Good luck on your build, hope it works out. Just food for thought. That budget ugly 62 Savoy 4 door has gone fairly quick with a nearly stock 360. 10.08@136 with a 3.23 gear in street trim at 3700lbs. Doug

Can anybody plot the range and trajectory of a carburetor after it goes thru the hood under a 10 PSI of boost backfire?  20 PSI?
What would the effect be steel vs 'glass hood, right vs left carb? 
Seriously, quickd100 has had some success blowing up a 318 with a draw thru running a single Thermoquad and making the numbers you are looking for and then some.

I found if you use the Mopar factory accelerator cable will keep it from going very far.
Doug
I forgot about the OEM carb tether system.
Does that pass NHRA tech or do you require an additional "approved" one?

I finaly agreed to go blow through and my Naysayers disappeared? I guess i'll give up my nightmare and just go single turbo single carb blow through financialy it will get on the road quicker.
A very good choice... with that set up you can/will
have help from people that have or are running the same
style package... plus you get a larger choice of turbos

Member 67 Satelite is going to sell me his Gt42, sounds like that will do the job, thanks!
Still waitin on my buddys to recommend a pump,regulator, and so on. Lol. I have -8 from the cell do i need that big as a return or can i go to -6 ?
Its always best to match the supply line or go larger
so you dont make too much pressure in the return...
just get a boost reference regulator... I have a Mallory
thats boost referenced on my NA set up already for
when I change over

Lol that thing is gonna be crazy, how much does it weigh?
Ok on the regulator, now i was looking at 140 gph pumps but what pressure will it need to be? Or Can i hook 2 holley blue's together to get 28 psi

It should in the 2800#-2900# range... no you cant
parallel 2 holleys to get 28#...when you do that you
gain flow.. not pressure... since your going to run
a carb you need flow but maintain the 7-71/2 psi..
if you go injected you need in the 50# range

for the pump u need 6 psi at idle and 1 psi for each pound of boost so 10 pounds of boost is a min 16 psi fuel pressure and a boost reference fuel pressure regulator with return min - 8an line
Gotcha Thanks!

On my turbo car, everytime I dropped compression the spool got better and it made more power everywhere.
I am in the process of dropping from 8.5 to 7.8.
It seems counterintuitive but on a boosted car the lower the CR the better.
I wonder how much of that perceived better spool was because the engine was already working so much harder just to run that it was already on the threshold of building boost?
Was that on a V8 engine?
I'd like to dig into this further when I have more time but I will add this:
I have had my own dynos for almost 10 years so I test every change I make to my car. The power curve started higher and earlier with nothing more than an comp change, it was 400 rpm earlier and 28 rwhp or so higher , same turbo, same tune, same boost controller.
The car was a rotary, but its still a 4 stroke motor. The comp change makes the total volume of the cylinder or chamber larger.
Dave Vizard wrote a lot about this in his books, and was the deciding factor for me to take the motor apart to go down to 8.5:1 from 9:1. I put his theories to the test and its proven itself. The interesting thing is the 8.5:1 rotors are actually heavier than the the 9:1 rotors, and the engine still made more power with the 8.5's.
When he says on the cover, speed secrets for any engine , he isn't kidding.
