By disconnecting the manifold signal from the WG actuator, have I ruled out a misadjusted or weak actuator as the cause of lower than expected peak boost?

+/- 14 psi surge / leveling off at +/- 12 seems go be about it. I tightened the actuator push rod adjuster three, 360* turns, shorter with no change. At some point, adjusting the MBC netted no change.

Maybe this is the peak performance of this set up. If so, I am happy with that. It runs great.

Consensus is that the current WG actuator does not have the spring to hold the flap closed at higher boost levels. Done pouring money into the abyss for a while. Going to dyno at +/- 12 PSI on the 13th. It is what it is.

Spent my recent evenings chasing the oil leak. The under side of the car is coated with oil: trans crossmember, exhaust, axle. Meh. Replaced an O-ring, crush-washers, oil filter, snugged up a few fasteners. Hosed her down with cleaner for the 100th time. Been chasing this bitch for a year now. ****, ****, ****.

Son and I are doing a 1,000 mile road trip to south eastern Oregon next weekend. Should be fun. Despite traveling for work, I've never seen this area.

Bought some eCode stuff. Pretty excited. Well, gotta spend when the deal is hot...

Throw a manual boost controller on there

Got one. Even disconnected the boost is less than expected.

Probably for the best with an M47.

I added 3 x 360*. Looking at ATP actuators.

But even with a 5-7 lb spring the boost controller should allow it to hold off more then snap open quickly. Maybe bad MBC. I went through two before I got one that worked.
Weird...

I need to learn more about the relationship between actuator spring pressure and resulting boost pressure. Not sure what the stock actuator spring was VS my current aftermarket unit. It's a fun conundrum finding the sweet spot for the actuator spring pressure and the MBC adjustment.

Pretty sure my breakerless / 2.2 combo could handle 28 psi...

Gotta have the tires balanced before the big road trip next weekend. Got my tool kit laid out. Makes me a little nervous going that far off the grid. Should be fun though. One of the passes is 6,200 feet. Hope I don't regret not bolting on the snow tires.

Beautiful day for IG pix.

What components trigger the LH2.2 rev limiter (at +/- 6,000)?

007 air flow meter? Other?

Is this all she’s going to do?

ECU and EZK both have limiters. You can increase the ECU limiter with a chip but I dunno about the EZK.

Both can be increased with a chipped ezk, preferably you put the ezk limit a little lower, for a soft ignition cut before the hard fuel cut

Did it do the limit at the same rpm before?

This rev limit condition is new to the current set up. I had never seen this “Bah!bah!bah!” at 6k before. Part of this may be that it now loves rev.

Engine still leaks oil. I may not be up to this. Think I could get $4k for it?

So you never got on it before the turbo?
The noise sounds like a rev limit and won’t change without tuning the map.
That said, it could be something else and not rev limit but I don’t know since my stock 2.4 limit was also ~6000

I’ll buy it for $500 tho. Let me know.

Thx boss.

The old turbo was "done" by redline. This one wants to go.

Just need to throw another $3k at her for EFI and transmission upgrades.

Leaving on three-day road trip tomorrow. Chicks dig fast 245's...
