GT45 minimum boost?
GT45 minimum boost? Hey all- I know very little about turbochargers but if I lock the wastegate open will my engine run like it's naturally aspirated with more backpressure?
The reason I ask is that I am putting a 6.0 LQ4in an AMC Gremlin. I have l92 heads and ls3
Intake and am planning a cam with more duration and lift than the hot cam so it should b 500+ hp.
I don't really want to waste the time and money running y pipe and exhaust tailpipes to the back when it will be ultimately a turbo setup with my gt45.
If I run the manifolds forward can I use the turbo as a big muffler to start out with and get it running by locking my wastegate. I am not kind of afraid what it will be like with boost and ls3 6.0 in such a light chassis and figuring out
the tune and water injection could take a while. I am not even sure how I am
Going to get the motor in yet (adapter plates/oil pan) and then figure out turbo drain and feed.
a while.

If you are dead-set on such a weird build approach, weld up a section of pipe between your turbine inlet and downpipe outlet locations as mocked up by the actual turbo. This will save all the potential damage you could do to an expensive turbo while you are not actually using it, yet allows you to fab up the entirety of the hotside while remaining N/A.

It does a much better job on the 4.8 and 5.3.
Once you add cam and heads to that 6.0, its going to perform even worse.
You need more turbo.
