The posilock locks up pretty early, if your tranny shifts real hard 2-3 you might hurt the trans.

Yank can make a non-posilocking kevlar super-clutch that would be better in my opinion.

Right now I have a 2900 stall non-posilock non-kevlar Yank. It is awesome. I lock it at WOT
and it works great! If I were to do it again I'd go with the kevlar clutch, non-posilock.

:confused:So you think locking up the trans yourself with a non-lockup converter is less stressful than getting one with posi-lockup?
I'am asking because I don't know. :(
 
A posilock converter locks itself at WOT. It will lock up in second gear and a hard 2-3 shift can hurt the trans.

The best way is to use a regular lockup (heavy duty) converter and lock it in third gear (75 mph or so)

My yank is not a posilock, but is it a lockup converter. I lock it at 75 mph or so and it ROCKS.

Bob,

How long have you had the converter? I'm angling towards one of these, but it seems like I heard someone had a problem with them....
 
I just put my Super Yank L/U in 30min ago. Have not run it yet but let me share my experience with YANK so far.

This is a long story but I'll keep it brief.

I bought a Art Carr nl/u 2 years ago. The converter was a POS from day one. I sent the converter back to AC a total of 4 tims, never getting what I needed.

I was about to scrap the converter and start over when I spoke to Mike @ Yank. Mike told me to sent it to him for a look. He rebuilt the converter (which had a POS stator that had burn hole in the fins as well as several other issues) and shipped it back within 4 days for $200. The converter I got back pulled like mad but was just a bit tight and slow spooling. Mike said to send it back and he would adjust it. He made a stall change and shipped it back within 2 days of recipt. The converter was a tad on the loose side, but worked flawlessly. At this point I called Mike to thank him a give him an update. My car dynoed just over 500rwhp (503 to be exact with this converter), but he felt it migh be blowing through the converter so we discussed his posi loc.

How to explain what happen next is unexplainable for me. Mike told me to send the nl/u AC he rebuilt and he would build me a Super Yank lockup. This was fine w/ me because I was leaning to the lock up based on my bad experiences with the nonlock Art Carr. Mike told me he felt bad that he could not get the AC to perform the way I wanted and would swap me even. He built me his $800 converter, and all I had spent with him was time and the original $200 rebuild fee.

Don't know how to explain it but I have never experienced customer service like what Yank has given through the whole process. Even if you take away the "free" l/u, the turnaround time on the rebuild and restalls was unbelieveable to say the least. Keep in mind, I don't know nor have ever met Mike. We're not cousins or old college chums. I'm just some guy who called him up on the phone one day and ask for help.

Its rare these days to get what you pay for, let alone more. Big thanks to Mike at Yank. If this converter performs half as well as you have I'm sure it will be the best.
 
I spoke with Yank today and they are working on the problems. They actually bought a GN to test with, and had to do lots of spring cleaning type stuff to get it in shape (plus it's their first turbo car but Mike sounds really enthusiastic about owning one and from his work so far it sounds like this will be a daily driver for him - great to have another convert). The turbo (TE61) was shot so he bought a new TE44 and TE61 from Limit Eng, to baseline the 44 as the current "stock replacement" and then to see how the 61 spools. They will start with a stock D5 and then move up to one of their turbo thruster 3000's, and then switch to a 2004r with a PTS bat brake so they can really abuse the converters for testing. Mike told me that the major problem he found with my converter was not heat from the tcc clutch dragging while brake torquing up, but was fin damage right at the hub from the combination of fluid flow, heat, and pressure from the torque multiplication they are trying to get. Apparently we just sit on the converter building boost longer than they can stand. Mine started out too tight and stayed that way until over 3 days it went from 24-2500 stall to 3500+ stall, then stayed there until I sent it back for him to examine. He has a new setup designed and will test it when their GN is ready, maybe in 3 weeks. He did offer again to refund my money now if I wanted, but I told him that I would wait until he tests his new parts before deciding. Someone gave me some grief in a private email about not supporting the existing vendors, but I feel that it is just as important to try to bring new vendors in, so I'm willing to let my money "ride" and see what he can come up with.
 
Thanks for the update Carl. I guess it's a foregone conclusion that I'll have the same problems. with my Yank.

I'll call Mike this week...gotta say I'm impressed by his willingness/effort to improve.

Regards, Bob
 
I have their basic gn turbo thruster 3000. Tim Dirks (trdirks here) has the same thing but set for 2800 stall and the kevlar clutch upgrade. Tim's was great at first (his is why I bought mine), but then suddenly developed a vibration and got loose. Mike said that both of ours looked similar inside, with bent over fins at the hub. Bob Bailey also has one of theirs, but I'm not sure which model and I don't think he's done much abusing it yet. Mine always made a whirring noise at light to full throttle which Mike attributes to the fluid flowing past the fins, and says that he has that corrected now (Bob may have a revised unit and if so, can you comment on the noise? Tim's was always quiet). It's frustrating to wait, but I think that when Mike is done he will have a very nice piece for us.
 
I have no noise except I hear a quiet squealling sound when at WOT and the trans shifts gears, or when I romp on it. It only lasts a half second or so. I believe it is the clutch assembly trying to lock up. I don't know if it's revised from your/Tim's or not. I'm certain it has no "bent over fins" improvement.

I spoke with Mike today and am very satisfied with his plan for me in particular, and with his intent to improve the converter overall.

It's a 3000 stall lockup w/Kevlar clutch and it's driveability is excellent...you'd never know it wasn't stock.

Mike encouraged me to take it to the track...I will within the next couple of weeks and advise.

Just thought I would jump in here with my .02. I've been running a Yank converter in my Camaro for 2 years now and it has worked flawlessly. The Camaro runs mid 11's and I race about every couple of weeks at the track. I'm sure Mike will make converters for Turbo Regals that will really kick butt, he does alot of testing on other cars and it shows. Also, he's a great guy to deal with. I'll probably not buy another converter for any car unless it comes from Mike. I've seen many people that were sold on other converters, that after trying one of the Yanks, thought they were better. Anyway, enough ranting, I don't even have one for my T yet. But I'm encouraged that Mike's got a turbo car now, I can't wait to see the results.
Mike
:D
BTW NEARING, what converter do you use in your Formula? Nice Sixty foot. My best has been a 1.69

Hey guys, sorry I'm so late.

I'm actually on my third one. I started all this after researching the converters on the f-body end of the world.

Mike is going thru the same education that all the other TR torque converter guys went thru. The first ones out of PI were real problems many years ago.

The first converter was too loose, too little RPM drop on the shifts. Mike spun me up another right away and I swapped it in. That one was EXCELLENT, but had that whining noise that you guys have noticed. I also had the carbon-ceramic TCC. The WOT TCC would not lock completely. That converter was a JOY to drive, very peppy.

After more conversation with Mike, he spun my up my current converter. It rocks as well, I have nothing but great words for it's manners. Mike put in a mid-level clutch because I was afraid of the Kevlar being harsh on part-throttle driving. The WOT TCC is excellent, The part throttle TCC is excellent. I'm going with Kevlar next based on reports from other guys that the part throttle manners are excellent.


I'm going to change it one more time. Only because I plan on having the engine out for some work. (And Mike has been very accomodating) I'm going up a couple hundred RPM, and I'm switching to Kevlar. (Non-posilock tho)

I think that the Yanks will be **THE** converter for the Buicks in very short order. The driveability is second to none (and I am very picky) and the WOT TCC that doesn't rattle is great. Yank as a vendor has been excellent. Buying a car (we all know how finicky these cars are) and doing all that work to it shows great commitment to us as a customer base.


Hope this covers it.

Carl,

Im surprised you didnt go for the Pro extreme line. When I was spoke to Mike he told me got that route with forced induction. The converter has more holding power than the other lines. Did he recomend it to you?
 
Are there any Pro Extremes that aren't like 3400 stall or higher??

I don't need that much converter, so I figured the TT line was better.

I could use a 3200... I guess.
 
No, Mike only recommended the gn turbo thruster, and didn't even recommend the kevlar clutch at my power level. I told him I run 110 mph and low 12's and wanted into the 11's. I think I will upgrade to kevlar, though, in my next one.
 
I've got a little yank 3000 with a 2.0 str in my Formula.
When I got it you only had 2 choices the 3000 or the super yank 3500.....NOW look at all the choices yank has!
