Who would you have build a 8" converter for a strictly drag car? I currently have two 8" that were bought second hand, but one is broken now. Can someone just repair my broken one and have it changed to suit my build, or am I better off just starting over?
 
Yes it can be repaired and redone to your specs , a new 8 inch is over $1,000 in most cases , a rebuild is less than half that. I use and recommend Ultimate Converter Concepts 843-264-5448

Thanks for the suggestion. I will try and call them this week.
 
Did Lenny used to be a part of Dynamic?
 
Does anyone else have a suggestion? In case they don't call me back.
 
I still have 2 727 Ultimate 8” converters. One would 60 in the 1.24-1.28 range. The other slowed the car slightly, but produced a stack of 1.34 60 times making the car more predictable than its ever been. If I hadn’t gotten stupid and sold my 727 I’m at the point where I’d put it back in. We’ve been 1.2s with the 904 and 8”.

And that's what I'm trying to do, make the car more consistent. Right now it has a turbo action in it and one pass it will go 1.42 next pass is 1.45 which seems to be effecting it on the other end. Whit the converter that is broke the car was 1.52 far more than it wasn't and it was pretty consistent on the big end.
 
So I called a few places today, coan and ptc. Coan said since it isn't theirs all they could do is rebuild it, not do any adjustments. Ptc said they can make the changes I'm looking for.

Kenny worked on my Ultimate, good guy to deal with, races a Mopar too.
 
The last convertor I had repaired was by Jason at QuickDraw, he seem to work on any brand. Some companies will only work on their own. The 2 new ones I bought have been a Trans Speciaites and a ATI. Repairing a broken one is typically around half the cost of a new one depending on what's broke.

PTC sent me some pictures of the broken converter. I thought they were cool so here you go. He said it was from metal fatigue and bad furnace brazing.
