• 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.

      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

        and i agree they truly sound amazing, but i have been into this motor for quite some time, the past 7 years, and i had no inclination to re-learn an entire new motor and buy everything new (except the turbo, WG, BOV, TB) to start fresh to appeal to the likes of you and your choice.

        build one, lets race, and see what we see. Click here to enlarge
        Respect to different approaches and you have the results to back up your decisions.

        putting the motor back in it to try and make IFO next weekend. have a lot of stuff to try out.

        i got some parts, and made my twin disc clutch into a triple disc setup. we shall see how that works out shortly. i am not certain that it is going to work but i will try it anyways.

        couple pictures.... and the motor with a wire tuck done. gonna be finishing it up and firing it up tomorrow.

        and now the motor is installed, just gotta tidy stuff up. put on oil lines, make a new drain line for the catch can as i lost the other one, put on the boost lines for gauge/ecu/fpr/bov.

        and i made the front airdam solid and supported....

        bent up a piece of SS 3/4" x .049 tubing for a lower support. and yes it is removable so it is not in the way of the RS4 replica bumper i normally run.

        yeah, setting the camera up to do it is easy. the processing takes time. gotta have QuickTime Pro. then it is really easy. open image sequence, set frame rate, and then save as. i use another program to compress it down and convert it to a playable media, like WMV or AVI. WMV had a better final result picture quality wise, than AVI did. but that might have been because i tried the AVI @ 1080p.

        got the coolant system up and going. not too far off now for testing!!!! and the boy was so freakin excited, he was jumpin around like a maniac and slipped, hit his head on the counter top corner, and gave himself a little cut on the back side of his head. he is ok, but man he is a SPAZ sometimes!

        well, i have been doing the 1.8T 20v for a few years before this car, and it made all the sense in the world to me to continue with a platform i was very familiar with and had ALL of the parts to make work. plus i like the challenge Click here to enlarge

        but there wouldnt be many parts that would switch over, from the ECU/harness, injectors, manifold(s), clutch setup, TUNE, etc. i would basically be starting over from scratch if i were to go with the 5 cyl that originally came in the car.

        so i got some new vinyl, and had a chance to weigh it after all the changes. last year, IIRC, it weighed 2650 wet no driver. this year it is 2450 at the truck scale (50 pound increments). so i took it to the dump and weighed in on their scale, 20 pound increments, and 2680 with driver now where it was >2850 previously.

        we are going out tomorrow to test it. turned the power back down to ~760 awhp and only like 36-37 psi. was running 42+ psi and more timing when run 9.34. but with 150-200 pounds lighter, we shall see what we see.

        aligned it today, and got all the little stuff done.

        You got 200 pounds off it... incredible.

        so, this triple disc clutch is quite grippy. and i was trying out the no-lift-shift stuff, not to good end either.

        first pass, got a little bite and it bucked and hopped. there was some damage done i did not realize at that time. we discovered it after 3 passes.

        but the first launch broke the outer driver rear cv, the inner passenger rear cv, and messed up the diff most likely. but we made three passes on it anyhow until we figured that out.

        it ran 11.09 @ 147 in FWD on pass # 3, dragging the broken ass end with it. you can hear the sounds it makes in the video, but not in the car.

        this first run had 4 wheels driving on the burnout, got squirrely fast. the next 3 burnouts were mellow in comparison, no wonder as the rears werent spinning.

        run one blew the AWIC coupler, bent the shift rod, broke stuff.

        run 2, it sorta died mid track, bent the shift rod again, and it ended up blown boost reference line off the ECU. and didnt know it was only a FWD car with damaged ass end.

        third pass i decided to do the regular lift-throttle-to-shift, and made a successful pass. 11.09 @ 147!!!!! FWD sucks haha.
