Breaking in a new motor with turbo setup

When I put my new motor in, I don't want to be running boost on it at first. Can I just install all my turbo stuff and leave the wastegates linkage disconnected?
Right now the poor turbo stuff is just hanging up in the air waiting.

i would think if you disconnect the wastegate linkage it would allow maximum boost. i wouldnt see a problem with just running the turbo's just stay easy on the gas and you shouldnt see any boost at any rpm.

I mean the actual linkage to the internal wastegates. That will allow them to flap open so you should not get boost. This set up starts spooling really easily. I am sure that I would do something I would regret if the turbos were operational.

I broke my motor in on the engine dyno with boost. I have about 9K miles on it now with perfect compression and less than 1% leakdown in every cylinder, I just checked both when I changed my oil. I've had better sucess with a hard break in than I have a soft break in for boost motors.

Sounds like what some of the turbobuick crowd does, just lock the WG actuator arm open (unhook the arm from the actuator and push the rod out all the way, locks the puck at full open). Your WG is a lot different, so not sure how to do it but it should work once you figure it out.

1000hp-That sounds tempting but since I still need to do tuning on my setup, it makes me even more hesitant. I did have really good luck with a really hard break in on my 97 GT (no break in at all-the car had 142 test drive miles on it new) still going strong at 272,000 miles.
Torque-I can unhook the rod from the arm and then wire the waste gate arm open. Actually, the moving exhaust should keep it open if it is not connected to the rod. You have a nice variety of vehicles.

I agree with 1000hp. Set it up for a real conservative tune to start with, take it out, and stand on it.

Well, whatever happens, that engine has got to get here first! Supposed to have been built last week but did not hear anything so it is probably not finished or started.

just shove a screwdriver into the exhaust blades, shold keep them from spinning while you break in your motor.

just hook up everything like normal and break it in. don't floor it for the first 200-400 miles. 1 or 2 psi from driving up hill won't kill the motor.

No, but not standing on it right away can very easily lead to rings that never seat and related problems down the road. There's a web site a guy made up about breaking in motors that explains EVERYTHING in detail, but I can't think of the name of it right now. I know others on here know about it though.

Supposedly even on an NA motor, you are supposed to vary the conditions of load on the motor. Ie getting on the highway and driving 1000 miles is not a good way to break it in. It would be more convenient for sure to have everything hooked up. My flipped headers will be ok for GT40P heads but I have no parts to run it na. I would be curious to see how the motor peforms compare to a the old stocker in NA form. Gotta call them today and see if it is done yet.

Interesting reading that mototuneusa. So I guess that a forced induction motor should break in even better (?). It does seem doubtful that a few psi going up hills or whatever would hurt anything. My tune or lack there-of may. But then again at a few psi it should be ok.
