Sæsonen er ikke ovre endnu for Johan
Johan Schwartz skal køre Camaro TA2 på CotA
Den kommende weekend stiller Johan Schwartz til start på Curcuit of the Americas i TransAm serien, hvor han skal køre en Camaro i TA2 klassen. Han flytter sig dermed fra den ene ende af skalaen indenfor model og motorkraft, da han ved sidste løb kørte Chevrolet Sonic, men holder sig dog i GM familien.

Kurt Roehrig, holdejer og opfinder af det magnetiske støddæmper dynamometer, kontaktede for nylig Johan for en aftale om at han skulle køre Roehrigs TA2 Camaro. Kurt er vild med alt inden for racing; og udover at have grundlagt Roehrig Engineering, var han også team-chef på det BMW-drevne Mach 86G, kørt af Davy Jones og John Andretti. Han konstruerede desuden Tommy Kendall's Trans-Am vindende Chevrolet Beretta.

"Da Kurt spurgte mig, om jeg var interesseret i køre hans TA2 Camaro på COTA, sagde jeg til ham, at jeg ville tænke over det og vende tilbage i løbet af en uges tid. "just kidding" - selvfølgelig sagde jeg ja med det samme," fortæller Johan Schwartz.
"At få den slags opkald, fra en person af Kurts kaliber, betyder meget for mig. Kurt, med sin ingeniør baggrund, og det hold han har på plads omkring bilen, er alle top professionelle."

"Mit mål er at få gjort bilen så hurtig som muligt under testen, køre et rent løb og få et godt resultat, som Kurt og teamet vil være stolte af. I indeværende sæson, har jeg arbejdet på at gøre en forskel, ved at køre for Prostata Cancer Awareness. I Camaro #04, vil jeg køre for en anden sag, Parkinsons sygdommen."

Kurt blev diagnosticeret med Parkinsons for fem år siden og bruger hans team til at bringe opmærksom om sygdommen, som mere end 60.000 amerikanere diagnosticeres med hvert år. Dette antal inkluderer ikke de tusindvis af tilfælde, der aldrig bliver opdaget.

Tidsplan for løbsweekenden: 4.-7. november:
Onsdag: Test
Torsdag: Officiel træning og "Fast 5 Qualifying"
Fredag: 2nd Chance Qualifying
Lørdag: Løbet starter kl 16:00 lokal tid (søndag kl 01:00 CET)

Johan Schwartz forklarer her om forskellen på de to biler:

The little restrictor plate - choked four-cylinder Chevrolet Sonic is a bit different than a thundering V8 Trans-Am car with a torque curve that can pull most stumps out of the ground.

However, when racing different platforms, you have to step up, adapt quickly and make it happen. It is important to be able to change your mindset to the car you are racing next.

So what are the differences between the Sonic to a Trans-Am Camaro?

It's hard to believe, but the cars weigh almost the same and both are Chevrolets. They both have a steering wheel and four tires to manage, and both are a blast to drive....and the similarities pretty much stop there, as they are very different.

Platform
Camaro TA2: Tubular chassis, just like a NASCAR Cup Series car
Sonic: Production-based chassis

Drive
Camaro TA2: Rear-wheel drive
Sonic: Front-wheel drive.

Weight Distribution
Camaro TA2: 49% front - 51% rear weight distribution
Sonic: 60% front - 40% rear weight distribution

Suspension
Camaro TA2: Coil-over spring package, with custom-made shocks and a plethora of spring combinations
Sonic: A fixed spec package, with spec springs and shocks

Engine
Camaro TA2: 500 rumbling horsepower from the LS3 platform
Sonic: A little over 100 with the restrictor plate

Brakes
Camaro TA2: Fully vented brake rotors with no ABS racing calibers
Sonic: Stock brakes and calibers with ABS, racing pad allowed.

Transmission
Camaro TA2: Dog gear box where the clutch is not needed for up and down shift, just a little lift to release the engagement of the gear, and bang, you are in the next gear in a blink of an eye. It makes it possible to left foot break while downshifting. Still have to blip throttle to match RPMs. Possible to change gear ratios.
Sonic: Standard synchro transmissions with a fixed gear set and you have to be gentle while shifting so you don't wear out the synchros,

Racing Line
Camaro TA2: In some corners, a later apex is more beneficial, as the driver has the power available to accelerate and open up the corner with a bigger radius on exit.
Sonic: Maintaining speed through the corner is more important, with constant radius through a corner, or sometime an early apex to maintain entry speed - hard for the little Sonic to get up to speed after you take it off.

Considerations when driving the Camaro TA2:
• Tire management is very important in both cars. One needs to make sure there is some tire left toward the end of the race.
• The Roehrig Trans-Am Camaro is not a big fan of trail braking, as we run a soft spring package and can overload the tire, so much of the braking is done in a straight line and only a tiny bit of braking on turn in in. Flat platform and tire friction circle is super critical.
• The tire on the Trans-Am car is a bias ply tire, so it can handle some pretty substantial slip angle and still retain grip. The driver can't overdrive the tire as this 100-mile race puts some strain on it. Again, tire management is critical in insuring you have some tire left towards the end.

Ever since the first Trans-Am race I saw in the streets of Dallas in the '90's, I have been intrigued by these cars and wanted to race one! I am impressed by the technology in the new GTs in the same way I am intrigued by the ground stomping, pushrod V8 with traction control determined by your right foot, and where optimal braking is determined by your foot and not by ABS in the Trans-Am cars. This type of racing is as American as it gets, and I can't wait.

If it rains, I will be very happy, as I like racing in the rain and won a Pirelli World Challenge race in the rain at COTA earlier this year.

When you get a call like this, are no excuses. You step up, adapt quickly and make it happen. I am always up for a challenge, and one should always be prepared when an opportunity like this comes up.

I am looking forward to adding the Camaro TA2 to my racing resume.
