Help! I am putting on an HX40 turbo in place of my HX35 and was warned that I might burn my pistons up. With more air, I will lower the EGT, but the actual piston temperature may rise - and the excess oxygen in the cylinder will burn the pistons. Is this a load of poop??? I was changing to...

HEMI Thanks for the reply. I've got this motor in a boat - see previous post. Anyway, It has a homemade exhaust manifold that mated up to the hx35. You answered my concern - it should match the exhaust manifold. The exhaust pipe I'm not sure of though - sounds like I need to make some changes...

What are the safe limitations for continuous running conditions for this motor. -EGT (before the turbo) -RPM's -Boost pressure (I have the HX35, but am installing the HX40 soon). Also does anybody know where I could get insulation that I could wrap around my turbo? Thanks, craig

I've got a new turbo on the way to replace my ailing HX35 turbo. Does anybody know if the HX40 turbo will bolt up without any modifications to my exhaust system?????

Sound advice - A friend of mine reccommended the EGT gauge a while back - I installed one with the probe just in front of the turbo - unbelievable temperatures - normal, but I'm just not used to seeing temps so hot. I run it a 1100F while cruising out the fishing grounds (5 hours) - I've heard...

Joe/PSInt, Thanks for the responses. I need guidance on what I should invest in to increase the HP a bit - for this boat application. By the way Joe, the boat is a typical East Coast lobster hull 34' long. It is considered a semi planing hull. I recently changed the gear reduction and the prop...

I've been reading for a while the vast knowledge on this forum and finally decided to join because I could use some good advice/help. I have a 180hp 5. 9 Cummins from a 1997 Dodge (CPL 2022, manufactured 2/15/96) in a commercial fishing boat. I didn't have the funds to get a new Marine Cummins...
