For you road race guys
In car vid of a practice session at the Autobahn Country Club. The fastest car of the day was a Porsche GT3 Cup car that was running a 2:32. I was knocking out 2:40 in lap traffic with a great deal left on the table This was our first testing at the track with our 96RT-10 Road Race Viper. 3400lbs race weight & 500rwhp. The slicks I was running were 6 years old but still had a little life in them. With proper tires and a clean qualifying lap I think we could play beneath 2:35I left the vid go longer because I wanted to show the team units that are being built around the track, the timing and scoring and general members building in the pit area. When exiting the track (pit in towards the end of the vid) you'll see a large team unit building (10,000sf that is owned by a member) that will house road race toys and be used for his personnal entertainment. There will be a total of about 40 member owned team unit buildings around the perimeter of the track. The track is awesome and when the entire facility is built out the ACC will be one of the coolest road course facilities in the country. The vid is 26meg but you can stream it if you don't want to download it Autobahn Practice Session |

Ron
I enjoyed all ten minutes of your track time. Where is this track you ran? It sure is flat and I didn't notice any off camber turns. Speaking of turns, there's a lot of them. Too bad they don't have a least one good long straightaway so that you could really let the legs out on your Viper. Didn't seem like you ever got to use fourth gear. And, you do love to get up on those curbs. I saw some pretty quick steering when you got the car upset doing that. The fellow racers looked very aware and courteous, though the guy in the BMW made you work for it a little to get by him. Too bad you couldn't go out and run with the next group that was sitting on the grid. You probably would have had more fun with the Formula car and the two sports racers. Now get you some new tires on that car and go tear it up. |

Heh, Ron Hunior, appreciate the posting as my son and I thought we were going to make an SCCA later this month, but ye olde schedule wouldn't allow (of course the fact that they are only running the 1.4 mile course also held sway ). Looks like a technical little beast, and your brief runs into fourth, suggest you only got to around 120 a couple of times? Looks like good run off areas, and it should be super safe if the rumors that Viper Days will be there next year transpire.
Appreciate you taking the time to show us all around, and I figure with new tires you could be down , to say..............uh, a 2:31!!!! |

The Autobahn Country Club is in Joliet IL., 2 miles west of Route 66 Dragstrip. The track is brand new and there's a great deal of info on their website Autobahn Country Club I was running a 3:73 gear and hitting close to maybe 5200? in 5th gear. Coming out of the turns I was in 3rd and never went below that. The longest straight is the one in the very beggining of the vid and it's 1850ft. The next straight after that is 1600ft. They're nice straightaways but at the end of both they pitch down and don't allow you to carry as much speed all the way to the turn. Besides the tires being old they were also a different compound from front to rear. Everyone at the club has been very courteous on the track during sessions and while hanging out at the facility. Mark Boden (owner of Fall-Line Motorsports) was driving the BMW and is a very accomplished racer in SCCA. George Biskup is also a member and was there driving his Mopar sponsored SRT-4 T2 rocket. If you look close, one of the the sport racers in the next group is a Ferrari 333 I don't think I would have seen much of him but maybe the others This was only my first practice session at the track in the Viper and I was being overly courteous myself. Next time I run with new tires I won't have time to wave while I'm passing |

Ron looked like a great time, it was great to see you blow by all of the Porches. What was the first car you passed in the video, a Boss Mustang??
Also I noticed some good fish tailing around corners, is this pretty normal for the Vipers? It's very easy to do on the street, but was just curious about it on the track. Also I really like the rear view mirror setup, as I'm starting to find that the factory mirror location is a blind spot. Cal |

Ron With the 3:73 rear end I understand why I misread what gears you were using. Anyway, it was great to see you have such a fun time on the track. I still can't get used to the braking points I see people use in these cars. I'm always saying to myself "you should go deeper into that braking zone" but hauling in 3400 lbs of car versus a 950 lb. formula car is a whole different game. Make sure to post your video when you run with some new tires. |

The fish tailing was due to a few things: I was testing as much as I could while practicing. Turning in early, late, bouncing off the curbs and testing the edge of the car. Finding out what was there and where I could go gave me a good idea of what the car/track had available. A few of the tighter/shorter turns I needed to be more patient. I was working on getting full throttle by the apex and couldn't quite get there. This Viper also has an extreme lightweight flywheel and 7 1/4" triple disc Quatermaster racing clutch pack. Shifting and getting in the throttle is quicker but can get you in trouble quicker too. It's difficult but alot of fun trying to figure out all these things in one session. The tires are 6 year old Dunlop slicks that are different compounds from front to rear. The front had more grip and the rear was unforgiving. The front stuttered when you found the edge of traction and the rear was like no warning slipping on ice. The overall balance was timid and nothing close to being on "rails". The torque in the Viper is great for getting out of the turns yet it's a balancing act of smooth delivery to the throttle. The mirror helps tremendously and allows a much quicker asessment of your surroundings. Once you use it on the track you'll always want it in the car |

Very cool, especially to see a Gen 1 dash.
What kind of brakes? I think lots of what was left on the table was under braking, too. |

Actually Ron, if the track is 2.4 miles long, was it actually around 1.31?
Just trying to figure as you mentioned you were getting into 5th ,and a 2 minute time 31 second time is about what a good running stock Viper can do around the 4 miles of Road America. |

First of all I like to say thanks for sharing that video! I wish there was more video's like this. If you have anymore, especially race vid's, please post them. When I'm not driving or racing my Snake I love to watch these.
Thanks again! |

The master cylinder sizes on the 2 seperate master cylinders (front and rear) were sized for a 4 piston brembo race caliper in the front. I installed the bigger calipers in the hopes that they would be better but the bite was less. I did get quite a bit of "milky" looking fluid after they were bled that indicates some water in the system. The pads are an older 83 compound yet they should pop your eyes out under braking After making all the necessary changes from the shakedown runs I think we'll get great improvements under braking The goal is fast in fast out and everything needs to be in harmony to consistenly produce those results |

It's the full track (3.56 miles) I now have a great reason to be there 7/23 and it's marked on my calender. The south course is more technical than the north course and it's easier to have an OCE, yet the runoff is all safe. We need some Viper Speed to show up and have the equipment to hunt down all the Porsche GT3's Look forward to seeing you there! |

Wow, now I am excited , as everything I read said the long course was only 2.4 miles long, not over 3!! Sounds real fun now, and I will definitely be there if Viper Days has it scheduled next year.

Ron:
Glad to hear you'll be there on 7/23 as we'll need someone to show us the fast way around the South course. We should have the '97 GTS, the '03 CompCoupe, and the SRT-4 with us. We raced the Vipers against GT-3's at Sebring and found them to be very formable competition... For those who don't know, Ron's little 'ol '96 RT/10 is one bad-a$$ machine. All the right road racing goodies, plus a whole lotta motor! See you shortly, Rich |
