I have been doing some thinking and have a couple of questions, maybe you guys could help me.
The intake manifold should use some form of heat so the fuel is vaporized as it goes into the combustion chamber. If you dont use an intercooler in a blow-through setup, would the hot compressed air be enough to keep the fuel vaporized? (or would a suck through system be better to keep the fuel vaporized) If that works would it mean you wont need a source of heat for the intake or will you still need one?
Would the stock manifold be too restrictive for the flow of the exhaust gasses to the turbo? I'm thinking of custom making a header for the turbo but if it wont make much of a difference then i dont think it's worth spending the money. I was looking at pics of Dr. Santucci's turbo setup and his exhaust manifold looks pretty much like the stock one. There aren't that many bends or flexes and i dont see a collector either. How neccesary is it to have a collector. If I go for the headers, since im not gonna be revving this car too much,( Im not racing it) I guess short diameter tubes would be the way to go for the turbo headers or the other way around. WHat size pipes 2 or 2.5 inches?(they are goning to be short lenght not to lose much speed) Would a Holley 390 with vaccum secondaries get the job done as far as carburation goes?
Would the water injection setup i mentioned on this site help at all when using the turbo without the intercooler? Or would a better water injection system need to be used?
Please let me know what you think. Thanks.
