Managed a best of 1.75 60' but time was a 12.2 so still working on the 11's. That was also with my new AGX's on the rear, set at 8 of course, so they do work.

Also managed to lower my N/A time to 14.6 and a 2.209 60' which is nothing to brag about but its good for me. Automatics aren't great off the line at N/A power levels.

Tried out the Nitto 555R's as well for a couple of runs and did a 13.9 @ 101 with a 35 shot. This compares to my street tires where I ran a 15.1 with the same shot and slicks was a 13.1. So they are a good compromise they still leave a lot to be desired.

BTW that was a 350Z in the next lane to me. Must need the professional driver to get the 14.1 they are supposed to do. He did a couple of more runs which were even worse.

PS Yes the calendar was defunct today, clock was right but 6 FEB 2000?, we would be in major snow at that time of the year here.

 

I've been waiting on your post today. 7.7 in the 1/8

 

Nice times. As far as the 350Z they just need to NOT have a ******* driver to get to 14.1. My buddy brian went 13.9 his first time ever at the track with it on a 2.0 60'. Most people just can't drive as you know.

 

Very nice times!

 

Is your car shifting into OD before crossing the line? If it is you'll probably have to goto a bigger slick so you can stay in 3rd. Also if you haven't gotten a 3in exhaust yet, please do it now. At your n2o power level the 2.5in exhaust is choking the engine. What you could do is add an exhaust cutout. They retail for like $20 at summit racing and figure $20-40 for install at a muffler shop. This would allow you to get more exhaust flow once you unbolt the cap.

 

Actually what I am really trying to do it have it hit 6k in O/D when I cross the line, it is now hitting around 5k. I don't want to go to a bigger tire because I lose acceleration, already tried that.

Also tried the cutout thing and again it just makes the car slower. I tried all this stuff last year.

Don't think a 3 inch exhaust will help either if the cutout doesn't work, that would work on a turbo or maybe S/C but nitrous does not require a larger exhaust like they do.

My only problem right now is traction out of the hole and my 2 stage setup will cure that. Even though I have cut a 1.75 60' its still spinning and kicking me up into 2nd too early. So a smaller shot out of the hole and then the 2nd stage after the 1-2 shift should net me an 11.

Alos have a wideband coming so I can tune at the track, auto's are no good on the dyne because they always want to kick down when at WOT and it kicks out the dyno so the rpm range is only from about 4500 up to 6300. I haven't tuned to SAFC at all yet because of that.

 

you need to quit running N/A damnit, you are starting to scare me.

 

I see your trapping 98's is that repetative or just every so often. You need 22" slicks and you might be able too touch 13's N/A in a 4th gen auto

 

I have run a few 98 mph traps, mostly 96 and 97. I already have 205/50-15 little tires mounted on my stock 15's for the track. I plan to hit 13's N/A this fall when it gets colder. I already have a few new mods that I have not track tested yet. If I can't do it with more power, I am gonna get a torque converter and slicks and do it with a good 60 ft time. I don't think my 60 ft times can get any better now because I don't have any torque to come off the line like you do. I might be able to eek out a 13.99 this fall with some weight savings and perfect conditions. I wish I had the damn JWT ECU with the 7k rpm redline instead of this G-force one.

 

Anything is possible and I can't wait too see you set a new marker for the 4th gens especially autos

 

13s would be amazing. I want an ECU upgrade..

 

Don't get much time at it, usually just one run at the start of the day to make sure everything is ok, but I am going to see what I can do. Don't think I will ever see 13's though because I don't plan on doing anything else to the engine. I would just like one 14.5 which should be achievable.

Would be nice to see a 4th Gen auto hit 13's N/A though, so keep up the good work. I will stick to the liquid supercharger side of the house.

 

Jime how much are you getting your dual stage for? I was thinking about getting one too,becuse it is hard to keep the traction when running the 125. I did a 12.6 @ 107 with a 1.83 60ft. When i look at my videos I can see the slicks spinning, I was gonna do the 150 but was worried about traction.I also wanted to know if you have done any tuning at all with the safc? Maybe the hi,low throttle? I am doing 15.6 n/a, and wanted to know if maybe you could help me out with the safc.

 

I can't disclose my price David because I am sponsored by NX.

Still traction with a 150 but it just rips the slicks and the trans is shifting to 2nd prematurely and then bogs so not good for the engine, thats why I decided to go dual stage. Not sure how I will run it yet, maybe 75, 50 etc will have to experiment.

No tuning with the SAFC yet I have a wideband O2 on order, should be here within the next week or so. My SAFC is just on stock settings ie 0%, so hoping to get that setup soon and that will it will help.

Sounds good on your times, its just a matter of getting the right combo. I am moving next weekend so my time playing with the car is limited right now but hopefully get back at it in Aug.

Will let you know if I make any headway with the S-AFC and wideband O2.
