Just wondering why my vtec crossover on my 2G JDM B16 with I/H/E and 01' ITR cams isnt as loud as my friends 2G JDM B16 with only I/H and stock cams? What would affect the vtec audible? Im running full 2.25 inch piping with an ES oval muffler. God I wish my crossover was as loud as his. Any ideas?

 

who cares what it sounds like. as long as its working it shouldnt matter

 

Put your stock cams back in your motor along with the stock exhaust (assuming that is what your friend is running). If yours is not as loud as his, then you know something is up.

However, don't you think having the cam + a non-stock, and probably louder, exhaust could make the tone of your VTEC 'quieter' to your ear?

Are you slower than him? Thats the real Q.

 

I've heard that, if you can't really feel your vtec or hear your vtec the better your car is.. what i mean is, it's tuned better and it runs better if you can't really feel or hear the power difference, but it's still there. In other words Vtec is more "flush" with the rest of the power band. Any one, if im wrong correct me, thanks

This may be off-topic, but my gsr motor is more quite in vtec than my friends si. So how can a 1.6 be louder than a 1.8?

The b16 seems to "pop" into vtec where as mine just smoothly crosses over. This is true for every b16 v. gsr motor I have heard.

I have come to the conclusion that maybe since the b16 head flows like an R that maybe it is a bit louder. Mine has more of a deep tone which also may be from a bigger displacement?

Just a guess?

 

Intake exhaust and header can change the sound is there a big diff in the way they feel????

preacherboy is right. VTEC engagement wasn't designed to be extrememly obvious, whether by seat-of-the-pants feeling or audibly. Instead, it's more or less a smooth crossover.

At least that's what's supposed to happen on bone stock, well maintained engines.

 

some vtec are louder than others. my friend sol vtec crossover is really and noticable, while my friend gsr isnt as loud.

 

My vtec kicks me back in my seat quite a bit, but I have my hondata ecu tuned to do so. My dyno readouts show a nice little 'hump' in the powerband as it hits the vtec crossover, which gives it a more sudden transition. I also agree with preacherboy that yours sounds to be a more gradual transition than others. The ITR cams have something to do with it, and after that, TUNING. thats it.

someone who had their hondata tuned CORRECTLY should have no "hump" when vtec engages and no audible kick when it turns on.

you are running off your low lobes too long, thats why there is a hump in power. you are actually hurting performance by having that mad cool vtec kick y0.

 

you tune by looking at the torque curve on the low cam and then the high cam. where they meet is where you set vtec at. this gives you the most area under the graph and increases performance. Vtec should be only slightly felt although the noise will still be very distinct

 

My Friend had a b18c in his crx with itr cams and just a header. When it crossed over to vtec it sounded like an rocket1

I dont know, we will find out on thursday at Irwindale speedway. Ive been wanting to run him since he got the swap.

 

For sure I know my car pulls way harder than his. When his vtec crosses over it feels the same. The only change is the sound of the motor. I just wanted mine to be as audible as his. But Id rather have the power than just the noise.

 

i bet my vtec is lowder than your vtec.....

 

I believe that the feeling/sound of "How hard your VTEC hits" depends on what kind of VTEC solenoid you have. Si were suppopsedly made to be "sportier/racier" than GSRs. The GSR was intentiuonally meant to be a sporty car with many luxuries. So therefore it would all make sense if VTEC engaged more smoothly instead of having that jolting/shoot back into your seat type feeling with Type R engines and B16s. Therefore the sound would be smoother and more gradual also. And yes, I want to switch out my GSR VTEC solenoid for a Spoon one or something

 

nothing is as loud as my sohc vtec ¬_¬

So you're saying that VTEC can only be halfway (for instance) engaged? The only way that would be possible is if some of the VTEC pins were receiving enough oil pressure and others were not. But the VTEC spool won't let the solenoid do its trick until there is enough pressure to do the whole nine yards. I smell poo.

WTF

 

i believe a lot of the v-tec kick comes from after maket parts or combinations. my si didnt have a big kick at crossover. then i put my cai on and then it had more of a kick at crossover. now with the cai and header back exhaust the cross-over is smoother. also cam timing can have a pronounced affect on the crossover. just my experiances i could be wrong.

damn dude relax! I just wanted to know what would cause some engines vtec crossover to be louder than others!

 

IDEALY if you feel VTEC AT ALL then it's turning on WAAAY too late, you want it set low enough you don't feel it turn on w/o having it turn on too early either... VTEC is designed so that you can maintain a flatter powerband all through the curve, that way it doesn't bump... that "bump" that you are so proud of is the part where you're losing power right before vtec turns on, so in reality the whole jerk back into the seat feeling is just that the car was losing acceleration and it gaining it back, rather than maintaining a rock solid acceleration throughout the whole curve. vtec is the all the lag w/o the turbo
