Motor Hot Tuner

SSbaby · 23-03-2005, 02:11 PM

A really good read. It has a feature on edited versions of LS1-powered VZ SS and Boss GT Falcon. Both vehicles were edited and at dynoed at Street Tuna's workshop. The VZ SS ended up with 240 rwkw post edit while the GT dynoed even better at 258rwkw after tricking its PCM with the CAPA flasher! But it was the Holden with more impressive on-track performance... 12.7s, 0-400m while the GT was not far behind at 13.4s.

There's heaps of other good articles for both Ford and Holden fans, alike.

The Tuner version of Motor is the sort of mag that we enthusiasts have been screaming out for for quite some time. I'm glad someone is listening. Top effort, Motor!

I have I think the first edition and its not a bad read.

From memory it had the APS XR6T Phase 3/ kit in it.

XRQTOR · 23-03-2005, 02:37 PM

12.7-13.4 IS A BIG DIFFERENCE ON THE TRACK. The GT has an 18 rwkw headstart and loses by 7 tenth's. Does it show the 6o" times and mph for each car.

**post edit times quoted**

GT
A4
0-100km/h: 6.22s
0-400m: 13.41s @ 169km/h

SS
M6
0-100km/h: 5.56s
0-400m: 12.74s @ 176.5km/h

Steffo · 23-03-2005, 03:35 PM

That GT seriously sucks... 258rwkW and it goes 0-100km/h slower then a stock example should? Either that or its got major traction issues... or maybe the driver...

The SS did really well though.

Sox · 23-03-2005, 03:53 PM

Sounds about right to me, the GT is approx 150kg heavier than the dunnydoor.

Throw 2 people on board the dunnydoor, and watch it run 13.4 or worse.

My intention was to gloat about a magazine that IMO is great reading... not so much focus on the relative merits of the vehicles tested. The end result of what was achieved with edit is what's important. Owners of both marques now have relatively cheap ways to increase performance without puting a hole in their hip pockets.

Some Ford owners have already seen the effective gains.

**FTE217** · 23-03-2005, 04:24 PM

Exactly right Sox, the Commy guys always crow about their off line speed and good luck to them thats what they got. Lighten up the GT to the SS weight then thats a true comparison.
What is the times and weight of the R8 anyone ?

SSbaby · 23-03-2005, 04:25 PM

OT: BTW, to Steffo and others,

There is a guy on the other forum with an edited Stato with 'only' 210 rwkw that manages 13.3s quarters on street tyres... again and again. Nobody believes his car could run the times claimed... until he produces the timeslip... and he doesn't care what anybody else thinks.

Numbers aren't everything!

Back on topic...

GT 8888 · 23-03-2005, 04:30 PM

I noticed that Motor were using a G-Tech to measure the times. Is that what they normally use?

SSbaby · 23-03-2005, 04:40 PM

I thought the Correvit was the standard of all timing equipment? I was also puzzled when I saw the same pic.

Perhaps Mickey T could explain?

SSbaby · 23-03-2005, 04:49 PM

Have a look here at G-Tech's website...

If you are getting strange results, the result in all likelihood is one of the following:

incorrect vehicle weight
mounting system not tightened, or cracked/broken (lots of vibration)
slope/grade in the road
severe vehicle vibration
wind (head or tailwind)
clutch slip, wheel slip, wheel hop, torque converter slop, bumps on the road
incorrect driving style

ozzyjim · 23-03-2005, 04:50 PM

So let me get this straight, they took a stock VZSS, stuck on a edit and ran a 12.7?

Jim

ozzyjim · 23-03-2005, 05:06 PM

Also, the edit for the SS makes a MASSIVE 40+ RWKWS?

Jim

EFFalcon · 23-03-2005, 05:37 PM

haha, everyone complains about the GT losing by 7 tenths.
yet the GT was an auto and the SS was a 6 speed.

SSbaby · 23-03-2005, 05:43 PM

The gain for SS was 16 rwkw while the GT gained 21 rwkw. I guess the SS was healthy to begin with but what the figures DON'T reveal is the way the power (torque) is delivered.

Not forgetting that there's other things in a tune which we care not to talk about like the torque truncation. In the SS, if you bounce off the rev limiter it usually means you'll run a slower time; if you hit the rev limiter in a stock GT your head will virtually crack the windscreen such is the severity of it's intrusion! Btw, TQ Management on both edited cars was disabled.

Um... Auto is faster when drag racing

Is that Voodoo by any chance? I have met him @ Willowbank before, I dont know the exact numbers mind you but he didn't strike me as a fairy tale teller

No, his nick is 'iwantahsv'. His car is bolt-ons only with edit.

If we compare LS1s to Boss' then I reckon the best way to do it would be to compare Stato to GT... that way we stop talking about the weight variable, which is significant and does impact on overall performance... but that's not GM's fault!

Racecraft · 23-03-2005, 06:17 PM

Ahh OK I think Voodoo runs a Stato Luxo Barge too that also has bolt ons and an edit that cuts some respectable numbers considering the QLd climate at the drags...

So to agree with you entirely SSBaby the wieght is not the be all and end all it is how the power is delivered is just if not more important

ozzyjim · 23-03-2005, 06:21 PM

wow, i cant believe the ss (250kw) makes the same power as most gt's at the wheels and only losing 26kw through the drivetrain! Then run a 12.7 at that! Considering its a 14 flat (according to motor)car standard that 16rwkw`extra must be something awesome!! I reckon all the holden boys at the private drag day with heaps more mods running the same or worse times would be mighty ****ed.

Cheers
Jim

Rick.

I dont think thats the point.
There compairing a $45000 SS.
Against a $65000 FPV. Just think if thay would have got a new Clubby and did the edit thing...No wait....we dont need to think about that..

:
Allthough at the Australian Muscle car shootout at the Creek, the Holdens didn't fair that well. So mabe it was a bit of driver error......

Only if it's setup for drag racing only, that is, short gears, slicks etc.
Most typical factory road cars run quicker times with a manual.

BA SSS tends to be faster/better then the manuals.

he has been using them for years, i thought a race track is where you get your ET slip...
G-Tech pfffftttt

Not for the V8's it ain't, the extreme torque reduction on the autos see's to that.

The SS is $51k, the GT is $61. Can you even get an edit for the Gen 4 yet.

Yes, but this GT had BOSS edit, therefore no torque reduction.

Sure, but it still had standard diff ratio and a standard torque converter.
No question autos are better for drags, IF they are set up for drags.

Typical standard road cars will almost always do the 400m quicker with a manual. Only turbo cars may break this rule as they dont fall off boost during the gear change.
