I know. These guys are from Serbia and they have very good reputation with the European crowd. Their design is so much better than Phantom Grip, no shavings on your trans.
I don't want to keep breaking axles and trannys.

Just to give some updates!

Got the material to make a flat bottom to increase down force with less drag.


I know! "Are you still with a distributor?" I get that question asked a lot.
This Pertronix box gives you multiple sparks all the way to redline. Unlike the MSD's that will give you multiple spark until 3000rpms! Throttle response is awesome!!
This weekend I'm going to Florida for vacation and to pick up my trans. I'll meet Fiero enthusiast and friend Blacktree to do some work on the newly acquiered trans. Then is a matter to install it in the car. Can't wait! Should be hitting the Dyno soon!!

Did you have any misfires with the HEI module?

What do you mean? I had misfires only when playing with the spark plug gap. Once I set the right gap it revs clean and crispy.

Just out of curiosity, what is your spark plug gap?

I'm currently using 0.045" gap, which is the spec for the 3.4 V6 in the F-Body. Anything larger causes misfires and sooty spark plugs. Haven't tried smaller yet.

I've been running .050 with the small MSD anything bigger than that and it misfires at high RPMS After I installed this Pertronix box I haven't play with the gap.

You need to remove the trans mounts and need a way to hold up the engine. I've used an 8" piece of 2 x 4 between the starter and the cradle to do this. Maybe not an ideal way but it works. This is the way Ed Parks at the Fiero Factory did it.

Yeah with a better/stonger ignition you can increase the gap, that's why DIS on a 3.4 used a .060 gap but distributors call for .045 ... however when you increase compression ratio, you have to decrease the gap slightly to compensate. For instance, my DIS 3.4 has about 10:1 CR and I run ~ .053 gap.

Umm... Hmm...

That's just really just a peg-leg burnout preventer.
