GT350 Engine Mods?

[Fabman]

I'm not disagreeing with you. I have a F150 I use it in when I take it to the track.

I have a Eco Boost Tremor now, but my last truck was a flex fuel F 150 too.
It was nice that I could use the same fuel in both.
If I got a load of fuel that I didn't think was quite up to par I just burned it up in the truck.

In all honesty I wouldn't change the stock headers to aftermarket shorty headers. If I lived in a strict EPA state I would add borla catcback, tune, reduce rotating mass, and put the car on a diet. Don't get me wrong I love my ARH long tubes and catless x pipe, but changing the oem headers to aftermarket shortys is not worth it.
With ARH long tubes,
Catless x pipe,
Lund tune for 100 octane race fuel I pulled 536 rwhp. Using stock cai.
I've also dropped nearly 180 pounds from my car and will drop a few more from it soon.

Good luck on the throttle body!
That's a unicorn. I've been chewing FP ear on that for months. Not gonna happen.

I agreed about the headers. I would either do long tubes or leave the factory shorty headers. I would ask Shaun / AED if they have had success with long tubes and cats not throwing codes and the emissions monitors completing. Other than that, a cat back, driveshaft, and lighter wheels to loose weight.

Lol. Yeah that adds up quickly. Not sure why my last post listed twice. Sorry

I have a bone stock 2016 short bed regular cab f-150 2.7 ecoboost with 500 miles on it, last summer I ripped off a 13.71@100 mph at my local 1/4. It also rips off 0-60 in 5.2 seconds. It's 100% stock. I couldn't believe it. My 2013 f150 5.0 is slower lol.

I had a 2011 short bed reg cab 5.0 and my 3.5 EB way out tows it. Never ran either at the track but I'm sure it's faster too. Took a while to get used to the turbo v6 after being a v8 guy for so long but so far I can't complain about the performance.

I did not see any shorty headers for Voodoo motors...

JBA make shorty headers for the GT350.

I agree completely. I love my 2013 fx2 5.0 it's a runner and comfortable. But my 2016 is lighter, and faster with nearly 1/2 the displacement.
It's amazing how weight reduction improves everything. I noticed a huge advantage on my GT350 when I reduced the weight. Especially the wheels. Only downside with weight reduction is it's not always free lol.

I'd be surprised if they made any more power than stock.....

I do not see any advantage with aftermarket shorty headers. Don't forget the 5.2 firing order is it's beauty.

I was just answering the question.

The stock header is a little funky, but yes, probably not much gain there.

Yes they show them but I can't find any info on installs or a set for sale. Maybe they aren't available yet.

I have friends that know Jay Bittle (...and I raced against his '68 302 Tunnel Port A/S Mustang a few times) if could ask them to enquire from him if you wish.

 

[VoodooBoss]

Thanks for the offer but I'm in no hurry. The Kooks shorties on the 5.0 are good for about 10 HP and if I could get that much on the voodoo I'd consider it with a tune.

I know for those in CA or other similar states it may not be an option but it is an easy swap with the Lethal Perf off-road mid pipes v2. It is quite loud (still have the resonators)in sport/track mode so tracks with decibel restrictions may be an issue although I have seen a recent plug solution to force the exhaust through the muffler such as normal mode. I am also running a Lund tune on race gas (101 octane - $7.49 last I was at the pump). No dyno numbers but other similar setups/dynos tell me I am at 500ish at the wheels. Very noticeable gain especially mid range. Still waiting to hear more feedback on the CF driveshaft before I make that jump.

Tell us more about this? This would be a nice solution for those of us driving and sound restriction tracks like Laguna Seca.

It is posted in the 6G forum. Looks like a compression rubber plug.

Was the rumor of Ford producing some type of "trackkey" style tune for the GT350 just a rumor? There are a few features I wish they would ditch like the way it holds the RPM for a second after you lift off. The trackkey option for the Boss was awesome, I wish they would do that for the 350.

It wasn't a rumor but it's been killed and won't make it into production.

Well that sucks...I know you have the connections Rick but how did you discover it was cancelled?

@BigTaco found out at SEMA and posted about it.
