What would it take to get a Commodore to 300+ Km/h?

[whitels1ss]

In 1990, Opel did a Lotus turbo version of the Omega A which reached 283 km/h, pissing off BMW and Mercedes. The Omega A was a fleet/family car, pretty much like a VP Commodore.
I presume Lotus did a bit of work on the aero, as well as boosting crap out of the engines. I doubt the humble Omega was designed to go that fast. Most of them had pissy little engines.
The Omega got killed off before they could put a V8 in them. The ones sold in Brazil got a 4 litre engine, wouldn't have been faster than a Dunnydore.

Well, that is what I call thread dredging, we don't need to ask you to

This thread is over 9 years old

Welcome to the forum buddy

In the US its 200mph in the mile which is the aim for many and seems to be around 1000hp needed in current model Camaros. All it needs in a VF is the same just grunt to spare and wind it out in 6th you may need a few aero aids in the front to help down force.

Better than starting a new thread haha

You should have enough power with yours

Maybe i want try for a 10 first which will be hard with a manual plus I dont go drag racing I was mainly into Rallying over the years lol

Look at the old thread at what Skaife did with his ute 8 years ago with heaps less power than you have

Yea im entered into Temora this year but looks like I wont make it as Ill be at work. But I may it give to a mate to drive in my spot just hope he doesnt write it off lol.

There was a xr6 turbo stage three on wheels or some mag that did 307km/h. That would give you an idea what a commodore would need.
I've been 274 and the vx gts felt great. Another's 25 km would be reasonable with the basic aero, bigger wing and lower but you would need some 500rwkw like the xr6 had

Well in 2003 Motor magazine got 275 km/h out of a GTS and 270 KM/h from a CV8 (both stock) at Avalon.........how much has have these speeds been improved on with another 11 years of evolution???????

Surely the Hennessey Chevy SS would have a chance of getting there (along with most other built/boosted Commodores). I reckon that Hennessey would probably give 200mph a go if you sent him an email or FB message!

I don't think alot of you guys realise how much power it takes to get a commy to 300. They are bricks when it comes to aero, and the amount of power it takes to overcome that is huge

290 gps measured in a vz clubby and light does not even come close to describing what the front end feels like. Remember guys all these forces are logarithmic not
Linear. An extra 25 kph is a massive increase in everything.

Yes I agree but it depends how you look at it because plenty of the top speed runs are done over a set down measured distance (over a "measured mile" for example)

often doing a return run and using the average speed & given only a set distance before the start of the "measured" distance.

If it was just a matter of keeping it flat out in a straight line with no restrictions of the distance to wind it up on I think many cars could get there

(That is of course if you could hold them on the road at that speed)

Yep hit the nail on the head. money would be better spent on aero rather then power after the 250km mark as I guess it would be cheaper to make the car more slippery then more powerful.

Also as Ed eluded to how much road have you got? @ 275kmph like listy said he was doing you are traveling at 76.4 metres a second, at a guess I would think if you had the power your increase in speed would probably be in the field of 0.5km per sec, so that extra 25kmph would be taking you 50 seconds or more importantly 3.82KM, which is a very long stretch of road.

I think the best way to get a commodore up to 300km is to drop it out of a plane.

Nah, even that would not work

I remember watching something on Top Gear a while ago when they dropped a VW from a Chopper

& it did not drop anywhere near that fast, can't remember the exact speed of the drop but does not matter exactly but here is the vid...



Anyway I just :: "how fast would you fall if you fell from a plane without a parachute?" & it came up with


"if you fall out at 12,000 feet (about 2 miles up), you only have about 60 seconds before you hit the ground. In free fall, you fall at about 125 miles per hour (mph)
if you have your arms and legs extended, and at that speed you will travel about 12,000 feet in one minute."
