[QUOTE="DemonSVT, post: 1793379, member: 435"] 1. The stock manifold is multilayer. Cast steel (much thicker then mere 16g) surrounded by ceramic packing and them SS clamshell overlays. The outer SS clamshell could be that 16g thickness you mentioned. Either way they retain heat exceptionally. 2. Wasting the exhaust flow with just one bank will cause that bank to have significantly less restriction then the other. That means under boost you will not be able to tune the banks equally. One will be very restricted by "powering" the turbine while the other just free flows out the wastegate! There is NO WAY around that. Also since the turbo is running off just the exhaust energy of one bank once the wastegate is open any extra exhaust gas the turbo can't use will try to back flow down the opposite up-pipe to get to the wastegate. This is where the reversion comes from. Again VERY bad for the turbine and efficiency of the setup. That placement of the wastegate is just terrible for many reasons. I just mentioned 2 of the greatest reasons. 3. Both the DSM and Conquest have additional airflow inlets above the lower fascia area just to feed the radiator. I know. I owned both. I have pictures if you don't believe me. Also the stock DSM IC was a small side mount IC. The StarQuest did have a large FMIC but you have to remember it was purposely installed at an angle and the opening in the lower fascia was HUGE. Larger then the FMIC. Plus both had the extra air inlets. So you are wrong in your statements on all those vehicles. If you want to post pics then it will only support my stance. Matter of fact you can go to my site and see pictures of a Conquest. 4. An idle test is plain worthless. Try that test under load! Especially when you are running boost!! (i.e. hotter IAT) Then get back to me. I've already done it on several cars including this platform. You seem to post like you are the only one that knows anything about turbo setups or this platform when in fact most of your shown designs and posted statements are bad or just plain wrong. Maybe you should just build this system and then come back with pictures and hard data. At that point you might be given a little more credence into anything you say. Posting you are going to do this and that can be done is not going to change anything. Actually doing it will. Go do it... [/QUOTE]
