    Took My HC for a dyno test today, results are not that bad first run 609whp 612tq second run 637whp 643tq.

    before starting everything my tuner was exploring the car fist HC he saw and we went through the gauges and then he was shocked !!! ho told me your intake is about to be melted it was at 159 that time, sometimes I saw it reaches 161F. So is this normal on all HS's or mine has a problem ? everything seems fine driving,no sound or leaking,and other gauges looks good

    Your temp reading is normal and would not be unusual for most any other car that is not moving though more so with the HC due to all the heat generated by all those horses....long way from melting anything..

    Another thing that just occurred to me, if it was "hot", don't you think that the gauge would be at the high end of it's range???

    That's pretty normal, even for the stock intake. I was getting this with the stock intake sitting in traffic on a hot day.

    Like TNCHARGER and BULL said, nothing to worry about. And yes, these gauges are designed so that when things are at "normal" operating temperature the needles will be "in the middle" of the range. (Zebug...correct also):)

    So you are good.;)

    So I took the cat out today and with this thread in mind, specifically noted my temps and the gauge behavior...

    road speed 45-55mph cruise - no significant throttle...
    Outside temp 45F
    I/C Coolant temp 80F
    Intake temp 100F

    However, the gauge is fast to respond to conditions and essentially went immediately to 161 as soon as I shut the engine off (and the time to scroll to the temp on the dash - less than 4 minutes?)

    So your image here, are you sitting on the road, or are you driving?

    Chances are he didn't have sufficient cooling fans blowing while doing these dyno runs.
    On the road you'd have air blowing all over and directly into the into intake hole keeping things cool.
    If all he had was one of those 4 foot tall floor fans that blow maybe 50 mph winds while doing dyno pulls, that is insufficient.
    Consider, a wide open throttle 4th gear run on the street would have you doing a buck twenty (give or take) at redline.
    He needs the 4 foot floor fan, then a air mover "snail" fan placed 2 feet in front of the intake, and another on the ground in front of the lower grill up as well.
    Then you'd of probably seen cooler intake temps and a bit higher dyno results. However, for a Mustang dyno, which is vastly more accurate then the wildly optimistic Dynojets, your car seems to be in the range it should be:
    714 crank horsepower (as certified by the SAE)
    minus 15-17% drivetrain losses
    = 592 to 607 rwhp.

    I get the same numbers or near while driving so I think we're good, and yeah I wasn't driving the car when I took that picture.
