Hey Tony! Man real sorry to hear about that. Sometimes things don't work out though. Pretty good, in the very slow process of getting my primary under my current s300. About a week from ordering the rest of the stuff I need to get things going! Hopefully it turns out pretty good look on the competition section I have a thread up about plans. I've run three sets of Weston's 7mm valves: a 130cc set, a 70cc set, and the current 100cc set. The 100cc are the best of both the 130cc and 70cc set with less draw backs associated with either of the 130/70cc sets. As far as parts I will probably sell my s400 elbow given I can't use it with the compounds without creating a bunch of other fabrication headaches. Probably sell the s300 intake too given I won't need it when I go from running it as a single to a secondary. Cool deal on the plans, I'll keep checkin in with ya to see how you're making out. In the mean time don't hesitate to drop me a line. Take it easy Tony!
