Many of you may know FathouseFabrications offers several levels of twin turbo upgrades for GT350s that build lots of HP.
Here is a link to a video describing 2019 GT350 engine changes they know about. The car in the video is a 2019 GT350 getting ready to receive a twin turbo upgrade. Notice they say the new GT350 engine can handle 12lbs of boost and have many upgrades. Exhaust valves, Rods and more.
For those who are going to go nuts over this, its just information that will take time to confirm.

The real question is do any of these "upgrades" benefit a NA voodoo engine? Or are they just added unnecessary strength & weight for the sake of commonality between the voodoo and predator motors to save $ in production costs.

Seems sketchy they credit this site for the info... i was thinking maybe they tore one down and confirmed changes, but doesn't appear so.....

Cost savings is almost certainly the answer. I'll take a lighter Voodoo any day.

hard to tell still. im sure some of the changes were for sharing parts with gt500. but wouldnt they need different rods since different cranks? as long as they improved reliability and strength.. from what i have seen there seems to be at least less consumption issues if not 0. i have only seen 1 or 2 19+ failures. 6 months from now hopefully we know more.

This. I was excited about seeing some kind of tear down. Reminds me of when I was waiting on ordering my JL generation Wrangler, and there was a huge forum thread talking about changes in the new generation. Then a Youtube video came out from a supposedly reputable source that everyone in the thread thought was confirmation of the changes discussed. Turns out the video was citing the very thread itself as the source of information. Talk about the tail wagging the dog...

It looks like the radiator support frame has the GT500 hood pin mounting points cast into it.

Figured I would throw this out there as well...this is the dyno sheet from this specific 350’s baseline on their dyno before they boosted it.

For comparison, here is a 15-18 350’s baseline on that same dyno...

can confirm, mine has that as well.... i've been wondering if it's an easy hood swap and how much the hardware for the pins will be...

I'll have a detailed write-up on that as well as fitting the cobra jet intake under the new strut tower brace after lowering the engine once the parts are available.

Lol yeah, all they did was talk about the info posted in the Gen 2 Voodoo Thread. Nothing new in the video just rehashed for YouTube.

2017 GT350 now gone to a great home.
Thanks for those dyno graphs :thumbsup:
Yes, thanks. So, is this Particular ‘19 down on power? I thought the ‘19 cars were making more horsepower than ‘17-‘18 models.

It's not conclusive of anything in either direction. It's not necessarily down on power. Nor was there anything to show the 19's make more power other than a previous dyno run where one put down a higher number. These are just examples of how variable dyno runs are and how many factors affect the numbers. There are almost too many to list. There will be variations in both dyno runs and between engines themselves. A dyno isn't a great tool for comparing power output between two different cars. Doing runs with both cars on the same dyno on the same day will help, but there will still always be variations. Even if you run the exact same car on the dyno three times in a row you'll get three different numbers. A dyno is useful for tuning and assessing power and performance during tunes and engine builds or modifications, but not a strict meter stick for making comparisons between cars.
