-7's on 98 wont make 320-330

or

-7's on ethanol wont make 367

or both?

on top of Dyno's being a tuning tool.

Never had same results from different shops. I have Dyno charts that vary by 50kws

R/R seems average for ESP

Shoot 6F not 8 as it is sometimes to give better readings.

I don't know the capability of -7's on ethanol. What is their max?

Look Team,

Iv'e had heaps of fast cars, and this one seems nice and punchy. Even if it's within 10% who cares... It's still a built GTR.....That runs on Ethanol and a Haltech.

Feel free to meet me on the 24th of Jan at Wakefield for the fifth gear trackday. I'll be there as per usual, not hating on a keyboard.

Cheers. James

Great power James. You were a monster on the track day and given this power you'll be hitting 1:06's on the 24th? haha

Don't worry about the haters, everyone is going to have their opinion with a select few actually giving a thumbs up. I think people take it personally when a tuner gets more power out of something someone else couldn't. Should've seen what people said when I got a PowerFC as an ECU haha !

Might come down and watch on the 24th :)

not hating.

just saying that dont be disappointed when it doesnt run 130mph at the strip.

Also

esp is at 1800ft elevation and its summer.

so add 6% to that power figure for sea level conditions....makes it 390rwkws....

from -7s @23psi

but is wasnt the peak figure that made me say -5s it was the shape of the curve

not sure why everyone is on the defensive bandwagon lol isn't the whole point of a forum is to share info so we see what setups work for others, nice GTR much better track car than the 4 door :nyaanyaa:

Exactly,

I'm not trying to take anything away from James' car.

Id be happy to own it myself.

But when a dyno sheet pops up with 40kws more than every other -7 2.6 setup out there, and there are lots, there will be people who ask questions.

When I went searching for results for E85 on dash 7's I couldn't find any. Most peeps seem to go bigger, but they were already on the car so why not give it a crack.

Obviously I had it flex tuned and on 98 it made 300kw which seems normal. Perhaps -7's just respond well to E85.

As this was my old car I can confirm the -7's. The higher compression pistons probably help too. As for dynos when this car was running 98 it made 310kws at JEM and 296kws at ESP, so i belive it. Also wish I had gone the E85 route now....

Happy to see you looking after the car man.

Yeah but what we find here is arm chair experts that have never owned a GTR in their lives basing opinions on what they've read rather than real results.

It's not that different from results i had with -7s from a totally different workshop. I wasn't on E85 yet I had significant more work than most people with those turbos (head work, cams, 2.8 etc).

^^ Hey Shaun,

Well, I was told by ESP that the center diff, or is it transfer case, needs some love, (a change of fluids) and is causing the wobblieness on the graph, so maybe do both at once? haha

But really right now it is frighteningly quick as is. Very different car now. The E85 makes it come on boost a lot quicker and ramps harder.

Feel free if you want to come visit, and i'll take you for a spin.

James

    • 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.
