Anyone using the S-10 Torque Converter? Just wonderin cuz i know the S10 TC is pretty popular with the 94-96 Impala crowd but i havent heard of any F-Body owners usin it.In the Impala,the S10 TC stalls around 2200RPM and from what i hear,is a real cheap mod.I was just wonderin what RPM it would stall at in an F-Body since the B-Body has a bit more TQ.Thanks!

I think I've heard of people using it, but I'll let someone with more experience speak up. But for the time and effort, you could go with the SLP 2400-2600. Or that matter a Vig2800 or Yank 3000.

I had it before my trans took a dump when my car only had the stock motor and 4.5 # of boost from the supercharger...Now I am running a 3000 Vig converter.

The S10 was a pretty sweet converter, It was a bargain pricewise and it stalled about 300-400 over stock. I dont think my trans took a dump because of the converter but It finally gave up because of old age, I had 101K miles on the tranny before it died and about 22K with the S10 converter in it. I really like the difference that S10 converter made, It definetly had a nice seat of the pants feel to it but I never got the opportunity to take the car to the track to see the difference it really made. If you want feel like spending 400+ bucks for a new convertor and or only want a few more hundred rpms stall over the stock converter, I would highly suggest using the S10 converter.

Hope that helps,
Claude

This sounds like a nice deal as I suppose a guy could steal one of these at a bone yard. What is the factory stall on a 97 Z? Look forward to more intel on this. Shawn
Allways looking for a CHEAP way to go faster!!!!

You can also get the s10 restalled to different speeds VERY cheaply if you want. lt1dave.com sells the s10s restalled. Biggest thing though, they dont increase your STR, and if you hit them REALLY hard (1.7 below) on slicks they will likely balloon.

ALTJAR, what do you mean by 1.7? and STR?
Thanks Shawn

I was talking about 60' times with the 1.7 number (should have been more specific).

STR = stall torque ratio. Each stall is rated with a STR number. When the stall flashes at its stall RPM, take that number, times your TQ at that RPM, and thats what the stall will out put to ground. Its a torque multiplier.

This is one of the reasons you see large spikes in A4 dyno graphs when you first mash the gas.

I think the stock f body and s10 stalls are 1.0 STR, or a tad higher. So they dont multiply the torque much (not sure on stock number).

The higher end vigilante, yank etc convertors offer 2.0, 2.5, 3.0 STR etc. If you have a 300ft/lb car with 3.0 STR stall, it hits will 900ft/lbs of torque. Cool stuff

So what you are saying it's better to just buy a yank or the such? Thanks again for helping me get my covers from DJ. My car has the usual bolt ons.

dont higher STR's TC's slip more too? Most factory cars stall in the 1400 range (except stock 4 cyl. cars,they have higher stall TC's in em cuz they have no TQ,so if they didnt have a higher stall, it would feel even CRAPPIER than it already does)

No problem, i knew that would be easily worked out

It all comes down to cost and goals. You can get the S10s for about 300 bucks, which includes the re-stallinh. Thats great if you need a stall just so you can run a cam. You will gain from them becuase you move the stall speed higher.

The nicer stalls are 700-1400 bucks (can get a really nice off the shelf vig for 700ish, lots more for "custom"). These are the stalls which you gain 1/2 second etc from. MOve up the stall speed same as the others,, but they multiply the TQ much better.

I was running a restalled S10 converter before I bought my Vigilante. Pros and cons:

Pros...
1. It's cheap as hell.

2. It works fine as a stock converter replacement.

3. You can pull off a decent 60' (1.7x) with it.

Cons...
1. It's very "sloppy"...especially compared to the Vigilante. Driving below the stall speed (typically around 3000 RPM for a restalled one...depends on gearing and engine mods) sucks. Basically, there's hardly any torque transfer under the stall speed.

2. It won't hold a ton of power...once you start making good power, you'll have to start worrying about breaking it.

3. That good 60' I mentioned above...you'll only do it once. I pulled a low 1.7 60' with a set of ET Streets and a stock 10 bolt. On the way home from the track, I noticed a funky "whirring" noise. I ignored it for the time being, but it got worse and worse. Turns out that I had destroyed the bearing on the front of the converter (pretty sure that's what it was) and it was eating itself. This was all after my 383 went in though, so I doubt a mildly cammed engine could destroy it.

4. The STR sucks compared to a good converter (Vigilante, Yank). I think the S10's STR is around 1.1...the Vigilante is around 2.5. It makes a huge difference in the way the car launches and also feels much better just driving around.

Bottom line...if you're still fairly stock, or you're looking to cam your car and need a higher stall converter to avoid surging, the S10 converter should work fine for you. If you have the money though, I'd recommend a Vigilante. The Vigilante is much more efficient below the stall speed and it just plain feels better when you're driving it around. It's a lot of extra money ($400-$500 more than the S10 converter), but it's well worth it.

What is the part number of the s/10 torque convertor that is a few 100 rpm's above stock.

The part number is 24202310...you can find it on http://www.gmpartsdirect.com. Be prepared to get raped on shipping.
