I am thinking of running one for the 400.. heard nothing but good things about them. Good quality pieces, minimal slippage..
Anybody here have any feedback that has or is running one?
I have one in my th400. My new Bradco (put it in about 3 weeks ago) spools great (enough to redlight:redface: ) and has minimum slippage at the top.
I ran one in my old 200r4 too. I replaced a pos PATS converter with a Bradco in that tranny. I broke the stator twice in the PATS, never had any issues with the Bradco. You get what you pay for.
Anything under 20%
Otto. what do you consider minimal?:smile:
6450RPM-28"tire-3.42 gear-1 trans ratio-151.99mph=3.40%
This is the info from my last convertor
Im using 6450 as RPM as it was the highest in the datalog.
It could have quite possible been 6300-6400RPM
making it even more efficient
Best of all it spooled an 80mm non bb on a pro tree no problem.
After just looking at Dicks record setting datalog his was about 6.20%
By my calculations

Whats weird on my car, which has been dead consistent all year with over 100 runs, is that I never gained any mph from going with a converter with 18% to a converter with 8%. The only difference has been what rpm I'm at through the traps.
Time to find more power
Turning less rpm thru the trap is also better for engine longetivety

Working on that power thing
I have a few things holding me back...it's just a money thing, or lack there of
But I'm only turning in the low 6000's through the traps. 6% is only about 200 rpm's for me.
BTW, what do you estimate tire growth as for 28x10.5 m/t's? Adjusting by 1" makes a huge difference in percentage. TCI - TECHNICAL INFORMATION: Racing Calculators

Otto used driveshaft speed to calculate his. I saw those passes. No doubt about the PTC units. If your slip went down 10% and your mph didnt go up on the same tune and ambient temp id say your turbo is out of breath.

Bradco Bolt together
I have a Bradco alum bolt together I bought from Kip @ Excessive Acceleration (who is a Top Gun Point series sponsor).
This weekend at Atco we were 7320 in the traps with a 28.5" tire, 3.70 gear and 162.45mph which is 3.3% according to TCI's website. At 161.98 mph we were 7230 which is 2.32%. Earlier in the year in the mid 150's and down on power we were less than 2%. With the new Extreme automatics cam we can spool a PTE88 without the VSC and race on a protree with this converter. With the old cam profile it was difficult without the VSC. Chance PTC adn Bradco all seem to build quality stuff so I don't think you can go wrong with any of them. I went with Kip and Bradco because of the service and willingness to "get it right" without a lot of additional expense.

I have seen a Bradco, sure looks nice....
This is great info. Those units are definitely working out well.
