I woke up this morning thinking that I've never seen a car race where Power to Weight ratio is a class.

There's power band, engine size, NA, Turbo, Rear wheel, Front wheel classes etc... but I never seen a race where cars are put into classes where Power to Weight is the same or similar. It would open up the track to a much greater variety of cars.

Does it exist? If not, is there a reason?

I have no idea why I woke up with this in my head.

Power to weight has very little to do with circuit work.

Think Bathurst.

2 Cars both have the same power to weight, 1 has 200hp 1 has 600hp, which do you think will get around to mountain faster?

Curious...what race class has limits on where in the RPM range you can make power? (power band)

OK in that particular track, I would think Torque would come into play, fair call. (Forget that Power Band example.)

But say the track was flat? I would think it would be a close race wouldnt it? Actually when I think about it, I guess it would be a dis-advantage for the 200hp car on the straight. But say use the track at Wakefield. When I last went, the Hondas were eating up the bigger powered cars. I guess it depends on the track aye.

I guess why I was thinking of this was I was watching a Mini-Cup challenge on the weekend that I taped. All cars, identical, only thing that separates the winners and losers are the skill of the driver. But it got boring after a bit watching the same cars drive passed over and over. Would be nice to see a race where different types of cars compete together in a fair way.

I know the GT races are kinda like these but they're all Super Cars. Would like to see something more like the World Time Attack Challenege they had here last year.

What you are thinking of is IPRA (improved production) turbo cars need to run inlet air restrictors, there are minimum weights for different cars etc.

The only real bullets in a straight line are the 6L V8 Commodores, but then they are massivly under tyred so are slow through the corners and have to get on the brakes earlier etc

Production sports cars used to run power/weight classes, ie you could choose whatever power and weight you wanted but you would be competing for points against other cars with the same power/weight.

The issue of course is weight is easy to measure and power is not. they used to take a dyno to some rounds and check some cars but it was just too hard to stay on top of. And too easy to fake lower power for a dyno run (eg boost controller or 2 maps on computer).

Tyres are really the best limiting factor IMHO. Keep everyone on the same, cheap, average tyres and lots of other things even out....

control tyres are good - but also racing in a one make class is good cause then while some people have big budgets, others dont and is quite competitive.

Duncan you raced in the Daewoo series hey? so pretty much control everything! comes down to skill!

If I were to race in Prod Sports (which my car is built for) Im up against other 2F cars such as lotus's, rx7's, porka's etc which will suck balls.while in the mx5 class, its good as everyone has a different budget and is fun!

but I still come last. haha

lol you beat a lotus chris, i remember it well :D

building a car to a class is a good idea (I did it :P) but it is not simple, easy or rewarding. It is limiting and frustrating. My GTR must be about the slowest one in the country!

But from when I first decided to build my own car, I knew I could not outspend the competition, so I went looking for tight rules where budget did not automatically determine who wins.

One make racing was excellent, but because it is close it is full of cheats. The Daewoo series was controlled one make so we couldn't even have the cars to fiddle with them - even so there was 10% power difference between the slowest and fastest of the 20 cars. 10% is a mile. The one time I got the quickest car (wakefield 500), Tom, Mark and I were leading by literally 1 lap when the power failed :(

So basically....there is no such thing as a level field, and no category where you don't need a reasonable budget to win.

easy...supersprinting :D where are you based?

NICE! Thanks man. I never knew about this... I googled this: http://www.supersprints.com.au/

Is this what you're talking about?

What do you win? Is it just for glory?

Based in Sydney.

supersprints are good fun and good entry level.

to give you a run down...

A skyline is to go into class SVD.

Its against the clock - but you are in a class.

you dont race for position on track as its not a race,well, more a race against clock and quickest lap wins.

in SVD class, you'll be up against GTR's, EVO's, highly modified commodores and falcons etc - most will be street registered. in fact I think they have to be street registered to be in SVD

My MX5 is 2B which is 1600-200cc and street rego'd with some modifications

There is the CAMS state supersprint series, and there is also the interclub one. I have done a a couple rounds of the CAMS one but 2009 I did the interclub one with southern sporting car club. 2011 I'll hopefulyl do 4 out of the 6 rounds.

I was just reading this: http://www.supersprints.com.au/rules-and-regulations/2011/2011%20Vehicle%20Regs.pdf

There is no SVD? Just an SV and I dont think I'd be in that.

I'd probably be in Type 2 class with my 350GT with only an exhaust, braided brake lines & slotted roters as mods.

There is no entry fee information on the website but I assume that it will be in something like a normal club day out like $200-$300 depending on the track??

Whats minimum spend on entry\rego fees in a SuperSprint Championship series? (Excluding car mods\repairs that is...)

nah your car is SVD. Not type 2.

there are different SV type classes but skylines fall under SVD unless you have an r32 or r35 aussie delivered.

the rules are weird.

entry is anywhere from 180 - 220 and you'll need to hire a timer beacon for 10-20 bucks

no rego fee's for them.

if you want more a relaxed series, the southern sporting car club has 4 at wakie and 2 at EC and isnt as full on as the CAMS state round.

google sscc

cheers!

yep!!

some SVD racers do 1.40's at EC and 1.04's at wakie...

however, go there for the fun and try and beat your PB each time!!

if you are out there for fun (most people are!) who cares what lap times, you are out there enjoying your toy! just make realistic lap time goals and aim for them each time!

if you then get serious and bug has bitten, sell and then buy something that maybe comptetive in another class (like me haha)

    • Greg speaks wisdom. These dirty old Datsuns are only value when they are cheap. When they are not cheap, there is no value. Sounds contradictory, but it's true. We are now 20 years past the hey day of modifying cheap 90s JDM cars for small amounts of money. This is a different world. If you are rich and can afford not to care about what is effectively wasting money on an old Datto shitter, then I have no reason to argue against it. But if you are wanting to experience what we all experienced back in 2005 (and I bought my car last century!) then there is no way to do it.
    • Short answer: No. Medium answer: No, because you still need to conjure the things out of thin air to bolt them to a NA to make it a NA+T. Long Answer: No - The things you need to conjure - meaning a turbo, intercooling, manifolds, exhaust, intake/manifold/piping, clutch, injectors, fuel pump, AFM (?), ECU + Wiring (woo, N/A loom fun) have to come from somewhere. You could have many scavenged these things from an OEM car that someone had upgraded from and use some of these. This will be cost prohibitive now, especially so in the USA. You'd probably pay the same for newer, upgraded components that are better than old OEM stuff from 25-30 years ago. None of these big ticket items are re-usable for the N/A car. Why not buy new and upgrade while you're there? The only real consideration is turbo and fuel sizing and determining whether you want to stay within the bounds of the OEM engine or get into rebuild territory. These limits ARE lower with a N/A motor and especially N/A gearbox at the starting point. And if you're gonna upgrade those then you may as well consider having them built to begin with. Because everyone here knows you're never far from that next engine rebuild once you start making the power you want... The cars you see on the internet and SAU etc have been built over decades. If you're really clued in... you would sell your US car to somebody for what you paid for it. You would then scour AU JDM pages or SAU and buy a car like Dose's on this forum with your powerful American Dollar. This will save you so much money in the long term. Importing it could be tricky. Or it might not because USA. I have long said the only reason 90's Japanese stuff took off was because a) Japanese people had Japanese cars so that is what they used b) Australians could import these cars to Australia with very minimal changes and use them on the road here c) Neither country had well-priced access to US or EU Sports Cars. I don't believe the JDM scene would have taken off in Australia at all if we had EU priced EU BMW M offerings, or more especially the AUS V8 Scene would never have existed if we had the multitude of US cars like Camaros, Mustangs, Corvettes at the prices you folks do. After all - Do the math. I would say put a V8 in your R34 and that's the smart way forward. It is. I did it. I know this from my own experience. But at that point there's no reason to simply not buy a C5 or C6? It would be simpler and easier and cheaper and bette-
    • Reading all this... hurts lol. I have an ENR34 5MT and I paid an inflated USA price for the car alone, had to do tons of preventative maintenance past that, and so I'm over $30K USD into the car already and haven't even touched power.  I wanted to +t it. Not even trying to make GTR numbers, I'd be happy with 250hp.  Can I get away with paying much less to make that happen?
    • Damn you’ve done well, definitely snapping necks.
    • Great weekend and event. Open fire at the caravan park, perfect weather all day and a great feed and a couple of drinks at at awesome country pub.
