Default Update: Boost issues...

So I replaced the N75 today, and relubed the Forges while checking for leaks. I had replaced all the braided hoses with silicone a while back.

I think the problem was the N75. The following graph, compared to the one that I posted on the 15th, is looking a lot better. The temperature during the run was about 74 degrees. Colors on the graph are identical to the original:

I ordered the appropriate parts from McMaster for the pressure tester and will be doing the test next Saturday. I'll keep the original thread updated.

Thanks!

You are still spiking between shifts, though?

Default Yeah...

I think it's the Forges. Right now, I have the green springs in them, but I really think they just aren't holding pressure anymore.

Next Saturday, I'm planning on pressure testing the whole system (with the parts from McMaster) and then VAGing with new 710s.

I'll keep the original thread updated, as well post a new entry on the forum.

Honestly though, compared to the graph that I made on the 15th, I think the car is in much better shape.

Default Ultimately...

I think I need to do better VAGing through at least two gears (ideally 3rd and 4th) to make sure that everything is working well. I'd like to see at least two gear shifts just to make sure that she's not spiking.

I'll keep the forum posted.
