SCCA will mandate we use stock exhaust manifolds this year. To give you some comparison, the C-5 has to replace it's current camshaft with the oringinal cam ran back in 99 and 2000, which will be at about a 40 hp or so loss. So you can see SCCA is after slowing us all down, personally it's a real stupid move I think, and will cost us all more money to get our speed back to able to run with Caddy and Audi's factory efforts, that I don't see slowing down one bit. Supposedly Caddy will have a new 500hp LS2 - 6.0lt, on paper it looks like more hp than that and I think SCCA will put a restrictor in place, we will also have a restrictor smaller than last year, I think, but at least if they miss the boat we can change it out. As of now I think the limited prep may go away, to give us a fair shot at adjusting and engineering our car as every one else does. We are all waiting for some final decissions, so we can get ready for Sebring, which we will be leaving for in 64 days. Hope we can continue to bring pride and enjoyment to the Viper camp this new year. Bob Raub / 3R-Racing
