Hi pretty new here but have been reading along for a while and wanted to share the progress I've made with my 8th mile times over the last few months. I race at Houston Motorsports Park occasionally. The first time I raced the best I got was a 9.4 with a trap speed of around 80mph which I think is fairly close to the stock times(lost that slip). Managed to beat a gt350 whit that because of traction issues that night at the track. This time I went out and managed to hook and got an 8.82 against a 370z who got a 8.80. I have 255/45 18s in the rear they are continental dws06 plus. Half gutted cats. A custom cat back, mostly stripped interior(left the front seats dash and carpet) and panel air filters. The 370z had z1 intakes and a cat back. This is the best time I've seen in the eighth from a relatively stock car so I was wondering how other people have done.

 

I have a 2012 G37 with shorter tires, drop in filters and Upper intake swap and this is my result! Looking to do 3.69 gear swap and catback exhaust next

 

I have the car listed in my sig and I pulled on a 6 spd 370z with intake and catback (roll and dig). Dude knew how to shift and launch too
