What size pulley did you get? Stock airbox?
People talk about the rods being weak, how many have actually seen them break on a 5.0?
The pistons are another story. the rings seem to break, or the piston just completely falls apart.
Oil pump gears are also a major cause of failing. Most of the guys running it up to over 700 are using Billet oil pump gears (like myself). Install on those is between 7-900, it is a 10-12 hour job.
These motors seem to be all about the tuning.
I wish I knew the answer to this as well because I am itching for another round of upgrades. I have a Roush TVS, 79mm, VMP tune, and I want MOAR! I am too scared to push it any further because I don't want to deal with an expensive disaster.
How many people are running a TVS with more than 10 lbs. of boost and more than 600 RWHP? I'm not sure how safe I would feel adding another 2 lbs. or so of boost.
^Exactly D.T.R. It's all about how the power is applied. Like I said earlier, a twin screw blower is probably the worst case scenario for the rotating assembly. You have instant boost and torque right off idle as opposed to near linearly increasing boost and torque on a centri or turbo. The low end smack in the face the rotating assembly receives from a twin screw is much more harsh than boost ramping up through the power band on a centri and turbo setup.

What do you consider "big power"? Most seem to be keeping it under 600 RWHP. Do you think problems are going to start creeping up for all of us at those levels?If you put big power out of these motors it's not a question of if, but when you get to build it.
A lot of people have gone over the 700whp mark and lived to tell about it. one guy on here with a procharger is making around 720whp and has not had any issues that I know of. If you have a good tune and dont spin it to 7500rpm it should live. Unlike most people I am keeping my stock redline. There is no sense in spinning the motor 700rpm higher than stock, that 700rpm makes a HUGE difference in the life span of your rods and pistons when your power gets that high.
