  1. Hi Guy's was just down at Motorsportsuperstore they mentioned. That they will be at Townsville 400 V8supercar round from 10th -13th July 2009 at 792 Flinders Street Townsville.. That they will be having a Clearance Sale. Trading hours will be 8:30am till late. Regards schockwavexr6t ps.I will going to the townsville event will pop in and check it out. They also mentioned that the are currently partnering up with clubs and forums to donate merchandise for there raffles and charities that clubs and forum hold. Heres the ad in the Official Program out now.. here's there link.These guys always have great bargins
  2. Well its a first an xr8 ute no turbos, no nos, standard cams run a 11.90 congrats to chris from Blue Power Racing Developments, good to see the 8 making up some rapid ground. should be interesting when he puts cams in it, lsl 1 boys watch out cheers
  3. I'm thinking the same setup has anyone else taken this path? Any other pics?
  4. a three inch mandrel bend is the same as twin 2.25 standard system you would be wasting money. If you are @ 300rwkws + then a exhaust change would be good to releaf back presure, then consider a 3.5inch mandrel bend system.. heaps more flow. just my 2c cheers
  5. philldub, me thinks you have hit the nail on the head thanks for feedback. So does cooler conditions extract more power as well? cheers shockwavexr6t
  6. yes interesting you mentioned to extract more power than the fuel can cope with cylinder pressure causes pinging. then why have been advised upgrading fuel pump isn't nessary only plenum and cold air setup?
  7. Hi philldub, yes this was back off during tuning which is great and a good safety margin, but what baffles me is that having to change plenum and cold air setup as I already have a larger ic will enable to get more power with out pinging.
  8. thanks for the feedback turbo6man, having said that so with my current mods I'm unable to go any further to extract more power without pinging as my tuner said knock test showed 305rwkws. so the only way to make more power is more efficent ic plumbing different plenum and ic this will stop pinging (pinking) and give me an extra 30rwkws right! sound like I have to send more money!!! cheers shockwavexr6t
  9. Or bad fuel, Sick of hearing this excuse from tuners what a joke <{POST_SNAPBACK}> Why? A fuel which has been sitting for a period of time will start to lose octane points, get moisture in it and be useless, or not 'optimum' As everyone always says, go to a servo who turns over alot of fuel. Why say this if there is no merrit to it?? Then there are the dodgey blokes who 'water' there fuel down with crap..... <{POST_SNAPBACK}> A car shouldnt be tuned to the point where if the fuel isnt 100% its going to ping its head off if a tuner cant tune a car without it pinging I suggest another tuner <{POST_SNAPBACK}> Spot on Adam <{POST_SNAPBACK}> Gents, Lets get one basic fact straight. ANY car with ANY tune will ping if the quality of fuel is poor enough. This is a fact. When we go to a tuner for a custom tune - the goal of this is often to maximise the torque and resultant power. I have had my car tuned (post Edit) by both HPF and Nizpro who I beleive are two of the best in the country (if not the best). In both cases my car was tuned using 98 octane fuel, and my primary maps were specifically tuned (at my request) for 98 octane fuel. There is a very simple reason for this - it is possible to achieve better power and higher efficiencies through more advanced timing. If I were to put 95 octane fuel in my car when running a 98 map - I would expect my car to ping from time to time until the knock protection retarded timing. If it didn't then the tuner has NOT done their job correctly. If you get a bad batch of fuel - then by rights the tune should be reflashed for one to cope with poor fuel, rather than relying on the knock control as this will only retard timing when knock is detected (ie already happening), or drive the car easily until the fuel is replaced. If the quality of fuel is poor enough - then the knock control will not be able to take out sufficient timing to prevent the pinging from occurring. More aggressive timing settings on our peak power 98 maps are obviously going to suffer from this with a smaller drop in fuel quality than a more conservative map. Bottom line is if you want a map that will be far more tolerant of poor fuel - expect less power than could be acheive with a more agressive map. This has nothing to do with the quality of the tuner, it is just a basic fact. As a specific example on my '98 octane' map my car produced 331rwkw, but with several degrees taken out for a '95 octane' map at the approximately same rpm and boost at peak power the car 'only' made 309rwkw. As consumers we just need to be careful about making sure tuners are not just using this as a blind excuse, but need to recognise that poor fuel will inescapably impact the performance of a highly tuned car. my 2c... Cheers, Ben. <{POST_SNAPBACK}> ben, that being the case when bad fuel is used to tune a car yes the end result will be a average tune. But if no bad fuel is used then timing is controled by tuner then the only other reason for pinging would be air density or presure drop through ic pumping or heat right. what I'm trying to figure out that if fuel supply is OK fuel quailty is OK and timing is controled by tuner whilist getting tuned then only other variable is air density. Does that mean that we are able to achieve more kws with colder conditions. so for example if you have achieved 331rwkws on a 98ron tune. So you decide to tune your car say on a 9 degree day I would assume you could get an extra 5-8rwkws due to air density. SO then you have say 339rwkws. What happens on a hot day say 36degrees you would lose some power and may start to ping? Does that mean your tune will need to be retuned or will the knock sensor kick and retart your cars tune and stop from pinging..... cheers shockwavexr6t
  10. does this mean tuners disable knock sensor when tuning a car to get the maximum of the tune. ie I Guess this would aply for people using the edit then activate knock sensor after tune to protect motor. Then why do we all need three maps with our edit's? Shouldn't we just need one tune! Tune the car to its full potention with currents mods ie 300rwkws then the knock senor will take over retart timing when needed ie bad fuel, heat,air density, why do you have to change tune maps to compensate for this? No saying 3 different maps is good? just curious cheers shockwavexr6t

  12. Hope some of the exprienced people have some thoughs on this topic cause I'm sure I will help others when it comes to getting the most for the cars. Is pinging,knocking,detenation caused by the following? Air density Fuel supply quality of fuel timing the reason I ask my car was pinging at 305rwkws and was backed of to 295rwkws is this due to lack of fuel or air flow or heat of the day begin over 32c. What baffles me is the next mod will be custom plenum,ic and different setup for cold air intake and no upgraded fuel pump required for setup as advised by tuner and will support 330 - 340rwkws So does this mean that standard ic plumbing, plenum and current cold air box stop tuners getting any more out of the current setup but with further mods pinging stops and more power is agained. That makes me think that changing the above will assist in air flow and less presure drop which stops pinging right. So fuel supply isn't the issue right! any feed back is welcomed hopefully this may shed some light to others and myself. shockwavexr6t
  13. great results tur and well done nizpro it will be interesting when you get your injectors done. cheers ps enjoy the new found power
  14. Great result, What mods have you got and what was your sixty foot time is it an auto or manual did you run it with street tyres.
  15. hi Goobz, car looks great,Bill mentioned that you picked up the injectors! Happy to help. I got a set of rims though I might post a pic as well.
