Dark Horse cam install?

[robvas]

It's not much more than the stock engine made with a cobrajet intake, headers, e85, and tune

that makes sense, but those number still seem unsafe

Why is it unsafe? These motors are reasonably reliable it seems making a bunch more power with forced induction on a high compression motor.

You won't have big torque down low like you do with a positive displacement blower which loves to pretzel rods, and you won't have insane cylinder pressure like you do with boost making almost 200 whp more.

So long as the AFRs stay sane and you aren't going wild with EGTs I don't see why this wouldn't be more reliable than a blower, which is already reasonably safe.

Also Coyote's are reasonably cheap to replace if the motor does die, so that does work in your favour.

Cams were only worth it on an S550 if you had a Cobra Jet manifold and full bolt ons and supporting mods. I had a GT30 manifold and did cams twice (Comp stage 3 cam, then down to stage 1) and revved the engine to 8,000 rpm, and it really wasn’t worth the hassle or cost. The stage 3 cams lost power all the way until 6K rpm, and then only picked up a peak of 11 hp. The stage 1 cams were better for the GT350 manifold as the power was closer to stock in most of the rev range (ie, the car didn’t lose power) and they picked up more on the top end (but still not enough to justify doing them, IMO).

if you want to stay NA, that’s fine, but obviously from a cost to power standpoint a blower is just a much better deal. Regardless, you can’t tune the S650 for cams right now so it doesn’t matter. And OP, cams on these cars don’t sound any different than stock.

looking back on what i said, that was nonsense. i think i forgot how bulletproof the Coyote engine is. also, i'm pretty sure i was confusing something. basically, just ignore my previous comments as they're pointless noise. im gonna justify it as "bored with nothing happening at work at 13:00 on Friday, so i'm not really paying attention"

Probably wouldn't be much different than a gen 3 setup with cams

Prescient.

Some of us would have died to get 500 hp out of anything back in the day. The Coyote is still just an ~5.0 liter engine. Yes, they're bullet proof, but for how long with what mods?

Your DH has better cams than the GT. There is very limited stuff out there until they unlock the computers. Then you will be able take advantage of the new cam. You want to have fun put a Whipple on it that's what I did to my DH and I love it.

How bad/loud is the whine? I really enjoy the sound of my exhaust and when i watch those dodge videos where the charger/challenger has a super charger, I just can't stand the whine.

You cant hear the new whipple, especially inside the car. It’s silent compared to dodge blowers.

Saw some kid in a very dirty Mustang recently driving through a large strip mall with a ridiculously loud SC whine (probably coming through his radio, LOL). Don't know what it was but he apparently wanted everyone he could find to hear it. I couldn't stand to drive a car like that.

Straight cut gear centrifugal?

I love a bit of blower whine. The GTD is about perfect for my taste. I can't stand the sound of those big Roots blowers many Hot Rods seem to have.
And, I wouldn't bother tuning an good N/A engine these days. The factories seem very good at getting reasonable power with reliability

Ford has come a long way. Decades ago, it took nitromethane fuel, a supercharger, and Phase 4 heads just to get a ford V-8 to 600 whp.

• Goose: You can shut the gate on this one, Maxie... it's the duck's guts!
• Barry, MFP Garage Mechanic: [excitedly] She sucks nitro... with Phase 4 heads! 600 horsepower through the wheels! She's meanness set to music and the bitch is born to run!
• Goose: He's in a coma, man!

I don't hear any whine. The Whipple on the Coyote is very quiet. Not like the Hell kittys.
