  2. Need some feedback on my density altitude app

    LOL thanks! I was worried there for a second lol. Hope you continue to find it useful!
  3. Need some feedback on my density altitude app

    Plugging in those numbers here does return just over -3000 ft DA https://wahiduddin.net/calc/calc_da_rh.htm But you're saying the weather pulled in doesn't match the actual weather? I did a test for these coordinates (somewhere in Winnipeg) and got a current DA of around -2008 (might have...
  4. Need some feedback on my density altitude app

    Hey guys, next time you're out on the drag strip or out racing somewhere, or just curious about what your current DA is, can you check out my app and provide some feedback? https://play.google.com/store/apps/details?id=com.appjumbie.www.streets_da Basically let me know if it's useful or could...
  5. Going Ported Cobra Jet manifold on my 2018 Mustang GT A10

    Yeah mine is ported from Brett Barber also. With good E85 the car pulls hard. Even in 85 degree weather here in Florida. Shit, it pulls hard even with 93 octane on the 93 tune. Don't think there's anything else I can do to make it faster naturally aspirated, other than weight reduction.
  6. Going Ported Cobra Jet manifold on my 2018 Mustang GT A10

    I wouldn't do anything else to it at this point, it's pretty much where I want it to be naturally aspirated. Personally the only logical next step would be to throw a centri blower on there, but I would rather use the money for that used as a down payment towards another car, when I reach that...
  7. Going Ported Cobra Jet manifold on my 2018 Mustang GT A10

    Yes, I wanted to wait a while before reporting, in case any issues start creeping back up again. Basically after taking apart the intake again, and taping up that exposed wire, car is back to what it was. I didn't even have to install the JLT CJ intake, but I'm keeping that as a backup. I have...
  8. GT Ford Racing Cobra Jet CAI

    The JLT airbox for 2015+ is no longer available, so this is only for 2011-2014 GT models. You can still make this work on 2015+ cars if you find another airbox that fits those years. Taking it off the description and dropping the price to $200 shipped.
  9. 2018+ With CJ manifold people. Lets see some time slips

    You should feel a noticeable difference from 6000 - 8000 rpms, where the CJ really shines. If not something is wrong with your setup. A CJ on an 18+ is not a straightforward plug and play, it heavily depends on the tune and what you have done. This is also one of those setups where no two cars...
  10. 2018 GT A10 Power Band

    Why are you quoting me from back in August? You should read my threads and posts more often.
  11. Going Ported Cobra Jet manifold on my 2018 Mustang GT A10

    So I just came back from disassembling the entire Steeda intake, cleaning it inside out, wiping the maf sensor with a soft cloth, etc.. when I noticed this (see photo). I wonder if that was responsible for the maf codes I was getting. So I put a sliver of electrical tape over the "wound", then...
  12. Going Ported Cobra Jet manifold on my 2018 Mustang GT A10

    I have the worst luck, it's like anything bad that can happen, does happen :cwl:. Here's my convo with Rob (attached). Based on his recommendations I just went ahead and ordered a JLT intake. I called them and sent me a customized kit for my 2018, including different couplers and clamps I will...
  13. Going Ported Cobra Jet manifold on my 2018 Mustang GT A10

    Just wanted to update that I'm still having issues with the Steeda CJ intake. The dying at idle issue actually came back, but not right away. It kinda snuck back in slowly over time. Now, I'm getting maf codes (P0103) - Mass Air Flow MAF Circuit High. When this comes on the display showed a...
  14. What's going on with Palm Beach Dyno?

    Is that within the last week or so? Trevor is who I am working with, I havent had a response to my email a month ago or to the one I sent on Monday. I also sent an email directly to their support system, crickets. You only get a confirmation email the first time you reach out to them, I'm on...
  15. What's going on with Palm Beach Dyno?

    Not responding to my emails, communications were great last month then abruptly stopped. I call the shop and they're closed?
  16. Going Ported Cobra Jet manifold on my 2018 Mustang GT A10

    I did a second pull after that and it went straight to 498 hp without any spikes, after a 2 minute cooldown. Forgot to take a pic of the second pull, these guys don't do printouts. Not gonna nitpick about numbers, but 500 plus or minus seems to be inline with the other CJ A10's running around...
  17. Going Ported Cobra Jet manifold on my 2018 Mustang GT A10

    Yes the tubing is noticably larger with Steeda, it flows significantly more, and it's a closed intake so no crazy spikes in IAT's. I was told by my tuner that the ford performance CJ CAI would potentially be a restriction for the CJ manifold on the 18+, this looks definitely to be true.
  18. Going Ported Cobra Jet manifold on my 2018 Mustang GT A10

    Car feels really strong now. So to recap: 476hp with stock manifold (plus long tubes, xpipe, E85, JLT CAI as starting mods) 469hp with ported stock manifold and ported oem throttle body (yes it made less) 489 hp with CJ manifold and VMP 69mm TB and Ford Performance CJ CAI 502 hp with...
  19. Going Ported Cobra Jet manifold on my 2018 Mustang GT A10

    I was able to get the idle issues worked out. I'm not sure how or why it happened. It's been many days of frequent driving, it doesn't idle erratically at a stoplight anymore and eventually die, which is a good thing because that would suck being in traffic lol. I also went back to the dyno...
