99RON Fuel..

  1. #1
    I know the difference isnt really felt on a standard-ish car unless being mapped with 99RON fuel etc but would in theory a higher octane fuel help towards pops and bangs? or is it no different? would make tunnel runs a little more fun!

    trieed it in my vts made no difference what so ever its alot of extra money for a few pops and bangs i have a 4-2-1 and a full "2 saxsport and it pops too much already fun on a blast out but horrible in town

    If anything make my car bang less

    Pretty pointless running 97/99 Ron fuel unless your car is either highly tuned, or the cars from another country that naturally uses a higher octane of fuel

    Using 99 Ron will make next to no difference on a mildly tuned saxo

    Yeah ive got the 3'' Saxsport on mine, cant really hear it popping from the inside, i imagine it does, i remember when my corsa was stripped you could hear it popping all the time yet when it had the interior in couldnt hear nothing, i imagine its the same story for the saxo, I only usually wack in a 10r at a time and for an extra 60p a time if it makes some more pops and bangs then im all up for it.. such a child

    You de-catted?

    good luck getting a vtr popping on the over run

    i get a few now and then, when my 4-1 manifold then straight to back box is really really hot if im lucky not on command like my other car, now thats fun can make people jump on motorway

    higher octane fuel burns better you usually get pops and bangs out the back with un burnt fuel

    I use normal unleaded fuel. I can get pops and bangs going up and down in my VTS. Sometimes when changing up gears around 6.5k i'll get a pop though. Going down it rumbles with the odd bang

    My VTS sounds like thunder in tunnels, I am genuinely not joking.

    VTS' love to bang on upshift, if timed right they really do bang aswell! and yeah they crackle on downshift too, got a video on Facebook of my mate 16v with the exhaust which is now on my car, sounds completely different crackles like a goodun on downshift and bangs going back up, dunno if you can see this! Car belongs to samstar on here btw 16v VTR, Supersprint mani, Saxsport 3'' in video (now has 2'' the 3'' is on my car)

    my VTR still pops to fuck even with a cat in the system
  13. #13
    is the cat empty though?
  14. #14
    Nope, just a 4-2-1 and no centre silencer
  15. #15
    Not like that ross.

    Just got a 421 cat no silencer and 2" tip.

    my vts pops and bangs, here is the video


    although now she doesn't pop and bang as much as it isd to since changing gearbox to a 1.1 as previously i was using a vtr box!

    I think AlexBs car is the best pop/bang TU video ive seen.

    Pretty much the same as me. When my lambda sensor was broken it sounded like a gun everytime i changed gear. It does it now only if everything is hot.

    If you want pops and bangs, and it really means that much to you fit an adjustable fuel regulator and a fuel pressure guage

    Don't over do it though

    I read somewhere higher octane fuel can help with the pops bangs and crackles but is this not the case then?

    High octane fuel burns slower.

    In theory it's more likely to pop because it burns slower but it'll never happen. The key is getting it to run overly rich in order to pop and bang. this is why cars crackle and pop on over run, because the ignition briefly cuts and the injectors still inject fuel. the fuel ignites on the hot exhaust.

    Or just stop being a chav

    If anything it it was bad for my vtr.
    On 95 I get around 100 miles to 20 quid
    On tescos 99 I was getting 60 miles to 20 quid.

    With the money you save by getting 95 buy a 4-1 mani. Mine poped like mad when I had mine on

    i find when i get the cheapest fuel from certain supermarket petrol stations it bangs and pops alot more on over run , and the higher octane fuels from better fuel stations doesnt make half as much noise and just costs more. (i only buy higher octane when i have to for obvious reasons a 1.4 saxo doesnt need it)

    ive got supersprint manifold , supersprint decat center on to a 3" sportex back box if thats any help.

    Alot of companys e.g K-Tec do a Pop and Bang map for the Clio 182s so I'm guessing it means it runs stupidly rich on overrun like you say,

    Now now martin Chavs a strong word bit of fun through tunnels! would wind me up if it did it constantly! would much rather it be on demand rather than lifting off casually into any roundabout and its going BANGBANGBANGLOOKATMEBANGBANG! much rather it when giving it the beans when going through tunnels and the like time and a place

    Yeah Wayne mapped it at Chipwizards, currently running 181 at low boost (6psi) I'm running standard internals aswell, but forging in a few months when I've got some more coin
