2012 SHO Mod Recommendations

Where abouts in the firewall did u go through ? I did the same , although I heard there is the factory wire harness under the wiper cowl. Might redo mine. My hole is sealed and all, just think I like the other option better. Didn’t know do it at the time I did mine

I put mine in the hood release grommet. It's just under the gas pedal to the right. I just had to pull the carpet back and poke through it.

I tried to get in the factory harness but it was tight. I also thought about going beside the sunroof drain on the passenger side but didn't want to drill through the firewall.

What's your stereo setup?

Looks good.

SON OF A BI~%H ! I don’t remember a grommet down there I actually went through the firewall. Gonna go and look for it, gonna be a spring project though. Gonna be put away for the winter soon not about to rerun the power wire again now. But thanks for replying so I know now. Cool.

My wallet is a little lighter now. I just sent it all over the interweb...

- Unleashed SHO Power Pack
* (pack upgrade) Livewire TS+ Tuner w/ 2 tunes
* 6X NGK-6510 Spark Plugs
* Rat Stat 170 Thermostat
* 3 Bar MAP Sensor
- Airaid (oiled) CAI
- JLT Oil Separator (satin)
- Power Stop K5584 drilled/slotted rotors and ceramic pads all around

...and now we wait.

And I went ahead and swapped the 8" Kicker for the PT250 10" (picked up at Walmart). I'm not really happy with it either. I can't decide if the factory stereo is really good or the all in one subs just really suck. I wish I'd have went with Rockford Fosgate. They're 300 watt RMS compared to 100 RMS with the Kickers.

Why is the t-stat a good mod?

 

[Joshw0000]

It reduces operating temperatures. I've checked my car a few times while driving and the temp stays around the 190's. It's a recommended mod for the 3 bar MAP which allows for more boost. When combined with a tune, those 3 mods should give me the most power gains for the price.

Why would it reduce operating temp??? The T-stat only determines when the coolant will begin flowing. It has nothing to do with the efficiency of the cooling system.

I don't think the lower t-stat is a good idea.

The engine is engineered to operate at a certain temp and all the lower t-stat is going to do is slow down the process of reaching optimal operating temp, effectively making the engine run under the optimal temp for longer than intended.

How is that a good thing?

This is why I still have a stock T-Stat in my coolant system.

At first I would disagree with you. But after a little research, now I don't necessarily agree or disagree. I bought mine since it came with my kit and its recommended but now I'm not sure I want to use it.

If you look at the Livernoise 3 Bar MAP (not the one I ordered but same concept.... increases boost), they're starting that the colder thermostat is required - https://www.livernoismotorsports.com/product/LPP630000.

I'm hoping someone more mechanically inclined can chime in with some supporting (or not) facts about the thermostat.

Are you running a 3 bar MAP? Tuned?

Yes. 3 bar E30 tune here in Phoenix.

Temperature radiation is not linear so there is the possibility that initiating the cooling system before 190 degrees that the maximum temp in normal driving conditions could be slightly lower for a period of time. The tuner can also adjust when the fan will kick on.

I have contacted Livernois and spoken with a tech. I was not given much helpful information on how opening the t-stat earlier would affect the efficiency of the cooling system so... He did say that the vehicles with the lower temp t-stat had lower engine temps when road tuning but was not able to get any type of evidence for that clam.

In my personal opinion,

Not worth it and quite possibly detrimental

Have you spoke to Torrie at Unleashed? He's pretty responsive. Maybe he can give us some info about it.

I tend to agree. Everything that I have read about the new motors are they like to run at the temp the manufacturer designed them to run at. If people are getting more HP out of a T-Stat change, how much more? I don't think it is worth it (I think is a marketing ploy to have you spent $60 on a $10 T-Stat), and my car is doing fine here in Phoenix with my AJPTurbo E30 tune with the stock T-Stat.

Modern engines have to also be concerned with strict emissions and the operating temperature can affect the emissions the engine produces. I believe their may be a little benefit power wise but combined with changing the fan settings in the tune can help keep the engine cooler under hard use.

It's complete anecdotal but I can see a slight difference on the factory gauge with a cooler stat/tune.

 

[Joshw0000]

So as someone currently running the cooler thermostat, do you recommend it? I've already ordered mine but now I don't know if I want to install it? How long have you had yours in and how do you drive with it?

I have roughly 30k miles on it with an LMS tune and this car is my daily driver including a 50 mile round trip commute in heavy traffic. I couldn't tell you if the stat by itself made a difference as I did not run a tune prior to swapping it. I haven't noticed any negatives and no issues with it swapped back to the stock tune for a week or two and no issues in the cold weather.

 

[Joshw0000]

Ok good. I've already bought the part so I might as well install it. I assume the tune will account for it. I'm fine with no it minimal improvement, as long as I'm not causing issues to the car.
