Converter company suggestions for my application
 

I'll put the car back on the track w/ the current -- and old -- Dynamic (Lupo) 9.5" piece that was in the car previously to get a baseline w/ the new engine combination. With that combination, it would flash to approx 4500 from a 2000 launch and showed about 8% slippage on the big end (1/4 mile).

Being a dual-purpose car, I don't presume the converter can be set "on kill" and still actually drive the pig to the track. However, my expectation is I'll be getting recommendations to go w/ a tight 8".

The torque peak's moved up from about 4900 to 5100, and the HP peak has moved up from 6300 to 6800. Power-wise, the torque curve has picked up across the full 3500-7200 dyno pull range and the peak HP is is up about 60 HP. Trap RPM will probably increase from 6800 to maybe 7200 now.

It's a BB Mopar (440 stock-stroke), and a number of BBM bracket racers were using Ultimate w/ good results before Lenny sold it (to one of his former employees, IIRC).

I really don't have any complaints w/ Dynamic based on how the 9.5" has performed, but they haven't even updated their website in 10+ years. I have no sense for what they're doing today or what their rep is now.

Have never used ATI, but I could drive there from where I live in Northern Virginia and talk to them face-to-face, if a better approach than over the phone. I have talked w/ their reps at the track, but not in many years.

Also not against going somewhere else, so any feedback or thoughts as to what converter company might have a better handle on a combination like mine is appreciated. FWIW, it's approx 3800# w/ driver and should pick up noticeably over the old engine that was good for mid-to-high 10s as driven to the track.

My apology if this post seems to bounce around in terms of how info is presented. Thx - Brad

FYI, I also posted this under the Bracket Racing forum, in case that's considered more appropriate. However, that one doesn't appear to get much traffic, based on the dates of the most recent posts. Thx

Talk to Charlie @ ATI he is very knowledgeable. My stuff seems to like the ATI stuff.

Lenny is still at Ultimate, they moved the shop to S.C. and Lenny is staying for at least a year or so until Montgomery has a good feel for what he's learning from Lenny.

I have a Dynamic 9.5 in my street car, last winter I had Dymanic update and tighten it up. It works great and is very streetable. I dealt with Sean, good service reasonable price.
Any of the big converter builders can build what you need. Dynamic was always good with bb mopar stuff. I have had good luck with an ATI in my small block stocker.
I think Dynamic and Ultimate are small operations and you get more personalized service, ATI is more of a big business, but good quality parts.

Ultimate is still a good choice. I have bought several converters from Ultimate and all perform as expected.

Ultimate Converter has done nothing but impress me since meeting Lenny & Dawn at the former location. I met Montgomery at PRI and recently paid him a visit at the new home of the business in SC. He’s learning under the watchful eye of one of the best intuitive builders in the business - Lenny called to check in while I was there. Bottom line is, give them as much valid data as you can collect to give them the best opportunity to make you happy. :)
