    4 Blackwing Gigs Throttle Body Install

    With increased airflow I'd imagine it'd be even more pronounced is my guess.

    CT4 V Blackwing Carbon Fiber Drive Shaft

    Carbon Fiber drive shaft in with the differential lock out bushing: I was going in expecting a bit of a change. Maybe nothing noticeable until winding the car fully out. I was not right about that. Coming off the clutch is noticeably smoother without having to pay as much attention. Seems the...

    4 Blackwing Gigs Throttle Body Install

    I think that depends a bit on your personal risk aversion. If you give no... ducks... about warranty, a tune will probably get you more bang for the buck. If you're aiming to tune the car with a bit more edge and power within the bounds of being unlikely to lose your warranty it's 100% worth it...

    CT4 V Blackwing Carbon Fiber Drive Shaft

    Thanks! I was wondering if it might just be an accidental auto selection since there wasn’t an explanation. You guys consistently provide good info on why a mod is an improvement.

    CT4 V Blackwing Carbon Fiber Drive Shaft

    Quick question for @WONT TAP On ordering the CF drive shaft, I see it comes pre-selected with ATS-V shifter bushings. Is that a known upgrade for us Blackwing people? It was common practice in the Porsche crowd to move to GT3 shifter bushings as they were billet aluminum instead of plastic and...

    CT4-V Boost Pressure

    I'm always gentle during warmup which means it never sees more than 6 lbs of boost until the oil is close to temp. Probably overkill but who knows.

    P30EF-00 Code

    Haven't had something like that on my Blacking but in the past that usually indicated too much resistance/voltage going to the fan to spin. Our cars may be more advanced and have a separate sensor but either way sounds like replacement of the sensor/fan assembly under warranty is your best bet.

    4 Blackwing Gigs Throttle Body Install

    Looking at the difference between the two throttle bodies I am completely unsurprised by the gains. In all the Porsches I've owned in the past the throttle bodies were clearly polished. The stock one in our Blackwings (mine at least) the entrance was still clearly just cast. No cleanup...

    CT4 V Blackwing Carbon Fiber Drive Shaft

    Haha, fair enough! Sounds like Texas has a great Cadillac scene. New Mexico not so much. I may have mine in about the same time you get yours in that case!

    CT4 V Blackwing Carbon Fiber Drive Shaft

    @JB5359 What do you think of the CF drive shaft? With how well it seems to be balanced and setup I'd expect even less NVH coming through. Any other things you've noticed, good or bad? I'm about to pull the trigger and thought you might be able to provide us some insight. Lesser designed one...

    How goes the testing? Hoping to have one fitted before the autocross season gets under way lol

    4 Blackwing Gigs Throttle Body Install

    Quality water heater installed instead of the garbage whirlpool the house came with. Yay! Anyway, got some time with the new throttle body in and everything plugged in right. While it isn’t perfectly scientific, I got to do some 60-90 pulls with my gps running. It is t the fastest gps but still...

    4 Blackwing Gigs Throttle Body Install

    Replacing my hot water heater this morning but I’ll have her out this afternoon to see what it’s like. I can already say the throttle tip in is a good bit sharper until the boost fell off. Feels a bit more similar to cars I’ve owned with ITB’s than previously. More direct throttle action? Which...

    4 Blackwing Gigs Throttle Body Install

    Close! It was the line on the passenger corner of the vacuum assembly that wasn’t seated right. It was making me crazy! You got me on the right track. Thank you! The one hidden behind the one mentioned. Hallelujah!

    4 Blackwing Gigs Throttle Body Install

    Got the drive cycles done and no more codes! Still reporting 6 lbs of boost but it feels quick so I’m not sure what’s up with that. I’ll dig around and make sure I didn’t make any other mistakes. Car work and sleep dep aren’t the best combination. I should really remember that at this age...

    4 Blackwing Gigs Throttle Body Install

    Okay, so I had some time to get the throttle body installed on an otherwise stock Blackwing and figured this would be a good place to chronicle the results and one dumb issue in case anyone else runs across it in the future. First bit to note for anyone installing, the quick connects for the...

    CT4-V Factory LF4 Wastegates - Spring Pressure and Thread Pitch

    I'd certainly be interested in an upgrade like this. Tell me more. Direct bolt on? It sounds like it. Better response would be great as I've been running autocross and any little bit of boost to on/off throttle response is worth valuable tenths for me lol. Any idea if it's going to tick off the...
