   hi, in my saxo vts when im driving and it reaches 4,000 RPM it seems to have a little kick to it and accelerates a bit faster is this normal or may it have been cammed? its the only saxo vts i have driven so im not sure help
   would it be worth getting it on the rolling road to find out

   I think they are all like this mate but not too sure.
   Theres one goes about where i live and its not cammed and seems to drive like that.
   Think they go like a mx bike where they have a powerband sort of thing although if its cammed it would be the same.
   Best way to check would be is the idle lumpy at all? And also i read somewhere that if its cammed it would rev round to 7800 rpm and if its not it will only rev to 7200? Dont know how true this is though.

   he revs will go past 7200 if its had the rev limiter lifted , not because its cammed mate .
   
   if you think its cammed , take the rocker covers off and have a look , may be a serial number on the end of the cam or sports cam printed into it etc.

   That sounds completely normal - just the engine 'coming on cam', if you like.

   so where would cams make the difference in power? all round rev range! as previous owner told me my 106 gti was cammed but when i took off rocker covers i couldnt see anything on the cams! but he also said he hadnt yet had it mapped, so when i cruise alongsticking at one speed it feels lumpy through the pedal and doesnt want to sit there when i put my foot down it goes lovely. any other way of telling its cammed guys as i dont wunna purchase a set and find out it was already lol
   
   thanks ryan

    Its just the way a 16v drives.
    
    Theyre not as smooth as an 8v and theyres a noticeable increase in power as revs rise.
    
    16vs are a twin cammed engine and 8vs are a single so they have alot more kick higher up the rev range. 'coming on cam' as leeum said

    take the cam covers off m8, and somewhere on the cam it will say if its a sport cam,
    catcams have cat written on them.
    the vts power band is higher up the rev range than say a vtr, so it feels like it pulls harder as the revs increase, then dies off around 7000.
    where as a sport/fastroad cam tends to peak higher, so when mapped the limit is raised slightly.
    id say urs was normal for a standard vts.

    only way to tell if cammed is to take cam covers off if you dont know car.
