common sense very vague.Karthik said:
Common sense do not race your motor until all liquids,oil and water have reached optimum level and the cylinder head at 90 degrees.
Common sense allows your car to cool off sufficiently between runs so that liquids can return to normal temperature.
Common sense is knowing if you drive fast you will use more fuel.
Common sense is knowing to use the right octane level of fuel.
There is a huge difference between trashing a car and driving fast.
Modern day vehicles have not been built the same as previously and parts and materials have all changed.If you drive your car for too long at low RPM you will glaze the cylinder bore.
Run it in too long and it will run out before it runs in.
Vehicles already have enough run-in on the benches so that when the cars hit the showroom floor a zealous customer can not break a motor that has not even reached temperature.
Where there are issues the factory will with software discipline the driver.For instance BMW vehicles will not produce maximum power until sufficient mileage of run in or temperature has been achieved.
A story to end.Lady was doing an arrangement of flowers and cutting off the stems as she thought was normal.Her little girl asked why and she said "thats how my mother taught me".The little girl then went to grandmother and asked why the stems had to be cut.Grandmother said "dearie in the old days they never made vases that were tall enough".
:biglol:
Hope you catch my drift.
Cars are like people.Iwould rather enjoy and use 60 years than just consume oxygen for 100.
Have a nice day all fanatics.
Read some of my previous datalogging threads all that info has been given in the past.Chavoos said:
As far as the track goes do you know that we had events at the Vanderbijlpark airfield every month,with ER24 and fire brigade,and these events were very poorly supported.This opportunity was eventually stopped because the cost of holding these secured events was too costly.
We have also afterwards had requests from certain parties who behaved like hooligans and so because there is no way in advance of knowing who turns up a decision was made to keep the facility closed.
My advice is go to ODI.I did inspect and drive there 3 months back and i am quite satisfied with their setup.The datalogs I did there are very similar to where i test.
There is a meeting on the 2nd March 2014 and on their site all the other dates.
I have no affiliation to ODI but would suggest that fanatics enjoying speed use them as they might also disappear if no support is given.

Those are nice results.

Depends on how it's broken in...
My old 4.2 S4 had an engine replacement a few years back after a moneyshift.. drove it sedately and kept the revs low for about 100 km, checked the fluids and all the pipes, and then took it on a highway run, where I'd accelerate from low RPM up to high RPM slowly... did this for another 50 km.
Changed the oil, and thereafter, it was balls to the wall - and my S4 with stock cams churned out the same power as one with identical mods and a set of regrind cams, and it never used a drop of oil.
So there's merit to the "running a car in hard" school of thought IMHO - as long as you observe the right warm-up sequence, etc and at least give it a gentle bedding in initially.
Exactly right. First learnt this method when i was building hotrod motors where there was no choice but to do a number of laps on the circuit. 20 laps as you describe and the motors were good to go. Also never had any blowby and this on a motor that is constantly at high revs for ten laps.BillyBob said:
