Default Cont. Tire Challenge Subaru at Rd America

Went to the Nationwide / Grand Am race last weekend at Rd. America, but the race I really wanted to see was the Continental Tire Challenge series. I love all the variety of cars they run and closeness of the competition.
Grand Am race was fun and the Nationwide was fun to see in person, but the caution flags at the end were painful. The stock cars are just so much less cool to look at than the other two series. First time seeing Grand Am in person after several ALMS races and enjoyed them too.
The one Subie racing in the Challenge race qualified 5th and finished 6th, which is respectable at a track like this against the V8's.

Ran into two Subaru fans on Friday out taking photos. Not sure if they're on here, but suspect these were their cars.

I was there Friday evening with a group of about 10-12 other Subarus. I'll post pictures in a little bit... The white STI goes by the name Law on here and IWSTI...

Looks like their quali time was 2.25.xx about 0.9 sec off of pole time. M3's and Camaro's ahead, but faster than all the Mustangs that day.
And looks like they finished 8th. They were 6th up until the end.

The Porsches boycotted the race because the rules have been favouring the big displacement vehicles too much. Nice to see the Suby make a respectible showing though.

I was wondering about that. That's not the first time Porsche teams have done that in this series. There was one in GT, but none of the Caymans or Boxsters. 50 cars entered, but had been averaging 60 this year.

Does anyone know how they control the power output, is that subarus weakness against the 400+ hp camaros, mustang & m3. From what I gathered camaros were complaining enough got a rule change for spoilers and intake restrictor, then all of a sudden they win.

on turbo cars, some sanctioning bodies limit them by their boost and fuel. then there's usually an accompanying class rule about not opening up the block or working the heads/cams. but i don't know about this series specifically.

On FI cars like the STi and APR's Golfs they limit boost. APR actually was hit with penalty points at an event when an electronic glitch allowed the turbo to have spikes that were higher than the allowed boost limit.

On the NA cars in addition to doing it with rev limits, they do it with throttle body diameters. The Caymans are allowed to run GT3 spec TBs on them, but with 3.4l of discplacement, even with an open intake, a great exhaust, and a significantly raised redline they still can't run with the big power cars. They''ve been petitioning all season for the use of either the 997 engine or alternative gear ratios.

We're really close to getting an alternative final drive approved but until I actually make the part and have it available for sale, GA won't approve it. They've led us to believe they'll say "yes" once I've got it in hand, but it's not a sure thing and I may spend 4 months designing and developing a new product to have them refuse to sanction it. Right now. we're just rolling the dice on it...

I was watching this race on TV and was excited to see the subaru running up in the top 10. I also noticed in the background during a yellow flag there was a group of subies parked along the inside fence of the track. I though that was cool.

That would be me with the white 08, not sure of the blue one as I never ran into the person. I also don't remember speaking with anyone on Friday though

I did see someone posted my car above as well from Saturday, I did speak with some people that day.

Here are a couple photos that I snapped.

They finished 6th. If you look at the results online the first 2 cars never finished/started not sure.

Forged Pistons, 18g turbo

AST coilovers, AP rear lateral arms, Bushings all around, lots of Camber, Dry Sump, ECU

Not sure on the details but that is all I could spy from the car and talking to the guys.

Hopefully I can answer a couple of questions about how Grand-Am equalizes performance.

Every Grand-Am car uses a spec Sunoco 98 octane unleaded race fuel. Rolex and Continental run the same fuel, though it is a different formulation than what NASCAR uses. Grand-Am does set the fuel cell sizes, and does check them regularly.

All FI CTSCC cars have a boost limit, and it is monitored by Grand Am. You have to run either the stock ECU or a spec Bosch unit depending ont he car, so they can easily read all the paramters. I believe all CTSCC cars also have a mandated rev limit.

Most NA GS cars run a restrictor plate, and Grand-Am does use these as a power tuning tool. Several of the cars (GS and ST) are also required to use the stock intake and/or exhaust.

Internal engine components can be balanced and blueprinted, but have to start as stock components.

Minimum weights can be adjusted. This is probably the most commonly used.

Tire size is set by the series, and the majority of cars use the same size tires. Most of the ST cars use a 225/45 17, and most GS cars use a 275/35 18 on all 4 corners.

The Phoenix STI has done very well over the last few races, and I also expect them to be very strong at Laguna Seca next week.

Not universally. If you review the vehicle by vehicle spec list some of them must use sealed bone stock engines and cannot go inside of them.

The GS class 997 Carrera is an interesting example of this. Either, at the team's discretion, they can use a blueprinted and massaged 3.6l with the raised rev limit Bosch ECU OR they can use a bone stock sealed 3.8l with the stock ECU.

The Subaru ran 4th in the first practice session this morning at Laguna Seca. The next 5 cars behind them are within a couple of tenths of a second, so things could change by qualifying, but they are starting out strong.

They were running great at Laguna Seca but looked like around lap 40 they ended their race. Curious to see what happened as they were running 4th for the first 45 minutes.
