Supercharged HSV? - Part 3

[jc_sv8]

How about an HSV for the road and then a second one for the track only!
Spend another $50K getting it right and you'd still have change for a couple of 44Gl tanks of E85 and a few sets of track rubber.

Then we've spent the same amount - after that put them both down the 1/4

In the past year or so everything has shifted by about a second ... 3's are the new benchmark, 4's are no longer solely the domain of the supercars, 5's are everyday sportscars, 6's are runabout hatch backs!

Unbelievable really, just when you think they can't possibly get any faster ... surely now they can't possibly get any faster!

Apparently the Nismo Nissan GT-R will be capable of a sub 2.1 sec 0-100km/h... It really is unbelievable. When i think back to 2004, my XR6T had 300rwkw and it felt like a rocket. Imagine what a 0-100km/h in about 2 seconds would feel like!!

I think the GTS is great for what it is. A large RWD aussie sedan, capable of some fantastic times/performance...

My old man bought an e55 brand new in 1998, back then was one of a few sedans doing 0-100 in sub 6 seconds.

Incredibly these things in 2013 are heavier and albeit with more power but have shaved off almost 2 seconds, imagine if they were 500kgs lighter!!

Just go's to show you Torque wins races 800nm@1750 rpm is crazy.

I notice that the GTS doesn't hit peak torque until over 4000rpm. Even the GT makes peak torque about 2200rpm.

Can anyone shed light on why the GTS makes peak torque so late, would it be to assist with traction? Or other reasons? Is it mechanical, or engine type? Obviously a huge amount of peak torque early on is harder for the car maintain traction.

Fuel consumption on the test is very interesting

I guess this isn't really an issue if you're getting 80-90% of it at 2,000-odd rpm ... I'll reserve judgement until I see a chart plotting it all the way along the rev range.

MkVIII Golf R is supposedly 0-100 in 4.9km, thats amazing out of a little hatchback.

yeah i suppose, i didn't really look at it that way, especially with 740 odd Nm!! Even 80% of that is near on 600nm... Will be interesting to see how it does go in the hands of owners and on the dyno/track.

Had a read of the Wheels Mag article and in terms of acceleration the HSV stays with the AMG up to 60kph but then falls behind. I suspect part of the problem is the HSV's taller second (123kph vs 104kph) and third gear (169kph vs 155kph). Forth gear looks pretty similar (219kph vs 217kph and 5th/6th/7th all top out at a limited 250kph.

I wonder if a shorter diff ratio would help the HSV beat the AMG over the quarter mile? Is the manual actually quicker than the auto for HSV over the quarter? I wonder if the auto is actually quicker with the snappier changes.

I was more impressed by the lap time and often higher cornering speeds of the HSV, especially as the AMG is 86kg lighter, 109mm shorter and 45mm narrower. That's a superb effort by HSV.

Cheers, Matthew

Haven't read that analysis,.....but on a $ for $ basis, how good does that make the GTS?.....I mean, for the money, NOTHING comes close.

Yep, dead right. Even if you were to knock out the "Australia Tax" out of the AMG it still wouldn't come close to the $93K the HSV is, and it isn't an all round better car.

Oh, and another difference between the AMG and HSV, HSV has the same make of tyres as the AMG but the rears are 10mm narrower than the AMG (HSV: 275, AMG 285). Along with the fact that HSV is a bigger, heavier car with a worse torque curve, to achieve better cornering speeds and lap time shows HSV have absolutely belted AMG in chassis set up.

Read it on the plane coming home from work. The fact that the GTS was faster 'round Winton (GTS: 1:40.9 vs E63 S: 1:41.2) in the hands of John Bowe certainly does give it some credibility. General consensus is the the Mercs motor is stronger, but the HSV has the better of the fight when it comes to handling.Fairly soundly trounced on the (wet) strip though, but a very positive review of the GTS overall (but then it is wheels and they have a reputation of being pro holden), well worth a read.

Interesting to note that the SV6 vs XR6 comparo a bit later on listed handling as one major area where the SC got beaten by the XR. Seems a bit odd.

[Jag530G]

Yep, the AMG's acceleration is a classic example of the fact that the most important thing from an engine to deliver best acceleration is area under the torque curve, not peak power or torque. The AMG basically hits peak torque at around 1800 rpm and stays up there, the benefit of twin turbos really. The HSV just builds to its torque peak, just the nature of supercharging I guess.
