VTC disabled, what need to becareful on

[wonton]

hi, i think i m rdy to purchase set of cams either

1. toda spec C http://todaracingusa.com/category?se...=2&cid=22&id=3
2. Jun http://www.hipowerracing.com.au/inde...mart&Itemid=57

both require VTC disabled, my question is is that means my vtec will always open? and would tat harm my engine easily (planning to rev till 9000rpm since i will get titanium retainer as well). saw todaracingusa website and it said highly recommend purchase toda piston (another 1k+).

if it's so much problem then i might just go for A3 or lower grade cams...any1 can help me that?

I think VTC for k20 is just the variable timing? VTEC will still come on at where ever it is tuned for the switchover. Vtec killer camshafts are the ones that keep it always on

We use Spec C's in DC5 K20A & retain VTC function & std pistons.
It works well though great care must be taken tuning the VTC.
(too much cam angle can cause pistons to valve contact & or valve to valve contact)
(Std ECU cannot be used as cam angle is too mush & engine damage will occur)
If in doubt, use the VTC killer cam pulleys

the VTC killer cam pulleys= cam gears???

[TODA AU]

Correct. Such as these.

i have been told that even the car can rev to 9000 RPM but still depending on the Dyno curve, if the power max out is 8000 RPM then no point to buy the titanium retainers to let it rev to 9000 RPM...is that correct??

another question if i wan to gain power from 4000-8000+RPM, which cams is better for me? (just purely want feel the 'power')

adding cam gear will let me more easy to tune the car?

For 3000rpm to 9000rpm use Spec C
Peak power is at 8500rpm.
Titanium valve spring retainers are not required.
