+2, great video, and yeah, it shows the track very nicely

It can be, yes. Canada is another corner where braking earlier & softer, and starting turning in with gentle, slow hands, is really the fastest, most stable way through.

Oh, yes...by far.

can you put the 4.0 engine in it now?

I realize I am miles slower than everyone else...but I too felt that when I started braking earlier for Canada (so could be smoother), I could be on the power sooner through the turn and surprised myself how much faster I was at the top of the hill (tracking out in the parking lot). Similar for Turn 1, braking sooner and shallower (if that's correct terminology) I could carry more rolling speed through the apex and be on the power all the way through to Turn 3. Rather than, in both instances, braking super hard and late and then having to commit 100% focus to controlling the car through the corner rather than being on the power. I noticed me being smoother let me be faster through consecutive corners...at least for me being a beginner

It also helped to switch out of 10 month old MPSCs, and not have a flat front tire Next up is to have my wheels aligned in the correct direction.

Its not that exciting, 996 turbo blow up, pukes oil in T-2, 3....I go for brakes and there are none.....car gets sideways and the grass is the only place to go

I'll look for it

Yup! A lot of it has to do with where the mass of the car is moving during that transition (braking, followed by turning). if we can reduce the drama of the first transition (IE, brake more softly, thus not pitchhing the car on its nose & heavily unloading the rear tires), the second transition (lateral) works a LOT better, with huge increases in the amount of all 4 contact patches available throughout the corner, and much better suspension compliance in order to get the power down.

Um.. Indeed. I braked so much too late! The exit of Canada corner was soo slippery, even when taken right. Is it always like that?


As you found out Canada Corner can be quite slippery. Late braking can be very exciting there. It is not always like that but more often than not. It can be a really exciting track after a vintage weekend event with those cars dropping all of their various fluids. Canada is one corner I have never felt completely comfortable with. Seem to be too slow or too fast. Rarely seems to flow. 13-14 is really fun though although I liked it better when the bridge was in place (though much safer now.) Enjoy Mosport.

Crossed the border and changed all the gauges metric. 3 hours until Mosport!

OK lets be fair to the 12C. First there is a known door latch issue that I ran into at RA. It's the first year for the car and the first time McLaren has made a road car in many years and this is the first issue (in 3k miles) of any kind I have had. The car has been perfect. As stated, two techs jumped in a car and drove 2.5 hours from Chicago to fix it.

Second, the car did not overheat. There are bar graphs that show oil and water temp. The oil temp would go yellow after four or five laps and the water temp did the same a couple of laps later. There was apparently a little too much coolant in the car and it puked out a very small amount the first session and never again. I should have contacted the McLaren engineers right away but instead I'd just run the car until the oil went yellow and then pass through the pits or take a slower lap. When I did email the McLaren engineers (try that with Porsche) they said the yellow is set pretty low and not to worry about it on the track but to obviously watch to see if it was climbing or going red. They said if it was just tettering on yellow, which it was, it was no problem at all.

So, my impressions of the 12C. Between my GF and I we've owned a dozen Porsches and I have a lot of race miles on a 996 stock class car, a 996 cup and a 997 cup in both PCA and a few IMSA Patron so I'm still a die hard Porsche guy. Having said that, the 12C is a crazy fun car. The fit and finish are perfect and the car is rock solid. We drove it 350 miles to RA, ran a pretty easy (I can't afford to wreck it) 2:27 on Pirelli street tires, packed up and drove it home. As mentioned above the support for the car is amazing. I'm saving a text from McLaren engineering giving me suggested cold track tire pressures. Like I said, they responded immediately to my question about the oil going yellow with a bunch of questions about air temp, top speed, etc. and then got back to me in minutes with the don't worry, drive the wheels off it and get back to us on how it performs. Unfortunately I had already left the track.

It as great to see all the RS's at the track. Have fun in Mosport guys. Its the best track in NA.

To the mancation crowd coming to Mosport - this is exactly what pro David Empringham does going over #2 and #4 - he actually enters #2 and #4 much faster than you think is possible and carries the brakes right over and down the hill and avoids triggering ABS or unsettling the car (it is really amazing when you are in the car and see it done) - the car is extremely balanced as he does this (you feel like you are perfectly balanced on the 4 tires) - then once he gets it set (it feels almost delicate) he then has so much more grip he goes WOT way earlier than you think is possible - this was the most shocking thing to me - it was done in my car, I couldn't believe the grip the car had going down #2 - it was quite frankly unbelievable as I didn't think the car could do what it was doing - (don't try this and total your car - i'm just telling you what he did) - doing this technique basically in #2, #4 and similarly in #8 was how he did the lap 3 seconds faster than I could (and I was in the car to boot)

aussie jimmy

yeah that empringham bloke is pretty good.
he drove the sierra sierra time attack evo out here the last couple of years. didn't win, but close.

Veloce Raptor

Yup! And this applies to pretty much every track & every car I have ever ridden in and/or driven!

Those spring rates do not look very confidence inspiring, which means a lot when driving a Turbo, Rear Engine, RWD car. Car seems like it would dare you to get on the throttle early exiting a corner. How does it feel to you? What kind of lap times do you run in it?

Izzone

I drove it, it was tail happy in slow and fast corners

Had to keep car out of boost by taking the car a gear higher to keep it from swapping ends

drdrank

Ah, I get it. Thanks for the great explanation of what the car is dynamically experiencing. Is there a balance to be had here though in other situations where it might be better to brake later/harder? Maybe in situations were you have consecutive slow corners where you couldn't put power down anyway so is it better to maximize the prior straight? Like the left hander (turn 4 maybe it is) at NJMP Lightning and the left hander (turn 5 maybe) at NJMP Thunderbolt...is it better to elongate the acceleration on the prior straights in those situations and brake later, since you can't go anywhere fast in the subsequent corner anyway? In both those corners, it seems like some people brake too much early on so they can be fast in next corner. You can catch them by staying on the gas, of course having to brake harder but the next corner after is slow anyway so you're still ahead.

Sorry about the bad luck but I'm curious doesn't the tranny implode first in a "money shift" in order to protect the engine? Engine is toast but the tranny is still good?

Intersport...specialists in rebuilding?

Best of luck with rest of trip.
