Recommend me a cam
Hey guys, debating between a blower and cam for my 2010 GS and leaning towards the cam due to cost. I'm looking for something with almost stock driveability, no bucking/surging, with great hp/tq gains. I've been reading about spins cam, anyone know what kind of gains just the cam and tune would net me? Or any other recommendations on a cam? Currently at 410whp mods are long tubes, intake and tune. Thanks

There are many cams available but the absolute best is one designed and spec for you particular purpose and expectations only costs 40. bucks is what I always do cause been rite the first time is important considering the job involvement.

Call Brian Tooley or someone that can custom design a cam for your needs. They can better explain the trade offs of a stock cam vs. the most extreme and every option in between. For me, I'm running a custom grind boost cam on a boosted setup(mild cam). Specs = 242/250 on a 114 LSA with 650 lift. Power gain was good and it's just before the point where I can get surging and what not but I would not consider it to have driving manners or drive ability as nice as stock. But then again I'm a performance guy and that's why I upgraded it in the first place. To each his own.

Also, if you're looking for stock drive-ability and MPGs then a vortech supercharger would better suite you. I understand you want to do cam only but remember the motor is basically an air pump. more air in and more out = bigger power which is why you see guys that do a heads, cam, intake combo getting great results. The cost of doing those three is similar to the cost of an A&A vortech supercharger kit FYI. In fact, I saw another forum member with a new Vortech Ti kit for sale for like $4k or something in that ball park. These kits come with not only power adders but also some of the supporting mods ie. fuel injectors, boost a pump and radiator. Your call as it's your car, just trying to help!

Yeah ultimately I think a blower would be better for driveability, but will cost me 10k Cdn vs about 3500 for a cam. Also the extra power from a blower isn't really useable on the streets anyways. What's better for engine longevity/reliability? I know with certain cams you have to replace the springs every 20k or so but which one stresses the engine more?

If you shop around you may find a great deal on a slightly used super charger at half the price of new. I have seen some take offs from some newer Z06 at half price or cheaper. As you know a super charger is very well mannered very close to stock, but with a lot more power over the cam package. So you'll have a well mannered car with a bunch of power there when you need it.

To answer your other question; it's all in how extreme you go. An aggressive cam with put more stress on your valvetrain. A supercharger puts stress on your crankshaft and bearings along with added heat. However, if you go conservative with any of these mods your engine will last plenty long and be very reliable. I'm not a big fan of pushing the limit.

Just like anything it depends how it was treated. However, with a blower I would just ensure that the previous owner used a properly sized pulley on it and not something super smaller overspinning the crap out of it. A 3.8" or larger pulley on the smaller blowers is probably about right.

Check out Randy at Ragin Racin, he has some different cams he's spec'd.
I went with the stinger cam. No surge, good with the stock converter, drives great through town, still sounds mean and made good power. 432 hp and 451 tq through stock LS2, stock heads still

But, IF the info I found is correct, it has Comps most aggressive lsk lobe profile which comp says "is hard on valvetrain".

The GT-11 has a mild amount of lift. So it would increase strain on the valvetrain as almost all aftermarket(more aggressive) camshafts will do. It's above .600" of lift so you will want to upgrade the push rods, springs, and timing chain. However, it should have good driveability and make the power you are probably looking for.

Your valve train will thank you if you go with a milder lobe and you can get great results. Aggressive lobes for a driver aren't smart unless you don't mind the extra maintenance of checking and changing springs more often.
There is more to a cam than just the number.

What do you recommend as a max lobe?
