hello all,
Thinking of coming back to the GT350 platform. Spring of 21’ traded my 16’ GT350 for a 18’ C7 Z06(7 speed stick). Wasn’t really a huge fan, maybe that will come with age. Few months later traded in for a 21’ TRX. Had TRX for almost a year, but I already have diesel truck that’s about 10 years old I use for truck stuff, so I figured it’s about time to get rid of the TRX. I miss driving a manual, so I have found a few 350R’s I’m interested in. Found 2 350R’s that are identical only difference is one has a whipple on it and the other is stock. I wanted to go forced induction on my previous 350 but just seemed like a ticking time bomb. Anyone have first hand experience with supercharged 350’s? Also, for R owners about how the cup 2’s wear in comparison to super sports on base 350. Is the added price worth getting an R?

My cup 2’s were awful for the roads, maybe they’re great for the track but not on the roads. I put on super sports and drives beautiful on our highway trips.
The thing that sets me back about adding forced induction on a 12.1 compression engine is what you said “a ticking bomb”.
There’s a reason Ford made the GT500‘s predator engine at 9.5 compression ratio. Long term durability. Even though the 19’ & 20’ GT350 has improved rings for better sealing, mine will stay stock the way she was made and just enjoy the ride. Good luck on your hunt!

Since 2019 all GT350's have the R motor and upgrades so other than the badges of being an R, which are neat, the difference is there is no back seat in the R. As far as a supercharger or not it has to be your call due to how much money you are willing to take a chance on spending. I think if you are willing to spend the money for a new motor then the supercharger is the way to go. I have a friend that has a 2020 and had one put on his but he has the money to purchase a new motor and not even think about it. I have a 2019 and purchased the extra warranty when I purchased the car because the motors are expensive and I don't have the supercharger. As far as the cup tires they do not last long even if you don't drive the car hard and the super sport tires last and the car drives much better. When driving on the back roads, with the cup tires, the car wanted to move around as the road would make the car drive bad. I held on to the wheel with both hands. I did (2) things; 1. purchased a set of super sport tires and another set of stock wheels in case I wanted to put the cup tires back on; 2. I had the car aligned to take most of the negative camber out. My car drives like a different car and I love it. I still don't have but 3,800 miles on my car but when I drive it I really enjoy it so much more than I did because my car doesn't run all over the road and I can drive with one hand and be comfortable doing so.

I can weigh in on both - the CUP2’s feel greasy and sticky all the time and wear fast - not even good in the track - go Hoosiers if you want to feel the car run on the track like a champ.

At the GT350 Track Attack, they run 4S and the cars are solid and consistent.

I have an 18R with a ported Whipple, Kooks long tubes, 10 rib pulley set up. Whipple set up was installed under 1000 miles and ran 908hp to the wheels with 14psi on 93 octane - not a problem in 26k, since then swapped to a RPG Ford Performance stage 3 sleeved race long block pushing 1200 to the wheels with 21psi.

a whole different animal with the blower.

Have a 2016R with 3.0 whipple on E85 tune....runs great...at the track it just goes and goes....no over heating issues and then again it only 20-30min sessions and about 75-95ish degrees give or take...
Car is awful on the cup 2 but better alignment and problem solved. Running the supercar f1 tires and seeing how long they would last. Car runs solid, but it could be a ticking bomb...I'm okay with it, cars are meant to be driven and when driven hard something will need fixing or replacing sooner rather than later...cheers

I'll address the second part of your post by saying that I went from sport cup 2's which - ran like crap on the street - sport cup 4's - which are a dream.

And I required a four-wheel alignment and I run nitrogen at 34 lb of pressure - and it works out perfect


As far as forced air induction goes. I bought a 2016 GT350 4 previous owners 39,000 miles.
And I blew my motor 1500 miles later.

So the takeaway is - even with a 2 owner car - let's say 20,000 miles - I believe in stock trim - it would in fact be a ticking time bomb...

So I am building a new motor basically from the ground up. And we're not talking about a rebuild. And we're using high-end aftermarket parts. And so my internals will be much stronger than the stock Shelby GT350 engine ever was...

Now is the perfect time for a Supercharger.

So in my case since my Shelby is a "high winder" anyway - I don't mind a little lag in the beginning of the curve. And at 4,000 RPM and up to 8,250 RPM - my Pro charger will be a screamer

2016 GT 350.

Putting a Procharger P1 SC on a new build 5.2L Voodoo. Only parts on original blown motor used are crankshaft, both heads, original 4 cams. Everything else new from the bottom up.

So the takeaway is you got to have Deep Pockets when they use forced air induction - if you're putting it on a moderately used engine. And with any kind of boost you could conceivably cook that well done! So better off to drop 25k and start with a new upgraded motor for the increased reliability and peace of mind....
