Pyrometer Question
I am installing my pyro. I am going with pre turbo. How many have put it in the "Y", right before the turbo, so you get both sides? I know some puts them in the lower pipe. I would like to measure both sides I believe.
Thanks

Good call, CSI, that was going to be my answer.
By the way, when I get my new exhaust housing (1.0 w/w.gate) I will be taking out the divider in the "y" and machining as much out of the housing as I can get to before I slam the turbo back on.

Dont remove it! Its there for a reason. But if you want to shape it some and blend it I cant see where that will hurt. But if it was me, I would get a new one from Ford. 90% you will break the bolts off trying to get it out, and then you need to replace the dougnuts while your there.

I didn't know there was a divider in it. It seems that the gases would be flowing too fast to see much of a temp drop before the turbo, don't know. I may just go ahead and put it in the up pipe. It probably would be easier than climbing around under the hood.

Just drill and tap the manifold, that way if you ever remove it you can just cap it... I have a drill and clamp on in the up pipe and now with the new gauges I have to weld up the hole this weekend... Because the new ones were drill and tap.

CSI,
Mine used to have the drill and clamp style....just drill out the hole bigger and tap it!! The clamp ones are usually only a 1/4" hole...a 1/8 pipe tap requires 5/16"

Cleatus I would be very interested in hearing your findings on that test drive. I know that the flutes are there for a reason to make the turbo more efficient.
But if removing the barrier gets rid of a lot of exhaust flutter and gives a little more lag in return, that might be a fair tradeoff IMO. As long as it doesn't ruin the boost numbers altogether.

But I still would be interested in what the differences are.
The same volume of exhaust gas still has to go out through the turbo.
And I am sure that putting in a passage would increase turbo response time. (more lag.)
But if it lowers EGT's significantly without sacrificing power while pulling a large load up a big hill, then it's a worthwhile modification for me. I'll trade an extra second of turbo response for that.
