POS threw some code so I threw it into the garage for winter and will look at it next year.

I drove it to work :driving:

Hope it doesn't rain because it doesn't have any windshield wipers installed right now :ugh:

Also spent some time the past few days trying to figure out a noise. Fairly certain it is the exhaust making the noise. Hope to data log a little bit this week to send to Seb for a retune :tup:

Lipstick and kneepads? :nutswinger:

Have a spare set?

Does the noise sound like.. exhaust?

Do you need lipstick too, or are you ok there?

Nope. It almost sounds like the damn throwout bearing (which is brand new) :ugh:

It happens around 2.5K RPMs. Can be engine braking in gear. Can be stopped in neutral and give it the right amount of throttle to make the noise. It happens briefly during gear shifts, too. Would be annoying except for racecar! Plus during the gear shifts it kinda sounds like a blowoff valve for my poser turbo :icon17:

That sounds like good old test pipe hiss lol

Welp, Smoke test saw leaking out of the passenger side exhaust, something is up with that side of the valve-train or cylinders. I did notice that I've always had a light oil haze on one side vs the other in the past when cleaning the lower manifold so that may not be the leaning issue (I'm never burning a ton of oil between changes). He's gonna check the fuel pressure to see if that may be it.

When they tested it. The engine may have one cylinder at valve over lap. Where the intake and exhaust valves are both open. Crank the engine over and do it again.

That's what i'm thinking. with the frequency of my oil change intervals (and checking the dipstick on fillups, i doubt this IS a problem. I'm gonna let him test the fuel pressure and FPD and get back to me. we did confirm that my connections and hoses are all not leaking so that is a good thing. If the fuel pressure comes back ok, ill look into getting the injectors cleaned/replaced. Pulling the plugs should tell me which ones are acting up, unless it's all of them lol.

Yup. I just haven't really heard it like that in a Z before. I'm running FI test pipes with non-resonated FI exhaust with CF cans. I wonder what FP's straight pipes sound like.

Flacid, buy a new Z and sell me your axle-back straight pipes so I can test it out lol

Talked to the shop today. It sounds like I just need a retune. Fuel pressure was tested at 55 psi, so Kevin is gonna swap out my motor mounts and I'll pick it up sometime next week.

I'm just glad nothing catastrophic is wrong with the car. I'll probably throw some new injectors in and get it retuned.

When you drove mine, you didn't hear the hiss?

Sure did. It's not even remotely the same. I'll do a video of it one of these years.
