4l80e for a turbo car
I have a Hughes-built 80E and love it, and I'm currently in the 630rwhp range with a blown 383, and heading towards the high 6xxrwhp range when I finish this 434" motor. Then comes the nitrous/methanol setup which should easily put me in the high 800 rwt range.
The only thing I'm changing with the bump is the converter - I really want solid lockup performance under WOT - so I went to a 9.5", 5-disc Vigilante lockup rated to 1600HP.
Total in the 80E, converter and electronics to date: $5800. If I could have found an 80E core to send them, I could have gotten $1000 back, but nothing was around that made it worthwhile factoring in the shipping.
My rough measurements show the entire combo weighs about 80 lbs. more than the 4L60 it replaced, before I added the deep pan. Adding the deep pan mostly added fluid weight, because now it takes about 13.5 quarts of fluid to fill.
The 9.5" Vigilante should cut a couple quarts out, because the Hughes converter I have now is a 12" monster.
Love the programmability - Grandma mellow around town until I hit 47% TPS (where my secondaries start to open), then I have it set to neck-snapping shifts and lockup under WOT. And it's delivering a solid 20mpg, too.

FWIW - I have ~ 5500.00 in my 80E warranted to 1200 HP from Gear Star. Ive only hit it w/ ~ 800 so far but its been great. On the street rolling @ 50 lock the converter and grab both kits = lots o fun.
Back on topic though,
You really cant go wrong either way 400 or 80e. I would say its about 30% less money to do a 400 vs 80e assuming all the exact same upgraded parts. The 80E will eat approx 2% more power and will weigh ~ 65lbs more.
I just shipped my 80E, Yank PY3400 & HGM Compushift electronics back to gear star for a full manual valve body conversion and the un-crated weight was 260 lbs w/o fluid (Drained as much as possible w/o disassembly)
I've had 3 different 60E's, a RMVB TH400 & now the 80E in this car and Its a real toss up between the 400 & 80.


wow, I am with above on that one, 8's for a th400
