even if you're stock and you have slicks that just grip, you'd see a difference in the 1/4. I noticed lots of people don't consider trying to get the car to hook better with a suspension and better tires after adding power adding parts.

 

Has there been a before and after dyno with the injen intakes yet? On a stock car swapped the same day?

OP, they look great!

 

I've noticed that after you disconnect the battery, the ecu resets, and then my setup pulls hard for about 3 days, then the cars relearns and the power gets soften up. is that normal or all in my head?

 

infinite i think it's all in your head. it's probally that you got used to the intakes already like me and want/need more power.

 

Rkemp1 my mods will soon be intake, headers, hfc, and a cat back then a reflash. i really think il get mid 12's. if not i will get slicks and hopefully get a better time.

 

I need to get my HFC's installed then. I'll reflash after that.

 

I already have all those mods minus the headers and ran on slicks and besides the heat my best run of the night was 13.21. This was on a pretty good run with the exception of an average speed 1-2 shift. 108Nismo and Ex2cinaZ both ran 13.3s as their personal bests and they have your exact modification list. In good weather with a good DA I would say 12.7-12.8 is a more realistic goal. That extra .3 will be alot harder than you would expect to attain. Spray it and you might hit 12.5 or better but NA with the mods your talking about...12.5 aint happening

But I am not a racing god so go prove me wrong...I personally would be very happy to see a bolt on Z run mid 12s. I just wouldnt want to see you get discouraged from unrealistic expectations after your trip to the track nets you mid to low 13s at best.

 

rkemp1 u might be right but il see what happens when i run it.

 

I think high 12's are possible, with all the bolt ons + reflash, slicks and a weight reduction on a day with 65-85* temperature

 

an M3 E92 can go as low as 12.5 with almost 115mph speed... but that car put also ~365 on the ground on a dynojet. a GT3 is faster 12.1 / 12.3 but has a trap speed around 115 too (better tires, lighter and way more take off traction with the engine there).. and same HP to the ground... and those are the best results I found... you do the math on how much power and traction you'll need to hit 12.8 or so.

 

Most definitely man. I wish you luck!
