Honestly, all the haters here bashing the guy = not good. He'll just think you're all d**k and try it anyway. How about providing the truth.
1. E series falcons were never made to go that fast (EL GT excluded). 2. I had an EL with a lot of work done (over 150RWKW), I was running out of revs. I started playing with the ECU, I upped the rev limiter and removed the speed limiter, as the 180 limit came in before the end of 3rd on a dyno = hard to tune. 3. On a dyno (don't do that kinda s**t on the roads), the gearbox/tailshaft/airbags/exhaust all failed at ONLY 192KM/H - proof it wasn't made for high speeds. 4. Cost over $1500 to fix it back up, and that was with me/friends doing the labour. The engine then died only two weeks after getting it back on the road (related or not I don't know) another $1500. 5. Bought myself a GT-P, it's made to go fast, and I have my fun on drag strips and race circuits. 6. Learn from my failure. I'm lucky I wasn't stupid and tried beating 180 on the road, I'd probably be dead. 
Close thread move on.

im interested to know how the airbags were caused to give way at a high speed :s not like they were under any mechanical stress

You think that mechanical failure was smooth/quiet? The impact would have ruptured the sensor on the firewall among other things, static, shock.

I can help you remove the speed limiter if need be. PM me for info.
Most people argue about the need to exceed 180km/h. That is part of the argument anyway. The real argument relates to tailshaft RPM, and diff gears. Not the actual speed as such. In regards to / driveline failures, its all to do with the driveline setup. If you need to go over "180km/h" then install a thicker wall tailshaft. That is the weak link of the e-series, to do with the tailshaft length, thickness, and the MAXIMUM SAFE RPM of the tailshaft. it really is only a ratio to the "km/h" A lot of cars with the same length tailshafts as E-series can spin over 7000rpm without tailshaft failure, but that is with a 3 or 3.5" dia, thick wall tailshaft, made to withstand that amount of RPM. Its got nothing to do with max speed. Also its advisable to install tailshaft loops. |

180 just doesn't cut it...... IDIOT. Its f**k like you why all younger people just getting their licence are stuck driving echo's for 3 or 4 years, because you all want to be "Fully sik" and drives like idiots on the road and kill yourselves and your friends etc. Take it to the track you nob.

Think about it, the car thinks it's going 192km/h then all hell breaks loose (gearbox falls apart, tail shaft starts bashing the under body etc.), of course it's going to deploy the bags.

Thats, odd, isn't it?
Airbags are only supposed to deploy if 2 of the 3 sensors (one near the gril and others on the sides of the engine bay) are crushed. The idea being, not to hurt people in low speed crashes, when their head/body is not declerating as fast as the airbags 'accelerate' out of the dash/wheel. So how does the 'shaking' of the car cause that? (I'm curious in case it leads to bigger problems etc)

There's the front crash sensor, one under the dash, and a third 'safing' sensor in the SRS module.
There was obviously enough shaking, combined with the fact the SRS module thought the car was doing 192 that it decided to deploy. There was no fault codes prior, and once the car 'rebuilt' (with new air bags) no fault codes after either. Had the same shaking occurred at regular speeds, nothing probably would've happened. Keep in mind however when the tail shaft broke in half, the half attached to the gearbox and the half still attached to the diff (wheels still spinning) were flopping around at 5500 RPM until the gearbox failed, and the hand brake was yanked on (to stop the rear wheels). That's A LOT of violent energy being beat into the car.

The SRS module has no idea what speed the car is doing. An impact force equivalant to 25km or over will cause it to fire - this force is fore/aft. There must've been an equivalent jolt to fire the airbags.
Again, it'd be pretty hard to diagnose exactly what caused it.

Yes it does, because it's disabled at under 40km/h

^^^^^^Sounds more like the cruise control .
So if I'm stationary, and someone travelling >=25kmh has a head on with me, the SRS won't activate ?? The SRS is independent of the ECU and a VSS input.

I remembered the speed incorrectly . But the following is quoted from the manual.
Quote: The airbag is a supplemental restraint system (SRS), designed to be used in conjunction with the seat belt. The system uses three crash sensors located in various parts of the vehicle body. A crash sensor is located in the front of the radiator support panel, another inside the vehicle, below the front of the centre console and the third crash sensor is integral with the control module that is found above the throttle pedal.
In the event of of frontal collision in which the speed is is excess of 25km/h and at least two of the sensors send a signal simultaneously to the control module, the airbag is activated. That's what I've been working off, it may be wrong.

 But I don’t see the need to go any faster…. Unless you are planning to do a high speed chase or something stupid. I have a Futura and think 180 is more than fast enough.  The computer reads off the cluster doesnt it???? Or does the computer have its own little special function to read speed??......like using the wheel sensors instead of the transmission speedo gear??? Can someone please clear this up for me?......someone who actually knows.

The limiter is in the ECU itself. It gets it speed from the cluster which gets it from the gearbox sender.
B series get the speed from the ABS system.
