Launch control is different Mabz, all that does is slightly retard the timing to reduce the torque until the wheel slip is reduced to a defined percentage. The slip is measured by comparing driven wheel speed to that of an undriven wheel  ________________________________________ Contact Details:rich@lynxpowerengineering.co.uk 07732 822546 |

so launch is a bit useless if you have enough power to spin all 4 wheels  ________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

I think you don't need to use an anti-lag,I saw some videos of your car and it don't seems to need it. Your anti-lag is the GT28RS !! this turbo spools very fast! Anti-lag is just for big turbos or another especific uses. Turbo's durability is affected using anti-lag. |

Yep mainly for the noise, am not runing a big turbo, a gt34 i think from memory. Interesting to see what you can do with the car mind, learning lots of stuff.________________________________________ TEAM Supercharged Rallye |

gt34? when i had a look at yours USC it didnt look too big.. hence i thought it was a gt28rs..what power are you running? ________________________________________ Team Supercharged Gti-6NV Motorsport Automotive Performance Tuning 0121 448 7515 ECU Remapping/ DPF removal VAG/BMW Diag and Option Coding Peugeot Planet ECU coding/transponder programming etc www.nvmotorsport.com Facebook Page Project S6 |

doesnt anti lag works by dumping unburnt fuel down the exhaust, when it hits the hot compressor blades it combusts, hence the reason it fubars your turbos every 2 milliseconds. As said there is another few ways of doing it, in the wrc they have a bypass valve of somesort that puts a fresh airstream into the engine until the turbo is spooled or something... ________________________________________ 309 GTi6-T |

anti lag works by firing the coil packs, and/or injectors when the exhaust valve is open to keep the turbo spinning up between gear changes.Same theory as behind a dump valve so there is no stalling of the compressor wheel. Drastically reduces turbo life, but if not used every day it should be fine! AS for your management, i dont knwo if yours covers it, its often a feature of after market management, youll have to speak to the manufacturer. good luck with it chap, plus it sounds pretty coool!! ________________________________________ Going through the gates of Hell Backwards, in a ball of flames!I'll, save you a place!! |

You retard the timing so the mixture is still burning as it goes out of the exhaust ports, hence the huge increase in exhaust temperatures...________________________________________ - Bespoke rollcages/additions/adjustments.

Was running around the 350bhp mark until she blew, finally decided to get some proper conrods for her and do things properly this time, i dont expect as much power this time as boost has been turned down, would hope around 330bhp but the all important torque will be around the 380ft/lbs same as last time. Made a few mods with this new engine so she should be all good. I hope ________________________________________ TEAM Supercharged Rallye |

doh, course not, gearbox speed sensor would be traveling at the same speed as the wheels being read by the sensors....Darwin award goes to me!  ________________________________________ FORD PUMA: the gay car that will have the 6 in the twisties. |

what about turbo modifications to reduce spool up times?I've heard of people lightening the "drive" shaft compressor and turbine in the turbo and using fancy bearings etc. to get desired effects (not sure how much difference this will make if any). I think there is also various different compressors and turbines available with different blade/fin angles and designs to give the turbo different characteristics. As for anti lag try these guys http://www.wallaceperformance.co.uk/ they specialise in evos and scoobys but they wont turn down a challenge. They recently done the engine management system and anti lag set up on a pals evo 8. its running approx 530 bhp and has a fully forged engine. Its got switch able maps and the different maps include the antilag setup to suit. And believe me the car was fast before but now its astonishing. I think the antilag is set up with a direct feed throttle bodie which is electrically controlled and opens to a certain angle depending on the selected map. Antilag for the win! Except for the cost involved. As the costs are ongoing as service intervals are shortened. (so that's once a week on the evo now ) lol ________________________________________ |

If you like the noise just turn the ignition off when driving in gear and then turn ignition back on - BANG (ps i accept no liability when the manifold gaskets and exh valves die) ________________________________________ Team Ducati 7482003 Subaru Impreza STi |
