What size converter?

[Clark6]

Brother has a 3400 9 1/2" lock up (new) in his 200r with a mere TE-60 he's just coming from a 8 or 9 inch OLD rusty Art Carr original NON lock up. Trans started flairing after his engine build so he had it rebuilt with a new stall (Edge).
A reputable shop did the install shifts perfect light throttle.

but from a dig its a dogg. it hesitates about 3-4 secs then it pulls like a bull. The tranny does have the lock up solenoid & all needed for the change over but his hole shot is killing him! any suggestions? the turbo is gettin some age on it but it spooled fine before the swap, and was just wondering if we picked the wrong stall. he has alum heads, 60 inj. 212 comp roller. 28"mt.
oh yeah the last stall was a 3500 or 3600 non lock Art carr Wonder if we need to put it back in?.

Tryin to figure if its the stall or the tune. the Maftpro (which was also installed the same time as the trans) looks fine as far as set up specs. which had us wondering about the verter. In the yard or on the street we hold the brake to the floor and it starts pulling the car forward around 2700-2800 rpms if that helps anyone.

Converters require some black magic and voodoo to get it right the first time around.... Just MHO.....but I've been through quite a few conveters.

I'm not a big fan of the Art Carr n/l.....they work for some guys, but it did not work for me. Yes it spools easily, but the top-end efficiency was lacking. It somewhere in the 17% slip range for me. My PTC is in the single digits.

From what little I know about converters.....you have the wrong stator. It usually determines the "low-end" of the converter and how quick it spools. You may still have good top-end efficiency (or maybe not ???) but without the right stator it will spool like a pig. Been there, done that. Usually hte pump vane angle detemines how efficient it is up top. But again, it is all a combination thing, and every car is a little different and and off the shelf conveter will not hit it right on.

Ray I didn't think about on the phone fri. Take the Trans Pro off and that will eleminate that wihout a lot of tweaking on the Trans Pro. I would like to believe it's not the conv sinc mine,yours,and Kris's were dead on.

So the new motor was tuned fine and killing the old trans/converter set up until you added the converter or along with the Trans Pro??

Second, Edge converters are hit or miss in all the threads I have read about them and yours sounds too tight if it's pulling you through the brakes at 2700 - 2800 rpm, that's pretty much a stock stall rate.

It does sound like a tuning issue, what is your af/r at the foot brake or your BLM if you have a GN scan tool??

And an 8" Art Carr is way too much for a TE44 and I would like to see the efficiency up top with it. PTC does seem to be the new kings of non lock ups for us.

It's his brothers car,has a 60. I think the conv and trans pro was all added at once. The car ran 6.80 in 1/8 with ac9" 3500 and a TE63 with the previous owner. I may run over there tue or wed while I am off.

Update:

FOUND the problem thanks to all.

he had 2 leaks: one on the back primary tube of the passenger side header (old atr). the other was at the connection point of the crossover.

fixed both leaks now turbo spools like a ball bearing.
spin the tires about 20 ft.

Moral of the story is FIX ALL HEADER LEAKS first then tune. The stall is fine, now he needs a bigger turbo:biggrin:

i had the bleeder valve on there & it wouldnt spool past 19psi even wide open on the ext. wast gate. took it for a spin instant 27psi . now im gonna put the boost controller back on. & turn things down abit.

just wanted to update what happened, i dont like post where no one go back to repost the results even if it take months to fix or locate a problem.
