Mike, you are incorrect.
Stick to what you know about mate, going round corners and things
The thing that determines the acceleration of a vehicle is the torque@wheels versus the weight (discounting aeroydynamics at this stage as thats a seperate issue but is still related to torque@wheels)
torque@wheels is a product of BHP and NOT a product of torque.

Mike, you are COMPLETELY AND TOTALLY wrong, its all about BHP.
Think about what determines torque@wheels and you will find yourself retracting that
quicker than kinga pulled out the wine bottle when she realised her parents might be watching her!
Come on Mike, i KNOW that you have the mental capacity to work out why BHP is so much more important than torque for acceleration without me having to explain it to you like a kid, just sit down and think about it!
Hint: GEARING!!!

Torque @ wheels is a measure of how hard the engine is trying to rotate the wheel, thats what determines how much force is exerted on the car in the first place during acceleration, thats beyond dispute, i assume you agree to that yeah?
Torque @ wheels = torque @ flywheel / gearing
BHP = torque @ flywheel * rpm / 5252
So for any given value of BHP you end up with the same amount of torque@wheels
doesnt matter if its 200bhp@10,000rpm with only 100lbft of torque or 200bhp@5,000rpm with 200lbft of torque, either way its the same resultant torque at the wheels as the 10,000 rpm one has twice the mechanical advantage through the gearbox at any given speed
Very basic stuff that Mike, quite shocked at you not understanding it TBH!

Clearly not

All things equal, like what, being in the same gear at the same speed for two cars with completely different power curves?
Thats like saying "tractors are quicker than motorbikes all things being equal" when asusming that the all things being equal are that both are in a ploughed field towing a trailer full of turnips in 3rd gear doing 800rpm
Mike, your comment about torque was completely and totally incorrect, now just take your like a man and leave the thread to people who actually have some knowledge about accelerating

for you.He having a really GOOD run of being wrong judging by this, in fact if wrongness was an olympic sport he could get us a gold i reckon
(especially after i coach him about grey injectors
)

PassionFord Post Whore!!
still end of the day the cossie would win, may not be by much but still will win if its a true 550 bhp.
400bhp@fly would be more than 300 bhp@wheels on a 2wd car. more like 350bhp@wheels.
