  1. way cool man...will add some details later
  2. i have done it...see the Forced Induction sectiono under RB25 turbo upgrades stickey for some more details. I had issues, which turned out to be my stock ECU which if u looked at the graph you can see. I also have it for sale on ebay at the moment. I ran it to 250rwkw. I would say, if you already havn't got an emanage just get yourself a PowerFC. Its less installation cost and better in general.
  3. lol SAU dating thread...ASL?
  4. hotter was bad word usage...hotter in comparision to a turbo without the insulator as it just radiates heat...thats why you might want a shield and the initial question. nothing to do with temp? when the gas expands and cools down...where does the heat go? in fact what do you think the heat is used for? ...its no suprise it expands..its deisgned to do it. The gas will be cooler...but thats not the aim...the aim it to turn the turbine using, partically, the heat generated during the process. You seem to have some idea...so do you want me to go into the relationship between Heat/Pressure/Volume? we have sort of covered it...all of these are used to make the turbine spin. Its fact,mate...designed many years ago by people smarter than me and I even looked it up in my old physics book to be certain. In short, gas temperature, pressure, and volume are all related. Compress a gas (reduce the volume) and pressure and temperature goes up. Let it expand, and temperature and pressure go down. Increase the temperature, and the pressure goes up (in an enclosed space) or the volume goes up (it expands). Finally, gases want to flow from a high pressure area to a low pressure area, and the greater the difference, the bigger the push. (Pop a baloon, little bang. Pop a welding O2 cylinder, big bang) read up on the The Ideal Gas Law. then relate it to the otto cycle in a 4 stoke engine...it will answer the aparent mistery.
  5. off the piss?
  6. Centreline Suspension.....the place to go...
  7. It is a common misconception that the exhaust turbine half of a turbo is driven purely by the kinetic energy of the exhaust. While the kinetic energy of the exhaust flow does contribute to the work performed by the turbo, the vast majority of the energy transferred comes from a different source. Exhaust exits the cylinder at high temperature and high pressure. It gets merged with other exhaust pulses, and enters the turbine inlet - a very small space. At this point, we have very high pressure and very high heat, so our gas has a very high energy level. As it passes through the diffuser and into the turbine housing, it moves from a small space into a large one. Accordingly, it expands, cools, slows down, and dumps all that energy - into the turbine that we've so cleverly positioned in tho housing so that as the gas expands, it pushes against the turbine blades, causing it to rotate. The amount of work that can be done across an exhaust turbine is determined by the pressure differential at the inlet and outlet. Higher outlet pressure, lower pressure differential, less work, less boost...hence why we like to wack on better free-flowing exhausts. So why a blanket...my assumption is to get a better temp. differentail accross the inlet and outlet...for the reasons stated above and keep the gas in a high energy state..why?? for any1 who has done basic physics you can answer that one!
  8. the turbo blanket insulates the exhaust side to retain the heat.. this has two benifits...reduce engine bay heat (although its probably quite hot anyway) and reduces radiation loss from the turbo...why? turbos work on heat and pressure and the conversion of kinitec energy to make the turbine spin. Once well known example is wacking on a 3" zorst.. it gives greater pressure delta and allows quicker spool and more boost total...as heat is also another important energy source...keeping the temp high in relation to the zorst temp helps produce a greater pressure difference and hence more flow..more flow..more spool..morse boost...anyway thats my basic physics understanding from the top of my head...so correct me if i'm wrong some1. But i do notice Garret for example warn against use of the blankets in garage enviroments for BB turbos...not so much for water cooled ones...not sure what they are on about exactly. te one of these.... http://www.horsepowerinabox.com/HPIAB2/category60_1.htm
  9. the only good theroy I have heard thus far is the beenie to keep the hot side hot...i.e. greatest heat/pressure difference - afterall thats how turbos work.. I had my shield removed and was thinking about what to replace it with...I was thiking a shield..maybe a bennie? where can u gte these from?
  10. haha thanks man...it didn't make any noises...so I thought I was cool. Just in the Castrol spec sheet it says not for LSDs...but the stock R33 diff is a viscious LSD and aparently this is still cool...but I'm still not sure about that.
  11. yep just take it off and have the bearing replaced...about to do mine. easy fix..
  12. hey trex and busky2k I'm getting confused with the diff oil...read stuff about it and thought i was cool... Castrol Syntrans and Syntrax..75W90 I think they are spec'd at. I have a stock s1 r33. I used Syntrax as it was GL5 rated oil...wondering if I should have used the Syntrans..I get confused with them..Its not for LSDs and I have no idea if I have one or not lol I guess I should know. KJ
  13. ya couldn't agree more...crap rims...using spacers i.e. all load on the studs hence they snap off... Work/Rays rims FTW

  15. bilstiens ftw got a new setup all round with matched springs...u need these but not cheep.
  16. probably something to do with ur PFC tune...can't rem. the details but mine is lumpy also on idle was told why and it had something to do with the cells at that rpm...
  17. I'm not sure what the issue is, more power eariler..then why are u suprised it makes more torque earlier considering they related.
  18. 26 omfg...nearly feaked me out more than when Mav told me he was 21.... happy bd dood.
  19. khunjeng

    Leaving Job

    7 weeks OMFG!!
  20. khunjeng

    Defected!

    there is no issue if u cut in the correct spot. as suggested in a few spots...
  21. is cat temp sensor does it...usually is tucked away when they install an new hi-flow...u sure its not the engine light? i.e. excessive knocking?
  22. 5Zigen GN+ ftw....nice looking rims.
  23. arh the cop shots....that cop guy was right into it once you got him going...I watched him go to the next stand and get some more pics lol I want the video...
  24. lol ALL GTR less shots in front of RevZone and more with hot chicks...its autosalon man! with that turbo u should have plenty of chicks lining up...hehe
  25. I'm only voting for some1 who puts a higher priority on SAU swingers nights...I havn't had one since I joined...I was promised heaps??
