With a 12 valve, its almost too easy to build extra power, but sometimes, its the little things that make the upgrades work well together and ensure the longevity of the engine. Upgrading your springs are one of those commonly overlooked, but necessary items.

If you are over 30 pounds of boost or drive pressure, or turning over 3500 RPM with your 12valve, you are experiencing a few negative things. First, valve float, which can cause serious damage to the valvetrain. Second, intake and exhaust valves can be blown open by boost and exhaust drive pressure which allows reversion. Reversion can hurt your power potential by allowing exhaust gasses to enter the cylinder on the intake stroke. Inert gasses in the exhaust, when re-introduced into the cylinder, shield the fuel particles from oxygen in the cylinder. This does a few things that negatively affect power. It increases the time delay from start of injection to start of combustion, it decreases the maximum pressure and maximum temperature reached in the cylinder and it increases the total time needed to completely burn the available fuel.

Correct valve spring pressure is a very important piece of power production. Hamilton has seen 10-12 horsepower increases with customers changing their 60Lb. spring to their beehives. These springs will work well up to 4,500 RPM with moderate cams and OEM size valves. If you are spinning over 4,500RPM with a healthy cam, and/or larger valves, then you need to look at going to Hamilton's dual spring for safety and valve control.

Buy this now!!!
Color: 15- Teal, Size: King (108" X 90")
This is probably one of my favorite purchases from Amazon. I have washed it at least 10 times so far and it still looks the same as when I bought it. It is so soft and snuggly I love it so much. The color is beautiful the furry side is soft and the bottom side has Sherpa on it which is also soft. It's not super heavy and it keeps me warm and it fits my king size bed perfectly. It is such a good value for the money and the quality of it is amazing do yourself a favor and purchase this you will get the best Sleep Quality of your life I swear. I wish I would have had this years ago I don't know what took me so long to find it I have bought several blankets and ended up throwing them away because I did not like the way they felt. This one will be a keeper.

Soft and comfy!
Color: 06- Beige, Size: Throw (50" X 60")
The material is very soft and thick, but not to the point where it makes me feel hot. The only reason why it hasn't received five stars is because I ordered the twin size thinking it would give me good coverage (and I didn't want to order a bigger size), but it's just an inch or two too small for my body. But it's not a big deal. I love the quality too! You will get your money's worth for sure.

Best Blanket Ever!!
Color: 16- Dusty Pink, Size: Twin (60" X 80"), Color: 16- Dusty Pink, Size: Twin (60" X 80")
I am in LOVE with this blanket. I got the dusty Rose, the color is Spot On to the pics. It's perfect size, I bought the twin size. It's reversible, and is Super Soft. Plus, No Shedding. Well made, perfect blanket, it's thick yet but not overly making it perfect for year round. Definitely, worth the money. I sleep great with it. It's so pretty, I love it. Will but again in other colors as well.
