C15 BRIDGE ENGINE
 

I had a 550 Acert before, didn't like it, now I have a 01 C15 550, pulls good with the wastegate hose pinched. I will be in a 550 bridge soon, what can I expect for power? cpu regulated wastegate, catalytic mufflers. What else can you tell me?

They're yellow... don't pinch off the line.

I just started to move into my new ride, found out it's an 03 C15 :lol: Last year of the good ones! What did you mean Bob, when you said not to pinch the wastegate hose? P.S. Cat finely has a fix for the rocker arms! only took 5 years.

blocking waste gate actuator hoses will cause the turbo to; overspeed, overboost, and self-destruct. the cause of the failure is easily determined and voids engine warranty.

NAH, your s*#ting me... They just run cooler pyro temps, more pollution. I haul in the bush, no city driving.

how much boost? how low do you lug it?

cooler pyro means lower NOx emissions.

the problem isn't manifold temps or pollution - it's overspeeding the turbo.


'03 still has warranty?

Warranty, ? 11000 hr's I don't lug too much, 18 speed. Sometimes I have to lug to get over the top of a hill "barefoot" about 37 lbs boost, set at 550 hp. I just got into this truck... normally a 550 is about 30 lbs boost. I've seen my pyro at about 1150 :shock: lugging, 850 whith the wastegate pinched. ???
