HSV confirms 6.2 litre heart transplant

Apparently they've peaked at a de-tuned 317kw to avoid making changes to the diff and transmission? Once the engine is wound up it should hit 330kw.

[Sphinx]

torque still set at 550Nm due to drivetrain constraints. They need to get some corvette hardware in there!

[1991_Vn2nV]

Is the hardware constraints for real though?

Im sure there are VE HSV's out there that have been modified making way more power than that.

What about the Walkinshaw packs etc.?

[Sphinx]

don't know about the walky packs but I'd reckon for warranty issues they keep the torque figure the same, then again I could be wrong. Anyone know someone at HSV that can confirm why the torque figure is the same?

[Sedat]

I reckon the GTS should get the the 6.2 transplant only and leave the clubby's as a 6.

[Full Spectrum]

Anyone that ad's Exhaust to there E-Series HSV would top 550Nm easy?.

Maybe the Engine only has same torque but a flatter torque curve?. Some say the Ls2 was a little low down low.

[azkwazere]

possibly, they need to start adding more solid drive trains so they can up the power.

Stronger box and diff... heaver clutch on manuals and possibly factory shift kits for autos.

aZk.

[1991_Vn2nV]

They have the W427 driveline if they need it (though it may be a little expensive).

[UNKNOWN]

If you can afford an LS2 or 3 car I dont think moneys a problem!

[1991_Vn2nV]

You wouldnt wanna go adding 5k or something to every model though.

[BANKS]

what differs from the holden e-series drive train and the corvette's? surely being GM they'd be able to look at some drawings and stats to modify the e-series drive train to except more power and torque?

The problem with this is that they arn't making the 6.0 ltr anymore. Why don't they just make an 8 ltr

They wouldnt wanna add to the cost too much. Plus, its only a running change not a series change so to go to all the effort of a new diff etc... (the trans can handle much more than what the LS3 is currently offering so thats no biggy).

But plenty of guys are running alot more power through their E series cars without problems so its probably just an excuse. The LS1 started at 220kw and finished at 260kw so I assume we'll see a similar thing happen with the LS3.

that makes sense, maybe the next series then maybe they should just skip a few and go straight to the LS7 lol

[Cursed CX8]

flatter t-curve, does this mean the engine will deliver torque with a more even distribution than the ls2? or does it mean that the car will deliver 550nm at a lower rpm?

[1991_Vn2nV]

With a more even distribution.

[Cursed CX8]

man thats going to feel like a massive engine.

its interesting that ford develop basically the same power from a much smaller engine though

AHHH!! my virgin eyes!! whats the stats on ford new engine compared to holdens?

[1991_Vn2nV]

290kw from the XR8

315kw from the FPV GT's.

The engineers at Ford and FPV have alot to be proud of, but even so the BOSS engine is at its very limit.

The LS3 on the other hand, is only at the beginning of its capabilities and is capable of a hell of a lot more than 317kw. Plus, the BOSS engine doesnt seem to make much of the peak power. A 270kw SS was quicker than a 290kw BF GT, so don't be fooled into thinking a 315kw FPV GT will threaten a 317kw HSV. They'll still wipe the floor with FPV's V8. As always, the real threat will still be the F6, particularly on a track.

thats wat i want! im sick of the gts being the same as the clubby...bring back the days of vs when they were 5.7 and the rest were 5ltrs lol

[Sphinx]

GTS isn't a real GTS.. just a clubby with MRC. GTS-R on the other hand is another story.

Boss's engine are more advanced arnt they? compared to the LS series. Running DOHC's, VVT etc

I remember watching a show where they tested an xr8 ute against a xr6 turbo ute down a quarter. the XR6T had him 240m down the track, wasnt till the XR8 got on its legs that it started to catch up and overtake. Around my area theres boosted up XR6T everywhere that i woudnt risk the embarrassment of having a go at, i wouldnt hear the end of it lol

good point on the chev's having more in them, FPV make it hard to improve and modify

Technically yes the BOSS engines are more advanced... but I see it the other way.

The LS3 is
- More fuel efficient despite the larger capacity
- More powerful
- Cheaper to build
- Has superior Torque and Power curves.
- Has a higher rev limit than the BOSS.

The cost is the interesting part, the 6L and the LS3 also are cheaper than the Alloytec engine. So when you consider the $$$ you pay as a premium for a V8, thats a considerably more profit going straight into Holdens pocket.
