Grand-Am GS Round 8 at Laguna Seca July 8-9

[Fat Boss]

Thanks for the report and photos, guys! Any new and interesting things about the Boss and/or Boss 302R you can share? To be honest, I would love to know more details about the race cars. Don't know why.

Good luck to the Bosses this weekend!

They don't use an over the engine brace like the street cars. The sheet metal seams are either fully welded or in some cases skip-welded in addition to the spot welds. This gives them all the rigidity they need. They use different struts, Ford Racing mufflers that drop 14 lbs, and no rev limit. They use two piece drive shafts to avoid vibration, different ABS logic which I think Mark said will be available soon, and a not off the shelf transmission.

Here's a link to all the pics I took. 136 pics but not all of them Ford Mustangs. http://s561.photobucket.com/albums/ss54/FatDiesel/Boss%20302/Laguna%20July%208%202011/

We need to look into lowering the splitter. A well placed source said that makes a huge difference in down force. Also confirmed the 302S hood makes a lot of difference as well.

Now I'm off to.... my niece's 1st birthday instead of going to the race. :'(

Thanks! Those are the kind of little details I love. I looked at the pictures and saw some other little details, too. In one photo, it looks like the rear sway bar is actually smaller than the stock Boss. Also, while it is interesting what you say about the front splitter, I just noticed that they don't even run with the Boss splitter, much less the LS splitter. I wonder if that is a rule compromise, or if that was by choice for aero balance. I guess spring rates are Top Secret? :-X

Thanks again for the report and photos.

Jimmy it's a rule none of the cars in the GS class are allowed to use splitters.

Okay guys, we are almost on Page 3 of this thread and the race is over. If you don't want to know about the race or hear spoilers, go away. Here is some video. It might spark conversation you don't want to hear. Seriously, go away. What are you doing in here?

Sound like you guys are having a great time. So jealous...

Feel free to post away more of that inside info from Mark!

I should have been taking notes...

Don't bother moving the battery to the trunk.
Don't worry about weight savings in the back, focus on the front.
"Massage" the "PCV-like valve" on the passenger side to flow more, prevent oil blowing out the drivers side.
Don't prioritize upgrading the rear brakes.
Steel shot in the panhard bar is for NVH reduction.
They run the Motorcraft 5W-50.
Lower the front splitter with custom cut hard foam, increases down-force significantly.

Man, I love this stuff. Still, aren't those two things up there related? Focus on front weight savings, but not the second heaviest thing in the engine room. Huh? What's the thing I'm missing? It must be something, because I can't see that anybody has moved the battery. To me, that's always like item number 1 or 2 on the to-do list.

Well Mark did say they might move the battery to the trunk for the 2012 season. The race cars are required to use stock batteries but he did caution using lightweight batteries due to the sensitivity of the electronics.

The PVC valve comment was related to his suggestion of adding an oil separator if you track your car. The race cars use a large can mounted to the firewall and both sides are vented into the can.

+1 BMWs and Camaros have their batteries in the trunk from the factory. Their's probably a reason for that.

The Challenger SRT8 I test drove also had the battery mounted in the back.
