The rules move over from the other class rules. I was able to get them to add the 16 inch designation.. past that.. we'll see after the event of others that may want larger rims.. and the issues of having a larger contact patch.. Guess its to try and keep everyone similar.. whether beneficial or not. And keep tire sizes down as well. I was suprissed they allowed slicks on a street car class... thats ok.. plenty of wheels and tires for sale.
Razor,
The Turbo Alcohol Rules for the GS Nationals have been revised. I've included the newly revised rules below. The official 2006 rules can be seen on the GS Nationals Website. Thanks for your help in promoting the new class, I hope we have enough cars to keep this race class alive for 2007.
Thanks,
James West
2006 Turbo/Alcohol Injection Class Rules – T/A
Official 01-20-06
Race Class Objectives
The Grand Sport Club of America would like to see the return of a reasonable, grassroots, regular-guy shootout of legitimate street driven Turbo Buick or Pontiac Turbo Tran-Am cars. This race class is being developed to show the potential/benefits that alcohol injection systems when used with 92/93 octane unleaded premium pump gas can have when installed on a Buick Turbo Regal, Grand National/GNX or Pontiac Turbo Trans-Am.
*This race class is being run on a trial basis for the 2006 GS Nationals only and may become a regular class thereafter.
What Can I Win
The first award will be presented to the entrant that posts the most consistent e.t. based on an average of the best two (2) out of three (3) quarter-mile passes. The second award be given to the entrant who posts the quickest quarter-mile elapsed time (e.t.) and the third award will be presented to the entrant who posts the fastest quarter-mile per-hour trap speed. In the event of a tie in average e.t., average mph will be used as a tie-breaker. Entrants will make a minimum of three (3) and a maximum of five (5) official passes during the event.

Pre-Race Technical Inspection Requirements/Instructions
All pre-registered entrant’s cars shall assemble as a group to be tech inspected based on the General Rules established above. The technical inspection location shall be at the GS Nationals host hotel parking lot on Thursday, May 18, 2006 beginning at 9:00 am and ending at 10:30 am. Entrant’s cars must arrive at tech inspection with the gasoline fuel tank at or near empty. Each entrant’s fuel tank must be able to accommodate a minimum of 10 gallons of 92/93 octane pump gas during the filling procedure. ***NOTE: Each entrant’s gasoline fuel tank must not contain ANY leaded racing fuel or additives such as xzylene, ect! See Race Day Format below. After the tech inspection, under the supervision of the Turbo/Alcohol Injection Class Tech Inspector all cars will be driven as a group or in groups to a designated gas station where each entrant’s fuel tank will be fueled with 92/93 octane unleaded premium pump gasoline at the entrant’s expense. After the tech inspection and fueling, entrants are free to proceed to the track to make as many quarter-mile passes as necessary to tune their cars prior to the first of the officially timed quarter-mile passes to be held on Friday evening, May 19th. Cars must weigh at least the minimum 3,500 lbs. w/driver prior to the start of the officially timed passes. Weigh-in time and place for the T/A class cars will announced at the tech inspection.
***NOTE: NO ADDITONAL GASOLINE FUEL MAY BE ADDED OR REMOVED FROM THE CAR’S FUEL SYSTEM BY ANY MEANS AFTER BEING FUELED AT THE TECH INSPECTION.
Race Day Event Technical Inspection Requirements/Instructions
Prior to the first round pass, all Turbo/Alcohol Injection Class entrants will assemble in the Beech Bend circle track staging lanes for a brief drivers meeting; each entrant’s alcohol injection system reservoir must be completely drained of all contents. At that time, the Turbo/Alcohol Injection Class Tech Inspection Director will witness each entrant fill their reservoir with alcohol i.e., methanol, isopropyl, denatured, etc. from a commercially available, marked, un-opened/sealed alcohol container. Alcohol injection system pump lubricant from a commercially marked, un-opened/sealed container may also be added at this time if needed. After the reservoir is filled, no further additions will be permitted during officially timed event quarter-mile passes. All cars must return directly to the circle track staging lanes after each pass. Failure to do so will result in disqualification from the event.
Race Day Format
Dragstrip race format will be random pairings of side-by-side runs on a 5/10ths sportsman tree. Driver lane choice will not be allowed. The Event Race Director reserves the right to conduct single-lane passes in the event of a condition that prevents the use of one lane. Following the completion of each run, competitors must return immediately and directly to the circle track staging lanes until all officially timed passes are complete and after their final pass. Entrants unable to complete all officially timed passes will be listed as DNF and any entrant returning to their pit area before the end of the event will be disqualified.
WARNING: ***Gasoline fuel samples will be taken at random from entrant’s fuel system during the timed runs and from the three top award winners and runner-up at the conclusion of racing event. These samples will be analyzed for lead content and octane rating. Any entrant’s gasoline sample found to contain lead or have an octane rating that is above rule specifications will be disqualified and will forfeit all awards.
I'm going to have to address this problem STAT.
