Last Stock 1/4 miles Runs

I've trapped 110 at another local track. I'm sure both aren't downhill lol.

the track isn't downhill.

all tracks I've been to have a rise at the end to promote braking/slowing of the cars

Sure looks downhill in the video, the tracks over here are slightly uphill as they are ex-WW2 runways, they usually slope downhill in the shutdown so the opposite really.

They are great times for sure, just trying to understand why a stock car can pick up 25-26mph in the second half of the track when my car can only manage 20-22mph. But a google search (high trap speed captitol raceway ) found other drivers having high terminal speeds also

If you look at the drag times tables those terminal speeds are very high compared to everyone else , cant help thinking it must be environmental , or perhaps the air is just really good

I trapped 115mph running 12.8

You should be at least around 110 doing a 12.8, otherwise you're not running a 12.8

My 60' was 1.9 on those runs, stock OEM sport tires with 5k miles on em. I did warm em up and do few burnouts.

Trap speed has nothing to do with time! Lol

Well, I wouldn't say nothing....I mean, it varies, especially between different cars. But if you compare between Z's trap speed could be a rough indication of power.

With 600+ hp you should be able to run 10's uphill lol.

looks like I need to go back down to Maryland because there's no way 35~ less hp and stock rubber beat my best time.

Yeah man this is the best time to go. I'm hoping they don't close the tracks early this year so I can go modded.

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.
