I just got off the phone with Spohn, and I wanted to hear your opinions on how much time I should drop with these parts. Here is the information first:

before the supercharger I g-teched 12.9 @ 107 (with LOTS of launching practice)

after the supercharger I g-teched 12.8 @ 117 (with NOOO launching practice)

I have z rated 255/50/16 tires and the only suspension mod I have is sub frame connectors. My question to you all is this:

What time drop could I see if I add lower control arms, relocation brackets, torque arm and 70/30 shocks? on street tires? On drag radials?

What is all of your experience? I am curious to hear. Thanks!

 

i don't know times here, but the mods you listed should REALLY help your car bite on launch.

judging by your MPH you are losing alot of time spinning the tires.

of course we all know that gtech's MPH are off, but the diffrence in MPH really shows a big HP gain that you aren't getting anything out off.

 

I had figured that perhaps at the track I would have run a 104 before and maybe a 114 now ... I still have to tune it and all though.

I was told on street tires I should see 3/10ths of a second difference and with drag radials perhaps 5/10ths. I dunno, but perhaps 3/10ths sounds low?

 

I wouldn't get drag shocks, but the rest of the parts are exactly what you need.

On drag radials, it should be able to run 1.7s 60' times, maybe 1.9 on street tires.
