Question: My racing buddies told me that I will need to add a new front driveshaft tube to my Top Sportsman car.  Is this only in Top Sportsman or all classes?

 Driveshaft Denny

Answer: Your buddies are correct.  New for 2012 Advanced ET, Top Sportsman and some of the higher Competition Eliminator classes now require the driveshaft tube.  Driveshaft must be covered by 360-degree tube, covering the front u-joint and extending rearward a minimum of 12 inches.  Minimum thickness of tube is .050-inch chromoly or titanium tuing.  Driveshaft tube must utilize a minimum of four attachment points to the chassis, either bolted with minimum 5/16 SAE bolts or welded or -inch push/pull pins.

Question: I was watching the NHRA Full Throttle Drag Racing Series from Las Vegas and during Pro Stock Motorcycle qualifying one of the riders had problems and went down on the pavement just before the finish line.  What rider’s safety gear must be worn to help protect them during a 180 mph slide?

 Motorcycle Mack

Answer: The 2001 NHRA Rulebook states “Full all-leather or SFI 40.1/2 suit mandatory on motorcycles running 120 mph or faster.  Two-piece suits must be joined together with zipper at the waist.  SFI 40.1/1 or 40.1/2 suit or leather jacket, leather boots/shoes above ankle, and leather gloves are mandatory on ALL motorcycles.  Gloves must be Kevlar-lined or equipped with slide buttons

Question: I have run as fast as 190 mph in my Top Sportsman car.  Is it true that in 2012 I will need to wear a head & neck device?

 Head & Neck Harry

Answer: In the 2011 NHRA Rulebook on page 6, section 6B, Top Sportsman, NECK COLLAR/HEAD AND NECK RESTRAINT DEVICE/SYSTEM the second paragraph reads “Beginning Jan. 1, 2012, all drivers in this class will be required to wear a head and neck restraint device/system meeting SFI Spec 38.1.”  A head & neck restraint device can be used with, or without, a neck collar; when a neck collar is not used, an SFI 3.3 head sock or SFI Spec 3.3 skirted helmet is required. This would also apply to all Top Dragsters and any Advanced ET vehicle running 7.49 and quicker in 2012.

Question: I see that they make a swing-away steering column.  Would I be able to put a removable steering wheel on the swing-away steering shaft?

 Swing Out Sally

Answer: Yes you can.  In the 2011 NHRA Rulebook, section 20, page 15, 3.3 Steering, the last sentence states “NHRA-accepted swing-away steering column permitted with removable steering wheel.”

Question:  I’m going to add a fire extinguisher in my 1971 Pinto Pro ET race car.  What rules do I need to follow?

 Pinto Pete

Answer: A fire extinguisher in any race vehicle that is not required by rules to have an onboard fire system is a great idea.  A small fire on the return road can get out of control in a hurry.  In the 2011 NHRA Rulebook Section 20, page 35 talks about fire extinguishers.  It is recommended that each contestant have a loaded, serviceable fire extinguisher in their race car, available for immediate use.  Dry chemical or CO2-type, 2 -pound minimum size recommended.  Must be mounted in a secure manner; use of flip-open-type clamps prohibited.  Flip-open-type metal clamps with locking hairpin is acceptable

Question: We are preparing a dragster for Super Comp in early 2012.  The question we have is, our transmission case was SFI 4.1 certified and the tag punched out July 2006.  The case is 5 years old and needs to be re-certified, are we permitted to run a SFI 4.1 shield over the case?

Transmission Tony

Answer:  You would be able to add an SFI 4.1 transmission shield over your expired aftermarket case and it would be legal.  The other thing to remember is that the aftermarket case was also SFI 30.1 flexplate shield certified and you would need to now add a SFI 30.1 flexplate shield.

Question: I’m getting ready to go to the NHRA Summit Racing Series ET Finals and my NHRA ET number will expire at the end of August.  Should I wait until I go to Indy on September 15 and renew my NHRA number there?

 Expired Number Eddie

Answer: I’m glad you looked at your NHRA number/license card before it expired.  I hope that your local NHRA Member Track SFI Tech Inspector would have told you that your NHRA number was going to expire this month.  You should mail in an NHRA number/license so that it is in the NHRA Division 3 office before September 9, 2011.  Starting Monday, September 12 all other NHRA number/licenses new or renewal for the NHRA Summit Racing Series ET Finals must be taken to the paddock area building at Lucas Oil Raceway at Indianapolis starting at noon, Thursday September 15 for processing, there will be an extra $10 service fee when done at the event.

Question: I’m an NHRA SFI Tech Inspector and we see a few of the NHRA Lucas Oil Drag Racing Series class cars along with some Pro Stock Bikes and Cars come and run our Test & Tune nights.  I deal mostly with E. T. Bracket cars and my question is what classes require oil-containment devices?

 SFI Tech Tony

Answer:  The following NHRA classes require an NHRA-Accepted oil containment device or belly pan:
Advanced E. T., Super Street 135 mph or more, Super Gas, Super Comp, Top Dragster, Top Sportsman, Competition Eliminator, Pro Stock Motorcycle and Pro Stock.

Top Alcohol Funny Car and Top Alcohol Dragster require SFI Spec 7.1 lower-engine-ballistic/restraint device and engine oil-retention pan.

Question: Do I need to replace the seat belts in my Son’s Jr Dragster?  They have a manufacture date on the belts of July 2009.

 Seat Belt Stu

Answer:  Yes, your seat belt expiration date was July 31, 2011.  On page 45 of the 2011 NHRA Jr Dragster Rulebook in the DRIVER RESTRAINT SYSTEM paragraph it states “Five-point, 1 -inch-wide driver restraint system mandatory.  Driver restraint system must meet SFI Spec 16.1 and be updated at two-year intervals from date of manufacture.”  As a reminder this also includes the crotch strap.

Question: I’m in the process of building a Top Dragster for 2012 and wanted to know if there are any ignition systems that are not legal”

 Sparky

Answer:  There are two ignition systems that are not legal.  In the 2011 NHRA Rulebook in the General Regulations section 20, page 33, ignition, fourth paragraph it states “The use of any programmable multi-point rev limiter and/or rate-of-acceleration rpm limiter, either by themselves (e.g., MSD 7561) or integrated into the ignition system (e.g., MSD 7531), are prohibited in NHRA competition.”

Question:  Do I need a diaper on my Advanced ET Dragster that I’m finishing up?  I think it should run 7.20 in the -mile at my local track.

 Diaper Don

Answer:  In the 2011 NHRA Rulebook on page 10 of the Advanced ET section the top paragraph, Oil-Retention Device it states: “All vehicles running 7.49 or quicker must utilize an NHRA-accepted lower engine oil-containment device; may use a belly pan in lieu of a device attached to the engine.”  This also would apply to any Advanced ET vehicle that runs 4.49 - 3.66 in the 1/8-mile

Question: I just wanted to pass along a reminder on the new roll-cage padding rule that went into effect as of June 1, 2011.

Roll Cage Ritchie

Answer:  We have seen a number of cars that do not meet the new roll-cage padding rule that went into effect June 1.  Let’s see if we can get racers into compliance with this rule.  In the 2011 NHRA Rulebook on page 5 of the E.T. Section 4A and in the General Regulations Section 20, page 20 it states “ Beginning June 1, 2011, roll-cage padding meeting SFI Spec 45.1 mandatory on any vehicle running 9.99 (6.39 1/8-mile) and quicker.  Padding must be used anywhere driver’s helmet may come in contact with roll-cage components.”

Question: I heard that in 2012 I will need an SFI head and neck restraint for my Super Pro Dragster that runs 7.20 in the 1/4-mile.  Is this true?

 Head & Neck Harold

Answer:  You heard correctly.  In the 2011 NHRA Rulebook Advanced ET, Section 4C, page 12; Top Sportsman, Section 6A, page 6; and Top Dragster, Section 6B, page 9 it all reads the same.“Beginning Jan. 1, 2012, all drivers in this class will be required to wear a head and neck restraint device/system meeting SFI Spec 38.1.”

(Posted 06/14/2011)


Question: Have the Jr Dragster rules changed on fire pants and towing flags?

 Jr Daddy Denny

Answer:  No the rules have not changed.  As a matter of fact at the past couple of NHRA Division 3 races that we have ran Jr Dragsters, the Division 3 Safety Crew had to warn Jr Dragster to wear their SFI 3.2A/1 fire pants (yes even though it was hot) and display their fluorescent towing flag anytime the Jr Dragster is towed.

(Posted 06/07/2011)


Question: I hear that there is a new roll-cage padding rule that goes into effect in the near future?

 Roll Cage Rodney

Answer:  Glad you asked that question.  A new roll-cage padding rule goes into effect tomorrow.  In the 2011 NHRA Rulebook on page 5 of the E.T. Section 4A and in the General Regulations Section 20, page 20 it states “ Beginning June 1, 2011, roll-cage padding meeting SFI Spec 45.1 mandatory on any vehicle running 9.99 (6.39 1/8-mile) and quicker.  Padding must be used anywhere driver’s helmet may come in contact with roll-cage components.”

Question: I’m having trouble fitting my SFI 30.1 flexplate shield to my dragster.  Can I trim the metal to make it fit my car?

Flexplate Floyd

Answer:  No you are not allowed to modify an SFI product.  On page 3 of the General Regulations the second paragraph it states “Under no circumstances may any certified product be modified, altered, or in any way vary from the “as manufactured” condition.

Question: I’m finishing my Top Dragster and when I take it out it should run 7.0 @ 190 mph.  My racing buddies said I’m good with a single parachute and without a head & neck restraint for now.  When would dual chutes and a head & neck restraint be required?

Top Dragster Denny

Answer:  When looking at the 2011 NHRA Rulebook the Top Dragster class builds off of the Top Sportsman class.  T/D rules on parachute are silent so looking at the T/S parachute rules on page 4 if running 200 mph dual parachutes are required.  In T/D on page 9 an SFI 38.1 head and neck restraint is required if running 200 mph or faster.  Both T/S & T/D will require an SFI 38.1 head & neck restraint for all competitors starting 1/1/2012.

Question: I have a Super Pro Dragster that I recently purchased and I'm getting ready to race at my local NHRA track.  Looking at the wiring on this dragster it has an ignition wire hooked to the delay box.  There is not a tack in the car so I would assume that he used the delay box like a tach.  I didn't think this was legal?

Delay Box Dan

Answer:  You are correct.  In the 2011 NHRA rulebook, Section 4A, Super Pro, Page 7, ignition, it states "No other wiring shall be connected directly or indirectly between any other part of the ignition system and the delay box/device.  All wiring associated with the ignition system must be full visible, labeled and traceable".

Question: My Super Pro Car runs 9.50 @ 144 mph in the 1/4 mile and my local NHRA Tech Inspector said I would need to have a parachute on my car before I come back and run again.  He said if you run quicker than 9.99 you need a parachute.  Is that correct?

Parachute Pete

Answer:  Looking in the 2011 NHRA Rulebook in Section 4A, Super Pro, page 4, Parachute it states "Mandatory on any car that runs 150 mph or faster".  You need to contact the track in question and ask if their rules are written above and beyond the 2011 NHRA Rulebook to require a parachute at 9.99 or quicker even if slower than 150 mph.  If written and posted that way then you would need to follow the track rules.

Question: For 2011 I'm planning on my Pro ET car to run low 10's in the 1/4 mile and I will now need an SFI 4.1 trans shield.  I bought one a year ago used from a swap meet and my buddies are saying it wasn't legal without the lower pan straps.  What do I need to do to make it legal?

Lower Strap Lukey

Answer:  In the 2011 NHRA Rulebook, General Regulation section 20, page 14, 2:14, Automatic at the end of the 2nd paragraph it states "All non-blanket-type shields must incorporate two (or one, per manufacture's instructions) 3/4 x 1/8-inch straps that bolt to the shield on each side and pass under the transmission pan, or transmission pan must be labeled as meeting SFI Spec 4.1".

Question: I would like to take my Street Legal 2010 Ford Mustang convertible to my local NHRA track, but I do not see any Street Legal rules in the 2011 NHRA Rulebook.  Is there an NHRA Street Legal Rules Supplement that I can get?

Mustang Mikey

Answer:  If you look in a 2011 NHRA Rulebook on page XiV near the front you will see under the Street Legal page that Requirements and specifications for Street Legal are the same as those for the Summit Racing Series.  This means you must follow NHRA E.T. Handicap Racing rules.  Just as a note if your Mustang convertible runs faster than 13.50 in the 1/4 mile or 8.25 in the 1/8 mile a roll bar is required.

Question:  I heard that in 2011 there was an NHRA rule change pertaining to a laptop in the drivers compartment?

Laptop Larry

Answer:  You are correct.  There was a 2011 NHRA Rule Amendment as of December 6, 2010 on www.nhra.com   The 2011 Rule Amendment is in section 20, page 34, Support Group: 9, second paragraph.  It should read: During NHRA competition, a portable computer (e.g., laptop, PDA, Palm Pilot, programmer, etc.) must be securely mounted when located in driver’s compartment at any point beyond the staging area ready line.  All functions or values must be pre-set prior to this point.

Question:  What kind of safety rules do I need to follow with my nitrous bottle?

Nitrous Nettie

Answer:  See the following nitrous bottle safety article written by Mike Thermos at Nitrous Supply.  Also be aware that a nitrous bottle in the driver's compartment must have a relief valve and vented outside the drivers compartment.  Commercially available, thermostatically controlled, blanket-type warmer accepted

Nitrous has been used in our industry for more than 30yrs.  During that time, there have been plenty of magazine articles on how to use it, types of kits available, new products, dyno tested results, etc.  But the one thing that hasn't been discussed as often is nitrous safety.  So here are some tips on the safety issues involving Nitrous Oxide.

Lets start with the "aluminum" nitrous bottle included in the most of the kits you see on the market today.  There are several sizes and capacity aluminum bottles available.  Bottles are rated by how much nitrous they hold in terms of weight-generally in size ranging from 10 ounce to 50 pound capacity bottles.  The most common capacity (sometimes referred to as "size") bottle is 10 pounds.  So lets start here.  On the label you see on the face of the nitrous bottle is the "TARE" weight, which designates the empty weight of the bottle and valve without the nitrous oxide.  The weight of a bottle valve assembly can also vary up to and extra pound, depending on the manufacturer.  You will also see that the label will show the total weight of the bottle when full (filled to rated capacity).  This is very important, in that overfilling a bottle, although possible, can have extremely bad consequence.  A bottle is designed to be filled to 68 percent of its capacity and must have an "air bubble" of 32 percent to allow for expansion of the nitrous when it gets warm.

Speaking of temperature, when nitrous is discharged out of the bottle, it will be at minus 127 degrees and will freeze burn you almost immediately.  Care should be taken to wear gloves and goggles whenever filling a nitrous bottle.  Never put an open flame on the bottle to bring up the pressure.  Doing so will begin to "anneal" the aluminum bottle, altering the microstructure of the material and causing changes in properties such as strength, hardness and ductility,  If the integrity of the bottle is compromised by using an open flame, it is very possible to blow-up the bottle.

Question:  I’m having trouble deciphering what the punched out holes mean on my NHRA chassis tag.  The car that I purchased is a 1969 Nova that has a roll cage like you see in the NHRA Rulebook and it also has a funny car cage installed.  The blue/silver NHRA chassis tag is punched out 8.50 & Slower and at the bottom N/A.  Along the left side punched out 09 and along the top 7.  What does it all mean?

Chassis Tag Chuck

Answer:  Chassis Tag Chuck, The punched out dates along the left side and the top show that your car passed NHRA inspection in the 7th month (July) of 2009 and would expire in three years on July 31 2012.  The punch out of 8.50 & Slower and the N/A shows that it meets NHRA full-bodied spec that you see in the NHRA Rulebook.  The Funny car cage by itself doesn't let your car run under 8.50 in the 1/4 mile.  The SFI 25.4 or 25.5 spec for ET of 8.49 down to 7.50 does require a Funny car cage and numerous other chassis items before you can upgrade to either of those SFI specs.

Question: At last Friday’s test & tune my Super Street Turbocharged Mustang ran 10.20 at 140 mph and I was not allowed to make any more runs unless I ran 135 mph or slower. I thought if I ran 10.00 or slower in the 1/4-mile then mph was not a factor?

140 Gordy

Answer: 140 Gordy, in the 2011 NHRA Rulebook in Section 7 Super Street, page 1, Designation, third paragraph, it states “Any vehicle running faster than 135 mph must meet minimum requirements for 9.99-second vehicles.” This means if you run quicker than 135 mph you must meet the requirements of NHRA chassis inspection, if automatic transmission a SFI 4.1 transmission shield, 30.1 flex plate shield & 29.1 flex plate. Also, NHRA license, Snell or SFI full-face helmet, SFI 3.2A/5 jacket and pants, SFI 3.3/1 gloves & neck collar. The same rules would apply if running E.T. bracket racing.

Question: I heard that in 2011 I will need an engine diaper on my 1969 Super Pro Camaro to run at my local NHRA Track.

Diaper Dan

Answer: Diaper Dan, I’m getting a number of phone calls on the requirements of an oil-retention device for ET Bracket Racing. In the 2011 NHRA Rulebook if you are running in ET Bracket Racing you are not required to have an oil-retention device as long as you are not running quicker than 7.50 in the 1/4-mile or 4.50 in the 1/8-mile. You need to check with your local NHRA Track to see if their rules require any type of oil-retention device, there are a number of tracks that do require oil-containment if running quicker than 9.99 in the 1/4-mile or 6.40 in the 1/8-mile before you can run. So again, make sure you check with your local track. DRE is a proud sponsor of Coles County Dragway is giving a racers discount on diapers. For more information contact Dennis Ridgeway at 217-454-5289.

Question: One of my racing buddies said he heard that I would need to replace my roll-cage padding before I race in 2011. Is this correct?

Answer: In the 2011 NHRA Rulebook on page 5 of section 4A, E.T. Handicap Racing, Roll-Cage Padding it states “Beginning June 1, 2011, roll-cage padding meeting SFI Spec 45.1 mandatory on any vehicle running 9.99 (*6.39) and quicker. Padding must be used anywhere driver’s helmet may come in contact with roll-cage components.” This not only applies to E.T. Handicap Racing but to any class or vehicle that runs 9.99 (*6.39) or quicker. Looking at a racing parts catalog you can purchase a 3-foot piece of SFI Spec 45.1 Roll-Cage Padding for under $20.
