    GEARS: 4.10's impressions

    WOW!!!! That is all




    J/K.

    The car feels so much better with these gears . I honestly thought that the Termee was a bit boring ride down the 1320'. Each next gear seems to take forever, where unlike the Mach1 it was a rush from the starting line to the 660' with 4.56 gears! Finally got my chance to run her down the strip and man...she is seriously FUN now!!!!

    Street Driving:
    Reminds me of the Mach1 where one is very busy grabbing gears pretty quickly (2000rpm upshifts). I find myself cruising from Stop Light to Stop Light in 5th gear, so it keeps me pretty active....I call this my work out when I taker her out!

    Freeway Driving:
    Sweet! Cruises just nicely at 2000rpms = 60mph in 6th gear (maybe 1mph off due to the New Nitto DR's). Steep Grades are no longer an issue, where as before I would have to get into 5th gear in some situations that other drivers can present you. The blast from 65mph to 115mph in 4th is super quick! Well, it is a good thing, but a bad thing all wrapped into one. It is like waiting for a roller coaster ride for 2 hours and only to enjoy the blast for not even 6 seconds!!!! <-- estimating.

    Funny thing is that powershifting into 5th gear is EASY!! LOL

    The Good
    Car feels lively and so far no enhanced wheel hop on the street.

    The BAD
    For some strange reason, the Termee's seem to have issues with a driveline vibration. Mine was at 85mph, but after the gear swap, it is now at 75mph!

    ET's?
    I did not get to do a test under the same day and same track conditions. The 3.55 ET was under better air.

    Best 3.55 Gears = 12.274 @ 110mph on a 1.650 60' / BFG DR's

    Best 4.10 Gears = 12.119 @ 113mph on a 1.682 60' / M/T DR's (changed from a 2.90 into a 2.80, idler, FIPK)

    I personally did not see any ET improvements from the 2.80 pulley, but track was getting seriously dangerous, so I had no real way of telling. Prior to the FIPK, car trapped 112mph only...Gears did something good, but not sure how much I can chalk it up too?

    4.10's are NOT for everyone. If you have personal plans to mod up on the HP side, this gear will not be a wise choice. I do not see any future HP mods into this car, then what I already have.

    So, with the new gears, are you doing your burnouts in 2nd gear or 1st ?

    I know LACR is pretty slick and easy in 2nd, but FAMOSO was much tougher, even with the 4.30's in the '01.

    Long as there is water, no issues with burnouts...not that you would know how to do one

    2nd gear burnout...always

    Lou, how much ET did you pick up again? I remember reading it at mod fords, but wasnt sure if it was almost 2/10th?

    It sure makes the car alot more interesting!

    Can't wait to do my gears. Any problems either running or setting up the 3.90's? I'm assuming they are Motive brand?

    I think you are going to hear a little whine with any taller (numerically) gear. The stock 3:55's in my car make a little noise even.

    I was seriously considering 3.90's over 4.10's because I do so much high speed driving. But, besides giving up a little at the dragstrip, I've heard so much bad mojo about non-Ford Racing gear sets from both the installers and owners (though finding an actual owner of that ratio is pretty rare).

    How has you're experience been? What was it that swayed you one way or the other?
