Improved Cams

[wristar]

I read somewhere that uprating your CAMS is a great way to improve your motor.

I don't really know much about them, so what are they and whats the deal with uprating them for improvement?

Thanks

Cams are your camshafts.

They control the valves which let in/out air and gasses, high lift cams, keep the the valves open for longer to allow more oxygen in the cylinders to combust.

Thus creating bigger explosion and more power.

A remap of your ecu is recomended to adjust the fuel accordingly.

Hope this helps.

cams/ camshafts open the valves allowing air/fuel in or exhaust guases out.

uprating cams gives them a longer duration ( time the valves are open) and lift ( distance the valves open) and a few other things along with them.

now if you alow the valves to be open for longer thet will allow more air/fuel in or more exhaust gasses out. the more you can get in/out in the set period of time gives a better burn = more power.

after a certian duration you'l need to get a remap, but you can buy cams that don't need one. although id recomend getting a remap with any uprated cams to see the full potential.

after a certian amount of lift you will need to get grooved pistons to prevent the valves hitting the pistons, but this is only needed with really wild cams.

theres a number of diffrent manufacturers of cams all with diffrent 'grades' of cams

which one you choose is down to personal prefferance/budget



hope that helps :)

EDIT - damn you seph! lol

Science explained above, im running kent hi lift cams, expect to pay around £470 fitted.

[wezaddison]

you can get your current cams reprofiled and fitted for about 300 quid

But reprofile cams only alter the duration, not the lift.

You need to have a longer duration and more lift to make the big improovements.

catcams 708's are popular son give kam racing a bell


mind you what model ya got

saying that its in 16v tuning

[goodsum]

the ones on kam racing are catcam... how do they measure against kent cams? they look cheap as hell tho!

remap gona be 350-400 right? anyone know if u can get it done cheaper than that?
