    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...

    CT4 V Blackwing Carbon Fiber Drive Shaft

    Bump because I want this thing and am impatient. See? I made it more than a month before being pesty :)

    CT4-V What modification won't trip the CEL?

    When the carbon fiber drive shaft comes out for the cars that'll be something that causes no CEL and has a noticeable performance bump. Shouldn't screw with your warranty either. Hard to argue something causing less stress on the system caused an issue. Plus with the trans being so stout it...

    Anybody swapping tires/wheels for track days? TPMS question

    Swap works great on my 4BW. Sensors in both, about 30 minutes later it recognizes when I've swapped.

    CT4V BW PPF - who has done it, and what panels

    Did the front half and mirrors. I think I'm going to get the rear quarters done as well since that's been an area I've smacked a few cones. No damage so far but I know it's just a matter of time before there's a scratch. Funny thing the rear just seems to step out on its own like it wants to...

    CT4 V Blackwing Carbon Fiber Drive Shaft

    I'll be looking forward to that day. One of the few mods that seems unlikely to cause issues with warranty that should have some noticeable impact on performance. Anything to up the agility on the 4 which already seems supernatural given the size/weight of the car. I stand by it feels more like...

    CT4 V Blackwing Carbon Fiber Drive Shaft

    Anyone have some news on the production of a CF driveshaft for the 4BW? I know the ATS-V had one available so I'd *think* it wouldn't be too much of a stretch to get that changed slightly to fit into the new cars. With the high power of the unlocked ECU's seems like that'll be something that's...

    Tapout CT4-V Blackwing Carbon Fiber Intake Test Results

    Mine is heading back to TapOut. I'm not entirely sure I'll buy into revision 2 (if it appears) if I get burned on shipping both ways. The ever evolving story from no CEL... to some few people... to any time it's cold. It's certainly moved me to the wait much longer and see camp.

    Tapout CT4-V Blackwing Carbon Fiber Intake Test Results

    So from the testing this weekend, my garage stays a bit over 60 degrees and after multiple clear cycles, it's still showing up even starting from the garage each time. In response to why the lid instead of the JB4, it sounded like a CEL free way to get some extra horses and looked more or less...

    Tapout CT4-V Blackwing Carbon Fiber Intake Test Results

    For me it was in the 40 to low 50 degree range that it popped on. Going to give clearing a try and a few starts from my 60 degree garage and see if that keeps the codes away. If not I'll be removing it and returning until there's a fix. It's not worth possibly losing the warranty over. Kills me...

    Tapout CT4-V Blackwing Carbon Fiber Intake Test Results

    I will also say this would be way less of an issue if it wasn't secured with a thousand screws and one is a total pain to get at. Does GM hate people that change the air filters regularly? I don't see why this couldn't be done with clips or something. With how much crap I had in my airbox I'd...

    Tapout CT4-V Blackwing Carbon Fiber Intake Test Results

    Got mine yesterday and third drive today got a CEL. I'll do a bit more fiddling around to see if I can figure out anything more. If it's a winter/spring only think I can probably live with it. I've got the tools to clear it so we'll see if I can find more specific info. Interestingly, I had...

    Tapout CT4-V Blackwing Carbon Fiber Intake Test Results

    I'll be curious what the results are. I'm above a mile here and will likely be getting mine dynoed before/after the change as well. With as much headroom as the turbos are described as having, it should have similar results as our sea level counterparts. Finally found a source for 93 octane!

    Took the plunge! Hopefully I don’t see the dtc. It’ll be interesting to see the results.

    Tapout CT4-V Blackwing Carbon Fiber Intake Test Results

    I'm dang near a purchase just on looks alone! You're completely right there. Sounds like it really does get us a good chunk of extra zoom. I don't doubt TapOut but dang is that a lot of horses for an intake!

    Tapout CT4-V Blackwing Carbon Fiber Intake Test Results

    What was your peak boost prior to install? I'm guessing around 12 and you're closer to sea level? Thanks!
