Speaking of food - some good smells coming from the kitchen. I tell my wife it's good, and she will say she's happy for me (sarcastically) because she still can't really taste or smell ... her round with covid was early August.

I’m just now getting my sense of smell back and I had it the third week of August

So kinda weird question maybe, but here goes:

So if I bought a mustang new, 450hp, and I put aftermarket heads on it like you said above...how much HP would it generally gain?

Or would you have to get bigger injectors and high pressure pump...

Or get new headers and exhaust...

What I am asking i guess is does replacing the heads make you need to get more air and or fuel in order to make more power? Or is it just bolting on more power?

How does that affect something like a supercharger or a turbo?

Greatly envy you and 72 for your know how. I have always changed my own oil and brakes etc ...but other than replacing starters, thermostats etc....stuff outside the actual engine block...I dont know what I am doing. I have no more business opening up an engine than I do a nuclear weapon....

I haven’t kept up with the newer Mustangs and don’t know what the bolton potential is right now. Back in the early 2000’s they responded well to headers and new heads though yes.

As for the fuel system just find out what it came with and you will know what you need to do. But if you start at 450HP you already have a fuel pump and injectors sized for that and probably more.

Think of a fuel injected engine like an air pump. Air is horsepower because the computer knows the amount of air entering the engine and thus adds the right amount of fuel to that air to hit the proper ratio and the fuel has a specific amount of energy that is released when burned. What you are doing by adding or reworking heads, adding headers, etc is increasing volumetric efficiency. This is why a turbo or super charger works so well because it just stuffs more air in there.

But a Coyote 5L making 450HP already has to be making pretty damn good volumetric efficiency. Back in my days we would hope to get my 4.6L DOHC up to around 450HP with ported heads, headers, reworked cams, and intake work and it wasn’t easy. This crosses brands too. Any modern engine is just an air pump. There are calculators out there I’m sure to help with this too.

but I will tell you this. If you’ve got a real 450HP street car with street legal tires it’s going to be a handful anyway if you aren’t used to it. Learn to drive that car first and educate yourself while doing that.

Hope this answered some questions.

One more comment on boltons. Probably the most straight forward way to make horsepower with any engine is to add a power adder like a turbo or supercharger. And with today’s reputable kit mfgrs it’s fairly easy. It will take what you’ve got and just multiply the volumetric efficiency by X. It will also retain its mild manner when not in boost. But. It also greatly increases engine stress by doing it. So eventually you’re going to be going in there with forged rods and pistons, maybe a difference crank but not always, so while you’re in there you’re gonna do the usual power adder things too.

It’s a never ending death spiral.

I had a’91 5.0 LX..... I still miss that car. I’d like to find an older Cobra or Fox body convertible, but I’ve got 5 freaking vehicles and don’t have room. I guess I should build a detached garage

450 hp on street tires will demand your full attention, especially if you don't have have traction control.

I'm at breaking point now. My wife has 2 cars and I have 4. I have indoor parking for 5. Time to build another garage or sell a car. I would rather buy car another than sell one.

Yep. I’ve done it and know it. I know you do too.

it’s all fun and games until you grab third in a slight curve and one tire loses traction. 😳

I've watched the rear end of my car completely pass the front end (past the point of no return) 3 times that I can remember, and come real close a few more times..

Yep me too not that many but I’ve done it. It’s a sinking realization when you reach the conclusion the attitude of the car is beyond a point that you can recover. Luckily for me I spun off the road which had no curbing and just into an open field. Literally just drove it back out and kept going. Whew!

A few other times that didn’t reach that point and I recovered but still filled my drawers.

Speed doesn’t kill. Horsepower kills.

2 of my 3 complete spinouts were in the rain. The other was youthful stupidity. I only hit something once, and it was a fence post. So far, I still have never hit another car, just one minor wreck with a fence post. I have been watched over apparently.

That’s what’s funny about it..... only while I was sick did it affect my sense of taste.... and even then I could taste.... it was just muted..... had chili last night 😁

My wife seemed ultrasensitive to salt for a while - probably she could taste that and not other flavors. What I think is really concerning is that sensory changes are probably neurological, and that backs up some newer findings about covid and lingering effects in the brain. Not sure what that says about the thought of herd immunity.

I got the concrete divider on I-24 coming into Chattanooga in the rain once - those concrete dividers don't bend much at all. I was in a Toyota pickup, had been on back roads and up and down Monteagle in the rain, and wasn't doing anything excessive or weird when the back end started a slow slide. I started to correct and I have no clue what happened between that and looking at the barrier coming toward me, but I did decide at that point to get on the brakes because nothing else was doing anything close to normal. While I was waiting for the wrecker, I could feel how big trucks make the bridge bounce. I've got a feeling a lot of wrecks there are because that bounce unloads the tires and the traction just goes away. You see dips and rises in the road and correct accordingly, but you can't see the bridge bounce, and when it's curving at the same time ...

For the first time in forty years, we left the light off. We didn't even buy candy. Normally we get a couple of those big bags from Sam's and take out what we like - and still have lots of the other stuff left over.

Went over to a friends. They had about the same. There were even two groups, one young one old, that didnt even grab candy. Came by, chatted for a bit, said Happy Halloween, and kept moving. Pretty much every house doing candy had people sitting outside to chat to, and were open to inviting people to hang out for a while before moving on.

Besides candy we had a s'more station going next to fire pit. Only one person took part in that. Several did sit down and chat for a bit.

I’ve got three right now that are marked to come down and two that started thinning this summer. I doubt they’ll come out next year. One of them is a monster, but thankfully far enough from the house that I can take it down
