I posted in the Drag racing results forum but wanted to throw a quick kudo's out to Performabuilt transmissions and Circle D converters here. Absolutley awesome performing stuff from both companies. Circle D put my car on the bumper and the 4L60 Performabuilt shifted like the bricks! 405 SAE dynojet RWHP (stock shortblock) and a 1.31 60' 10.14@130.9mph.

Thanks to both of these great vendors

 

Nice I like that 60ft

 

That 60 is moving. That was the first time out, I bet there are some 1.2's once you get it dialed in and dare I say 9's??? This is a new converter combo we are working on for NA motors, more info is coming. Here is the link to the drag racing post.

Thanks you for trusting us to build your converter, we appreciate it!

Wow 1.3x 60ft thats pretty good what size is the verter?

 

XXX2 I'm looking to up grade my tci after christmas..
Is it the 5c ?

 

No, it is something else we are working on. But the 5C did put TXCAMSS on the bumper, good guess.

You can always expect good 60fts from a Circle D converter, Great numbers!

 

Awesome 60ft man!!!

FWIW- The link in my sig has a video of us launching off the transbrake with the same converter. The front was tightened up for that very reason

It's a sweet converter no doubt.

 

Thanks TX yeah any of you guys are serious about a converter look NO further. These guys are the real deal in performance.

 

jfm, what's your car weigh? did you change the cam also to LG?

 

Nice times. I'm seriously considering a Circle-D converter

 

x2 i had my mind set on yanks SS3600 but now have began to change my mind on a custom built for circle-d. I don;t think you can go wrong after all the good responses lately.

 

Yep. I love my 5C.

 

I have a Yank SS3600 but if I ever have to replace it I will probably go with a circle D converter. Lots of good reviews on them lately.

 

nice 60 foot time. congrats.

 

Congrats. Gotta Love Circle D Converters.

 

my 5c should be here any day..Cant wait to get it in!!!

 

thats moving was that foot breaking or t/brake...i've heard good things about circle D i'll def be getting one for the 4l80 next season and trying there WOT lock up in my turbo car. has anyone ran there car locked?

 

If your referring to me it was off a footbrake. Here are some more vids from our rental.

This is the one where I really stood on the converter hard and it resulted in a set of soiled pants.

This is my PB pass a 10.14@130.9 did not give it the same converter stand as in the video above but still cracked off a 1.31 60'.

I am so beyond happy with this converter as I have stated in the past I would not replace it for anything.

 

I'm not surprised. I was just glad you didn't tear anything up. The torque converter is the single most important component of an efficient and effective set up.

Nice vids man!
