only got 1 run in as i blew an intercooler hose mid 2nd run and i didnt bring any tools to the track :(

from memory it was 13.515 @ 112mph or similar - i am sure i posted my time previously.

i felt like it had a shit load more in it, launch was poor 60" was 2.2 / 2.3 reaction time of .600 i have only been to the drags once prior ever, usually hit barbs :)

Ah pity, I had some tools there you could have borrowed! Was that you that parked in front of me and my mates near the scrutineering shed? I was in the white 34, mates had the maroon 32 and the white Type-R?

Again though, 112mph with 366rwhp... It's a shame you only got one run in. How'd you go at Racewars?

Reaction time isn't going to affect your time. Interesting enough your time seems VERY similar to my first ever outing on my GT3076R with a soft tune in it - 14-15psi, 270kw @ hubs (equate to around 245ishrwkw on a DD?) did a similar time and trap speed on street tyres. What boost, and type of dyno was that on?

Here's a link for the dyno plot and time slip from back then: http://www.dragtimes.com/Nissan-Skyline-Timeslip-13888.html

Its as if you are online waiting for something!! :whistling:

. How'd you go at Racewars?

lol racewars got half a day of racing in for the roll on 400m's then something gave way, goes to Galvsport monday to work out what happened.

Right, not getting too excited just yet as it may be nothing, but I MAY have found a problem that could have been holding me back.

I decided to raise the suspension back up to a driveable height today, and had to take the front bar off to get my jack under. While it wasoff, I noticed the 90 degree silicon joiner on my cold side cooler piping was being crushed against the body where it went through the hole to almost half its diameter :/ Not sure how it happened as no matter what I did it just didn't want to sit elsewhere, so in the end I cut some length off the joiner so that it would sit higher up, as well as using a die grinder to open up the hole a bit more.

It is now fine and back to its full dimensions, so should flow a lot better. Also quite lucky that the joiner isn't damaged at all, I imagine it wouldn't have liked being crushed like that. Anyway, I will take the car for a drive tomorrow and see if it makes any difference to performance.

Any differences after the silicon hose is replaced?

Releasing a cheap bolton turbo that is capable of doing 280rwkws internally gated. The ATR43 3.5. I've done a fair bit of sculpturing in to the imported china turbine housing. This turbo is capable of making 350rwkws on E85, external gate.

I will mark this price on $1100 including the oil line and high pressure actuator.

Result of this turbocharger is page 366

Note since the turbine end is largely over sized. Make sure the factory dump pipe gasket and dump pipe flange is all touched up as its not in the way of flow.

I will sculpt another turbine housing for it that supports both external or internal waste gating like the SS2 .82.

As explained before the savings comes from the turbine housing (cost by KGs), that requires less parts or machinery work.

Compare to the ATR43xx series, because they were built in matched housings, they do picks up more mid range, and better response. So they are still the better bolton / Ext gate turbos.

But like I said it is a cheaper alternative, and will perform better then standard high flows. And I guess the biggest advantage is that a donor turbocharger is not required, which saves lot of time and shipping fees.

I will see if there are room to dropping pricing on our current standard high flowing service. and will pass that to our customers.

Did a little bit on car this weekend, nearly finished, just had Matt from Nistune do computer and picked it up tonight, might

turn the key next weekend, just have to fab up external wastegate pipe., have all the pieces just have to cut and weld them

during the week

cheers

Had Tao's car out at heathcote today and on slippery as hell tyres (255 RSR's) we managed consistent 124-126mph runs @ 19-20psi. (330-350rwkw)

60ft times were 2.4 to 2.6 seconds and ET was 13.02 - 13.3.

Time for some decent tyres and we will revisit heathcote. Axle tramp pretty much all the way to 4th and 3/4 track.

haha we submitted the post on the same time.

Just came back from Drags today. I can still taste rubber in my mouth.

This is the very first time my car's on the drag strip. It was some how of a test run. Trent was my driver for the day as he would know whats going on incase if any issues. It was a factory weighted R33, We did not do any weight deduction work to the car.

We've got 6 runs though out the day. Because observation of the car's performance is mostly on dyno, so we did run in to couple of issues. And the Federal RSR tyres are horribly bad for drag strips, no grip WOT in first, 2nd and 3rd.

The problem runs:

First run was 17.9sec with cooler piping popped.

I guess thats a NA R33's drag time. @ 75m/h

2nd run was 14.94 Hitting boost cuts. 78.1 m/H .

I install and trail 2~5 different combinations of turbos every week, but did not record the EBC settings for individual turbos.

3rd run was 13.92 @ 116.7 m/H.

This car came with a quick shifter, how ever it doesn't go into gears in high RPMs, this problem carried on to all runs done today.

4th Run was 13.66 @ 122.28 m/H.

Car had fuel surging issue

5th Run was 13.55 @ 118.17 m/H.

Car continuing to have fuel surging issues. It wants to stalling or bogs down after gear shift. After more fuel added (3/4 of tank full) this problem was finally solved.

The last two runs were mechanically trouble free apart from unable getting into gear and no tyre grip till 4th gear.

6th Run was 13.26 @ 125.63 m/H , 60ft 2.3 sec, @ 23psi of boost. (Add: After check data log it was 20psi instead of 23)

Because of the car had no traction, we finished the day with a lower boost setting and surprisingly it run faster with less m/h.

7th Run was 13.06 @ 121.42 m/H, 60ft 2.5 sec, @ 20psi of boost. (edit: After check data log it was 18psi instead of 20)

The turbocharger run today was a externally gated ATR43G3 in .82 turbine.

We should be hitting the strip again on 12th May. I will replace the gear shifter and Will be getting some proper MT tyres. Hopefully be hitting into the Mid 12sec with around 130m/h speed.

Decent mph to HP converter the guys linked me too today at the drags. They were using it on their 8 and 9 sec cars

http://www.wallaceracing.com/et-hp-mph.php

average r33 weighs 3060lbs

actual wet weights for GTR

R32 Skyline GT-R Specifications
GT-R GT-R Vspec
Weight 3262 lbs 3306 lbs


R33 Skyline GT-R Specifications
GT-R GT-R Vspec
Weight 3373 lbs 3395 lbs

R34 Skyline GT-R Specifications
GT-R GT-R Vspec
Weight 3388 lb 3432 lb

yeah should add all shifts were done 1 neutral 2nd then neutral then 3rd as shifter would not allow single action changes. so prob another few mph as each better change seemed to net a few more mph and better time. An honest 128mph run should be achievable on this little turbo.

tao i checked to log too at the end and all runs were closer to 20psi not 23 too. Last run was @ 18psi.

    • 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"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
