the power numbers are on point. Afr looks a bit funny. Have your tuner street drive it, go from there

 

That's actually not my car. I was just posting that as a reference for something similar to my setup to get an idea of what stall speed would be good.

 

Full 100% agree. I would take it to 6900-7000 ish. Edit: nm its a 98 so the 6700 may be better

That converter is FUCKED. It's acting like a near 5k stall.

I had a yank SS3800 with 3.73's and it didn't act anything like that. I could roll up to 40 mph (and beyond) at a much more rapid pace than you did without going over about 1500 rpm. You were up near 3k and barely hitting 35 mph.

I believe the fins are rolled over in that converter.

 

Restall time.

 

Hey man, go out and put the car in second gear at a dead stop, hold the brakes hard and rev it until it either pushes through the brakes or starts spinning the tires... or until it just stalls, that's where it stops building rpms when on the brake. What rpm is that?


I have a strong feeling it's going to be way high.

Hows your trans fluid? Is it full?

And lastly, are you running street tires? If so you better put drag radials on it before you put a good stall in it or that pretty *** car might be wrapped around a tree. I'm serious man, my car scared the **** out of me several times with the stall on street tires, because it would some times blast the tires off when I wasn't really ready for it. And I was running 315's too. They were still worthless. Had to run drag radials daily. You can run street tires, but be ready for it to be an absolute tire frying handful.

 

I'll give that a try sometime this week. In the WOT vids above you can see I'm almost to 3k and it's not breaking the tires loose but that's in 1st gear obviously (in D).

Just checked trans fluid the other day. It's full.

Yes running street tires and rear wheels are 20's so that doesn't help. Tire size is 305/25/20....11" wheel. Were you breaking them loose at higher speeds too? Say 55 or so?

 

kinda.. depends how I hit it. but I was also bolt ons only.

1st gear was useless. It would hit second and blow the tires off, sometimes if I hammered it and it downshifted to second it would spin sometimes it wouldn't.. I could do a roll on by holding it in second until 50 or 60 to hammer it then it would hook.. usually.

But you have a cam and I didn't. It's gonna be worse for you.

 

It's been 10 years but if I recall correctly the SS series is supposed to have a 97% efficiency rating, if that helps you at all. I don't know how to get to the percentages you did (the math)

and I'm assuming he has a SS

 

Sctick

Yours is slipping really bad. Listen to 98cayenne's video and this one (this is the only in car video I have of my car). 98cayenne's stall is a 4400 and mine was a 3800. On our cars you can hear it shift and actually drop rpm and pull up through the next gear.

Then listen to yours it just sounds like it stays at one rpm basically, and you can't even hear yours shift to second its slipping so bad it just all kinda sounds like one gear.

And in my video my trans was trashed, it only had 1st and second gear and it was having a hard time shifting from 1st to second to (slow shift) plus we were drunk af at 230 in the morning lol.

 

and in the WOT videos I can't tell that it ever shifted to second, it sounds like it started in second..?

 

With a 4l60 3.06 first gear, 26" tall tires, you'd be at 6048 rpm at 41 mph in 1st gear, so that shift at 55 is second gear

You should be shifting out of 2nd near 80 mph because with 26" tires and 3.73 gears and the 4l60 second gear ratio of 1,625 you'd be at 78 mph at 6110 rpm (that's with 100 lock and the converter is still slipping a little bit so a few mph off here is fine but you're about 20 mph off)

But you were at 6100 or more at 55.. so its just slipping like crazy

 

I think instead of talking restall for your converter you should be think rebuild. It certainly appears you were sold a bad piece.

 

Yeah it's an SS3800....or at least it used to be.

Yeah I can tell from you all's videos that yours shift way different than mine. My car has always sounded like it never shifts at WOT since I put that stall in. So thanks to the ******* that sold me a toasted stall.

Like I said in an earlier post, as soon as I hammer it, it obviously starts roasting the tires. So I when I let out of it a bit I assume it also shifted from 1st to 2nd.

 

When you send a converter off to be restalled does it not get rebuilt?

 

a "restall" isn't the same as a rebuild. I can bend and cut fins and totally change the converter characteristics and never replace a part.
However while a converter is apart for a restall anything that is noteworthy to constitute a rebuild should be easy enough to see and act upon.

 

I see. I'd imagine there's a price difference between a restall and a rebuild then?

 

What the hell is a "stall"?

I didn't know such a part existed...

BTW... The guy from FTI that Chimed-in, is Dalton.
I would him him a call up asap.

 

Op, I also run an FTI converter. I can’t recommend these guys enough. Best converter I’ve ever used and I have used other brands.

 

I've heard good things about them.

 

Uh oh, PC principal in the house
