Please help pick a converter
Our other car is a GTA with a very similar build. The main differences are,
1. The GTA has a Torquer 2 cam on a 114 +3, compared to the SS having a TSP 233/239 on a 112.
2. The GTA has an Edge 3,200 stall that was hitting dead on 3,200 before the upgrade to a Fast 92 intake and PTM 92mm t/b. It now hits around 3,420 rpm off of the line.
The Camaro MUST get a new converter because the Vig is just way too loose. I mean it's just stupid. It gets away from lights ok at part throttle, but anything over maybe 20 percent throttle and the slip is irritating. It makes the GTA's Edge converter feel stock. That I could live with BUT, at a 65 mph kickdown it is night and day. I would have expected the SS with its big Vig to walk the GTA but it's not even close. The GTA instantaniously kicks down and literally jumps 3 or 4 car lengths to where it slaps 3rd gear at just under 80 mph.
Flooring the SS at 65 mph results in a shift down to 2nd gear and a whole bunch of noise but not much else until after it hits 3rd. Even then it just feels like it's pushing through the converter, all the way to redline. It's like being in a stick car and keeping the clutch pushed in far enough to waste about 1/3 of the power or more.
The solution for me seemed obvious; Get an Edge stall for the SS also. I figured since the SS is 200 lbs heavier, maybe step it up to a 3,600.
But now I'm wondering what you all think because some guy,
Frank Cahall of CPT Performance in Delaware, says on LSX parts for Sale, that Edge Converters are complete crap and usually don't last 2 months before tearing up the transmission.Who knows what's up with that?
Anyway, we want a converter that is a good dd, but can get great numbers at the track. I know that's what everyone wants.
I have been eyeing Circle d for a while now, maybe a 5c if it would be tight enough on the street.
The GTA makes 445 rwhp (open cutouts), runs 11.20 at 120 in a 20 mph headwind and 150 da and with a 1.61 60 ft (that pass), and gets around 19 mpg when we drive like very old men for most of the tank.
The SS mad 428 rwhp (no cutouts), runs 11.6 at 119 in 2,770 da, on a 1.8 60 ft, and gets 15 mph.
I know this is a lot of to answer but please just address what you can.
What converter would you go with? It doesn't have to be one I listed. Please explain why. I just need some others' personal experience here, as I have very little in this department. I only want to change this converter once. lol
I'd look very closely at a PTC 3600 or an SS3600. Those have proven records. I talked my buddy into a PTC3600 (based on Lemons suggestion) and then tuned the car and I was impressed with it overall. PTC has a stellar record of happy customers. Otherwise, I have no doubt Circle D or FTI could build you what you want also.
That being said, Chris at Circle-D makes a fantastic converter and will restall free if you miss on the first try. I know a few guys that say Chris s converter MADE their car. Just don't cheap out with a 400 dollar mud bucket and know what you want before you drop the funds and you will be happy. Good Luck!
