We are not into
Cat or Detroit in Europe so I cannot comment on that al do we have customers running them. Main engines we are tuning are Volvo Daf/Paccar and Scania for motor sport applications.
We also have restrictions as for the Semi pulling sport a max RPM limit of 2900Rpm is there and for truck racing a 65mm air intake restrictor is in place and we can not run compound turbo set-up so knowing this you can build with OE stuff and lower budged so chance is more team on the track and same amount of fun. This game is all about being smart staying within restrictions given and latest generation engines have proven them selves so far that they have more potential but also pose new problems that need to be solved by thinking outside of the box and that makes it fun pioneering along.
The only project with no restrictions was the drag race Volvo in Greece but staidly they had to come down in power ate the AT could not handle the engine torque but they got there own dyno and know how to work things out so wait what they come up with next year.
Leiffi you know as well as I that an ECU on it self dos not set limits on power output and that’s up to the hardware restriction on the engine……..and drive train.
Also the XPI we are working on is race engine with a restrictor 65mm so no point to try making 110Hp per litter as you never get there so focus is to get the engine to 5000Nm + in low RPM and make a flat HP curve as long as possible.
Also we are already past 120Hp per litter on PD engines but they need a bit more RPM compared to XPI or F2 fuel systems to get to 3000Bar +
Leiffi please remember for power you need RPM and as we can not make some RPM so our focus is on torque, get it? And please let me know what people you know as most will ignore you any way. Thanks to you some pore gay is now stuck with an engine wit piezo injector having to spend some time to explain things. You are a great help!
