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.

Make sure you read the terms and conditions and don't let them off the hook
Asurion is counting on the fact that you don't know how to read. They made the claim process aggravating and as difficult as possible. I CAN read and had to review the terms and conditions with them on the phone and threaten to involve an attorney before they would honor the coverage. They tried to say my product was not portable, when the word "portable" is literally in the name of the product. Then they tried to say the the accidental drop was not covered, but it clearly states in the terms and conditions that an accidental drop and a cracked screen is a covered event. I buy the coverage almost every time I am offered it, but I will be rethinking that going forward and Amazon should consider finding a different company to issue the protection plans for their products because I fear this is the beginning of a lot of complaints. I have filed a claim in the past and it was very straightforward and easy, but they must have a new company managing the plans now, because it was anything but easy. If I was an older person who was not tech savy, or who just took someone's word at face value, I would be out the cost of my item and the protection plan. BUYER BEWARE

Love it.
Style: Ink
I love my epson workforce printer. I used to be a Canon person but once I got this printer. It changed my mind. So the ink is worth it. Especially in the bundle package. It may be a bit on the pricey side but it last me awhile. At least, in my opinion, it’s less expensive than buying them separately. Epson makes great stuff and glad I chose to stick with them. The ink is very good and looks great after it prints. Thanks to Epson for functionality, cost and efficiency when it comes you your products.

Epson Ink for the win
Style: Ink
Love my epson printer and that I can order the ink just about anywhere. Ink is of good quality and depending on the amount you print, it seems to last a decent amount of time.

It's ink and it works.
Style: Ink
It's ink and it works. My Epson printer is VERY finicky and only wants name-brand ink. This is it. A little pricey but they all are.
