Pod Filter Exploded

[jpeg.picky]

First up about my car, VN 3.6 w. Cold air intake, pod filter, FE2 Suspension, Sway bars, Strut Bars (Engine + Boot), Supercharged V6 Injectors, Extractors... car is also Duel Fuel.


Started her up this morning, on gas, gave her a bit of a rev - nothing higher then 3K - as my morning routine before i go to work. Greeted with a extremely loud Explosion... thought it was a backfire first off so start car again on gas and BOOM!.... bugger this, switched it to petrol and she runs fine.

During lunch break @ IBM, popped the hood just to check everythings alright, and damn Pod filter has BLOWN off....

Ideas? as to what caused this? thing is had no warning, as my gauges for oil and temp are as per norm...

keep ya foot off the accelator when starting mate and ull have no more problems. ur not alone tho, ive blown my air box cos ive been used to starting the VK with a bit of throttle.

Thats it, any accelorator on the gas systems makes em fire back through the intake, my old mans jackaroo had the same problem, blew nemurous airboxes apart and ripped the underside of the bonnet apart. Solution, on the intake pipe, there was a hole drilled, maybe 20-30mm in diameter with what was originally a sock over it, basically a good stubbie holder, think one, thats whats on there now. With that, it blows the air back through that at high force rather than blowing the airbox apart, works a treat and was originally fitted by the boys at holden, ill get a photo when dad gets home and post it up for ya's all to see

Yup the old backfire on a GAS VN my mates has done it many times aswell, best option ive seen is to drill a hole in the intake pipe and put a rubber plug in it, it should blow that out in the case of a backfire.

[timmyscommy]

same theory as the other guys, this is mine.. three holes on the intake covered with a wetsuit like material, i also repalced the box with a pod (k and n one) and shes survived many a backfires. i would be buying a better pod mate, i dunno about the other brands but the one i got is reinforced with wire.

[Doctor Sodways]

Yep, wetsuit material, same gear as a stubbie holder, stubie holders work well cos they are already a tube, if its the right size, works a treat

[VN Commy]

So motors running on petrol don't do this then? Cos some times my VN doesn't want to start unless I give it a little push on the accelerator..

[chopsy]

My VN also did this afew times a year or so ago only in hot wheather though it just desinergrated my airbox to nothing.It used to happen when i would put my foot down taking off from traffic lights ect.But since i put a pod on my car it has never happend.

[tropical^fish]

My VP was running extremly well until the other day (my mate drove it and gave it a thrashing, wasnt happy) anyway - i have a K&N filter, re-enforced lifetime guarantee... needless to say, with me driving it for a year it lasted, and lasted well - 5 minutes him driving it, backfired a few times (no rev limiter with the LPG) and blew the insides out of the end of the pod... runs good now, just dont rev it over 7k like he did and your fine lol

[nemodore]

this back fire can also be caused from the gas system leaning out to far aswell. some times it pays to have it checked out.

[s0sage]

some bright spark should hook up a blow off valve in there ..... lol

[tropical^fish]

i had thought about that....

[nemodore]

it is the most common cause of backfire in lpg engine on any car . if u have computer adjustable lpg its easy to fix with the right gear ,if its manually driven then chuck it and get a new one. personally i dont like lpg. as 4 the blowoff valve i really dont think thats gone help.

[PaRaDoX]

ouch, poor pod filter sounds like too much gas in the pipe then it ignited, like a massive backfire.... hope my lpg system dont do that when its finally installed

[HoZy]

I've never had a backfire an i start with foot on accelerator slightly

2years an counting, still safe.

Cheers

My girlfriend VK used to do that on gas, seems to be a gas related issue.

[richie_cky]

jpeg.picky, I work at IBM too lol. Send me an IM sometime, wouldnt mind having a look at your car. Cant say ive seen it around IBM, but Im only casual there. I'm driving a Mettalic Maroon VP, always parked up the front of IBM carpark.

Yeah the intake back fire is only in gas cars. this is cause by leaning out of the mixer causing a combubustible mixture in the intake system. with the trootle opened, there will be a combustible mixture in the intake system so try to keep the throttle closed when starting a car on gas.
worst i have seen with a lpg car is on a falcon, they have blown the headlight out. lol.

[defa]

my dad has a dirty old falcon on gas. and he is getting the rest of the gas sorted out this arvo. but the gas bloke said something about having a bypass tube in the intake to stop this backfiring stuff. i don't know exactly what he is on about so i probably shouldn't be commenting, but he was saying it is a common problem and that is how ya fix it..
so i would suggest that all you people with gas find out about it so it doens't happen
