Vtec question

[KA98S10]

I just put exhaust on my gsr and wanted to know why the vtec kicks in twice.. My brother has a type-s and it kicks in all at once, so i dont know if its just a gsr thing.. I'm guessing it did it all along, but i just couldn't hear it before. What happens at 4500 the tone changes just like my brothers does when his vtec kicks in, but at 5800 it changes again and you can really hear it in the intake and exhaust.. I bought this car used awhile back and it had the ls/vtec setup and i just recently changed it back to gsr, so i dont know what it had done to it previously.. Thanks for any help!

secondary vtec y0!

rare twin vtec setup! twin turbo nator

your ears are deceiving you. vtec only "kicks" in once.

the GSRs have a "secondary" hit that is not quite audible as the primary VTEC kick.

It occurs when the "secondary butterflies" open or shut. on GSRs the secondaries open around 4200 an primary "VTEC" kicks at 5800ish. sometimes, you can hear it very slightly.

Also, all vtec motors should have a "second dary hit" if they are tuned right. Usually you have the first audible change when VTEC locks, then, there is a slight pitch change later on in the power band, its rare, but properly tuned NA motors do it. If you search around on Rocket Motorsports message board, he goes in depth with it

VTEC

[IntegraXTR]

secondaries are gay, and the worst part if you disconnect that vacuum line then the car won't run as well, only way around is changing the damn IM out.

[devin]

i want 3 vtec points

[B16a2 Civic]

my vtec is reasonably loud, but i rarely let it get that high with these gas prices, i shift at or around 3500

[IntegraXTR]

I drive like a granny because of the gas, got go from gwinnett to smyrna everyday.

yeah man, it sucks, every once in a while i get it up to about 6 or 7 just to hear it it and feel the lil power i have LIRL

[devin]

yeah i usually shift right at 5000, its way too fuckin expensive to hit vtec. i still do it every now and then

[IntegraXTR]

yeah man, it sucks, every once in a while i get it up to about 6 or 7 just to hear it it and feel the lil power i have LIRL

yeh, I hit the first stage at 4500 and shift every now and then, but then again thats why the secondaries suck balls

[B16a2 Civic]

i never hit vtec around any other " tuners" in columbus, i rather them not know LIRL

j/k kevin

[KA98S10]

lol.. yeah i miss draggin frame!! i'm gonna start saving for a yota or hardbody.

[fromdanorth]

gsr vtec kicks in @ 4500 and at around 5800 the secondary butterflies open there no second vtec just because gsr's are dual stage vtec doesnt mean theres two

[KA98S10]

I though it was the other way around

VERY! well SAID !!

PLAIN AND SIMPLE,most vtech motors have 1 stage of vetech that rips at 5000 rpm,some gsrs have 2 stages of vetech,some people love it,honestly,the 2nd stage aint all dat badass,but its normal dude.I would go back to a ls/vetech bro,the ls crankshaft has more stroke than any vetech moter,including type r's,which means more torqe,the gsr heads have more compression than a ls head,ls/vetech,the best swap,and its cheaper

BWAHAHAHAHAHAH !!! jdmcrx12 = FTL!@!

what the FUCK did you just say??

it's simple

4500 rpms- secondaries open, makes audible pitch change (depending on exhaust)

5800 rpms- VTEC pops, less audible sound engine pitch changes slightly (again depending on exhaust)

[green91]

I believe that the secondaries and fairly quiet and when vtec actually engagages its fairly loud. Thats how every dohc vtec car ive been in was. (gsr)

[Z0_o6]

that's why i said depending on exhaust. i was in my buddie's 99 GSR, with just the muffler unbolted (he was about to put on a new exaust) and that's the way it went. :shrug: who knows it may be different for everybody else
