    • The world's quickest and fastest four cylinder quattro drag car - AudiBoost member speeding-g60's 1.8T 20V stroker Quattro coupe good for 9.3@153

      Much. Respect. This is the kind of thing AudiBoost is all about. The car here belongs to speeding-g60 and below you will find all that has gone into making one of the most ridiculously impressive 1.8T (the engine is stroked but started as a 1.8T) powered drag cars. Who says a small Audi four banger can't be fast? How about 9.34@153 in the 1/4 mile? Incredibly impressive and more than worthy of respect. The full build list with specifications, videos, dynos, and time slips is below.

      Car was dyno'd earlier in 2012 on Dynojet AWD dyno at 38 psi and medium timing and made 759 AWHP and 554 wtq. July 29th Kevin turned up timing in 3rd and 4th gears by one degree from 7000 to 9500 rpm, and added a couple psi of boost in the same range. The map was called HOLDTHEFON1, appropriately named as that day i went 9.34 @ 153.7 with 1.400 60', and made this car the world record 4cyl Quattro drag car fastest AND quickest. At that time it was also both fastest and quickest Audi in N America PERIOD, but since has kept the ET but slipped back into second place for Trap Speed, again behind the S4 VR6T of Chris Green / USP Motorsports.












      Vbox stats.

      0-60 in 2.3 sec
      60-130 in 4.9 sec
      60' 1.400 sec

      Last run of the year for 2012. Wrong discs too much slip. Still trapping in the 150's


      The best runs of the car to date: 9.34 @ 153.7 and backed up with 9.36 @ 153.8. This day the car went 6 passes in a row with traps from 151.34 to 153.84, only a 2.5 mph spread. worst run was in the semi finals i choked as i was racing a longtime friend and a guy who has all of my respect as he is a great racer at 10.15 @ 152ish.


      Dyno run and showing the boost holding at 38psi.... the pull was 4k rpm to 8500.


      And because i wanted to test the dogbox and no clutch shifting, we did a semi-hard pull on the dyno for four gears. and when i say i make >400 AWHP in first gear on 26 psi, it is because i really know i do


      Respect @speeding-g60

        oh, yeah.

        so, i went to the local fast car chassis guy, he builds Pro-mods, Top Sportsman, funny cars, FED's, 6 second type stuff. and wanted him to back half the car. we chatted about it for a bit, brought the car to him, and i decided not to do it. one of the main reasons was that i was having a hard time finding a reverse rotation live axle rear end. that and i just had the cage certed and it would be a lot of backwards work and down all year anyhow.

        SOOOOOO, i got a new Coupe Quattro shell, gutted it, and it is now being built. i am doing all of the tube work so far, and he tells me what to put and where.

        full chromoly tube chassis car, SFI 25.1, 6.00 to 7.50 cert. should weigh in at right around 2000 pounds all said and done. rear wheel drive. no more messing around.

        the goal is to run 7.80's. with my same 4cyl and a turbo 400. and a bit bigger turbo with nitrous, thinking 76mm to 80mm now that i plan to spray it also.

        http://speeding-g60.com/?page_id=1081

        and every day i do stuff to it, i post about it on this page of my own website.

        thanks!!!!! only live once, and you cant take it with you. i figure if i am going to go i may as well go ALL OUT!!!

        this one, is gonna be tricky too. the rear arches get opened up 6" forward, and the front fenders and hood get stretched 4-4.5" or so. that is going to be interesting. but i got another carbon fiber hood to chop up for that.

        real parts..... gonna start out with a 30 x 13.50 drag radial on a 12" wide wheel. eventually will go up to a 32 x 14 on a 14" wide wheel, or maybe even a 33 x 10.5W on a 15" wide wheel. we are building it to the larger tire size, with 40" wheel tubs.

        yup.

        also, while the car is being built to run the 4 cylinder motor i run now, it is ULTIMATELY being designed to run anything in the future.

        BIG turbo Audi 4.2L 40v V8? ok.
        twin turbo LS motor? sure whatever.
        nitrous Big Block Chevy? ok, coming right up.

        the mid-plate will determine placement of motor, and we will just leave plenty of room to grow (forward) if we need to.

        wait you're saying you're building the car to be able to throw any ole engine in there?

        More rear end work was done today. Also made a part for a funny car called The Gambler and helped with a bagged supercharged hotrod Harley bike.

        Finished off the x-locater and made the drop links for the anti roll bar. So cute they are. It is really nice having a lathe to use. 3/8" rod ends in chromoly tube.

        started the front stuff. got a goodly amount of room in there for future upgrades.... when i run out of fun with the 1.8T i am thinking to toss in a 40v 4.2L V8 Audi motor with either one HUGE turbo (88mm or up) or two smaller twins.... anything is possible.

        but everything is just so. 11.9 degrees caster. -0.1 degrees camber. staggered front setup, with the driver side leading the passenger side by 1".

        speeding-g60 -
        and this is showing the front end being moved 4" or so forward, we will be stretching the carbon fiber hood and front fenders that much to move the wheelbase forward.
      1. speeding-g60's Avatar
        speeding-g60 -
        needed some room for tires. so i stretched the rear wheel arches 4" towards the front. the front end will be stretched completely (hood, fenders, etc ) the same 4".


        done all of this myself with some pretty good guidance from an excellent chassis builder.

        putting 3/4" backing strip in so we have something to weld to. sheared all of these strips. and the complicated section at the body moulding area, i used factory material there and split it .

        as he tacks these spots, he pulls the body work out and then tacks it. to keep its shape and prevent warpage. its not completed yet but it is visually good for clearance. and this is the wheel/tire i will use for the street. 315/60-15 on a 12" wide wheel, aka 30 tall by 13 wide. these are my training wheels so to speak. and YES it will be titled and reg'd and streetable.
