www.speedway.co.nz/asset/downloadasset?id=79f4572b-0b88-4287-b80e-1ebec9cca3a8Proposed technical changes are currently out for consultation and this one is back on the agenda. In the days when technical rule changes were made through conference, this one always sparked fierce debate but never went through. I don't have an opinion either way and would like to hear what more technically minded people think about this proposal.

Is adding create motor an option for superstocks and all those who wish to legally challenge the rule a new class gets created just for them and they can all race together. And it carrys all the history of super stocks but call them openstocks. I believe it's only a select few the oppose this change. They can race together as a national series.

In reference to the meaning of standard stock one may of thought that was the whole idea of the class . Now the proposal of a fuel injected engine takes away the meaning of the class beyond the imagination of those that are technical enough to develop quite a rapid engine ,even if the rules are set out ,.. There are some fast standard stocks racing just by tinkering in the back shed  |

Australian stock cars allow fuel injection, kepts the cost down from converting to carbs.

So I thought I would put my idea out there. |

There are still plenty of $250 falcon and Holden stock standard motors out there. Bring in fuel injection and those that are currently spending 20k on thier current motors will just spend 20k improving an efi motor if the rule is changed.

Curious if people bother to read the proposals before jumping on a bandwagon or pandering about unfounded ideas?
The cost factor isn't on the motors, its on the inlet & fuel management side - if you were building a car and had a complete long block with standard manifold, injectors, throttle body then you wouldn't need to go out and modify a manifold to then accept a carb (on a motor that was never carb'd) - It would be more reliable, smoother.
There's also no fuel in the inlet track of the manifolds so you wont get the flooding/fire risk when tipped on its side or after being poked in the wall. (and lower bonnet profile - so no carb/aircleaner waiting to be wiped off unlike a high-rise)
Key to remember the cars aren't going to get any faster as there's nothing fundamentally wrong with a well setup carb - they still have to run the same sized restrictor - any good Dyno operator will tell you that there's only so much air you can pump through a restrictor. - You only to have to look at the information from the previous trial where the dyno gains were minimal, and lap times stayed the same. Scott Frederikson among others ran it, and switched back to Carb to be able to run the NZ's at Woodford Glen from memory..
Where you will get a gain for the most part is the budget racers. You just have to look at Streetstocks who have been running EFI for awhile now, alot of Holden's & Falcon's are running stock EFI (admittedly the BA's have to use a aftermarket ECU from what I understand) on largely standard motors..
@ Driftwood, "Standard stocks" were the precursor to "Stockcars" - before Stockcar & Superstock separate grades. Largely road car based components in the stockcar/superstock chassis. Ie no quick change gearbox & diffs, wilwood brakes etc. Originally designed to keep costs down and more of a level playing field (and as a by product slower than a Superstock)

Thanks for the detailed analysis on what a standard stock was mrdamage I think there are some people on here that will learn from it.

then trick ECU, throttle body mods where will it end the search for speed

Already know of a driver who will be racing a fuel injected motor for the rest of the season, he says it will not give him more speed, but quicker throttle response to attack, or get out of trouble  . He ran fuel injected for the last 5 meetings of the season, the last being the king of the arena and it ran like a pig.

If passed id suggest something like this with 2 options for engine.
Option 1.
Engine built to current STOCKCAR rules
Option 2
Engine built to current STREETSTOCK rules
This way rules already exist.

Did the changes happen? Are all the two barrel carburettors with high rises now in the bin?

why would the hirise carbs go to the bin, FI is not going to give an HP advantage to a well set up carb. it should be safe though when a car is upside down

Fuel efficiency I guess. You don’t see many drift cars with carbs. One advantage for EFI would be when the car smacks the wall and stalls it won’t take so long to start. I guess one measure will be at the Nz tittle see how many in the top 10 are carb vs EFI |
