Great news about this class. Any ideas on what to call it. Superlite would have been spot on as it was between Super 1650 and Prolite but the Golf carts got that. How about "Supersport". just a bit of Super 1650 and the almost gone Sportsmans.

Any other ideas??

And if we leave it as class 10 then any imported Class 10 will have a race number already on it, and within spec. Easy times

Well done Shane and all involved.

G'day Guys,

I have been looking around at 2.5ltr engines to suit this class and this Nissan juke things keeps turning up with a 1.6 ltr turbo.
Is this the way the manufacturers are now going?
Would this fit in the new class?
would this give the old 4agze a home?
Any 1600 buggy with a $300 sc14 blower would have a home as well? ( theres about 1/2 a dozen for sale on gumtree at the moment.)
Given the specs on some of the 2ltr and 2.5 ltr N/A engines currently on the market I don't think atmospheric compensation will dominate.
If some of the numbers I have heard in relation to cost and hp for the v6 3.5 ltr Nissan these days are correct, ( cosworth heads ,ITBs,4 variable cams , motec m100 series the list goes on.
Forced induction in some form maybe the only method of maintaining some parity within the class that's somewhat affordable ( if I can use that word in regard to offroading)
From what I have seen prolite is a one engine class with the odd exception.

Would we end up with a extremely varied ultra competitive somewhat affordable class that puts to bed any amalgamation with super 1650.
How about that a win all around !!!

Thoughts anyone !

regards David

It couldn't be any bigger than 1.4lit David if using a turbo. Multiplication factor is 1.7 for forced induction. I believe turbo's should be allowed.

G'day Guys

Just to clarify my comments above regarding turbos.
There has been a second proposal put forward to increase the capacity of the new class to 2750 and to include turbos.
This is recorded in the minutes of the aorcom meeting I would put the link up if I knew how.

I think it is by far the best option so far.
Lots of options and variety.
something there for a lot of engines and buggies.
I think it also addresses some long lingering issues as well.


Thoughts

Regards David

Keep the turbos out of it, the simpler the better, and as for the 4agze why would you want to introduce a class to run an engine that was made in 1986? Class 10 in the USA is just about the most popular class, due to the fact that the engines are simple and can't be tampered with, we need to adapt this approach for Australia, a one make engine class is too hard but a 2.5 4cyl only class is very manageable and very cost effective. Why do you think prolite went N/A? Turbos are for pro cars.

Thanks Lamby for the comments I was wondering whether anyone was looking here.

I do not think the proposal is about the 4 agze but more any 2.5 ltr and engines similar to the mr16ddt.
Is the mr16ddt type of engine engine the way of the future we need to cater for this type of engine you are right we need to look to the future. Even v8 super cars will be just super cars in 2017. They will run turbos. We cannot leave our head in the sand here.
I often hear the comment about getting old cars out of sheds old cars old motors. I agree in looking to the future but if it captures a few older cars bonus.
Every super 1650 out there will have an "old" engine where does that leave them down the track. Is there a plan for super 1650 does it need one ?I have read a few comments requesting not to touch it and I totally agree but they are an old engine class. Personally I believe 1650 should have had a control gearbox and control suspension years ago but that opportunity is lost now. And before anyone gets on there bike I have owned and raced one since about 1991. Its sitting in the shed beside the new one.

I would love for there to be a control engine class but I do not think we have the numbers for this and then what engine and what specs would we go with. There are a number of ecotec options for class 10 and they are not overly cheap. I am sure there is a reason for this so maybe I can draw some one into the conversation as to why I have seen a few ecotec options.

I like the idea of a 4 cylinder 2.5 but from what I have seen there are not to many of them around . I believe we need a broad brush approach so maybe there is something for everyone. A V6 is a big motor for an older car and a 4 cylinder maybe a bit small for a new buggy. (especially if the 3mm wall 1 3/4 inch cage proposal gets up). This is a very complex issue but that said once the rules are made it would be difficult to change them.
I could rave on for days about the pros and cons of building a new buggy that you plan on having your daughter and sons race and maybe if we excite some more banter I will but from my point of view of currently building a new buggy the new proposal for a 2750 and turbo class looks real good.

Please ladies and gentlemen don't afraid to give me a switch up if you want, the more brainstorming and opinions the better

regards
David

keep it simple, why make it confusing and hard to keep in check by adding turbos?!! Heaps of up to 2.5ltr options as there is no need for the turbos. Thanks for making it an even more difficult job of trying to get this new class in which we already have heaps of support for.

Not many around? AORCOM received over 30 emails in support of this class proposal! With many currently owning cars that will fit this class allready.
The idea of bolting superchargers on to old super 1650 engines is crazy, adding forced induction to an engine that was never designed for it isn't an easy job at the best of times so trying to do it on a small budget will only end in tears.
The availability of a lot of the current 1650 engines is drying up so to add extra stress on engines that are becoming hard to find will only be a short term proposal, and as for the "get cars out of sheds" argument that keeps getting thrown around, cars are in a shed for a reason, either the owner no longer has the time or money to keep racing and wishes the good old days were back when you didn't need all the safety gear and a datsun/kombi setup was winning races, or they just simply don't have the budget or energy to go racing anymore.
Also using v8 supercars as a role model is not the greatest idea, just this week Volvo has announced its withdrawal from the series joining a long list of manufacturers that are exiting the category, as well as fans losing interest rapidly.
There are so many options available in N/A 2.5 engines from most manufacturers that we're going to be covered well into the future, with the majority of small engines being N/A.
There is allready a lot of discussion that the turbo/ 6l multiplication factor in pro class doesn't have parity so to introduce it to another class doesn't seem logical, there's only so much power a n/a 2.5 will make and keeping it simple will be for the greater benefit of the sport.

It seems to me that the push for 4 cylinder only is driven by the desire for people to be able to purchase an American class 10 and to be able to be successful without changing anything.
Limiting it to 4 cylinders reduces the engine choices with Honda , Toyota and Nissan all making 2.5 litre V6's , many of which are in the same family as their 3.5 litre versions making it easier for people to move down fro Pro-Lite. In my opinion if this class goes ahead it should be able to meet the needs of everyone who is considering this class not just those wanting to import a race ready Class 10.

Also turbo and N/A motors don't belong in the same class.

So can Rotaries play in this new class? Or is it exclusive USA Class 10 ECOTEC cars only?
