1/4 times for RS5 and S5 JHM supercharger

[Nemotwo]

Hi,
I was was looking for the best recorded 1/4 mile times for the RS5 and S5 JHM supercharge kit.. stock 4.2 motor? Jake@JHM

well.... due to ring gap on a NA motor vs forced induction... gotta be mindful of risk. some TVS17whatever and higher, blowers will smoke the cylinder walls = lose compression from pushing the motor WOT.... the JHM vortech kit, stage 1 seems uber safe.... if you have an RS5, wait, soon there may be a SC upgrade from JHM.... allow them time for verification.

Can anyone confirm that these are the best times for the RS5 and S5 4.2 stock motor with JHM supercharger kits ?

11.79 is the best time on Dragy, but I believe a few have beat that time with the JHM headers and all the supporting mods. JHM did that without headers, and the updated tune.

SC RS5 should be mid to high 10’s
