Firstly there is no such thing as a "stall converter". Second, that's pretty high stall speed. Is this a street car? |

sorry im new to automatics but you get what mean,
and yes it is a street car but not a daily driver, what would be a good stall speed and price, the car is making 384rwhp if that makes a difference |

Well it's up to your tastes and needs but IMHO a 3500 stall sucks major ass to drive. I personally wouldn't put a high stall in a daily driver at all. Centrifugal blower? |

I have a ~3500 stall and it isn't bad to drive. But I also have a single turbo so it keeps it near boost.
I thought one of the good points of a supercharger is that you don't need as high a stall? |

yeah its Centrifugal(vortech V2), and i just want to get some good times at the drags, its just too heavy to get off the line, so far i could only manage 13.247@110.88mph |

How's your traction? |

if its too heavy then lose the back seats, get some lighter front seats, cf/fg bonnet, trunk lid, lighter wheels, rip out the carpet etc.. |

Yeah, theres a good 100kg's+ that can be taken out of a 31 if you want to give up the air suspension along with other luxuries, depends what you want to do with the car but if your after a high stall TC then sounds like performance comes 1st over comfort. |

13.25 is a damn fine time for a luxury GT! I'd be pretty proud of that! Hell, thats as quick as an M5 isn't it? |

If your traction sucks then a high stall isn't going to help |

I can do a 14.819 on 215/45/17 semi slicks and all my engine mods I have done is disconnect the air flow sensor and a full exhaust also I have swapped the front seats for some Jamex recliners. A Hilux that is constantly there does high 12 second passes I think and that has a Eaton M112 with a FMIC. I would say first try running on some better tyre's and then perhaps make it a little lighter. You are probably doing fine with your current set up but if you did whats been mentioned you will surely see high 12's. |

110-111mph should yield a mid 12 sec quarter, mate. you just need sticky tyres. By the way, to answer your question, $1500 is WAY too much for a stall convertor. Only pay half that much, at tops! |

First thing, have you got a shiftkit and trans cooler installed?
if not read no further until you do, the stock box will not last long without it with the power your making.
Before Changing the converter get some Mickey Thompson ET streets and just practice your launches more. The extra grip from the MT's will make a massive difference and make it so much easier to get off the line.
To get a good launch use both the foot brake and handbrake, don't worry about rpm too much just make sure your making a few pounds of boost before you release the brakes.
What was your 60ft time for that run? |

My best 60 ft time was 1.68,this was with the standard stall. I have a 1.5 MV Automatics shift kit and a 3200 stall, the problem now is that I'm getting wheelspin of the line even with the MT's. As the others have said, get some MT's and stall it to about 3000 rpm and there is no reason you cant get a 1.7 60ft time, that should drop your times by nearly a second overall. |

Yeah I also ran a 1.68 60ft with stock converter with MT's.
Unless your running full slicks the higher converter will only cause wheel spin.
Do the V8's run the same converter as the TT? |

To be honest a 60ft time like that is horrible. On my 14.819 time(pb) my 60ft time was 2.208. If you have forced induction it should definatly not be any where near 2.301. Check my profile for list of mods done to my car. Perhaps a bit of traction issues for you or too much weight but you should not have 2.3 second 60ft times. |

That 14.8 isn't to flash either, my stock TT did a 14.3@ 96mph with a stuffed turbo and just a 3" exhaust.
It just comes down to practice and its even harder with a small capacity TT motor as if you don't get enough boost off the line it will just bog down, too much boost then it just spins the wheels.
A 13.2 is still a very good time when you consider that most of the VE SS commodores with 317kw often run just under 14sec passes. |
