R34GTT Vs XR6T!!!??!!

[someonestolecc]

blah I don't believe this thread is still alive.

My personal theory is - one is a falcon, one is a skyline.

That's really the only thing you need to think about.

[psybic]

Nice work on the decision...

Just a point I would like to make.

I am sooo sick of people looking at the specs of Jap cars and going, hmmm only 206kws....

You know they have a documentation limit of 280ps over there right? Ofcourse everyone does.

Thats why GTR's have 208kw* twin turbo supras 208kw* 300zx 208kw*. we all know this power figure is wrong, so why use it in a comparison?

I don't know for sure, but I reckon you would find the R34 GTT would not be as far behind a XR6T on a dyno as the figures mentioned would suggest.

[jazza08]

As much as i hate to say... A GT-T wud be a fair way behind an xr6 turbo dude! Ive seen an intercooler + exhaust and it came up with 170rwkw, from what ive seen xr6 turbos with exhausts get much higher figures than this?

[psybic]

Fair enuff...

Does anyone know what the XR6T's do come up with tho?

I wonder if they would be over 200kws...

I just doubt alot of Ozzie power figures... Have seen results for a VS V8 which should have 168kw at fly come up with under 130 at wheels after exhaust work. And wouldn't be surprised if the big power battle holden and ford have been having latley see their power figures a little optimistic... especially the way they actually drive on the road... they aren't as quick as you would expect...

[jazza08]

No i agree there, they are heavy bastards thats why! lol

However the xr6 turbo can come up with crazy rwkw figures with very little money put into them, mind u they dun look near as good as a 34 and cost more.

[NJR 34GTT]

Stock Xr6-t pulls 180-190rwkw on the dyno.

[zymotic]

stock manual GTT 150rwkw?

[paulr33]

at one of our dyno comps in vic, they had a stock xr6 turbo run 199rwkw

A VS V8? Get with the times my friend. The car was probably used as a paddock basher....

If anything Ford actually under quote their power figures. Don't think that just because it's Australian delivered doesn't mean it can't punch out the numbers.

Take a look at www.fordxr6turbo.com and you'll see what I mena. 280rwkw is nothing and costs bugger all for these cars. No mucking around with bigger turbos, intercoolers, ECU's, cams blah blah blah $$$$.

I have just finished flashing my dad's XR6t with an 8psi map and let me tell you it pulls like a freight train. Might try the 10psi map with decent fuel in it very soon. All for $1200.

The R34 might look better but it certainly does not match the power of the XR6.

[zymotic]

all well and good as long as it gets it to the ground

more interesting for me to see how it compares to a

more comparable larger capacity engine like VQ41DE

as in V36 Skyline GT

330ps @ 6000rpm and 40kg/m @ 4800rpm

add a turbo and compare that to the barra turbo bit

fairer i think

poor little 25DET

[NJR 34GTT]

Enjoy blowing your engine with the 8psi or 10psi maps.

Injectors and fuel pump way out of capability at those levels. Valve springs and the aforementioned need to be replaced before you run that sort of boost on the XR6-T.

Although it is scary how much power difference the edit can make.

My point was the figures were low... similar aged vehicles and the Jap car held higher numbers than the good old tough Ozzie V8. I certanly wasn't suggesting a VS is new or some sort of bench mark.

Ofcourse I'm not saying XR6T's aren't awesome, I reckon they are the best Australian car ever. Jap cars still seem to do more with the engine size for fuel economy and price IMO.

We'll see what happens at Powercruise. The GTR will be there, stock as a rock. We'll see what the 14 years newer, more powerful, more expensive stock XR's can do. :aroused:

[slow13dude]

Some people are forgetting that the Japanese deliberately used smaller displacement engines with forced induction for reasons like weight and racing class restrictions.

It's all maths, of course the XR6T has more power potential than the Skyline engines, simple displacement + forced induction.

[psybic]

Yeah, the XR6T is a monster. My point was more about the original question of which car to get. I feel that the Australian cars don't do as much with their engines as they could.

eg. SR20DET makes about 180kw+ in the S15. twice the capacity you might hope for somewhere around twice the power in the XR6T, but only gets another 80kw's. Its more, just not as much more as I think it could be if Ford tried harder... I guess they didn't want it to over power the XR8...

LOL, yeah I'm certain Ford knows that forced induction beats NA and the power was deliberately kept conservative and below the V8 output. Lots of V8 bogans out there that would have hurt feelings if the XR6T came from the factory with more power than the V8.

[jazza08]

The xr6 turbo was probably more aimed towards the import owners who now needed a bigger family car that had the tuneability a turbo engine can provide! The xr8 lovers will generally always love their v8s so Ford wouldnt change that.

Edit is quite safe.Valve springs on a XR6T vary but mines making 300rwkw on stock springs.Injectors seem to be good to about 240rwkw.

These cars had a few problems with build quility but thats mass production for you.

if you guys have any questions on the XR6T i will gladly answer them.

Cheers Darren

[FPV T6]

if you want to see the how much power the big 4.0 litre makes,check out the nizpro XR6 motor they built.It had 1100 plus Hp.

[FPV T6]

To answer any questions on performance times of the XR6T,Here they are.

14.5 to 14.0 Auto

14.3 to 13.8 Manual

They seem to make around 180rwkw to 200rwkw standard.

I had a R33 gtst with pod filter,Full exhaust and 10 psi boost and just got beat by a stock XR6T comming back from willowbank.

If alot of you guys are from the gold coast you will most probaly see me out then.

You wont miss my number plates FPV T6.

[Vuster]

FPV T6. Your car is not a FPV though? Have you got the GT stripes, bulge, and wing?
