does anyone know where i can get some info from people running one.

 

Does it have to be rotary specific powerglide info?
If it's just info on the transmission itself (and not how the car behaves) then I'm sure you can get TONES of info on some Domestic car forums out there.

 

rotary specific. i would love to go auto on the pro mod car but i just need more info.

 

found www.fbperformance.com any others out there

 

I'm doing a PG behind my 20B. Unfortunately it is all experimental, and not running yet, but I might be able to give some pointers. There are some nasty 'gotchas' with this conversion

Gary.

 

i just talked to a guy using a powerglide on his super gas gto with the same diameter tires 31" using 4.88 gears. he uses a 6500 stall, he says he leaves at that rpm shifts at 7400 about past the 60 foot and finishes off redlining at 8500.

 

Some of the things to think about for a PG behind a rotary are:

Bellhousing: either an adaptor plate (available from ATI for a measly $900) or customise the rotary auto bellhousing. I have done the latter because I had a couple spare and I am 20B so using a front mounted starter. You can't use the rear mounted starter of the 13B because there is insufficient room between bellhousing and trans for it. I had a 1" plate welded to the rear of the bellhousing and machined to fit to the PG pump bolts, the same way that an Ultrabell works. I had the PG case trimmed and trued.

Converter: Custom made to suit PG spline and rotary flexplate, or get the ATI adaptor plate and flexplate if you want to save time. I am using a 9.5" 5500 stall PG converter and will be making my own adaptor plate to mount it on the rotary flexplate. You have to be careful with converter heights when you do this.

i run a TH350 in my car, the PG is too unefficent and requires more torque. behind a three rotor it will be ok but on the 2 rotor you will not make enough torque to take advantage of the TC. the pump on a PG uses way more power than a TH350 ( about 10%more) i use a chevy 6500 stall 9.5" convertor (that only loses 5%), chevy FW,chevy starter mounted on top of the engine and cheetah shifter. for the first 75 ft i have a 2.65:1 torque ratio which basicly multiplies whatever torque the engine makes by 2.65!! but keep in mind the TH350 is only good for around 800ft/lbs of torque any more than that you will have to go to a 400 or PG.

turbostreetfighter: that's the setup i'm going with.....did you make your own adapter? I haven't set it up fully because of other things going on.....but did you have to alter the tunnel? Or is your car full chassis?

 

yeah i made my own adapter and it was a BITCH!!! the starter has to go on top so a custom manifold is neccesary. holla at me before you buy a convertor, i am sponsered by the best company out there for effecient convertors. i did not have to alter the tunnel(although it is a tight fit) my car is only backhalved.

 

turbostreetfighter did you make they adapter complete or modify a stock rx autotranny.

 

That is great news! I will hit you up for sure I've got everything handled now except for modifying the driveshaft
