It also takes away rotating mass, it frees up about 10-12 hp and its advertised as something thats good for your engine

Just remember that neutral balance shafts will cause some vibrations.

I think calling it a "delete kit" lead people to a misunderstanding. The shafts are being swapped for different ones and the cost for 10-12 hp seems reasonable.

well if it lessens rotating mass, your motor will be able to accelerate faster meaning faster revving.

The balance shafts in the ECOtec engines are installed to counter the natural vibrations of a 4-cylinder engine to make it run smoother. The negative side is that they are weighted -- thus require horsepower to turn. They are timed/phased with the engine via the timing chain.

Neutral balance shafts are light-weight replacements for the weighted shafts. They require less horsepower to turn (they free-up, rather than create, horsepower). the negative side is that the engine vibration is greater.

If you drive your car 98% of its' life on the street and race it 2% of its' life on the track it probably would not be worth the extra horses to put up with the extra vibration.

What was the price to have the cams and shafts installed? what was the price for them overall? where can I get them? Im excited as hell, because i finally plugged into HPTuners and upped my rev limit to 7K, but im still running stock cams and springs. There is so much power in the top of 2nd and 3rd just by adding that extra 200 rpms! I cant wait to see what better cams and a limit of 8K will do!

never had to tune them in, they work like a charm, but tooning will only make them better, if you have a raised rev limitor you might want to consider valve springs so you dont chance a valve floating, to have cams installed 2 bills.

I am sorry Mike, you may not be a good candidate to ride in my car when she's done, or at least not without a couple of prozac and a Depends on.

I'm not sure if this is a repost but what is the highest that you rev the engine to before you start cracking rockers or messing up springs or what not?
