 5 .......11.10 sec's           
Speed ........75 mph                 
Time ..........68.64 sec's          

Notes: A personal best on my last run of the year at Harewood!! The felt balanced and the fast time was due to me trying to carry more speed into the bends.

Summary: A very good day. All runs were under the 70 second mark even with a damp track and spits of rain. Moving the ARB slider 25mm along the bar makes a big difference. The greatest distance I should adjust the slider is 12mm. I got axle tramp when doing the first pre start burnout but not the 2nd or 3rd or at the start.

 

These are the split times from this meeting arranged in a table for easy comparison.

Split1: 64 ft, Split 2: Entrance to Country Corner, Split 3: Exit of Orchard Corner, Split 4: Exit of Farmhouse Bend, Split 5: Finish line.

Combining my best split times gives a theoretical best time of 68.18 seconds. I feel that under 68 seconds should be possible. I am still loosing time from Country Corner to the exit of Orchard Corner. I am sure most of this is around Willow Bend, this is fast with very little run off. If I get it wrong here the chances of damage are quite high. At the first part of Orchard Corner I really cut it so much that 2 wheels are on the grass, most people stay with all 4 wheels on the tarmac so I must be gaining time here.

M Geen is on road tyres in a modified 1.4 litre Peugeot 205. He is the class record holder. This time is for comparison.
