What are the advantages/disadvantages of this converter? I know there are converters rated at a stall of 3200? And put out 3500? What would be the perfect stall to complement 3.73 gears, good gas mileage, VERY streetable, and will pull like crazy at the track. I go to track maybe 3 or 4 times a year, and drive hard on the street. Also, after torque converter, I plan on a supercharger. Would a Torque converter be too much off the line power? Should I get one or not? Please help.

 

You get great launches with the vig3600. I have seen short times of 1.5's in the 60 with the vig3600. They pull pretty hard, but they are not as efficient as a Yank or TCs in the higher rpms, so you wont pull as hard on the top end or mph as high. But, you sure will 60ft like a mf'er and run a great time. They are well built. I had a vig in my 94 vette. If your worried about doin the sit n spin at launch, just get a TC with a lower STR. You wont 60ft as well but it will pull better on the top end. Lastly, by all means GET a converter. It is the best mod you can do for a A4! Right now I'm torn between the vig3600 and a TCS.

 

Hey, sorry to sound stupid, but I am on day one of converter research. Please give as much info. as poss. What do you mean by not as efficient as a yank or TCS? What is a TCS? Also, I'd prob. rather my power be in the higher RPM's, that would help me on the highway, where I do most of my racing. See a viper, or vette or whatever, and hammer it there. I only go to the track maybe 4 times a year, so yes, I want it to help me at the track, but my car is not only a track car, but mainly a daily driver. What is STR? Thanks in advance.

 

Wow! In the twelves already w/o a converter! STR=stall torque ratio...a measurement of how much the converter multiplies torque being fed from the motor. The higher the number (stock is @ 1.8) the more torque. But, a very high STR means less "efficiency" at the higher revs(above 5k rpm)...hence lower trap speeds. So a high STR ain't the end of the search. If you are already cutting 2.0 sixties I don't think your gonna need much of a STR to shave 3-5 tenths...2.1 STR on a 3200 stall would probably get you there and be killer on the street with your gearing. Some would probably suggest as high as 4000 stall from what I've been reading but your streetability would be compromised IMO.

 

You all seem to know about this stuff. I could use yyour help. I want to got a converter but I do not know anything about them. I have a 2001 SS A4 3.23 gears, with basic bolt-on's. I have not been to the track so I do not have any #'s to work with. I was looking at a 3200 stall but I do not know about STR? I think thats what it was. What do you think would go good with my car?

 

They are a site sponsor to the right under RAMCHARGERS---->tHEY CUSTOM BUILD tc'S TO YOUR NEEDS/CAR SETUP. They are very well built. Run 689.00 through Rapid Motorsports.


The lower STR yanks and TCS' are losing half the HP that a VIG3600 does on the dyno(all bolt-on vig cars can lose like 28hp to the wheels). You will notice that from a 50mph hit, in a 1/4 mi no biggie because the 60ft is so good. The TCI's and Midwest also make great TC's for low $$$, but don't seem to put up quite the numbers that vigs, yanks and tcs's have been.

 

heres some info for you. iwent from 12.90s to 12.00s with torque(vig3200) and hooker long tubes. its not as efficent as others but like they say that doesnt matter at the track.if i ever changed my converter i would only go with bigger vig(3800). jason

 

If you're wanting to go from a roll, the Yank Thruster Pro 4000, 4200 or better yet, 4400 are the best. They have a high str, so they are also awesome at the track. However, with the higher stalls, they are very 'loose' feeling when driving around town, so that is the tradeoff. If you're not prepared for it, in a daily driver it could get really annoying in traffic, especially if you have a loud exhaust.
