A340E 2500 Stall Coverter $450?

[born2drv]

What do you guys think, is this a good deal? They said it would be good for 600hp no problem.

Company is caled Hughes Performance. Anyone have good experiences with them?

Price is $450 with a core. Is that a fair price?

I won't be pushing the tranny much more then 400hp, and only on rare occasions. I don't often step on the gas too hard

Thanks.

The stock converter is about 2500 rpm...why replace it with the same stall?

 

[born2drv]

Are you sure? They said stock is around 1700-1800rpm. I inquired about a 3000 stall, they said it woudln't fit the stock housing and they'd have to get a custom made one, and it would be double the price or more?

If I really need higher then 2500 where can I get it from? Who rebuilds them?

Thanks.

The stock stall is 2500.

So where does everyone get their high stall converters from? How much?

 

[tubbie]

the converter may be good to 600hp, but the tranny sure won't make it there.

yep it sure is. some are more loose than others, but it is in that range.
as far as 3000 not fitting, thats crap too. i have a 3400 in mine.
the cheapest place is an outfit down in florida. i'll see if i can dig up that info for you or perhaps someone who know's what im talking about will chime in. iirc they were less than $200 for a mod'd stocker.
fwiw i got mine from phoenix hard parts for $400.

also to note, you might want to drive someone's car w/ a higher stall converter. the car behaves a lot different and may not be something you are looking for.

 

[born2drv]

how does it behave differently? basically the car will output higher torque up to the stall rpm right? so does that make it more jerky?

will getting a higher stall coverter help the transmission last longer in any ways, or is it just a method of obtaining more jump off the line?

best way i can describe it is it behaves like driving a 5sp w/ a slipping clutch. you have to give it more throttle to get the car moving, less responsive in normal driving, and climbing hills you have to really get into it. just driving my car onto the trailer wasnt a lot of fun. you have to give it quite a bit of throttle and it goes up the ramps at around 3600rpm. on the highway, thats different too. if you are cruising along and put the hammer down it will jump up to 5k rpm and just sit there until the road speed matches the gear.
now, launching, its an animal. i can spool up the turbo and launch up much higher in the rpm. it comes out of the hole something crazy.

as far as making the tranny last longer, no. it produces more heat and will kill the clutches unless you have a good sized aftermarket tranny cooler. regardless of the stall, thats a good idea anyway.

Mine has a 3000 stall...less of what dbsupra90 experiences above. It's still responsive in normal driving, but allows me to rev to 3000 rpm and get the turbo spooled for a launch. Here's something to think about...when does your turbo spool? You want to match the turbo to the stall as close as possible. Also, is this a daily driver? As you can see, taking the stall up to 3400 makes a big difference on how the car drives in day-to-day traffic. I have an air cooled tranny cooler with a Spal fan on it....a tranny cooler is an absolute necessity if you want an auto to last.

One other consideration for an auto tranny...you go over 350 HP and the stock tranny will toast. The clutch plates can't handle it. You have to have the tranny upgraded with friction and valve body mods...it's not cheap, especially when compared to swaping to the 154 tranny.

OK well I bought a TC61 Turbo ... this is what they say is in the turbo:

"Custom compressor with 61mm inducer, custom p trim turbine, 360 tied-down thrust washer, large shaft .84 turbine housing with t3 footprint and divided scroll, and .70 compressor housing. Polished and Ported. Dual piston ring seals for oil control and a dynamic seal for the compressor side."

I'm assuming I'll get full spool around the 3000-3300 rpm range?

I bought a B&M 8x11x1.5 cooler for the tranny so hopefully that will be enough, haven't installed it yet.

I really don't intend on driving the car hard at all. Most likely I'll be babying it for the next year or so until I get all my little issues resolved, then I'll be building a much stronger engine and getting a built tranny put in.

I have been looking into gettin a HSTC as well. It's weird because off the line, if I hold it at 1,500rpms, (obviously), I'm not boosting, and it wants to start spinning even then and boy does it go. If I take it past anything over 1,800rpms, it starts spinning.
For turbo spool, it starts spooling at about 2,700 and by 3,200rpms, I am at full boost(about 12psi in 1st gear). So...you are saying that "I" should go with perhaps something of the 3200-3400 range?...and some good slicks, lol.

import performance transmissions has high stall converters, shift kits and whatever you want for toyota performance.

anyone know where the place in florida is? i live in the clearwater tampa area and im in the market for a 4.30 rear end.

You guys got the idea

I bugged Larry at SP to no end until I was satisified the SP61 Turbo was going to meet my objective. I was looking for a quick spool with good high end power. For me, I went with a stall at the lower end of where the turbo starts to spool...I didn't want the drivability issues alluded to above.

IPT makes a good stall converter...I've got one...along with the rest of the package. Avoid Level 10...I know several guys that had issues with their auto tranny builds. I believe SP is also doing auto tranny mods/converters.

 

[dbsupra90]

turbo spool is one way to do it, but ideally you want it at your torque peak.

as far as drivibility issues, it just depends what you want the car to do and what you expect out of it. there is always a compromise of some sorts. i really dont mind it and may have made it out to sound much worse than it is. but it def isnt for everyone. thats why i suggest someone driving one to make sure if at all possible.

 

[suprarich]

My stocker stalled at 1800 rpm, two other autos i have owned never stalled above 2000. IPT as mentioned above did my converter to 3400-3600 range. Great company.
