Well, I went to the drags with the intention of running into the 13's. Unfortunately for every import or fast four (wrx's) there was about 3 trevs. This meant about 20-30 minutes between each run, then some poor guy blew his engine on the strip and dumped oil all over it. So in the 2.5hrs I was there I had 4 runs. Best time of 14.506 with a terminal speed of 103.09mph (165.90kph). So whats going wrong, with that terminal speed I should be doing a mid 13-high 13 (say 13.7, which my mate did on a simular terminal speed in his 180sx). Well for starters the track sure as hell didnt feel as grippy tonight. I need wider tyres (possibly something more grippy, although the ceat's that I have are fairly grippy), some more suspension bits on the rear end (I think the diff craddles are loose as well, getting axel tramp, will probably just over-tighten them to be sure) and I definately need a better clutch, probably a twin plate setup (the stock one was slipping and I couldnt launch very hard at all. My 60 foot time was crap 2.616 seconds. If I fix the clutch and get some better tyres I'd say it would pull a 13.7 quite easily. So all I've done is;

1). 3.25" cat back system (no resonator's, straight through... loudish but more HP)

2). Blitz dual sbc boost controller (set for 0.6 bar and 0.8 bar. the runs tonight were on 0.8bar, I wanted to do a run @ 0.6 bar to see if I could get faster with less power and more traction perhaps, but wasnt going to wait another 20-30minutes to run again)

3). pod filter. HKS super power flow thingy, the green one. Flows the best, only good for stopping bricks being sucked into the engine.

So really I've done basic mods to the car so far, but with the right clutch and tyres I should pull a 13 easily. Just shows you guys out there with 300+ rear wheel HP and running in the 13's you'd be best spending some money on your suspension setup than searching for more HP and the guys with little done to their cars it shows you dont need to spend big $$$ to run a quick car. Between the boost controller and the exhaust there is about $2.5k fitted and tuned (all brand spankers).

hey rob what colour is yours? i was there last night some interesting runs...

but what the **** was with that blue subaru? looked like it was a rex had a zorst, but then it ****ing did a 24.something???

surely even a ****ing RX would do 18 or something?? anyone else see that?

everyone knows skylines have traction issues, in reality i think the time you got may be a little slow but not far off the mark

i dont think youll get into the 13s with those mods. maybe with an SAFC or some kind of management, then some suspension work. but at the moment id be happy with a low-mid 14

rob, as said you'll need to do some suspension, then maybe not try and get your time by going sideways down the track :) and I'm pretty certain (from the skylines that I've seen down there) you'll need a couple more mods to get your 13

hehehe, 13.7 is outta da question ;) :burnout:

happy birthday by the way ;)

Wow thats a great terminal rob, 103MPH!

I can see why you are going to have problems hitting 13s , and no it isn't because you don't have enough performance mods in your engine bay. It's because you have 195 16inch el-cheapo tyres!

103MPH with a better 60" and 13s are there for sure.

2.3 was grandenko's 60'' to run a 13.8 @ 166km/hr, I think Maka ran a 13.9 with a similar terminal and a 60' of 2.5?

You just have to stop driving on the razor blades.:)

Psiko you've got no idea mate. Look at my terminal speed, the car is going fast enough to equate to a 13.7 second pass without a problem, my traction and clutch are letting me down. I will be scanning my timesheet so all you non-believer's can go FOAD.

I went last night as well but didn't do very well :) I think maybe the track was slippery, it didn't feel like that last week.

I just kinda spun thru most of the gears up the track and the best I managed was a couple of 13.9s.

Last week I got a 13.7 which I was really happy with, so yeah, kinda disappointed with my efforts last night...

and I'll bump up the ratio, for every import there was 4 or 5 trevs... I managed 6 runs last night, but the bulk of them were at the very end when they'd all left.

Last week there were less ppl dragging, which was good ;)

Rob

Troy is running an AFC whereas you're not.

He's probably running with 40kw more than your car.

Without either a lot more power or a lot of work in the traction department you will not see 13.7

I hope you can prove me wrong and I'll be the first to congratulate you.

Then I can FOAD whatever the hell that means:)

okay i'll set some things striaght.

my 14.01 was with 10psi, pod filter, cat back exhaust and bit more timing. (power of car was 170rwhp)

my best with the safc is a 14.15 with 9psi, pod filter, cat back exhaust and bit more timing. (power of car was 215 rwhp)

me thinks its all to do with grip and driving technique.

what rpm do u launch at?

what rpm do u change gears at?

do you know the power curve of your car?

these all affect your time.

I was launching at 2500rpm with the clutch slipping. 1st gear was useless, clutch wouldnt bite properly and the engine was revving hard to 7000rpm, 2nd to 3rd @ 6500, 3rd to 4th 6500. The car hasnt been dyno'd yet with the new boost settings (by me anyway). I would have liked to run at 0.6bar, probably have less traction problems but terminal speed would be slower I feel. But needless to say by the end of the 1/4 mile the terminal speed is extremely high.

I'm not saying I'm a non-believer at all

what I am saying is, if you get a 13.7 with the mods you have I will personally eat the shit that's coming out of your mouth

reason for nasty post - I don't like being told to f off and die (FOAD) for no reason

so calm down

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
