So if comparing a 5.1 FD vs A2 cams, which would make more sense to change?
I understand having a higher fd will cause rpm to shoot up faster, so you reach vtec zone faster. Whereas the A2 cams, it lowers the vtec point to 4.5K rpm.
So fd is abt pick-up, cams is about power?
Can I say that changing cams will not cause fc to drop
Cams do not directly change vtec engagement point. They alter the power curve so ur tuner can choose the best engagement point for best power. There is no point in choosing ur vtec too low or too high. Basically, set lowest vtec point. See the power curve. Then set highest vtec point. See curve. Find the intersection. That will be the estimation of thr best vtec point.
Cams changes lift and duration. Thus air flow. Which inturns draw more fuel for combustion. Thus more fc too

My frank feeling....
I tried A2 b4, only day 1 feel a bit more power when change gear at later rpm, day 2 onwards feeling same as stock cams.
A3 will be more diff when Vtec open, feel more power.
Value for $, A3 better. A2 like have or dont have like that.
i regretted changing A2, waste $ on labour, not much feeling,
go straight to A3 and a hondata will be great!
Bro. U never tune after installing a2 right? It's very subtle one. Even after tune, prolly just 15-20 horse.
A3 w/o tuning will feel more by butt dyno cos of the weaker low end and stronger high end. Thus more kick.
Both cams tuned, a2 will win from say 2-4k which is daily drive. A3 will win at higher rpm.
There's a bro with k26 and vtec killer cams. His redline is 11k+. This is because he only make power at higher rpm. But can stock internals take it? U will need forged internals Liao.
Yap, both tuned.
i prefer to drive at higher rev, thats y feel more kick.
agreed with u.
