My car was the "prototype" car for Archie's V6 kit.

You don't need a Dakota Digital unit if you just use the 2000ppm output from the ECM (if you are using 7730) instead and change the divider to 7 or 8... You'll still need to convert the signal from digital to analog going to the speedometer...

Mines is 3.55 but first is 3.77 so it's as fast as the 4 speed 1st gear...if not faster...[This message has been edited by lou_dias (edited 11-01-2019).]

Since I have limited HP and TQ due to my displacement, number of cylinders and being NA, I designed the engine to
deliver the power as fast as possible, you can think of it as an antilag system on a Rally Turbo car.
The theory behind this is that becasue in the class I'm planning to run, the cars have twice the power but are much heavier.
So I can gain an advantage specially going into the corners, braking, coming out of the corners and accelerating.
Because of this sudden power delivery, the stock components are subjected to tremendous shocks and therefore the weakest links tend to show up.
So with that in mind the LSD should be OK. Now the weakest links are the axles.
If I use harder tires I can make the axles last but I don't want to compromise the grip of the softer tires.

Got it out. As you can see the axle wasn't all the way in due to the design of this particular LSD.
It incorporates a friction disc but is not hollow, which means the axle snap ring can't lock on its groove.
That is why you can see some twisting of the splines on the picture. I'll fix that.

I would prioritize fully engaged splines over LSD, but that's just me. ------------------

Ehh... It had enough spline engagement to wring off the shaft... what more do you need?

Tell 'em Will! 
But yes, I'm addressing that now. Got to have it fixed before going any further.

Finally I took it her out for the first time on E85 and stiffer suspension!
I have to do lots of tuning yet so hopefully I can get on the dyno this coming weekend.
Springs are the way I like them, I can now feel the road!
I drove it for about 45mins and this short video was taken right before going to my house.

I had to lower my plug gap with E85. Looking forward to that dyno!
