draw thru supercharged setup

[Anonymous]

I'm looking at supercharging my 250, but depending on what extras i need depends how quick it happens. I am mostly wondering about ignition and fuel supply.

If i do a draw thru setup, would 2 bone stock progressive 2bbls work without rejetting? I plan to put the induction tubes at the 2nd and 4th cylinder for more even fuel distribution. If the 2 stock progressive 2bbls work then i'm happy. I'm running into problems looking for fuel pumps and regulators, etc... i'm hoping for the most effective method on a budget, i really dont want to spend 300 bucks on a pump and regulator and another few hundred for timing retart modules and all these other goodies. I plan to run about 7 PSI boost on a stock engine. Its pretty fepressing looking at the prices of things i think i need to buy, but if i can get away with just having to buy the supercharger, carbs and the metal fabrication it would be fine. Basically i dont want to spend more than $250.00 on extra stuff aside from the supercharger. anyone have some ideas?

Oh yea...and does it matter if the SC is mounted sideways...that way i can install it lower down and it would be a bit easier to run pipes from the SC to the intake.

Like this? The picture is darn big. Left click, and save it to your computer. Then print it out.

Thats an awesome setup.

I was just told in a previos thread that a draw thru setup is dangerous...especially since a lot of my driving is in town. Anyone know whose setup that is? and the supercharger is upside down right? This looks like a setup i would attempt if it was/is safe from exploding, otherwise i'd have to adapt a 4bbl carb or 2 2bbls (i want to avoid 1bbls due to lack of aftermarket jets and floats n stuff) would a single progressive 2bbl be fine for about 7lbs max boost? or still not enough? dont want a gas guzzling 2bbl though.

thanks for the pic.

just by going off what i can see through the engine bay, i'd bet that it's a drag race only setup

ok..I think i have an idea now what i'm gonna do. Is there a good 4bbl carb i can use thats already setup for turbo/supercharged setups? and not crazy expensive either.

i think some of the early Grand Nationals used a 4-bbl draw through setup
they can usually be found on eBay

i know that a couple people here have snagged one

About the picture.

It is in about a '65 Comet that appears to be a drag race car. There are no inner fender wells - so it must have a Mustang II or straight axle up front. There are no sides to the radiator support.

It appears to be an Eaton M-90 blower like thos on a Super coupe 3.8. Yes it is "upside down. It appears to have a 4 barrell carb with a homemade low profile air cleaner and "cold air" adapter. The box to mount the carb bolts onto the rear of the blower in place of the MAF body.

It looks like it has a single V-belt belt on the wide pulley. The brackets appear to be angle iron. The tube to the manifold could be made at any exhaust shop.

I can't see enough of the engine to tell if it is a 200 or 250, but it has 5 "frostplugs". The head is a "flattop" log = so it is '69 or newer.

I pulled this picture from the archives of FordSix.com It was reported to be on a Comet racing somewhere in the South.

If anyone spots this Comet this summer, I for one, would like to see a bunch of detail pictues of the blower bracketry.

Thanks for the breakdown of the pic. Do they sell V-groove pulleys? or do u think he grabbed a double pulley off an alternator or something? that sure looks like a tight fit, I want to see if it can be located on the other side though as i have an alternator on that side....should be do-able as it looks quite small. anyone know if a stock alternator pulley would work on this supercharger? i wouldnt want to run more than 5-6 lbs of boost anyways for the street engine. That comet sure is a beauty.

The engine is a 200 becasue the starter is above the oil pan. Why is the supercharger upside down isnt that reversing the air being pumped out. Where would you run a intercooler on this setup?

shouldn't matter which way the SC is oriented, it's still pumping air through the same route
with that one you wouldn't install an IC because it could easily blow up

 

[Inline6Merc]

Why would it easyly blow up?
