Convertor woes

[Anonymous]

Got the 9 1/2" 3000 stall dynamic covertor which was originally fitted in the ole 440 , this convertor used to lock up on footbrake around 3200rpm , using the same convertor behing the 605" , used to stall @ 4500rpm with the 4.10 gears , changed out to the 3.23s & noticed it slipping even more , the 'punisher' ran the 1/4 without a change in engine note , this convertor is now stalling (footbrake) around 5200rpm .

I'm thinking on changing the convertor out , maybe this thing is going bad? , gearbox fluid is still nice & red.

Any ideas chaps?

err, its big engine with lots of torque

I'll get me coat....

I realise that Pete , i'm just thinking if i'm leaving any power on the table , be even worse with the sniff , probably blow right through it.

Anyone got a convertor?

Your speed doesn't appear to indicate a serious conv problem.

[Guy]

I pulled a mph pb the day my converter packed up on the way home from shakey.

Adam, one for Blue or Dunc,
your MPH is down just a little on other cars running similar times

why the 323's, and is the GV playin any part in this to ?

Maybe its the box slipping not the convertor ?

Maybe because the Monster has such a wide torque band, it just appears seamless ??

:Don't think going from 4.10s to 3.5s is going affect your stall speed?
Big stall convertors around but noo good for street use. Custom build is the only way, with balloon plate

Been thinking about this , the convertor is a dynamic dual stall , maybe it's doing what it says on the tin , even the ole 440 kept the same engine note down the 1/4 , maybe there's nowt wrong with it.

i never read the start off this thread proper punisher maybe it is ok and just keepin the mtr on the boil if it launches hard and the mph is about right at the big end then it seems right

Should of said it was a dual stall but forgot it was a dual stall , anyhow ,apparently no one knows anything about these convertors , so will just see if it holds up.

"on the boil" , like that. , as long as it don't boil me tranny.

I have an 8" Dynamic, which was 5500 stall but i've just had it tightened as much as poss, which i believe the most is around a 1000 rpm.
You are welcome to try it and if you like it then we can sort a price and you can pay me for it when you can afford it.

Thanks Mick

The one i have was stalling @ 3500 on the 440 , not sure what you're one will stall @ on the 605"? , if it's been tightened say 1000rpm to stall around 4500 then not sure if i would be any better off.

Thanks for the offer Mick , might need it.

Brutal me old mucker, I'm considering a dual stall converter, so that the Barracuda is okay to drive reasonably well on the street, but will perform at the track...how does yours actually drive?

I listened to your engine note when you were racing at the Pod the other week and as Duncan said, it seemed to act like a centrifugal clutch and kept the engine on the boil, but your speed increased.

After checking out the web I can't find out anything practical or constructive about these things...
