Anyone know how long before an '08 tc will have to smog again?

lmao

[ac3 b00gi3]

lmao
i wouldn't have the slightest idea

Register your ride out-of-state with a more off-road friendly attitude. It is hard to believe that Cali is so big on performance and racing but so staunch on being CARB compliant.

come do it in tennessee we have no smog regs or anything : )

Will this affect car insurance?

[beyond305]

will these cams affect the way the vvti acts? our engines are badass DOHC big block 4 cylinders! I wish there was a way to get the vvti to act like the vvtl.....anyone know?

[Soulbane]

It will be interesting to see what the car will be like on a significantly more aggresive cam profile, especially with the VVT-I, but ultimate it depends on the cams that will be available.

The way a staggered cam profile pulls from an even profile is SIGNIFICANTLY different.

[navylife59]

Should be a couple of weeks b4 BC gets there limited run cores instock. Working the angle to get a set made for the TRD S/C. Initially they are going to accept custom grinds. The second run will be only specific grinds according to the company.

[Soulbane]

Hey Navy, did they give any word on the size(s) of the cams?

[navylife59]

The intial run is just 25 sets of blank cores that can be ground to anything that you need. They will be producing a 262/271 lift cams f I remember correctly. Forgot the other specs. You can call and ask for Dustin.

[Soulbane]

Interesting.

A staggered set up.

Probably looking for a more stable and linear power band.

I'm all for 271/271 even profile. I love pulling at the top end. =D

But the staggered cam set up is much more ideal.

okay education time!!!

trying to figure out what this "staggered setup" means. cant wait any longer. what do the numbers mean and whats the difference as far as performance between an even setup and staggered setup?

thanks!

A little reading info to pass the time away.....

My goodness, those links Navy posted is like an automotive textbook online.

Anyways, to get to the point short,

"Staggered" cams means that the Intake cam profile is slightly less aggressive than the Exhaust cam profile. For example, what Navy posted above the 262/271 (I'm going to assume it might've been an error and really is 272) means the profile of the Intake camshaft is set at 262 and the exhaust camshaft at 272.

Staggered cams with the proper tune provides a more stable and linear power availability. Oversizing and making your cam profile "even" at both the Intake and Exhaust side allows for some insane pull at High RPMS, but lacks efficiency at lower RPMS. Not to mention an odd idle.

Read up on those links, they're really informative.


Navy is like the tech guru, I'm just knowledgable about modifications and tech when it comes to the performance of the vehicle. I'm the driver, I let the real brains, like Navy, do all the talking. I just drive.

=D

[navylife59]

Spanks alot. Yeah, I was probably off by one. I used to know a bit about cams many moons ago. Just like most things, I have forgotten them. I believe that the smaller intake profile also takes into account of the VVT-i system. I am going to have to hit the books and come up with the right profile for my setup. I want those bumpsticks to be worth the money.

[TBITB]

those are very informative links! thanks alot, navy. and thanks soulbane for your info as well!

KNOWLEDGE = (horse)POWER (soon! )

[carboncrazytc]

like ive said b4 some guys know wayyy to much lol.

[beyond305]

cant wait to see what these things do to a tc on the dyno! How much hp and tq gains are we lookin at here ? 10 ? Im dieing to unleash the vvti! It has great potential and like navy said, damn bumper stickers need to be worth the money


VVTI and BEYOND!

[Soulbane]

Cams are less about making numbers as they are about unleashing the potential of the vehicle's modifications.

Cams are the perfect, and almost essential modification to any forced induction application.

It broads your vehicle's horizons, it maximizes potential and boosts versatility.

That to me, and to any serious driver, is worth infinitely more than any gained numbers on the dyno.

[TBITB]

so are performance cams made of a different material or reinforced with carbon or something? or are they just bigger and stronger and still made of steel?
