    Honda K24

    Hoover, what are your thoughts on the Honda K24 for the Noble/Rossion? I noticed someone over on Noble Forums swapped one into an M400.

    They are claiming lower weight, improved fuel economy, lower heat, more reliable, and other miscellaneous benefits.

    What kind of power are they getting?

    Ballpark figure for the K24 swap (including transmission) is $25k, about the same as putting in the AER Ford Duratec.

    I have a friend that was the lead engineer for Comptech.
    A normally aspirated race prepped K24 at 275h looses HP after about 7 weekends. The motors are used for only practice after that. Real Time Racing (races with K24) run new motors for only 2 race weekends.
    Running a turbo which increases dynamic load on an already very stressed motor also increased piston speed which will result in earlier digression, respectively.

    The torque band is very linear, but the power band is very narrow and a very short span of 4XXhp.

    The duratecs came from cars that weigh nearly 3100lbs. vs. the hondas k24 motors come from cars that weigh in at 2750+/-, which is what our race cars with drivers must weigh to meet class rules. Therefore, the advantage from the light weight Noble is better, but not by much. Now add in the turbo, intercooler, down pipe, wastegate etc....the weight savings is a bit less than you think.

    when we made the decision on the HVR engine, it was obvious that we don't have to run an ls9 hard to make tq/hp. It's also small and dead nuts reliable.
    the key is to find a power plant that is balanced between power, cost (unless you like exotic motors or purists) and resale value should one decide to sell.
