Love the grille but my car is far from a cobra, plus I'm still trying for a sleeper look. It will make more sense once you see it installed on the car.

The newly printed part is the backing for the horse and it's the filler for the cobra outline in the grille.

You should seriously think about making those things for sale.

I would sell them if anyone wanted one, we figured out what went wrong with the printer so the next one would have a smoother finish.

I got the alignment done today at interstate ford. They were all really stoked on the car. Lexiion was right they did not need to hook it up to the scan tool.

I took it for another drive down the road to check the steering and it still feels weird to me. It definitely does not feel like my Shelby, it's almost as if the epas is turning off when I drive faster. The steering is really sensitive and stiff at 50 mph but feels normal when I'm going slow. It feels like the alignment is still out, it drives straight but its so sensitive that I was constantly adjusting the wheel back and forth to keep it straight.

Maybe I'm just trippin, Lexiion needs to drive it to see.

I guess not having the speed sensor working correctly will contribute to that. EPAS needs the speed sensor.

I think I might know what's wrong, the car was aligned to 2010 mustang specs with hydrualic steering. My car should have been aligned to 2011 specs with an epas, the specs are slightly different. I told them it had 2011 steering but they didn't think about pulling up 2011 specs.

Ahhhh yes this could be contributing too, probably more than the change in specs between 2010 and 2011 mustang.

I am pretty sure they aligned mine to 2010 specs, too

Shelbys have different specs than the GT/v6, if they aligned you to 2010 GT then it could still be out.

This is 2011 specs

Can't find the sheet right now. I will look it up.

For sure the speed sensor not providing the correct value will make the EPAS steering efforts be wrong.

I believe you guys are right, makes sense. I've read that the epas changes steering feel at different speeds, without knowing the speed it can't make any adjustments. I'm just glad to know its not going to stay the way it is now.

On my todo list for the ecoboost battle was a larger throttle body. I've been speaking with vmax motorsports about porting and texturing my stock TB but wasn't really sure that would be enough airflow to get the gains I was looking for. I'm sure that it wouldn't make much difference on a stock or slightly modified motor but when everything else is being pushed to the limit I'll probably be held back 5-15hp with the stock 68mm TB. BBK makes a 73mm for $450 but I don't think 5-15hp is worth $450 at this point.

I had an idea....how about using an 80mm 5.0 TB on an ecoboost? Well I looked it up and there have been a few people that have done it for the 3.7 and claimed positive results.
http://www.mustangevolution.com/forum/f356/t356045/

You drill new mounting holes in the TB housing and bolt it up, plug it in. I'm going to take it a step further and have vmax motorsports port my intake manifold to match the new TB. I'll have them also texture the inside of the TB for better airflow. The texture is pretty interesting, check out their website for more info. Really nice guy! http://vmaxmotorsports.com

I went on eBay and found a new 2011-2014 5.0 TB for only $60 with shipping
As soon as it arrives I'll pack up the intake and TB and send them to vmax.

I saw someone poo-poo this build, stating that it "wasn't cost effective". Car guy sh|t has NEVER been about "cost-effective".

I agree...

Buying a gt500 for $70k and it depreciating $20k over 2 years isn't cost effective either, but many people were ok with that lol.

If a person says the project isn't cost effective they don't understand that I'm building a race car which has a high cost. Had I bought a 2011+ v6 mustang and changed to an ecoboost it would cost much less. $3,500 for an engine and $2k for the control pack. Custom turbo piping, air-to-air intercooler, and a small amount of exhaust fabrication would cost around $1500 which is what you can sell the 3.7 motor for. Seems pretty cost effective to me, it's at least as cost effective as a coyote swap but you get twin turbos and a forged bottom end. Its not nearly as plug-in-play as the coyote swap, but that's what's going to make these swaps more rare.

Of course if you were swapping this in to anything besides a 2011+ v6 mustang you would need a transmission too but 3.7 standard trans are around $1000.
