I'm running AAM intakes without the sleeve so I did a quick street tune to fix the AFR's and get the car running right. The timing still needs to be tuned so I'll be hitting the dyno in the next few weeks to get everything dialed in properly.

The tires are the same one that were on the car when I bought it in June. I'll check to see exactly what they are.

Went to mason dixon dragway yesterday w some friends. Had a blast and didnt do so bad. Im running a fast intentions turbo kit w an ecutek tune on nt555rs 18x11 305/35/18.
These were my best runs. On lower boost settings i was averaging 12.1 with really bad 60ft times. With more practice and some better tires i think i can reach my goal of 10.999 lol
I was in the right lane on these runs.

Just took my '12 370z to the strip at Bradenton Motorsports Park last Thursday for the first time to see what I could get out of my Z. 13.61 was the best I did out of 5 runs (I didn't keep my time slips - I will in the future to get better feedback from you guys.).

I couldn't believe how much better the grip was compared to the street. I can floor it from a dead stop on the street and my back end will be all over the place, holding the brakes to build up RPM isn't even an option. However, on the drag strip, I found that I was actually able to build up RPM at my launch by holding the brakes, with little to no wheelspin. DRASTIC difference in grip as far as I can tell. Anyways, I've got a couple questions about this:

1 - Does it actually help to hold the brakes to build up RPM for a launch, or does it just feel that way? If so, do any of you 7AT guys have any insight on what RPM to launch at?

2 - Is it best to let the 7AT shift on it's own, or is it possible to out-shift the computer by going into 'semi-auto' mode on the 1/4 mile strip?

I'm trying to see what I can change to get a better time out of my 7AT than a 13.6. I have a Mesiterschaft CBE, and K&N Typhoon intake. Stock tires right now, but I have Continental Extreme Contacts coming in later this week, which I hear are lighter than the stock tires so maybe that will help. I removed the spare tire/tools as well for my day at the strip. I was shifting myself, and tried a couple of runs launching at 0 RPM, then I tried a few launching with a little RPM built up, and didn't notice much of a difference - but perhaps I just need to launch at an even higher RPM (like 4-5k maybe?). Thanks in advance for the answers and advice.

Barely launch off idle like around 1200 works best for me in my 7AT G37.

10:23pm on november, 20th. I bet you had some nice sub 50f temps.

Yeah it was cold out like 50* the DA was like -1200. Which is free hp.

I still subscribe to this thread to see how it's going. I like the energy!

NOW you're talking! That MPH will drop you into the tens, BUT you need to get serious. Bold on some drag radials, PLEASE. You can beat me, I know you can.

Your OEM torque converter will limit howhigh your engine will rev. Did you pull a brake fuse to allow it to rev? If not you won't see the gain. I'd try to leave as hard as possible until you GET wheelspin.

Put it in drive and let the computer shift. You might be surprised. I gave up trying to out-think mine, and went quickest.

GREAT consistency. (6) runs within 35 mins, and that late at night?! You were doing laps. A rare privilege.

Keep it up!

Thanks for the info. My 2012 base Z will allow me to rev until the tires break, then it cuts off after maybe 1 revolution. As long as the tires don't break, it lets me rev as high as I want it. I'm the 2nd owner, so maybe this means someone took a fuse out? I'm not sure. Anyways, I guess I'll have to pay attention to what RPM the tires break at on the strip when I'm cleaning the tires before the run, then try to get as close to that RPM as possible during my launch... does that make sense? I'm going back out there tomorrow night so I'll post slips afterwards, just not sure how great it'll look since it's already pushing 90 degrees here in central Florida. With that said, I'm a little curious if my K&N Typhoon is hurting me more than stock intakes would on the strip, considering how long I'm sitting still, waiting to be staged before the run. Florida heat + short ram intakes while waiting to be staged might be hurting a bit more than it does when I'm driving on the street.

I'll also let the auto go and see what it can do for me then, I was looking for someone who has tried it both ways to let me know what works best and you did just that, so thank you very much. I guess I just didn't trust the ECU to allow me to hit just prior to the rev limiter before shifting, but it might actually be better at it than I am - just wasn't sure how 'conservative' the ECU was on shifts even at WOT.

NST pulleys and ART pipes coming this summer, and maybe the motordyne manifold if I can bring myself to sacrifice my fantasy football dues, so looking forward to seeing some progress from this starting point.

The base 18s are too skinny. You need larger wheel/tire combo. Many are selling the sport 19s fairly cheap, slap some PSS or re11 305s with a burnout you can easily dip into the high 12s. Make sure to pull the brake fuse.
My bone stock 370 AT did 12.9 with 285-30-20 all seasons. I brake torqued 300rpm above idle

seanmorr370

I'll add that to my list of parts to pick up this summer, thanks.

I didn't have any issues with grip at launch when I went to the track last week, but maybe that's because I'm not launching at high enough RPM. I'll be sure to pull the brake fuse tomorrow night when I go again, didn't know about that part until just a couple of days ago.

Any input on whether or not I should swap to OEM intakes for the track instead of my K&N SRI? I know it helps with power as long as I've got plenty of air flowing into my intake ducts but waiting to stage in 90 degree heat is probably a whole different ballgame.
