    First Twin Turbo Gen IV

    I have never seen any Viper make what this Underground Racing TT 08 has put down at the 10-19 psi boost range. These 08's are very impressive and they have made a ton of upgrades. The 08 intake is one of the biggest improvements along with the DBW and VVT it is just a killer set up! Not only...

    First Twin Turbo Gen IV

    The 08 Viper with the TT setup are far superior than the 06 Viper with the TT set up. Heads are MUCH improved as the VVT and the DBW make it very nice! Thanks, Kevin Howeth

    Poor UGR experience. AKA: How UGR f-'d me over

    Here's my last response to you on this subject Joe. I am not one bit ashamed of not exempting you from my agreement with Pro-line, deal with it. You say you apologized about the Blown GTS criticism and then restate it again in this post. You did pass on the dirt and the number of people you...

    Poor UGR experience. AKA: How UGR f-'d me over

    Bud, I talked to you several times on the phone and tried to tell you I couldn't do what you wanted me to do without you sending me your car. You kept trying to get me to change my mind but I simply couldn't do what you wanted. I did stop responding to your requests because it was always the...

    Poor UGR experience. AKA: How UGR f-'d me over

    You passed the dirt that was dug up by that woman through email. That makes you a party to the smear attempt. You snip and snipe routinely on Underground threads. I don't like you or your tactics and decided to not exclude you from my exclusive agreement, that's not playing god, that's...

    Poor UGR experience. AKA: How UGR f-'d me over

    No I don't agree. Joe Dell has made several public and private efforts to discredit me so I am not inclined to except him from my exclusive agreement with Pro-line. I'm not ashamed at all. You and Plum have never been involved is similar activities to my knowledge so I was happy to make an...

    Poor UGR experience. AKA: How UGR f-'d me over

    I'm not to dignify this rant of an unstable personality with a lengthy response but I will put some key facts out there. Yes I have an exclusive deal with Pro-line to build Viper engines. This deal allows Tony Armour to have his personal engines built there now and in the future and all others...

    Anyone know the story on this Viper?

    A friend of mine here in NC bought the car new and had it fabricated by someone other than Underground Racing. He subbed out each part of the build. We did the engine short block and tuned the car with a Vec 2. We had to redo some of the turbo system to get the turbo's high enough to return the...
