Brands Hatch last truck race weekend of the year 2019
Normally you do all your upgrades during the winter break but no we where there early this year able to test them last weekend on Brands Hatch.
So what have we done? B division trucks. Slam some bigger injectors into the D13 Volvo engine and gain some more power the easy way.
Bint racing with there very old and heavy but bullet prove Detroit 60 series engine still makes loads of power but best way to explain how is bigger is not better but this has a load to do with the cam profile used in these engines and how to set-up your injectors.
A division trucks. Well gain some lose some. Scania engine we testes some things on the fuel system. Point is it works well but now the engine spools the turbo so fast and hard as we now run short of fuel form low to top end and the truck it self gets harder to handle dos not provide the stability to put all this power on the tarmac. Bigger picture for the Scania engine is that we are well on our way to build a new rally truck with a Alison 4000 gearbox and yes do not think this AT can handle the toque well of the Scania engine but turning power down is a lot easier than making more power and plan is to run the AT with the lockup on all the time giving it the feeling of a MT gearbox so fast turbo spool-up will be great to have.
MAN D26 engine. Sometimes you discover new things as a simple switch not active of connected and when this dos work the clutch is unable to hold the engine torque so you run of pole on the starting grid ending up 3e place on last race. But yes told the customer to use an upgraded pressure plate on the clutch. Must say some of the engine management systems and engines for A division trucks are complicated. There is a lot of driver assist things you can adjust with switches helping you to reduce power per gear for example so for most race drivers it takes time to adjust to this finding out what setting work best for them sometimes even running on a lower power setting without them knowing so that’s where data logging comes in so you can find out and tell the driver what to do or next race. Essentially every A division team should a have a race engineering for driver support on and of the race track telling him what to do.
