kingbrad yes truck is an automatic with a Suncoast triple disk TC with a 1400 RPM stall. and it already smokes like a locomotive when i take off from a stop so like you said i should be alright with spool up. and yeah my egts are threw the roof right now so i kinda had to start pushin more air and what better way than with compounds!

Well your automatic may be different but mine is more responsive now. And it was kinda a PITA for the bracket deal. Also if your planning on running drive pressure, take that into effect when assembling these things. I'm in that boat as an afterthought now . Both of the bottom plugs in the manifold are more or less hidden by the 475 and I really don't feel like disassembling it or drilling a manifold that already has 3 ports!!

Yeah when I did my compounds I flipped my manifold that was egt tapped on the top side. Didn't want to drill another hole so my egt probe is on the underside of the manifold. I couldn't get to it if I wanted to!

I hear ya. There is no way in hell anything is going in the 1/16 NPT hole. I can see the 1/8" NPT one but it is about 3/8" away from the 475 housing and just in front of it. I was debating making my own adapter but IDK yet.

Sounds like Swiss cheese

KXTRAP now when you say running drive pressure exactly what are you reffering too. Cause I have a boost gauge and im getting my boost reading from a tap in my intake manifold. Also the pyrometer is their a place to install thats easily accessible or is it more like a renco oven where you set it and forget it cause you'll never see it again. Also I have a bladerunner afe manifold could I use this manifold or be better off to use to one supplied with the kit

Drive pressure is what is driving the turbo(s). It's measured in psi at the exhaust manifold. The ideal drive pressure to boost ratio is 1:1. I was told when running compounds that having a DP gauge is a good idea. Your talin a bladerunner exhaust manifold right? (just to make sure, they have the same name for their intake) It doesn't matter. DPS seems to be more on the economy side. Your AFE probably will work just flip it.

Yeah it's basically running a boost gauge off of your exhaust manifold. It should read very close to your boost pressure. There are theories that when drive pressure is higher than the boost, that blown head gaskets result. If you do a drive pressure gauge make sure you use a few feet of metal line coiled up before the nylon line, just so the nylon line doesn't melt from the exhaust and manifold heat. You can buy drive pressure gauge kits that come with everything you need

Autometer sells a copper coil kit for this. I got mine from Aligator, i believe it was something like $16 or something like that.
