    So if you make 300hp at 6000rpm but can't get it to pull more than 4000rpm in top gear and pushing 25sqft through the air, then your predictions are going to be a little low

    I suspect you will need an honest 325-350rwhp to hit 150mph inside of a mile.


    Andre, that thing can't weigh more than a hundred or 2 pounds more than a GT vert with my fatass inside it. Certainly not enough to make a difference of 200 horsepower!

    So what do you think at that weight Danny(for 130 Club)? You can't go over 139 or you are disqualified. I'm obviously going to be concentrating on suspension anyway, but I'm just not sure if 230 horsepower is going to be enough. I would think it would be. A mile is a LONG way to go at WOT.

      Are you sure you won't need a full cage for a vert?

        You just need a 4 pointer for the 130mph class(and a few other things of course, but that's it as far as the rollbar). I've reviewed the tech sheet. It's really pretty simple, surprisingly.

          LOL @ no rentals. I was originally going to fly into Reno and rent a 2011 GT and head through Nevada on Route 50. Had to rethink that.

          USFRA Sanctioned

          130 MPH Club Rules

          All drivers must be members of USFRA, be a licensed driver, and sign a loss damage waiver to participate.
          A maximum of five (5) runs will be allowed per entry fee paid.
          The 130-mph format is specifically designed for street cars/ motorcycles. To gain entrance into the 130-mph club, the vehicle must run the measured mile twice in the same day at a speed no less than 130 mph. The two runs are then averaged. Once a driver & car combination has achieved 130 club status no more runs will be allowed
          An initial "licensing" pass at no more than 100 mph will be required to calibrate on board speed gauge equipment. i.e.; tachometer, speedometer, etc.
          Maximum speed will be 140 mph - any vehicle exceeding 140 mph will be disqualified from making anymore passes and will not receive a timing slip.
          The driver must wear a Snell 95 approved, full-face helmet, long sleeve shirt or jacket, and long pants.
          Motorcycle riders must have full leathers, which zip together, including boots and gloves.
          Open cars must have a 4-point roll bar. After market roof modifications are considered "open car". Factory only T-tops must have fiberglass or steel inserts in place when running.
          Cars must be equipped with OEM lap and shoulder belts. If vehicle was manufactured prior to belts, they will be added.
          Only gasoline, propane, or natural gas fuels may be used - NO nitrous, alcohol or nitro-fueled vehicles will be allowed.
          Cars must have an adequate battery tie down.
          Drive line loops are required in the front 25% of each section of drive shaft on rear-wheel cars where adequate retention and control of a broken driveline is not assured by body/frame design.
          Dual throttle return springs are recommended.
          Vehicles must have H, V, or Z rated tires which are rated for speeds in excess of 130 mph.
          Tires & wheels for all vehicles will have metal valve caps (metal valve stems highly recommended) & crack-free valve stems. No tires wider than 10" will be allowed, unless the tires are OEM to the vehicle. (Narrow tires work better on the Salt).
          Wheel covers will be positively attached or removed.
          All cars will have a small fire extinguisher securely mounted inside the vehicle.
          A ground cover must be used under the vehicle in the pit area. Waste fluids will not be "dumped" they will be taken off the salt for disposal. Pit areas and general Salt will be kept neat and clean at all times
          Rental Cars will not be allowed.
          INSPECTION:
          -All vehicles must be currently licensed and street legal in their respective state.
          -Fees will not be charged for an inspection.
          -Inspection will verify the acceptable condition of the engine, drive train, wheels, tires, fuel, steering, braking, and safety systems to an approved checklist.
          -Decisions of the inspector are final in the areas of safety assessment and requirements.

                So what do you think at that weight Danny(for 130 Club)? You can't go over 139 or you are disqualified.

                Well, you figure the first quarter-mile will take you about 15 seconds, but you're moving at 100mph and still accelerating. So the next quarter-mile is around 7 seconds, then 6, then 5. That's about 30-35 seconds of acceleration from a dead stop, which really isn't a lot. Of course I pulled every one of those numbers out of my ass, but IMO a stocker '99 GT won't get to 139 in that amount of time.
                When the government pays, the government controls.

                  Got a guess, for shits'n'grins? As long as I hit the 130, I really don't care. I figure I'll probably get addicted after the first time, then the following year I'll end up putting more parts together to go after the 150 club.

                        I'm pretty sure mine will do at least 128.... I'll hold steady at the 1/2, 3/4 and mile marker! LOL! Of course, if I don't shift into OD, then that's about all it'll do!

                          Eric, don't forget that through the auto you're probably seeing more like 215rwhp stock. I don't think you'll see 130 in a mile without more power.
