SignUp Now!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?![]()
Anything under 20%What do you consider minimal slippage?
What do you consider minimal slippage?
Acceptable 6-8%
Awesome 3-4%
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![]()
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
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.
