1990 Skyline GT-R - Jet Silver Metallic
It'll run someday
-
Finally had a decent ran today (I made a post earlier about how bad my times were). I ran 13.4 @ 104.9mph with a 1.95sec 60' and a 0.3sec reaction. I need to launch higher (launched around 5500rpm this time) and shift better/later. The air temperature was very hot around 30degreeC+, which a drag guru told me will make car slower by around half a second. I need to break into the 12s!!!! Kinda happy now I'm in the low 13s, but I want to do better. My setup is:
Kakimoto cat-back
Apexi Power Intakes
Probably an aftermarket cluch
And thats pretty much it.... Stock boost!!!
What you guys think can I break into the 12s?

I think you'll be hard pressed to hit 12's. Maybe on a cooler day with a better launch. They say every tenth off your 60 foot is worth about 1.5 tenths on the top end. On a 15-20 degree evening with a 1.7-1.75 60 foot you could do it.1990 Skyline GT-R - Jet Silver Metallic

I hit a 12.8 @ 104mph in my gtr with full exhaust.

Oops.
I went through the trouble of putting my crappy vid. on here but forgot about this thread.
D/A = about 1000 meters
1st run, left all my crap in the trunk (including a sandbag that I was going to use for balast manipulation) left the boost controller off (.9 bar) and left the silencer in the muff.
RT....... don't care ( always over 2 sec. )
60ft......1.79 sec.
330 ft....4.951 sec.
1/4 m....12.411 sec.
mph......116.09
Last run of the day, all the crap out of the car (including sand bag, didn't do squat), boost controller on low boost (1.2bar) and silencer out of the muff.
RT........still don't care
60ft......1.85sec.
330ft.....4.860sec.
1/4 m....11.242sec.
mph.......127.55
As you can see there is a whole lot more in the car. I still have 1.5bar on high boost and I can improve on my launch a bit. On 1.5bar I expect a 10.80 at about 132ish mph.
Stay tuned.....

The boost controller wasn't working for some reason for the first half of the day. Near the end it started to work and it was set at low boost, I didn't know why so I left it alone and ran it like that. I was also getting some tire shake at low boost in 2nd gear and need to take care of that before I run it at 1.5bar.
Hooked hard though, the worst part was trying to find the sweet spot in the launch technique. Not worried about the motor, more worried about the tranny.
