Phat shaft 62mm ??
Hey Im thinking of buying a used Phat shaft 62 mm silver series turbo. Was wondering if it will be enough for my mods ? I have a 06 5.9l With 90 hp sticks, edge w/attitude, intake,dual 4" exhaust, bd intercooler, bd trans, Im looking to hit the 550hp mark . Will I get there without overly high EGT's ? What boost # will i see , Im hitting about 43 psi with stock turbo and running around 1400 degrees at wot.
Thanks |
First, you say Phat shaft and silver series. Which is it? Those are two very different turbos. (There is also a super phat shaft) The turbos are mostly differentiated by their turbine size. The phat shaft is a 65mm turbine. The silver 62 uses a 74mm turbine.
Assuming you are looking at a silver 62, yes it will handle 550 no problem. Expect a fair amount of lag over what you are used to seeing now. EGTs will be lower at the top end, but a little higher at the low end and cruising. The silver is a high performance top end turbo... not a towing turbo. Boost #'s are a little irrelevant in this comparison. What you get is dependent on fueling too. Expect to see, in your case, about 45psi. But it is a much different 45 psi than the stocker and that is why the egts will be greatly reduced. It is due to a much more efficient and free flowing turbine and a denser/cooler flow of air. Even though overall boost is close. |
