VVT on the new Camaro - Page 2 - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I would imagine, if one would want to change out a cam for better performance in this new engine, it's going to cost a pretty penny having to recalibrate/reprogram the entire electrical system so as not to effect the VVT. Um...I think I'll keep mine stock.

I recently retired from the Delphi plant in Grand Rapids, Michigan that makes the Cam Phasers. They were first used by GM on the dual overhead cam inline engines, like the L6 engine in the Trail Blazer/Envoy and the L5 engines used in the Colarado/Canyon P.U.'s. They've been using them since 2002 on the L6.

These actually mount on the exhaust cam and vary the timinig between the intake cam and the exhaust cam, optimizing torque, power and emmissions at any given RPM. Pretty slick! It allowed them to eleminate the EGR system.

I have not seen how they do it on a single cam motor, though.

That's the Beauty of the system...I mean you could change out a cam and get a little more performance, but not much, the VVT does it for you.

Dear GM,

If you have to keep the camshaft inside the block, then put two cams inside the block. one for intake, and one for exhaust. then hook up the VVT system to each cam.

thanks.

Think about that... this engine in the camaro could easily get over 30 mpg with 400+HP... amazing!

My current vehicle (2006 Pontiac Vibe) has a VVT-I (Variable Valve Timing with Intelligence) and I'm getting 30-33mpg. But it would be nice to have an extra 265+hp to go along with that great gas mileage…

Well, you buy a Camaro, and you can't go wrong in that department...VVT and Cyllinder Deactivation, plus direct injection in a 400+ hp Car that rumbles like a thunderstorm....

Ahhh...can you tell I'm infatuated with this car?
