Vx Clubsport R8 And Xr6t

[RHR]

Erm guys...it's called average torque output - forget kw's for one second, and let's look what a turbo do in reality - it's a torque multiplier, and a very effective one at that...

So, when you compare your average torque spread through your powerband, with a NA V8 of say 5.7L capacity, you should kill him.

No contest. Why - well, see it works like this - when you have a 4l engine, and you boost one bar pressure, in reality you have a 4l x 2 capacity engine = 8l NA equivalent.

In our case with stock XR6 T, you are boosting roughly 0.5bar, or 1/2 atmosphere, and in theory you have a 50% capacity increase, giving same displacement as a 6L NA V8 - but, only problem is, you have the same peak torque than the 6L V8 NA Engine, but much higher average torque.

That is why nothing NA in the same displacement range with same peak power levels can realistically compare with a turbo engine, with the same calculated displacement.

So, a 4l turbo engine, producing 400kw and 800nm torque, doing 1bar boost at the inlet, should produce same peak power than a NA 8L V8, so close to 400kw and 800nm torque, except average power levels on the 4l turboed engine should be higher.

I am talking no race-prepped 8L, just something like a std 454 big block, not exactly 8L, but close enough for a comparison.

Hope it makes sense. Then again, it may not.

Jesus! The things you learn on this site.

And to the original postee, I did the same thing jumped ship and left Holden. Ive never looked back except to see one in the rear view mirror dissapearing rapidly into the horizon behind.

good info hey..

Whats the go with your sig??

Wow thanks MR Bean. I have printed that info out to a fellow work collegue who still thinks that the Standard VX Clubby will kill the XR6T in overall power. He agrees that the XR6T will beat it off the mark but after over 100 Ks an hour he seems to think that the clubby will leave it for dead. Its interesting to say the least.

Hey Guys, you are welcome - it is always nice to share information, and there's lots to learn on this site

Wrt my signature - well, something I read in one of my many Engine Books, either Smokey Yunick's Power Secrets or Blue Printing book or somewhere - will dig it up again.

Unfortunately my UTE will get some chemicals next week, just enough roids to take it to around 385rwkw's.....I will run daily tune of 350 or so, and for extreme thrill flash the max tune...

Unfortunately, that will have to do for now in my F6, need to assemble a decent bulletproof bottom end, like to do it myslef and not buy a pre-fabbed one.

Will post back next week this time, then at least the 1st phase of my planning would be complete. Would be nice to get some action happening instead of this boring 230 odd rwkw stockie F6....

Hi all,

In regards to a VX clubsport R8 v BA XR6T be sure to head to Eastern Creek Street Meet this Wed NYT 21/2/07!! My friend and I went last week to the drags, he had his car cutom tuned the day before and ran a best of 13.6 for the nyt against my 14.005 with only a new intercooler. Getting my car custom tuned tomorrow in Springwood ready for revenge !!! With similar setups should be interesting to see to will win on the nyt. Hope 2 see you all there.

If you run the 255 ls1 motor just before it hits redline in all your driving you will find it somewhat more responsive.. The difference is the torque down low we get use to in the turbo... Keep a big motor spinning fast and it is a different story.....

No lag .....

Go the T

A guy I know says his SS LS1 6sp ute (2004?) does 100 in 1st gear..... my T56 sedan will just reach 100 in 2nd. Just wondering if this dude is dreaming??

Ummmm... I would say yes!!!!

Unless he can run it to 14,560rpm then it would be no problem to get to 100.2 kmh

Hay guys if it wasnt for tht T the F6 US X Expensive Daewoo lovers wouldnt be HERE,Bring on the MIGHTY F6.

I've recently gone from a BA XR6T to a BF GT and the T feels quicker and probably is. The power in the V8 comes in much later and the car does feel heavier. My GT is still new but after the 3000 service I'll give it some stick and see if my thoughts change. As great as the GT is, and I think it is great, Ford have kicked massive goals with the 4L Turbo. A true legend in Aussie motoring.
