@949 Racing how do you like the GT350? Quite a bit heftier than a Miata...even a SUPERMiata...

Haven't run DDT, but the organizers of the event were talking about splitting the day between DDT and the Main track in future. How do you rate DDT versus the main track?

Oooh, Tremblant - such a fun circuit! I'm going to be there for the club endurance race in August.

How did the GT350R get past noise restrictions? We had to put the quiet mufflers on our 458CH last the we were there, which costs ~40HP

It failed noise by over 3dB. Plus they move the microphone location, and do not disclose where it is, so short shifting only worked on day 1.

Ended up disconnecting the exhaust valves, as they default to closed. Fixed the noise, but you can't select Track mode with them disconnected. So net result is you have to run with Sport damper settings and obviously the car is down on power......

They aren't really comparable. DDT is slow(good for learning) and the GP track is a world class circuit. I only live about an hour from Mosport so running the DDT offers a unqiue venue to the Time Attack series. Given how far you're traveling it woulld be a bit of waste to run a split day between the tracks. Our series runs a weekend on the GP track once a summer (back in June) where we host a school on Saturday and event on Sunday. I'd suggest it would be worth your time to come back next year for this and the pricing is pretty good as well.

comment: this was a 101F day. bone stock GT350. bought 1 week prior. still has original oil. stock PSS tire is good for 1 lap only. 2nd lap on, it is 1+ second slower. cooler weather would drop it by another 1.5 second easy. Car track nicely, only issue was high oil temp - 290F

 

[VoodooBoss]

@Bellwilliam how were your diff temps? Mine have been close to 270 on 100 degree days.

 

[Bellwilliam]

I wasn't sure. First time one track with the car, I was watching for oil temp. I didn't check for diff temp till after cool off lap and 5 minutes cruising around paddock. It was 230F by then. So it is possible diff temp was super high. I will check next time

comment: this was friend's car, was a 101F day. Same day as prior post. bone stock GT350. He bought 3 week prior. still has original oiL. He installed RS4 tires on 6GR wheels (0.5" wider) handles heat much better than PSS. it goes away after 3 laps. Had passenger. Car tracks nicely, only issue was again high oil temp - 290F

Streets of Willow CW. About 1,000°, crikey. Later on William (Bellwilliam) did a 1:23.96 in my car on RS4's. We think the same setup would do high 1:21's in say, 55° weather. That's stupid fast for a stock car on this track.

Me chasing William. He was thinking about getting one but on the fence. At Sonoma I twisted his arm to drive mine (he was worried about scratching it!), he was convinced.
That's his Grabber Blue on PSS I'm chasing. His tires had gone off, my RS4's were then probably 3s a lap faster so I'm poking around trying to aim my car for good video.

Hey Florian. How did the tires feel?

Hi Rob,
Those were not yours. They were a set I bought earlier. They almost lasted the whole 3 days (~10 sessions). The fronts corded before the last sessions.

I had a hard time figuring out my hot pressure. It's hard to get an accurate reading due to the length it takes to go back to the pit.
I'll have to fine tune the car to get most out of them but initial impression is very good.

 

[cobrarob]

Sounds good,hopefully next track day you'll get the temps quicker. Can't wait to try those tires next year on the Apex11"s...
Hopefully you got some vids to post

My second time at Sonoma Raceway and first time on 305-315 Sport Cup 2 tires. I ran a 1:57.7

I think my personal best last year on the MPSS was somewhere around 2:09

Still trying to get a video of the lap. Hopefully within the next few days. My computer has been crashing like crazy trying to process it.
