when to willow springs raceway here in CA and this is the best time i got 12.1sec

 

not bad, at all! what mods?

 

Has to be a stage 1 supercharger. Stock 1/4 mile is like 13.4 I think?

 

i thought that time would be possible with every bolt on, except the supercharger. i guess going from 13.4-8 to 12.1 on an NA engine with just bolt-ons is a bit much. maybe its just wishful thinking on my part because im looking for a b7 wagon and will be doing every bolt on except the charger.

bolt-ons + head package?

 

-JHM tune 91 oct
-2.5" downpipes
-2.5" exhaust with 2.5" x pipe
-JHm TB intake hose
-No spare,no jack,no back seats,1/4 gas tank.

everything else stock form wheels are oem as well 18"

 

very impressive. rear seats and spare must way a ton.

 

to be exact rear seats alone meaning both left and right and bench weight exactly 60lb, spare for me was 40lb (full 18" oem wheel) not a donut, jack and tool box 5lb so lost 105lb exactly.

 

stock 2005 s4 stock form + driver is almost over 3800lb and car does 13.7 -13.9 1/4 mile sounds about right maybe 13.6 with all the right conditions.

 

Also guys forgot to mention this is a 1100 feet sprint little under a 1/4 mile member 1/4 mile is 1320 feet but u add 1.2 sec to ur time and that's your 1/4 mile according to the staff and some of the built muscle cars that are vets there. so i approximately i did 13.2-13.3 back to back to be exact maybe 103-104 mph trap? still fast inmo considering this car is a tank.

 

OOOOohhhhhh, this explains everything. I thought the trap speed seemed a little slow for the time slip. Now it all makes sense.
