3300 yank converter?
I no longer have the '99, but I kept the TC. Installed the TC on my new 2001 Firehawk last week. My 2001 has 1500 miles on it now, took it to the track last night. The TC only lowered my E.T. by .2. I was hoping for a lot better times.
Stock my 60' was 2.05
With TC 60' was 1.95
Could it have something to do with the install? Or was it the gears that made my other Hawk do so well.
I read on here about "STR" on the converters. I don't know what my "STR" is. Does anyone on here know anything about my converter?
Thank-you, Becky
Do you have any wheelspin? If you do, then there's your problem. If the car is dead-hooking and only giving you 1.95 60' times, then look for other problems. Could be install related, but it's doubtful. Could be torque management. I will tell you this...it's not the converter.

I am going to guess that the TC+Gears is what netted you great 60's, do you plan on doing the gears on this 'hawk?
Are you running street tires or DRs? With that TC and 3.23s you should be able to pull 1.8 60's at Greer easily with DRs. street tires is a different story.
I have some new 'stuff', so i hope to pull 1.6's or better now out of the ole LT motor!! <img src="gr_grin.gif" border="0">
The track was crazy Thursday Night just too many people and not enough manners if you know what I mean.
I was running on my Firehawk tires. The best time I got is when I did a burnout on them (ouch) and I had no wheel spin. 60’ time was 1.95, E.T. 8.65 at (if I remember) about 80 mph.
I believe Patrick G is right, something is wrong. Maybe she is just doesn’t have enough miles on her yet. Hope that is all. I am calling her “GrannyHawk” Just doesn’t deserve the “Fire” yet. Lol.
I was hoping not to have to change the gears, but I will probable put in 3.73s again.
Going today and see if I can do any better, latter.
If anyone else has any suggestions on where to start looking for that “something wrong” let me know, Thank-you, Becky
cutting 1.95s is pretty good on street tires.
how many miles is on the hawk now?
does it flash to 3300?
possibly the TC is just not set up right...if that is the case, just go ahead and get the ST3500 or the 4400 stall that will really make the car move, even with the 3.23s!!
<strong>Becky, update, did you go Saturday or did it rain down there?

I got to make 5 runs before it started to rain and they called off the race.
Had about the same times yesterday as before. 60' 1.95, ET 8.67, 81 mph.
I believe part my trouble has something to do with Traction control. I don't think it really shuts off right all the time. Also I think this converter really needs the 3.73 gears. It is really "loose".
I think I will get the 3.73s and a new traction control switch and go from there. See what happens. Still only have about 1600 mile on her.

<strong>Trust me, you don't need 3.73 gears to get 1.70 60' times with this converter. You need to address the issues that have you down on power first. With that converter, 3.73 gears will help you, a best, a tenth of a second.</strong><hr></blockquote>
I'll have the dealer look at it this week. Hope they can find out what is wrong.
The STR is 2.2 according to Yank's web site http://www.converter.cc/ . Hope this helps.

You can test that out theory without buying anything. Next time you go to the track, just pop the hood and unplug it. The connector is on the black lines on the passenger front side of the engine compartment. Takes 15 seconds; No tools needed. I do that so that I don't stage or start a burnout with it on.
I agree with Patrick. That converter will cut 1.7x with 3.23s no problem.
