Are adjustable cam gears of much benefit with stock cams? Seems like not many people run these and there's not much feedback on them. If you ran these on your car at all let me know your thoughts on them. Might buy them to install with valve springs if the benefits are there.

 

generally speaking, stock cams are set up at the optimal timing from factory. about the only time you will see gain by adjusting cam timing is with aftermarket cams and when you dyno tune to pull every last ounce of power out of your combo. imo, not worth it for a street car.

 

but they are good if your blower wants more rpms, cause you can adjust the powerband to the better half of the rpms...

if you can get them cheap and can tune them in correctly they are a great mod, and then when you get cams you can have all of it together

 

Anyone experienced in this? Power gains & "atered degrees"??
Thought I read somewhere that the Time Attack Cobalt ran with std cam profiles but altered timing...

 

Lol there is seriously no point. .. Ecs if u have the ability to get tuned...

 

Time Attack ran the stock cams with adjustable cam gears.

 

That's what I thought. By adjusting the cam timing you can move the torque/powerband, but searching some info on what the Time Attack balt exactly did on cam timing...
Anybody??

 

Don't forget 42lb injectors too!! lol I love that fact since you told me.

 

John Powell would be the guy to ask

Yep!! You know it

 

area47 did a dyno pull on diff cams and stock ones with adj gears... the dyno shows that stock with adj at hgh rpm was cheaper and same results... search it out
or talk to people with them. stock cams arent back. not great buit not bad either. just need a push in the right direction

 

Needs to be adjusted on the dyno. I would say that they are a must with any non-stock cams, else whats the point (although I also say the same thing about any and all off the shelf cams, there's no point to them they're not designed for your setup). If you get them, pay someone who knows what they're doing to tune them on the dyno.

 

Some of the posts here are funny
So misleading.
Pick them up if you can. Contact Powell for good info

 

adj cam gears would be used if the cam event timing is off. if the event timing is off you can loose hp generaly if you deviate from the specified cam event timing you loose power here is a short on why to degree a cam

Talk to any cam grinder, engine builder, or racer and you’ll find overwhelming agreement that “degreeing-in” a camshaft is a vital step along the route to optimum engine performance. At first that may seem strange because “degreeing-in” a cam pertains to checking the accuracy with which it was manufactured.

The purpose of degreeing a cam is to insure that the cam is phased correctly with the crankshaft, per the cam manufacturers’ specifications. You’re insuring that valve opening and closing events are in accordance with specifications, regardless of the cause. Actual valve opening and closing events are influenced not only by accuracy with which a cam was ground, but also keyway position in the crankshaft, crank timing sprocket, dowel pin hole position in the cam sprocket, and accumulation of machine tolerance also play a major role.

 

All of the above is correct, especially if you buy some aftermarket cams. And I assume the LSJ timing is optimised by GM for optimum use in std engine layout on std Cobalt/Redline use...
But when I deviate from the standard LSJ engine specs. (different blower, big exhaust, higher rpm's, different car use like racing etc.) than the std cam set-up/timing can be altered for the new needs. (f.i. shift torque band to higher rpms; no need for low down torque in a race car.)

I know the cam thread Area put up here, but never read anything specific about altered std cam timing.
