My car is a 02 z28 with bolt on catback supersocker ram kit , power programer whisper air box and nittos.I just put together a nx wet kit 150 shot. my ? is when I ran the car in Hallsvill sunday I ran a 13.2 on moter and 12.4 at 109 mph on the 150 shot . is that rite or does that sound off. Thanks for any feedback.

 

150 shot and u gained .8? Hmm, it does kinda seem a little off.

Probably would have seen better gains off that 150 shot with all the bolt-ons...i.e headers, cut-out and cat back exhaust...

thats just what i think..

 

i've got a 02 ss with 3500 yank,slp headersw/no cats,underdrive pulleys,full bmr suspension,qa1's(hals) all the wayaroundw/springs,and a 150 nx kit. running the car at the track,i have to get out of it right before it shifts .it hits the rev limiter if i stay in it. i run 12.5 on motor and 11.6 on spray but,i'm getting my tranny rebuilt right now. so the next time i go to the track i hope to be running 11.1-11.2.i have a .9 gain but i have to get out of it so i guess i'm not a very got example to go by.your mph should be alot more. my na mph is 109 and my n20 is 119.
i hope this helps you.

I also think the mph should be higher. Traction determines ET.

 

My car did not spin at all but I had to let off, to shift into 3rd. Thanks for the post I will order hooker long tube 3,000 converter and random tech suspension kit.
