Can you hear vtec kick in?
yes, i can. on my S2000 when you reach about 5500-6000 RPM you can definately feel the vtec “kick in.” its a pretty hard kick too, sometimes if you’re pushing it, you can even hear the tires squeal for a second when it jolts.
Why does the VTEC work at lower RPMs?
The gist is that at lower RPMs smaller cam lobes open and close the valves at shorter intervals for normal operation and at a specified RPM a hydraulic pin engages a larger cam lobe to leave the valves open longer to allow more are to enter the cylinders, allowing for increased performance and better fuel efficiency at higher RPMs.
Is there a VTEC kick on the Honda 7G?
Judging from the dyno plot on the 7G, there isn’t really a VTEC “kick” like there is on some Honda models like the Civic Si. From the torque curve, there is a jump at around 4000 RPM.
What kind of engine mode does VTEC work?
VTEC works to change the engine from 3 valve to 4 valve mode at ~2300rpm.
How does VTEC work on a 4 cylinder Honda Accord?
4 cylinders have no VTEC kick at all. VTEC works to change the engine from 3 valve to 4 valve mode at ~2300rpm. 4 cylinders have no VTEC kick at all. VTEC works to change the engine from 3 valve to 4 valve mode at ~2300rpm.
When to lower the VTEC to high or low?
The determine the best VTEC point perform two dyno runs, one with VTEC set low (e.g. 3000 rpm) and the other run with VTEC set high (e.g. 6500 rpm). Set the VTEC point to the intersection of the high speed cam and the low speed cam. Generally if there is a sudden increase in engine output immediately after the cams switch then lower VTEC.
How can you tell if a Honda Prelude is a VTEC?
If yours is a 2.0, it won’t be a Vtec (no such thing as a Vtech!). Have a look at the VIN number in the engine bay, if it has H22Asomething, then it should be a 2.2 DOHC Vtec, you should also be able to tell by the cam/rocker cover, which will have Vtec on it.
What should the VTEC point be on a car?
Generally the VTEC point will be 5500-5700 rpm on a stock engine, 4500-4800 rpm with intake & exhaust, 3000-3200 rpm for supercharged applications. Aftermarket cams generally require a high VTEC point.
How to determine the best VTEC engagement good or bad?
Lol. How bout an explanation from Hondata themselves? The determine the best VTEC point perform two dyno runs, one with VTEC set low (e.g. 3000 rpm) and the other run with VTEC set high (e.g. 6500 rpm). Set the VTEC point to the intersection of the high speed cam and the low speed cam.
