Vtec

Looks like i've been owned!

I'm still wondering though why VTEC engages sooo early though??

I think its the VTEC engaging.. i rekon its the pod filter too, ive got a twin 2-1 pod filter and it makes a loud noise @ 3000rom 3500prm, could be a little vtec kick in.

It is the vtec first

Stage 1 (0-4400 RPM): Low-lift cam lobe and long intake runners.

Stage 2 (4400-5800 RPM): High-lift cam lobe and long intake runners.

Stage 3 (5800+ RPM): High-lift cam lobe and short intake runners.

"Most people confuse the opening of the short intake runners as VTEC engagement because of the dramatic change in sound. It is hard to hear VTEC at 4400 RPM using the dual-stage intake manifold because the long runners restrict flow volume to the engine in order to maintain flow velocity."

"VTEC engagement is 4400 rpm, the secondaries open up at 5800 rpm"

they're the fukers that make it sound good :)

if only i had them :(

thanks for the advice... i thought i was going crazy..... :0

is it wise to buy a vtec controller?
since it kick in a lil late?

nothing beats a H22a engine going..bahhhh...mine kicks in 5500 in a prelude VTIR

So the kick that VTEC gives isn't in fact from the cam's switching over, but the intake runners going from long to short?

Is this the same with all variable valve timing/lift cars like MIVEC and VVTi-L?

ahahaha H22a at 5.5k??
mine kicks at 5k.. u can hear it expecially in the exhaust note..*guys who heard my car, correct me if i am wrong :P*

does that make the B18c a diffrent engine compared to others.. with this intake runners and etc..?

Ken

When I drove VTEC prelude kick in was at 5500rpm...
Same with B16C VTEC

With my teggie.......first i hear my AEM V2 make this crazy gushing noise at about 5000 then at 5800 my Apexi GT Spec takes over and i cant hear nothing else after that......

Love driving through tunnels and dropping down to second to really enjoy it....
