Valve Recommendations

At this power level, replacing your OEM valves with aftermarket valves is a must! An aftermarket valve is constructed of materials that can withstand the heat. Aftermarket valves bend, OEM valves break.
Is a bigger valve better? Nope, we have made 1800whp with a stock size valve on the quickest and fastest DSM on the planet.
FUN FACT! Oversize valve will flow less than the stock size valve up to .350 lift (9mm). This means that you will lose more than you gain going to oversized valve when using a cam under 10mm lift!!

A common concern when picking out a spring kit is adding too much spring pressure, especially in street applications. When it comes to the spring, more pressure is better than less pressure. Less pressure will result in valve float which can cause damage to your valve-train.
The correct amount of pressure will keep the springs controlled which in turn controls the valves. The number one cause of valve-train and or cam/bucket failure is not having the correct valve spring for your application. If the valve spring is not happy, nothing will be happy.

Are you planning to sit in a lawn chair and listen to your car? If so, purchase the biggest cam on the market and you’ll be a happy camper! The big chop will add happiness to your ears, but it will feel laggy because the camshaft is too big!
If you enjoy beating the crap out of your car and jumping into boost, a smaller cam is the cam for you!
At this power level we suggest no more than 240 degrees of duration @1mm (.040) for up to 1000whp. If you’re making more than 1000whp, try to get a cam with no more than 242 degrees of duration @1mm (.040). This will lead to lots of area under the curve that will keep your dyno happy with miles of smiles.

If you’re making 700whp to 800whp we often get asked if a full port is necessary, the answer is no! A full port has too much port volume and will hurt the area under the curve under 700whp.
If you plan on making more than 850whp and have some room in your budget, our CNC port is the way to go! You will see gains up to 140whp in the mid-range with same peak power and gain faster spool time! It is really a powerhouse with added reliability!
Lucky for you we offer a budget-friendly upgrade, known as the pocket port! It will give you the ability to make more area under the curve and at a lower boost level so you don’t have to push your combo to unsafe boost levels.
