Hey guys,
Im a member of my-sei and would normally post on there but the forum seems to be down so il see what you guys think
I have a 1999 V Seicento Sporting Abarth with a 32mm Tb, Magnecor KV85 Leads, K&N Induction kit, JanSpeed Performance exhaust, Port polished giving me 75 BHP done on a rolling road, yet I have an odd flat spot which has only recently appeared....
Il explain what I have done since this appeared, First of all I raced a renault 5 and was very close but after that and holding the revs considerably it has felt abit odd.
The flat spot appears after 4300 rpm so when i flaw it I get my quick acceleration and nice pull in each gear and then when i reach around that RPM the car seems to stop pulling almost like something in the engine slows down and it i a noticible feeling, you can actaully feel it stop while sitting in the car...
I must point out my brakes are bad at the moment doing alot of odd noises like a perminant high pitched noise like you here when you press your brakes sometimes but this is that noise all the time while driving until you press the brakes hard and then the noises vanishes, why I am mentioning this is that the feeling with the flat spot feels like almost someone is just pressing the brakes ever so slightly that it slows the car just fractions but noticible and thats the feeling....
I really am not sure what the problem is... weather it be maybe the pads are rubbing on the disc maybe at higher speeds "doubtful" or that something in my engine has gone funny.
When the engine has been warmed up and the heat out of the heaters is pritty hot it has this flat spot and even 20 mins into a journey the flat spot is still there but eventually it goes away after maybe 25 - 30 mins of driving and feels how it use to be....
Any feedback or input into what this might be would be excellent!
Adam
