    Default Making progress!

    Took the bird up for a track rental yesterday and had a great day. Other than some heat issues and belts slipping the car ran great.
    This is my daily driver and its set up for long,fast expressway drives, not the track by any means! On the scales the car without me was 3288lbs and Im 300lbs. Car has a stock 97 Explorer gt40p motor with small cam, single 3" exhaust,vortech S trim making 8psi, runs on MS and only has 3.55 gears.

    First pass off the trailer was on the 17s to check some data and get a feel if I got rid of a vibration.
    Walked it off easy with a 2.08 60' 13.13@107 short shifting.

    I tried a few more runs on the 17s but it just got slower since I couldnt go full throttle in first gear without blowin the tires off. I thru on my little 26x8 ET Drags after that.

    I raced my buddies 12 Mustang with a Roush blower and it was closer than I thought for a car rated at 600hp! I pulled a 1.65 12.50@110

    My best pass was against his kids gutted Fairmont with a 347/c4. I ran a 1.65 12.42@110.7

    Left there a happy guy! I think with some skinnies up front,cooler weather and more than a 3000rpm launch I might see a 11.99

    Nice times! You must have put that Bird on a serious diet to get it down to 3288. That's awesome! Just curious, how quickly does the intake cool back down after getting out of the boost? Always wondered about that because I heard the centrifugal blowers don't heat soak like the twin screws.

    lol and I thought it was way heavy for what it is! It has a chromoly K-member, a/c deleted, power antenna deleted, cruise deleted but I added a full sound system with 3 amps,12" sub enclosure ,wiring, the weight of the blower and I was even carrying the aluminum spare with jack and lug wrench!

    Once the blower gets hot its all over, there is no cooling anything down. The lowest my inlet air temps were all day after my first run were 180*. Every pass was 200* and you cant lay a finger on the blower or intake

    Wow! Guess I need to stay naturally aspirated for road racing. Its hard enough keeping a NA engine cool for 20 min above 4k rpm. Thanks for the info!
