There were guys in the early 70s running in the low 12s in air cooled VWs that were driven on the street.... I am not sure that my Fit with a 5 lb boost super charger would have beaten a 66 Beetle that I built up back then in the 1/4 mile, but the VW broke down and needed rebuilding continuesesly. So far my Fit hasn't broken anything
I went to the local dragstrip today and i wondered what are your quarter mile times, with what mods and auto or stick!
I start!!

Stock Power wise!
-19.2 Sec at 71.35 Mph on a sunny Day with 30+°C temp... (Warm Engine!)
-20.2 Sec at 67.90 Mph on the same sunny day with a 150 pounds passenger inside! (Hot Engine!)
-18.7 Sec at 71.20 Mph at night with 20+°C temp with Brake Fluid trap and airbox removed! (Warm engine!)
Removing the filter and top of the air box did reduce 60ft times by an average of .1 - .2 sec but the car also had more top end as the trap speed increased by 1 or 2 Mph!
Marko!!
Ok i went back to the Drag Strip today!!Changes were...-Half a tank of Premium instead of a full tank of Regular...-Fujita SRI instead of Stock Air Box!-Denso IK22 instead of Stockers NGK's!-Tires inflated to 32 pounds instead of 50F - 40R...-AMSoil 0w20 instead of Red Line 5w30...Well the best run i did was 18.23 at 75Mph.... Better still, i let a friend drive the car (He is 40 pounds lighter then me!) and he Managed to do 17.93Sec at 76.7Mph!! Weight really does matters!! Marko!
The MINI Cooper S engine was actually designed by the same team responsible for the Neon SRT-4. It would seem this team is as competent as they are modest. Though only rated at 163 hp at the crank, our MINI cranks out 166 hp at the wheels.

i have a bone stock 09 auto sport and i weighed in at 275 at the time i ran it... 18.1 @ 77 2.5 60'
I returned today with still approx. the same amount of fuel in the tank but i removed the Rear seats, spare tire and even the wipers arms!! I also added NOS Octane booster and it's a shame i didn't monitor Spark advance...
- 17.66 -> 76Mph....
Bizzarely i could'nt go beyond 76Mph no matter what i tried... Increased tires pressure to 50Psi, let my ''70 something pounds lighter then me'' friend drive the car... NADA!! I think the octane rating of the gaz was just too much, and it caused the fuel to burn too slow at the upper revs... It didn't had top end power at all... Granted air temperatures were higher today!! At least, i was able to get the car in the 17's by myself!

I use the NOS octane booster and though I haven't been on a dyno or drag strip have had good results from it..... High temperatures kill my performance even with the super charger.... A !0 degrees difference hurts bad.

What about an Intercooler if you doesn't allready have one?
Thinking about it, i think my times are not that bad at all... There was a guy yesterday with a Greddy supercharged Yaris that did some high 16's runs... Maybe the clutch was slipping... i dunno!!

I am going to try "Run Cool Heat Escape Hood Louvers".... If I was using a turbo, an inter cooler would be a must but I am pretty confident that louvers will make a major difference and if it isn't enough I can resort to the more expensive options preferring methanol/water injection over the I/C.... If my finances will allow, I will be ordering the hood louvers soon and at a later date I hope to be able mount some of their fender louvers for intake into an insulated box surrounding the intake but I will have to use a PRM in the pipe filter but that is going to happen later and only if it is deemed necessary.
