    I like this...reminds me of the twin engine Tiburon from a few years back.

    Keep up the good work!

    Holy **** guys....

    we worked all day on the car. Made some really trick suspension work on the bone stock suspension.
    To completely get rid of the squat while still retaining some suspension and drivability. I can't believe how well it worked.

    60 foot time 1.53 seconds on a dirt covered roads on cold sticky MT tires. (with a burnout on a sticky track it would be 2 tenth quicker no doubt).
    0-60 mph in 2.6 seconds... it's unreal how well behaved it is yet. It is a violent acceleration but at the same time super easy to drive.
    Easy low 10 second car right now on the street with little traction and still running 60% power.
    I'm in love...

    The sad news is by some freak accident the input shaft or chain broke in the rear transmission. It makes no sense as I'm not running a lot of boost at all.
    My parts car with super sticky slicks on a glued track ran 100s of passes with no failure. Blue car 50 passes more HP and no failure either.
    But the only difference is that I start in 1st gear and the 1st to 2nd gear shift is violent. I think that's what breaks the parts.

    All my other drag cars I start in 2nd gear. I don't think it's a coincidence as I ran much more power (150HP more in the red parts car engine) with no failure.

    anyhow we will replace the trans and do 2nd gear starts from now on and see how it goes.
    In the meantime any shop wants to sponsor a transmission job on this car ?
