Ok i have a stupid problem here...

I have a fully built 12:1 fully balanced worked block and i fully built head, big P&P and TODA spec B and a lot of sauce.

Everything work fine and run great...pull great and go up easy to 9100rpm.

Tshe problem is...where i my damn vtec crossover...a 5900 it have no change in the sound...EVERYTHING is top notch about the vtec...oil pressure a1, all the sensor is OK, no vtec check engine, its pull hard but not that hard its suppose to be :S

I have a tri-y header with a 2.5" exhaust, test pipe and mugen twin loop muffler...kind of part who keep the engine little quiet but i really dont know why i dont hear the crossover :S


So help me with that stupid problem...anyone is running these camshaft?

 

Has it been tuned?

 

if tuned right..then you will barely hear the cross over. my graph is nice and smooth (vtec set @6500). plus the primary lobes vs. the vtec lobes is only a 1mm diff. unlike most cams out there. so the transition is not that noticeable

 

You don't want your vtec x-over to "crack" "pop" or whatever. What you want a smooth transition. That means you aren't getting a dip in power.

Well said! i bairly hear my vtec crossover it has bc3+ tuned on hondata

 

WTF?? If your vtech doesn't pop like a shotgun, that means you're not going fast.

Yeah, mine used to kick in like NOS before I got her tuned.

 

Mine makes people walking on sidewalks jump when my vtech engages, ***** crazy son!

 

Do you got aftermarket intake? Vtak cracks much louder with an intake

 

Oh you best believe! I've got the "whale *****."

 

The ecu is almost tuned, its tuned for my last setup with 200whp...i got a short ram 3" diameter with a stack.

I was just wondering because, last year i was running CTR cam and the x-over was a shotgun lol

In 2 week the car will be tuned


So with these cam is normal to not have a shotgun under the hood? lol

Have almost the EXACT same setup, and barely hear a X-over point, my tuner was top-notch, and there was no dip in power. If it is tuned well, you should be thankful.

 

lot of sauce is a expression around my area lol, that mean, to have all the bolt on that the motor can have


And i confirm, the vtec kick in


I will give some update after the dyno.

thx guys!
