The problem with POST TURBO pyros is the inconsistancy with mounting locations. Because of this, one post turbo probe does not always match another post turbo probes readings and cannot be shared with others.
PRE-TURBO pyros are mounted in one of two locations, In the UP PIPE about 1 inch from the coupling to the manifold, or in the manifold itself about one inche from the coupling. Because of this consistant location among ALL pre-turbo probes, we can share the numbers and be consistant.
Garret (the guys who build our turbos) say 1250 degrees PRE TURBO TEMP is the absolute redline for long life. They say our turbos can run at 1200 degrees pre turbo until the end of time.
Smokey_Wren on the other site had both pre AND post turbo probes and said he could hit 1200 pre, but only 800 post. Other days he could hit 1200 pre and 1200 post at the same time. He said it was too difficult to predict and has just gone with the turbo designer's recomendations of PRE TURBO, 1250 redline.
I would have to agree.
PRE PRE PRE!!!!
