Bluemalibu Posted July 28, 2015 Share Posted July 28, 2015 Paul, you'd be hard pressed to get better than Freak Show Performance converters without spending an additional $700 to $1,000. I was first recommended to use them from YellowBullet.com : "The converter it replaced was a holeshot 3600 B&M. With the B&M my 60's were all over the place (2.02 at worst to 1.87 at best, in one night, usualy 12.30-12.60et) when the sun went down, the swing was worse. I was pulling my hair out...With the new freakshow converter, off the trailer, it went a 1.79, and all 4 other passes were 1.79. The ET was the same: 12.389-12.399 (messing with shift points every pass) My MPH only fell off by .5, from before.I am more than happy with mine. I was worried at first (buying an ebay converter, and everyone quoting me $800-$1000 for a converter), but the guy hit the nail on the head with the stall. It was the best $320 I've spent..." They built a lockup converter with a 2400 stall for my 4L80E and had it delivered to my door in California three days later for less than $200. The Guys truly know their business and I am blown away that they can do what they do for such a low cost. Since I've had my converter, many of the guys from "Street Outlaws" have begun using Freak Show converters as well. They certainly top my RWHP by about triple.

silver71mc Posted July 29, 2015 Author Share Posted July 29, 2015 Hey guys thanks for the info. Talked to a couple tech guys from TCI and Coan, they think 2400 - 2600 stall speed will work well. Waiting to here back from Summit. What do you guys think? Thanks, Paul Quote Link to comment Share on other sites More sharing options...
Sam (Bones) Posted July 29, 2015 Share Posted July 29, 2015 I did a little research on the freaks how converters, I am very interested in them 1 Quote Link to comment Share on other sites More sharing options...
badddoin Posted July 30, 2015 Share Posted July 30, 2015 FWIW, I'm not particularly happy with the converter I got from Coan. I didn't call them, but I DID fill in all my pertinent information on their website, and they recommended a pro street converter for my application.It's wound too tight, IMO. It pulls hard against my breaks @1000 RPM. I will be replacing it in the future. Quote Link to comment Share on other sites More sharing options...
Bluemalibu Posted July 30, 2015 Share Posted July 30, 2015 The torque that your combo should be producing will raise a TC's stall a little Paul; and Comp themselves recommend a stock TC for the 11-242-3 cam. A 2400-2600 converter will put you well into the power range of this cam without generating the excess heat that a looser converter will produce. I would think that you'd be well served with it. I do not have any personal experience with either the Coan or TCI converters, as I was warned away from them by a few other driver's poor history with them... (including once by an employee of TCI) but, the bad rep certainly might simply be due to the fact that they sell a lot of converters, and so there will be a certain percentage that end up being junk. And those are the stories that get their dirty laundry aired. I went with Freak Show as I just didn't want to risk the chance with my built 4l80E.

silver71mc Posted July 30, 2015 Author Share Posted July 30, 2015 Badddion, a pro street is what they recommend I use also, that's a 2400 to 2600 stall converter, and it's trying to move the car at 1000 rpm. I don't know much about torque converters, but seems to me they got something wrong. Picking this converter has to be the worst part of this restoration so far, going to talk to freakshow performance tomorrow. If they say 2400 to 2600 stall is correct for my setup, which is just a mild street car, then I'll have to give it a shot, and hope for the best. Thanks Guys Quote Link to comment Share on other sites More sharing options...
silver71mc Posted July 30, 2015 Author Share Posted July 30, 2015 Ok, talked to Michael at Freak Show Performance. He knows torque converters, and it's not very often that you get to talk to the guy who builds your part. So, I ordered a torque converter today 2400 to 2600 stall. He said it will start to move around 1800 rpms. When the car is up and running I'll let you know how it works. Thanks Bluemalibu for the help.

silver71mc Posted July 30, 2015 Author Share Posted July 30, 2015 Hey Sam, that's what I was thinking around 2,000 maybe 2,200. Here are the numbers I got from the people who know. Summit # TCI-241501-A 1800 to 2000 TCI # 240900 2400 to 2600 Coan #20211-4 2400 to 2600 Transtar 2300 to 2800 Freak Show 2400 to 2600 Quote Link to comment Share on other sites More sharing options...
Its Just Me Posted August 1, 2015 Share Posted August 1, 2015 What did Freakshow quote for their converter? I run a Coan 2400-2600 and really like it. No issue with it pulling at idle and I get better milage than with the stock converter. I've heard really good things about Freakshow though. I'm interested in your feedback once your up & running.

silver71mc Posted August 1, 2015 Author Share Posted August 1, 2015 Scott, cost of the converter is $235 + shipping. Hope to be up and running by mid Oct. Paul Quote Link to comment Share on other sites More sharing options...
