Hello everyone!
I'm in the planning stages of my next project as I need more money before I can start the build, but I have much to figure out so I'm looking for input.
The Car:
1928 Dodge Brothers Sedan (what I was told, but really don't know make/model/year)
I plan on making my own chassis, not 100% on size, thinking 2 x 4 x .120.
I will also Cage it, but want to maintain the use of the doors and easy of access, so it'll have swing out door bars (pending Bonneville tech, more on that later)
The rough idea:
4bt P-pumped, triple turbos, 47RH full manual VB, rearend and gears undecided.
I want to be able to drive it anywhere, so I'm not looking to chop the top more than 4-6", and I want some (i dont need much) creature comforts such as ipod w speakers and something like a Sparco racing seat with a tad bit of padding.
Remember this is mainly a street car, but I also want to take it up to bonneville and see what she'll do. The class looks like it'll be Classic Blown Fuel Altered in engine class E. or E/CBFALT and from what I can find the record is 208mph.
If I were to run the 6BT that would put me in the C engine class where the top speed in 246mph :bow: I'm willing to swap things like the rear end, injectors/turbos, and other small items to acheive my 200mph goal, but dont want to chop the roof to a 4" window just to gain a tad bit of aero. Although I will build a Bonneville nose to slap on that will help.
The only thing that is set in stone as of now is the car, as that is sitting in my garage now, but nothing else is.
Thanks for bearing with my A.D.D. ramblings, now the questions, or statements I need you guys to check and let me know if its feasible.
1) How feasible is it to push a P-pumped 4bt reliably at 600-700hp? This would be changing the turbos and injectors from the street 400-500hp setup to Kill setting at Bonneville.
2) If I had a different rear end just for my LSR would I still need a gear vendors or is the 47RH possibly up to the task of 200mph.
3) Will a built up 8.8" hold up behind a 600hp 4bt? They are cheap and plentiful, so I was considering going that route.
4) I did some very quick and basic calcs for airflow, and it seems for 700 I'll need around 80-100 lb/min of air (and obviously fuel to match) so I was thinking and S251 manifold turbo feeding two S256 which are rated at 55-60 lb/min from what I could find.
5) did more very basic calcs for Aero, and a 34 ford Roadster has a frontal area of 18.0 and a CD of 0.42. mine will be a little bigger and less sleek so I used 20 sqft and 0.46 CD, this nets a requirement of 617hp for 200mph, so I figure 600-700 is my goal. It also seems that those calcs are a tad overrated as I know people that have gone faster than suggested they should with less HP.
I will have a ton more questions and ideas, but I'm hoping to get some discussion started and see just how delusional I am :bang
