Hello..

What are the benefits of installing cam gears,Using Aftermarket cams?

Also I already got a set of hks 272's and I searched alot about upgrading the valve springs..Some Say that they are not needed with this cams and other says that anything 272 of above should be using upgraded valve springs.

What is true about this?

also I want to know if there will be more gains if I run cam gears with the HKS cams or I should leave the stock ones..thanks

 

cam gears moves the power band

 

any more inputs?

 

I wouldnt waste my money on cam gears to be honest with you, you will not see really any gains. The main idea of cam gears is just to move the powerband, I guess if you were HARDCORE about time attack or drag racing you could move the powerband into the ideal area for what you were wanting to do. BUT to the average person who goes to the track 5-10 times a year IMO it is not needed. David Buschur doesnt use them on his white RS car and the car has gone 9.0's @ almost 160MPH on the 1/4, also to my knowledge AWD motorsports doesnt use them and they have gone 8.9's

As far as upgrading valve springs, with HKS 272's you do not need it.

I used to have HKS 272's and I probably went 25-30 thousand miles on the stock valve springs and retainers. the only reason I upgraded is because it did a whole new setup.

 

thanks for your input! my questions were answered..Do you know how much HP did you pick after the 272? thanks

 

If I were to use 280/272 instead of 272/272 would Cam Gears make more sense?

 

Nothing.

What determines the necessity of a valvespring upgrade boils down to the lift and lobe profile characteristics of the cam, so saying that anything longer than a certain duration requires a spring upgrade is untrue. Basically, a cam set that requires a spring upgrade will almost always deliver more power potential than a set that is compatible with the factory springs. And further to that point, a cam set that requires a spring upgrade will never deliver its own power potential without a spring upgrade.

In a perfect world, all cams are magically timed to be optimized for whatever application the user dreams. Unfortunately, this world is far from perfect.

I realized a 18whp increase and noticeably faster spool by adjusting the cam timing with a set of HKS 280s on my own car. Cam gears are a tool. A change of cam timing to those lazy HKS cams definitely makes a difference.

 

tuned my cam gears on a set of comp 272's and gained 50hp @8K. this is not typical. these cams were just wayyyy off with the stock gears.

 

i have hks 272 cam/cam gears and brian crower valve springs. man after i put those in w/ a full exhuast/intake/o2housing..i was walking on alot of cars stock turbo and untuned. Before i got tuned i was putting down 360whp

 

Good point ted. I may adjust my tomei's and see what happen?

 

Everyone simply says "All cam gears do is move the powerband" but doesnt actually do anything with gain. Or at least any tuner I've tried to talk to about it.

 

And that belief is absolutely, utterly untrue. That is also saying MIVEC VANOS, etc., don't work, and valve timing doesn't matter.

 

Ted you are starting to be my savior in all the threads I participate in haha. I was planning to get cam-gears from what I had read around with peoples results especially since I went with 280/272 which is a bit unorthodox and some tampering might help but when I talked to a local tuner he said he doesnt see why cam-gears would make a difference besides to move my powerband, so I didnt end up getting any.

 

Keep in mind that the same amount of torque moved higher in the powerband equals increased hp. Changes in cam timing are worthwhile mostly if one is willing to take the time to log the results.

 

I wouldnt get them unless im degreeing the engine
