Looking to drop my ET, the first half of the run is a little off, I am currently using a B&M holeshot 2400 that flashes to 3200 behind my 448ci 440. Car and driver go 3860lbs. Currently running around 11.3 120mph with a best of 11.27 @ 121mph. Like to drop my ET into the 11.0 range. I hear all the usual suppliers mentioned here, I also hear the main guy has retired sold the business etc. Has anyone had any recent experience with the likes of PTC, Ultimate, Dynamic or any other known mopar gurus.
 
PTC out of Alabama. Excellent product, very helpful, nailed my requirements 1st time on 2 orders. They have a great rep. My experience was 5 yrs ago.
 
I feel the best in the mopar world is frank Lupo dynamic converter Newark Delaware they will test the converter on a converter dyno and is a very experienced mopar racer as well

I’m interested too. I have a generic 11 inch 3000 stall that I have only ever seen hit 2600 flashed. Doesn’t matter if I hit it in 1/2 or 3. Full manual shift. Best was 3rd gear roll hit from 2200. It flashed 2600 then climbed from there. I’m thinking a 9.5 would be lighter with lass slip on top.
 
I just switched from a Dynamic 10" that flashed to about 3500 and put a 9 1/2" in from Dynamic.
The car is about 3700, race only. 10" times 12.40 @ 109 9 1/2" 11.94 @ 111
Shawn told me it would be worth about .4 and he was dead on. I know there is more in it, need to tune shocks, jetting etc.
Frank and now Shawn have always done an awesome job, and great knowledge. I also have a Dynamic rollerized 727 in the car. Personally I would not go anywhere else.

Hope this helps, Jim

Dynamic is a good place to go. My 8" from them flashed 5400 just as i requested. Dont over look Dice convertor. That guy know his stuff as well. Just spoke with the guy at Dice yesterday and he says he can make my 8" work behind my new 572 Hemi combo(currently behind my 511 wedge). He told me something interesting, That mopars are different at where they make peak torque. Not at the hit, but generally at the 60ft. So, you need to be careful with stall to not blow thru them.
 
Dynamic 91/2 here also. Flashes to 4500, goes down the road 2100-2300 @ 55-60 mph with gear vendors and 4:30's
 
Dynamic or PTC is what I have run with several of my more recent cars. Currently have 3 PTC's in 3 different cars and a B&M in another car. Then just production 440 converters in my more stock/original cars.

Sounds pretty good, what is your trap RPM and MPH, and what size tire?
Click to expand...
Trap RPM 6600-6700.
132 MPH.
28" x 10 Hoosier QTP.

Drives in city traffic almost like a mild mannered car. Very snappy though and just noisy exhaust which is good in a city with thousands of distracted Jaywalkers and drivers.
