IMSA Race TUSC Round 8: Mosport

[joeb]

This weekend has slowly crept up on me. We have only 3 classes this round with the PC cars staying home, should be a tight fight in all classes.

Hadn't snuck up on me. Here's my errant post from your competitions thread :

I'll say this one time for Ron Fellows benefit cause he's a nice guy... Canadian Tire Motorsports Park. "Canadian Tire, for all your Canadian tire needs."

I will watch any race at Mosport. Definitely on my short list of tracks I'll be visiting soon. I will be shocked if Oak doesn't dominate as Mosport is the definition of a high downforce track. Hopefully they're gluing winglets all over it now.

Winglets....and backup winglets.

It's going to be a Corvette Coral in GTLM...

Ford's boost press BoP help is apparently for altitude compensation... sure

+0,4mm restrictor

Oh and no one is calling this place CTMP but Fellows and marketing people, no one...

I still cry they 'had' to ruin so many of the iconic corners with asphalt runoff, it's such unusual action for relatively low profile track in North America which doesn't even get visits from series that "require them by law" (even NCWTS shouldn't be the reason). I guess the bikers moaned for something

I will pick the Dodge Vipers to take GT and the Morgan Nissan in prototype. I think this race has a good chance to go full course caution free.

How about the sprint Ligier LMP2--that thing in sprint trim has diveplanes that would put HPD to shame.

Even the Audi R18 2014 sprint diveplanes put even the DP's and HPD's to shame with how effective they are as both downforce producers in unison with the bodywork and as vortex generators (main reason why even LMP1s run "trim tab" diveplanes at LM).

Ten-Tenths supported IMSA Spotter Guide up. Does include the NGT entry which has now been pulled. btw - MSR reverts back to Aero livery this weekend as per the guide.

Im rooting for the snakes again. Dont care for the prototype battle much.

[Maelochs]

There will be a prototype battle? Besides fighting over BoP?

I haven't seen a BoP downgrade for Corvette (haven't looked much) but without it ... Corvette in GT again. The Vipers were fast at the Glen but not up to the Vettes' pace.

[Rodger Davies]

Regardless of what you think of the BoP, there will be a prototype battle, yes - even if just an inter-DP one.

Personally, I'm thinking that so long as the Oak car stays on the track it will absolutely walk this one, and its biggest threat is likely to be the Dalziel/Sharp car.

The back straight is pretty long and the DP's have a higher top speed. What's to keep them from breezing by the Oak on the long back half of the track?

This post is too reasonable to be allowed.

The first high-speed-corner-section of the lap. At Watkins those were inverted, with the straights first, which is the only reason Westy could make a quick pass. You're forgetting that the P2 was a second quicker over the rest of the lap. If it has that lead before the straight, which has fast, flowing corners after it, should be a different story.

Might be worth the P2 teams scrubbing the outside of the turns during practice sessions.

That is actually a good idea!

I agree it should be interesting.

[Maelochs]

Oak can't establish an advantage into the twisty first sector if it starts from the pole and ends up fourth or fifth by the first turn ... could that even happen, though?

[HighParker]

They should now be setting up the promo/display event at Dundas Square in Toronto from 11 am to 2 pm.

[Accident]

I'm still not fully convinced there is anything wrong with the Corvette's BoP in GTLM. I don't know average lap times so they might have a real speed advantage I guess, but according to best laps in the races and qualifying they aren't necessarily the fastest.

They got another win at Watkins Glen because they got a good start and put a car in between them and the rest of the group, and had what seemed to be a perfect race. No penalties or pit stop fumbles, and we didn't see any offs or anything on the coverage.

There isn't anything wrong with the Vette's BOP. It's just a very well done car. That doesn't make anyone in the field happy. Bobby Rahal says the Corvette's will race themselves this weekend.

Don't think the run to the first corner is long enough.

This'll be a fantastic race, imo.

I agree with the asphalt runoff...they should have kept a two foot section of grass between the track and it, if they had to have it.

[fieldodreams79]

No matter how long the run to the first turn is, DPs are just too quick on cold tires and the LMP2s, I mean, Oak get outbraked time and time again early in the proceedings. Even still, this WILL be fantastic but I suspect many FCYs will interrupt the action quite a bit.

As others have alluded to, I'll watch push carts at Mosport but this DID sneak up on me. Too much going on around me these days but I know where I'll be Sunday.

[Rodger Davies]

How much do you have to brake in the first few turns at Mosport though?

Will be intriguing as to how the DPs handle the first couple of corners.

I'm sure he would say that. I still remember a few years ago with the M3 when they *****ed about a restrictor change "killing our straight line speed" and then went to Road America and were the fastest cars in a straight line.

The Z4 should do pretty well at Mosport since most of it is a handling/downforce track. The gaps in GTE are a bit smaller though, so whether or not the handling strength is enough to make up for the straight line weakness in the race is a bit of a question.

It isn't. The whole front straight is pretty short. I just had the pleasure of being passengered around in a somewhat tricked-out Mustang Cobra, which admittedly is no prototype, but even in that car the front straight flies by pretty quickly.
