What converter will give me the best trap speed?
I have a Yank 2800 converter now. My trap speeds seem kind of low. I have all the bolt on's (except a pulley). I have LT headers and a 224/224, .581"/.581", 114 LSA cam. My trap speeds are around 112 mph. I think it should be a little faster. Maybe I am wishful thinking.

Well the key is to get your average RPM through the ¼ mile run higher. With a 2800 stall and 3.23 gears you should be dropping to ~3800-4000 rpm after each shift (aka shift extension).
If your car is mainly a daily driver with little track duty then I would go with a TCI Super Street Fighter 3500 converter. This converter will give a ~4300 shift extension. If your car is mainly a track car then go with a TCI 4400 converter. This converter will have a shift extension of ~5400 rpm.
Both converters will give you better ¼ times.

Full weight 2000 T-top Z28 lid cutout 3.73's and the SY3500 trapped 109mph. No weight reduction whatsoever. I'm selling the SY3500 since I went with a manual...PM if you're interested.

I also had a driveshaft loop and drag radials...but that's it.
*Edit - If you're looking for a setup to 60 foot better than the 1.7X range, then this converter may not be for you. My best was a 1.82 on nittos. I really think I could cut a better 60 if I had more power or played with the air pressure more...but this converter is more of a compromise for racing on the street and at the track than purely track. I don't want to give you any false impressions since 500 bucks is alot of money to throw down. That being said it is a great converter and if you like to put the power to the ground on the street...i'd recommend it.
