i wanna know without using a piggyback program is there a way to make your Vtec kick harder...b/c i just swapped my motor for an identical one and my old motor hit way harder?

or do i need a piggyback?

 

Kick harder?

VTEC is on/off. There's no hardness.

 

are you sure your wiring is all correct, and that the VTEC is even hitting? What motor are we talking about?

 

trust me there is a difference between how hard this motor and my old motor are hitting

they were both D16y5's

out of a 2000 HX

You shouldn't feel VTEC hitting hard at all .... your "VTEC" is normal cam operation crossing over from 3-valve operation.

 

so then why would it on my last motor...ITS THE EXACT SAME MOTOR?

could it be that my old one had AM cams or something? would that do the trick...cuz i still have the old motor i just dont wanna tear it apart for no reason

I have no idea. All I know is that VTEC doesn't hit hard at all in HX's. No SOHC vtec hits hard without extensive modification.

 

maybe i need stronger ignition

 

cams make vtec louder also in doc, i just put a zex 105300 in my d16y8 and vtec is more pronouced.

 

i dont really care about it being loud for the most part i just want a stronger kick

 

its never physically gona "kick" it may surge a lil or speed up but u will never feel like if u just shifted a gear or something

You'd notice loss throughout the entire power band if you were having igniton problems, not just in vtec. Stronger ignition is just a waste of money unless your car has a gnarly ******* build and a stand-alone management setup.

 

well my old vtec like when it would kick in 2nd gear it didnt feel like i down shifted but...you could definatley tell i was going faster but now i only feel a tiny boost if you will

 

Vtec is simply a changing of the cam lobes. Maybe this motor is a little tired or your vtec is having problems. Or your cams in your other motor made the difference in cam lobe changing more pronounced.

 

so maybe it is my cams?

 

just get a type s if u want some kick or a gsr stop messing with fuel economy

 

well im selling this car i just wanted to know

 

then stop trying to make ur motor""kick"
leave it alone

 

Yeah, put more aggressive VTEC cams in there...if you have a D16Z6, put in a D15b cam, if you have any B series, throw in a CTR or ITR cam. It'll "kick" harder...doubt you'll notice anything though...I mean you'll notice the overall power change but you won't get jerked into your seat when VTEC kicks in...

where's that .swf or .gif of the dyno sheet and when "Vtakkk" kicks in it shooots off the chart...that's neccessary right about now :-P

 

you're never supposed to feel vtec engaging. im surprised you felt anything out of an hx engine.

 

I have an Apex Gen 1 VAFC. There is an option to determine how "hard" VTEC kicks on/off however I have an SOHC, and side from a much louder "whine" on the engine and a bit less resistance on the pulling of the car, there's really no difference. Added to the fact that, when just to see what happens I changed the settings for how hard it "kicks," and I got a CEL until I returned it to zero on both settings. As others have stated, if you want a "kick" for VTEC, DOHC would yield better results.

EDIT: This is the only way I would be aware of to change the "kick" of VTEC, other than a piggyback, don't have any suggestions

 

"kick" is just a ricers way of saying that he wants to feel more of a torque change.

You can always do that by raising the VTEC point.

Normally VTEC is set so that there is a smooth transition from the lobes. If you raise the set point then you will have an abrupt transition and thus feel the "kick" that you want.

Agreed, and the smooth transition is the way it's supposed to work, it can't be good if VTEC is "kicking" so to speak.

Right, it's not the way to make the most torque "under the curve", but that is not necessary for drag racing as long as VTEC is set after the shift transition rpm. When I tune dyno-butt poeple's cars I usually set the VTEC point a little higher to make the car "feel" fun. Then that way the car is still fast for drag racing (which most people are concerned about) and they can always have the seat of your pants thrill that keeps them happy.

For any other type of racing, it is best to make the most torque at most rpms, mid range especially.

when you say i set the vtec higher do you mean you are using a vtec controller so that it engages earlier?
