Crankshaft centerline in relation to the pinion.
Less up pinion angle.

"The Bender"The crankshaft angle of the engine in relation to the frame rails. More up angle equals more hook, less up or even down angle equals less hook.

If the crankshaft centerline is 1.5 degrees up, the output shaft is down 1.5 degrees. Which would mean the pinion would be up .50 to .75 degrees, to arrive at or around 1.50 up degrees under power.
After the crank was moved 0 degrees, the output was 0 degrees also and the pinion down .50 to .75 degrees, to arrive at or around 0 degrees under power, at the hit correct?
Less up pinion angle allowed you to better tailor the driveshaft graph correct?

bry-warSolid dragster better be crank shaft aligned pinion. As in the face of rear housing parallel to the motor plate. Keeps em outta the cones.

I a word, no.
I am talking about a hardtail car here, so the pinion angle does not change under power. Didn't change the pinion angle, just the engine angle relative to the frame rails.

Believe it or not there is some wiggle room in the coupler between the engine/trans angle and the pinion.
We changed the engine angle 1.5° without moving the pinion/rearend. The two halves coupler still slid in and out smoothly after the change...……..I would not have believed this, but the guys at Elite said it would work, and they were right.

In that case the engine angle was reinvented parallel with the face of the rearend housing and motorplate. Same concept.

Hitler inspire you to learn that technique lefty?

Did they make two new engine plates, front and rear?
July 28, 2020, 08:29 AM
"The Bender"Just the rear, since the front of the engine was going lower they were able to use the front one over.....

MOPDRAGSTERThey are just like regular saddle except the "tab" that the motor plate bolts to is on a jack screw affair to raise and lower the "tab" to raise and lower the front of the motor to take bite away or add it.
Super popular on the comp eliminator hard tail dragsters.
Spitzer has built a bunch of them.
Hell we run our comp car -1.5 down in the front to try to take the wheel stands away

What about the midplate? Do you have to put spacers in it for the angle change? Are the mounts adjustable too?
