Project EZ Boo Gets Some Serious HorsePower

Hey guys, the Malibu or Easy Boo as we call it is back for some race ready horse power.

In fact, our challenge today in the shop is build a motor for it. That'll get it down the eight mile strip in about five seconds. Well, it's been a while since we kicked off this outlaw Easy Street project. So here's a little flashback

after buying the 79 Malibu Bone Stock, we totally stripped it out

before boating on a competition suspension.

After that with the help of Lou for muscle car, we built a complete roll cage

according to Osco

racing specs.

Then after some serious interior work, our easy boo is ready for the next phase

and that's a motor and that's also where we're going to save some serious cash by refreshing a bullet we stuffed in a previous project car called The Supernova.

It was one of the first GM performance parts. 572 high compression crate motors built

and we dropped it in the 69 nova a couple of years ago.

Now we managed to get the car into the low tens on the quarter mile strip in Memphis on a test and Tune day.

Now we sold the Nova but the motor still ours,

in fact, on one of our first tests on the horsepower shop's DTs

dyno,

it made 740 horsepower.

Yeah, but that's not nearly enough to be competitive in easy street competition. So first thing we did was send our short block off to the school of automotive machinists where they honed the cylinder walls and swapped out the stock pistons or these Jes with larger valve relief. And what you can

see down in the hole is they actually moved the ring lace down further to compensate for the added cylinder pressure. Then the heads made a trip of their own to liver noise, motor sports for a complete CNC port treatment and five angle valve job.

The result was a 31% increase on the flow bench.

Those angles untraveled the valve to allow more air velocity into the chamber and the ported and polished intake runners will they allow more air into the cylinder a whole lot faster.

Now, we also installed these crane micro

knotted valve springs with a seat pressure of 225 on the exhaust 265 on the intake. Now, the micro kite process,

believe it or not involves bombarding the metal with walnut shells and the result is less stress, less fatigue and fewer chances of breaking a spring when he's blasting down the track.

Then after installing a RP studs

and a set of Mr gasket, MLS head gaskets,

we can drop the heads in place

and torque them down in phases of 30 50

85 ft pounds.

The camshaft going in this 572 is a micro

kitted hydraulic roller specking out at 737 on the intake 726 on the exhaust with an RPM range of 4200 to 8200.

Next we install a timing set and cover we got from summit racing

followed by the stock harmonic balancer

like the cam. The rest of our valve train came from crane like these hydraulic roller lifters

and the shaft mounted 1.7 ratio rocker arms that feature some really cool new technology. Now, a traditional rocker arm uses a full complement bearing which contains a bunch of small needle bearings. Now, as the rock arm goes back and forth to open and close the valve, the bearing changes directions causing power robin friction

instead of needle bearings. The crane rocker utilizes a polymer matrix composite bearing that rides on this specially finished shaft. Now, this adds exceptional strength, zero bearing inertia and structural rigidity, therefore, less wear and friction which equals more horsepower

with the shaft mounts in place. We're temporarily installing a couple of the rockers for one cylinder

and that's because we still got a measure for the correct push rod length. Now, to do that, we're going to use this little measuring tool

and here's how it works.

With the tool between the lifter and the rocker,

adjust the tool to zero lash,

then turn the crank over and

make sure the valve completely opens.

Ok? And after that,

return it to the base circle on the camp.

Well, now I can remove the rocker and the tool, measure the tool and be able to call in an order for the correct measured push rods.

Oh, by the way, don't forget, you gotta repeat the drill here on the intake side because on a big block, they're different links

while we're waiting on those push rides. I'm gonna go ahead and remove the lifters

so we can spin the motor over and keep working.

We got our oil pump from GM performance and its specked out for the 572. We already attached the pickup and will secure it with this A RP stud.

Now we can go ahead and drop in the windage tray. Now this is gonna keep oil in the pickup area even during the hard launches.

Finally, we can drop this gasket we got from, fell

into place.

Now, the pan we're using is from

Moroso and it's a seven court with the side kick outs. Now this will give us a little more oil capacity and plenty of ground clearance.

Well, that does it for the bottom end. Make sure you stick with us because you might actually be surprised at the power adder we picked for this 572.

You might actually be blown away.

We're back with our 572 build up for our easy street Malibu. Now be competitive in the class, we need to make about 1500 horsepower with this motor. Now, some of you may ask even with the machine work and the improved valve train, how is that possible with a motor that only baselined at 740? Well, we've got a pretty simple three word answer, big bad blower. And here it is a pro charger FW.

It's a centrifugal style supercharger kit with a boost potential of 38 P. Si now one of the most frequently asked questions about superchargers is quite simply what's the difference in a centrifugal style and a root style? Well, here's some animation to show you the inside story.

The roots type supercharger is the first style ever used.

It has a design going back to the late 18 hundreds

inside a case. There are meshing lobes that spin

trapping air and forcing it into the intake manifold.

Roots superchargers are really nothing more than air blowers.

And as you know, the term blower is often used to describe all superchargers.

The centrifugal supercharger on the other hand, uses an impeller driven by a crank pulley and gears to compress air inside the case.

Then it discharges the air through the outlet and into the motor.

This style offers more flexibility because you can change the impeller sizes and the impeller speeds

pro charger by the way is the only gear driven centrifugal blower with self lubrication. That way you don't have to tap into your engine's oil system. Now, the impeller you saw in the video that thing's capable of spinning at speeds of up to 65,000 RPM. Now, the FW comes in a complete kit, but it does vary depending on your application. Now, we're going to go ahead and get started by bolting up this extension bracket.

The purpose of this bracket is to help the blower clear the valve cover.

Next, we can install the main bracket that also houses the belt tensioner.

Now bolt up the supercharger to the main bracket

followed by the pulleys, one for the crank and one for the blower.

We're only gonna have two belts on this race engine, one is gonna drive a belt driven fuel pump off the crank that we'll install later. The other one. Well, it's for the supercharger. Let me show you how it routes. It goes from the blower pulley down to the crank pulley. Now, we're not worried about a water pump because we'll be running an electric one and electric water pumps. Just don't have pulleys.

You tighten the belt by turning the jack screw, incision down the jam nut

with that handled, we can button up our valve train with new push rods,

valve covers

and finally install the intake manifold.

Meanwhile, whether it's for the street or the strip, a supercharged motor is gonna make more power more safely with

an inner cooler.

Now, the term intercooler may be a little misleading because while the supercharger compresses air causing heat,

this thing basically just gets rid of the heat

and heat. Well, that's the number one culprit when it comes to Yep, detonation.

This is a piston that was torched when fuel pre ignited before the schedule, spark ignition. That's a bad thing. Of course. Now, there are two kinds of inner coolers, water to air like we're using on the 572

and the more treatable air to air.

Last year, we installed a smaller pro charger on our LS gun Camaro along with twin air to air inter coolers. A great choice for a pump gas motor with a blower only producing mild amounts of boost.

But when you consider our race motor is gonna make boost levels in the twenties, maybe thirties. Well, we got to go with this more complicated, more efficient water to air set up.

Now we're actually gonna install and plumb ours twice later in the Malibu, but first

here in the

dyno, so we can tune and test our blown 572.

The actual plumbing for the inner cooler is pretty time extensive. So I'm going to show you how we're going to run it from the outlet of the super charger. We're going to run four inch pipe to the inlet of the inner cooler. Then from the outlet of the inner cooler. We're going to run some more four inch pipe to this hat that sits on top of the carburetor.

Now to transfer the water from the ice box to the inner cooler, we're going to use this turbine pump we picked up from Dayton. Now, this thing flows 20 gallons per hour.

Now, in a couple of weeks, we'll have the rest of the parts bolted on and the inner cooler PLM then comes a moment of truth to see if we get over 1500 horsepower.

Well, there's more horsepower coming up. Make sure you stick around.

You

got the biggest variety of heads up classes. Index classes are insane. They just put on the best show around

and be good old American muscle. I just love it.

Well, the shirt pretty much speaks for itself. We're here at Orca's year one series for the first race of the year. They have a bunch of cars, ones with some pretty cool engine combinations and every power adder on the planet from good old Nitrous to high tech turbos and oh, don't forget about this one.

You get the idea,

this outlaw racing thing is catching on like wild

way beyond its southeastern origin.

For example, a team from Houston Texas has joined the series with a 67 Camaro 10 5 car and powered by a 76 2 Fulton Big Block,

not with one, not with,

not with three but four stages of

we leave on one and we try to turn the second one on within one second and the third one on 1.5 and then

put the fourth one on wherever if the track is really good

and you can put the horsepower down, you can use it. And when the track is not very good,

obviously, you're gonna pull power

out of it.

We'll make our first hit, very cautious, very conservative. We'll make more

then come back on the second round and third round and be more aggressive each time. Ok. Always trying to learn for tomorrow

and the crew 10 5 class limited street, another Nitrous Camaro was laying down consistent 480

to leave

the pack.

You know, I love to come out and uh qualify number one. But you know, the big thing is get the win. So that's, that's what I'm after

in the radio. Tire easy. Street class Shane stacks, Herbal charge, Monte Carlo lays down a first round 497

new record in the making.

Yeah, it felt pretty good then. Um we hope we can back it up this next time.

But in round two, his 501 is a few 1000 short of the backup

Ben David Rees in the black Mustang totally steals the thunder running a 492

proving that blowers can still add the winning power.

I prefer a blow

charter over the turbo uh only because

not necessarily the power but just engine management, uh seems to be a little more erasable

in the fastest class outlaw 10 5, the largest field of drivers ever turned out.

They turned them on and put on a show of amazing comfort of upper speed.

There was even an unscheduled fire show at the line. Tough luck but good reaction time driver

and a panel for number one qualifying, won by veteran Steve Kirk with a 454.

All of this setting up a super showdown of outlaw finals on Sunday.

Welcome back to Horsepower's coverage of outlaw racing at Huntsville drag wood.

The crowd's ready for elimination. And among them, we found a couple celebrating a rather important event.

We're here celebrating our engagement.

September

8th

2007.

How nice, how romantic celebrating here at the races.

But wait till you hear how he popped. The big question

sitting at home. It was after an episode of Horsepower TV.

It was,

we're honored, but we've got to get back to the starting line

where it's anybody's race in 10 5 eliminations.

Round three top qualifier. Kirk loses to Mike Hill,

Turbo, Tim Lynch loses to a newcomer to

Warrior.

Meanwhile, a guy from Maryland is nudging his way to the top

here in the left lane beating Jack

Barfield.

Then Baby Hill earning a spot in the finals.

Hoyle was rock solid working his way through the ladder of limited street and on to the final contest.

What's it gonna take today in this cool weather? You know, I think, I think you're gonna have to run some, uh,

mid to high eighties.

Then there was easy streets where a face off between Stack and Reese was destined to unfold.

I try to set the world on fire. We just want to win, win the race

pretty much leave it exactly the same and just see if the

Hare picks it up and if it gets any cooler this time,

it should go a little bit better. Maybe.

Well, talk about your showdown of the weekend,

Shane Stack and Reese now battling out in the final. Wow.

And what a weird final, Reese quickly stages in stack and stack stays put while Reese leaves the core of the tree falls.

Well, too much anticipation, your red lights and you're out.

I really wasn't ready when I went in and I looked up and I was in and I said, man, I'm a sitting duck and by that time he just blasted off and it was just like,

it's all right.

That's all right.

Di

Coyle

didn't run in the eighties but he didn't need to and live his streak winning this final against newcomer Lamar Swindle.

It would have been a good close run. He had a little knocker miss out there about half track. He uh

he actually was out on me a little and uh which I knew he would be his car leaves great. He's a small block and

uh uh I was gonna have a hard time chasing him down but

came out in our, in our favor

in outlaw 10 5 finals. It was Sexton over Todd Moyer after fighting his way through the toughest fuel of outlaws in history.

It was tough. I mean, there's no

Demy out here.

So the New

Oska season takes off with the usual hair raising drills,

the familiar fast car face off

and three leaders of the pack in the quickest baddest heads up street car competition in the world

depending on how you gauge it. This could be the coolest tack that you ever install in your race or street machine.

It's MS D's Needless laser gauge and well, here's how it works.

A tiny motor generates an led light that's controlled by a microprocessor. And the result is, well, you get a circular trace that indicates your RPM s

there's also a built in shift light that you set by touch screen. Now, of course, they also have laser gauges for everything from water pressure to fuel air ratio.

Now, the prices vary according to the gauges, but the tax start at right around $220. 1st. There was the super 40. Now, the super 44 this is Flow Master's newest and latest muffler design. They claim it's the most aggressive, deepest sounding and most powerful muffler made on the inside of the black case. They have improved delta flow technology with a larger flow path radius

on the outside, you can get any offset you want with pipe sizes ranging from two and a quarter to three inch. Now, the price shouldn't resonate you too bad. Starting out at 76 bucks a piece. Well, here's a cool combo from Flex

Aife

that'll free up a little horse power. It's an all aluminum radiator with a two row core design that promotes better airflow and resistance to heat.

Now, you can get one preassembled with a pair of their 12 inch blade fans inside a lightweight nylon shroud and it's got the lowest profile in the aftermarket. Now, together,

they'll not only free up horsepower, they'll give you better gas mileage and quicker warm ups. You might warm up to the price about $770. Well, it's been nothing but cool having you in the shop with us this week, we'll switch gears to another project next time and we'll see you then.
