Just flat shift and every 3 months you can "order new gearbox and ship overnight from Japan".

Sounds like a good plan, "We'll put it on my tab at Harry's".

yes flat shifting is where you have accelertor flat to the floor and you have a quick stab at the clutch and change gears, have done this a few times for WSID in gtst33 216rwkw, no problems as yet. (box was just rebuilt 3 months ago) keep doing it, it will smash something, but i keep it all very smooth too.

not really back to square 1 thats the point of the BOV to release the pressure so its got somewhere else to go other than back down to turbo and spinning it down (and worst case, damage)

and given you change with high enough revs you shouldnt come off boost even if you dont flat shift

not entirely sure of exact point of flat shifting (never really liked it, prob cause never had dog box) but i would say (given strong box) it gives a jolt of speed/power when gear changed as opposed letting off go pedal and having to apply power AFTER gear change

I was always under the impression that flat shifting involved keeping foot to the floor and no clutch. V8 supercars do it all the time (but they can rebuild the gearbox after every race if need be!). I've always referred to leaving foot to the floor and using clutch as a power shift. The revs build during the shift and when you get the clutch out engine speed is greater than road speed and hence the car will surge forward. It can be enough to push you ahead of another car during a drag. I don't do it myself as it puts excess wear on the clutch and gearbox.

lol at this thread! especially the 2f2f references. We would all know better without it.. Here's what I recon, v8 sc's have a dog box and to change gears they just ease off the gas and push hard on the gear stick in the direction on the next gear and it should slam into it. The lifting of the gas helps it pull out of gear. I think you need to double clutch on the down change only though. Only Vin Diesel needs to double clutch on the up change...

I know this chick who's fiance had a dog box in his liberty and she said it was a pain in the arse to drive around town because of the double clutch on the down change. However, the up change was sweet! Just lift of the gas for 1/2 a sec and SLAM! Then he sold the car to someone who didn't double clutch it an suprise suprise, it broke about a month later...

.......shall add that I'm not really a V8 SuperCab fan, but seeing the incar footage of Greg Murphy is a good example of how to drive in a "drag" situation

Nah if i remember correctly, one of the commentators mentioned some fancy technology that they've just employed that makes it work pretty much like they used the clutch to change gears, but it reduces the gear change time slighty as they dont need to lift off/push down on the pedals again... Without placing any more stress on the gearbox then they usually would.

Mind you, i heard that about 3 months ago so my memory may be slightly off.

damn you gotta teach me that skill

EDIT: although the BOV woldnt release during a flat shift cause the throttle doesnt actually close so... not that hard a skill after all

The most important bit is the launch. U want minimal wheel spin so u know ur getting maximum traction, control the clutch firmly so u dont bog at all, but so u still get power to the ground.

I raced another r33 tonite, i was lucky with a neat launch and got the jump on him, he couldnt close the gap. then just concentrate on your shifts, smooth and quick. u dont need to necessarily redline it either.

1st to second is the main shift. so practise practise practise...

people say you loose boost but remember the exhaust coming out is still traveling fast so by the time your in the next gear and the bov is closed there still should be boost there....

RIGHT?

thats the point of the BOV to keep the turbo spooling therefore not loosing any boost

You'll also find that the V8 SC guys have ignition cut on their clutches which, obviously, cuts ignition for the splilt second it takes them to jam the gears, hence they keep their foot flat on the throttle.

They also have a soft limiter which will keep revs pegged at 7500 between gears, such is the beauty of Motec.

I used to flat shift 1st to 1nd in my VN V6 5 speed commodore all the time, but couldn't do 2nd to 3rd. Mind you, it took we about 0.1 do rip it from 1st to 2nd!!

I ran a 15.2 in that car. It rocked!

Is that the same Motek exhaust found on Honda Civic's?

    • 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"
