Congrats man! Sounds like you are having a blast falling in love with your car all over again?

Congratulating you on your success with the trans. Looks like liberty is going to make some money lol

RE Motorsports 11-25-10 09:52 PM

Wow, i can't believe I missed this thread! LOL

Congrats of your choice! :nod:

These modifications through liberty are a great alternative for our boxes. The local rotary guy mentioned by Paul and Craig was me! :lol: Over the past 4 years, Paul and I have been working veryyy close in designing a box that is geared toward our engines.

At this point, the transmission in your car is the best design to date that I have tested in my own car. I have been running this box for almost 4 years. It takes a bit of getting used to in the beginning, but just remember, the harder you drive it, the better it works! LOL

I highly recommend this over any other street setup out there, it is cost effective and veryyy efficient. Unless someone is building a crazy race car, the 5-speed clutchless units are the only way to go. But for the average guy like you and me, this is, in my opinion the only way to go.

I have made great power and torque with my car and have yet to see a transmission failure. Non-stop abuse at the track, the street, anywhere and everywhere. No case flex, no output failure, NOTHING! Rest assured, you have a well designed and PROVEN transmission! :nod:

i called jason at liberty i believe that was his name and they told me 1500 for everything except the 300mm output shaft or with the 300mm output shaft it would be right at 2000 for the works

i think you mean 300M chromoly output shaft

sk8world 11-28-10 08:47 PM

Sorry guys, been out of town for kids hockey tournament.

I cant speak for what it will cost you to have this done as I did a new input shaft and cluster along with a few other parts. Call Liberty (Paul) or talk with Enzo on here.

Also dont want guys miss lead here. My times were much better but it wasnt all due to the tranny. I have never ran 27.5psi with the 2 step working. My log shows 1.45 bars (21.5psi) on the first read! Also was launching around 9200rpm, track was on kill mood, and air quality was PERFECT!

Watch my 2-3 shift! Was one of my slowest shifts ever logged.

Did the tranny help? YES
Would I do it again? YES

But it didnt alone shave .4 seconds on my 1/8th mile pass. It will make you faster and shifting a breeeze.

Just dont want guys paying all this $$ and coming back to me upset they didnt shave off 1/2 second. As Enzo said, if you already shift properly and get this and shift it flat (no lift on the gas) then you should shave another .1 per shift.

To put it into a better prespective without changes,, I went 9.85 with my stock tranny didnt change a thing put my liberty box in and went 9.78. same trap same 60' both runs.

I dont believe you can shave off .4 unless you eliminate stepping on the clutch or you were a grandma shifter to begin with.

That was the point I was trying to make. I had much more going on then a new tranny!

sk8world 12-11-10 12:45 AM

another video of the shifting. Never went above 5800rpm and running 1 bar or less. I am getting better at it!

sounds like you are getting the hang of it, vids like this are going to make me send out my spare tranny to liberty!!!

turboR1 12-14-10 07:43 PM

Since your posting videos of the tranny I might as well share too. sk8world tell me if you hear a familiar sound before I stage lol.

Yeah, right at the :15 you can here it. Funny thing is on my first pass at that same point after the burn out I grinded the shit out of 1st because I didnt slip it until it found 1st. My bro was like oh crap, here comes a shitty pass thinking I didnt have it together mentally.

BTW thats one nice pass. Love how the car launched and stayed down. Shifts sounded nice!

turboR1 12-17-10 04:11 PM

Thanks. Yea I always have to put it in 2nd before 1st otherwise it wont go in. I get nervous from the sounds it makes sometimes feels like its going to explode but its fine.

ArmyOfOne 12-17-10 05:50 PM

I love that track. We used to go up to island raceway and do like 10 passes in one morning. So if they can do 3rd gen trannies then TII trannis should be the same proccess right?

what RPM do you launch?

enzo250 12-21-10 08:24 AM

Depending on track conditions anywhere from 7500-8000

sk8world 12-21-10 03:40 PM

got to find what works for you. My 1.39 was on 9200rpm!

enzo250 12-21-10 04:10 PM

Nice.. Yeah it's all dependent on your motor and where power comes in at and how much of it your tires will hold.. :)

beefcake 12-21-10 05:20 PM

good point piston man, as my banana launches at 8750 but with only 2 ~ 3 psi boost on the hit , good for 1.32 ,
Im definitely going to be looking into buying a s4/5 box minus bellhousing in the new year from someone over there and getting the work done , saves me some freight from sending it to an from Australia
I still cant afford a real mans box :(
