Rookie? No one here will call you that, finishing just one spot out of the trophies on your first NASA Nationals. Very impressive my friend and I look forward to seeing you at Autobahn in October. I will be the guy with the long rope and grappling hook , hoping to snag the back of your wing so I can stay somewhat close to the Grey Beast!!!

Super impressed with your run and no need to be so modest, 4th is fantastic at the Nationals -- wow!!!!!

Nick, just wanted to clarify the incident going into the Keyhole. Brian was leading the race when on lap 2 his coolshirt box strap failed, dumping water which caused a snap spin in the carousel. He slowly drove through the grass to get back on track, (which apparently still covered his brake ducts), which dropped him back to 6th place. With no indication of a problem he worked his way back to 3rd with his sights on 2nd. Hitting his normal brake point he found a hard pedal and no stopping power. 1300+psi brake pressure and cooked brake pads.
Glad that you were not involved, and thankfully heads up driving by the other driver kept it from being a worse situation.

Nick,

It was awesome to watch your racing skills at Gingerman! Also spending time with you at PITT.

Keep in touch as I'll gladly tag along to help out as pit crew next season!

As I said, the car mods have begun.

Going with a stiffer spring package. Swapped out front and rear springs, and going to lower ride heights:

Taking a short break in Boston over the weekend — hoping to have time to make some Aero tweaks next week before the race at Autobahn.

 

[Black Boss]

Added a couple of Aero tweaks:




Also changed out the front rotors, ready for the weekend:

Fender vents looks awesome! who makes them?

Fender vents looks awesome! who makes them?

They're not a Mustang part. It's the Hood Louver Kit for the Golf R / GTI from Verus.

You need to modify them to vent out rather than in and they need to be bent to fit the fender contours.....

 

[Black Boss]

Finished modifying the Verus diffuser to fit the 350. Added the Diff cooling ducts:



And some modifications to brackets either side. Epoxied the spacers to aid installation and added exhaust heat protection for the powder coat - it’s very close to the mufflers:

 

[ddozier]

Looks good, now while you are wearing your fabrication hat make one of these and extend the diffuser to the center line of the rear axles. It will make the diffuser more effective by cleaning up the airflow before the diffuser. PM me is you need a cad file to have one cut or I can have my guy cut one for you.

@ddozier Dave, Very nice! I need to look at my exhaust runs, and will PM you later. Thanks!

Here's a better view of the second corner "Mayhem at Madness" -- NASA Nationals ST2 Start:

 

[Black Boss]

So the spring rate increase, lower ride height and minor Aero improvements paid off.

Great times with @Bill Pemberton @TMSBOSS and @BOSS302r013

Congratulations! And a few more photos earlier from our ace photographers at the race.

 

[Black Boss]

Need to unlike one of those photos.

No way Nick! Who doesn't love a plumber butt photo???

 

[Black Boss]

More mods planned. Need to loose some rotating mass and improve durability, looking to get a few more 1/10ths on track:

 

[ArizonaBOSS]

That is some serious clutch hardware. Hopefully it is not on/off engagement like a stock car. Really like the more robust TOB, as well.

 

[Black Boss]

Yep, I’ve had a few slave failures on the stock setup. Like the more robust version with a bleed line.

 

[the5]

Looks like the Gt4 Setup, Correct?

 

[Black Boss]

No. The GT4 uses a Holinger Sequential Gearbox and the clutch is only used for initial engagement.

Would love to go with the Holinger, but it's a lot of work, and I'd have to take a weight penalty for ST/TT2
