the new converters are so efficient its crazy. that converter was built for his car knowing he is running a 3.23 gear. its not just an off the shelf thing like the old days. heck i was running a a 9.5" dynamic converter in my dart. it was a 3800 stahl. had 3.91 gears and i never took that ***** over 6000 rpm. i thought that was nuts when i was ordering it but shawn at dynamic told me it will be perfect. you know what. he was right. that thing worked and worked awesome. my car drove like a car with a stock converter on the street and when you nailed it or launched it at the track you felt like you were shot out of a cannon. its amazing how well the new converters. besides that 3500 number is just a generic number if its an off the shelf converter. tq of the enigine and raise and lower what it will flash and stahl at.

bottom line - ATI said the same thing... i'd burn up any trans / converter if i tried this.... you know what? they were wrong!

I called Dynamic and ordered a 9.5" converter built to my specs. I HAD a mopar 2500 converter in it before - 3.23's and a 2500 mopar converter, that acted like, well what you guys were saying, sloppy, and no mpg. I've had this setup for 4 years and over 7000 miles now...

I swapped and I am here to tell you that was the best thing I ever did to my car.

The efficient 9.5" dynamic GAINED me 2 mpg over the 2500 mopar converter,

the cruising RPM at 50 mph also increased 400 rpm - THAT is efficient UNDER the 3800 RATED stall - i was crusing around 2200 at 50 now compared to 2600 -

I went from 12.80 to 12.56 at the track for my best ET's - and 1.87 to 1.74 60' times improved as well.

there was NO area the old, 30 year old technology was better then the new dynamic 9.5" -

when you say i would be faster with 4.88's your probably right, but I wanted a driver as well as a drag car, and I can do 75 mph with this car for hours on end, and I do, and still get 16 mpg.

Alot of you guys still are stuck in the past with the way of thinking converter wise, Its a shame because there is alot of new technology you are missing the boat on!

I understand there is a lot of new technology out there and if your combination is working for you, great!

But I here a lot of people that are running a stall converter to compensate for lack of gears to keep the car streetable and that is not the way to go, that is what overdrives are for.

If your converter is stalling/slipping during ANY of the engines power range then that is wrong, you are loosing horsepower and performance. If your engines power range is lets say 2500-6000 you want that converter to be fully engaged by 2600 or the engine is producing power that is being lost in the converter and not making it to the rear wheels, you can have as much new technology as you want but if the converter is slipping/stalling even a little during the engines power range, you are loosing power. PERIOD!

That's all I am saying and I know some will disagree. Everyone has their own opinion which is what makes the world go around.
