  2. After selling out of last years red and blue models, Eric Justason has ordered another round of Koozies. The new color options are Blue with Yellow Logo, Red with Black Logo and Yellow with Blue Logo. He is making them available for $1.25 each. You can order yours via his Order Form or you can discuss them in this Thread. All proceeds from Koozie sales go into future SWAG production and event sponsorship.

    Hey guys, I've been trying to find the answer to this question but I have come up short.

    Should I be running premium or regular gas in my 195 HO Impulse?

    Definitely Premium in the heat of the summer, otherwise the engine may protect itself by retarding advance timing (reducing power) if it gets close to the knock border when running Regular.
