Differences in Motor between R and non-R

[Muligan]

Let's start some rumors.... There's a secret dyno room where they pull the pick-of-the-litter engines off the line and put a tiny red paint mark in a hidden spot to identify those engines as destined for an R-model....... and that's why they only build a limited number of those cars, there just aren't enough cream of the crop engines to go around.

Y'all don't know wtf you're talking about.

Differences in R motor are:

no resonators
fuel injected brake lines
larger capacity blinker fluid container
magnAride programming
world hunger
making america great again
hi flo air cleaner
non gmo
race car

I already removed my resonators so I should have the same power as an R, but I couldn't find these parts on the Ford Performance site...

fuel injected brake lines
larger capacity blinker fluid container

Do you think they'll offer them for sale later down the road?








p.s. I don't care about the World Hunger mod. It would probably cost as much as those ceramic lug nuts!

Not directly engine related, but always wondered why the restrictor plate in back of the grill was different on the Rs vs non-Rs. Its such a small difference, that it seems trivial, but must have been done for a reason (thinking aero?).

Total airflow into the engine compartment is a concern as is adequate cooling. I believe the larger, regular GT350 opening/small splitter balances with the smaller R opening/large splitter.

Most likely yes, but they'll be $12,600 and $8,400 list price, respectively, to keep wankers like me from putting them on non-R cars.

Exactly. Probably wouldn't notice it - but if you install the R splitter, the "correct" related mods should be the rear wing and the restricted front plate.... It's not a horrible install *had my nose off already* but not sure I'd do it just for that...unless the nose was off already.

Everyone knows the cams are different. The R also has the "red" key standard. That's why there will not be a race key option like on the Boss.

What's bad is 4 people liked that post from the R owner..

Actually, there is a secret engine line where the motor's labeled "R" are pulled aside into a spray room and sprayed with a liberal amount of Pixie Dust. Non-R's don't get this Pixie dust, and it shows.

You can even tell when in reverse.

I don't think this is CARB legal is it? Or is this just for cars sold outside of Cali? :shrug: :lol:

It's killing me waiting for my body guy to finish my decklid. I hope to have it on Monday so that I can finally add my C2C R wing for good. With an R splitter in place the next project may entail canards something along the lines of what Multimatic does, maybe with my own twist. But you're right, there is definitely a balance there and having everything in place is the right way to go about it.

There is a track key option in the computer modules. It can be accessed via FORscan But does nothing......:shrug:

The R models have a bored-out cigar light socket.

I called my insider at Ford Performance ... he promised 6 weeks, but it will void your warranty :ford:

Most likely Aero; another thought is an R, in spirit, isn't supposed to have a condenser. But that would mean the R w/Elec. should have the Non-R restrictor plate, which I don't believe is the case.

I bougt a "spirit" R ; ) The "spirit" R oil preassure without the additional accessories is lower than that on my track pack. Additionally my base R is definitely quicker and lighter on its feet. The difference is measurable and felt by the butt dyno. So I definitely think its becuase of the pixie dust lololololo

Your noted oil pressure reduction (in your "spirit" R - hey, I'll take credit for coining a new term!) is most likely due to differences in tolerances and clearances within the engine components which are part of the oil flow circuit. I don't think the external accessories should have an impact on oil pressure. Pixie dust, on the other hand, has been known to cause amazing things to happen...so says my 8 year old daughter...
