Teferius Posted September 16, 2003 Report Share Posted September 16, 2003 Well Tom Wright built me a trans with the 3.69FDR. I also have a 3000 stall torque converter and he is sending me the limited slip differential by sept 30th. So in October I should have it in my car. I was just wondering what can I expect from the 3.69FDR, from what I understand it will give me better acceleration on the lowend but Im sure there is more to it then that. I have really no clue about anything on transmissions. Just was wondering if someone could clear up exactly what will happen with the different ratio.

topless94style Posted September 16, 2003 Report Share Posted September 16, 2003 i dont know much about numbers either but if you got and this is for rear wheel drive, if you got say 4:10 your gonna have really really good low end. I dont remember what camaros got but they are 3:43?? its 3: something. Think of it like this, my friend had an S10 with a 385ci AT and 4:10 and he was cruising the highway with a 1995 Z28 AT. The S10 couldnt keep up because the RPMs where way to high at 90mph but he would smoke the Camaro off the line and possibly in the 1/4. The S10 i think did a 3-4 second 0-60 because of the gears. Thats the extent of my knowledge and tahts on rear wheel drive im sure someelse knows more. Quote Link to comment Share on other sites More sharing options...
Bolt_Crank Posted September 17, 2003 Report Share Posted September 17, 2003 a gear ratio is a gear ratio, no matter what drivetrain layout you have... Quote Link to comment Share on other sites More sharing options...
Teferius Posted September 17, 2003 Author Report Share Posted September 17, 2003 Well does anyone know what to expect from the stock FDR of a 3.4 4t60e auto to the 3.69 FDR? Quote Link to comment Share on other sites More sharing options...
Bolt_Crank Posted September 17, 2003 Report Share Posted September 17, 2003 well.... if the # is bigger than stock, it's gonna have more acceleration, but less speed, if the # is smaller, it's gonna have less acceleration, but more top speed Quote Link to comment Share on other sites More sharing options...
Teferius Posted September 17, 2003 Author Report Share Posted September 17, 2003 Okay thanks for putting it simply for me. Quote Link to comment Share on other sites More sharing options...

Robby1870 Posted September 17, 2003 Report Share Posted September 17, 2003 Well, going to 3.69 is not that big a difference from the stock 3.43 in a 4T60E mated to a LQ1. You'll get a little better acceleration, but turn more rpms on cruising on the highway. Robby Quote Link to comment Share on other sites More sharing options...
slick Posted September 17, 2003 Report Share Posted September 17, 2003 well.... if the # is bigger than stock, it's gonna have more acceleration, but less speed, if the # is smaller, it's gonna have less acceleration, but more top speed Couldn't have said it better myself.

Vegeta Posted September 17, 2003 Report Share Posted September 17, 2003 I know 2 people with 3.73 FDR, one is a dohc and the other a suped up 3100. The 3100 took to the new final drive much better than the DOHC, as in more noticable. Probably because of the low end the 3100 has to begin with.

Mike J. Posted September 17, 2003 Report Share Posted September 17, 2003 Sounds like a great setup and choices. The 3.69 is not a huge amount of differece but just right to get the DOHC into its initial torque band and then horsepower curve. The 3000 stall converter is pretty stout. You'll need the limited slip since it will send the power to both wheels, otherwise you would probably spend all day frying your tires. If you still fry tire too easy, you may have to get wider and/or very sticky tires. Quote Link to comment Share on other sites More sharing options...
Teferius Posted September 17, 2003 Author Report Share Posted September 17, 2003 Well I have 245/45/17 Toyo Proxes T1-S Tires... very high rated tire. They grip very well and I get very little tire spin ever since I put them on. Quote Link to comment Share on other sites More sharing options...
99RegalGS Posted September 18, 2003 Report Share Posted September 18, 2003 The LQ1 has a 3.43 FGR! Thats quite a difference from my 3800 regal with a 3.08 FGR Quote Link to comment Share on other sites More sharing options...
