Thread Inserts (2)

[email protected]
In the previous article on thread inserts, Wayne Ward briefly discussed some of the reasons why people might choose to specify a thread insert and looked in a little detail on one of the types of insert which find common use in current racing engines. There is one further reason why a wire insert may be an advantage and that is in improving the fatigue life of the bolt installed therein, or of the female threaded component. Previous articles that I have written on the subject of fasteners...

Fuel for thought

[email protected]
Maybe I'm getting old but when I see racers the world over spending thousands of pounds (or dollars) on their winter engine rebuilds and then running them on ordinary pump fuels, I simply begin to wonder. By the time they have prepared the car, transported it to the circuit, paid the entry fee and fed and watered their little army of helpers, with any of the budget still remaining, you would have thought that they would have planned to fuel the engine on something just a little bit...

A load of hot air

[email protected]
It has often been said that I talk an awful lot of hot air. This comment, I hasten to add, is one more frequently voiced from members of my immediate family but this month, somehow and when associated with lube oil systems, the phase has much more of a resounding ring. This month therefore, I want to talk about the scavenge pump in a dry sump system and how big does it really need to be? The answer, as you might expect, is not that simple but let us look at what we are asking the scavenge...

Piston strength wins races

[email protected]

The colours may have changed from red to blue (Budweiser to Copart) at Kenny Bernstein Racing, but the objective never alters. The objective is to build bullet-proof engines that can go down the 1000-foot dragstrip quicker and faster than the car in the other lane. For co-crew chiefs Rob Flynn, Mike Guger and Todd Smith (who came over from Don Prudhomme's Snake Racing after that outfit closed operations at the end of the 2009 season), the objective is to fit the strongest piston...

All of a Flutter

[email protected]

A phenomenon rarely heard of these days, is that of ring flutter. Manifesting itself in the form of unusual wear characteristics and possibly high exhaust gas blow-by, particularly at light load conditions, ring flutter if left unchecked, can even cause pre-ignition/detonation of the incoming fuel-air charge, eventually leading to piston failure. The solution however, is not always that obvious. You may always hear that the root of the problem is all to do with the acceleration and...
