FPV's 351kw GT-F more powerful than HSV's 430kw GTS, How did this happen?

[macca_779]

I don't get it.

One is 351KW and the other is 430KW.
One pulls a max of 343.3KW on a happier dyno yet they says it it always has 351KW + up to 15% of fairy dust transient overboost.
One pulls a max of 322.1KW and has a 430KW badge.

So one only looses 3% power through the drivetrain yet the other one looses around 25%.

Sounds to me like they should put the LSA in the Falcon and have around 420KW on the dyno...

I'd like to see the graphs to see where the power is made, and can't wait for a track test to see how each perform down the 1/4 and around 1 lap of Phillip Island.

Ford quotes 404kw at the fly with max over boost. But yeah HSV still talks shit re 430kw

The main problem with the LSA is reducing the HP its so easy to make huge grunt. Wait for my dyno graphs coming up next week

No I meant a Commodore striped down. Why not? Plenty of racing fans here and probably a surplus of parts at the end of the run. So give is us a striped down race car for drags etc.

That's what the GTF is.....a stripped out.........lol

And I really notice people don't understand what fords transient overboost is. It's simply always ON. The engine will garuntee 351kws and depending on temps transient boost adjust that figure up and down. It'll stay at max all day every day if it's at a good temperature. Hence why they did 9 runs in all the above mentioned dyno tests for the ford and still had minimal heat soak.(tho it's winter). For a non inter cooled high output engine that very impressive. Espescially when it's averaging aproxx 20more rwkws then the inter cooled cough430cough GTS.

The LSA crate engine puts out a claimed 556hp or 408kw.
HSV claim it to be 430kw, a gain of 22kw. Does anyone know how they get the extra 22 from?
Also W427's with 375kw get around 280-290rwkw
While the GTS gets 20-30 more rwkw while claiming 55kw more!
It's either lost more kws through the drivetrain or the claimed 430 is a bit high??

That 556hp is the Cadillac CTS-V version of the motor that doesnt have the larger supercharger cover of the Camaro ZL1 version. The ZL1 version is the same as HSV and its 430kw

I was voicing here a few years back HSV given their supposed racing heritage should offer a stripped down lighter ballsy street racer for a different yet admittedly limited cliental and it never happened for a reason.

It definitely won’t now.

Still that Camaro is a good idea, just wouldn’t have the sales numbers to make it viable here.

The difference with the XR8 is it will have a reasonable kit just not the all out everything that is good that HSV has tried to incorporate into the GTS.

The XR8 will be a good valued stripped down (or should I say not as fancy) performance car in my books.

So at some stage between 5000-6000 rpm the Ford makes a peak of 20 more kW than a gts. The gts makes 30 + kW more anywhere else not to mention the big torque difference across the rev range. This is evidenced by the fact the hsv outperforms the ford at every point...

Just putting it into perspective...

[Uwish]

The GTS is also losing more through the driveline. FFS It was a bigger clutch / bigger Gearbox / and a 9.9" diff.
So the GTS will last all day long without breaking shit.
The New XR8 will be the bargin performance V8 of the 2000s.

Hold onto that dyno result mate cos it's the last victory FPV will ever have over HSV. One of very few might i add! So meanwhile while you wait for the tenth set of lights for the temps to be spot on to beat the GTS next you..............

[Plenty]

Anyway, everyone seen the new VX clubsport?

[whitels1ss]

To me it looks like an FG Falcon that someone has stitched some Mondeo rear lamps into.

No like.

True the GTS has so far shown to be the quicker but by the time you get to the next set of lights neither will have the time to get away from the other.

Anyway the GT F is now finished and the short term future will be the Ford XR8’s tangling with the HSV R8’s for the bulk of owners.

A stroke of the pen.....

[GTS LSA]

If anyone cares

My Auto GTS just ran 336.7 RWKW, it's 10 Months old & has nearly 9000km on the clock and its definitely not a happy dyno

By my calculations that's a 21.7% drive train loss on the claimed 430kw, I was actually assuming there would be a bigger loss than that, so at least in this case I would suggest that the 430 quoted figure is pretty spot on

Just my 2 bobs

And that XR8 looks horrible
