Circle track 904. I will need a good one off the shelf or possibly a custom built exact for my app. I had heard that Frank Lupo back east (Dynamic transmissions iirc) was good but that was many years ago. Any recommendations? thank you for your time.

Dynamic still makes great TQ converters. 1-877-846-lupo

We use Neal Chance. Sure Marty there can get you what you want. Not sure how big into circle track they are though...

Is this for IMCA Hobbystock? We always used a stock converter or made a dummy converter. IMCA rules says minimum 10" holding 3 quarts of fluid with a .125" drain plug. My stockcar is currently using a stock converter. I have toyed with the idea of a high stall converter but never tried it. Not sure how much stall you can get in a 10" converter and it would probably just spin the tires more. I feel if your losing the race off the corner you need to work on the chassis. First one on the gas wins the race down the straight away.

Yes, our money is right (finally) so I'm thinking we want an edge that the chebbies wont have. (& that item cant be claimed). I'm looking forward to seeing you out there.

I bought a 9.5" 4K stall converter from Dynamic as well. They were good to talk too, although the phone calls we had always seemed rushed for some reason...LOL. Anyways, the converter does what I was promised on the phone it would do, so no complaints.

As to how good of a converter it is? Well, I really do not know my drivetrain stuff well enough to answer that...so no idea regarding the efficiency (% slippage), etc, etc...

Call Kenny at PTC

ptc

I have a PTC in my car .
With that said I would go with ultimate .
PTC only gives a month if it needs to be restalled .
Most other places I have called and dealt with in the past have been a year .
And when you spend 1300 on a conv. and have to spend 300 more plus shipping to have it restalled it kind of sucks.

No more PTC for me.

I have bought several converters from PTC over the years and they have always worked good.

But this last converter has been a royal pain. First, the flash was way high and the snout did not fit in the crank until I worked it over.

Called them, sent it back, got it back, but it is still too high. When I called Kenny again, he said it will be hard to get the flash any lower on that size converter. The size they chose with dyno sheets, etc. He acted rushed and said to send it back and he would try to lower it some more.

And did I mention the engine shakes around 2,000 now? I suspect it is the converter.

Anyway, I called Lenny @ Ultimate. Although I have never spent a dime with him, he took more time and asked more questions than Kenny ever has.

I am pulling the engine and tranny now and will send the converter to Ultimate to see if anything can be done with it or if I have to start all over again.

Maybe PTC doesn't have time for us small fish anymore.

Yeah told me it would be 2 to 3 weeks for a custom converter .
Showed up in 3 days .
I called him and got some story about them being slow and they got it knocked right out .
Me I'm pretty sure it was just one they stock and said close enough .

Lenny @ Ultimate FTW

Robert..Lenny tore down my conv so he could
change the stall and clean it out after
getting trash in it.. its fine now and he
did a nice job stalls lower and works great
in my street rod.. stalls at 4500.. give him
a call and see what he can do for ya..yours
will be different being a circle tracker but
its worth a call
EDIT
I have run a few conv
2--Turbo Action
1-- Coan
1-- Transmission Specialties
and the Ultimate thats in it now
Ultimate and TA have been the best

Luppo Dynamic here. Ron

No fan of dynamic

Don't think chance builds mopar

PTC has been hit, or miss, though they will work it all out with you (honest co)

Coan has made the best mope converters I've ever owned, and have all been really close from the start. Stay far, far away from their in house built mope transmissions though. Calling them junk is being kind...

I had a bad experience w/ PTC also.

I'd use Ultimate if I was to stray away from my local guy.

I've always used ATI with great luck.

You'll have to, because he'll never call you. That was my experience.

Call John Cope at CRT.The guy is an expert on Mopars.Just tell him what you have and want and he will do it.Rocky

Have had good luck with Lenny at ultimate
TCS nailed my procharged hemi's converter

Hmm, surprised to see all of the bad feed back about PTC. I have used & ran them all. Only bad luck I ever had was a 8" TCI got trashed one time on the street. I am on my 4th PTC now.(4 different cars). One has been in my Charger for 10 years or so 10" 3800. Current new convertor is in my Challenger to be tested this summer. It almost always seems like they all have to tighten them or loosen them 500 +/- RPM or so at least once these days???

TCS does great work.

Had great luck with PTC.

Had a nightmare with Dynamic in Connecticut...they cost me a full season of racing and $600 .

Yes there is two Dynamic s as Luppo's Dynamic that I use is in Newark Del I believe. I like them alot. Also Turbo Action has always been a top notch converter. Ron

Is that the Connecticut Dynamic or Lupo Dynamic? To clarify, who is "chance"?

Sorry, my 2 worst converter experiences were with Lupo dynamic.

One of the best units I ever put in a Mopar was a Lupo
Some of the worst I have ever had were Lupo

PTC hit or miss

Turbo Action finest quality work always seem too tight and way too $$ on simple fresh up etc ( but...I would sleep with an original J under my pillow if I could find a new one) When we all had stock 440 stuff with a 590 or 650 solid these were the Dream Mopar units and always will be IMO for a footbrake car

I have been very happy with Cameron at Torque Converter Services in Columbia SC Cheap to get one opened and worked--FAST as can be turn around--as much skill and know how as any shop--well equipped shop and he really listens did I say VERY reasonable $$$

Neal Chance, he makes some real good take apart high end converters as well as regular race converters for high HP applications.

The conv that Ultimate just did for me is a TA J thats
in my car now.. he said it was a nice conv.. I have one
more thats for the race car
