Well I made a single pass at PIR last night. I ran a 13 and they wanted me to get a helmet... which I thought was a waste of $5 given traction was not to be had and I wasn't able to launch my car (new clutch assembly and slave cylinder going in Tuesday at Nissan, thank goodness).

This is what I ran bone stock at PIR, using 26psi in the rear tires, launching from 3500 in the right lane (faster of the 2).


Now this is what I ran after intakes/exhaust/gears in the left lane. Didn't touch the pressure in my tires (left it at 36psi) or adjust the dampening on my coilovers (3 front, 2 rear, should of gone full stuff front and full soft rear). I took off by bringing the revs to 2k rpms, letting out the clutch and adding throttle once the revs dropped about 1700. I punched it from there. First gear seemed to stick quite well... but when I hit 2nd my car burned the living daylights out of the tires. Car started going sideways, hit a really rough patch in the pavement and got a bunch of wheel hop. As soon as the car finally caught traction I had to shift to 3rd. Shifted to 4th just after the 1/8th mile mark and rode it out til the end. This is what I ran:


In the right lane was a new ~06-07 GT with cool air intakes, flowmaster exhaust and a dyno tune (305whp). Yes I beat him. I think that 13.68 was his best run that night, I watched him run a few 14's lol.

I need to get my hands on a set of drag radials and spare rear wheels... The 4.08 gears were a big help (I basically took off from idle and trapped 3mph better than I did stock...), I just need some rubber to put the power down now. My quarter mile time didn't really improve... however I was satisfied with the relative improvements. ~3mph higher trap, I pick up 23mph in the back 1/8th instead of 20mph. Now I need to work on traction and the driver mod.

 

That's great news, just work on that launch, and your times will drop significantly.

 

Ya, your 60' is all that is holding you back. You have low 13's in your car with a good launch. Even a 2.0 60' should get you about a 13.4-13.5.

 

Last time I was out at PIR launching from idle (still stock) I ran 14.0's at 100mph. I'm not stopping at low 13's. Once the test pipes are on I'm working on those elusive high 12's

 

DO IT! DO IT! DO IT! I too am waiting.

 

I ran a 13.4-13.5 stock multiple times launching with a 2.0-2.10 60' time. Better launch resulted in a lower trap and about the same time down the track.

 

I don't think I can go lower than 100.96 that I did stock. You should see my repair thread in Engine & Drivetrain. Nissan worked on my car for the clutch pedal issue... Turns out it was a leaky slave and the clutch had fluid on it, resulting in a burned up flywheel from the slipping clutch.

 

I still say 13.0-13.1's are possible stock, with cooler weather. I even think a 13.2 is possible right now, in the heat. With your trap, and a 1.9 60', you would be running 13.2 in the heat.

Who knows, maybe someone will hit a 12.9.

 

Still waiting for it. You better not dissapoint Veetec..

 

one of these days u need to come up to pacific raceways, i trap at 103 here stock, 106 with just bolt ons would be a sweet improvement

what do top out in 1st, 2nd, and 3rd with the new short rear? u said 116 in 4th, right?

also what rpm are u at in 6th at 60, 70, and 80?

 

tune in next weekend for some east coast action...

 

1st: ~38
2nd: ~62
3rd: ~88
4th: ~116
5th: ~145

6th at 65mph is about 2700, 75mph is about 3000 and 80 is about ~3100-3200

 

and i forgot to ask in the last post, what kind of gas mileage do u get now?

 

Freeway? 22-24mpg.

City is around 17-18.

 

I agree with 13.0 to 13.1 being possible, but the run I had was a "conservative" launch (clutch issue) and a REALLY hard run the rest of the way. I shifted quickly and never let the gas off the floor (past the launch point) so I don't think there is much to be gained there. No wheelspin with my 13.4, and .1 off the 60' when the car is maxed beyond say 30' is going to do only .1 off the ET (from what I experienced repeatedly last week). 13.3 yes, 13.2 no.

If I have 75 degrees and run a 13.30 I will be exstatic, and I think that at "STP" where I get a DA of 100-200 feet I should run 13.2-13.3, lower obviously lower times, and higher = higher times. But I may be wrong as well and the car may better those numbers, more runs will tell

 

You do not need test pipes to run 12's. Get a set of real "slicks" and walk the car out of the hole at about 4000 rpms with light slipping. Once you bang a 1.8 60 foot you will be right there.......

 

Peak do you have any mods yet? Your MPH is pretty impressive.

 

I'm quite well aware of this. Been looking around for at least a nice set of DR's and spare wheels for the back.

 

I do have a sub....but thats it.

I take the speaker and box out any time I go to the track, and its been out for a few months, but the cap/amp/rack stay in the car since they are mounted in the cubby behind my seat. I just cut the power from the battery to them and discharge the car when I take the sub out. So I'm actually running +50 lbs (equivalent of me weighing 205 lbs since I'm 155).

I figure its not enough to make it worth my while to remove it, I'm just running for fun anyway.

I may go to a non-staggered setup of tires (255 all around?) and so that will bump me to bolt ons, but otherwise it's gonna stay stock for a while.

The MPH however, has come up SIGNIFICANTLY beyond 5,000 miles. The car is noticeably faster, beyond what I've learned from it

 

I've got pretty much the same deal. I pull my two 10's out but leave my two amps in the car. Never cut power to them tho, takes some load off the engine if you do?
