I thought the beams had 150rwkw. You should be able get an extra 20kw. Just need to get more air through the motor. Good set of headers and a exhaust to extract them gases out that should be 7- 10kw. The factory ecu are very, very, safe tune. For drivers that might do full acceleration in top gear in low rpm, great for creating knock, Car maker have to anticipate stupid drivers. With a good ecu tune you could get 10-20kw and increase torque out of a motor or just do a simple fuel regulator with AFR Wide band OS sensor then adjust your AFR ratios should be about 10kw gain.

Apparently the stock headers are very good already. People on the Beams forums have tried aftermarket option with little or no improvement, some have even reported a slight drop. I don't know what can be done with a stock ecu, but the cost of an aftermarket ecu probably wouldn't be worth the small gains. A better exhaust is on my list though. My first focus is on basic handling improvements, and trying to improve the nut behind the wheel (me).

It's harder to drive a high power car that is not set up right than lower powered car that is set up right.
The guys with racing slicks or semi slick and good brakes should be faster than those with street tyres and standard brakes it's about corner speed. As I counted last there more corners than straights at Wakefield.
When I last race bikes at Mallala there where guys with lower powered bike doing faster time than the higher powered ones. Just because of suspension setups and tyres.

Unfortunately nothing written here is true about the BEAMS. The power figure is 147kw at the engine not wheels for a redtop such as Ricks and 154kw at the engine for the Blacktop from the Altezza. About 115rwkw for a Blacktop and less for a redtop stock. These are highly strung engines stock and gains are not as easy to have because of this. Check out the stock 4-2-1 extractors on the Blacktop to see what i mean.

Great cars, the perfect all round car in my opinion. Hopefully be getting the missus into one in the future myself.
Hello tow car!
They seem CHEAP for what you get also. 2700kg or thereabouts towing capacity, so more than a prado more refined than a prado, same cost or less than a prado and more oomph than a prado. I guess the only thing a prado does better is off road, but I hardly do that, I'll keep the landcruiser around if I want to do off road anyway.

In all honesty they're good off road too. If i could find the go pro footage of the 4x4 course i was on in NZ with them you would be shocked what they can do even on the 21 inch road wheels. We were all shocked that is for sure. I towed Kens AW11 up to MR2TC 2012 in a petrol 3l (190kw) version and fully laden, AC flat out, on cruise control we sat on 110kph speed limit all the way (only had to go down one gear) the diesel you would not even shift down. Towing your race car you probably would not even feel the load out back at all.

Don't buy a truck for a tow car. They chew too much fuel. Just buy a car to tow with. I tow with a sv6 commodore.
I just don't get the popularity of those big boxy soft roaders.

I towed sw20 2500 kms to MTC 15 with v6 vs commodore used 21lt per hundred it did not miss a beat. I did put a v8 transcooler and a bigger oil pan for the auto and haymen reece towbar. The thing cost lest than $1000.00. Save your money.

What drugs are you guys on? A diesel will use ALOT less fuel then a petrol under towing conditions. I think an X5 is something like 8.7L/100 combined (not towing obviously). I have a 75 series L/C at the moment and its an old inefficient diesel and when towing my car still uses far less then 21L/100 towing my old exige on trailer. I could see an x5 doing 14l/100 towing my race car no worries. Also, whats towing capacity and ball weight capacity on your commodores?

For the amount of towing I do which is not much. I'm not going to spend thousands on a 4x4 desiel to tow a race car. Rather use 21lt per 100 towing by the way. Yes desiel is cheaper to run towing a race car. I would perfer to put my money into the race car. If I had a lots of money I would get a big desiel and I do not have lots of money so the commodore we do for now.

Big truck = good for towing race car. Commodore isn't as good. Agreed.
Percentage of time towing race car compared to total drive time = 1%.
I'd rather drive a commodore in the city than a truck thank you, and it's much cheaper and easier to park and more practical. A mate of mine had a Nissan Patrol and he couldn't believe how much room I had inside my Falcon wagon that I had at the time. It was bigger inside than his Patrol. He had bought the Patrol to tow and to have a lot of space inside. Fail

IMO the best thing about Wakefield is that there is hardly anything to hit if you go off the track!
I showed this to many people at the event already (because I found it so amusing), but this is what happened to the silicon joiner from my turbo outlet while I was going down the main straight during one of the passenger sessions: 
I had the same thing happen to me the first time I took my car to the track, is your joiner near your turbo manifold? After I changed joiners I made a heat shield to protect it from the turbo manifold and haven't had a problem since.

What exactly are you on?? At what point do you think you are above everyone else to judge how people should or should not take their car to a event? If you have nothing constructive to add to this thread about MTC, do not comment as no one appreciates it.

Impressive little hole Rob. Equally impressed at how reliable the car was and your driving has stepped up a lot in the last 12 months.

Yeah, most people around here are alot more sensible than me. I should have invested the money so I don't have to work until I am 70! You obviously have a fair bit of BMW experience. How do you rate X5's, around 2005-2007 sort of vintage, 3L turbo diesel.
I asked my BMW mechanic about this a while back when I was looking to get one, he says they are great cars but the biggest problem he has to fix with them is the transmissions. It cost several thousand when they go and he said they do tend to have problems. He's done a lot to transmission jobs on them. Engines are solid.
