Internet record

Its fun to go after records like that isnt it. I took the similar quest in my car. and finally got 12.81 at 106.3 before putting on heads and cam.

 

awesome times and driving dude. your car must have a really good tune aswell. keep up the good work!!!

 

you need to update your sig now....you don't run 12.9 anymore

 

Gongrats man, a job well done. Been following your runs since 2004. I remember you ran 1.69 60ft when you first entered the 12's.

How does it feel with these diff bushings (street wise)? Just got my self the rear ones

 

Good job on your time. We go to the same track.

 

Too bad we didn't get a chance to line up against each other that night. I would have had you on the launch but you'd be reeling me in at the end! Get some ET streets for your car and you'll run low 12's/high 11's for sure. Maybe we can meet up there in the new year.

 

Bushings are great. Less slop in the rear end and no issues with wheel hop. Don't have to worry anymore about breaking the bushings with 6-7k rpm launches!

 

4 sure. Next time I go I will have some, see you there.

We were also using 8kg/mm springs on the rear, which may be a little stiff for drag racing. With the new SPL arms it is pretty easy to swap out the springs, it may be something worth trying in the future to get more weight transfer to the back at the launch. Although right now I have more traction than I can deal with, so I don't know if that will be worth trying just yet.

Finally thanks to Kuah and UpRev/Cipher for the custom tuning, that was the only power mod this time around, but enough for the trap speed record for NA

Next year this time I hope to be running ported heads, cams, and new exhaust setup, which may no longer qualify as bolt-ons, but will be staying NA.[/QUOTE]

Hmm, I didnt realize how much suspension helps with traction and weight transfer...

Soulds like your tuner definetly knows what he is doing!!!!

 

Have you broken any stock parts throughout this whole process or run into and major problems?

 

by any chance do you know the size of the tubing on the single exhaust system your running? is it 2.5 or 3"?

 

Only thing I have broken is the stock rear diff bushing which I replaced with a solid aluminum one from SPL. While I was at it I replaced the front diff bushings with solids from SPL as well. They're at the bottom of the page http://www.splparts.com/Parts/Z33/Su...nk/default.asp
A much cheaper option than replacing the entire subframe as Nissan doesn't sell the bushings separately and I'll never have to worry about breaking these.

 

I measured the 5Zigen ProRacer A-Spec at 65.7mm(2.6inch) id and 69.5mm(2.73inch) od.

 

Back from the dead. I was wondering what kind, and size of tire were you runing on your Z for that run?
