Vig 2800 or Vig3200 ?
I daily drive this car mostly on the freeway (about 40 miles round trip) , this car is only used on the street and does not see the track. I'd appreciate any opinions (good or bad I don't care) about this convertor/cooler combo.
- How are these verters in a highway race (say 60/70 punch) ?
- Will I lose any top end ?
- Is adjusting the shift points really necessary ?
- Will I lose mpg in the city/highway ?
- Any lockup problems (if so how often) ?
- Which B&M is tried and true ?
- Will the lack of downshifting be eliminated or atleast decreased (i.e. 35-40 & 55-60) ?
- Does the feel of either of these verters (highway or city) feel anything like the stock verters ?
Thanks for your help.

Both converters are nice in a highway race. The Vig 2800 is more efficient than the Vig 3200 is, so it should fare slightly better on the highway.
Will I lose any top end?
No, you won't lose any top-end w/ either converter over the stock unit. You will gain MPH with either converter.
Is adjusting the shift points really necessary?
It's really a hit and miss situation w/ limiter problems after a converter swap. I didn't have the problem on my SS for a few months after the converter swap, but it did start tagging the limiter on the 2-3 shift eventually.
Will I lose mpg in the city/highway?
This varies greatly from driver to driver. It basically depends on how heavy your foot is. The guys with lead foots are getting as bad as 10 MPG in town. However, I saw a consistent drop of right around 1-1.5 MPG in town w/ my Vig 3200. I'll average 15-16 MPG w/ all in-town driving. Highway mileage won't be affected since the converter will be locked up.
Any lockup problems (if so how often)?
The only time I've ever had a lockup problem w/ my Vig 3200 was driving on the highway when the temp was in the 40's. I drove 280 miles that day, and it only happened once. The trans temp apparently got too cool, and the PCM locked the converter up to generate some heat. It was unlocked for a total of 20 seconds or so before it locked back up. This is once in the past 7 months.
Which B&M is tried and true?
The B&M 19,000 GVW Super Cooler will work just fine for you. You can check with Thunder Racing on this unit. I know that Summit Racing also sells the B&M coolers.
Will the lack of downshifting be eliminated or atleast decreased (i.e. 35-40 & 55-60)
Both converters will just about eliminate the dead spots that you have with the stock converter. As you know, getting stuck in the bottom of 2nd gear w/ a stock converter leaves you dead in the water in a race. The converters will help that out a lot.
Does the feel of either of these verters (highway or city) feel anything like the stock verters?
I've had both converters, and the driving manners between the Vig 2800 and 3200 are nearly identical. You can tell a difference from stock, but it's nothing major that will annoy you by any means. The Vig 2800 is just slightly tighter for driving compared to the Vig 3200, but it is definitely negligible. You said that you never go to the track w/ the car. The Vig 2800 will hit the tires softer than the Vig 3200 would, so it will be easier to launch on the street. The biggest ET gain between the two converters at the track (assuming full traction) is in the 60' times. The Vig 3200 nails the tires harder, allowing for a quicker 60' time. I don't know how much added shift extension you're going to get with the Vig 3200 over the 2800. Maybe you can find someone with a Vig 2800 and 3.23's to see what their RPM's drop to on the shifts. With the Vig 3200 and 3.73's, my RPM's drop to right at 5,000 RPM on the shifts w/ 6,200 RPM shift points. With 3.23's and the Vig 2800, I'd guess that you'll drop to 4,400-4,500 on the shifts. Don't hold me to that since it's been a few years since I've had a Vig 2800 in the car. A current Vig 2800 owner could better answer that question.

This is exactly the information I was looking for.
