motorsport rules turbo's

[dbr]

Currently, the Victorian rules put any vehicle with a turbo in with the racing cars (open or restricted open if under 120rwkW),
From the information on this site, NSW appears to have a "street turbo" class, which may encourage some more road going turbo cars onto the race track.
I have not been able to establish the rules for turbo cars in other classes. Could someone from each state tell me the current racing classifications for turbo vehicles in their respective state's MX5 club championship?

Vehicle regulations for MX-5 Club of NSW track days are based on Type 2 in the NSW Supersprint Championship. Details are here (refer pages 14-20). All MX-5s fall into Class 2C for engine capacities of 2001-4000cc (including the x1.7 multiplier for forced induction). No modifications to the EMS or induction system are permitted on FI cars, although some internal mods are allowed. Turbo MX-5s are also eligible for Type SV if they have modifications that are not permitted in Type 2 (maybe they can go into Type 3 or Type 4 too???). There's a lot of detail in there which I've never bothered unravelling as it has no direct impact on me in Type 1.

David,

The Vic club rules only put turbos over 120rwkw in with the 'racing cars'.
If less than 120rwkw then you can run in Restricted Open (which could/should be renamed Super Modified rather than Restricted Open, as it is essentially Modified rules with extra 30rwkw allowance and rear wings.)

Restricted Open was designed to give a class for std ish SEs, SPs to compete, without having to compete against the race oriented vehicles, and so typical entrants here are road going low blow turbos, modded NCs, and tweaked Modified cars that sneak over the 90kw power limit.

There certainly hasn't been in the past, nor will there be in the future, any race monsters in this class. (They must still run carpets and passenger seats same as the lower classes for example)
You'll find that the current lap records in Res are all close to or even slower than the Modified records, and your car would be extremely competitive in Restricted Open as is..

Thankyou gentlemen.
My enquiry was motivated by an attemp to get more of the turbochanrged road cars into the Victorian motor sport events. One aproach is to look at the different rules currently in use and then ask the contributers to this forum what, if anything in the rules is discouraging them from entering. For example, is the 120rwkW limit to low? However, I do understand that while motorsport is a good legal way to enjoy fast cars, not everybody wants to participate.
A lot of effort has gone into the varrious rules and I hope I have not offended the people that have put in all that work.

hi David,

(no offence taken by me... )

Talking to members at some of the club functions I've been too, there seems to be a common theme (and sadly not necessarily a correct one) of why they dont want to participate. That being they dont want to wreck/thrash their car by taking it on a track. Seems many have the assumption that driving their car on a track is ruining it.

Yet we have a lot of basically std cars who turn up, run around all day and then drive home again with nothing more than some extra wear and tear on tyres and brake pads to show for a day of fun at the track.

I think also that some would like to take their car around a track, without an interest in pushing to the last degree, but dont feel comfortable driving at 8/10ths when every one else on the track is driving at 10/10ths..
The driving training days certainly helped some to overcome this, though maybe we should look into the possibility od running a 80% day where people could run on the track at their own pace without feeling like a mobile chicane this could tempt more people to try it..

My 2c.

This is the problem with the world. Everyone thinks they need turbo's and more power to go fast.

There are ways of generating more speed or faster laptimes that DON'T require turbo's, built motors, or expensive engineering bills.
The current Vic rules around Classes are not perfect, and if you read the rules closely, you'll note Restricted Open class is a waste of time. You're basically either in Modified or Open.

There is plenty of provision in the rules if you want to add power, but there is hardly anything to accommodate modifications that add speed in other forms. And unfortunately, if a modification isn't explicitly permitted, then you cannot implement it.

Allowing aero would allow so much needed development to the mx5 community.

There definitely needs to be more autocross/gymkhana type events for regular cars. The ozgymkhana kikuchi and I just attended was fielded by full on rally/ track cars that got trailered to the track.

Everybody wants a class that fits there car exactly. But I do think that the classes are all good exept res open. I can understand the rules are there for street se/sp cars and that's good.( However there isn't many competing that I know of) But it leaves a big gap for other cars that want to fit a couple of mods like adding lightness and aero without going to the trouble of seeking power for cost and reliability reasons. And Brendan knows about world problems, or at least has some basic comprehension. I think....

I'm not in love with the NSW club rules but as I've had pointed out to me, if you're taking it seriously, go do something more serious than club racing.

[lightyear]

It is not about taking it serious. The way i see it, the club motorsport is to keep it interesting by making some kind of competition out of a non competitive event in having a championship and class to run in. If it wasn't for that you would just show up to any old event during the year, and not an mx5 event in particular. I do other track days, as well as state and aus supersprint. But there are others that only really do the mx5 track days, because there are enough events in the year to keep most people happy, and you get to make new friends and catch up with old ones.

Racing is a good option if you can afford it.

[MrsB]

I think Lightyear has hit the nail on the head here!! You cannot have a class which will fit everyones car. If you raise the kw limit in restricted open then you disadvantage those who are at the current 120kw limit. Its never going to be perfect for everyone. At any level of motorsport you must comply within a structured set of classes and rules and the onus is on you to find the class which you want to compete in and prepare your car accordingly. Im not saying there is no room for improvement or refinement of the rules but the classes are designed to deliver a championship where everyone can have FUN safely which is the key objective of any club level motorsport and where the emphasis should be placed.

I agree we should not change the rules and discourage existing competitors. We have stability classes to prevent this.
However, if we don't explore possible alternatives, we may be discoraging potential new participants. If we had enough people saying they would participate, or participate more if certain rules where different, then we could create a new class. If appropiate the classes could be amalgamated later, after the stability clause was satisfied.
Based on the responses in this forum so far, there is insuficient interest for a change.

I'd say the opposite actually. The Vic rules are always a work in progress. The Motorsport group reviews and amends them at the start of each season based around suggestions and consultation from all the members.
