Submission 1

Rule submissions for discussion

Junior Drag Bike

/JDB

 

Concept

This division is intended to cater for competitors between the ages of 8 years and 18 years, racing small replicas of drag bikes over a maximum of 1/8 mile. This is an introductory class intended to teach youngsters the fundamentals of motorcycle drag racing. An ET restriction of 7.9 applies to Senior, 8.9 seconds applies to Junior’s, & 12.9 seconds for Beginnerr’s. A cushion of 0.2 second (7.7 Senior ,8.70 Junior & 12.7 Beginner) will apply during qualifying only, but qualifying times under the 7.90 / 8.9 / 12.9 indexes are deemed to be worse than all times over the indexes, with the greatest amount under being deemed the worst.

Note: Any vehicle running under 7.7/ 8.70 / 12.70 during qualifying or eliminations will be disqualified from any further racing at that event. In the event of a breakout or dual-breakout, the lesser infraction will be declared the winner.

Note – Class requirements must be read in conjunction with the General Racing Regulations 2.0 and Bike Safety

Regulations 6.0.

NZDRA Junior Drag Bike Licence required. Letter of consent is required from parents / guardian and are also required to co-sign Entry indemnity form. Refer Racing Credentials Section 3.0.

Qualifying – Best non red reaction time.

Turn-around time: 15 minutes from last pairing.

Note: - Junior Drag Bikes must stage under their own power unaided by parents or disqualification will result. (Licensing runs accepted).

To the NZDRA board,I have been active in drag racing for over 15yrs 

More recently owning and driving an early Front engined dragster,I sold this to get my two children Jaxon 10 and Ellie 13 into junior dragsters.This class is great and meeting so many like minded parents who's children also share the passion  for racing.

This submission is NOT a rule change it is a WORDING  change.NZDRA's interpretation and that of the parents is different.As I understand it NZDRA misinterpretation has caused a few grumbles and outlaws all but a couple of  alcohol briggs motors.After consultation with alot of other junior dragster parents I/we believe this wording change will bring clarity to the curreny ruling and as tgis is a DYO class that still has E.T caps in place the safety will not be compromised for the drivers. I would like to submit the following WORDING changes 

Original wording .... ENGINE 

Junior: maximum of 125cc motorcycle engine,or Briggs &Stratton  engine ,or equivalent, Honda,Robin, Tecumseh  etc

As per NHRA & ANDRA rules.

Submission change

ENGINE

Junior: Maximum of 125cc MOTORCYCLE ORIGINATED MOTOR

which uses an internal gear box

OR Briggs and stratton or simular stationary style motor which uses a CVT/Torque converter style clutch (no gear box) of up to 500cc

ENGINE

Senior: maximum of 250cc motorcycle engine,or Briggs &Stratton  engine ,or equivalent, Honda,Robin, Tecumseh  etc

Submission 3

Rule submission, requested by Steve Acker, seconded by Rhys Jones ( smoo8@hotmail.com )

Junior Dragster Class

Under class requirements the class age restrictions  remain the same.

Junior (j/j) 8 to 11 years

Senior (s/j) 12 to 18 years

I would like to remove the current engine size rule

“Junior: maximum of 125 cc motorcycle engine, or Briggs & Stratton engine, or equivalent, Honda, Robin, Tecumseh,

etc, as per NHRA & ANDRA rules.

Senior: maximum of 250 cc motorcycle engine, or Briggs & Stratton engine, or equivalent Honda, Robin, Tecumseh, etc,

as per NHRA & ANDRA rules “

And replace it with a fastest ET rule as per ANDRA rules except with a change in ages to reflect current NZDRA age restrictions for the Junior (j/j) and Senior (s/j) classes and a change to current NZDRA ET times.

For drivers between the ages of 8 and 11 years inclusive, limited to ET no quicker then 8.50 and a top speed of no faster than 60MPH (96 kph) (1/8 mile)

For drivers between the ages of 12 and 18 years inclusive, limited to ET no quicker then 7.90 seconds and a top speed of no faster than 80mph (128 kph)

With the ET restriction it isn’t necessary to have top speed restrictions but have left these in the rule submission as a guide .

My reason for this rule submission is to make it slightly more affordable , for example if Tom starts to race at 13 then Toms sister Jane comes along and wants to race at 9 they can effectively race the same vehicle and just govern the engine to reflect proposed ET restrictions rather than having to change engine sizes as per current rule.


Submission 4

In my role as a NZDRA Tech Inspector, and a parent who has 2 junior dragsters, I have come across an issue regarding the engine size restrictions. This has been bought to light recently with a Junior Dragster I have personally inspected.

There are discrepancies between the NZDRA rules, and the IHRA NZ rules. There are also issues with the interpretation of these rules.

NZDRA rule book states:

Junior: maximum of 125 cc motorcycle engine, or Briggs & Stratton engine, or equivalent Honda, Robin, Tecumseh, etc, as per NHRA & ANDRA rules.

Senior: maximum of 250 cc motorcycle engine, or Briggs & Stratton engine, or equivalent Honda, Robin, Tecumseh, etc, as per NHRA & ANDRA rules.

IHRA NZ rule book states:

Beginner: Maximum of 125 cc engine or Stock 5HP (210cc) Briggs & Stratton engine or equivalent Honda, Robin, Tecumseh etc.

Advanced and Master: Maximum of 250 cc engine or Briggs & Stratton engine or equivalent Honda, Robin, Tecumseh etc. as per IHRA rules.

IHRA states:

..”one rear mounted, 5hp based, four cycle engine…. Accepted aftermarket engines Metro Racing flathead, McGee Racing flathead, Tecumesh flathead, Pure Power Racing flathead, LPW Racing Products flathead, JR Race Car flathead, Huddleston Performance flathead, R&S Machine flathead, Monster Racing flathead….” etc, etc.

NHRA states:    

All vehicles restricted to a maximum of one rear-mounted — based on a fivehorsepower,

single-cylinder, single-spark-plug, flathead-configured, four-cycle engine or factory-sealed Briggs & Stratton 206 crate engine — engine from a recognized OEM or NHRA-accepted aftermarket supplier.Accepted aftermarket engines: Metro Racing flathead, McGee Racing flathead, Tecumseh flathead, LPW Racing Products monster racing block, JR Race Car flathead, Pure Power Racing flathead, M-1 Machine racing block, SR71 Racing Block by Soltz Racing, Huddleston Performance Sniper, R&S

Machine Terminator, and Briggs & Stratton 206 factory-sealed engine

 

ANDRA states:

Any four stroke, single cylinder, sidevalve engine accepted by NHRA (US)…

The issues arise mainly from the wording from the NZDRA ruling. This states a “maximum of 125cc/250cc motorcycle engine, or Briggs & Stratton….” It depends entirely on the interpretation of the “or”. I have spoken to several NZDRA members, and their general interpretation is that the cc ruling applies to all engines.

This seems to be confirmed by the IHRA NZ ruling, which is essentially the same except for the exclusion of the wording “motorcycle engine”. Again it depends on the interpretation of the “or”. But having said that, the IHRA NZ ruling for J/JD then states “Maximum of 125 cc engine or Stock 5HP (210cc) Briggs..” which seems contradictory in itself.

Both NZ rule books state “as per IHRA/NHRA/ANDRA rules”. None of those rulebooks have ANY engine size limits at all. The engines are all single cylinder flathead type engines, and almost any modifications are acceptable. This makes both NZ rule books very open to interpretation, and therefore disputes.

I have researched most of the accepted US manufacturers of the engines, and not one of them produces an engine as small as 125cc, and almost none of the engines are under 340cc. The most common engines run around 400cc, with engines as large as 540cc produced.

This would mean, by (some) interpretation of our cc rating rules, that NONE of these engines are legal for use in NZ Junior dragster racing.

I feel that the rules should be rewritten as “maximum of 125/250cc motorcycle engine, or any Briggs based engine accepted by IHRA/NHRA/ANDRA.

All Junior Dragster racing overseas is governed solely by E.T. and our classes also have this restriction in place. I feel it is imperative to tidy up this ruling ASAP, before any other disputes arise.

Submission 6


 

Submission for Super Stock – Top Street

Current wording

X/TS       84kgs to 124kgs per litre normally aspirated to a minimum weight 1100kgs

Proposed new wording

X/TS       84kgs to 124kgs per litre normally aspirated

Or

X/TS      84kgs to 124kgs per litre normally aspirated to a minimum weight of 1000kgs

The first proposed wording is the preferred one as it brings this into line with IHRA rules which will encourage other racers into our class.

The second proposed wording is if the committee think that there must be a minimum weight and is to bring into line with Top Doorslammer minimum weight for a NOS vehicle.

I would like super gas reinstated in the rule book so that we can continue to build on the class and run it in the points series for next year and in the future.Regards Gerry Rose. Seconded John Shepherd

Reason For Proposed Rule Change:

As per the the last couple of seasons, if a competitor wished to attempt to reset a national record they had very limited opportunities to do so for the season.

The NZDRA National Points Score Series consisted of 4 events in the 2015/2016 season (not including the street car only event held at Tokoroa). Of these four meetings one was held at Masterton Motorplex at the beginning of the season, two at Taupo, and one at Motueka where Group one cars are restricted to 1/8 Mile racing.

As all seasoned drivers are aware Taupo is known for its elevated altitude which in general tends to mean most racers will end up running around 2 tenths of a second off their normally run times at other tracks, thus making it very difficult to reset a National Record.

Motueka running only 1/8 mile runs for Group One cars then means that they are not eligible to even attempt a National Record there.

And finally that leaves in my opinion only one realistic opportunity for the entire season to run a National Record worthy run, this being the Central Nationals run at Masterton Motorplex where a full ¼ mile track is available and safe and altitude isn’t a problem.

If we opened up the rule to allow National Records to be claimed at any NZDRA sanctioned event we would be giving ourselves at the very least 2 more opportunities per season for this to be attempted. This would be a far fairer outcome for all NZDRA license holders and would encourage more drivers to attend the other standard track competition events thus helping the sport grow as a whole.

Other drivers have approached me since this rule submission was denied last year and asked that I resubmit it again for this year. Please take into consideration the number of drivers who have signed theretheir name in support of this submission, this is what the drivers want.
