i was just wondering who all is running twins out there and how your truck is doing heard some guys cant keep the hg in place and i got twins but if everyone is haveing issues im going to sell them and buy a big single all respond please thanks guys

 

I don't have twins, but i do have compound turbos. HX35 over S400, peaking at 57PSI with the 65's now. No head gasket issues with stock head bolts and original head gasket.

 

New here, What is the difference between twins and compound?

 

Depending who you are, everything or nothing. To me, twins means two turbos the exact same. Generally one run off each side of a V, or on inlines you split the cylinders. 1,2,3 for one, 4, 5, 6 for the other. Compounds is one turbo feeding another. Diesel did a write up on the differences, and sadly enough their editors don't practice what they preach.

 

i was thinking like redneckpipeliner ya i guess i will be running compounds hx40 and ht3b i have got arp studs and will be running a new gasket (not a factory gasket) and o rings when i get the truck back its in the shop right now (3rd head gasket) is this on a 6.7 or your 01 thanks for the input keep them coming

 

6.7s are having trouble holding a gasket. i have saw guys running 625s but didnt hold one. one guy i know local cant hold one with compounds. a after market gasket might do the trick.

 

6.7s are having alot of trouble holding the gaskets with compounds or big single turbos, pretty much the only fix i've seen is to fire ring it but then your replacing the rings every 30k miles or so if your street driving it. i havnt tried it yet but i have a theory that if you fire ringed the head and block that it would hold on the street because all of the failures i can think of that i've seen pics of were head only fire rings so half of the ring dosnt have anything holding it in place and lets it expand and contract and i think thats what breaks them

 

the gasket+o rings ill be running is the same as tripple compounded tractors and top fuel dragsters run i dont know i want to ditch the vgt but i just dont want to be steadily popping gaskets and the twins i will be running is a smaller set i think to what others are prolly running and on the fire rings i just dont want to have to keep taring it down to replace rings if you know what i mean unless maching the block would help like you said and dieselpap is he running a factory hg
