Will 273 gears be to loose with this SS 3600 converter? I use my car as a daily driver and go to the track once maybe twice a month.

I was looking at the vig 2800, vig 3200,
and yank ST 3200 now these new yank SS series look pretty good? I have a set of 323 gears that I could put in the car if it's still to loose with any of these converters? Give me all your thoughts guys.

 

Any high stall converter will feel looser behind 2.73 gears, than 3.23s or 3.73s, but I can't think of a tighter feeling high stall converter than the new Yank Super Stock 3600 and 3800.

I would highly recommend the SS3600 for 2.73 geared cars. The throttle tip-in response is outstanding...the best of any Yank converter. If you like the PI converters, the Vig 3200 (stalls 3800) would be my top choice. It rocks too.

 

Thanks Patrick G for your reply
How would that SS 3600 with 273 gears be from a roll? Would I see a difference from a stop and roll as well as top end with this converter compared to the stock setup? I am trying to say it's the best all around converter? What should I see for a ET with this converter. Sorry for all the questions. Should I put the 323 gears in after the converter or leave the 273 gears in?
Thanks

 

A SS 3600 will absolutely blow the stock converter away from a roll. Even though it has a very high stall torque ratio, it still has good shift extension. Here's what I mean: Shift 1-2 @ 6,000 rpms with your stock converter and your rpms will drop down to 3800-4000. With the SS 3600, the shifts only fall to 4800. Your motor is making a lot more power 800-1000 rpms higher in the powerband, therefore you will be faster from a roll. Now let's say you're at the bottom of 2nd gear and you mash the throttle. With the stock converter, your rpms could be close to 3000 rpms. It's a slooooowwww climb until your motor hits peak torque with the stock converter.

With the SS 3600, mash the throttle at the bottom of 2nd gear and your motor will jump to 4500 rpms (right at peak torque). No dead spots with this converter, ANYWHERE!!

I would keep the gears you have. I'm a big fan of 2.73 gears. As a matter of fact, I will probably be swapping to them if I don't sell my car. My future plans are to build a true street racing sleeper. 3.73 gears don't work well on pavement unless you're running ET Streets or Slicks. With a 2.73 gear, I can ride 1st gear for a long time without blowing my tires off at the starting line.

With a SS 3600 converter, you should see 5-7 tenths reduction of ET providing you can dead hook off the starting line. By that, I mean giving it full throttle on the starting line and there be absolutely no wheelspin. Do that and you will see your 7 tenths.

 

2.73s aren't as bad as you think with a good converter factored into the equation <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

I belive the 1-2 shift will bring the RPM down to around 3,200, so you'd be looking at more than an 800-1,000 RPM increase, meaning even more power than Patrick suggests. The 1-2 upshift is a MAJOR improvement with a TC.

Patrick, what TC would feel tighter in around town driving; the SS3600 with the 2.5 STR or the SS3800 with the 2.5STR? I'm curious why Yank would make the TCs seeming so very close to each other.

The stock converter has some slip (but no torque multiplication at that rpm) so that adds a couple hundred rpm. Also, during the gear shift and the moment after the shift when the rpms are starting to fall, the car is continuing to accelerate so that mph is increased by the time converter is fully coupled up and transmission gears are fully enaged.

 

Gearhead,

The SS3600 will feel a little tighter than the SS3800 soley for its lower stall. The higher STR on the SS3800 is a result of its higher stall. Both Super Stock Converters share the same 21 blade stator, the only difference is in the pump.

Yank makes the two converters only a few hundred rpm apart because in reality, most racers only need a few hundred rpm change to find the perfect converter with the least number of compromises. If a 3800 is not high enough, Yank makes Super Stock converters in the 4000+ rpm range too.

Thanks for explaining all that to me it makes perfect sence. I think I need to do a merry christmas to me early and go order this converter <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" />

For safe measures I should install a tranny cooler as well? If so which one would be ok for the Yank SS 3600?

Thanks once again to everyone who has given me there input.

Nice times Plum Crazy Rob <img border="0" alt="[Z06 Corvette]" title="" src="graemlins/z06.gif" />

Tranny coolers are always a good idea. I like the B&M Super Coolers personally. I've got the 19,000 gvw size. Tranny temps are always nice and low. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

 

Is that pretty big in size? Where did you mount it so it's out of the way and looks clean?

 

The cooler is 11 x 7.5" and it's mounted in front of the ac condensor.

 

Thanks for all your help <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
