what should be my ET in the 1/4

[n0speedlimit]

i want to know what i should be running in the quarter mile i am still on the stock F1's, and i am at a solid 610 rwhp. thanks in advance!

Don't go until you get new tires. With 610 wheel and likely 710 crank, F1s don't stand a chance, you'll be lucky to get a 12 second pass if this is an M6 car/first time.

Need much more information if you want an accurate estimate. Dyno #s dont really mean much as they vary from dyno to dyno day to day. What are your mods? M6/A6? Stock f1s are going to hold you back some, but they are not as bad at the track as some think. I was able to cut plenty of 1.9xs on them and I'm an m6. How much experience do you have? These are all factors that determine how fast you will run.

i found that out i roasted the tires threw the 60 foot i am also a M6 and i was also trying all the different modes that was my first time on the track with my Z.

my mods are kooks 1 7/8 headers with high flow cats and corsa 3in cat back, CAI (airaid), 2.5 upper pulley, ID850 injectors and a nice tune to bring it all together, it has been on 2 different dynos 1 measured 624 whp and the other 605 whp not that it really matters. also i am a M6 i have been to the track many times although ive only hit the strip 1 time in my Z as in the above reply

I had a similar set up, only I had a 9.55 lower instead of the upper which is just a few more % OD. My best run on that setup in near perfect weather was an 11.232 @ 123 with a 1.62 60' on 20" DRs in 500 DA. Most of the year I was in the 11.4 range. I don't see any cooling mods in your list, so that might hurt ypu on the big end if the car starts pulling timing. So I would say the car should be able to run consistent 11.5s at 121ish, assuming you can cut a 60 in the 1.6-1.7 range. Practice quick no lift shifts and smooth clutch engagement on launch is the key. It's just not mash the gas and go like the A6 guys.

My above estimate does assume you have a decent drag radial.

Not even fair to give you an estimate, as you may fall way short of it based on your lack of experience dragging the car...Your expectation should be low, as their are to many variables that play a roll in the numbers that the skilled drivers make out of these highly modified cars...Just go have fun and build from there, otherwise you'll be disappointed with the result and do something out of order and wreck or damage your car in some manner...So a realistic time from me would be the time it takes to get from launch to the timing light in one piece...

i just ordered NT05R radials, any advice when i run them on the track do i need to easy out of the clutch or just dump it

[nighttowl]

Easy and smooth on the clutch release.

Do not overslip the stock clutch, you will over heat it and you will make alot of noise but not go anywhere. However it is a very good robust clutch for a stock clutch and will recover it you mess up with a cool down.

A smooth controlled quick release is what you want, not a dump or a sidestep. Heat up the tires until they are nice and smokey, start with around a 3200 rpm launch and work up or down from there to see what track will handle. With practice, you should be in the 1.70s. If you had MTs you would be deep in the 1.60s, but from my experience the Nittos don't really grab as hard.

Ohh, and dont forget to No lift shift, it really works well.

Two second clutch release. Feed the throttle in at the same rate the clutch comes out. The Nittos hook fine! I sixty between 1.60-1.64 on my stalled mustang. Air them down to 15 pounds.

New tires are just that "new tires" there is no guarantee at this point that they will improve your time or not...You know the dynamic's of dragging so simply refer back to your past experience and apply the same to this car...As others have stated and you already know a smooth steady clutch release and acceleration are the key to getting a good 60', the rest is up to your shifting ability...So again don't have any great expectation on the number, as it will decrease over time and practice...GL...

I ran my Z down the 1/4 mile track this summer for the first time. I was on worn out road race tires and shook the tires half the track and turned a low 12 run just under 118mph. I may pick up some wheels and drag radials for next Summer and work on my launches as I was cutting a mean 2.3sec. 60' LOL. These cars (modded Z, 6spd std, drag radials) should pull a low 11 with 600+hp and some traction IMO. And under 11 if a person is a good driver.

Funny part is by the calculator my Pro-Tour '67 with only 500hp will be quicker because it's so much lighter. Sorry this site won't let me upload a picture, but the calculator shows a 4,100lb car with 630hp pulling a 10.87 1/4 mile at 123mph.
