My 07 Chevy impala LZ4 has variable cam timing and that torque is immediate

So glad I seen this video. I was about to do a VVT Delet on my LT5 engine. This made me definitely change my mind. Why are so many people on you tub doing a VVT Delet? Is there any benefit in doing a VVT Delet?

So I did it I installed a VVT engine in my 2004 GMC non vvt truck after driving it for a while the only thing I noticed is I need to dial down the injectors pulse other than that lots of power the computer doesn't know it's supposed to be connected Had to buy lots of adapters but it works didn't want to cut up the wiring harness can be seen on my KZfaq channel

I don't see why not. We'll keep that in mind when we come across one in our upcoming Ford class!

I decided to keep the VVT and stroke the bottom.

My car is tuned already making 90hp more than stock. I did not touch vvt adjustment at all. How do I know what will gain power and is it safe to advance to Max or just like with spark timing there can be knock?

Bring in a pro I'd say. Don't knock a piston if you don't need to

When advancing cam timing you might get into knock as well since you are increasing VE on the same RPM, I'd say if you want to give it a try use good quality knock phones to catch it and pay attention to your AFRs.

I am confused now so if I can advance and retard my vvt cam through the tune like you demonstrated why do people install a cam phaser limiter
@georgeneufeld5031 3 жыл бұрын
If you install a bigger cam you could have piston to valve clearance issues so you can only phase it to a certain point

That's true for spark timing not cam timing

This is so dumb, how about explaining why and not the result. This isn't helping anyone.
