NOPE! Summit Point, West Virgina. Very good Track!

This is when i lived back in Washington, DC.

But he was told to take them off.....

 

Sounds more like Ricer weight reduction

 

I have a question... What the hell is so special about a B16? What the hell does a VTEC sound like? How can you hear when a VTEC is working/operating? What in the hell is an IVTEC? I"m not trying to be a smart ass, I just don't know rice, since the last time I worked on them was in 1991, when I worked for the Toyota dealership.

 

oooohhhh nooooo not a b16!!????

 

nothing is special about the B16 beside the fact taht its DOHC .....and VTEC can be distinguished by a distinct tone change, and is very noticeable with intake/exh, etc.

and thanks all for the backup, i dont feel the need to prove myself to this jealous kid, it was probably him that i beat or somthing and btw, last time i checked it didnt matter if he had a b18, b16, k20a or anything.....he gave me a dissapproving headshake like i wasnt going to win and i spanked him thanks for your concern tho!

 

So why is everyone always going nuts over the VTEC and B16... you would think it was a JATO rocket or something.
What's IVTEC?

 

i have i-VTEC , its alittle more advanced:

i-VTEC system. Variable valve lift is accomplished by using two rocker arms and different camshaft profiles to change the opening of the valve. The other technology is a computer controlled variable camshaft actuator that can vary a camshaft up to 50 degrees relative to crankshaft angle. Let's look at each in a little more detail.

Varying the camshaft in relation to the crankshaft is done with engine oil pressure acting on an actuator located on the end of the intake camshaft. The computer varies the oil pressure to change the rotation of the camshaft on its drive sprocket. This changes the valve overlap. Valve overlap is the amount of time both the intake and exhaust valves are open at the same time. Retarding the camshaft decreases the amount of overlap, while advancing the camshaft increases overlap.

Valve overlap plays an important part in engine operating characteristics. Very little overlap gives the engine a smooth idle and good slow speed torque, but it hinders high rpm engine performance. A large amount of overlap allows excellent engine breathing at high rpm but causes a rough idle and poor performance at low rpm. By varying the camshaft rotation and amount of overlap, the engine can have excellent performance at both low and high speeds.

Variable valve lift is accomplished by opening the valves with two different rocker arms and camshaft lobes. In the past, Honda operated VTEC engines with three rocker arms: two to open the two intake valves and a third that could be locked to the other two causing them to follow a different camshaft profile. With the new "two rocker" design, only one valve is opened at lower engine speeds. This causes the intake air fuel mixture to swirl, optimizing combustion at lower engine speeds. At a rpm programmed into the engine computer, oil pressure is used to lock the two rocker arms together. Now both valves open together but follow the higher camshaft profile the second rocker arm follows

Increased performance is one advantage of the i-VTEC system. The torque curve is "flatter" and does not exhibit any dips in torque that previous VTEC engines had without variable camshaft timing. Horsepower output is up, but so is fuel economy. Optimizing combustion with high swirl induction makes these engines even more efficient.

Finally, one unnoticed but major advantage of i-VTEC is the reduction in engine emissions. High swirl intake and better combustion allows more precise air-fuel ratio control. This results in substantially reduced emissions

blah blah blah its better

 

You can hear a VTEC. It gets real deep in tone when it kicks in. I guess it almost like a power band on a dirt bike???

haha thats if they have some shitty exhaust.....most GOOD exhausts only make the car louder, not more resonant and buzzy

 

THAT'S what I was looking for... someone to break it down for me.
