…race car?
.. well I’m sick of the wall of blue behind me, so I pulled the turbo and sure enough, it’s leaking oil past the seal into the turbine housing. No oil in the compressor housing. No residue in the wastegate/turbo manifold/dump tube. Definitely sad panda…
Let’s see if Comp steps up and addresses the issue.
Head lift at 19-20psi and pushing coolant… that’s how. Had to tear the top end down and torque those head studs down like a boss to keep the head planted. Turns out ARP stud specs aren’t sufficient when you’re pushing 700hp.
Time to mix up the boost control… 4 port MAC solenoid and 3psi/5psi WG springs.

…. ruined my dyno day. I did hit 380 ft lbs to the wheels before my engine bay turned into old faithful…

Cleaned up the injector harness a bit… see before (first) and after (second).
No more getting yanked from lane to lane…
Well we found my 4th gear engagement issue… 4th gear syncro was worn to hell, even though it was brand new… Stock syncro going in now, 4tw.
OEM syncro is on the left, Gearspeed 4th is on the right. Note how it’s completely worn off… We also have the tranny masta at work.
