Super nice comment and so correct, this is a true inspiration to many! I do have to add , though, that Tyme you are going fast enough now you are no longer a Pace Car Driver , you are now , officially a Race Car Driver!!! You proved that to all of us when you were in Hastings at the 2018 Mustang Roundup. Of course you ticked off a lot of guys who you promised you would be dead last when on the track and they figured out you must be the Blue Boss Bluffer?

Always nice to under promise and over deliver.

Race Report: NASA AZ / NASA SoCal @ Chuckwalla Valley Raceway, February 2019
​

Well, it has been some time since I have driven this car in anger. Since returning from COTA in September of 2018, the car has largely sat on jackstands in my garage while I did disassembly and reassembly of all of the front end body components, including a full 2013 front-end conversion. Also during that time the car got a wrap and looks like a brand new car now!

​

I wasn't able to get the car ready in-time for our season opener in January, and other commitments at King of the Hammers kept me busy right up until the last second to get the Mustang in-order for a debut at California's Chuckwalla Valley Raceway. After our arrival on Friday night, our group of 10ish people paddocked together had a nice pot-luck including chicken wings on the grill, chili, corn bread, and chips and salsa. These impromptu BBQs are some of the best parts of the "away" events we have in other regions.

Despite my absence over the past few months, I was able to get back into the saddle pretty quickly, and fortunately the car didn't disappoint.
During Saturday's qualifying session I was able to set a new personal best by almost 2.5 seconds on Chuckwalla's clockwise configuration, putting me third overall on the big bore race grid behind a Super Unlimited TA2 Camaro and Super Unlimited Porsche Cup car. The only other guy in my class (ST2) was at the very back of the grid after posting a qualifying time about 5 seconds slower than me, so I could afford to cruise for most of the race. That driver ended up retiring about halfway through the race, handing me an easy in-class victory for my first race of the year, and my in-race lap time set a new track record in my class.

ST2 pace is roughly 4-5 seconds faster than AI here at Chuckwalla Valley Raceway

​

For Sunday, the situation was largely similar, except we reversed track direction to run counter-clockwise. I had another good qualifying session, setting a new personal best by about 1 second, and putting the car P1 overall for the day's race. I tried to get away with running an old set of R7s for the race but it turned out that was not a good strategy. A car that we upclassed from ST3 into ST2 ended up getting by me early in the race and I didn't have enough tire to challenge back. Him and I ended up running away from the rest of the race field and finishing 1-2 overall, with the next cars in race group over 20 seconds behind us at the end of the race. It wasn't a win but it was a good time and an uneventful start to 2019 for me.

​

​

And despite setting new PBs in both directions, I can already see where I can go faster after analyzing my videos. That will have to wait until next year or possibly an American Muscle Cup TT event later this year. Next event: NASA AZ at Bondurant's school course at the end of March!

Stay tuned for more...

Car looks great and obviously running great as well! That track has a pile of 180 degree corners on it, you show great patience on those corners, I find those long corners very difficult to be patient on and that does no good at all.

 

[Flash68]

Nice chronology. I had wondered about the history of the car so that was cool.

Got any in car vids of you up here at Norcal tracks?

Nice! Thanks... guess I coulda just clicked on your youtube link in your sig.

 

[ArizonaBOSS]

@Fox34 We are heading to Buttonwillow next weekend (SoCal, I know)...

 

[Flash68]

Ha... well, it's more like Central Cal.... split the difference.

Hope to run BW one of these days.... working my way up to get into NASA TT currently, so I'm staying local for now.

Good luck down there.

"Concept vs. Execution" comparison on the wrap...

 

[Grant 302]

Looks better without the V6 PP wheels.

 

[ArizonaBOSS]

I agree! Here is a better comparison...

 

[JDee]

I like the red it wears better than the mock up color, and how the red follows the one leg of the X in the Cortex logo. Nicely done!

 

[neema]

Drew when are you going flares and 335s or 335/345s?

There’s no difference in points towards ST2 class, right?

 

[VoodooBoss]

It looks terrific, I can't wait to see it in person.

Correct, no points difference. This thing barely fits in the trailer with the 315s the way I have it set up, not to mention the additional cost burden of a wider tire. But an even wider tire definitely wouldn't hurt.
I think (hope?) I am done with body mods for a bit.

 

[neema]

Hopefully no more involuntary body mods. I get your point on the incremental price hike. It's actually a notable difference between 315s and 335s. Didn't think it would be that much more (~$50 more per tire for A7/R7).

Is there a big point or performance disadvantage running $100/150 Pirelli/Michelin scrubs?

Is there a big point or performance disadvantage running $100/150 Pirelli/Michelin scrubs?

Yes, two fold: You have to take a -.5 points modifier (meaning 8.01:1 ST2 min becomes 7.51:1 for power:weight which moves to ST1, so you have to ballast back up), and typically the best cycles of those tires are gone when you get them compared to fresh R7/A7 rubber. There's a couple local guys who have run them and its always nice to know they won't be able to keep up. I have done the same when in a money pinch, but its not a competitive practice. Sometimes the winner is the guy with the freshest tire.
