Howdy all.
This is my first post to ya'lls forum and I figured It wouldnt be a bad idea to jump in on something that I know. IVe been running a turbo Volvo 740 for the past few years and have managed a 14.2@96.2mph on an old 8v OHC 2.3-4cylinder turbo. The few things that jump out with me are these:
1: Placement of the Turbo. The feed to the turbo would need to be somwhere off of the Y-pipe of the exhaust. Granted You could feed it off of the front bank, but you will run into exhaust flow problems due to a few reasons:1. a SERIOUS flow restriction that will vary with Trubo speed and wastegate setting and size, on one side of your bank of cylinders, and also the flow on that single bank will not be a vary consistent means to pump the exhaust turbine of the Turbo itself. 2: The previous problem will lead to this.. yeas you can put it in the area where the battery is located, but your equal length exhaust feeds to this locatin would be unreal, or if you feed it off of the y-pipe you are adding MAJOR exhaust flow restrictions, which are optimal in getting peak performance out of a turbo.
Ok 2nd thing that jumps up: Turbo sizing. Hmmmm if you goto one of my old Volvo Sites
www.badbricks.com and goto the How to size a turbo link. Its kinda crude but it will give you the basics for figuring out what size turbo you need for your car. To get your Engines ER , goto Ray Hall's turbocharging site, he has a few good calculators based on fuel load , etc, that will allow you to get a good read on your engines ER rating for the flow of the turbo. The problem i see with the flow sizing of this turbo is how do you want to run it, street or strip? and f its strip,then finding a turbo that would be usable in the uper powerranges will cause UNDUE lag in the lower end of the RPM ranges. If its street the exhast opposite problem is there.. you will die off on the turbo as it reaches the upper ranges of its flow limits and then you will notice a drop in pressure of flow to the engine(ie undersizing a turbo). (jsut a side not, i honestly thing a roots/eaton style whipple charger would be the best for our C-Tours..but.. thats an impossiblity, financially and otherwise).
Ok 3rdly. Hmmmmm How do you purpose to handle the fueling requirements of the Turbo?I wont even go into the complex problems involved with that.
And 4th. How do you plan to intercool this charged air to keep detonation down in a car that has a VERY high compression ratio? Alky injection would seem to be the easiest..and if not alky then, intercoolers would be required and then managing to install while maintaining suitable intake ducting as to not impose further intake restriction would be high near impossible. Okies. Sorry on that note I think I'll shush up.
so good luck and Once again.. Hi! Its good to be a part of the list!(I hope my signature is a good one.... I dont even remember what it is..LOL... oh yeah and I can't spell or type for dookie)
