TT2800 3.0str 60ft?
For guys that used the TT2800 or TT3000 3.0 str TCs, what kind of 60 ft times did you cut? Did your trap speed also improve? It is hard to believe that a 3.0 str TC has higher efficiency than stock TC. But that is what Yanks website info indicates. All replies welcome! Thanks

I had the prototype TT2800 3.0 in my car when I was bolt-ons with 3.23s. My 60' sucked. The converter is very tight and hard hitting and I had eagle RSAs at that time. I spun those tires anytime I hit the converter hard from a dead stop. With nittos, you could see 1.7s with your 3.42 gears, but that converter is really designed to dig a 2.73 car out of the hole. Yes, my passing times felt much better and I gained 1 mph or so over stock.
Get an SS3600 to SS4000 or get a SY 3500. They will do much better with your 3.42s.

Thank you for your replies! Before I posted this, I did a search and came up with just one guy having terrible 60 ft times, 1.8s, with the TT3000. That turned me off. But after looking at the Yank website's dyno curves & description for the 3.0 str TCs, the TT2800 has all of the characteristics that I do not want to give up if I ever go to upgrade the stock TC. Tight, good throttle response, more torque multiplication, & more efficient on the top end.
I've driven old school hi-stalls before on past cars I've owned. I've driven a Yank 3000 on another F-body and did NOT like the looseness. I watched Sam's video with the TCI SSF3500 and feel that would be way too loose (Thanks Sam for posting that video).
I read how the Yank SS series compare to other TCs and don't have a good mental feel for them yet. It seems like they are over-rated for NA setups. Meaning that a 4000, 3800, 3600 stall by name has the shift extension and tightness of a 3500, 3200, 2800, respectively. Maybe on spray, they act like their namesake?? I dunno, I am probably totally wrong, its just my perspective at this point in time. But if they feel like the Yank 3000, no thank you.
I want primarily a STREET converter. I may try my hand at SCCA racing soon and I desire a good throttle feel. It seems the TT2800 will be a good multi-purpose converter. That's why I'm interested in it. Good street manners, a benefit on the drag strip, and tight enough for driving around a coned track. If it is not, please let me know. If it is going to suck on the drag strip, I am not going to run it. I run Hoosier QTPs at the drag strip and some suspension mods to help hook. Right now, I got ample traction and feel lowend limited by both the stock TC and the near stock horsepower.

It will hook with your QTP's, but it is a small converter (relative to the stall used by serious drag racers). You can't expect to use just 1600 rpms in town and be able to cut 1.6 60' times. It takes some looseness to slip the engine into the higher rpms and to generate the torque multiplication over a long enough rpm range to get a killer 60'.
Throttle feel is not the same as performance. It can feel mushy and still perform better than stock. Besides if you are going to do SCCA, you should get Edit to adjust your part throttle shift points for race day. you can then adjust them a bit higher for street use which really tighten things up with a high stall.
I haven't driven the SS3600, but I know one guy who doesn't like loose converters said that it feels real tight.

My best 60 ft times with the stock TC are 1.90x. If I can get low 1.7s, & somewheres near a 0.35 to 0.4 sec ET improvement, then I'll be satisfied. Ragtop, do you feel the TT2800 can do it?
I have access to LS1Edit through a shared cable. I have not yet messed with it. I was getting hyped about the new Vinci/Crane Powermax tuner which I thought would allow me to adjust part throttle shift points & TC lockup. But after reading more about it, it doesn't appear to be as adjustable as I thought. So, switching transmission settings is not very convenient for me at this time. I appreciate & value your input since you have first hand experience with that TC. Thanks!
Anybody else that ran that TC have an opinion to share?

Ahhhhh!!! I read through some more old posts on various sites and found a couple more guys with lousy 60 ft times with the 3.0 str TCs.
Hey Ragtop99, what do you think about a Vig 2800? Would it be at least close in drivability to a TT2800?

my converter at partial throttle feels as if i were towing a motor cycle on a trailer behind me, it does not feel like its slipping. when you give it a little more throttle, it wakes up like i just lost the trailer and added about 20-30 more hp. as far as getting a 3.0 str i can tell you that i had problems at the track on 10.5 et streets, 60 fts varied from 1.70- to mid 1.85 before i had a cam.now im on et drags on 8.5 inch rims and my 60 fts are always in the mid 1.60s . a 3.0 str will toast nittos!!! my 60 were in the mid 1.80s they sucked,i could not wait to get slicks!! hpoe this helps!!

I hate my TT 2800 3.0... It is the older one when they first came out with it... Its too much like stock i dont even know its there. as far as improvements i dunno... the track wasnt open until after i put it in the car... as for 60s... i did 2.19s on blad street tires... 2.0x on NT555Rs... it flashes at about 2600ish foot stalled at 1800 i thought it was fed up myslef. but the guy i bought it from claimed it wasnt. but when it flashed it HIT HARD, at the track i just foot stalled it. so i dunno. id recommend sumthin bigger and better myself. I have heard nething but good from the Vig 2800 2.5...
For a compairison tho my buddy has a 01 vette... BONE STOCK... he pulled 2.1 60s spinning and trapped 2-3mph lower than i did. i usually beat most catback lid ls1s by 1/2 to 1 car length... hope this helps...

Thank you gentlemen for the added information!
Are the not-so-great 60 ft times due to traction problems or just that the converter is so tight that it doesn't rev-up quickly?

my times were cuz it did rev up quick unuff kinda bogged with the nittos on bald street tires it was bcuz it spun... u also have to note that NHRA has LTs and better gears...
Tho i will also tell you this.... the guy that previous owned the car had it full bolt on and NX runnin a 224 cam w/ 3.23s it jumped 1.5s 60s no prob with the TT2800 3.0... so i dunno.
