@stuart38 it'slike 10 mpg

[artcaley]

What engine management system are you using and what software to make adjustments? Nice job . Good Luck with it.

[stuart38]

how many mpg will that car take to run?

[rs200000000000]

thats beautiful is it a n/a engine ?, how much does it weight like 1000k g ?, i know its not as cool as that but im putting a 650 hp ls7 in my 200sx road car

@jeffgooloolieThe Exige is a beautifully balanced car,very light with a good power to weight ratio and steering feel to die for,I have driven one on the road (the original with the round headlights) and 2 on track days one being a supercharged one and I can see where you get your opinions from,BUT WAIT,you have just fitted an LSD,to balance the car and to get more power down without one wheel spinning around uselessly-making it EASIER to oversteer and drive.Sound like an LSD is perfect for you

[micktric]

Yeah right,you know jack about me mate,there is no traction control in my vid on youtube in the IOM-watch it,and I have no traction control on my Harris R1 with 173 bhp at the rear wheel or on my GSXR on the vid-you have completely missed the point,you are proberly one of those people who laughs at someone not being able to drink 15 bottles of bud then throws up after he has had 5.Lets see your video of you driving your 600hp car down a twisty wet road flat out without T/C or shut up.

[jeffgooloolie]

@micktric : Sounds like TC is perfect for you.

[micktric]

@jeffgooloolie where T/C is not so important but on European roads which tend to be twisty narrow,wet an adjustable T/C is a godsend.At goodwood festival of speed I saw a 700hp ultima go up the hill in the rain driven by a top class formula 2 driver and posted a time slower than a FWD 300 hp rallycar! To give you an example you might understand a F22 fighter is almost impossible to fly without computers,it is a better plane with flight aids.A 700hp ultima I say would be a better car with T/C.

[micktric]

@jeffgooloolie or Corvette is an ideal car to turn the T/C off-quick cars especially the Corvette lots of torque and lots of sidways action but when you come to cars like a 700hp Ultima, 599 GTO,Zonda F clubsport you are in a different league when it comes to cornering speed on the road and you will still have opposite lock,smoking tyres and all that but in the 599/Zonda the tyres are keeping there grip on the road more while you get on with the driving.The Ultima is faster on a track -cont

[micktric]

@jeffgooloolie Yeah right thats why formula 1 cars and moto gp bikes have it,look you simplify it to much,you look at cars in a very insular way-typically American,read a review on the new ferrari 599 gto, EVO magazine is a good example,read the review by Chris Harris,that car is almost undrivable on the road without driving aids,it has been designed to be unstable,on the limit of the difference between a road/race car,it actually drives better with driver aids on.You see a Camero -cont
