      Thanks man,

      The wedge was no punk though. Made 2560hp with it and found out what parts were weak. Will not have that problem with this motor. But she should put the wedge to shame...

      Oh yeah, I have not pushed those f2's yet either. The b1's would start to surge at about 26lbs. That is something else to factor in. Aw man, I'm all kinds of excited.

      Oh believe me I know....2560 is a serious heavy hitter in every aspect of the words!

      The level of game you are in is not for the faint of heart or bank roll. Some serious stuff going on to play in that arena!

        something to consider...

        top fuel hemi engines they run 6:1 to 7:1 compression ratio venolia's or je's ... there's a reason for that.

        with their supercharger pumping a TON of boost they dont need 10:1's

        even with the 7:1's they run 90% nitromethane / 10% alky. the pistons are coated for the nitromethane

        lots to consider with big boost


        Typical Top Fuel Engine
        Displacement: 496ci
        Block and head: Aluminum Brad Anderson or Alan Johnson
        Bore x stroke: 4.310 x 4.250
        Compression ratio: 7.0:1
        Cylinder head: Hemispherical
        Intake valve: Titanium 2.45 inches
        Exhaust valve: Inconel 1.92 inches
        Rocker ratio: I = 1.73:1, E = 1.53:1
        Camshaft: Mechanical roller
        Duration: 290 to 300 degrees at 0.050
        Roller lifter: 1.6875 inches in diameter
        Valve lift: 0.800
        Supercharger: Roots style, 14:71
        Boost pressure: 65 psi maximum
        Ignition: Twin 44-amp magnetos capable of 50,000 volts
        Ignition timing: 52 to 55 degrees BTDC
        Fuel pump: Mechanical, 100-plus gal/min
        Injection: Mechanical, total of 42 injectors
        Fuel: 90 percent nitromethane, 10 percent methanol
        Oiling system: Wet-sump
        Oil capacity: 12 quarts, 70W oil
        Maximum rpm: 8,250 rpm
        Maximum hp: 8,000 equal to 16 hp per ci

          ^^ what are you getting at?

          There are plenty of people with turboed or pro charged hemis. . I'm sure dj will have this handled.

          HEMI & boost.....they kinda go together. Remember seeing on http://fastmanefi.com/ that Rich had built a 472 pump gas motor with a single Procharger that was over 1250 hp if I remember right, and it idled smooth....

          Thanks for all the info guys. I have 4 year beating on my Wedge that has helped me come up with a good game plan for my Hemi and past and possible future issues have been addressed. Believe me guys when I say, with a little luck, this Hemi will be a contender.

              Those stupid things should be illegal. Stock body cars only is how it should be. If I wanted to watch funny cars race, I'd go see John Force.

              Totally agree, even though the class is "unlimited" I think a good portion of its body should be from a factory car that rolled off an assembly line. Or at least split the class in 2 groups, so guys like Darryl, Larson, Lutz etc aren't going up against the Allen Johnsons of dragweek.

              But what about this one,

              Lutz's new car look factory OEM but it 100% fiberglass and carbon fiber now. You guys know how racers are. You make one rule, they find away around it.

              Machine work finished and heading to the motor man. Hopefully this thing can shorten the gap between my heavy car and those feather lights....

              Same as promod, still not a "real" car. Or to be clearer, originated from a real car. There's hardly enough "real" car left on some of the unlimited cars to argue the point, but I applaud the guys who started with and had to design around an original body.

              Next thing guys will be getting a VIN for nitro funny cars,,,lol.

                Thanks man, and yes, unlimited is getting crazy but I was informed that new rules drop this year after this event. Unlimited is where some changes are to happen so we will see...
