I'm gathering information to aid in the bombing of my truck, and trying to<br>get a list together of the parts I will need, and how they work together.<br>Next on the list is a #4 or #5 plate from TST, 3K GSK, and AFC spring<br>kit. I am also considering the turbo-master.<br><br>My question is this: Does the turbo-master take the place of the AFC<br>spring kit? It seems like the spring kit changes the responsiveness of the<br>wastegate, and with the turbo-master, you set it and forget it. Which<br>would be best to use with future upgrades, hopefully to be 191s, 370s, and<br>I'm sure a clutch will be needed in there somewhere?

 

Mechanic,<br>The Turbo-Master does not take the place of the AFC. The T-M functions seperately from the AFC by limiting boost pressure to a predetermined level. The AFC accepts a boost pressure signal to alter fuel delivery according to pressure change. The two do seperate but equally important jobs.<br>Hope this helps<br>Dad

 

Thanks, dad. Let me see if I've got this straight. To make power, you've<br>got to burn fuel. The more fuel you burn, the higher your boost pressure<br>would be, without the wastegate, and the higher your egt's. To lower egt,<br>you want more boost for a given fuel burn rate, therefore, the turbo-master<br>will let you go to the maximum safe level of boost. This feeds back to the<br>pump, telling it there is more boost, so it can provide more fuel up to the<br>limit imposed by the plate, and to a lesser degree (maybe) the delivery<br>valves and injectors. Is it really that simple?<br><br>mechanic
