how fast and how high rpms can i go in my new frs?

[10series#1969]

first new car i got some dumb questions
what is breaking in a engine or transmission?
why do u need to do this
how do u know you've broken your engine in?
can you down shift?

thanks

[kALMIGHTY]

No, no down shifting allowed. For the first 1000 miles, you must continue to upshift.

thanks

Now that I'm done being an ass (lol)
Breaking in the engine basically means you're "priming" the parts for proper function later on the vehicle's life.
By taking it easy for the (recommended) first 1000 miles, you're giving the parts to settle into their "resting" position, letting them get comfortable with what they have to do in the future. At least that's the way I think of it. Sort of like how new shoes are always uncomfortable, but after wearing them, over time, they become softer and more comfortable to wear, and they fit your feet better.
Just keep the engine RPM's under 4000 for the first 1000 miles and that should be enough. A lot of people here still disagree about whether or not it actually helps or not, but it was in the manual that came with my car, so I followed the instructions. No downside to following the rule!
Enjoy your car.

right on you pretty much answered my question. thanks!

@10series#1969 This is kind of off-topic, but I see that you are located in Hawaii.You should definitely check out the regional forum we have on here, would love to be able to see you at one of our monthly meets (this month's meet should be the 28th). Welcome to the club, and congrats on the new ride!

Porsche Cayman Break-in Instructions

2,000 miles/3,000 kilometers



The following tips will be helpful in obtaining optimum performance from your new Porsche. Despite the most modern, high-precision manufacturing methods, the moving parts must still wear in with each other. This wearing-in occurs mainly in the first 2,000 miles/3,000 kilometers.

Therefore:


· Preferably take longer trips.


· Avoid frequent cold starts with short-distance driving whenever possible.


· Avoid full throttle starts and abrupt stops.


· Do not exceed maximum engine speed of 4,200 rpm (revolutions per minute).


· Do not run a cold engine at high rpm either in Neutral or in gear.


· Do not let the engine labor, especially when driving uphill. Shift to the next lower gear in time (use the most favorable rpm range).


· Never lug the engine in high gear at low speeds. This rule applies at all times, not just during the break-in period.

· Do not participate in motor racing events, sports driving schools, etc. during the first 2,000 miles/3,000 kilometers.

There may be a slight stiffness in the steering, gear-shifting or other controls during the break-in period which will gradually disappear.

Break in brake pads and brake discs


New brake pads and discs have to be “broken in”, and therefore only attain optimal friction when the car has covered several hundred miles or km. The slightly reduced braking ability must be compensated for by pressing the brake pedal harder. This also applies whenever the brake pads and brake discs are replaced.

New tires


New tires do not have maximum traction. They tend to be slippery. Break in new tires by driving at moderate speeds during the first 60 to 120 miles/100 to 200 km. Longer braking distances must be anticipated.

Engine oil and fuel consumption


During the break-in period oil and fuel consumption may be higher than normal. As always, the rate of oil consumption depends on the quality and viscosity of oil, the speed at which the engine is operated, the climate and road conditions, as well as the amount of dilution and oxidation of the lubricant.

Make a habit of checking engine oil with every refueling, add if necessary.

[Porsche]

Warm up engine and drive train for 10 minutes or so before taking car over 3500 rpm. Oil should reach 170°+ before hard driving. Heavy loads, high rpms, with cold (and thick) oil can blow out seals with excessive oil pressure; proper lubrication under load requires proper operating oil temperature which is in the 170°–220° range. Our cars do not have an oil temperature gauge, so we must rely on time or distance to judge when the oil has reached operating temperature.




Tips for easy driving around town:

• Upshift at 2700–3400 rpm, downshift at 2200 rpm for easy, around town driving.
• 3rd gear best for village driving, with 2nd as needed for tight turns; 4th good at 35+ mph.
• 2nd gear for hills to keep rpms around 3000+ rpm. Do not lug the engine at low rpms climbing hills.

The tachometer, which tells you how fast the engine is spinning in revolutions per minute (RPM), is front and center for good reason; it is your most useful tool, so pay attention to it. (Be mindful of the speedometer to avoid tickets and stay out of jail. In my BRZ I ignore the analog dial speedometer on the left; I use the digital speed readout.)


Run your engine up and down through the normal rev range during break-in: 2000-4000 rpm. Make sure the oil's up to temp, first.


Avoid heavy loads. I avoid using full throttle on a new engine. As I progressively break-in the car, I use increasing throttle openings.


Yes, you may downshift; however, it is important not to change down too early and cause your rpms (revs) to rise above your 4000 rpm break-in limit in the lower gear that you select. While breaking in your new car, downshift sequentially through the gears. It is good for the engine during break-in to be on the "over-run" as you slow down; it helps seat the rings in the cylinders and promotes a good seal.

Later, after break-in, you may wish to roll up to traffic lights, in 4th gear, say, and just go straight to 2nd gear to accelerate back up to speed when the light changes to green shortly before you arrive. It's okay to skip gears like that, so long as you do not over-rev your engine.

For general downshifting to the next lower gear during the break-in period, watch the tach and shift down only when the rpms drop below 2500 rpm. This will ensure that you avoid going over 4000 rpm in the next lower gear and leaves you a little safety room.

Downshifting @ 2500 rpm:

• 6th @ 2500 -> 5th @ 3300 (57 mph)

• 5th @ 2500 -> 4th @ 3000 (43 mph)

• 4th @ 2500 -> 3rd @ 3200 (36 mph)

• 3rd @ 2500 -> 2nd @ 3600 (28 mph)

You will discover that it is difficult to change down into 1st gear when the car is rolling faster than just a couple mph. Leave it in 2nd gear and accelerate gently (small throttle openings) until the rpms are up higher. Change to 1st gear when you're stopped. Whatever you do, do not force anything.


Note: The engine will not be damaged if accidentally taken beyond 4000 rpm.



I employ the above break-in method, slow and progressive. You may wish to do so as well. Others have completely different ideas.



Is my way better?


I have no idea.


It does not seem to cause any harm, and my cars never break. Is this because of how I gently break them in?



Maybe we've just been really lucky for 50 years. I have no idea.


It's your car. You choose.

Your stock tune triggers fuel cut at 7400 rpms. As to how fast, I think it depends on road grade and your gearing. I think top speed hit stock is something like 158 mph.

[Porsche]

167 mph top speed @ 7400 rpm in 6th, were that possible, but it's drag limited to about 6300 rpm in 6th gear, which is 142 mph. Driver on the 'Net on Autobahn saw 230 kph, or 143 mph. Others have seen similar speeds maxed out, so top speed is right around there on a stock BRZ/FR-S.

Sorry, not meaning to be an ass, but this is one of those RTFM moments.


The car comes with an owner's manual for a reason...
