Falcon Turbo six, most power potential from factory in the world

[Eaturbo]

As the title says, is the Falcon six cyclinder turbo with say a manual gearbox the best Factory turbo 6 Cyclinder engine ever built. I mean the supra and GTR were fast but there factory turbos were terrible. As a stock engine with say just injectors and inter cooler and fuel pump was this engine the most potent engine made with regards to stock turbo and stock engine. I have heard of 400rwkw with a stock BF OR FG Engine on E85 with just waste gate ported. I can't think of another car world wide that with stock engine and turbo can make this much power without changing the turbo or rebuilding the engine. Could it be that the Aussie 6 with turbo is in fact the best turbo 6 to ever leave an automotive factory with regards to power output potential with only tune and some bolt ons. Any comparison you have must retain the factory turbo. Maybe we have become all to use to having the XR6 turbo and actually forget what we have.

I would say yes. The RB26 and 2JZ can get to around 400rwhp I think with the standard turbos. The Ford goes well past that.

I don't know if there are any other 6s out there with big power. Maybe the Euros.

[sexyxe]

Bmw m4?

[barnz_xr8]

2jz supra's had Manley h beam rods stock and forged pistons, so the power handling potential is there.

[barnz_xr8]

but you are right, damn even bf xr6t's stock turbo and can make 330rwkw.

[ravenhard]

R35 GTR has 404kw stock from the factory at the fly. I imagine could go a whole lot more with tune and minor upgrades as well

[FPV GTHO]

You can't say one car had a terrible turbo and turn around and upgrade the terrible parts on another

[Stefan]

911 turbo 450kw+, Nissan GTR 360kW, BMW M3 316kW. No good?

Exactly, if it's fine to do valve springs and fuel pump on a Barra then it's fine to chuck a decent turbo on another motor.

[Falcon SXR8]

The fact that the inline 6 can even be compared in this group of engines is praise enough and if you factor in cost its even better.

Not really, the R35 GTR is the closest in capacity that has been compared, and is still smaller.

[99AUXR]

Hmm Im going to say cubic effiency the RB26DETT, 2JZGTE and especially the VR38DETT are all further ahead.

As for power handling of the stock internals Im going to call them all out as being better again.

[Mont5.0]

Maybe change the thread title to Australian built and you may have a contender, not the world.

[FPV414]

There's a guy on here that's a run 10.99 with 390rwkw on E85 I think. Used stock cooler and exhaust, but had valve springs, dump, cat and E85 fuel system. I think BFB that is amazing. It's not going to hold together for too long but if you're sympathetic it's not exactly and unreliable set up too. I've know BF F6's to be had for as low as $11k, add less than $3k in mods and tuning for a $14k 10 second car - with all the creature comforts that a BF F6 came with.

[Eaturbo]

What I'm saying here is that while cars like the R35 GTR and BMW M4 might be fast stock, I don't think theres much in the way of getting big power out of them without changing the turbos. Again one could say that these types of cars are not even really a fair comparison but as I did say the best in the world it's still a fair call. There are guys I know making 450rwkw on a stock engine and turbo FG F6 on e85. I don't believe there is any stock turboed GTR's with stock turbos doing this or for that matter any other cars with Stock turbos making this much power. Valve springs are needed in any car making big power no matter what, check out Nismo or Any other hot euro tuner. So to say you can't change parts on one and not the other is not the point I'm trying to make. What other stock engine and stock turbo car can make 450rwkw and let's be honest the only close contenders are 3 to 6 times the price and even than it would be a very close call on if that was even possible. Maybe just maybe the best ever volume built engine of all time for power potential is built right here in Aus. Now would it be that bad if it was .

Value for money can't beat the turbo barra, just imagine what the barra could have been with further development.

Yeah imagine if they'd gone Ecoboost with it with direct injection and the Ecoboost software which is the secret to the Ecoboosts power.

[arronm]

Yep Iam a big fan of the turbo 6 cyclinder

[matador]

Top cars.. crazy fast with basic mods.

[CAT600]

Fastest stock turbo, stock engine R35 is 9.73 @ 142mph and it's still a fairly hefty car. Damn the 2014's run 10.90's from factory.

But yes the Barra is a great engine no doubt

[1TUFFUTE]

How about you take all mods except "tuning" what's factory, out of the equation. No upgraded springs, turbos or exhaust........just cpu upgrades only!

[mik]

bang for buck it is hard to go past the big six, how much torque do these other expensive turbo sixes make ?
have a look at this bad boy , not far from breaking into the eights.

I think most, well me anyway, were simply responding to your blanket statement in the OP.

But bang for your buck the I6T has no peers, I see great results from the S/C 5.0, but a 5.0 car is still a fair bit more expensive than what a XR6T or even F6 can be picked up for.

I'm hoping they don't increase in value, so I can keep plucking off cheap daily low km barra 6Ts for a few years to come.

wouldn't it be preferable if it was a shorter stroke motor? with the long stroke, it will always be a tractor motor..

:P

That's the beauty of the engine, torques everywhere. I don't see the point of short stroke high revving buzz box that is largely off boost and needs it's neck wrung before anything happens.

I'm thinking just like you. Take the four stroke motocross bikes prior to 2000 that had strokes longer than the bore diameter and then all that changed in the early 2000's when they went to over square bores with bore diameters way bigger than the stoke length and virtually non existent piston skirts and instantly producing heaps more KW's and more revs, it was a game changer.

This might be valid in a naturally aspirated engine but not so much when turbo. I am a motorbike mechanic and those old long stroke bikes you talk about are still running. These new generation short stroke no piston skirt engines are blowing up left right and centre. Just look up eBay or gumtree to see the rolling chasis engine in bits four strokes blown up due to engine failure. They might be powerful but they don't last. Look at the Falcon motors which still do over 200,000kms. You look up car sales and every second R32,33 GTR and WRX STI has a rebuilt engine with minimal kms. The secret with the Falcon engine is that great performance is available under 4000rpm. Even if there is one or two engines that are slightly better than the Barra Turbo, they are dedicated sports cars and engines with millions more dollars spent and very very expensive to maintain and rebuild. Anyone ever priced and R35 gearbox or brakes, there worth more than a second hand XR 6 turbo. Not to mention you can buy parts for a Falcon from repco.

It always amuses me when the 4.0's long stroke gets brought up. It's only 7mm past being square.

[mik]

Even the the earlier falcon 6`s where a pretty low stressed torquey donk, i look at my own vct xr6, 15 years old , same head gasget, timing chain , still pulls like a train and is still very quiet for engine with some years on it and 235,000 k`s and many of them hard k`s.
a few weeks ago i noticed i was using a bit of coolant , i thought ah well the poor old thing is way overdue for some love, i put the cooling system pressure tester on it and it turned out when i did a radiator flush and removed the thermostat not long ago i didnt tighten the radiator hose on it enough and it was leaking a tiny bit ...... still going strong ..... what a grouse engine ! we will miss the falcon 6 when it goes.

In the old days Ford did a 250ci and 200ci version of this engine. Imagine a turbo version of the 200ci.....
