Torque Convertor??

[GAD]

I have a TS stage 3.2 VVT CAM. I went with what Texas speed recommended, Circle D 3200.
I’ve yet to race my car, but it is my DD and I hate the stall. I’m going with the 3.91 gears within a few months. Maybe that will help. But right now in my DD scenario it just feels like I’m screaming around town at the speed limit. No cruising at under 2500rpms. Can’t even use 6th gear below about 65mph (I think that’s due to my cam). Mild/normal daily driving isn’t fun. But hard pulls and breaking the speed limit is now twice as fun and 3 times as easy. I still wouldn’t give up my cam to go back to stock stall.

That's weird. Mine is noticeable at part throttle but nothing crazy. I did ask my tuner to make sure the converter is locked up as much as possible at part throttle and light loads to keep a stockish feel while driving and unlock at WOT.

I wonder if that is as much your Cam as it is the Stall? I bet the 3.91's will help.

3200 is too tight for that cam. It needs 3400 and above. I know this because I have 3.91s and that same stall. You're leaving performance on the table, I'm switching to a 3700 this winter.

His tuner sucks. I have the same setup with 3.91s and it's fine for dd. The stall is too tight for racing use however. And hopefully he out an auxiliary trans cooler on or he's just gonna burn up his trans.

GPI SS1 VVT Cam with all supporting valve train goodies.

This will be a STREET CAR ONLY. I have never had an automatic Hot Rod before only Manuals. So my experience with Torque converters is basically nil. I know this Cam can be run on the Stock Converter So??? What are the benefits and disadvantages going with an aftermarket converter?

If I decide to go with an aftermarket converter which Stall Speed?

3000-3200?

3200-3400?

3400-3600?

and Why???

Will it affect Streetability and how??



Thanks!

Dan

Go with what they recommend. Not what the internet gurus do.

Link to idle video.

Thanks!!! I appreciate the time you took to do the video for me. I Love the sound! I think the LT Kooks with Hi-Flow Cats, GPI SS1 VVT Cam, and Borla S-Type Cat Back Exhaust should give me the sound I am looking for without being overly obnoxious (been there done that)
I know the performance I am looking for will be there. Just a little teeth in the bite.
So did you get someone fairly close to you to do the install and tune? I have not found anyone within 200 miles of me that is supportive of the VVT cam. You like yours?
I just have to figure out a way to get mine to Little Rock for a week so Ryan and the boys can do their magic.
Thanks Again!!

That is probably the Best advice anyone could give. I do like to hear what people think from hands on experience in their own DD. Not necessarily what they think because they think they are a Guru!

In my DD experience, I went with a circle d 3B stall. 3200-3400. I have the vvt 3.2, supporting mods and 3.91 gears. The car seems to have tons of power. Seems being the key word here, because my 60' times are almost identical with 20" all season tires and 17" drag radial pros. After extensive trans tuning the results were the same. The stall is simply to tight. The better choice would've been the 3400-3600, and that recommendation came directly from circle d. I am boosting mine next yr and they recommended the looser 3700 stall, any competent tuner can make these cars drive like stock. Mine drives pretty well, aside from the occasional lunging at low speeds, once again due to it being too tight.

Mean, you NEED a better converter with the L99...if you don't you are doing it wrong.

I definitely plan on a Stall. I am sure the Boys at GPI will steer me in the right direction. I wish they were closer but I will deal with it one way or the other. I just did not want to create something that was a PIA to drive on the street. Like I said I have been there done that before. These Computer tuned engines and automatic transmission cars are something totally out of my wheel house. Now my 80, 4 speed Corvette with a Roller cam, Holley fed , 383 Stroker. I can Handle it. If I have a need for more Noise and Power I can just hop in it. Not much of a Cruisin car and definitely not a DD.

I did the install in my two car garage. I went with the SS1 VVT cam and a Yank 3400 power adder stall. Got a base tune from GPI and then had it Dyno tuned at Futral Motorsports. This winter I'm installing a Vortech blower from ESS. Yes I really like the cam, especially with the stall.

That's a trans / converter tuning issue.

I ran the TSP VVT 3.2 cam with Circle D 3200-3400 sigle disc, TFS GenX 255's, Full Kooks LT's and 3in exhaust, e85, etc., and it drove fine as a DD.

I now run the Circle D billet triple disc 3200-3400 with ProCharger.
