How Can VVT Make More Power?

Want to know how to make more power with your vehicle's VVT? In this Tech Tuesday, Gerrot Jacobson takes a look at variable valve timing, the old way vs. new way of camshaft timing, and what it all can do for your tune.

This will help so many.....including tuners👍

[@TheTuningSchool]

Glad you think so!

[@ST-cu5tz]

Bravo 👏 very well done and said 👍.

[@johnnieburge4997]

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?

[@charliemccutcheon6030]

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

[@marcocasillas5023]

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 TH-cam channel

Do u guys plan on making a live dyno video, tuning a 2015-2018 s550 mustang?

[@coarsegrind]

I believe the word is guys’s!!!

[@TheTuningSchool]

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

[@alphajagtuning]

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?

[@1ripstunna]

self tuned?

[@alphajagtuning]

@@1ripstunna yes

[@charliemccutcheon6030]

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

[@alphajagtuning]

@@charliemccutcheon6030 we are talking about vvt advance not spark advance

[@ofirbraun3008]

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.

[@traphemi6308]

Ummmm what exhaust is on this car????

[@ST-cu5tz]

I decided to keep the VVT and stroke the bottom.

[@marcocasillas5023]

What happens if you don't connect the wires to the vvt

[@bernardwarr4187]

You well suffer with loose of power in the mid rpm range

[@marcocasillas5023]

Thanks 👍

[@hassanabas1549]

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]

If you install a bigger cam you could have piston to valve clearance issues so you can only phase it to a certain point

[@hassanabas1549]

@@georgeneufeld5031 ok got it

[@chvyeter]

Totally thought advancing the timing makes more hp not tq🤦‍♂️

[@GearHeadSX]

That's true for spark timing not cam timing

[@arifm.1315]

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

[@rayvarnson8976]

Still don't like it.
