Engine/Transmission (1994 - 1998) tst fuel plates...

[shorty2500]

I am going to try the #10 and see what takes place...

howard,



looking at your signature, i see that you have a '94. unless i am mistaken, the #10 is not recommended for your truck. check the tst website for plates specific for your truck.

if so, is it possible to run a #10 plate, in a lower pedal position and not get the clutch-destroying torque and the heavy smoke?

Shorty, yes, it is possible to run a #10 plate and not have it destroy a clutch. You will just be setting it at the same position as the stock plate or move it back to give it even less fueling at certain RPMs. The more you move it forward from stock allows that governor lever to move more forward thus fueling the engine more and giving you more power and torque. Did that answer your question?

Why does TST not recommend a #10 for a '94 engine? I know lots of guys running 10s in the '94s with no issues. What gives TST?

The # 10 in stock location with the stock govenor set up will give less fueling than the recomended # 6 at rpm.

shorty2500,



I checked the TST site and you are correct, they do not recommend the #10. In fact the only ones they do recommend for the 94 are the #6 and possibly the #5 after transmission upgrade.

I would imagine that after some other modifications have been made, these recommendations may be more flexible.



I installed the #10 yesterday and haven't had a chance to drive it yet. If it turns out to be unsatisfactory, I may put the Banks plate back in or try the #5 again.

With the #5, I was spending a lot of time watching the egt gauge but liked it otherwise.

If I understand the function of the plate correctly, with the #10 profile, it starts fueling right away and then begins to defuel as you approach full throttle.

I adjusted the governor lever down to touch just above the lower tip of the plate which is a considerable change from it's position on the #5.



A warning to anyone who intends to adjust the governor lever. You CAN drop things inside the governor housing including the adjusting screw itself.

fuel mileage

What for fuel mileage does everyone get with the plates

... let's say that the pedal has 10 positions...

- position 1 = idle

-

- position 5 = 1/2 power

-

- position 10 = at the floor (max power)



for a stock plate in the stock position, let's say that pedal position 5 = 400 ft-lb torque. for the same pedal position 5, would a #12 plate have 500 ft-lb torque? would #11 have 560? would #10 have 620?



if so, is it possible to run a #10 plate, in a lower pedal position and not get the clutch-destroying torque and the heavy smoke?

It is possible to run a #10 plate in about any position and not get the clutch-destroying torque and smoke. The controlling factor is your foot. The plate works in conjunction with the governor, the throttle position, and the current RPM to determine the fueling needed at each moment. The power output at a given throttle setting is not the same at all times due to the other variables.



So if you drive as if you have an egg between your foot and the throttle pedal, you can run with the plate and not kill your clutch. But that takes a lot of dicipline! Press a little too hard to make that pass on a 2-lane, or make that light on a yellow, and WHAM! You have all kinds of torque and smoke... and possibly a fried clutch.

Mileage I have got as bad a 13. 5 all because of me as I just put the Bombs in so I had to play lots lol!!



Last tank I got 16. 6 that was 150 miles towing a 3000lb boat and 30% 50-75, and the rest around town often times racing people. I just have to much trouble keeping my foot out of it

I have a #5 slid all the way forward in my 94 5 speed. When I bought my truck, it had a new stock clutch just put in. I've abused it for about 10K miles. It does not slip in any non abusive driving situation. I can tow 10K in 5th gear floored and it will never slip a bit.



There is one way I can get it to slip, though. If I am drag racing in 4x4, a hard shift into 4th or 5th will slip it if I'm on it before it's engaged. All I do to keep it from slipping is let it grab before I get on it, and it's fine.
