Ok,

So, if you really want your car to shoot a flame out (like a few feet) here is one way I've been told. I've also been told not to use it on the street, which I'll explain in a sec. I wouldn't do it myself.

As you are flooring the car getting ready for a shift, you set up your management to continue fueling as you push the clutch in (and back off for that second) as you go through the gears. It also retards the ignition which keeps the turbo on boost, and shooting raw feul out the back (which will catch fire if the exhaust is hot enough). Runs great, and heaps of fire (think v8 supercars). Cat, no cat, its doesn't matter, as long as you have a resonable sized pipe.

The downside is if you are driving down a hill, backed off, the car will still be feuling - which means the turbo will get HOT. Apparently even coasting down a hill for 30 secs or so can make a turbo glow red and fail.

Another system is to shoot a flamable gas (nos?) out the exhaust from near the diff, using a spark plug to ignite (ah lah Fast and Furious).

not that i'd bother...

That description doesn't just make a pop, its a rather big bang.

I don't think its harmful for a little pop every now and then, most skylines I know seem to have always done it....

You do not need to pump other gas into the pipe to create a flame, I've seen kits that work on a coil pack and a spark plug. They simply spark in the exhaust tip and bang, you have flame. Don't forget boys and girls, those gassesfumes are flamable!

Rice anyone? Ooooh yar, 2F2F....

cars with a cat wont... some cars cats might be badly degraded (if its been on there for a few years etc) so you might get a flame.

Mine flames on the odd occasion... i think. Whether it makes it out the rear end or not i dunno. No-one's ever seen it.

You can tell the difference between a pop and a flame.

The sound is a tad different between the usual pop, and when the fuel catches.

not ture, i have a cat and i get flames (view the sauwa/silviawa cruise video) unless my abuses over the years has eaten it up

Pre-86 cars :(

In NSW (and ACT, which uses the NSW rules), an engine conversion on a car built from 1972 onwards has to meet the emmissions requirements of the year the engine was built in. Cars built prior to 1972 only have to meet the emmissions of when the car was built.

So - if you were to take a 1985 car and put an RB engine in it, you would have to run an exhaust choke... sorry, "catalytic convertor". I think it was the CEO of Lukey mufflers who commented that the best flowing catalytic convertors flowed almost as well as the worst flowing mufflers...

In my case, I can run aftermarket injection, play with cams, turbo etc. etc., and as long as I meet the CO/HC limits for 1971, I don't have to worry about the EPA.

    • Lock me in mate, although I'm not sure if I'll be heading up from Goulburn or down from Sydney, either way, return will be back to Goulburn 
    • Sounds good, we will aim to be there! @The Bogan I'll give you a shout if you are heading up to campbelltown for the meet too.
    • Before I get to the test day, just to finish off the android head unit. This is a demo from car start up....the standard/host system takes a few seconds to boot (same as all v37) but Android comes up quickly. In this vid I'm using the delivered launcher but have set the default to Agami since which is easier to navigate when if use primarily 5 apps. You can see the host system still takes over when required eg putting it in reverse, and you can switch between Android and not by holding the back button 3 sec. It is pretty responsive (fast) but you can see I had to press harder than expected a couple of times.  I still have the phone connected to the stock system, and that also seamlessly takes over Android music playing. v37-android-demo.mp4 The bigger reason that I put this in though is so that I can use Ecutek directly on the head unit. That gives me a dash with logging (up to 20MB only), high and low value warnings on any parameter etc etc. I've run a USB cable from the Ecutek OBD dongle to a USB input on the unit, easy. v37-ecutek-demo.mp4   The unit did freeze on the launcher the other day, I think Agami was trying to verify the license when it didn't have a data connection...will monitor and report back if there are any other problems but so far I'm very happy with the upgrade.
    • Nah that is just crappy GPS mapping, I did have a small excursion (cold tyres, damp track, surprise!), will post up that when I get a chance.
    • So 10/10 times that code is coil packs? I mean if that's the case ill drop the $400USD or so to replace them. I didn't know these cars threw codes before the issue became an issue.
