Circle D or Suncoast

[Gregory347]

Go big. Imagine how close you’ll be to a 9 second slip with a 1.4 sixty.

That’s the direction I’m leaning... Ran at Atco yesterday... not typical November Atco conditions was 74 degrees. Car ran 1.68... 10.48... 136.25... and 1.68... 10.49.... 135.5.... 2 best runs..... I think the converter and some MS109 in the tank can get me a 9 second slip.

I predict the converter alone will be worth 3/10ths. I’m waiting for that perfect weather to take my stock 19. I’ll probably hit Cecil. The $100 fee Atco has been charging is stupid high. I’m predicting an 11.7 stock run.

Circle D worked out great for us on Project Goldmember. Was able to cut a 1.27 60ft with it using a 2nd gear leave. This is a magneride car too. Went 8.60's consistently with the car.

We carry Suncoast as well but I've never personally used one to review it.

Feel free to give us a shout if you have any questions and we'll be glad to assist you.

Have they fixed the issues with the Circle D converters?
I know several people who had issues with the one for the 10r80.

Mine broke after a few passes . I did cut a 1.2 60 the first pass but looks like it broke that hit .
Circle D were great and I was able to get a refund (minus restocking fee from the vendor ) .
I know of the car below (turbo car ) that is consistently 1.3’s off the foot brake ... second gear leave tune .
I am sticking with the stock converter (at least until it breaks ).

Olaosunt.... nice numbers.... I if I had 200 more rwhp I’d probably cut a decent 60 foot and stay with the stock converter for a while.....

seems like the Procharger is lazier down low then the Vortexh/Paxton.... they seem to do a bit better with the 60 foot times.....

That's a very general statement....

i wish but not my numbers

based on 60 foot times of other members... stock converter.... any suggestions.? Tune?

There is just lots of factors to consider. That may be what your searches indicate, but to say paxton/vortech 60ft harder or that Procharger is lazier down low as a general statement is not true. As far as current centri setups on this forum, Procharger is king. Fact.

On stock converter, it seems my best 60 came from stomping gas pedal from idle vs trying to bring rpms up on converter. Try both and see what ur car likes.
