As some may have read, I am in the beginning stages of building a V4F/MR and have several technical questions. Please advise as you can.
If I want to make the body completely removable, how do I seal the top and sides of the front and rear firewalls to the body and ensure it is fireproof? I know how we do it in Helicopters at work, but I want to know what is SOP for the salt.
If I want to make the body completely removable, what is the "normal" method of attachment? A multitude of dzus fasteners, screws, bolts?
How is the engine compartment normally vented from pressurization at speed, in other words, vents in the fenders (if allowed), ducting, sealing off the radiator opening? I know the pressures can get pretty high and cause drag and, depending on the car, try to induce lift due to downward pressure exiting under the car.
This should probably go in the rearend section, but what is the most common type of rearend run. I don't mean hypoid, full floater or etc, I mean.... 7.5 inch out of a Vega, 8.2 Chevy, 8 inch Ford? I know that I will not run a 9 inch due to the extra power is sucks from the drivetrain. Personally, I am liking the 7.5 out of a Vega with a 2.29 gear, but I know of no one that makes C-Clip eliminators for it. I might have fab something myself. Keep in mind V4F or even V4 will not make huge power numbers.
Engine diapers? I have looked all over the rule book and can't find a requirement for them. I am NOT a greenie, but I also don't want to grenade an engine and cover the salt/track with an oil slick. What are others doing?
What is more common as far as manual transmissions. 1:1 final drive (T-10/T-4) or OD (T-5, TR-3550, T-56)?
I don't want any "secrets" divulged, this is a racing and a competition, but I don't want to beat my head treading where others have already been. I will have enough of my own head beating with some of my ideas.
