Who is doing Naturally Aspirated builds?

I really want to read more about non FI builds. Links to Member or Vendor build threads would be great

or if you would just like to share your NA build info here that'd be awesome as well. I'm sure not everyone will create their own thread for it.

Personally I might not, just depends on how much modding I do at one time once I get around to it.

If you want to share here; at least list your mods, dyno numbers and what you have your rev limiter set to. Also weight reduction modification info would be great as well.

happy posting :cheers:

So I haven't made any mods yet, still waiting for delivery but i don't plan on modding heavily for a while but i've given serious thought to an awesome N/A build and what products i would go with. Here it goes...

Motor mods:
1) JLT CAI
2) Lund tune
3) Kooks LT headers paired with FRPP Touring catback
Those mods i've seen from other forum members netting around 445whp.
4) ported heads and cams would be the next step in my mind

Weight reduction:
1) FRRP Touring catback ~30lbs
2) Aluminum drive shaft ~15lbs
3) lighter wheels (PP wheels are heavy) ~5lbs a wheel for a total of ~20lbs (some wheels could save between 5-10lbs
4) two piece front rotors ~10lbs per rotor for total of ~20lbs
Those mods will net ~85lb reduction. There are several other ways to cut weight but those are the main ones i'll eventually do.

I have Steeda CAI
Corsa Extreme Cat back
SW headers on the way

Intake manifold if they design a new one

If you're willing to delete the rear seat that's another 25lbs. A lightweight battery would be 10 more.

Thats a solid 120lb weight loss

i don't think they'll be doing cams for the s550.. maybe intake manifold like Tony has mentioned.. are u just talking horsepower or track time?

Why would they not have cams? They had cams for my little 02 Focus. Just because they improved the cams a little doesn't mean they won't make something more aggressive

I am doing one, trying for a 11.99 before I go twin turbo (or supercharger I can't decide).
I have ran 12.28 so far. With my revised tune, with better shift points, I should be really close. It was short shifting 1-2 and 2-3 after the converter install. I'm waiting for Magnaflow to start producing their 3" exhaust for convertibles before I go back to the track. Race weight is right at 4100lbs with driver (car weighs 3915lbs). Mods are in my sig.

the cams in these cars are the exact same as the comp cam stage 3's.

Do you know the duration of the stock cams? There is a lot more to a camshaft than just lift. I can all but guarantee the Comp stage 3 cams are much more aggressive than the stock 2015 cams.

Stock 2011-14 Coyote cams:

Intake: 12mm lift, 260 duration
Exhaust: 11mm lift, 263 duration

Stock 2015 Coyote cams:

Intake: 13mm lift, ? duration
Exhaust: 13mm lift, ? duration

Comp Cams Stage 3 Coyote cams(http://www.americanmuscle.com/compcams-xfi-nsr-stage3-1112gt.html)

Intake: 12.5mm lift, 276 duration
Exhaust: 11.5mm lift, 283 duration

Cobra Jet

Intake: 13mm lift, 263 duration
Exhaust: 13mm lift, 290 duration

If the next Cobra Jet has a NA option...it will need cams.

The Stage 3 cams may have the same lift, but those cams required crazy tuning or lockouts to handle the duration.

Unless we're talking about Koenigsegg's free valve concept, any engine will need cams.

I've got a 2015 for sale on my local Craigslist, had to sell for other reasons but he claims if put down 502rwhp with an intake, tune, cams, and a catback.

So apparently someone has done cams...but I haven't seen any on here yet...

At a dealer now. Still haven't heard who did the work or anything, though.
