I've been looking at some different designs for intakes. I may be looking to design one myself for fun and testing purposes. Problem is I really don't have much knowledge on the subject except for what I've read in books and mags.

Now considering and LS1 here...
1. Is a large plenum really required here?
2. What about dual throttle bodies linked together with a long tube design which runs seperately to each bank? Similar to headers.
3. Doesn't the intercooler act as a plenum of sorts? Or is balance an issue?
4. Is heat soak an issue with a sheetmetal intake if it's insulated (coated)?
5. What would be the best design?

Said it had been tested back to back

I am using Accufab t/b with a conversion to a gm style sensors. I would give Hogan racing a call and talk over with them. They are really good about info.
