Default roots blower on a c4

I posted this in forced induction/nitrous with no help. I know we cant run a blower that uses a gilmer belt drive due to clearance issues. So, that leaves us with running it directly off the serpintine belt. I know it would be simpler to use a centrifugul supercharger, but I really like the look of the bugcatcher sticking up out of the hood. What I'm confused about is the length of the nose drive needed to run one like this. Would something like this work?

Give DYERS BLOWERS A CALL>

My boss at work has a 355 ci SBC with a 6-71 Dyers Blower & Dual Quad Holleys.
It has been on the same engine stand for 20 years now.
Pulled all the spark plugs out & checked with my Snap On Boroscope.
No Rust, maybe 500 street miles on it is my estimation.
Perfect.

Guys around want me to install that Dyers equipped SBC into my 87 Vert.
My boss wants to sell it to me too.
Someday I just have to break down & hand over the $$.

Nothing stands out like a Roots Supercharger poking sky high through a Hood.
Bottom end & Mid range power on the street is incredible.
Making 800 + foot/lbs at the flywheel is easy.
Swap pulleys & Big End/ Top End power is easily had too.

The application guide advises

"Aftermarket pistons, connecting rods, and valves are recommended to assure engine durability. The higher power output will require an aftermarket high-volume fuel pump such as Edelbrock #1711 (130 gal/hr), 1721(110 gal/hr), 17000 (175 gal/hr), 1791 (120 gal/hr, electric), or 1792 (160 gal/hr, electric). The valve lash or lifter preload should be properly adjusted. If the valves are not properly seating, or the valve lash is not properly adjusted, the increased temperatures created by the increased power output could accelerate valve seat wear and cause burnt valves."

Not to mention you need a 4 barrel carburetor, a bugcatcher and a stealth device so that the police can't see you.

Lemme, thank you for that awesome picture. Brian, I was just getting some ideas together for an engine I would like to build for my car. You are right, there really is nothing cooler IMO than a blower coming out of the hood. I'm really thinking about saving the extra cash for a blower project like this. I like this because it can be done without any huge mods to the car unless you were doing a gilmer style belt drive. Like the one on that race car above. Oh how I would love to have the cash for that...

I am going to be building a new engine. When buying parts, I will be sure to take this into consideration in case I decide to do this.

May have to use a different pulley/bracket system but so what.

Theres nothing like a huffer (big middle finger lol) sticking out of a hood, who cares whats more efficient. They are badazz.


im pretty sure the C6 style (low w/intercooler) has been made for the Gen 1 might want to research it some.

Even an old B&M144 or a 177 would really really wake your car up.

Have a friend with a 70 Chevelle vert. It has a crappy built 383, horrible 882 heads and the wrong cam with a small 144 blower on it. Absolute pig NA but with the blower pulled so much harder than we thought it would all you can do is laugh.
With 4.11s a converter and a good tire on it definitely a contender on the street.
Pulled pretty darn well with 3.08s and a stock converter in it fwiw. Lotsa fun

That's what I want is something simple like that. No need for a huge twin carb blower that makes 16lbs of boost. There was a forum member on forced induction/nitrous that used one of those B&Ms.

I would question how much boost you could make before a serpentine belt would start to slip. Go big (gilmer) or go home. Also, I think the big belt is a major part of the badazz "look" on a roots-style blower.

I cannot agree more. Believe me, If I could find some way to fit a gilmer style belt drive in there I would. If you look at the harmonic balancer, there's only about 1/4" clearance to the rack and pinion. No room for the crank pulley there.

I assume the problem you are seeing is getting the belt drive to clear the front crossmember? I am new to these cars myself but was wondering if the front cross member can be notched and reinforced or even cut out and a new once built with tubing that would provide the necessary clearance.

Ok guys, a crazy motor needs something to put the power to the ground through. What about the rest of the car?

Gilmor Blower drive belts are the best.

Another friend had a DYERS BBC in a 16 foot drag boat.

He about died 1 Saturday afternoon on the Illinois River.
Flying around 130 mph & got airborn.

I had this Boss Harold back in 1999.

He had 2 Blown 484ci Keith BlacK Hemis.

One in a Drag Rail Car.
Another in a Speed Boat too.

He flipped them both around 200 mph.

The Rail car he skidded upside down for 1/2 the track on his helmet.

Harold was CRAZYYYYYYYYYY.
Beyond Bi- Polar.

He flipped the rail car & the boat both within 1 month.

He always was terrified of Blown Keith Black Hemis after the that year.
LOL

He switched to 572 ci BB Chrysler wedges.
Said it was safer..........................

If anyone tells you that Old School Roots Blowers will not perform & garbage.................
They really do not know what they are talking about.

For a 350 the 144 is just fine, 4-6 lbs of boost doesnt sound like much but will feel like you bolted on 100ci..cant really hear them til you get on it which is kind of fun. Sneaking up on someone then, once next to them hitting passing gear. that blower will scare the crap out of them. Lots of guys will talk crap because they wont make 11000 hp or are "less efficient than a Vortech". So what, since when is going fast/mpg a concern! If youre in youre in, go for it.
Fun stuff. They are pretty reliable

You are correct. My only plan for this car is to be one badazz street car with some occasional runs down the strip. I have no intentions (or enough funds) for a crazy motor. This is just some ideas I'm putting together, and that question just proved the fact that I haven't thought this through enough!
