I seriously doubt you could call these a 'Premium Brake Alternative' they are still using the stock sized rotors for godsake, and the standard calipers. The size, and hence heat sink capabilities of the rotor is what makes a performance brake package, as the brakes are just there to convert kinetic engery into heat (with minimal sound). So if you dont have a larger rotor you arent really achieving this are u..

The prices are on the CAPA site..

Might just have to suck it and see.. as per usual

Im actually mainly interested in width, for traction, diameter doesnt really worry me, I am happy with 17's. I would like to try to fit 17 x 9.5's with 275/45/17 profile rubber.. ie Nitto NT555R's

According to CAPA the 3.5" exhaust system in stainless steel with a single rear muffler is $1800.. $2200 with two mufflers, the standard dump pipe is not replaced as it is not restrictive.

Thanks peoples, at the moment it looks like im going with the CAPA 3.5" system with a single muffler, should be nice and loud

I will answer your question, they have not modified the stock ECU, so how could they have removed the top speed limiter? Question answered.

Those are bloody nice wheels.. are those the factory premium brakes?

Take a look at some of their kits for the WRX and S15 to get an idea on pricing, as they havent got the kits ready for sale they wont have pricing as yet, but I would expect the 330kw kit to go for about 5 grand based on what I've seen from them in the past. The really exciting thing is that they are ADR legal so you wont get hassled by the cops / RTA

Can you give me the names of the 'quite a few others' because I need to ring around to get the best system I can.

I wouldnt expect to see the 330/390kw kits until June at the earliest considering that they are releasing the unichip 280kw upgrade in May..

What are the largest wheel / tyre combination that will fit under the back of a XR6 Turbo ute? Any experiences most welcome..

Ok so you think you can have a debate without proving which solution is more technically advanced? Isnt this completely counter-intuitive considering that this is exactly what the point of the debate is!?! What I believe you mean is without getting personal, a technical discussion about what is better/worse is completely productive and the entire point!

Ive been averaging 16.6/100km so far, only 650km on the clock and only city driving.

I believe that he is saying the factory computer will sort out the fueling and ignition timing.. pesonally im not entirely convinced they would have mapped every point above stock boost perfectly as the car was never designed to run that much boost.. then again if they were running higher boost during testing then they may have tuned the car with that much boost and left the mapping in the ECU.. either way sounds plausible really. Maybe street tuner can answer this

Street Tuner: I'd be very interested in the 1/4 mile times this thing can pull, but obviously its more of a quick cruising barge than a sports car, the torque reminds me a bit of a 454 chev Anyhow thanks for the infos.. much appreciated speaking to someone who has done the hard yards. PS if anyone is after a set of Nitto NT555R's for their car let me know as I can get ahold of them, I'm going to run them on mine for a bit of extra traction!

Street Tuner: I actually meant in the boost control department, I had an idea that Ford might be controlling how quickly the boost comes on via eletronic boost mapping.. I assume you guys are playing with the signals coming/going between the ECU and the wastegate actuator you may be able to change this to some degree? Why wouldnt you worry about the strength of the internals? Not being picky but do you have any information from testing or is this just a gut feeling.. I have spoken to one workshop in particular who think the rods are very thin, and the valve springs are prone to breakage, even with stock RPM limits. Assuming the engine internals are not limiting what would your next step be? I assume you would add the biggest FMIC you could fit in, add a turbo with %20-30 more airflow, change the inlet manifold and inlet piping to higer flowing items, add a T56 six speed manual gearbox and uprated clutch. I would assume this would require ECU modifications of some type, or a change of AFM? As an aside what does the AFM read at peak torque voltage wise..? PS: Some nutters out there will want to go a little more crazy than everyone else, and yes I am one of them Fijneman: I think its obvious that the gearbox is not going to withstand 1000ft/lb of torque, but as you claim to be from an engineering background I'm sure you would know that most components are rated conservatively in terms of what they can really handle.. and OEM's are naturally very conservative to be 110% sure that few warranty claims are made. Although the gearboxes may be rated at 450nm or whatever, keeping the fluid temperates in check will help greatly when pushing them slightly over their rated specs by 30-35%.

Thanks for that.. very good information, I'm sure everyone appreciates it!..

You must ask the tough questions I seriously doubt he will provide answers to the questions for 'commercial' reasons but I would love to be proved otherwise..

The unichip package will retail for around $1595 fitted according to my sources..

That is the airflow limit of the GT35/40 turbo supposedly. I seriously doubt you will see 480kw with stock engine internals however, then again I could be wrong, but I seriously doubt it! Damn things are really starting to heat up at the moment, I have a large wad of cash burning a hole in my pocket but I am loathe to go with anything until all of these guys have their kits out.. stuff paying for my own R&D.

The APS site has just been updated with additional falcon information: http://www.airpowersystems.com.au/falcon/xr6turbo.htm

What systems are currently available off the shelf? I am after a high quality stainless exhaust system for a XR6T ute. I am thinking that a 3.5" will be most beneficial for this size engine. I am interested in a nice loud, deep note, without nasty harmonics and droning.. so let me know whats around!

Street Tuner: Can you please answer the following questions: - Why isnt the factory computer remapped? Shouldnt high boost (11-12psi) mean that ignition timing needs to be retarded slightly to compensate for this? - How marginal is the fuel system, what safety margin is there here? - How well does the stock intercooler hold up with 11-12psi boost? - What scope is there for further boost increases and hence power increases? Is this possible on a internally stock motor? - Is a 3.5" exhaust better than a 3" exhaust on these cars, ie does a 3.5" system make make additional power over the 3" system? - Is the dump pipe off the turbo as good as is rumoroed or does it need to be replaced? - Is there any way that the boost threshold of the engine can be bought lower in the rev range? Even though the XR6T has less lag than most cars im sure a lot of people would like a little more bottom end if possible. - Can you possibly overlay your latest dyno over your initial dyno run so that we can compare how and where the torque is increased? Answers to these questions would be of great help to the XR6T community.. but I suppose commercial gain may be above all else I agree with the above, free discussions of a technical nature benefit everyone, and why not have some spirited discussion on such matters, after all that's exactly the kind of thing that competition should be all about..!?!.. but maybe I should keep quiet and uphold the party line or I may be put onto the commies' blacklist..

If airflow to the engine is a huge concern im sure you could vent the bonnet or put a scoop on the front of it.
