Is your big block running hot?  Flowkooler designed a high flow water pump with a CNC machined billet impeller with 16 vanes, integrated shrouding and a reduced casting-to-impeller vane clearance.  It achieves greater flow rates, higher head pressure and a more efficient flow. The impeller color is due to Type II Class II military grade surface coating which protects against corrosive fluids. 

FlowKooler introduced the first hi flow pumps and continues to improve impeller design. Why is increased flow so important to cooling a hot BBC engine? Because it has been proven time and time again that reducing the cycle time between the heat source and the heat sink creates more opportunities to shed heat and drop engine temperatures.

From 0-3,300 RPM…Nothing Beats a FlowKooler!

If you need something warm
Team Name: Lightweight Comforter, Size: Oversized King, Color: Black
Not cooling at all. Very warm 365 days a year (I live in AZ) Use it as an extra layer of fluff on my bed rather then an actual blanket as its to warm for me. Very soft though. Washes well and holds its color. Priced well. Lightweight. Have had for sometime and isnt falling apart.

Color and weight are perfect
Team Name: Lightweight Comforter, Size: King, Color: Sage Green, Team Name: Lightweight Comforter, Size: King, Color: Sage Green
Perfect, lightweight; just what I was looking for. It’s soft and feels nice. Sage Green color is true to the photo. I bought a king for a queen bed, I’m glad I didn’t get the queen because it would have left my mattress visible but I can still see the bed with the king. For the price, it’s okay quality and I’m okay with that.

Lightweight, Cozy, and Affordable!
Team Name: Lightweight Comforter, Size: Queen, Color: Lavender Purple
This comforter is such a great value for the price. It’s lightweight but still warm and cozy, making it perfect for year-round use. The fabric feels soft to the touch, and it fluffs up nicely right out of the package. The queen size fits my bed perfectly and looks great once styled with pillows. It also washes well — I tossed it in the washer and dryer and it came out just as fluffy as before, no clumping or shifting. If you want a comfortable, budget-friendly comforter that looks and feels nice, this is definitely a great pick!
