EXTRACTOR CUSCO SPIRAL vs HKS 4-1 vs FGK 4-2-1

[TRD.AE92]

i'm using FGK extractor with FGK piping...
respond ok ok lo...best power output range around 3500rpm-6800rpm

your VVT engage period wo...

hah..?? vvt triggered by rpm ka?

hah..?? vvt triggered by rpm ka?

seem like my answering was wrong already. Haha... .. pls correct me master!
Beside i didn't mean by VVT triggered by rpm, VVT are triggered because of inlet manifold pressure is right. It normally can operate in range 1,500 rpm till 7200 rpm but if full throttle at 1st till the end (means VVT was on) the normally best power output will at 3,500 rpm till 6500 rpm.

More detail on the the VVT logic - The VVT comes in three types for the 20 valve. To the best of my knowledge, silvertop 20v's pre May 1993 have the VVT actuate at about 4400rpm. Post May 1993 they seem to work on throttle position and ignore revs.
The blacktops seem to work like this, as described on Club4AG -
1. Starting. When you crank the starter there will be VVT operation until the engine fires up, obviously to allow more air into the engine to allow an easier fire up.
2. Coolant temp. There is absolutely NO VVT operation when the coolant tempt is below 50°C except for that brief moment when you operate the starter. Reason obvious, who want to stress a cold engine.
3. Engine rpm. VVT will operate in any rpm between the range of 1500 and 7200 when the inlet manifold pressure is right. The min and max range can be a little out because I was reading from the car tacho. Trust me they are very close.
4. Engine load/inlet manifold pressure. This seems to be the single most important parameter controling the system. The VVT will NOT operate if the inlet manifold has more than about 5 inches of vacuum (can't get the exact reading because everything happen so fast. It's very close.). This is very close to zero vacuum which is atmospheric and that is about the maximum load the map sensor will read to tell the engine in an NA car. As you can figure out the throttle will usually be in the more than 3/4 position for this to happen.
5. VVT will work without the speed sensor

So, there is 3 types here. It is controlled by our dear stock ECU. Mine is the TPS type. Lolx. Pls shoot me if the above is incorrect.

wong, u look like not happy with the result..so sell to me murah2 your fgk header la and you try another header hehe
