So my trans just went out on me and when I pull the trans. I am thinking about bumping my stall up from a 3600k to a 4k or 4200k. I'm pushing 440 rwhp and its a weekend toy and I hit the track around 4 times a year. So I am wondering what stall size yall think I should run? I call Chris at circle d and he said I should do 4200k. I also call Dave at yank and he said 4k.

My other question is the brand of my converter. Right now I have a vigilante and I would have Chris at circle d to bump it up to a 4k or 4200k. For two to three hundred dollars. Or should I sell is and buy a yank pt4000? The reason for the pt is the motor is n/a and will stay that way. So is it worth spending 900 on a new yank or just a few hundred on the vigilante?

 

I prefer ptc out of Alabama.. 4000-4400.

 

Well if you can have your current converter restalled by a reputable shop like circle d like you said then go for it.

Since its not a track car and will be a street car mainly you shouldn't go too big. Anything 4000 should be fine.

Lemons any reason you say 4-4400? Isn't a 4400 a little big for a car that'll see the track only a handful of time a year?

 

I wouldn't go any more than a 4000 on a primarily street car myself

 

Most people here have only tried a few brands of converter; I have only tried two TCIs and a Yank 3600. I am very impressed by how tight the Yank is in street driving. From reading every post here for the past year or so, I get the feeling that while a PTC or Circle-D is faster at the track, the Yank is tighter on the street.

I got the same track ET and even 60ft times with both a TCI 2400 and Yank 3600 because my '81 Camaro has so little traction even with DR. (I'm working on it.) So my NOVICE feeling is not to increase the stall speed if you are already having traction problems with a lower stall. In my NOVICE opinion, not having compared a 3600 and 4000 on the street, for such occasional track time I would suggest a Yank 3200 or 3600. (Many people here take their track times much more seriously than I do; I drive thousands of miles on the street.)

For what you are talking about getting it re-stalled you could probably get a new converter from PTC for... then sells yours and get some of your money back.

I daily drove my car for a while with a PTC 9.5" 3500 nitrous converter in it and never had any issues, the car actually acted like it needed more of a stall in it.

 

My reasoning for recommending that is in bold.

I wouldn't hesitate to DD a 4000, I did with a PTC for around a year.
I DD a Vig 4000 (more like a 4400) for over 2 years, I like large converters.

With the car being a weekend toy, why go with a Yank that takes 50 RPMs less to leave a red light (all else equal) when you could 60'/ET quicker and mph the same with the PTC?
If you are already contemplating going with a 4000+ converter, that little extra bit of "tightness" is a non-existent issue in my eyes.

If you can't hook a 4400, you can't hook a 4000.

For me... A car that was always staying NA wouldn't have anything less than a 4400 converter in it. My old setup was a baby 226 .588 114 cam and it hadc a 4000 in it, cut 1.50 short times barely spinning on motor with a nitrous tune full weight.. Get a car to 60' and you have a quick car, period. And that takes a hard hitting large converter.

 

Lemons12, how did you like the vigilante 4k? I am really leaning towards keeping the vig and just restall it. Really thinking about doing 4200k. I had circle d already restall it from a 3200 to a 3600. Chris said it would only be two hundred and make three hundred.

Thanks everyone for there opinions and keep them coming!

 

The big converters are known to stall higher too, a Vig 4000 may stall to 4200 or 4400. I know lemons alluded to that above, just wanted to state it explicitly just in case.

 

i daily drive a 4000 ptc .iam thinking of restalling to a 4400

 

I daily drove a Yank SS4000 with 3.23's for over a year. On good drag radials and a prepped track my car would leave at 4000 rpms.

 

My street car = ultimate converter concepts 5000 rpm.

 

Well I am pulling my trans today and I am thinking of making the stall 4k.

 

I need to pull my flexplate and I'm thinking about restalling my SS3600 to a 4000.

I also like PTC and only went with a Yank because of the smoking deal I got. Lemons has given pretty solid advice...

 

Well I plan on dropping off my converter Friday. I think I'm going to go with 4k but im going to ask Chris at circle d and see what he recommends again.

I'll let everyone what what I go with and how I like it on the street. Them when I get time to hit the track, I'll let everyone know how my 60ft are.

 

I went from a vigilante 3200 to a circle D 5C 4000-4200 stall.. AMAZING!!!

A 4000 stall is not huge to drive around for a daily. My drivability was the same. I would go with a circle D!

 

Sorry, I missed this until just now.

I liked it a lot really.. However, it lacked the efficiency I want out of a converter. It hit extremely hard out of the hole and had good extensions though.

Acted more like a 4400 than a 4000.

My 226 cam setup with the PTC 4000 (stock ls6 intake, 3500#, full exhaust, hand ported 317s, etc etc) trapped within 2mph of my Ms4 setup trapped (ported FAST 90, TDs before axle, PRC stg 1 ls6, 3200#, etc).. I chalk it up to the PTC being a better all around converter.
