Can someone give me a real simple explanation of the benefits of a higher stall converter. Inertia recommends a pushrod upgrade and a higher stall converter. I get the pushrods, but why would a higher stall converter be a must have? I have read up on stall/torque converters, but it seems that they would make the car have a very fast idle.
Any explanation would be appreciated.
Doug

Stall converters have nothing to do with idle speed and doesn't effect it. The way a torque converter (or stall converter) works is picture two fans facing each other. You start one fan and as it speeds up it starts turning the opposite fan facing it. The faster the first fan goes, the more pressure is forced to the other fan blades and causes it to turn faster. A converter works the same way except with hydraulic fluid instead of air.
The "stall speed" are the rpms it takes to were the secondary fins (trans side) are receiving enough force from the primary fins (engine side) to act as if there was a solid coupling between the two, as if you just let out the clutch. A higher stall allows the driver to raise the rpms higher before that direct link effect kicks in, thus getting the engine closer to it's power band for peck performance during acceleration.
Hope that helps!

Ahh...gotcha...so when they were talking about high revs at low speed, they must have been saying that your car with rev higher to get going versus at idle...
So Gordy, given that this seems like more of a performance benefit versus a "your gonna break your car if you don't have it", is there any reason that a higher stall/torque converter is "necessary"?

if i could chime in here, Gordon nailed that description pretty dang good!!!! i like that way to explain it as torque converters are one of the harder mechanical things to describe! anyhow back to me giving my .02, im assuming your looking at a new cam? so yes as inertia is advising you on this it is strictly a performance issue when they advise you of what else is recommended! you are not gonna break anything by not using a higher stall speed but you in turn will not see the full benefit of the camshaft! newer camshaft grinds change the RPM powerbands and there just saying with the difference in power range with the new camshaft you will see the most benefit by also adding a higher stall speed converter!

Gotcha...yeah, it is more of a money issue right now...want to get the cam going, but may have to wait on the torque converter as they appear to be a bit pricey...

i hear ya, i really wanna swap cams out as well! been considering the Inertia Crazy Spartan, possibly the spartan, huge gains even with stock heads, also a really bug bang for your buck!!! (well the cost of the cam anyway, not install!) gonna call around for install costs, gonna check with hinckley and also see if any of the group has anyone they recommend or hook-ups, cause the install is gonna be the price part!

Hey Doug, Travis (hemi5757) has honed his stock stall converter to 2800 -3k. He stated they use the current one and it cost him like $350 I believe. I will contact him and get some more info on it or have him post the information up. I plan to get my done as well, when I can get mine done all at the same time.

Thanks Chris, that would be cool. The guy that purchased my wheels has a shop out of Az. He is going to trade me parts for my wheels...He told me that he would install my Cam, TC and new pushrods for $500 if I bring my car to Phoenix. Dave at Hinkley said that it woudl be about a 16 to 20 hr install at $115/hr. That is some crazy money, so I think that I may take the guy in Az up on his offer. By-the-way, I ended up getting my Vipers for $160/wheel. about $25 for the lug nutz and then with mount, balance and tax I was out the door for just over $800!! There are some good guys over at the Lindon Discount Tire  |

There are some good guys over at the Lindon Discount Tire Doug, that is an awesome deal! When are you going to be heading to Arizona? ;D... I agree with ya on that price, the only thing, if there is any issues, which I am sure there wouldnt be, you either have to take car back to AZ or have someone local look into issue. Good Luck, keep us posted! Happy to hear your car is coming along quickly both visual and performance wise. Post pics of the Vipers ;D |
