Hey everyone I'm home sick today and thought I would worry about my car some more.
I drive 88' 745, b230ft, t cam, m46, lh2.2, td05-12b up to 11psi with an mbc. Newer tune up, newer fuel pressure regulator, recently cleaned injectors, O2 sensor reads 0.12V-0.88V, timing at idle is dead on, few months ago confirmed in tank pump was working while replacing the submerged fuel hose, running a genuine n/a main fuel pump in good condition, newer fuel filter and fuel sock. Haven't checked fuel pressure. Engine is also pretty worn out with lots of blowby and over 258K miles.
I've noticed something lately while running through the gears more aggressively than I normally do. At 3500 rpm and above the power seems to hit a plateau. I would think that this range of engine speed would be where the power wakes up. I know torque might start going down but hp should be picking up right?
Am I looking at a boost leak? When I installed the n/a main fuel pump I was told it should flow plenty for my application, maybe I need a turbo main fuel pump? Something else I'm not thinking of?
Any help is appreciated. And this isn't my biggest worry right now but thought I would ask
