    Did you use the standard m400 gear ratios?

    Nope. The gearing changes between the different sized wheels, along with the different drivetrain is all a mixed bag of nuts.

    The gearset I went with is:
    1st - 2.417 (@8000rpm, 58mph with 275/40-17 tires)
    2nd - 1.611 (87mph)
    3rd - 1.263 (111mph)
    4th - 1.000 (140mph)
    5th - 0.852 (165mph)

    I don't do top speed runs, so losing the 22mph from top speed isn't an issue for me.

    Here's me driving around a neighborhood:

    Fuel pump is almost as loud as the gearbox! I haven't had it on the freeway yet.

    Latest dyno on E85.



    Nice gains and the car officially has more power than the Ford V6 it started life with, as well as more torque. The Honda also has more torque under the graph than the Ford.
    Mind you, this engine is still internally stock except for a different oil pump and cam gear. The valves, springs, rods, cams, and pistons are all Honda OEM parts.


    The sequential takes some getting use to, but works fine. It only has 5 gears, but that generally makes it stronger, as the gears can be wider.
    In 5th on the freeway, doing 75mph, I'm at 3800rpms -- not the best highway cruiser. Decent noise, as I have to have my radio up quite loud to overcome the drivetrain noise.


    I also ordered another engine so I can build that up and have a ridiculous engine just waiting to go in.
    I've considering buying some spare gearbox rebuild parts for the dogs and such, just so I have them on hand. The wait from Quaife was painful.

    Played with launch control with the ECU... able to keep the revs at 4000rpm, and make 4psi for a launch. I finally started using it for autocross launches. Will test it at the drag strip later this year.

    Now, if I can get the brakes to be perfect, life would be golden!

    Nice set up, were are you located
    I will stick to my 1800 RPM's at 70 with 350 ft lb of torque at that rpm

    I'm contemplating a Holinger 6 speed sequential 520 ft torque, big bucks

    Engine #2 update.

    Currently having an engine being built, total cost right now is $9000.
    This includes:
    - CP pistons (10:1)
    - Manley turbo tuff rods
    - darton MID sleeves
    - bore, hone, blueprint, and balance block and rotating assembly
    - drag cartel 2.2 camshafts
    - supertech valves, springs, retainers, locks, guides, and seals
    - OEM gaskets and seals
    - new oil pump, cam gear, timing chain, tct, water pump, etc
    - cylinder head valve job

    Engine horsepower goal is for a reliable 600whp-700whp, although the engine should be able to make +900whp.

    I can only imagine what this all would have cost had I had the Ford built to achieve the same power level.

    Another thing that's been bothering me... The fuel feed line from the tank wrapped around the front chassis mount, which is stupid.
    So I pulled the fuel tank out and had the hose barbs replaced with proper fittings, then installed a 180' AN fitting on the lower port to avoid running around the chassis mount. This also reduced the hose line by about 12". The upper port for the return is now a 90' AN fitting, which shortened that line as well.
