When the injector duty hits 131% i think we have an issue.
So starting with a 34lb injector x 131% gets us to 44.54lbs and assume max duty wanted is 80% gets to 56lbs. I assume they will throw some 60lb injectors in. Will find out today.
I believe Craig was going to raise the limit to 8500rpm so i should be able to nudge 8 without it pulling back in prep for hard cut.

Ahh, ok I though it was the 2018+ with the higher compression. Which throttle body do you have?? I would try Shaun at AED with a long distance tune? Am pretty sure he would get you to 475rwhp.

You will have to log the car a couple of times on the road (or dyno if you like), but in some ways I like it better then a dyno tune.
I tried everyone you guys have suggested and no one was interested. The ECU is different enough that they just say its not worth the hassles. A few have said they have tried previously and had issues. Others didn't like my combination of parts and would only do it if i used what they suggested.

I'm in the hands of others so just have to go through the process. Something i struggle with.
 
The Gen 2 head springs are hard no go over 7500 rumors has it they are a hard no go over 7000 rpm.
Ok. Sorry. I am learning more and more about the Gen 2 engine that I did not know. I certainly am not wanting GAR944 to bust his valve train. Lots of Gen 3 and Gen 4 Coyotes are running 8000 rpm.

You are a PP3, though, right? Didn't Ford warranty a raised 7500 rpm redline on the Gen 2 with PP3? I'd think that Ford engineers and bean counters would have built a huge margin of safety into that decision. The PP3 did not change anything in the valve train.

The did rise it to 7500 RPM and I use mine there but still it's on a borrowed time that way increasing it further makes that borrowed time a lot less.

My understanding is that they are the same as the boss 302 springs. Been running them 8200 - 8500 for 3 seasons with a freshen up between seasons.
 
So picked up the car Friday afternoon. Of course it decided to rain and be cold as. Love driving a track oriented car in the wet. Cold everything and no traction. And full open exhaust past a large police station.
The boys did me a little favour and painted the mirrors as a surprise. We had been talking about it before dropping the car off. Its a pretty plain white car.
Asked the workshop foreman what he thought of my car as he gets to drive a lot. I've only ever drive 1 other, not a great sample set.
He like it, did say it scared the crap out of him as he had to drive it when doing some road tuning. He was told to rev it out and lifted at 8000, he was promptly told to go all the way to cutout. He said hearing a v8 going all the way to 8500 was wild.
We know the first tune isn't 100% so was asked to log anything i feel and when it happens. Appears we have some torque limiting going on from 6 to 7500 as apparently it really wakes up in the 7500 to 8500 range. There is more there, just needs to be unlocked.
They can also do some more work on the bottom end now the larger injectors are installed. Once it gets tweeked we will get another dyno run done for comparison.
Over the weekend got to start modifying my bonnet vent. That manifold sits high.

You probably already know this, but Steeda sells engine mounts for the S550 that lower the engine height. They used them on their own "Silver Bullet" naturally aspirated drag car with that intake manifold to get it to clear the hood.

You probably had to ditch the strut brace to run that manifold, right?
 
It will be really interesting to see how this all goes once you get the final tweaks on the tuning. What an adventure!

I asked earlier, but is E85 not a thing in Australia?
It is but not everywhere, just another headache to deal with and a revised fuel system needed for the volume required. We have good 98 RON which is your 93 everywhere. My local petrol station used to sell 101 race fuel as we had a dirt bike track nearby. Unfortunately no more.

Actually ditched the brace for the camber plates but it was going to go for the manifold as well. It was really a case of what got installed first.
 
Well the weather is still crappy but i spent a few (a lot) of nights in the garage. Got the modified bonnet vent fully secured. Screwed in this time. Who the hell came up with 5.5mm nuts for M3 screws. Don't think it even lines up with anything imperial to keep you guys happy.
Picked up some aerocatch latches for a good price as i have seen them for proverbial drug money on the internet.

And yes that is how close to the wall i have to park to get the garage door to close. I lust after some of the barn size garages i see some of you have the pleasure of working in.
Debated the first option marked on the red tape but didn't like the amount of curvature the latch was going to have to deal with. Found a thread on here, surprise surprise, and the sideways option looked good and away from my vents.
Now the fun part, there are 3 layers of material at that point. That wasn't fun but it allowed for a nice small hole on the underside. A cutout on the top side and some serious WTF cutting and grinding of the inner layer a few mm under the top skin to allow the clamping piece to fit and be partially wedged to get the screws in without needing access from underneath.
Seriously the first one took a day of trying various things to do the cutting and pulled muscles in my back. Not happy Jan. Pretty sure that's an Australian only reference to a phone directory add. Link here if you are really bored,
Needless to say the second one only took a couple of hours.

Good work! Just a small note…
Keep an eye after a few track days on the striker. The red ones are aluminum and I’ve seen them bend. If it does it may benefit you to swap out with the steel one
 
So bonnet is now secure and all parts attached. Weather finally decided to be warmish and no water. First drive after bringing it home in the wet. Short drive down to the servo "gas station" to fill it back up, apparently dyno time is thirsty work.
So full tank, warm fluids and back onto the freeway and a little pull to see what we have. Went to just over 7k and it needed to clear its throat a bit. I was probably a bit tentative. Quick u-turn to come back towards home to stay close and got to a just legal speed in 4th, 100kph or a measly 62mph.
Throttle reponse from idle had been lethargic, a quick blip back to 3rd from 4th and the extra revs definitely made it way more responsive. Mashed the throttle and hung on. It was definitely as described, from 6k its noticeable, it has a 2nd coming at 7k and absolutely rips through to 8500 with no sign of let up. Caught me by surprise the first time and hit the hard cut.
Just did a quick AI question. Glad i wasn't watching the speedo. At 8,500 RPM in 3rd gear, a 2017 manual S550 Mustang GT fitted with 305/30R19 tyres and a 3.55 differential ratio will reach a theoretical speed of 110.4 mph (177.8 km/h). Our speed limit is 100km/h and loss of licence is now 25km/h over that or above 130km/h as we do have some 110 zones. That is into the , we take your car and crush it zone.
Not that anyone would notice the effectively straight piped mustang at 8500 on a crisp clear night, sound doesn't travel far. :eek:
@Fabman , @Mad Hatter & @steveespo thank you for your input in this manifold combination. You guys are collectively dangerous. Track days are going to be a very new driving experience for me.

Now the mirrors are done, i was looking for something simple to tie it all in. Came across the GTD Spirit of America edition. Another quick AI and i think this could be simple but very nice. Just need to get the stripes the right proportion, AI went a touch fat in my opinion.
Open to other options if anyone has any ideas.

In Australia? With all of those wide open spaces? I would have thought they would be at least 140km/hr, maybe more.

I feel like Mad Max (1979) and The Road Warrior (1981, although you guys called it Mad Max 2) lied to me.

I always assumed there was an avid car culture there and that you would not have speed limits like Jimmy Carter era America.


PS - I like the graphics

More inspiration - Spirit of America “reimagined”

Oh there is an avid car culture, there is also some of the harshest laws in the world probably.
When enough idiots get into power, logic goes out the window.
It started with anti hoon laws, cars getting confiscated then progressing to having them crushed.
Speed limits in the city/suburbs have dropped from 60 (37) to 50 (31) to most shopping precincts being 40(25). Drive a 3 lane each way main road and it will jump from 80 to 60 to 70 to 40 back to 70.
Then there are speed cameras everywhere, fixed ones at certain traffic lights and mobile ones parked on the side of the road. We also have red light cameras, which i think are a good thing, that catch people running the lights and get them for speed as well. Our lights don't go to flashing amber late at night, you could be sitting at traffic lights with nothing around in the middle of the night.
Police pull over any modified looking cars and they get fined for just about anything that isn't stock. Even the 4wd guys get caught on bush tracks by police on trail bikes for modified vehicles.
Our fantastic state government has just announced that they are spending millions of dollars to bring in sound cameras to catch cars with loud exhausts. Its known as the Police State.
Anyone with a brain knows this is all in the aid of revenue raising as none of the money has gone back into road maintenance. Victoria ( the state where i'm at) currently claims the pot hole record for Australia. Billions in revenue and only a small % has gone back into maintenance. The sh*t is about to hit the fan here as a motorcyclist died yesterday after hitting one of our monster potholes on the highway. People are pissed and there is an election coming.
