Engine/Transmission (1994 - 1998) #4 plate in a 215 pump

[12V Ford]

I was searching the forums and never did find a definate answer on this. What does a #4 plate make for power in a 215 pump. To make this equal, it has to be in the stock position and stock engine like on the tst charts. I remember seeing a chart that showed what the #8, 6, 5, and 4 plates produce in a 215 pump, but I can't find it. Does the #4 produce more power than the #10? I know the #4 doesn't defuel on top like the #10. This sounds kind of like a #100 plate.



Thanks,

If the pattern on the chart holds true, up the #4 plate, it'd be around 530hp. With the plates, as the # goes down, the rating goes up.



The power ratings on the plates is more of a guideline, in stock postion. Can be slid forward for more power.



Is the 6spd going to be able to handle the power level you are after?



The #10 and 370's ought to have you over 430hp alone.

Oh yea it's more than a #10 ... big time. It's similar to a #100 in that it's cut deep like a #100 & has a little ramp on it. The #100 is cut to the #0 depth with the ramp of a #10. So, it's a zero plate with a #10 ramp on the bottom.



The #4 in a 215 pump ... it's gross man. It'll make the drivetrain vibrate, the cab resonate, burn up a stock clutch & turbo. I ran a #4 in a 215 pump with #300 injectors & stock HX40-16. EGT is an issue. :--)



I've got a pic of a #4 along side a #0 in my pictures.

I hope the 6 sp holds up. I'll be finding out soon. I think it will. I was just on ATS's website and saw that they had upgraded zf 6 and nv 6 speeds for sale. I wonder how well those hold up?

It looks to me that the #4 goes in a little deeper than the #0 then comes back. Any dyno numbers for a #4 in a 215? Just curious, but how does the bottom ramp on the #4 work. I understand how the #10 works, it hits the ramp and then rides up it producing more fuel and then after it comes out of the deepest point, it cuts back on the fuel. On the #4, would the gov. arm hit the plate at the farthest point and then go towards the deepest point, or does it hit low, cuts back on fuel until it gets over the hump, and then fuels again on its way to the deepest point? Does this make sense? I don't want to be troubling, but I am trying to understand the bottom end of the #4.

I guess it depends on how the arm is adjusted. It might be that the arm hits the deepest point of the plate first.



When I swapped the #0 for the #100, I looked @ the face of the plate, where the arm has been "scrubbing" on it. It looks to hit the plate right at the deepest part of the #4. :-laf



Now on that early model 5 speed we put the flat plate in, I looked at his stock plate & the arm was hitting waaaay low on it, lots lower than mine.
