Ok, so if you have a Injen cold air intake and probably a alphawerks header (like my setup) or something close to it, theres a good suggestion i have here, today fiddling around with my tc for about 45 minutes, i pulled the stock axleback off, ok so you figure whats that gonna do? but thats the second most restrictive part of the exhaust, so it makes worth while taking it off

all you need is:
WD40
an impactgun/14 mm sockets
if u dont have a impactgun/14 mm sockets u can use a 14 mm wrench but good luck to you ive learned from doing that ...busted my head open

but so it sounds ricey a bit past 3.2 because of the VVTI kicks in but in the lower rpm range it sounds a bit higher noted than the trd exhaust.

try it out its worth the time

 

I didn't think that VVT-i could "kick in". You are making it sound like the way VTEC kicks in. I was under the impression that VVT-i was constantly being used for optimal power while still getting good gas mileage.

 

it doesn't

 

VVT-i is always active. There is no sound of it "kicking in".

 

Steve, is your TC's transmission Automatic or 5-speed manual?

 

It kicks in when you turn the ignition switch

 

Here it is... it had to be done:



But seriously... why would you just remove the exhaust? That's not ricey, that's trashy. That's what 45 yr old rednecks do to their broken down Dodge pickups.

Are you REALLY noticing that much gain? I mean, I wouldn't think so b/c you said that's the second more restrictive part of the exhaust... well, the MOST restrictive is the S-pipe... which is BEFORE the muffler/axle back system. So the main restriction is before the part you're removing.

 

^^ yup, it was just a matter of time lmao

 

poor guy, like crows to a carcuss!

 

You guys are killing me with the fast-n-furious stuff! That's funny.

 

so, basically this post is saying change your exhaust for more power. that is revolutionary ;)

anyway.


our own personal version of my friend in his prelude.

 

This is the best one!!!

 

 

"That's what 45 yr old rednecks do to their broken down Dodge pickups."

I disagree. I'm 33 years old. My red neck is peeling from sunburn last week. Traded in my '02' Ram w/20's on my tc. And i'm still runing stock exhaust. Although I do have a trailer hitch on it.

 

don't mean to take the thread of the subject.... but while i believe the VVT-i is always working.. something happens at just over 3000rpms.. because it defenently feels like something "KICKS" in.. im not the only one that feels it.. i have been asked about it by other tc owners ... there is defenently something that does happen at just over 3k rpm .........

 

the tC makes most of its torque around that area, so thats what youre feeling.

 

Toyota VVT-i - continuous, mostly inlet but some also exhaust.



Toyota's VVT-i (Variable Valve Timing - Intelligent) has been spreading to more and more of its models, from the tiny Yaris (Vitz) to the Supra. Its mechanism is more or less the same as BMW’s Vanos, it is also a continuously variable design.
However, the word "Integillent" emphasis the clever control program. Not only varies timing according to engine speed, it also consider other conditions such as acceleration, going up hill or down hill.


All the information you need, is here:

Page 3 has Toyota VVT-i

 

sorry but i forgot to say i have a s pipe, and i didnt remove the whole exhaust, just the axle back and yes there is a noticable difference

ok well maybe the vvti doesnt kick in, but my car tends to haul ___ more in the upper rpm range than lower? so go figure

blowing my thread up wasnt the point, things were left out, get over it

 

so if the I in vvt-I helps out in going up hills the real benefit would be tricking it to think its going up hill all the time then you'd get the most power correct?

 

Yep, that's why you only want to install the TRD lowering springs in the back. This will make the computer think you are going up hill all the time ;)
