I removed the exhaust at the Cat and increased my timing by 2 degrees because of the octane booster advantage. Also modified the front bar for better flow through the cooler and heat wrapped the exhaust the day before, which made noticable difference to intake temps.

My best run however was with the exhuast on.

Thats some impressive power your making out of those relatively basic mods. How long ago did you install the PowerFC, early on or later on?

14.7psi is abit high on the stock turbo, I get told that 12-13psi is a risk on warm-ish nights.

I think if you can get your traction problems sorted (thankgod someone else gets axle tramp, was beginning to think i was the only 1) then you should see a 12.7-12.8 easily.

oh i get axle tramp alright.. although i am not quite sure exactly what it feels like so not positive! If its the feeling where you're tyres aren't quite squealing and your ass end feels like its bouncing up and down while the wheels are spinning then i get axle tramp big time?? so you are not alone.

As far as i can tell the best way to fix it would be get rear suspension as hard as rocks or put 100kg in the boot. I have pineapples as well, reduces it a bit but not enough as i would have liked.

Thats it alright. I think my car launches harder with 2 people in the back then what it does with just myself. The extra weight most deffinetly helps. I've got 2mth old Koni Shocks and 4mth old Pineapples, my last bet is new Dunlop FM901's to replace the Falken ZE502's. If they dont fix the problem (or dramatically improve it) im not sure what else can be tried. I just wish somebody could give a reason as to why it happens (too hard, too soft, wrong setup, etc).

Have you thought about going for a solid alloy spacer in place of the front pineapples - I have heard it can work wonders, just locks the whole thing up.

yer..same prob.. I've got the Falken's as well. It's just that the skyline is not too balanced.. weight distribution could be a lot better for dragging if it was more even. A full whiteline kit would do wonders if you want to spend the money.

I can probably do a bit better and get a mid-13 but not much better i don't think with my current setup and a few tweaks.

Hmmm.. I've only got pineapples on the ass end actually as i thought that was mainly where it would be needed in a RWD. Would I get gains from having them on the front as well?

I was running 17" 35 series tyres with 20psi. The track was ultra sticky. First run I tryed with a burnout and ran a 13.6. After that i decided to skip the tyre smoking and drive around the water, ran constant 13.1's and the single 12.9 after that.

benm: I installed the FC over eight months ago.

111mph! what the!

I think I'll get a 12.9 soon but, 111mph is damn fast and indicates alot of horsepower.

Go the whales!

I think that puts the R32 boys in their place, they need hiflows toget those sort of times :P

What was the 60ft? (I'm guessing a 2.1)

Looks like AIR got its shit together this time! The warmer day time track temp' would certainly help. It was faaar from ultra sticky last s/meet :P.

Damn I wished I'd gone now :P Nightcrawler set a PB this meet too.

Dave,

111+mph is more than some people would have you believe the stock turbo & injectors can manage!

That little stock turbo is a freak for sure :P It provides minimal lag, hence the quick 1/4 even with a so-so 60ft, yet has big top end to run 111+.

Matt,

be very careful about what you upgrade your turbo with. You could go backwards!

      Duncan's V37.......race car?

      By Duncan · Posted

      Before I get to the test day, just to finish off the android head unit. This is a demo from car start up....the standard/host system takes a few seconds to boot (same as all v37) but Android comes up quickly. In this vid I'm using the delivered launcher but have set the default to Agami since which is easier to navigate when if use primarily 5 apps. You can see the host system still takes over when required eg putting it in reverse, and you can switch between Android and not by holding the back button 3 sec. It is pretty responsive (fast) but you can see I had to press harder than expected a couple of times.  I still have the phone connected to the stock system, and that also seamlessly takes over Android music playing. v37-android-demo.mp4 The bigger reason that I put this in though is so that I can use Ecutek directly on the head unit. That gives me a dash with logging (up to 20MB only), high and low value warnings on any parameter etc etc. I've run a USB cable from the Ecutek OBD dongle to a USB input on the unit, easy. v37-ecutek-demo.mp4   The unit did freeze on the launcher the other day, I think Agami was trying to verify the license when it didn't have a data connection...will monitor and report back if there are any other problems but so far I'm very happy with the upgrade.

      Nah that is just crappy GPS mapping, I did have a small excursion (cold tyres, damp track, surprise!), will post up that when I get a chance.

      So 10/10 times that code is coil packs? I mean if that's the case ill drop the $400USD or so to replace them. I didn't know these cars threw codes before the issue became an issue.
