Last Stock 1/4 miles Runs

FPenvy

I just want to come down, set a sub-12.80, and go to the bar with my family down there.

Curious, whats your best time?

And what are your whp/tq numbers? Also whats the weight of your Z?

Btw, I'm a complete amateur at 1/4 still, but I think my 60' are quite good and I was happy with my ET for 1st try. I found best way to launch my Z is to feather clutch at top and come on progressively on the gas. Launching from higher RPM or dumping clutch always made my car bog.

The stock sport rubber actually surprised me with grip ability, it hooked up well even when dumping clutch at 4k and would make the car bog.

I know my Z can run faster, considering I can now shift at 7700 and power maxes out between 7200-7500rpm. I shifted at 7500 for my last runs. So I really want to go again.

304whp/245tq and 3250lbs with 7700 redline should be able to get 12.5 fairly easy - that's my next goal for the track.

if you want 12.5 better get drag radials/slicks and go on the best weather you can find. also upgrade diff, flatten out suspension, etc...

I've seen people's stock time be their best times based on adding power but no other upgrades mostly with base model open diffs being a major killer.

my best is 12.89 @ 111 with a 1.95 60' on oem size Michelin PSS tires.

car was full weight (with all packages, nav, and bose) aside from exhaust weight savings and full tank of gas.

my redline is 7900 but I shift before that. our car stops making power around 7200 typically so no reason to go above it. plus at 8000 or more without a dry sump it'll damage the engine or maybe go boom.

Thanks for all that info. I should easily hit 12.5 based on your info. I have no extra weight like yourself, just 3245lbs..

Also, my powerband maxes out over 300whp the entire way from 7200 to 7500. It was a really nice tune I got (thanks AAM) that pushed the entire powerband up. Stock, it did top out around 7k-7200k and dropped. I have no drop until 7500 now, Im sure this will make quite a difference.

I'll post my dyno sometime

Just looked at mine. Same here pretty much, looks to peak ~7300 on mine. But never falls off till after 7500.

So I see a clear reason to shift at 7700 now, that extra bit at top of each gear can account for a nice gain.
