Track times with Circle D converter

[1Bad5.0]

Well i made it to the track this weekend with the new Circle D 4 C converter....unforunately it was 1/8 mile racing, but i did get a good idea what it can do now. Before the converter best 1/8 mile time was 7.77@92 with a 1.84 60'.......after converter it was a 7.48@92 with a 1.67 60'....so three tenths quicker to the 1/8......The converter was just locking up at the finish line so i think 1/4 mile times will be even better.

How did you launch, were you stalling it up or just stabbing from an idle? Nice times!

Congrats! These autos are awesome.

good job!

I'll be looking forward to 1/4 times when you can get them in.

nice gains , but I would not expect to pick up any more on the back half. The converter really only works for you in the 60' and with your mph being the same before and after there is no reason to expect the car to pick anything up after the 1/8th. Regardless 11.5-11.6 is very nice...what all is done to the car?

I was leaving just slighlty above idle....just enough to take the travel out of the suspension.

Boss IM, Lethal ORX, C&L CAI, Circle D 4 C, and Drag radials....No weight reductions

Why didn't you stall it all the way to where it wanted to push threw

 

[turbosha]

leave off idle next time. you will get weight transfer and flash the converter.
will hit pretty hard.
idle: foot off brake:floor it!!!

you need to experiment with the converter to see what the car wants. Try leaving off idle and stalling it up to about 3000 and let it flash the last 5-700.

That's good. 1.6 60' times are where I am without n2o. Try different techniques mine liked different launches 275/60/15 vs. 265/40/18's.

Next time out i definitely plan on trying different things. I had talked with Chris from Circle D and he said most guys were having better luck with just slightly loading the suspension.....I didn't try many things other than that because i was into the money rounds of a bracket race and was trying to keep that consistency...On test and tune night i'll try many things.
