Im sure this has been asked millions of times but its my turn now I guess. Need a converter that does both well but leans a little more to the ProStreet or track side. Does need to be able to drive well though. Dont want a race converter, been there done that. Have always used Turbo Action but open to others. Car is around 3250lbs and is an ex-racecar being put on the street. Will take to the track and spray it every now and then. What size do you guys run for this application? 9 or 10 inch? What is a good stall to shoot for? Will any of the "off the shelf" converters work? I see Jegs has Turbo Actions in the new book.

Well Dynamic and Ultimate both make great dual use converters. So does PTC I hear. They seem to have a handle on making them tight for regular driving but at WOT will go to the stall you want for performance!


A little more money but worth it.

www.edgeracingconverters.com, Talk to Andre. I have one of their 9.5" converters in my street/strip Dart. It's been 1.38 60' in good air and works great on the street too.

I have the Luppo Dynamic 9.5 converter in my 63 and my boys Dart. They work great for us as ours are mostly street cars that might see the track a few times a year. Ron

Another vote for Dynamic. I am very happy with the 9-1/2" converter Shaun spec'd for my car. I'm sure that Ultimate, PTC or a few other companies could also offer great options. The key is to call the company, and have them build one specific to your combo.

When you compare prices, PTC is hard to beat. They have built several for me and they work.

I have one now that will flash 4,000 or 4,100 at the track, but will cruise at 2,800-3,000 with out too much heat.

They are Mopar guys at PTC that know their stuff.

Not enough info to give a recommendation,but I'd call PTC and give them all the info. I use PTC and have for years,but there are other good companies that can build a good converter as well.

Yes there are some good converter companies out there. I love the street/strip Dynamic I use as it will flash about 4200 and I cruise the highway all the time in the 3000 to 3300 area. I run the highway for about 90 miles like that driving to Carlisle and have never had problems as it cruises great like that. I also agree to call who ever you decide on and have them build it for your combo. You will have to give them all the combo specs. I used Turbo Action before also which also worked great for me. I just decided to go with Dynamic on my 63 since they are very close to me and were cheaper then the Turbo Action. I was glad I used the Dynamic as I could pick it up instead of having it shipped to me and it worked as good as the T/A. As was stated there is a few other real good converter companies out there but I really do like the Dynamic and Turbo Action converters. Ron

I have a 9.5 Dynamic too, works great!

Ultimate can custom build what you want, but they are more expensive than some others. I was leaning towards a 9-1/2" Dynamic because I had an older 10" Dynamic that worked well in my old setup. I talked to Ultimate, and they built me a custom 9" converter that on the street is tighter than my old 10" converter, but will flash stall to 5,000 RPM.

I just installed a PTC Converter in my car this fall. The engine builder specified a certain stall speed (4600) as he has built several of the same engine/ transmission combos over the years and knows what works. Gave PTC a call and provided engine, transmission, suspension, tire size, gear etc info to them and was told they would recommend a 3600 converter. I said I wanted a custom 4600 per the builder’s request. Was told it would not be a problem 4600 it is. Got the car running and guess what? Converter will only flash to 3600. Car will only 60’ in the high 1.7 range but runs low 11s. Called PTC to explain what was going on and was told I needed more stall speed (at least 4200). When I told them what stall speed was originally requested (4600) the phone went silent. I now have to pull the transmission out of a car I just got running, pay shipping to and from PTC just to get the stall speed I originally requested.

Sad part is-I removed a (3600) Turbo Action Converter from behind my old 340 that had been in the car for over ten years. Never had an issue driving on the street and performed great at the track. The Turbo Action Converter would click off mid 1.5 60’ and run high 11s all day long.

Everybody makes mistakes. Kenny is a standup guy. All you can ask is that he make it good. My PTC does exactly what I speced.

GTSDon,

Did I read your post right....the car with the TA converter went high 11s, and with the PTC converter went low 11s? Were there any other changes to the car?

PTC here. 9.5" 5000 stall.

davenc, that is not what I was trying to say. My old 340 engine and Turbo Action converter combo went 1.5- 60 foots and ran high 11s. New engine is a Shady Dell prepped 418 that should run high 10s in my car. Best 60 foot with new engine and PTC Converter is high 1.7s and 11:40 et.

Yes, I talked to PTC and they said send it back and they will make it right. My point was- it sucks that I have to pull the headers exhaust, transmission and whatever else out of the car and send the converter back just to get what I originally asked for. Not to mention the cost of fluids and shipping. Hopefully, they can get it right the second time. Not trying to bash or make anyone look bad, just posting about the issue I am currently going through.

My PTC conv was not any good when I tried to spray NOS as it kept breaking. I would send it back to Kenny, rebuild trans, reinstall rebuilt conv and 2nd NOS pass broke it again. This was his 8" conv and he knew all the spec's and was built for my purpose.
Broke it 2 different times, each time when I would hit the NOS.
Sent it back, he built me a 9.5", I had told him I SOLD the NOS and it was an all motor deal now, installed it and what a pig the car was, lost .50 in ET, called him and he messed up and built it for NOS, he was sorry and gave me an 8" per John Copes suggestion, I needed the stahl to be 5600 and when it was installed it was 6100.
I called and Kenny was Nice about it, wanted to help get it right BUT I was tired of all the issues and taking the trans in and out 4 times in 1 year. I left it in and sold the car a year later.
I Like PTC/Kenny but won't go thru that again.
Just my 2cents.

Continental here in Calif.............1-310--674-1072.......ask for Kris. Mines a 5000+ 8" that doesn`t heat up and drives awesome on the street even for fairly long hour plus runs and works pretty nicely at the track and it`s been in my car over 10 years I think...........

Heres a picture of the Dart I pm'd you about, good luck with yours, NICE car

Turbo Action here.We've never had any problems and they make the best product hands down.

small world, haha.
That lots next to a Georgia Pacific plant in Albany Ga. The car wasnt there long.
It was also fenced in so no one could get close, I sure wanted to check it out!!
I dont want to steer the thread away from your original question
have a good one

I have two T/A race converters, one is a older(built in the mid 1990s)8 inch SS/AH and the other is a nine inch T/A race hemi for the same car, I have used both in myy Duster and both worked great, much better than my ten inch Contitental street converter. The 8 inch was worth .2 and 2 MPH in the 1/8 mile with no other changes Suprised the heck out of me I drive it on the street and it is great It is really great for a race converter used on the street Some day I may have another custom built converter done for my Duster, but not real soon T/A race converters rock
