National Staff Greg G. Posted August 7, 2009 National Staff Posted August 7, 2009 Technical Bulletin (8-6-09): All vehicles: No-Points Modifications Section Additions: 58) OEM air conditioner system removal with or without A.C. delete pulley. 59) ABS (anti-lock braking system)--Only OEM systems offered specifically for the car model as a factory option. No OEM systems offered for a different car model or aftermarket systems are permitted. No-Points Modification List Revisions: 48) Lexan windshield, rear window, and rear passenger side windows (windshield must be 3/16" minimum thickness). (See section 7 Safety regarding front side windows.) No uncovered holes are permitted in rear windows in 2009. Holes covered with tape or other non-porous material preventing air movement are permitted. 50) SAFC or VAFC (delete "Programmable fuel systems without control of engine timing") Quote
kjbrew01 Posted August 9, 2009 Posted August 9, 2009 "No uncovered holes are permitted in rear windows in 2009 does this include naca ducts in rear quarter glass on hatch back vehicles. Quote

NACA ducts placed to bring air into the car as listed above are still ok. Quote
dans2k Posted August 19, 2009 Posted August 19, 2009 just to clarify ~ my cars Air/fuel ratios are tuned with a Apexi VAFC, thats still ok/0 points? Quote
mbuskuhl Posted August 19, 2009 Posted August 19, 2009 just to clarify ~ my cars Air/fuel ratios are tuned with a Apexi VAFC, thats still ok/0 points? No Points... 50) Programmable fuel systems without control of engine timing (such as SAFC, VAFC) Quote
National Staff Greg G. Posted August 19, 2009 Author National Staff Posted August 19, 2009 just to clarify ~ my cars Air/fuel ratios are tuned with a Apexi VAFC, thats still ok/0 points? Correct. Remember, one cannot alter settings during the competition day. So, it should be placed where the driver cannot reach it on track, and second, it should be "sealed" in some fashion, so there is no question about whether one is changing power output levels during a TT event day.

We have deleted the wording "Programmable fuel systems without control of engine timing". It is now simply "SAFC or VAFC". Quote

I pulled it from the latest TT classification form posted online. http://www.nasaproracing.com/rules/Time-Trial-Classification-form.pdf Quote

What if a car has boost adjustments features "built into the dashboard".... say... maybe a numbered wheel and a red button? Not sealable and within easy reach? Quote
soundguydave Posted August 26, 2009 Posted August 26, 2009 EVERYTHING can be sealed... a piece of racer's tape over the wheel initialled by the TT director would probably do the trick, either that, or build up a cardboard shield over the whole thing, and then tape that into place. Otherwise, it's just plain illegal. Quote
Trevor57 Posted August 26, 2009 Posted August 26, 2009 Nope. Some cars use the cruise control switches, and are UNDETECTABLE. There are also Bluetooth ecus. Quote
jason Posted August 26, 2009 Posted August 26, 2009 Now we see why NASCAR still uses carberators. Quote

What if a car has boost adjustments features "built into the dashboard".... say... maybe a numbered wheel and a red button? Not sealable and within easy reach? Seal the numbered wheel with tape so that it cannot be turned. If the red button is used to reset the ECU back to high octane mode when the knock sensor kicks the ECU to pull timing (Mopar factory ECU reflash safety feature), please make sure that the light works showing that the ECU is in high octane mode, and let your TT/PT Director know about it and inspect it prior to the event. Both Shawn Meze and I are very familiar with this particular modification, and if it is for a Mopar SRT4 ECU, it is not capable of other functions. We understand that Mopar added the feature to their reflash as a safety item (probably their lawyers required it since running the car with street gas with the reflash would blow up the motor), and made it a requirement that the button be pushed every time the motor is started to get out of limp (pump gas) mode. As well, if we Dyno the car, expect it to be Dyno'd at least once with the button not pushed, to ensure that the light switch has not been reversed. Quote
soundguydave Posted August 27, 2009 Posted August 27, 2009 Nope. Some cars use the cruise control switches, and are UNDETECTABLE. There are also Bluetooth ecus. I know what you're saying... Seal the cruise control switches, then, on all cars, and if there is a Bluetooth ECU, it will show up with a pretty simple RF scanner. That would work until somebody figures out another method. Then we police that one. Bottom line is that if somebody WANTS to cheat, they will, and all the rules do is make it harder. Same deal with revalved "OEM" dampers. The point I was trying to make is that if there is something that should be "sealed," there is a way to seal it. Quote
