i usalu run in 14.6 14.7s on the 1/4 on real tar, and in 15" rims; that WE i hazd my new hartge 16" and crap tires ( maxis mase in korea looool)
the time on the Gtech where always exactly 0.10 to 0.15 faster than the time i did on the track
good news 
a few pics :
the poor vw had a 2L block , Eaton comp , and a standalon,e injection sys, only managed 14.7 a tbest and a even managed to beat him to the 1/8 mile , and only was 1 car behind at 1/4mile
so as you can szee the track was not flat at all ; so i'm really happy with the times i did...i used to run 15.5 and 15.45 on the track last year.
and the time of my freinds in 325i 's :
325i full stock , 323isport gearbox and 3.73 rear diff ( 200km/h max in the config. ) best 15.68s in 195/50/1515.7 regular
325is a little more fuel pressure, and 195 50 15 , 3.91 40% LSD fully emptied ; 15.7 15.9 regular...
complete wreck , totaly eaten by the rust
325ix full stock 195 /50 /15 : 16.1s
325ix ecu moded 195/ 50/ 15 : 15.9s
the fstest 325is was owned by a freinds sister ,sory no pics
;; but my freind car is this 100% original B7 turbo alpina 260 in 4 , puts 5th in loool 
sorry tthe clutch died on the runs so no times available , but it deserves the pics
and sory for the VW but my freind deserves the place , for his 10sec Golf 2 , yes 10.9 sec to the 1/4 mile ,; 4wd 450ch 1L8Turbo ..it just beat the crap out of a 500hp MK4 supra on the motorway ....
ps : the m3 e36 3l and 3l2 only ran in 14.5 14.3 , and only one M3 3L managed 13.9 but he had a totally emptied car , run tires, and a highly expensif moded block ... so not really a 3L.....and so sadly no E30 M3 to take out
not that we really needded it but its not a bad security ;)
