Getrag or Torque Converter

I am up in the air on what my next mod should be. As the title states, I am debating between a rear or torque converter. I have spoken with some people and it was suggested to pick up a TC and upgrade the axles to 09+ RT axles. I could still get some drag radials and be "safe" enough without breaking anything. On the other end of that I would eventually like to upgrade the rear to a Getrag, so it seems like i would be wasting a little money purchasing 09+ axles. Ultimately I am shooting for a mid to low 12 second daily driver. For those of you that have/had both, what did you do or what would you suggest? Currently don't have the funds for both.

My current mods are cam, t-stat, "cai", hi flow mids, johan tune, UD pulley.

Currently I am running consistent 13.3's @ 105-107mph on street tires (RSA's). 60' is consisten at 2.1. Best time so far is 13.1@105.

I would do the rear first. But, a torque converter will probably net you better gains at the track. I didn't like the TC until I installed a MTCM to lock it sooner, so that's another expense you may end up with there. Also, I don't know how a TC plays into things, but you might want to look into a valve body or maybe blue tops before you get the 2-3 slip. I say rear first because, it's going to change what axles you need and also, if you go with a different ratio it'll be a little more fun around town. It's really hard to flash the converter under normal driving, kind of a track only thing. I don't know how the TC will perform with an open rear end. I have a 3.73, but now that the 3.23 is available I'd go with that and try to hold 3rd through the traps. Also, if you are going to drive in the snow, the getrag will make a difference there as well.

Thanks Bill, I am actually thinking about a 3.55 Getrag. Still trying to read up on them but from what I have read, the 3.23 and 3.55 are similar in price.

3.55 is probably a good gear. I don't know if prices have changed or not, but for a while the 3.73 were stupid expensive. I shift 100 ft or so before the stripe and it's pretty obnoxious. I don't know if 3.55 will hold 3rd, probably with a 28" tire, but maybe not the 26". You could go 3.92 and wind out 4th. I've seen a few people that were able to snag a getrag really cheap from a pick apart. Might be worth a little investigation.

i love my 3.55's. i think it is the max i would want on the highway.

i don't have a getrag though. i went wavetrac rear end, 3.55's, and 09 R/T axles/hubs.

I put a 3.55 in mine this year with the upgraded half shafts and it really woke the car up.I couldnt be happier

I drove out to ohio and had Erik at BFNY install it. Took him a little over 2hrs and the job was done. He does great work

That's basically what I what I wanted to know.

I contacted Tim for an estimate first at MPH. After about a month of not hearing from him he contacted me,told me I got overlooked, and asked if I still wanted an estimate. I told him yes and that was the last I ever heard from him. Honestly I have no regrets going out to BFNY for the install. Me and the wife just made a 2 day trip out of it and had a blast. I plan on heading out there again next year for some more work
