I've done 400 miles in my ibiza cupra and although i have been using full throttle I've always changed gear below 4,000 revs. However, having just looked at the manual it says don't use full throttle for the first 600 miles!

The car doesn't feel that quick and there isn't a strong surge forward when accelerating as I remember which I test drove one.

Could it be that I've done some damage, or does it take some time for the engine to loosen up?

:cheers:

it'll take a 1000 miles before it loosens up really ,most say it doesn't really loosen up til 5000 or more

dont panic , just treat her nicely and she'll be fine

Answer me this oh mighty parts man - though you might know (and the rest of you with Ibiza Cupra's!)

The official figure for max torque on the Beezer is 155ish at 1800 revs....now it doesn't feel like that....

I know that the turbo starts spinning from almost zero revs cos you can hear the whine....(I admit that the nature of a turbo procludes any kind of noticable boost at low revs)....I seem to get the proper turbo effect at about 4000 revs....so how can the car develop it's max torque so far down?

I dunno...perhaps another beer would explain all....

Still tight as flapper said. 1000miles min to settle things down.. The 4K power surge does sound like someone elses motor on here, and that turned out to be a faulty DV(dump valve)-cured by fitting a Forge one. Give it at least 1000 miles before worrying too much.
What fuel are you running? Optimax does work very well in my 210 Ibiza.

torque

torque, in physics, that which tends to change the rate of rotation of a body; also called the moment of force. The torque produced by rotating parts of an electric motor or internal-combustion engine is often used as a measure of its ability to do useful work. The magnitude of the torque acting on a body is equal to the product of the force acting on the body and the distance from its point of application to the axis around which the body is free to rotate. Only the component of the force lying in the plane of rotation and perpendicular to the radius from the axis of rotation to the point of application contributes to the torque. This radius is called the moment arm, or lever arm. The net torque acting on a body is always equal to the product of the body's moment of inertia about its axis of rotation and its observed angular acceleration. If a body undergoes no angular acceleration, there is no net torque acting on it. Units of torque are units of force multiplied by units of distance, e.g., newton-meters, dyne-centimeters, and foot-pounds (or pound-feet).

To compliment flappers lesson one:
bhp=(torque x rpm)/5252

So, If the upsolute upgrade produces 221 Lbft of torque and the engine revs to 7000 rpm (they increase the rev limiter), does that mean that the BHP it produces should be 295 BHP :D , cool :D :D

If it pulls 221lb/ft at 7000rpm then yes. - but it wont be.:)
Where's that nitrous bottle???? :)

not sure what rpm it does that torque at, i will find out on wednesday cos thats when i get my upsolute upgrade:)

I am getting a power map printout with the upgrade so i will be able to find out then

Make sure the bhp and torque graphs cross at 5252rpm else its made up.
