Anyone running this combo? I also have 3.23 gears. What E/t's and dyno numbers do you see?
I also have a nx 100 shot.

 

on motor it wont make ****, thats just the nature of the th400. mine lost TONS of power. however there have been a few cars down here in texas with th400 GOOD CONVERTER and nitrous running low 6s 1/8th mile with a ms3. the ms3 likes compression and nitrous. achieve those two things and you'll be fine.

 

well with the setup that i did have i had a 3200 stall, 216/220 cam and 100 shot.. and misc stuff like lid, pulley ...

i want to see atleast a high 11.
i seen a 12.1 on my old setup w/o LTs

 

do you already have a th400? i don't see why you would want a th400 if your goal is only a high 11. i went high 11s with a stock internal car on motor with a 4l60e

 

I went through to many 4l60e's . Last one i bought was a rock-on and i got bent over on that deal.. I was taking in consideration that the powerloss with the th400 .. so the cam will make up power to get me into the high 11's.

 

if you're breaking 4L60Es at the power level you are currently at you are doing something wrong. My car went 11.20s at 3500# with a BONE STOCK 4L60E and Yank PT4200. I'd figure out what the problem is there first before you go wasting money on things you don't need. What converter are you running?

 

well i guess your a luckly one. i have more plans for my car im just getting it ready.. i went 11.1 @ 123 with a stock tranny also.. and a 3200 tci . I Dont know if you know about rock-on but , 10 or more people got F,ed over and i was one of them.. insted of paying 1500 for a rebuild ill pay 500.. Im just tired of pos 4l60e

 

How much power is lost with a th400?

 

my car felt like it lost about 50rwhp after the th400 swap, BUT that was going from a pt4200 (loooooseeeee) converter to a ptc 4000 nitrous converter (tiiiiiggggggggght)

 

yeah ill just buy some heads to make up for the loss .. heh

 

Ive heard people cutting off time from their et's going to a th400.
