Hello,
I was thinking about posting this into the transmission & drivertrain forum, but i guess here is the place where i will get some more appropriate answers to my question.

Iīm searching for a new torque converter for my `85 Camaro 2,8l automatic. Searching in a significant number of online stores didnīt helped me in my quest. In fact, i need a converter with a higher efficiency than the stock one, because the engine isnīt exactly the strongest block on the road, my goal is to let as many of the engines horsepower as possible through to the rear wheels (and maybe get a slightly decrease in fuel consumption). When i look in the stores, is only see expensive racing or drag converters, which would be totally oversized in my ride. Even though there are some power adding projects planned for executing next year, the total output will be very unlikely to become more than 200hp, so there is absolutely no need for install some high-performance converter which would be able to handle 500+ hp!

I hoped that some of you guys could name me a vendor who offers a nice converter with increased efficiency for a reasonable price.


Oh, and due to the fact that here in germany vehicles with automatic transmission are still as rare as natural DD ****, i almost got no clue about the tech stuff behind it, so could someone please explain me what the term "x000 rpm stall" is meaning?

Thanks.

 

well for one since u have a stock engine and are just looking for a lil better pickup.id either go with a converter out of a v6 s10 pickup,since it has a lil more stall speed then the stock camaro one.this is ur cheapest option.or u can buy one from here
Precision Industries - Vigilante Torque Converters
the one on the very bottom
9.5" lock-up V-6 Camero/Firebird
Single Disc
2400-6000 RPM's
since ur engine is stock,i would sugest no more then a 2,200-2,400 stall speed since the 2.8 makes most of its power down low
i would say the best overall option u have would be to install a set of 3:73 gears in the rear

Torque converter stall is a commonly used term and is commonly misunderstood. Stall is the speed at which the converter will hold the engine speed and not allow further gain (i.e., the engine "stalls"). The key word here is engine. The speed at which stall occurs with a given converter is a function of engine peak torque. It is clear that the stall speed on a given converter will not be the same coupled to a tame small block engine when compared to a big block with all of the muscle features added. When comparing stall speeds it is important to account for the engine that drives it. True converter stall can best be determined when a Transbrake is used. Testing for stall value by locking the wheel brakes generally does not produce a true stall value because the engine power can often cause wheel turn by overpowering the brakes. Stall speed determined by this method should be identified as such when discussing stall speed determination. Flash stall is determined by launching at full throttle and observing the peak speed attained at launch. Selection of the right stall speed for your vehicle should be matched to the engine peak torque, engine torque curve shape and vehicle weight. In general, the stall speed selected for your converter would be 500 to 700 rpm below the peak torque. This speed allows the margin for application of the torque reserve on takeoff. When selecting stall speed without having prior experience to go by, it is better to conservatively estimate the engine torque than it is to over estimate it. If you over estimate the torque output you will have a converter with a stall speed too low, making your car slow off the line and have slow ET. A properly selected stall speed will give you better launch and better ET.

though there are many aspects of the engine that will affect actual/vs advertised stall speed

take mine for example i bought one that was said to stall at 2,600 well before i had the turbo on my car i could only get it to 2,300,now that i have the turbo and the engine makes more power i can stall it upto 3,200 rpms

 

I like my convertor it stalls about 3000 on a stock '89 2.8l. I am not sure what it was origanlly for but I believe it was for a 2.2l s10 with a 4l60e trans. I got it for free out of a core trans that was brand new. Mike
