Hey, we're not horsing around. We're looking for some serious power for you. Late model Mustang guys

today on horsepower TV,

we'll puff up the power in a late model Mustang with a cold air kit,

power pulleys oversized throttle body and high performance exhaust

in our race of the week. It's a blowout in the bluegrass state

with NSC, a competition from Bowling Green, Kentucky

and how lead still leads the way in this shop when it comes to Street Rod retro projects.

So hang on for horsepower TV.

Hi, welcome to the show.

Mustangs made their mark in the horsepower history books. Thanks in part to cars like this GT 350.

Of course, the legendary Carol Shelby put his magic touch to this one back in the muscle car era.

Even in the computer age though there are ways of giving newer ponies more power.

Yeah. Now, back in Shelby's days, increasing the efficiency of both the intake and exhaust flow had a positive effect on horsepower and well, the same thing still holds true today.

Now this 99 GT uses a high tech 4.6 L overhead CAM V8, but

we can help out its intake with this can and cold air induction. Now, it includes a high flow plastic duct

billet, aluminum air horn

and an air box to help keep everything shielded from engine heat plus their million mile filter charger.

Now, we're not gonna stop there. Of course, we'll also add an oversized throttle body, an adjustable fuel regulator, some power pulleys and even a high flow exhaust system. But first, we need to get a baseline on our dyno Jet here so we can track those improvements.

Ok. We peaked at 206 horsepower. That's our baseline.

All right, I'm ready to start spinning some wrenches.

We'll get started by disconnecting the battery.

Then we can turn our attention

to the intake track. Now, the first thing to go.

All right,

is the air box

then disconnect the wiring

and the hoses

and loosen the hose clamp. So you can remove the ducting from the throttle body

to match the increased air flow of that cold air package. We're installing the 70 millimeter throttle body replacement for BBK.

It's CNC machine

and it features factory style direct fit linkage. So there's no fabrication.

Now, we're working on a 99 GT which has an internal fuel regulator, but if yours is a pre 99 well, this replacement is a good idea.

Since it's adjustable, you can increase the line pressure and give your motor more fuel to compensate for that increased air flow.

Of course, once you get the throttle body off the intake, you can go ahead and loosen these two screws. Now, what that's gonna do

is allow you to take the throttle position sensor off the old throttle body.

There we go.

So you can attach it to the new one. Speaking of which, compare the stock throttle body

to the 70 millimeter piece. Man. Quite a difference really is. Now that alone ought to be worth quite a few horsepower,

but I'll tell you what, while you're putting this on,

I'm gonna get that cold air package ready. Good idea. Now, before we put it on though, let's use this bushing that comes with our kit

that's gonna help keep everything lined up. Then using the screws also provided,

we can go ahead and reinstall that sensor.

Then using the kit's new gasket and screws.

You can both the throttle body to the intake

and reconnect the factory linkage

and throttle position sensor.

Well, now we're ready to install our cold air induction system.

I've gone ahead and pre assemble it

with a mass airflow sensor and the cold air box. Now it just goes right in place like this.

Once you've stretched the rubber coupling over the neck of the throttle body, you can go ahead and tighten up the clap there. I guess that's good enough. Now, up front here, the support brackets attached to a stub that's mounted on the end of the head.

And over here

all we have to do is reconnect the sensors

that ought to do it. And

finally these emission lines connect up using hose extensions that are supplied in the kit.

Then you're done.

Yeah. But we're far from done with this late model Mustang build up. Stay tuned. We'll be right back.

Everything from high flying Mustangs to six second Pro

Monsters in our horsepower race of the week

and carrying the torch of time tested restoration.

We'll visit a shop out west where letting is leading the way in restoration work

for the latest news on horsepower TV. Check us out online at horsepower tv.com.

Hey, welcome back to the shop and our high tech hop up on this late model Mustang. Now we've already added a cold air induction package and a high flow throttle body. Now we're getting ready to free up a few more horsepower

with this underdrive pulley kit from BBK.

Now, Joe's already busy getting the old pulleys off and here's how they work.

Well, our new crank shaft pulley is smaller than the stock one back. Here's a good comparison for you.

So each revolution that turns the belt a shorter distance. On the other hand, our new water pump and alternator pulleys are larger than the stock pieces. So it takes more belt movement for revolution. Well, the bottom line is, it takes less horsepower to turn the accessory system

because everything slows down about 20%.

That's right. Now, I'm not gonna slow this project. Down. I'm gonna get going on these police good deal.

Now, before you install the alternator pulley,

make sure you put the proper spacer in place and that's included with the kit

and slide the pulley

and tighten up the nut with an impact wrench

the water pump pulley is next.

Now, tighten the bolts evenly to avoid distortion

and torque them to about 15 ft pounds.

The replacement pulley boats right up to the harmonic balancer here and oh, here's a tip for you.

If you soak this whole thing in hot water for about 20 minutes, well, the assembly will expand and allow you to slip it over the cranks now a lot easier

and it looks like our hot water trick worked. Now, we just need to torque this new longer boat down to 60 ft pounds.

Now, the final step is to reinstall the belt and to do that, you first got to remove this little guard right here.

Then you can use a ratchet

to rotate the tensioner out of the way

and reinstall the belt

using the factory diagram as your guide.

Well, that takes care of everything under the hood. Now it's time to get under the car and get that factor exhaust off

this factory H pipe actually holds back horsepower with its four Cats and

well, all the usual kinks and bins.

This X pipe. On the other hand, is a new design for BBK that uses only two high flow cats and 2.5 inch mander

bin

iIn tubing.

Ok. Hey, you wanna hold her up back there?

I'll hold up my end of the deal. All right. Yeah,

to make it up in there, it looks like it's gonna fit pretty good. This thing gonna be

nice.

The rest of the exhaust comes from flow master. Now, check out their delta flow muffler.

The extra baffling right here is gonna help reduce interior noise at light throttle. But when you mash the gas,

hey, you're gonna get full power. And that familiar Flowmaster rumble.

Now, the tail

pipes

quite an improvement too. About 25% bigger than stock. And of course, man

bent for unrestricted flow.

The hangers here plugged right into where the stock ones went and well installation is as easy as we'll get my partner to do all the work.

Now, remember our baseline horsepower was 207

to see what a day's work in the driveway will get you.

Wow. Over 235 horsepower at the rear wheels.

Yeah. And the entire hop up including cold air kit, throttle body pulleys and exhaust

would just cost us a little under $1200. Hey, that's a whole lot of giddy up for the buck in my book. Easy for you to say. But hey, we got another chapter of horsepower TV coming right up

next. When the amber light changes to green, the cars change to fast charging creatures. Stay tuned for a street car blowout in Bowling Green, Kentucky

tv's race of the week is brought to you by car parts.com.

Everything for cars, trucks, vans and suvs.

All right. Welcome back to Horsepower TV. And the Bowling Green, Kentucky, we'll get ready to load up for a bluegrass shootout.

It's part of the National Street Car Association, street legal racing series.

Everything from pure stock to the pure madness of Pro

Moz.

The NSC A has sprouted a hot grassroots racing series with 12 classes of a quarter mile competition. A

kind of series fans and serious weekend racers have been waiting for

one that's designed by racers with three goals in mind, laid back atmosphere, family environment

and good competitive racing. So

we uh

put an association together based on exactly those principles

and

put our money where our mouth was and

carried on. And

this is the result

owners and, and the people, the staff of NSC A has been very good to all the racers and the fans. So it appears that these guys are doing a very good job. That's pro Streeter Danny Scott who has a shot at the season's points championship.

But first, he's got to catch the leader. A raging Cajun from Louisiana named Paul Dreon

with his 630.

To

me

that he pilots with a power glide,

the car stays in its normal form. It has been

in, I think we will be something to beat this weekend.

Well, looks like Scott's going to have to get his NS

act together to qualify big

and he will. But there are other opponents to watch out for too.

Like an summer who would later hit a weekend top mile per hour mark of 211.

And Pat Me

is competing against himself.

He's a man, newer firebird.

Tony

Gentil is driving his crusty

old Camaro Spinach can, we haven't had to run each other yet? We've been on the opposite side of the ladder. But, uh,

you know, he's gonna race. I'm gonna race. That's the deal.

You know, in FC A classes qualifying Grus were wild with no hose bar.

In fact, these pro

nostalgia guys are wheels standing mad men. Uh, excuse me, while I kiss this guy.

Outlaws are just about hall in the low sevens

at the nis

pro mod guys. Well, how about 656 at 211 miles an hour

or 650 at 215

or Billy Harper in the far lane with this clock qualifying 648 and 11. You pay your dues and, uh, things are starting to come together for us and, uh, we're having a great time with it. This is my birthday. So we're gonna celebrate with a win.

Well, don't cut the cake yet, Billy, you and your Barracuda have got to get past points leader Wayne ST

who's got over 2000 horsepower in his well tuned bet

as the sun heats up for today's eliminations. You can bet the top guns are taking aim for a spot in what should be some red hot finals

in Pro street top qualifier, Mui

continued laying down ETS and the Sixes

as he socked into summer

and then Scott on his way to a showdown against Hugh GED

it on a

teel

in the other green car. What's your strategy gonna be to beat this guy down?

I gotta get him on the train

in pro

mod. It would be a shootout between Harper the veteran and his carburetor. Ka

and Harold Martin, a former GM engineer who built up his own fuel injected firebird. The track is becoming very tricky and uh

it's truly gonna be a challenge to try

to sustain good traction to try to not overpower the track

and yet make a good run. Martin not only has racing talent, he's got racing jeans. His mentor, a crew member is Dad Houston.

I remember when he put the fuel injection on it three years ago.

Uh It was island too low for me. So I grabbed a screwdriver and went to dial it down by that time he hit the computer, I thought, oh, I better get the broom.

Meanwhile, who's gonna sweep up here in the NSC A finals

in Row Street? It doesn't get much closer than this

gel

edges busy

by a few thousands with a 698 to take his second Rose street win in a row.

Pat's a tough race. He's been doing a long time. I mean,

so happy I beat him. You know,

then the pro by duo

Harold Martin powers his way to a 6 56 213 mile an hour. Wind over Harper keeping his championship hopes alive. You know, the trap was tricky. We didn't want to overpower, but we also wanted to make sure we put that Ac Delco car in the winner circle

next stop Stanton Michigan. And we'll be there when these quarter mile street fighters square off again

in the nation's hottest new racing series.

Welcome back. You know, when it comes to new cars, plastic might be fantastic. But if you're working on a steel body classic, well, nothing beats classic craftsmanship.

Now today Joe's gonna take us to a shop in Wyoming where they still teach the traditional tricks of customizing.

This. Ch 48 Ford's been customized the way rodders used to do them back in the fifties, for example,

look, no seams here. Now, back at the factory, they used to use welding like this when they bolted fenders to the bodies.

But the owner of this rod found his seamless look thanks to a lost art called letting

the owner is Wyoming tech instructor Matthew Harris, who's going to demonstrate the process for us on this old Studebaker.

Well, letting is really a means of, uh, applying a filler to a panel to perhaps raise a low or perhaps, uh to

uh fill in a seam or something like that on a factory type vehicle. And we do it through a means of an alloy between the lead itself and the small quantity of tin.

After welding on the seams to be leaded, he grinds on the wells to ensure a clean vine.

Then he removes all the paint about four inches from the area with a vertical sander.

Next, he puts some tooth to it.

We need to hit it with about a 24 grit disk to kind of create a rough surface to ensure that that lead has something to bite into

to further clean and prep the area Matthew applies acid to the heated surface. A process called tinning is next

with our lead stick. We're going to heat that up and the panel slightly

uh to the point where the stick is going to reach the molten state or the liquid state.

And what that's going to do is allow us to apply a thin layer of lead over the entire region that we're going to apply. The fill to

the actual letting is next where the stick is heated to the consistency of spread of butter to fill all the voids.

A wooden paddle is used because it won't absorb the heat

as anything cools, it tends to shrink. So typically we'll apply a little bit more lead. But to the general contour after it is cooled, we'll come back

and actually use a body or Vixen file to actually file the lead down to desired contour.

And this whole bullet nose is really shaping up. Matthew, great work. And I think now we can see when it comes to a real classic look. L is still ahead of anything else.

And now you know why they call them Fled sleds. Good point. And we've got more good stuff coming up. Stay with us.

Now, horsepower's hot parts brought to you by Summit Racing equipment, your source for high performance parts for 30 years.

Today, we've crowd a whole herd of hot parts for you mustang lovers. Now it should come as no shock that Edelbrock has just introduced a version of their performer ias shocks just for you. Now, they're available for both the front and rear of late model ponies. And the mono tube design will help you get a handle on the road without putting the arm on your wallet. Now, they're under 100 bucks a piece.

You can get a handle on some more horsepower. With this extreme off road pipe from flow

tech,

it's a full 2.5 inches of aluminized man

bent tubing

and this X design scavenges exhaust more efficiently by taking advantage of low pressure pulses when each cylinder fires. Now the result is more power, more torque and a sound that may remind you of a set of NASCAR 180 headers. This kit won't exterminate your budget at under $200.

Well, now, Mustangs with modular motors can harness that horse power. With this new dual friction clutch assembly from center force.

The clutch disk uses a different F

material for both the fly wheel and pressure plate side And the pressure plate itself uses these weights to increase clamping power as the RPM increases.

Well, now you can have the best of both worlds, a light pedal and maximum grip for under 400 bucks. All right. Well, it's time for us to get a grip and show you what's on next week's show.

We'll get back to our purple 32 Street Rod project by working on the wiring

the lights steering column and glass

in our race of the week. It's a street car shoot out near motor city and we'll see who is the pro street king of the hill. Plus, we'll show you how to replace that rusty old quarter panel without even using a welder.

Remember? High performance fun is what this show is all about.

Ready to take these mustangs for a ride. Yeah, but I bet this one gets around the track a lot quicker than that one does. We'll soon find out

for information about the products used in today's show and more. Check us out online at Horsepower tv.com
