Just to increase my general knowledge of trucks, I´d like to ask what is the reason for using twin turbo set up on a diesel engine instead of a single turbo. I am talking about the in-line engines, especialy the old Cummins that´s privided by RoG in their American truck kits. Two smaller turbochargers have probably quicker response then a big single turbo. Was this the reason? Do the two turbos increase the power more then just a single one? Can anybody shed some light on it, please? Thank you

Thank you Jarda im going to go non truck related here but forgive me but the twin turbo was nothing but a small turbo (pre) and the larger (main) if you find one mazda rx7 that was a twin turbo equipped rotary engine the smaller (pre) wound everything up a bit faster and thats why everyone that runs turbos usually has a small preturbo somewhere (in racing specs). thats the best way for me to explain it so if anyone else can explain it easier than by all means...!

Hi all
that is totaly right but I have to say that I didn't know that they use that system on trucks too. For normal diesel cars here in Germany you have that type of turbosystem to have the so called turbo power from the beginning on and not only from 2000 to3500 rpm. You don't have the so called turbo gap on that cars.
so long Arnd
