i know this has been asked a bunch but here it goes again. ive got high egt issues and do not want a large laggy turbo with my auto. if i bought an ats and had it ported would it help with egts? if i could get the egts to climb a little slower, i could do runs on the dyno without hitting 1700. i hit redline and 1700 at the same time. redline and 1500 would make me feel alot better.

thanks all, mooseman

 

Don't expect much egt reduction from a ported ATS, 50° max.
Main reason for using an ATS is to prevent the very common warping and cracking that goes with the stock manifold.

 

What about the quicker spool ats claims? Is anybody really noticeing this?
It would probably be a good idea to get an ats now because of the heat im getting. Its got to be expanding and contracting alot more with the extra heat.

You can get the ported ats, port the head and a bigger cam. They all reduce egts.
A high flow filter set-up helps as well if you dont already have one.

 

With the ported ATS, Scotty II, and straight pipe on the stock exhaust system, mine has never reached 1200. Larger injectors would heat it up as will the comp, but the combination does work to lower EGT's

 

Hey moose, we've seen the best drop in EGT's porting the manifold and also having it HPC coated. The only things that are going to drop your temps down significantly are going to a larger exhaust housing, 16nonWG on your hybrid will help a little bit, or going to a true HX40 w/ 16WG. But even with the different exhaust housings you will see high temps. The best solution is going to be going to a switzer type turbo (B1, HTB2, Aurora, and others), or twins. The manifold wont hurt, but you wont see any huge differences. For a couple quick dyno runs 1600-1700 isn't going to do major damage.

 

kdawg, can you guys down there do the porting or do you send them out. I am already running a 16 nonWG. Twins are coming but not for a while. I just want to whoop with minor mods for now. Its to fun shutting down the ricers,corvettes,gassers,etc on the new dyno. I dont want to quit while i wait for twins.

basically you just port out the outlet on the manifold and then port the exhaust housing on the turbo to match it. Then get a gasket that doesnt' have the divider in it. I could find the part number for it if you want. I've just done it on a few buddy's trucks. I'll PM you about it

 

my old setup i had hp high flow injectors and the hot program edge comp cold air intake 4inch striaght pipe couldn't get it over 1300 every
