Several good sources of information here. If you ordered the Denmah kit then it comes with a wastegate. That is the part in the system that controls boost. Without it a gas V8 has enough BTU energy to spin a very large turbo really hard (POOF!). The turbo will not self regulate like they do on older diesel engines. I see the Missouri (misery??) license plate on the car, is that where you live? My parents live there and i wish i had access to E85 like they do. Build your fuel system to use it as it is very forgiving of tuning issues unlike pump gas, especially timing mistakes, ask me how i know....
I didn't order the full Denmah kit. Just the turbo, waste gate and BOV. Didn't have the funds to do the whole kit at once.
And please don't take this the wrong way, I'm not saying this to be an *ss in any way, but I'm very familiar with how forced induction works on engines and the components required to make them work. I actually have a Bachelor's Degree in Automotive Technology. Which really doesn't mean sh*t in this aspect but I at least know how most sh*t works haha. I've just never built a setup of my own. Again I hope you don't take that the wrong way, I just didn't want you thinking you have to explain how everything works to me, that's all lol
Man, I've thought about running E85 and I know that there are several benefits to running it in boosted applications (like the ones you mentioned). I'm just not sure I want to have to worry about the extra stuff required to run the stuff to start off with. Especially since I have a P01 ECM and want to run RTT, which keeps me from being able to run flex. Now after I have everything built and I've learned the ropes on tuning and such, I wouldn't be against adding everything for E85.
Yeah I know they are a little high but I'm going to do it to start with. I'll see how it does and reacts and change my ratio if it's undriveable.
