cruising at 100 on the motorway. thats so cool in a 1.4... you must be revving that engine to get to 115! do you like watching your petrol gague drain at that speed.....
anyway back on topic.
what you need to do to sort out your speed
problem is
1) while car is off, and brake on. push clutch pedal in and remove the restrictor cable from the back of the clutch. this should make the clutch go in and stay in.
result +10hp
2) i would highly reccoment cleaning your 'heavy' nuts as a did this and it worked a treat for me and made my speed go up around 5-10 MPH.
3) i removed the front breaks as these just added unessasary wieght to the car, i now use the passanger and driver door as 'air brakes'.
4) eat a tin of baked beans, cut a hole around 1.1/2 inches in the bottom of it, (it is advisable to clean the tin out first). fit the newly cut baked beans tin over the end of your exhaust and duck tape in to place. (an easy 5 BHP out of these cars)
also adding vinyl
stickers to the side fo your car adds a few extra BHP.
