Bad Ass Blower

Hey, welcome to the horsepower shop. Now, I know what you gotta be wondering right now.

That thing got a hemi

in it.

You bet it does. In fact, this 68 Dodge Dart belongs to Wayne Tunis

in.

It's an authentic replica of the factory hemi

cars that were built back in the late sixties to battle in the superstock wars. Now, the centerpiece is this 700 horse race

hemi. Yeah, Wayne's even carried the factory race car theme inside as well with these lightweight seats. He Pirated from a base model van.

This darts such a stripper, the factory replaced the window cranks with these pull up straps. Now with a lightweight body and a hemi

under the hood. No wonder cars like this killed the competition on the quarter mile.

But you know, finding a hammy today is not gonna be easy and if you do well, it's gonna be expensive. I guarantee it. Now, a reasonable alternative is an RB engine.

After all, they're still fairly plentiful,

they're durable and they make pretty decent power with affordable parts.

Now, this 69 road runner has a 500 cubic inch indie cylinder head crate engine

and with a flat tap at cam, an 8.5 to 1 compression.

This is the perfect platform for today's blower bolt on

who needs a hemi

when you got a big monster like this sticking up through your hood,

it's an 871 root style super charger from the blower shop. It features a new case billet in plates and since it is a street blower,

they hall

to analyze the rotors at a teflon ceiling strip and they set it up with more case clearance for reliability. Now, we got ours with this optional show Polish, which is money well spent if you're planning on showing off a big huffer like that one.

Well, let me show you the intake that we're gonna use to make that blower to our RB engine. Now, this one comes from Indy cylinder head as part of their blower package and it features huge ports here that'll match the max wedge openings and most ported ports in after market heads. Now, the rest of the kit includes drive pulleys and belts,

the car plate, fuel lines and car blankets. Now, the choice of carburetors though is still left up to you

before we vote anything on this road runner though. Let's get a baseline on our

dyno Jet.

Wow, 436 horsepower. That's pretty healthy for a pump gas street motor. And you got that right. What do you say we get this thing off the rollers now so that we can go ahead and start on that blower. All right.

You know, one of the really cool things about a Mopar

is that they're so easy to work on. In fact, to remove this intake manifold, we don't have to drain the coolant or pop that distributor.

Now, once I get this battery disconnected,

well, here's all we have to do to make way for that blower.

We'll start by removing the fuel line

and capping it off.

Then the ground strap to the intake.

After removing the throttle bracket and return springs, you can disconnect the linkage.

Next, remove the eight intake manifold bolts

and finally, you can remove the intake and the carburetor as an assembly.

It was pretty easy, at least for you. Now check this out, we didn't even have to replace the intake gaskets because they stayed in place and well, yours will too if you glue them to the heads instead of the intake. Well, now we can drop this blower manifold in place and set it down with bolts from the kit

and once their finger tight torque them to 25 ft pounds.

Now, before we mount the blower, we're gonna install this crank shaft and blower drive pulley since we've got the room. Now, the crank shaft pulley goes on first and this big retaining bolt gets torque to 100 and 25 ft pounds.

Well, we're just about ready to drop this blower in place. But first we need to fill this front gear case with some gear lube and to make this job easier,

I'm gonna loosen this idler bracket. Move it out of the way

that gives us better access to this plug.

And a lu you use needs to be an 80 W 90 GL five or a synthetic equivalent or like this royal purple max gear.

Oh, by the way

before you reinstall that plug, make sure you put some Teflon tape on it

to prevent any leaks.

Well, that's a great tip on that plug. And while we're at it here a couple more from our sponsors. Now, don't you go away? Because we're gonna be back with more of our mo

blower build up right after this.

The Saturday night cruise is a high performance tradition that goes way back. We'll take you to one in America's Heartland that's jumping with eye popping rides

and an earful of incredible.

You guess it horsepower. It's all later in the show.

All right, here we go.

He,

I

think I just hurt my hemi

Roids.

Hey, we're back with our blower project here on this 69 road runner. And as you can see, we just dropped our 871 super charger from the blower shop into place. Now, what makes this whole deal possible is a blower kit from in the cylinder head that includes this intake manifold that we installed earlier,

the studs that attach the blower to the intake are aluminum. So you wanna give them a dab of anti C to keep them from galling up and make sure that you don't over to torque the nuts.

Now, it is also a great time to install the lower throttle bracket which mounts up using these two center studs.

Here's a little heads up for you only torque those nuts 10 to 12 ft pounds. And once you're done, well, give that thing a quick spin or two to make sure everything's rotating freely. Hey, we're looking good here. All right. Well, let's install this blower belt. Let me

give you

a hand

that

now we can set the belt tension with the idler pulley, which does double duty by also keeping the belt centered up on the drive pulleys. Now, this tension setting is very critical. Too much could cause the belt to fray

and put an extra strain on the crank snout

with the engine cold. You set it so that you've got three quarters to one that you play.

Once everything's up to operating temperature, this will compensate for any heat related dimensional changes. The play of the belt will only change to about a quarter inch.

Next, we can bolt up the car plate. Now, it uses the screen gasket that goes in between the plate and the blower. Now, not only will it give us a good seal, but it'll prevent any loose hardware or unwanted debris from going into the blower. Now, even something as small as a throttle blade screw could damage it if it works itself loose.

I gotta tell you that thing looks a

impressive already. So now I guess we're ready for our carburetors.

We're going with a pair of these Hollies that are set up for blower applications pretty much out of the box and to make them work, Holly installs these larger boosters that deliver huge amounts of fuel on demand. Now, the body is an HP design with a milled air horn,

contoured venturia and adjustable air bleeds. Now, these are double pumpers and each one's rated at 750 CFM.

Now you wanna make sure to use new car base gaskets

and install the carburetor sideways on top of the blower.

Now, the reason they're mounted like this is to keep fuel from sloshing away from the jets during hard acceleration

and starving the motor for fuel. Now, we're only gonna use six bolts to hold them in place for now.

Hey, great job on those carbs there guys. Now, here's why we left those two bolts out. The upper part of the throttle linkage just mounts up right here. Let me give you a hand here. I appreciate that.

There we go. Now, once we get these two bolts started here, we can go ahead and tighten up the rest of them.

I just finished adjusting the linkage right up here next to the carb so I could check to make sure that we've got wide open throttle.

There we go. Then I went ahead and installed this intermediate shaft on the throttle linkage so I could check the entire system for binding.

Hey, we're looking pretty good.

Hey, I'm glad to hear that. Now, guess what? We're gonna wind up this blower installation and lay down some new horsepower numbers on the

dyno Jet. When we come back. Stay with us.

We're getting mighty close to firing up. This supercharged 69 road runner

here man, have a couple.

But before we can make any noise or numbers on the dyno Jet, we gotta finish plumbing the fuel system. Now,

during the break, I preassembled most of these fuel lines. First step is to finish installing these A N adapters on the fuel bowls,

then connect the fuel lines to the A N adapters

and the main feed line

to the distribution block.

If you're running an electric fuel pump and you really should be with all the fuel a motor like this is gonna need. Well, now is a great time to pressurize this system

and check it for leaks. Go ahead and hit the key, Joe.

Well, good news, no leaks. Now we can fire this monster up, set the timing at a safe 28 degrees. Then see how much more power we've got on the dyno Jet.

Now remember our baseline was 436 horsepower at the rear wheels.

Man. Looks like 711 horsepower at the rear rollers. Now, that's pretty impressive.

Now, that's a jump of 275 over the baseline. Let's see if we can get a little more timing in the motor and get a little more power. You know what? I think that's a real good idea. In fact, let's bump this thing to about 32 degrees. Go ahead and crank it. Joe.

Well, how'd we do? Oh, man, looks like we lost a few horses on that one. We're sitting at about 700 now. Well, you know, that's not really surprising. So I guess we'll go ahead and back our timing down to 28 degrees again. But, you know, here's a rule of thumb that seems to work pretty well for all blown engines. Whether you have a turbo, a centrifugal or a roots type blower like we have here

now for every 100 horsepower that you add over normally aspirated, you wanna go ahead and back your timing down about two degrees. For instance, if you add 200 horsepower, you need to crank about four degrees out of that thing. Now, you can do it right here at the distributor like we did or if you have one of those new fangled ignition boxes, you just might want to check it out, just might have a boost retard built in it.

Good point when you're running pump gas, the last thing you want is detonation, but here's something you do want on the street and that's an air filtration system

to keep the crap out of your motor. Here you go.

Now, if you wanna make a strong visual statement. Well, how about bolting up a scoop like this? That comes with a pair of air filters? We got this one from Wyatt.

Well, that big blow over there is pretty awesome, but you can also get a mini blower like this. That's just as easy to install. Adds a lot of eye candy under the hood and it'll give you a pretty good boot in the butt. Now, depending on the pulley size you go with this thing will make 5 to 8 pounds of boost for a lot less cash.

You know, that still sounds like a lot of bang for the buck to me. Now, this big blower set up that we bolted on today is gonna set you back about 3300 bucks that includes everything except the carbs and the scoop.

As you saw this Mopar installation is really simple. In fact, I believe you could finish one up in probably 3 to 4 hours. Yeah,

if you got a Ford or even a Chevy, it'll take a little bit longer. But basically it's just a manifold swap with a couple of pulleys. Say, man, you like to go to cruises, don't you? Oh,

hey, the food is great, but I always get seasick. I'm talking about car cruises, Dipstick. We're gonna take you to one of the coolest we ever found up in the Heartland of Kentucky. When we come back,

you can't get more small town, mid America than Somerset Kentucky here. A quiet little town except one Saturday every month. That's when they celebrate a tradition that's

as old as the hot rod itself. And

the invasion is about to begin

from street rides and classics to muscle cars. They arrive early for a prime downtown spot at the monthly summer nights cruise. How y'all doing today?

We've had cars from, as far as the way as Ontario Canada.

Uh, we have them from usually from about 11 to 12 states at

every show.

Uh It's,

it's just remarkable,

especially since there are no trophies. No best of show. Just the joy of showing off your revered ride to the Spectators who fill the streets.

We have nearly 250 to 300 new participants each month.

Our average right now is about 1000 cars a month,

uh per show and, uh, it just keeps growing, it just keeps getting better.

And,

you know, we, we have a lot of fun. That's what it's all about. And of course, with all these

enthusiasts with hot rodders, you don't hear any

sounds of burnouts later on, do you?

Uh, well, I prefer not to comment on that because, uh, there are some actual members of local law enforcement on our cruise team,

the variety of cruise rides is amazing. Like this 80 Monte Carlo low rider that doesn't quite seem to match

its owner as they say, how low can you go?

So, that's about two inches off the ground.

It'll go up, it'll go up probably to 1415, 16.

It catches a lot of eyes and

because it's different, it's one of a kind,

the owner of this flame throwing 47 Buick likes to stand out from the crowd as well.

Something different.

I wanted to be able to pull into a show and go. It's the only one here.

Yeah, because I've had probably six different show cars and

Vegas Camaros. 56 Chevy with a blower. Yeah, but I wanted something completely different this time.

You can always find a heaping handful of horsepower at summer nights.

How about this front engine dragster transformed into a drivable street ride.

This was an old original drag car in Chicago in the sixties.

But I figure it's got almost 300 horsepower, something like that.

And uh,

I think you're a conservative a little

bit just to

uh 604604,

4.5 inch, 44 and three quarter inch stroke. Really? How much horsepower you think you're making?

Well before I put the blower and before I put the knife,

it was 872 or 7000

and I don't get to get attention to this

thing.

Do

not at all.

It's just a regular chick. Magnet. That's, uh,

what do you believe that? Yeah, they run from it,

from it. I promise you, they run from it. That's how it was supposed to have them.

And thank you for being with us today. Here's the T shirts for you and your crew.

Well, after an eye full of cars and a handful of free t-shirts, our summer night's afternoon is just about over.

And so the sun sets on another summer night's cruise here in Kentucky with a near record of 1050 cars.

Now, the finale is a cruise down one of the main drags with the roar of the engines and

this may be a little tire snow.

If you're building a nostalgia street rod or even a lead sled, you wanna make sure that you have the right wheel and tire combination for your vintage theme. Now, Coker tire has this wide white wall radial that comes in nine different sizes and it'll give you the best of both worlds, good looks and contemporary styling. Now, the white wall which range from two and a quarter to three inches

and to keep the cool classic look, we had this one mounted on the chrome reverse wheel with the baby moon cap and the prices. Well, that's gonna vary depending on the wheel size.

A few weeks ago, we brought you highlights from one of the country's premier drag racing events, the world street nationals. Well, if you wanted more powerhouse video workshop has a two disc DVD set featuring every burn out every bumper, dragging wheel stand and all the winning runs.

They have sets with complete coverage of other hot racing attractions too. And, well, all you gotta do to get one is race to your computer and log on to their website.

Well, we reached the finish line of this week's show. But why don't you join Mike Chuck and me next week for more horsepower TV.
