    sounds sad but this is bugging me now, i have never come across a 106 gti or saxo vts that doesnt pop if you give it some shit on idle, and most do it on gear change. no matter what i do it just doesnt have any of it, been told you can do something with the carbon canister or remove it and it does something or is this just myth? i have pipercross viper induction kit, and straight through pipe with piper backbox so cant see what the problem is?

    you need a decat and a manifold. i believe it's the manifold that get's you decent popping.

    yep, decat and or 4 branch manifold.

    done it for me.

    doesnt pop all the time, but sometime son gear changes up and down.

    and usualy when stood still and you blip the throttle slightly it burbles abit when the revs settle back down.

    sounds nice

    ive got a raceland 4-1 decat manifold and a piper manifold back stainless system with centre silencer.
    only other mods are a custom induction with a K&N cone filter.

    decat, manifold, blah blah blah. Its just unburnt fuel being dumped into the hot exhaust, ergo, overfuelling and killing your valve stem seals

    I have a S' through system. As i have a MK2 VTR, the CAT is in the manifold and i've not removed this yet with my Sportex back box it pops and gurgles nicely.

    Edit: I meant VTR

    my valve stem seals are on the way out. and have major over fueling. but the flames and poping on both up change and shut off well worth it lol, big soot patch on the rear bumper.

    This is what annoys me. It is already decat, straight through droo manifold to backbox, all it does is a few crackles when im releasing clutch slowly at low revs shit being the odd one out ha

    I grew out of wanting pops, bangs and flames when I stopped being 17, but I still do love flicking the kill switch on the bike to scare people at bus stops and in tunnels with a massive backfire! A Saxo doesn't compare!

    But FWIW I've got a standard manifold, Magnex decat stainless centre silencer and backbox. It gives a nice burble on idle and a deep bass sporty tone when given the beans, I'm not into raspy rally noise unless it's a full on track car and mine isn't. Mine pops when changing up on the beans, you won't get yours to do it unless you get rid of the cat.

    You need to see a doctor. A proper engine making pops, bangs and flames is one of the great things about tuning cars.

    You need a good manifold, and a correctly matched performance exhaust system that has high gas speed so fuel is scavenged from the inlet when the exhaust valves are open. Then fuel and air is drawn into the hot exhaust and you get the right sounds. Longer duration camshafts such as the Cat cams 1321708 obviously help. you certainly dont want a horrible restrictive cat though.

    It is running the larger rallye/xsi injectors on the vtr injection setup however. Shouldnt think that would make too much difference

    Really, I thort mine would after the exhaust but no so picked the cam up cheap and had it fitted still no pops,,, would advancing the timing encourage it?
  27. Saxperience Post Whore Joined: Apr 2011 Posts: 9100 Amazon green VTR 16v, Inferno RS clio 182

    Mine is running standard timing as its the normal xsi cam. The only thing not standard is the xsi injectors which have been popped into the VTR injection rail as the standard vtr injectors wont sit down in the head correct as they are too short.

    Do the xsi use the early blacktop head with a wilder cam, I have a 4bar fpr to try now cam has been fitted may help.... Over fuled and bogged down before, maybe rallye injectors and the 4bar fpr is what I need,
  29. Saxperience Post Whore Joined: Apr 2011 Posts: 9100 Amazon green VTR 16v, Inferno RS clio 182
    #29
    Yeah its a black top head - I believe the xsi head is the same spec as the rallye one, so more aggressive cam and harder green valve springs

    As kam said, a well speced engine giving it some with pops,bangs ect sounds amazing but if it's a spotty cunt in mac D's reving his furio then it's lowest of the lows...

    Any truth in this anyone? Since fitting my decat manifold I get a few pop/spit type noises on gear change...no flames as far as I know but I wouldn't want it to be doing any harm. :/

    I cant see how it would be doing harm - hows it going to alter the fuelling providing your lambda and the other sensors are all in working order? Stem seal changes arent too hard a job anyway

    Truth be told I'm just jealous lol, piper 285's bmc, btb mani, btb exhaust and a pred ecu and no sign of it. Is be happy to change the vss every now and then for some nice pops and bangs. My main concern is damaging the lambda

    Same mate, well it must mean the cars running a bit rich if its popping I would of thought? Although spoke to a mate of mine who used to deal in highly tuned imports and he said running a little rich on a tuned car isnt a bad thing, all the high spec turbo cars etc do it....I just would rather not have to change the valve stem seals as my last car had this problem and its embarassing in the mornings to say the least lol.

    Its weird is that, mine used to do it ever so slightly and rarely just with a cat back system and induction kit, now with the 4-2-1 decat I get it quite often, sometimes lets off 3 or 4 pops in succession on a downshift form 4th to 3rd, if it was killing valve seals though I'd rather it not do it? Why would it damage the lambda? At least theyre a 2 min job to change tho haha

    I dunno what to suggest on yours though mate aside from pouring petrol down the exhaust lol

    Mine doesn't do it much on its own accord, not as much as others I've seen.

    Try gunning it right thru the revs in first and second, then when you get into 3rd, let the revs die down for a few seconds, then tap the throttle and it should let some beastly pops off!

    Init lol, and ahh I see, I suppose thats more because its kinda forcing it to do it, like messing with ratios etc, if it does it naturally that might be a different thing?

    I don't really give mine stick to be honest though, if i gun it through first and second changing at about 5k revs, on the change I'll get a series of rasps as i change, kinda like when you rev your accellerator near the limiter, the pops more come on downshifts, or if i cruise along in second, upto about 3-4k revs, and tap the accellerator with short sharp blips...especially works on downhills...try that that might give you some popping lol.

    My ST pops like hell, variable valves at 2000rpm, always seem to drop one right outside the one house as i come home, round the corner, bit of gas, let off to go round the next... POP POP

    A SS fanimold and a decat will crudely do it on a saxo, as posted previous it does sum up saxo drivers though

    Now i have a S/s mani, it pops and bangs even more. Quite embarrassing.

    I think the idea is for the exhaust + engine to be very very hot for it to pop and to catch the right rev.

    I'm sure Sportex back boxes have that Rally sound and is supposed to pop and gurgle added to its characteristics?

    Mine was decatted yet didn't get no popping, But was over fueling a bit due to the crappy lambda in it wasn't a good one looked like a cheap one, so I tested it with my multi meter first then also put it on a diagnostics machine and lambda was reading rich mixture.

    So i replaced it for a Bosch one was so much bigger than the old cheap on, plugged it back into the diagnostics machine and now was reading lean mixture.

    Since changing it to the newish one it pops all the time changing gear everything, So don't think its always the case of having a rich mixture and is still saying lean mixture....

    What a load of bollox sone people talk hahaha.. a tuned engine will of course do all the above !!! My vts OS running cams, Supersprint manifold, Supersprint race tube and a magnex box, plus some other engine mods, nothing serious, and it sounds the tits !!! Does what it says on the tin, goes little a little rocket, and sounds awesome...
