Dyno power gains w/ stock SHO and LMS Stage 4

Lastly, if I take the Nestea plunge on this, I haven't looked under hood of car but pix make installation of thermostat and plugs very daunting! Comments?

Easy peasy stuff....

There are a couple of "How-To" tutorials I believe floating around....

If not, it's a fairly straight forward task. Not all that complicated really.

In lab testing way back in 2009, FMC tested the Eco power plant (3.5L) to 720bhp before they began experiencing "failures".

This was a direct conversation I had with various Execs back in 2010.

Now I didn't ask, nor was it volunteered, what exactly those failures were.... but suffice to say.....

720bhp is your upper end/range.

That's for the motor. What about the trans.

There are a lot of SHO's and ecoboost motors out on the streets.  Hard to believe there isn't some solid data on what these can handle in a DD role.

I'd be interested if 480-550awhp was reasonable for DD.
 
The 6F55 Trans is pretty stout.

But i'll be personally testing those waters (480-550awhp ranges) myself after I achieve my newest dyno tune from LMS to capitalize upon my newly installed ATP Turbo upgrades.

Still waiting on my hard pipes to arrive.... probably gonna schedule the tune though for sometime in January after the Holidays are over.

There's plenty of us though that are running around in the 400-440awhp range(s) currently, that haven't had any issues if that's any indicator. :dunno:

bpd... Cool. Anxious to see your dyno and impressions.

Did your engine cover still fit with the new turbos?

Happy Thanksgiving.
 
I am confused as to why my engine cover wouldn't fit?

If you are referring to the large plastic under belly pan then yes that still fits.

The decorative cover on top of the engine still fits as well (since each turbo is mounted down low, towards the bottom of either side of the engine block).

The turbo housings themselves did not change or increase in size.

I think that's why you're asking that question correct? Because you are presuming the turbos are bigger?

What was enlarged (on each turbo) were the diameters of the compressor and exhaust wheels. However the overall housings themselves remained unchanged.

Yes.. your correct. I was asking about the top shroud that hides the engine.  Considering painting  or hydroing it and also considering turbo upgrade... didn't want to waste my time.

:thankyou:
 
I don't have DPs but, I would bet you are looking at about 365 WHP.

BTW-This is what I am planning on.
 
4DR has a list he posted... sorry, I don't know the thread of hand... he lists them at about 20HP catted or uncatted.
 
No HP difference.. Just depends on if you want your car to meow or BARK!!!  I have catted downpipes but removed 3rd cat and mid-muffler. Also have "X" pipe and Magnaflows.  My car just GROWL's! LOL

Are you saying no HP difference with down pipes?
 
what's the difference in stage 3, stage 4 and stage +4 ?

I think I have stage 3. I hate leaving power on the table (especially free power) and I maybe leaving a lot out ?!?!/ is it the timing and fuel available ?

I think I only have 92 available around here.....

Will the XV1 be the top dog and trump stage 1, 2, 3, 4, +4 ??
 
Xv1 Will be the top dog.  I'm not sure if the have a 4+ for 91 Octane.  They didn't a few months ago when I bugged them about it.  I thought when I moved, I might only have 91 here.  Luckily, I found a couple of Speedways that have it. So, I didn't press it.  At that time Anthony told me that Stage 4 was the highest they went with 91 Octane.  I'm pretty sure that the Xv1 will come in 91 and 93.
 
I remember now.... pulled an old e-mail from Anthony at LMS. Stage 3 for 2013 is the same as previous years stage 4.......

For the AIW we offer either 91 or 93 octane performance which is basically stage 4 of the prior model years that used the SCT tuner.  Most customers chose to run stage 4 always so we didn't see a need to have multiple stages with the new device.  Here are the stages for the 10-12 SHO SCT tuner.

- Stage 1 - SCT X-Cal 3 w/ transmission modifications with reduced torque management and removed speed limiter
- Stage 2 - SCT X-Cal 3 w/ raised boost, increased timing, transmission modifications with reduced torque management, and removed speed limiter
- Stage 3 - SCT X-Cal 3 w/ raised boost, increased timing, transmission modifications with no torque management, and removed speed limiter
- Stage 4 - SCT X-Cal 3 w/ raised boost, increased timing, transmission modifications with no torque management, and removed speed limiter
 
Right.  So the Xv1 will bring 13's and 14's the extended boost of the 4+.  AND, will benefit ALL SHOs with higher boosts along with cooler temps using the 170 Thermostat and 3 Bar upgrades.

NOOOOO... just no difference between meow and bark....  Downpipes, whether catted or uncatted are almost equal... cats are high flow and don't restrict much, especially when you add more pipe behind.
 
I asked the folks at Airaid what the dyno gains in WHP showed with the current version for the stock SHO... below is the email reply;

Hi Tom

Increases of 9hp and 15ft/lbs were seen with the Airaid CAI on the Taurus SHO. These increases were seen at the wheel with no other performance modifications. Let me know if you have any additional questions or concerns.

Don't know what applies with a tune... anyone with some dyno information?
