The old LS1 with over 100,000 miles still has a good leak down, but 20lb it would not like
The low boost is because I have empathy for the engine and so wanted plenty of cfm per lb of boost while still spooling full boost by 3000rpm.
I get boost starting from 1800 (converter stall is 2800) - so it is perfect. Any more and it'd all go up in tire smoke. As it sits I can throw the keys to my partner even in the rain and know she will be safe. Try driving a high boost V8 auto in the wet.
The key to keeping a boosted big engine safe in the wet is intelligent diff (Harrop Tru-Trac for me, but a Quaife is even better), a stall converter (mild for street) to soften part throttle (remember big engines make massive torque at low rpms), a boost gauge to read what your right foot cannot feel, and a progressive throttle (1st 50% of movement might be only 25% throttle). Low boost makes it even easier.
A manual is easier to keep off boost than an auto
