Ok I haven't bought a torque converter in 15-20 yrs
I am lookimg for a 2400,2600 stall and came across the tci but I dont remember a 10" being 2400-2600 more like 3000-3500. And usually a 11" would give the lower range 2000-2600 but dont see any?
I hate to put the 10" and flash at 3000 plus rpm
anyone recommend a tc that is what it states?
Not a race car but a little street runner.

 

Contact Coan.

 

I recall reading that there is a converter core shortage, so the companies are using what is available to them. The old classifications of 10", 11", and 12" stall speeds are out the window.

 

ah, so a 10" could be a 2200-2600.. Im reading horror stories on tci convertor reviews. May call ATI. Up.

 

It's hard to say what the flash/stall speed is on any torque convertor The same convertor will stall different depending on engine size. The only way to get what you need is to contact a vendor and have it built for your car/specs. There's way too much guess work when buying an off the shelf unit. . The same convertor can be either a tight or a loose unit depending on how it's built. All 10" convertors do not stall the same.

 

I have a Hughes Performance 2500 RPM converter in my car. It's from about 15 years ago, so no idea if they're still the same these days.

what kind of cam set up do you have? And what stall from brake and flash stall??starts just looking at that

 

not sure who that is

They can build any converter you want. Call them, be prepared to discuss the car at length. Things like vehicle weight, gear ratio, tire size, engine modifications, etc. The more info you can give them, the better the converter will be.

 

Think for this application it be off the shelf 2400 stall

 

Cam is an UltraDyne .485” lift, 217/221 duration @ .050” lift. This grind was eventually bought by Lunati and sold under the VooDoo line.
The converter stalls to right around 2500 RPM.

 

thanks!

 

I contacted him, he gave me a price of 1150!
Off the shelf would work better for my application
its a contender.
thanks for the info

 

Not sure what you're putting it behind but be aware they offer some 'off the shelf' designs which are quite a bit less expensive than that. Not everything they sell is custom. I recently put one of their converters behind a new 455 build. Very impressed so far. Head and shoulders above the 10" POS I had behind the old 400G.

 

its a 72 H/O. With some modifications and cam.
I talked to Todd said a flash of 2400 may give me some idle problems and recommendations 1 off the shelf would work given a flash of 3k. Ati said the same. Ati stated a brake flash of about 1800 Todd would not say. Both are off the shelves. Its gonna be one of those for sure as both stated it will be most likely ATI because of past use
Definitely not going with a b&m or tci.

 

10" converters can be built to stall in the mid/low-2000s but it takes a bit of effort to make one that has good manners. A larger converter will naturally stall lower - more fluid, more fin area, more force, lower stall - but builders have advanced a lot in the past 20 years by mixing and matching different core components. The pump, impeller and stator can be mixed and matched (as long as they physically fit), and the fins can be modified, leading to a lot of combinations. Very creative things have been done like putting a 10" converter inside a 12" cover to use a 12" lockup clutch.
Custom built converters typically cost over $1K. The good thing is you'll get something set up specifically for your combination and most builders will modify the converter once or twice for free if needed.
I'm very fond of the TCI Saturday Night Special for an affordable converter that works well with mild builds. But it's been over 15 years since I've bought one so no idea about recent quality.

That was my go to converter with anti ballooning plate. The reviews I read on summit racimg on the tci converter reviews some splitting apart ,flashing 3800 rpm on a 2200-2600 rating its just to radical to take a chance on tci. My cam calls for 2400+ stall converter. My 1st thought was the tci 241101 break away tci with anti ballooning plate tci tech states ill get 2600 flash which is in the ballpark. Even if it goes to 2800 because of higher torque of the bb it would be even better. Is anyone using a tci break away out here?
