Sounds great Kevin! Really enjoying the build. Guess I gotta do side pipes now too
Peer pressure
Not to derail Kevin’s thread, but Cervini makes a side exit exhaust for the 15-17 non-Shelby cars. Kevin’s looks cooler though.
Sounds phenomenal through headphones, can’t imagine what it sounds like in person.Okay, lots has happened in the last couple days. I’ve been thrashing and not docunenting well - so more story time and less visuals.
So to recap, on Thursday I drove the car for the first time up and down the street. After confirming the drive train worked, I knew we could make our dyno appt today.
We made it to the dyno and I seriously felt like there was a 40-50% chance of things not going well. On my test drive on Thursday, the car was overheating just doing 20 mph down my street. And it makes noises I’m not really calibrated at hear yet (the clutch sounds like a tractor, the gear box sounds like it has rocks when not loaded, etc.) So essentially I had little confidence things would work.
My master Aussie tuner remoted into my laptop at 7am from across the world and my local dyno operator, Josh, began putting the engine through some mild load. Here’s an example of what the first hour or two sounded like
Basically, Josh would target a specific part RPM or part of the fuel table and Jono (the tuner) would make real-time edits to even it out. Not going to lie, she wasn’t super happy under medium throttle In the early day. But Jono is a serious master and a true perfectionist. So he kept at it until he got the fueling perfect. First time we did a ramp pull we made high 400s up to ~6.5k
First pull to 8k and it made made 553 on the first ramp pull with no ignition timing and cam timing adjustments. My previous best with a voodoo was 540 that was with 30 degrees of timing and max effort. Needless to say, I was pretty blown away.
In the end, we landed at 575 whp, 467tq with a bit of cam timing refinements a couple degrees of ignition timing. This is with only 23 degrees, so it’s UBER conservative. There’s easily 600 in this beast with 30 degrees of timing and some lower ambient temps (91 and humid when we were tuning this AM). My favorite part about this line is the relative flat power curve from 7100-8200. This car is always going to be in max power at WOT during shifts. Hell. Yeah.
Here’s a dyno pull up to 8600
Really hard to describe in words how loud this car is. It’s the most violent sounding car I’ve heard outside of F1 or some NHRA stuff. Reminds of trans am stuff. Going to be so rowdy on the race track
I’m going to go to sleep now. According to my watch, I have a 60% sleep debt this week. Time to catch up
That's a lot of RPM! What do you expect for component longevity from the build?
I think he’s primarily Motorsport tuner, so Emtron, Haltech, Link ECU, etc. But feel free to reach out to him. He loves Mustangs https://www.facebook.com/jptuneJust epic Kevin congratulations mate.
I’m in OZ , does this Jono tune OEM as well ? Where does one find this Jono
Am not. Too pricey for my needs. They’re a no brainer if you’re running boost or utilizing a factory build, but they have some big drawbacks for DIY builds - cost for one (about 9k more than my AIM/LINK setup), support is run entirely through them and can be difficult to get, and any firmware changes require working with them directly (Link/Emtron allow a lot more customization through the tuner, so you can work more independently). No doubt they’re the top product when money allows and build requirements require it, but I couldn’t justify it (and most tuners said it was overkill).
I don’t plan to regularly shift that high - probably 7500 normally and 8k when I need it. The 8600 rpm was to see where it would fall off and see if there was a bit more if really needed on a certain track (where you just need that extra couple hundred RPM.
You going to the Chin event in June? That’ll be my shakedownWow, just found this thread now. Look forward to seeing this monster build at CoTA soon.
Thanks! Sounds a bit like a nascar car at the higher RPMs. It’s pretty awesome!
Haven’t signed up, but this does give me motivation to sign up and tolerate the heat. Lol
