Re: Automatics .....Gear Upgrade (SteveElliott)

I have decided on a 3.42 Carrier from GM and currently undecided about a TC at the same time. (See other post on TC) I hope to have the Heads CNC'd this coming year and maybe a cam. Until the warranty expires or until it becomes a weekend ride (currently daily driver) than I am hesitant to go all out. Of course....Lotto withholding !! :lol: :lol: :lol:

Thanks for the reply, guess I missed the nitrous in your sig :crazy: I see it now. You make some pretty good points here, gessh just when I thought I was closing in on a decision!!!! Your buddy's car sounds pretty nasty must scream on the highway @ 70 mph.

I went from 3.15's to 3.42's until better gears were available. I then installed 4.10's and have no problems with driveability at all ! I use the car as a dialy driver with all the components as in my sig.

I have the 3.42s and for the money and performance this setup is the best in the business...

I have an A4 and I went from the 3:15 to the 3:42's - big difference - big - gas mileage was hardly effected, pick up & standing start is much much better - I calculated that I'll lose approximately 8 MPH off top end ... I would do it again in a heart beat ...

Hey Topless,

I get the benefits of a reduced weight t/c, but what's the story about the diameter?? I've read diameters ranging from 9-1/2" up to 12" - what's up with this? Is there a more beneficial diameter? What's the factory t/c's diameter?

Time for a lot of generalizations. :D Typically higher stall converters weigh less and have smaller diameter. Larger diameters typically hold more effectively. You end up trying to balance holding capacity and efficiency against ability to spin up quickly and multiply torque. That's why this line looks neat, it's less of a compromise (but expensive as converters go, although right in line with other high tech converters.) I'm not sure how big the stock converter is, I'm vaguely recalling it's like 12" or so. It's definitely big and heavy. :cry

I've said it before, I'll say it again... I wouldn't stall a blower car the same way I'd stall a NA car. I also wouldn't run track events with a car that has a big dumb drag converter (i.e. loose with lots of shift extension) in it. Converter choice is all about understanding what and where you want your throttle response to be like. If I were building a setup like yours and committed to the blower I'd be looking at something like Yank's PYE3400. But that's just me. :)
