1967 Dodge A-100 Hot rod sort of rat rod build thread.

It is now shifting nicely through all four gears. Although we have to adjust the shift linkage. Right now if you banged forward on the shifter it will still go into reverse. Need to adjust so that lock out is working.
 
With the potentiometer turned all the way up it is not giving enough assist. Hard for me to believe this unit can't turn those wheels like butter. But I have two 90 degree vdog boxes and a rack that turns faster than normal. With all of that and 10" of sticky rubber on the ground it may not be enough. Going to call EPAS in the morning and I may need one of these. https://epasperformance.com/collections/racing-applications/products/60-amp-custom-race

Our race unit is always on, and simply idles when traveling in a straight line. The unit has a torque sensor and provides the exact amount of assistance as needed, based on steering input from the driver. It offers little to no assistance at higher speeds, as none is needed. It is NOT "twitchy", if that is your concern. We would not be the industry leader and could not sell them otherwise.

No Bueno on the race EPAS unit. It has the same torque with more cooling for extended loads. I will have to live with it. Maybe bump the front tire pressure. The quick ratio of the rack combined with that wide of a front tire is the issue. Need to drive the truck and see how it does on the road. If I can't live with it I would need to redesign and build with a hydraulic rack.
 
4,650 RPM it's making 600 ft lb of torque at 3 lb of boost. Spinning the tires on the dyno. Dropping from 34 to 20 lb in the rear tires and going to spray some sticky stuff on the rollers try to get it to hook. This motor and combo is wanting a lot of fuel.

Holy crap. 5,100 RPM and 4 lb of boost. Spinning the tires on the dyno and torque numbers high enough to break parts already. Pulling the 8 lb spring out of the wastegate and putting the 3 pounder in and then go from there. Crazy. And yes we recalibrated the dyno just to be sure.

Love the fact that you're posting torque, and not HP numbers. 👏

Coming along very nicely!

P.S. I can't turn the steering wheel on my F350, without it moving either.

No big. 😜
 
We are having a hard time keeping this thing on the rollers. Ended up calling a time out and calling RPM on this transmission. He said 700 lb of torque Max and I am exceeding that by a good hundred pounds. Decided to call it and just pull this thing off the dyno. Afrs are all good now. Ended up with a 7 lb spring in it and we won't even use the boost controller. Set the rev limiter at 5950 because this stroker is such a torque monster. Little bit of work to do next week and might make good guys next friday. It will be close.
