Which LT Headers to get?

[CY_S550]

I am very happy with the ARH headers. Got me the power/torq and sound I was looking for.

I am. And for the record, the sound is glorious. I couldn't get the car over ~420rwhp no matter what we did. Different gas, cats, no cats, it didn't matter. Over 80 miles on the dyno over about a week. I'm not saying that SW is a bad system. I'm saying that if you're going for maximum power, ARH or Kooks is probably the way to go unless you're doing FI, which I am. My car did 390rwhp stock on three runs.

The same tune and intake on the shop car but with ARH LTs and a custom X-pipe into the factory mufflers made 450rwhp. That car made ~375rwhp stock.

Correlation does not equal causation. But that's the facts. Beefcake will be here to destroy my results shortly.

This compassion you speak of was pretty controlled since the shops dyno is in doors, so temp and other elements would be pretty similar I would think.

At the dyno now.

Quick graph, will post more numbers when finalized.

Full ARH setup without Cats.

Thank you!

so 549 crank hp with headers / intake / tune

ford sure left a lot on the table with these cars....

that's probably conservative with irs too, might be more like 20% loss than 15%

Everyone's eyes perked up with those numbers. A bit surprised.

Seems high for n/a from everything I've ever seen on a coyote.

Bring that car to cincy lol.

Can't wait to see the track mph

lol, you gotta remember we're doing road course. We're doing before and after lap times. Not so much 1/4 mile times.

1/4 mile really tells the tale on power though

No doubt, road course is just our thing. I'll test the car out when the weather clears.

that std or sae?

STD....

i would think there are many points to be argued when it comes to this as we have no real testing across all brands keeping the constants the same. Car, fuel, Dyno, weather. I would love to see someone do that, I think we would get a lot of great data.

We have limited data. The data we do have suggests that Kooks and ARH will give you more power for your money. Most of us can't afford, or don't want a 1000 HP DD, so if we are going to spend ~$4000 wouldn't we want the most HP we can get?

 

[jayman33]

Correct, STD. Still fine tuning.
