problem with these overpowered cars is 

alot of them have had a big horsepower engine fitted with no other modes done to chassie brakes and so on 

had a few people come to me for conversions , but only wanted bigger engines no chassie or brake upgrades 

told them not interested and go away ( being polite )

WA DOT/POL is run by some very nanny thinking people, they have been on a campaign since the early 2000's to rid all cars older than 1990 from the road, and put a halt to all and any modifications(including factory option to model cars, ie V8 in 6cyl holden, turbo engine into n/a VL/jap car etc).

There was a big report commissioned into road safety and crash data ~4 years back which when viewed from their nanny head-in-arse position lead to current we-make-out-own-rules WA policies, and hoon laws etc, I have read several letters and been lectured too personally about crash safety of older cars and reasons why they don't want to allow HP in older cars, and there are some valid arguments against it, a little paranoid, but they are valid arguments, and denying they exist like a lot of pro modification people doesn't strengthen your argument.

Its also a pity at the same time engineering to improve performance and safety is flat out refused with no consideration because its too hard and no one wants to understand it.

 

 I've been modifying cars since the 80's, and I knew from the start(probably from driving farm hacks on dirt and doing stupid shit since I was old enough to reach the pedals myself..been real lucky!), that common sense is a must have, a man's gotta know his and his cars limitations, modifications can't be a death trap and you keep your fuccking head down when your doing/driving something that's not quiet legal !

 

It gives the departments way too much fuel for their own nanny argument with all these big hp cars in magazines and on social media which, have plates on them, are shown driven on the road.... and then talked about in the interview being "great and nice to drive on the street" <- which most of the time total bs, a big stall full manual auto with solid drive line mounts, kirky seats etc etc sucks balls to drive for any distance.

 

/end rant

 

TLDR: If you want to be a hoon and drive your race car on the street, time and place and Keep Your frOcking head down so you don't draw attention and ruin it for everyone.

Too many cheating it. If done right should be no issue.
To be fair alot more people now think about suspension and brakes when modifying, years past these were not a consideration

Agree with you oversteer, if your going to drive them on the road, try not draw attention

Like everyone is saying, there is people ruining it for everyone else

 

Especially this x power and x 1/4 mile "street" car ego war on social media. It is a track/event car with plates get over yourself

 

My car was trailered everywhere until i completed the engineering and modification permit process and it was rego'd the whole time

500hp is enough for me in an older street car. My HQ will easily get me in to trouble if I were to be a dick. Had plenty of big engine cars and reckon 500hp is pretty much enough for a streeter. After that you really lose too much drivability. Bit different with the more modern cars though but who cares about them LOL.

 

My two bobs worth.

I agree. An XY GT-HO had about 330hp. HT-HG GTS350 had 300hp. Both were 14s cars on skinny street tyres with manual transmissions and weighed about 1500kg. 400hp is probably enough on cars of this size and style of suspension. Drop back in size and weight to a Torana and 300-350hp is probably enough for a regularly street driven car. Personally in a bigger car I’d rather a big cube engine with less power and bulk torque, like a 350-400hp 427 with 600Nm of torque.

If the cars in question are talking it up in the magazines, running hard at the strip but driving like miss daisy on the street what’s the problem?

if they are ripping it up in the neighbourhood that’s a problem!

 

Is there a problem in WA with 1000hp cars doing burnouts and street racing?

Mine has 403rwhp with estimated 550ftlb flywheel torque. 

Definitely enough to totally [email protected]#k  you up if not concentrating but always wanted more at  the drags (though gearing wasnt ideal)

Makes a 1200kg car boogie

Big horsepower is fine if you use it in the right place, not in traffic or built up areas. Obviously the car first of all has to be made to be able to handle it, with strengthening, brakes, handling etc. Too many high horse cars out there set up for the strip that won't go around a corner.

You are just trying to justify your car Brett  :stirpot:
