I hooked a 1.7 with mine on BF Goodrich Comp TA Drag Radials, I had minor traction problems but overall, pretty good traction.

I still have a stock converter in my car, so again, take my opinions with a grain of salt <img src="images/icons/grin.gif" border="0"> . I agree - I said in my post that the ST3500 will ET lower than the SY3500 - maybe if you ran 0-140mph the SY3500's efficiency might help, but in the 1/4 mile there's not enough time to make up for the slower 60ft

At a decent track, the ST 3500 can be hooked with nittos. I did it and I know of others cutting 1.6x on them. ET Streets makes life easier at poor tracks.

My track (Ennis, Tx) has problems with my basically stock SS (lid & a few free mods). If I floor it off idle, I spin and have a poor 60ft - I have to roll into it even with a stock converter - granted I am running on stock tires. If I brake torque it up to 1200rpm or so & nail it - its even worse, and I am no longer pointed straight down the track <img src="images/icons/mad.gif" border="0">

My biggest problem with the ST3500 is the codes thrown & lockup problems that have been reported. My expectation of drivability problems with a high stall converter are - it's loose, and I might have to adjust my shift points because it runs through the gears faster, but throwing codes and having to keep it in D instead of OD to lockup seem like BS to me - I don't want to deal with these issues.

I have been thinking about these 2 converters for a long time also. My car is a daily driver that sees the track about 5 times a year. It also will never have DR's on it. Would the ST3500 just be to much for radial tires. Some people say yes some say no. This is the only problem deciding between the 2.

Without drag radials, you loose the benefit of the ST 3500's high STR for racing because you will have to ease into the throttle at launch. You can still get a good launch with practice and the high STR will improve the feeling of tightness. The SY 3500 will be easier to learn to launch hard because you can step further into the throttle before the tires will break loose.

I'm not sure what the "lockup" problems people are having with the ST3500. In the little town I live close to, you're lucky to get over 40mph anyway, so it just makes sense to keep it in 3rd for those very few times I get close to the 3-4 shift.
In any situation where I'll be cruising between 47-50 for a while, I can run in OD with no problems. To me it was very easy to adapt to. For some it might seem like a PITA, I don't know.
I'll point out that I have 2:73 gears, also.
My biggest problem was getting the shift points set,which admittedly was a bit of a PITA.

ST3500 all the way.

You can't hook it up on the street is <img src="graemlins/gr_bs.gif" border="0" alt="[bullshit]" /> ! I have no prob keeping it right on the edge of traction, just takes practice like anything else.

I pulled a 1.86 60ft on F1's with it and no spin whatsoever.

I don't understand it either. The only people that have answered they have had BOTH ST and SY said they like the ST better as an ALL AROUND converter and your still hooked on the SY. Even the guy that had the VERY FIRST SY3500 and has had 11 different converters said to go with an ST3500. Go figure.

As far as the probs with the ST, I have them and if you have ATAP wouldn't worry in the least.

I've thrown a code 2 times (Shift Solenoid Stuck-ON) and my converter wouldn't lock about 5 times since install. Code fix = cleared using ATAP. No lock-up fix = Pull over, turn car off, immediately start car and go. Thats it, no big deal.

The minor probs I've had are nothing compared to the fun I've had with my ST3500.

Only 4 times at the track eh? Don't you want to pull the front wheels off the ground those 4 times you goto the track? <img src="gr_images/icons/wink.gif" border="0">

Well it looks like I might be going to the ST after all. But I will probably go with a reduced stall like Ponchofan(sp?) did.

For those that can not understand why I was still sticking with the SY, well this is what I was basing my decision on:

The Super Yank 3500 is a breakthrough in street/strip converters. By using 21st Century materials and CNC manufacturing, the Super Yank provides a superior launch, without blowing the tires off the line. Our customers typically will pull 60' times on drag radials comparable to their competitor's cars on slicks. Although a SuperYank 3500 can easily roast the tires, you can launch nearly as hard on the street as you could at the strip. The SuperYank 3500 provides great midrange torque. The converter will increase torque out to 4500 rpm on an LS1. This eliminates the flat spots after upshifts and makes second gear a monster even at lower speeds. Because of its lower STR and strong midrange, the SuperYank 3500 teams with 3.73s to form a very hot street set-up. As an additional bonus, the Super Yank is the world leader in efficiency...that means your Super Yank will transform engine torque into rear wheel torque almost as efficiently as a manual transmission! All this in a converter that retains good drivability. (quoted directly from yanks website)

This sounded very appealing to me but I wanted to hear which was more streetable. I am not so much concerned with getting my 60's down to 1.6's or gaining 6 tenths at the track. I would sacrifice a tenth or two anyday so that my ride is streetable. I don't want to have to worry of codes or shifting into a different gear to get the TC to unlock it self. Or as NASSty01 mentioned above:
"I've thrown a code 2 times (Shift Solenoid Stuck-ON) and my converter wouldn't lock about 5 times since install. Code fix = cleared using ATAP. No lock-up fix = Pull over, turn car off, immediately start car and go. Thats it, no big deal".

This is exactly what I don't want. Some are all right with that but I am not.

But like I said I'm going to go with a ST3500 but with a slightly lowered stall.

Thanks for all your input

FWIW...My SY3500 has NEVER in over a year thrown ANY codes or had ANY lock-up problems at all. I've 60'ed great (1.69 to 1.78 depending on conditions) on a stock motor on DRs, it's great on the street and hooks A LOT easier than my friends Vig 3200 (which is probably more compariable to a ST3500).

My local track SUCKS (GLD) and almost everyone needs at least DRs to hook, even stock cars (except for those luck times they lay the VHT down thick). This made the SY an easy choice for me. I have a hard time getting even the SY to hook sometimes, and my vig3200 friend can almost never hook on any street type tire at this track.

Point is, the SY has been good to me. I have seen no reason to think about a switch in my application as of yet.

Are you looking to run record fast times with your car and maybe have some minor issues? ST3500 is a good chioce. Are you looking for an issue free 'verter that will work great on the street but run a coupe tenths slower at the track and feel a little looser? SY3500 fits the bill.

The SY will never be a record breaking 'verter, but it's been damn good to me. <img src="gr_stretch.gif" border="0">

That's a weird thing about the codes. I have not had any codes at all, but I know quite a few evidently do. And as I said, no lockup probs.
If I remember right, reducing the stall will also reduce the STR, so it all might work out for your ride to get the ST with reduced stall.
I waffled back and forth between the SY or ST, but even though I haven't driven w/ the SY, I'm happy with my choice. Even with 2:73s it will scorch street radials, but it's easy to feather off the line with just a little practice.
Heck man, it's your car. Get what you want!
Good luck on your decision.

I would not go down to 3000. Stay with a 3200/3300. I would use a 3000 primarily for 2.73 gear cars.

Thanks for the suggestion. When I finally do order it I'm going to talk to Mike @ Yank and see what he thinks about reducing it to 32-3300. But from the sounds of it that is probably just what I'm looking for.

Just for the record's sake... I removed the MTI ported Throttle body after having "Idle Speed High" code thrown repeatedly only after the converter installed. With a stock throttle body in there it has yet to throw the code and it's been over a week now. Other than that I've had no (count'em: zero) problems with the ST3500.

I have the SY3500 with a little extra STR because of my heads/cam. Well here's my take on it. The SY is so loose as everyone says it's just plain sucks on the street. I have 3:23 gears and for the rest of the mods look in my sig. FWIW I raced a very fast Mustang a few weeks back. The car is a GT Convertible 306 Stroker with GT40 Ported and Polished Heads and a Z cam I think with a T-Trim Vortech running 17psi. He's a friend of mine and he was on ET Streets as I was on street tires. We went from a 10mph roll which I still went sideways into his lane. He pulled an easy 3 cars on me in 1st and then I hit 2nd gear and I started catching up. I have tranny issues with the Yank Sportsman Pro and by the end of 2nd I had caught him, but my car won't go into 3rd gear at WOT. FWIW I like the SY 3500, but I think my car would benefit from a better converter. I cut a 1.8 60' on street tires, but I didn't launch at nearly any throttle at all. I ran a 12.36@96mph in 2nd gear. I am in the process of putting in the next tranny Mike at Yank sent me, this will make 3 of his and 1 stock replacement from warranty. Anyway I do need tires to find the full potential of this stall, but I think I am going to go with something like the ST3500, but I've had so many issues with hitting the rev limiter on the 2-3 shift that I'm not sure I want that if this tranny makes it go away. Ed Wright has been excellent to work with though, he's kept my shift points very low so as not to hurt my motor. I hope this Yank Tranny works. If it works I am going to put 3:73 gears in and see how they are, then if I am not anymore happier than I am right now, I will go to something different.

I have 3.23s w/ my SY3500. It doesn’t feel loose at all to me <img src="images/icons/confused.gif" border="0"> I guess everyone’s perception is different...

dand35th

I have the sy3500 with 3.23's as well and I don't think its loose either!!

Snake Skinner

Are you two guys head/cam cars? If not, then that might be the difference as I have heard each converter will feel much differently with a bolton car versus a head/cam type car. As you know each converter is different so that could be the difference too. Also it could be that my tranny's slipped ever since I got the thing and that may be the whole deal there. I'll let you know when I get the tranny back in the car.

dand35th

mines totally stock. Hope only until this weekend when I may put the H/C in

Superman

ST this SY that....

Just get a Vig. 3200 and forgadabout it.

If you thinks it`ll be too loose... even tho it`s tottally streetable.. have it stalled down to a 3000 stall... it`s a perfect street/strip converter that won`t throw any codes....
