What a great thread ! Have any forum members DMS'd a GT 4.2 ? I seem to remember one guy with a black GT did and spend loads on the car only to sell it a couple of months later??

Interesting points there BB. I suppose what we need to do is put a 4.2 stock against a 4.7 stock and see if the difference is actually that much. Reading between the lines of Maserati power outputs, both Dan and I feel they are low figures and a more realistic figure, using quality fuel is circa 475hp. For one reason or another, more than likely Ferrari, Maserati understate their performance to keep the engine deal sweet. I also feel that this blurring of performance figures is relevant in the 0-60 and more so 0-100 times. The GTS does feel faster that a stock GS, when you plant your foot, the acceleration curve increased...the higher the revs, the greater the pull sensation. Ok this could be a false feeling due to the weight of the thing, but the GTS does go like a surface to air missile!
Then there is Loz with his DMS's GS, lighter, it might beat the pair of us, time for another test me feels.

No we did not, but rolling start both in the same gear, we were neck and neck all the way, the only thing that seemed make one car advance over the other was the curve in the road and the inside track having the shorter distance. I out pulled Dan on the first run, but this was because of the inside lane.

Indeed Frank, I have been harping on about this for years. FIAT produce some brilliant cars but there has always been this pigeon holing in the Alfa/Maserati/Ferrari brands.
Out of the 3 you could argue that Alfa have the best history so it should be round the other way....there's another one for the xmas doo hotel bar!
Ok, there is always the odd portfolio car that will buck the trend (MC/8C) but production wise they follow this rule. Suppose if you are in the market for making money this is the way to do it, but wouldn't it be nice if Alfa/Maserati/Ferrari were all separate companies, competing against each other, that would make for some stunning cars!
Ok in reality we all know that if Fiat had not stepped in they would all have gone, but its a nice pipe dream.
Agree with you Matt that Maserati are likely to understate outputs. Must look on US forums as those guys are forever having dyno days.
As for gearboxes, looking at the very different fuel comsumption and emissions of the two 4.7 engined cars shows how much shorter the MC Shift gear ratios are.
Little nugget for everyone - the 4.7 MC Shift now has an extra 10PS and 20Nm from late 2011 production.

I think that in some ways using HP as an absolute scale is the wrong way to go about things. Horsepower is defined as work done over time. A precise definition of one horsepower is 33,000 lb.ft./minute. IE: if you were to lift 33,000 pounds to a height of one foot over a time period of one minute, the amount of WORK done would be 1 horsepower. A far better figure to use for direct comparison would be torque. HP will only tell you the amount of work being done over a time period, whereas torque will tell you how much "power" you have. To make the comparison more realistic, it's the reason why *** motorcycles always have higher HP outputs than say a Ducati. A typical Ducati will only rev to around 11.5k rpm where a Japponees can rev to over 18k in some instances. so it stands to reason the Japponees is doing more work over the same time period, but this does not mean it has more power.
This was brought home to me when I had my Ducati race bike fettled by Frank Wrathall (Dynojet UK) after an engine rebuild. They had the bike showing 149 hp at the rear wheel before they started, after more than two hours of mapping individual cylinders that figure had increased to 154bhp. However, the torque figure was different story altogether, that increased from low 70's to 95 ilb's/feet. The effect on track was astonishing, the increase in torque meant I could carry a higher gear in most corners. This was most noticeable at Cadwell where I used to take the Old Hairpin in first before short shifting to 2nd for barn with another change to 3rd halfway through the corner. Now I can take the hairpin in second, short shift to 3rd for barn and drive like heck all the way on to the start/finish straight. The trouble is that most folks don;t understand torque in real terms so become somewhat fixated on BHP. don;t get me wrong, you need both, but torque is the true measure.
Dan, could you post the before and after torque figures for your car? They will make much more interesting reading. Still a bloody good thread though, well done you two.

Interesting reading and sensible result - if all it needed was a remap, they'd do it themselves! Think it's need to be a combo of induction, catalysts, exhaust and a remap to get real gains you can feel.
I usually have my cars remapped, usually for 98/99RON (+12bhp in the Aston confirmed from engine designer) but generally to produce a better throttle reponse and increase the torque/power band and lower the peak power slightly. Don't know about you, I rarely do 7k RPM, Britain isn't big enough.
Those cars sounded fabulous by the way

Goes back 30 years or more from my days as a gliding instructor. In the cold weather I used to wear a big woolly hat and grown my beard that bit longer. Got the nickname Yeti and it's stuck ever since. Am on many forums - not pistonheads, and am known as yeti on all of them!

Can anyone find out, what is the closest aftermarket exhaust setup tone for the 4200, that is close to the GTS? Christ, this is awesome!
They do sound awesome, I just love the sound. One of my fav bits is when she first starts up from cold, it makes me smile every time!

But Nikos...you need to be behind the 4200......and they need to accelerate hard to really hear what you exhausts sounds like...whats on yours currently?
Mine burbles away......and can sound quite raucous when putting your foot down, its not as sonorous as the properly set up systems on the GT nor larini...but loud enough for me!!
