500RWHP NA

Pinero61, Any port work or oversized valves on your setup? Stock rods/pistons?

Heads are stock, along with the rotating assembly.

I plan on doing a full build within the year with a direct port nitrous setup.

Yes making power doesn't mean you can drive it worth a crap on the street. Most of the 5.0 crazy NA builds have the cams locked and make horrible low end power which makes it very hard to drive on the street.

Mine drives fine, even with too high of gearing.

Even with big cams, these engines are more or less tame until you lay into them. No big lope, like the LS cars. You'll lose torque, but gears are an easy way to correct for this. You'll need them anyway, if you're increasing RPM. I gained 35 mph in forth gear, so dialing that back to near stock mph/gear will make it feel like I got my torque back.

3.73s are very short already. I've got 3.31s in mine.

True enough, but the extra rpm and lack of torque made the need for something even steeper apparent. If I had the power to do it, I'd reach 201 in 5th.

An effective 4.30 ratio will get me back to the same mph per gear as I was stock w/3.73's. So, I get my low end back without to having to run in a higher gear than i did stock at the same speed.

Wow 4.30s sound insane with the already aggressive transmission ratios that we have unless you have swapped to a T-56.

 

[pinero61]

Nah, MT-82 here. That's how much the extra rpm affected the car.

Maybe one of the reasons we haven't seen many cam jobs is that these cars are too new still. People are still quite a few miles from warranty end. Superchargers and other bolt ons are removable. Cams, not so much.

I'm only at 7800 miles, so tearing into the internals isn't high on my list at the moment. For all I know, my warranty may be kaput with the tune, but there's a chance it would still offer some protection. Once I roll in with cams I'll be dead in the water for sure.

It's on my list, but I'm still quite a few miles from making the change. I wouldn't be surprised to see some '15 cars starting to put them in this year so we can see some real numbers on what can be done with them.

What's did it cost you time wise, if anything?

I get that there's some loss of low end, but I can cook the tires off the car now through 3 gears if I really wanted to. A little less might not be so bad in 1st or 2nd. I can't imagine it's bogging with cams, especially when shifts should be dropping you right into the power band.

I'm sure I'd see what you mean if I were driving. Just trying to understand the difference.

Driving-wise, it's fine. The car still makes 350 ft lbs at the wheels, so around town and cruising the car pretty much feels like a stock car. Once you get on it, it feels okay until around 4,500. Then, it starts to pick up steam, and just punches you in the face past 5,500.

Between shifts, it never drops below 6,500, so you're always in power. The gearing is mainly effecting getting the car out of the hole. On 28's it's bogging out the hole. I'm trapping at 119 on redline in third.

This isnt an OHV engine cams dont take much more to put in than when people go have the OPG and Cam Sprocket upgrades done.

I think the main reason not many people have done cams is quite honestly the variable intake and exhaust valve timing is pretty impressive on the coyote.

Being able to advance and retard the intake cams seperately makes it a whole lot easier to make a "1 size fits all" or even stock cams pretty good for NA setups, Supercharged Setups and Turbo Setups.

Depending on the power adder for example with a turbo setup its pretty easy to advance the exhaust timing to get the exhaust out faster too.

Being able to adjust the intake and exhaust sides independently tuners can pretty much change the valve overlap too before VCT that required a completly different cam grind.

No way these cars are too new. They came out at the end of 2014. thats over two years old for some of them. Im close to 50k miles already and I know others are the same. I also know many people buy them not because of the warranty but to turn them into their race cars.
I think four independently variable cams intimidate people or most shops prices to install them are extremely high. Why haven't more of the vendors installed them to show them off and sell more of them? IDK bad profit margins maybe. :shrug:

I think it's mostly due to costs for cams installed being up to $3000 total. Bang of the buck isn't that great for most.

 

[16MustangVet]

Labor should not be 1500+ on cams......

Exactly. Why a vendor doesnt have a all out NA build to brag about I don't get. Staying NA and getting the most HP is a popular route.

 

[16MustangVet]

Huh popular route? Cmon people i love na builds but a max effort NA build is looking at 1200+ in cams 4k+ in heads 1kish or more for intake 1500 for headers/exhaust.

thats almost 8k in parts. not even including fuel system or cranking up the compression with a set of pistons too.

the popular route is go FI make 700whp and call it a day.

sure bolt ons are popular but max effort big HP NA builds are anything but. They get expensive very fast HP to dollar wise.
