CORR Pro 2 Race Truck Part VI - Finale. Off Road Expo Winners from Pomona

It's 800 horses ready for the starting

G

today on Xtreme 4x4, the final installment of our core Pro two race track.

Plus we'll find out what happened to our big winners at the off road Expo.

That and more right now on Xtreme 4x4.

Hey guys, welcome to Xtreme 4x4. And if you recognize this truck, you know that it's most commonly seen out there on racetracks competing in one of the most aggressive forms of off road racing out there.

Championship off road racing is short course, door to door, hardcore action where a truck like this sees more damage in 15 minutes than a regular truck will see in its lifetime.

If you remember, we're building this truck for two reasons as a tribute vehicle to a great racer who left us too soon, Jason Baldwin,

and also for the guys at core to take around the trade shows and events to let people see exactly what a pro two race truck looks like. Close up.

It all started with a rolling chassis that we got from Tony Vanilla at North American off road and then we stuffed it full of hardcore race goodies because show truck or not at its heart. This thing is still a pro two.

Now under the rear of this truck is a tube works four inch axle tube quarter inch wall with fabricated center section all out of chrome Molly steel. Now to say that this axle designed to take some serious abuse off road would be an understatement.

Now, the truck is rolling on toil open country mts that are 35 inches tall and they're wrapped around tube works core legal 17 inch bead locks and a half inch thick bead lock ring, as well as protected valve stem and wheel studs will help prevent wheel failure when the truck is on the track.

Now, on all four corners, we installed Bill Stein 9300 series shocks, two and five eights coil

carrier, as well as a matching four tube bypass shock to be able to just the suspension to handle the whoops and jumps on the track. And then we went ahead and built a monster 434 cubic inch Ford small block prepped by the guys over at speed of motive

and then behind that killer small block, we installed one of the hottest drive train set ups in championship off road racing. A huge power glide backed by a gear vendors overdrive unit.

Now, I'm sure a lot of you guys are wondering exactly when did the wrap go on our fiberglass body? Well, you see since the last time this truck's been in the shop, it took a little side trip, it went over to the sea, a show to be put on display there and then headed over to the core race in Prim so everyone could get a look at exactly how far this truck has gone. And today we've got it back in the shop to finish up all those little odds and ends that need to be done and then hopefully take it for a spin.

Normally, a race truck like this would have aluminum panels covering every opening in the chassis,

but that would cover up all the really cool race parts.

And since this is part show truck, we're only gonna skin the driver's compartment with some 0 90 aluminum to provide protection during the hot laps.

Now, a lot of you guys often ask why these projects tend to take so long to get done sometimes stretching out over a lot of shows. Well, the answer sometimes is just the fact of remembering to order every little part we need to build the truck. You guys know what I'm talking about sometimes, no matter how hard you try, you just forget stuff. And when we drop the

and ran the wiring last time, we just plumb forgot to order a starter for this truck. So

we went ahead and put a call in to TCI. Now this three horsepower extreme race mini starter is capable of turning over engines above 11.5 to 1 compression. So once we get this baby bolted up to the engine, we'll finally be able to crank it over.

And once that engine fires up, we're obviously gonna have to keep it cool. So we're gonna mount two electric fans inside a custom aluminum shroud to force all the air through the rear mounted radiator.

Now, in order to get the coolant from the engine back to those rear mounted radiators, we need what's called a transfer tube.

Now, for this truck, we're going to be using some engine, a

thin wall tubing, it'll travel all the way from the front to the back of the truck. That way, all we'll need to do is put a short little rubber hose on the front to connect to the engine as well as a short little one on the back to kick into the primary radiator by using one piece of tubing for this long run will help eliminate leaks when Ro in the track.

Yeah,

we're going to have to put the bender on the list.

Once we have the tubing snaked through the chassis,

we'll build some mounts to attach it onto the roll cage. Since the drive train as well as the radiators are solid mounted in this truck, we won't have to worry about vibrations, shaking anything loose.

Keep it tuned to Xtreme 4x4 when the after burners are lit on our race track.

But up next, we gave them the parts. Now, see exactly what Jessi and Tim did to go extreme.

Welcome back to Xtreme 4x4. A

few years ago, we surprised to lucky guys at the offer expo in

California with a slew of free after market parts. One drove a classic Bronco and the other, a late model dodge.

Well, two years later, we wanted to see how Tim and Jesse's doing with their projects. So in reunited with the guys and their trucks at the Pomona Fairplex

for three days. The Pomona Fairplex in Southern California hosted the off road Expo off Road Expo is now in its eighth year. And what started off as a half a building many years ago was now going into eight buildings representing every aspect of the off road marketplace. Drawing thousands enthusiasts came to check out the latest innovations. You've got people at rock,

you got people that drive around

the track,

you got race car drivers

is the whole gamut of off road is here. Two years ago, we met Jessi and Tim

who were at the show, getting ideas for their daily drivers. They asked me if I would like to spend the day with them. I said,

hey, why not? We checked out some killer upgrades. You know, I thought you guys were just making a segment of the show and I was just a part of it. It was really all I thought little did they know their life was about to change? I was only expecting a T shirt or something I would have been happy with that. I was just happy spending the day with him just walking around

being on TV. They left the off road Expo with more than just a T shirt. So I want to thank you guys for hanging out with us this afternoon. But you know what? You guys can do one more favor for us.

What is it, Jessi?

Go pick up those parts that we all got free,

man. They're all

you guys.

I was amazed, I was speechless. I really didn't know what to say. I had no idea that I was getting any of that stuff. Uh So yeah, it truly was a surprise at the end when you

awarded us. Basically with all that stuff. Jim's goal for this Bronco

was always modest. It's a family vehicle. It's not something I'm gonna just go into a rock crawling competition or anything like that. It is something that I can take the family camping and off roading with and be safe and have a good time. That's what I bought it for and that's what I intend to do with it. Just like that. His goody bag took his Bronco from 68 stalker to full on rocker seats from Mastercraft tires from four wheel parts, wheels from the trail ready. And uh DC Broncos with suspension lift on his own Tim installed Detroit lockers in the rear and upgraded the motor. What was in

a 42 89

2, 89.

Now it's got a, uh, Ford racing crate motor

340 horse 302302. Yes,

I like the outcome.

Uh, it's going in the direction that I want to go, which is what I want. And, uh,

I, I love it. Tim isn't the only one smiling from the driver's seat of the newly modified Bronco shift shift

shift. It

really, man, he loves that truck every time he sees a Bronco, it's like your daddy. It looks like just like yours,

you know. And uh he loves a Bronco and uh,

when you got a chance of driving it on the way up here, he's just uh, yay, you know, he's, he's, he loves the man

fresh off, dropping 26 grand on a new quad cab. I like to go fishing. I like to go camping

and it's quite hard. It's kind of hard to do it in a car. Jessi had planned to go slow on the upgrades. All one lump sum is kind of expensive like a little at a time when I can afford it to build it up while I want it. Instead. He left Pomona with shocks and a lift from Fab Tech as well as tires and rims from Mickey Thompson looks like when people see the truck, everyone think it's cool. Oh, I get compliments when it's clean or dirty.

That's what you wanna hear, man. I also loved hearing how these guys did it themselves. Even if someone else picked up the tab, it was a piece of cake, just reading directions,

having the certain tools that you need.

No problem. Extremely happy. Everything went on very easy.

No surprises.

The

son was just two years old when we first met him and he is still such a cutie.

Keep watching Joey because maybe in a few years your dad will hand you the keys to his Bronco.

I doubt it

go again,

man. It's good to hear that motor fired life even if it does almost make your ears bleed. Now, honestly, one of the hardest parts of this entire project has been all the plumbing, everything from the fuel lines coming up from the fuel cell to the 12 different oil lines for our five stage dry sump kit to say I'm getting tired of cutting braided hose. Well, that would be an understatement. So when it comes to our brakes, come up with a different option

instead of making our own braided brake lines for this truck, we called the guys at Crown performance and had them put together as a complete set of steel braided lines with a Kevlar interior lining and a rubber exterior sheath to protect it when it's out on the track. Plus they come crimped with an A N fitting at either end and fully pressure tested. So we know once these are on the truck, we'll be good to go

starting at the two master cylinders, one line will travel down to the main frame rail and A T,

then one line will go to each front caliper

back at the master. A second line will go down the main frame rail to the back of the truck.

A T mounted on the upper link mountain, the rear will feed lines that head out to each caliper.

Then all that's left to do is bleed the system.

Now, a lot of the times people have concerns with running a complete braided line set up for their brakes.

They feel that the line itself can swell under pressure and therefore you'll have a softer pedal than you would if you ran steel hard lines. But we've run this set up on a couple of our projects and the construction of the crown lines is such that it's just as strong as a solid steel line. So you get a nice firm pedal in there, plus this braided line because it can move around in the chassis. It's less susceptible to debris line up from the track.

But if you think we are finished running braided hose, you would be mistaken.

Our huge power glide will be generating some serious heat while out on the track.

And to keep that in check, we'll be using a fin and plate cooler from Earls along with dash six braided hose

and to make sure our trans fluid stays in the trans where it belongs. We will use a new locking dipstick from

Loar that lock tight once installed

in order for our power steering system to be 100% efficient.

Our pulley needed to be the same diameter as the crank pulley for a 1 to 1 ratio.

This meant we had to have a custom one made,

one called a Jones racing products and we had the perfect pulley for our power steering setup.

Now, when it comes to fluids in a truck like this, what you use can actually make a difference. Now, we're going to be using Royal Purple, full synthetic lubricants in every rotating assembly inside this truck. We'll be using max A TF inside of our automatic transmission to help reduce the operating temperature up to 20 degrees and therefore make it live longer

in the engine will be using X pr extreme performance racing motor oil. It's a little bit slipperier than standard conventional oil and therefore we'll have more horsepower and more torque. There'll be less drag on that rotating assembly. Now, on the rear axle, we'll be installing their max gear, full synthetic gear loop. But before we can put that in, we have to put a gear assembly in that rear.

Keep it tuned right here to Xtreme 4x4 because there's more coming up.

Welcome back to Xtreme 4x4 where we are this close to finishing up our core Pro two race truck. Now, so far we have plumbed every fluid system on this truck. Went ahead and fired up the engine so we could hear that monster roar and now we're ready to slip in a third member into our tube works rear end and then the whole truck is gonna get sent out to get tech checked

for this truck. We knew that we needed a pretty serious center section.

Since the Curry Family competes in core racing, we knew they were the guys to call,

they spec out this 49 plus center with a 6 to 1 gear ratios to help haul this truck around the track.

Now, there's a lot to our cooling system. And since our upper radiator is mounted perfectly flat, we need to add a recovery tank that we picked up from summit racing.

Now where we position it is critical, it needs to be mounted above the radiator cap. If we mount it too low, we'll have air pockets in the system causing the engine to overheat.

Now, in order to get the power from the back of our gear vendors unit down to the rear axle, obviously, we're going to need a drive shaft. So we called the guys at Denny's drive shafts and had them put together one of their fully balanced high speed, heavy duty off road drive shafts. Now, it's a fixed style shaft with a slip yoke built into the center and 1350 U joints on either end.

Now, they

vendors unit is designed for a slip yoke style of shaft that basically rides on a output shaft in the main housing. So we're going to install this yoke and then bolt it in to turn it into a fixed style output. Now, this bolt right here is almost as important as the bolt that holds a helicopter blades on a helicopter. If that loosens up and comes out when the suspension fully extends, the drive shaft can slide out of the back of the transmission and whip around underneath the back of the truck causing a lot of damage. So to make sure that doesn't happen, we're going to use some lock type 2760 red thread locker. Now, this is a high strength thread locker and once we get a couple dabs onto the bolt and fastened in, it'll hold it nice and tight and you'll need an impact to get this thing off.

Now, shafts for a core truck are pretty specialized. They're obviously very long and they have to be extraordinarily strong. So

we called the guys at CTM racing and had them build us 2, 300 m axle shafts with a forties flying in to go into our school and a 40 five spline outer for our drive slope. Now, 300 m is one of the strongest materials you can make an axle shaft out of it is a little bit heavier than chrome Molly. And some guys will actually gun drill the center of these shafts to save on weight. In our case, we went for a solid shaft to keep it strong.

Yeah,

here I'll do a Richard Bacon. Are you ready?

You know,

when the guys at championship off road racing called us up and said, hey,

you guys should build a pro two core truck.

I thought, you know, what,

how hard could it possibly be? Just a bunch of tube and an engine meant to go fast around the corner and whatnot.

But, uh, we got the truck here and I found out that it's basically, you know,

10 pounds of crap in a five pound bag.

My suggestion to you is if you wanna go car racing, you're gonna build a prow.

Number one,

you're gonna buy a lottery ticket.

Number two,

you're gonna hire a race team and build you a truck

and you get to drive it.

Now, obviously, before we can take this truck out and dump it on a track, it's going to have to go through what is called a tech inspection,

but it would be a sin to just put our prow

on a trailer without having a little bit of fun in the parking lot.

Next stop, Lucerne Valley, California and a core racetrack later this year.
