Moderators LWARRIOR1016 Posted July 28, 2017 Moderators Report Share Posted July 28, 2017 Ok so I just finished up my teksid 4.6/4r70w build. I put it all together with a converter that was ordered through transtar. It was a custom built unit that was supposed to stall at 3500rpm.....well, it doesnt. I might see 2200 rpm and its unbalanced as can be. So Ive been searching for torque converters. I know all the big name companies, but I came across Roadrunner converters in Arizona. They seem to have a pretty big name and put a lot of videos out on the web so people can see their facility. I couldnt find many reviews from a performance aspect so here we are, Im trying one. I just ordered a 10" converter 3600 rpm stall. Should have it here next week. I will be sure to let everyone know how it works out. Link to comment Share on other sites More sharing options...

D3vst8r96gt Posted August 3, 2017 Report Share Posted August 3, 2017 I have one and so does my buddy. Can't go wrong, great customer service too. Answered all my questions.

Thats awesome, real world experience. What do you have it in and what kind of stall is it? Sorry about playing 20 questions, it just seems like everyone is scared to run them and keeps saying, "you get what you pay for" or "I would just go with a bigger name company". Not many people have anything to say in general about them. Link to comment Share on other sites More sharing options...

I replaced this one with a 6 puck clutch that didnt have any dampers and it would have help up but I blew the engine up a week or so later.

Not many people have anything to say in general about them. Get a transcooler, I changed my shift points and lock up to keep temps down but it is added insurance. Its a 4300 stall and its just a stock pi motor (not the greatest set up) its suppose to have a built 3v infront of it but that project was halted when my brother blew my motor in the '96. But I think I have killed my tranny as it slips when cold now after a few a years of daily driving it. Probably not a reflection of the converter, Its a huge stall with stock gears lol Illl ask my buddy he has a more normal stall. He daily drove his and made lots of pass as far as I know no issues. 1 Link to comment Share on other sites More sharing options...

Awesome. Ive got a trans cooler with a fan on it and have the transmission wired and shifting controlled by a microsquirt stand alone. Also have 4.10 gears and a not so stock 2v. The 3600 I ordered should do alright. I really appreciate the feedback as I was a little nervous about the torque converter to start with. Mine should be here today (along with the 4000 stall PATC converter I accidentally bought). Im going to run the roadrunner converter first and see what its about. With your 4300 stall, how much are you getting out of it, and how does it drive on the street? Is it real loose feeling or is it kind of tight until you flash it?

Moderators LWARRIOR1016 Posted August 5, 2017 Author Moderators Report Share Posted August 5, 2017 Got my converters today. This is the one from roadrunner. 10", 3600 stall. So far I'm pretty pleased with all of it. I should be able to get it installed next week. Link to comment Share on other sites More sharing options...
droptoppony Posted August 5, 2017 Report Share Posted August 5, 2017 Never heard of them but that doesn't mean they aren't good. I picked up a modified Marauder TC with billet cover from Dirty Dog before he closed up. Link to comment Share on other sites More sharing options...

I picked up a modified Marauder TC with billet cover from Dirty Dog before he closed up. Whats the diameter of that marauder converter? I wanted to get something that was small (10" or smaller) so it could be stalled high and still keep some efficiency. Link to comment Share on other sites More sharing options...
droptoppony Posted August 5, 2017 Report Share Posted August 5, 2017 I think the Marauder TC is 11". Link to comment Share on other sites More sharing options...
Moderators LWARRIOR1016 Posted August 14, 2017 Author Moderators Report Share Posted August 14, 2017 Torque converter fun! Im going to get the roadrunner installed tomorrow. Link to comment Share on other sites More sharing options...
Moderators LWARRIOR1016 Posted August 16, 2017 Author Moderators Report Share Posted August 16, 2017 So I took it for a drive yesterday. Immediately I can tell the difference, I mean as soon as I started the car there was a difference. When I did the auto swap, I had to increase IAC duty cycle on startup because of it spinning the torque converter. This one, when I start it, the revs go up too high. I have to lower the IAC back down. Then going in gear, it doesnt slam like it did before. Driving around yesterday I was able to get it to flash 3200 before the tires broke loose. Im on my street tires so its to be expected. Im really thinking that It will flash somewhere between 3400-3600 when I hit it on the sticky tires. Overall, the car is more responsive to throttle input and so far the converter is doing what its supposed to. This is definitely an alternative if you dont have $800+ to drop right off the bat. Im going to run this for a while and see how it does. 1 Link to comment Share on other sites More sharing options...

Havent tried it yet, and probably wont get to for a little while. I am dead smack in the middle of doing paint work on it and I havent even tried to work out full throttle shift points or pressures yet. After I do paint, Ill get back to working on the tune. I may not run it until spring. 1 Link to comment Share on other sites More sharing options...
