Biggest street turbo? Semi turbos? :)
 

Is it still the T88 or is there something thats bigger as far as maximum spool goes? Does anyone know how much boost those twin turbo diesel semis are running?

I just heard one today that was a dump truck, pulling a hell of a lot of coal and god damn those turbos sounded awesome :).

I'm not looking to put one of these on my car just really friggin curious :)

I dont know about the size but the other day I asked the driver of a cement truck that delivered a load to one of my jobs if I could see his engine and I creamed my pants!The intercooler was polished,the charge pipes were chromed as well as the cool side of the turbo,but that dam turbo was HUGE! I mean that had to be the cleanest set up on a rig I have ever seen.Im always aking different guy to pop there hoods.Those guys take care of there ----.Some times while they are unloading and they get a break they pop the hood and dust off the engine.I guess you have to keep them up when they cost 90-150k dollars new :o
