Testing out the TH400 for the first time
FWIW, I've raced several liter bikes that MPH more than me (low 140's vs my mid 130s) but ET slower. From a roll it's a race and I've often inched ahead or stayed even every time they shifted.
My 10.0 @ 135 has the same acceleration as another vehicle that runs 10.5 @ 142. People often get caught up in the MPH game with the 6spd cars but having to disconnect the power source from the drive line multiple times during a race really affects your average power applied. It's not uncommon for turbo'd cars to gain mph and drop their et's after converting to an auto.
Of course a auto setup lives or dies on having the proper converter. Getting it correct makes all the difference. My converter is really nice, never have to go above 2500 rpms around town, stalls to 3500 on the trans brake before making boost and has 3% slip over 6600 rpms.

you have some sick *** friends, I got pulled over last year being clocked at 142 so i pretty much shut it down at 100 or so now. All I can say is thank god my mom is state popo! LOL
New setup has enough gear for 200mph. but theres no way in hell an 89 mustang will ever do that.
yes and no, that little slip just means I'm not making enough power yet
I don't know what PTC does, but for $900 they gave me a converter that drives around just a little tighter than my old Vigilante 9.5" that stalled to 3000 and had more slip up top. I've read that several turbo guys on theturboforums.com have gone faster with more slip like 8-12%.
This one flashes to 5200rpms with 15psi. The vigilante flashed to around 5600 with the same boost.
Dusty Bradford is who I bought mine through. Heard he was the wiz at stalling turbo cars.

P.S. I want to see more vids of your car Tiago, I love seeing vids of turbo TH400 cars
Plus, I've never driven a fast stalled AND turbo'd car. Hell, I've never driven a fast stalled car either for that matter
I wonder how my set up will differ from yours... 370/th400/ soon to be 2.75's in the back on a front mount TC78. Although mine is a PTC 3200

2. initially you'll keeping wanting to short shift because you are in the same gear FOREVER! Racing 50-140.. (on 28" tall tires with a 7k redline) no problem start in 2nd (brake boosting) end in 2nd (but shift to 3rd before letting off).
3. you can hold more boost on the foot brake before pushing through.
4. everyone will make fun of you for having granny gears, get used to it.
5. it's usually way faster than it feels because you don't get to feel the power curve like a manual car does.
The benefits are not buzzing the motor to drive 75mph so if you drive highway often you'll find yourself driving the car more frequently. I also find it easier to control wheel spin on the street and track. If it's going to be a drag car I'd suggest numerically higher gears, maybe 3.25's or 3.50's. 2.75's work good for a cruiser though.

i have had a stock th400 sitting in the shop for months and have been planning on putting it in my rear mount lt1 car,my question is how much do you guys do to the tranny to make it hold up,my car makes 640/640..i know that the converter is everything but what about your tranny internals?

Get the converter straightened out and that thing will be a missile. Even more so than before! Staging Lane
