DJR 320

[Rob 18]

It's been a couple of months now since the beast was released, but I still have'nt seen any performance tests yet (o-100 etc) anybody heard or read anything on the 320?

 

[Mitchell]

Dougy's next feature is probably going to be the 320, so we'll see if we can get some performance charts out of the team...

 

[TRU BLU]

Have they sold any to the public? As i haven't seen any on the roads in Sydney or Melbourne

 

[Doug]

As of February, when the team released the Konica Cars, they had 12 confirmed orders/sales. As Mitchell said, the next feature will be a look at the 320 with current performance and sales figures.

 

[Rob 18]

Look foward to it Doug. Thanx.

 

[Rob 18]

Any one read the test on the 320 in the current WHEELS issue. Must say I'm very disappointed. 0-100 6.9sec?? & 0-400m 14.6sec?? What happened with all those 320kw's???? I think my XR-8 ute could run better numbers than that & it only cost 40K compared to 90K for the DJR320. WHAT HAPPENED!!

hi rob hmm the comparrison in Kw to 400 metre mark would be improved if given a different final drive ratio and tyre size it would be a lot quiker than you think not knowing what has been done to your xr8 if it is a standard xr8 sorry to say no you would not keep up with it

 

[Rob 18]

G'Day Mick, fair point, but when you look at when WHEELS last tested an XR-8 sedan ( I know it's not a ute) it ran times of 0-100 in 6.2sec & 0-400m in 14.5 which quicker than the DJR 320. Don't get me wrong, the 320 is a fantstic piece of machinery but, I thought it should run quicker times than that!!

Intresting Rob do you know if both the 320 and xr8 are auto or manual and also the tyre size on the rear is different i just dont have the wheels mag on the xr8 results to compare all the info just curios i guess, and what series xr8 it is. thanks....p.s rob do you also no at what r.p.m that there claiming the 320Kw

 

[Doug]

Now this is getting interesting. I, in my infinate wisdom(not) had no idea that tyre size affected performance. I still plan on a feature on the car - but a complete one rather than a re hash of whats already been published.

 

[mick]

G.day Doug your correct tyre size has nothing really to do with outright grunt i probally didnt explain what i meant.Over a measured distance lets say a quarter mile a car that is 2000(lbs) and has 350hp at the rear wheels it would have an aprox power to weight ratio of about 5.7:1 an quarter mile E.T of about 10.14 at aprox 131 (mph) now this is where tyre size and diff gear ratio comes into the theory when the power is at it,s maximum lets say 5500rpm it would require say a rear diff ratio of 4.56;1 and a rear tyre size of a 36 to acheive it,s time of 10.14 and acheive it,s 131(mph). Now lets say we change the rear tye size only we will leave the rest the same but with a smaller tyre, at the end the quarter mile it would be all over it would have already reached it,s maximum rpm of 5500 and bouncing of it,s rev limiter before it gets to the end,where if we did drop the tyre size to say 28 the maximum speed the car would do would be around 101(mph) there fore it would not acheive it,s e.t of 10.14. The hardest part of building an outright beast for road use is 1)fuel economy if they where to change say a diff ratio or tyre size the fuel economy would be a shocker 2)The thing sitting on a very high rpm on the freeway,s would have to decrease the engine,s service life but on the bright side it have a very nice tone from the exhaust. Hope that explains the theory okay if not i can email you the formula to work it out...... thanks

 

[Doug]

Cheers Mick - I get the idea now - basically by increasing or decreasing the diameter - like when your low profile road tyres throw your speedometer out.

 

[mick]

That,s about the size of it Doug from memory the xr8 has 17inch rims and i think the 320 has 19inch rims good chance im wrong and not sure of the weight differance either if there is one.Hmm not going to be liked here the quikest 4 door production car up untill about 4 years ago was the phase 4 xa falcon 72-73 that rolled off the factory floor untouched and ran a quarter mile time from a standing start of 14.2 seconds that was 30 years ago .Upon saying that, the legal red tape comes into it and the Australian Desighn Rules today on emission,s is a lot tighter than back then.

 

[Doug]

Mick, I think its a blessing you mentioned the XA Phase 4 and not the nissan gtr - can you imagine the uproar

Both the XR-8 260 & DJR320 are both manual Mick. The XR-8 260, when they tested it on the 03/03/03 ran on 18" wheels & the DJR320 obviously runs 19" wheels. They claim 320kw at 5300rpm & the 320 is 35kg heavier than the XR-8 260 also Mick.
Probably the most disappointing thing about it is when they tested the 320 in the current issue of Wheels, they compared it with the GTS300 which ran times of 0-100 in 6.1 & 14.2 for the 400m (which is not as quick as it should have been either) & it basically made the 320 look slow!!

 

[mick]

Thanks for that Rob i will just wait for Doug,s article on the 320 i am very suprised . Did not know all of that, just want to know all of the info
Also any chance of finding out what the difference of torque is in Newton Metres is, if it is given and what rpm Thank,s

 

[Rob 18]

540 NM for the DJR320 at 4000rpm Mick & 500 NM for the XR-8 260 at what rpm I'm not sure but would be similar revs I would think to the 320.

 

[Henry]

Wheels also noted that the 320 had a shorter diff ratio than the norm (due I think to it's particpation in the Holden/Ford rally thingy); they felt that the subsequent extra gear change over the quarter slowed it a poofteenth over what it would potentially do with the taller (standard) ratio.

What other colour/upholestery choices are availiable? I like to see one that's BLUE.

Nice deep red 320 iN Performance Ford Mag the other day coming out of the Herrod Motorsport Shop.
