I would like some input based on your experiences. Its the off season and the gears in the brain start thinking. Anyway, when I bought my Z and ran it stock, it posted a 8.73@ 84.6. After installing the SSF 3500 and M/T drag radials it has dropped to a best of 8.29 and most of the time a 8.3x @ 84.5-85mph on 1.80 60's. Tried several different launch methods with a 2K stall and stomp working best. I know there are variables that you guys cannot be aware of, but based on the given info (mph, mods, 60's etc.) does this sound like a reasonable ET. It seems a little slow to me. I have also let several other people drive my car to rule out driver error and the ET's remain the same. Am I just expecting too much? If there is any additional info I can provide for a better analysis, just let me know. Nothun but time here
Thank you !!

8.3x @ 104? Is that an 1/8 mile ET and a 1/4 mph?

I think I was confusing reality(et) and dreamland(mph). Sorry, that has been modified. Kinda hard for ya to help with info like that huh

Our cars are very simular in the mods, mine has blackwing ss lid, K&N, egr mod, custom converter and nittos. Yesterday in good weather 50-60 degree and 30.25 bp my car went a 7.91 at 86.5 on a 1.75 60' but no one has really said whether this is good average or what, my car is full weight with stock 17' wheels. My best pre converter time was 8.45 at 85 on a 1.98 60' in simular weather.

See, this is what I mean. Assuming your car is 98-00 (based on the EGR mod) that means not only are you running approx. .3 better than I am, but your doing it without an ls6 intake. You ran .3 better than I did stock. That a pretty big difference. What gears are you running?

My gears are the stock 3.23,s. One thing you have to remember though is these good passes were in very good weather in the DFW area of Texas which is not far from sea level. Where are you running at and what is the elevation.

The hills of Tennessee I believe, and I know that I should know this better, but I believe we are about 850ft above sea level. I did notice you are getting about 1.5 better MPH than I was, but I didn't think that would make a .4 difference in ET. My best time was in pretty decent air also. Well, as decent as these hills can be!!

you might want to look into getting a handheld tuner or getting your car tuned. the tune will pick you up some hp, but will firm up the shifts and you can change the shift points. a freind of mine with a 01 ss has gone 7.81 @ 86 with the same things you got and a superchips tuner.

Well, at the end of next month I plan on getting, cam-header-TD-hptuners and some cosmetic stuff. Those runs were without the slp air lid, but I know that not really going to make a difference. The shift points are ok, I believe, at least for drag racing. Could use some adjustment on the street though. I dont think TM is causing me a problem, unless its just enough that I can tell it. I would really be interested to delete it though, just to find out. I know I should be running faster, I just simply dont know what is hindering me from getting there. Thank you for your input!

Edit: I might wait before I bolt my cam and stuff on a log a pass or two with tuners to see if I'm getting some KR or TM action.
