Pretty impressive! I'm considering doing heads and maybe an intercooler this time next year depending upon money. I had planned on going the full route - heads, cam , intercooler, pistons, fuel pump and injectors - but my soon-to-be-ex-wife leaving me has put a lot of things on hold...

I just wanted to know if you have had problems with Hennsessey. I know his name has been bannned from some of the Viper forums.

I met John at the Norwalk Viper Nationals last September and he seemed like an OK guy. His reputaion as a supertuner is well deserved and his reputation as a rip-off artist was also well deserved. He has paid back a number of the people that were ripped off, but I don't know if it were all the people that got screwed (but didn't enjoy it) or not. He did have a customer go public with complaints recently over old work paid for but not done and John had a few reasons why he couldn't/wouldn't repay the gentleman, but public pressure on John eventually had him doing the right thing and pay the gentleman back. I've never bought anything from John, but I'd feel a whole lot better about doing it now than a year ago. I think he's really trying to right past wrongs. But there are a number of other supertuners out there that have never had so many negative accusations as John to do business with now. Larry Macedo carries Hennessey products, I think, if you like the product and are uneasy about sending your money to John. I met Larry and was very impressed with the way he does business.

Kenny said it best about Hennessey. I had no problems getting the cam and he set me up with a cam that makes really good power. I plan on getting a system like Kenny has on his car so I wanted a cam that would work well with a supercharger. Like him or not, Hennessey can make power and can make cars perform. He has proven that time and time again. That does not justify any of his past actions, but for him to continue to make past wrongs right, he needs to be in business making money to repay his past customers.
RAM MAN, there was actually another Viper with me that made 720 rwhp and 820 rwtq. We had to get someone to sit in his trunk so he would not spin on the dyno at 110 mph plus. Now that is some serious power.
