    Spark Plugs for Blown Motor

    I don't know anything about the NGK but the Autolite 3923's gapped pretty tight work well in my centrifugal setup. I think they may be 2 heat ranges colder than stock. Once you find a good plug I'd play around with the gap on the dyno; I gained 40 rwhp just from tightening the gap.

    Drive line loss

    While the amount of driveline loss (power, not percentage) will rise somewhat with increases in power, the truth is that driveline loss is closer to a fixed amount for a given car than it is a fixed percentage of total power. Because it is really neither, and because there is no ready way to...

    Anyone Use An AEM instaed of a VEC 2?

    I don't think there is any may to that one--unless you are a major gearhead to start with and also willing to invest a ton of time in learning how to program the AEM (like Tony), you WILL need a professional tune.

    Anyone Use An AEM instaed of a VEC 2?

    Swapping in the AEM for the stock ECU is plug and play--anyone could do it. However, there is one wrinkle. There is something about the electric door locks and security system that will work only with the stock ECU, so if you want everything to work like stock you have to remount your stock ECU...

    Ferrari? What Ferrari?

    There was a segment on the Today Show a couple of weeks ago showing an Ferrari dealership located in a hotel lobby in Vegas, and the dealer said they had just had their F430 Spyder flown in from Italy a couple of days before and it was the only one in the country. There might be a couple more...

    Do Paxtons have a whine to them?

    Allright you two quit arguing and answer a question for me. My Heffner setup, and I think the stock Paxton setup, uses a spring-loaded tensioner so there is really nothing to tighten. It either has enough tension on it to keep the belt from slipping or it doesn't. How is the DLM setup...

    Vortech Supercharger...

    To my knowledge Heffner hasn't used a Vortech head unit in some time. The Novi 2000 has proven to be hard to beat.

    Will the newer B&B X-pipe rear section work with the earlier non-X catback?

    For the archives and future searchers, I called B&B and the X-pipe rear section will NOT work with their earlier catback system. :(

    canadian viper value

    You'll have to bring it in through a registered importer, and the costs associated with importation are in the $500-$750 range I think. Other than that, go for it. It's the same car made at the same plant, and you can get the plug the U.S. cars have in place of the daytime running light module...

    Thanks to Jason H and my new AEM computer

    One way is to program it to turn on the high-speed fan at say 180 or 185 rather than the stock 210 or whatever it is. It's a lot easier to keep it cooler if you don't let it get so hot in the first place.

    Will the newer B&B X-pipe rear section work with the earlier non-X catback?

    Will the rear X section fit the front portion of their earlier catback system or would you have to buy a whole new catback to get the X? I know several people wondered about this when the X version first came out, but I've never heard whether anyone has tried it or asked B&B about it.

    how many of you are running 65 lb injectors in your car?

    Adam, no 65's but I've got 75's at 45 psi. No sluggishness that I know of.

    hp gains from installing B&B headers?

    If you don't mind my asking, what exactly did this research consist of and what were the results? I'd like to see some flow numbers on B&B and other Viper headers.

    Supercharged Viper Owners, what is your level of excitement when driving

    Re: Supercharged Viper Owners, what is your level of excitement when drivin No way would I want to drive on Pilots with this setup. That would be like driving on ice 24/7. You North Carolina boys are crazy! :shocked:

    Re: Supercharged Viper Owners, what is your level of excitement when drivin Perma grin, I like that. :2tu: It's not trademarked is it? :D That's what I had the first time I broke the drag radials loose at 85 accelerating through 3rd. :eek:

    Blower belt slippage cross post re new Monster Mustang.

    They aren't run on the same belt. The centrifugals use an additional pulley on the crankshaft in front of the stock crank pulley, and the only thing it's running is the blower.

    Can 900whp be had with Roe S/C

    I think Brian's best time was actually 9.27, and IMO you can definitely use a lot more than 600 rwhp on the street.

    BF Goodrich g-Force T/A Drag Radials or Kuhmo V700?

    You can run the BFG's on the street (I do), but as noted they won't corner at anything over slow to moderate speeds, and they cannot be used in the rain. They will hook better in a straight line than the Kumho's though. Just depends on whether you're willing to give up any aggressive cornering...

    Can 900whp be had with Roe S/C

    '03-'04 Cobras use the Eaton M112 Roots-type blower. Quite a few owners have done the swap to a Kenne-Bell Autorotor (as I recall it adds something like 75 rwhp without changing anything else and tons more potential at higher boost).

    Who is ready to go drag racing??????

    I thought Brian's car was getting an AEM too? I'm sure the t/c works better with turbos, but it should help quite a bit with the blower too if set up properly.

    Can 900whp be had with Roe S/C

    Exactly what is cocky about stating facts? And speaking of opinions and experiences, what experience do you have with a supercharged Viper? If the guy doesn't want to run NO2, does it make sense to assume he'll be fine with water/meth, when they have certain significant similarities...

    Can 900whp be had with Roe S/C

    Not w/o some combination of NO2, race gas, or water/meth. Didn't I say that once already?
