We're at 1033 at the wheels.
I think it's about 730 horsepower.
Welcome back to this versus that.
Today we have a very special matchup.
Exotic versus exotic sounding.
Really expensive versus not as expensive but still expensive.
Will not break, might break.
If it doesn't break, we'll smoke.
Wow, that was an intro.
I have no idea what it could possibly be.
You know, we got a returning guest here, Mr. Rob Dom.
And he did a hood delete mod this time.
If you guys remember Rob's last time here, had a little bit of a hood issue.
Same dude, slightly different FD this time around.
Actual FD this time around.
This is the infamous three rotor from the channel.
I've had this on my YouTube channel forever.
This is like your baby.
This is what people know you for initially was this car.
For those who don't know, we got a three rotor in an FD RX-7.
What all do you have done to this thing?
This is kind of like the dream, I think, stock body FD setup is that you have a three rotor,
which was a production engine over in Japan, not in the States.
What did it come in?
It came in a Yunos Cosmo.
Yeah. Cosmo.
It looks like this gangster.
The one with the back seat looks like a bay liner.
And the whole interior looks like a concept car.
But like actual.
It's like if Mazda made a sword.
In my mind, it was meant to be in an FD and the FD was meant to have a three rotor.
It looks like it fits really well in here.
It really does.
I actually, since Hertz last seen it, I have power steering.
So I'm really proud of myself.
I'm going through the 12 steps.
This thing has been my test bed for testing everything
that you saw when I raced Ken in the four rotor.
All of my tuning testing, I do it on this one.
What you're saying is this is your shit car.
Yes, yes, it is.
But mostly because I built it.
The engine is actually the first engine.
It's a prototype engine for me built in-house.
So not only did I assemble it, but I also machined it.
So everything on my CNC machine, like I'm trying these things to
to really just like vice grip this whole thing all together and hold it.
What power are we making with this thing?
So I was not lying last week when I told you guys it was at 850.
I put a new G42 1450 on there.
Spoolie boy.
You can't not.
It works.
Good check.
We're at 1033 at the wheels.
800 foot-pounds of torque, which is truly unheard of.
These little things make 800 foot-pounds of torque?
Whose idea was this?
What RPM does it make 800 foot-pounds of torque at?
That's what I'm trying to prove is that rotaries can make torque.
And that's at 6,000, 6,300 RPM.
What does it rev to?
It revs to 9,000 right now.
That's a meaty power band.
Yeah, oh yeah.
That's pretty loud.
It carries 700 torque from I think it's like 5,200.
One thing that makes this race very interesting is that my manifold was designed for a much
smaller, less efficient turbo.
So I have boost creep.
So I can't control how much power I'm putting down.
So if you guys say, hey, why don't we tone it down?
I can't.
Just all right foot.
So the problem is I'm going to have a hard time hooking.
OK.
So what trans do you have that's taken all this power and lets you do all that?
Until I hit 700 horsepower, I was using the stock trans.
OK.
And I started separating them in half.
They split apart.
Now I've got a T56 Magnum.
So it's a TR6060.
With a Ford 8.8 independent rear end.
Nice.
What gearing?
Ford Explorer.
And it's a 5.12.
So it's a very short gear.
Wow.
OK.
Because of how high the engine revs and finds torque that makes sense.
Yeah, yeah.
Otherwise, first gear would go to like 200 miles an hour.
Yeah, right.
What does this thing weigh?
You know, I would honestly guess it's over three, but right around.
You know, because the stock FD is 28 and change.
Yeah.
And the three rotor does add another 150 pounds.
What are you running for rear tire wise?
You got some meats on this thing.
Yeah.
So I didn't know if I would get disqualified with these.
So I brought some drag race.
Again, another person disqualified.
There are no rules.
We don't have any rules on this show.
These are zero rule book in the entire series.
Well, when I raced Ken, those were radials.
Yeah.
This is bias ply, but they are DOT legal.
Yeah.
What are these, 26 and a half?
I think they're 28, but they're 11, 10 and a half?
11 and a half.
Or 26 by 11 and a half.
I just love that stock FD wheels make the best drag wheels.
They really do.
You see them often.
Evo's run them all the time, right?
They're popular on the Evo.
Only 16 that could fit over the roof.
You got any other weight reduction?
You got some carbon doors, but you got full interior.
I don't have carbon doors.
I have carbon door.
What's important to note about that is that no roll cage, carbon driver's side door.
Cause that just says that Rob doesn't care about his own safety.
No.
His passenger he cares about.
No exposed drive shafts this time.
Oh yeah.
Has this car done anything other than drag racing?
Yeah.
Yeah, totally.
Are you sure about that?
No, it really hasn't done much street driving.
That's about it.
Did you street drive this thing?
Yeah.
At a thousand wheel horsepower.
Yeah.
All right.
I respect that.
You know, no one bats an eye when a 2J guy says he's street driving his 1000 horsepower car.
Like let's put some respect on the Dorito.
Thank you.
Well, we got one homebrew race car and let's see what a factory race car looks like.
My name is Alex.
I'm from TAG Motorsports in San Diego.
This is our 2020 48 Pista.
This is a beautiful car, man.
Talk about aero.
Look at this thing.
You ever seen a cooler like that?
Just laying flat, but somehow it works.
It's got a cooler and then another cooler down there.
It's at just slight enough of an angle to eat that.
Yeah, just slight enough of an angle.
You can kind of see it.
And it actually pushes the air outside from here on the sides.
Oh, so it also gives you a little bit of...
Oh my gosh, so this is a functional vent here.
Maybe a little bit of downforce there or something.
A lot of vacuum.
Is that stock or is that aftermarket?
That's all stock, yeah.
So the only aftermarket part on the front end is...
This piece is...
It's got the full Novatec aero kit.
This piece is added.
It's a little bit further out.
That wasn't carbon originally.
So you said full Novatec aero kit.
What does that include?
Because we don't even know anything about these cars.
So what's not factory?
The little added carbon in the front side skirts.
A little added carbon on the mirror and the little triangle.
Lights are on the taillights and the rear spoiler.
These wheels look sweet.
What are these?
So these are HRE's vintage 527S's.
So it's their new two-piece line.
It looks great.
I love them.
We're using the factory titanium lug nuts.
I did not really anticipate all that stuff.
You do have an advantage with the quick shift trans.
Is it a 7-speed?
It's a 7-speed dual clutch, yeah.
When everything's all running and warmed up,
it's really cool because it learns the service that you're on.
Wow.
So every time you put it down, it just learns more and more.
Does your car do that?
Service.
No, he's going to gain on every shift I've got.
What kind of power do these make?
I think it's about 730 horsepower.
How much does it weigh, do you know?
Just over 3,000 pounds.
Wow, this thing's pretty light.
Can we look at these seats?
You've got blue suede seats.
Yeah, so this was a...
I don't know how that door handle works.
This is a fun thing.
We did a project with Ferrari's tailor-made.
We got an old-school Ferrari fabric all on the floor.
Here, give that a sniff.
Oh, I smell it from here.
It smells brand new.
It's actually taking money out of my pocket.
Yo, can we appreciate this back here?
I love that you get to see the engine.
What are we looking at?
V8, twin turbo, right?
Yeah, 3.9 liter twin turbo V8.
3.9 liter V8 in itself is so small.
It reaches max torque at 6,750
and it's got this boost by gear basically from the factory.
Third and fourth gear are completely different than first and second.
It's absurd.
So you got a V8, bigger motor, and more turbos than him.
Yeah, and 335 street tires.
I'm not finished.
On 22s, so let's see.
He's got one piece of carbon fiber.
This on the other hand.
This has more carbon fiber in the taillights than he's got on the car.
It has more carbon in the engine than it has...
Look at how much aero is in the taillights.
That's like everywhere you look is aerodynamic on this car.
There's active aero underneath the diffuser.
The diffuser comes all the way up to here.
They did a killer job with this.
So you said 335?
Yeah, I run a 2021 setup sometimes and I run a 355 in the back.
So it probably grips off the...
It does, yeah.
Yeah, it moves.
All right, so obviously these cars are going to hit some pretty high speeds on this track.
It's up to you guys if you want to do heads up, how far you want to go.
You got 500 foot, 1,000 foot, and then there is a 1,500 foot marker.
So up to you.
I'll go all the way.
Yeah, yeah.
That sounds fun.
I mean, just when parts are going to fly off, which direction are they going to go?
Because I want that lane.
Ouch.
Yeah, I think 1,500 works for me.
1,500 from a dig.
Let's do it.
I think Pista is going to get the hit because of its sophisticated traction control.
But 1,000 horsepower up top is going to fray train it.
So I'll go with Rob.
I mean, I got to kind of go with my own car, but the facts are the facts.
So I'll take myself.
I got Rob Dom.
Always bet on black.
We got a FD RX-7, fully built three rotor, massive Garrett turbo, over 1,000 horsepower,
all the torque, and character and heart.
So I just have to give it to my boy Rob Dom.
Let's give it up for the six-speed heroes, all right?
We need them to hold it down for us.
I know everybody went with the rotary, and I got Italian blood in me.
So I'm going to go Ferrari.
I don't like supercars, so I'm with team Rob.
Bacon is definitely going to win by a long shot.
I'm going to go with the one that doesn't have pistons.
You know, I got to believe in myself.
I'm going to stand up, be a man, and say that I think I'll take the win.
I hope I take the win.
Yeah, I may have messed up on my guess.
Would you go?
I went with Rob.
Yeah, I think we all went with Rob.
The thing about Rob when we landed on this last time is he's all in, right?
He's all in.
Yeah, he's not going to buzz you off.
Good?
That was squirrelly.
He didn't really warm up the tires good either, though.
Well, Rob left as a driver, and he's coming back as a passenger.
Also, Alex jumped the hell out of that.
Oh, yeah.
It's...
Chase is a race.
Chase is a race, yeah.
Chase is a race rules.
We have no rules here except a chase.
The rules are we make the rules.
You want to switch to the other tires?
Yeah, other tires.
What other tires did you bring?
Drag radial.
Oh, yeah.
Dude, we saw you come loose on like in like fourth gear.
Traction doesn't help if I can't stay in a straight line.
Dude.
I want to bring the all-wheel drive four-rotor back out.
So much easier.
Looks like you've done some street racing before because you
jumped the hell out of that arm drop.
I mean, listen, he said when he moved, so I didn't know...
I moved, yeah.
The elbow twitches.
Listen.
All right, so they're going to go change the tires.
We're going to shorten the track to a thousand feet.
Rob says the thing's getting really kind of wild past a thousand foot.
Wrinkle walls with a street tire on the front usually is a good combo.
I think drag radial will be better.
Do you think wrinkle walls with a bicycle tire is the better combo?
I'm pretty sure you're not supposed to run a mix of tires.
I don't know why.
I think it's because of the way the car reacts.
Like maybe the slosh in the front helps also.
I don't know.
I'm sure the common well that's never driven a car before is correct.
I don't know anything, so...
All right, everybody ready?
Okay, ready, ready.
So...
Holy shit!
Wow!
That's a first.
What did he say about switching tires for more stability?
Jesus, this thing is scary.
You almost hit him.
Did it look different from our perspective?
Was he far in front of you when you almost hit him?
He was close, but it felt better.
It felt much better.
I don't understand that.
The launch was good.
Your launch was sick, man.
You got out.
Like I said, this turbo's making so much ******* power that I can't control.
I haven't tuned that out at all.
What's your insurance policy like?
Yeah.
So the Ferrari took the first race and the second race.
Best out of three.
So we're throwing in a bonus race.
What we're going to do is we're just going to do a roll race to the 500.
That's what Rob wants.
See what happens.
Bonus round.
All right, so now we've got a scumbag, Amanda, just doing donuts.
Just go right into donuts.
Right into donuts.
Rally car.
So you won.
That means you've got to do some victory donuts.
There you go.
Turn the switch.
He sang the song, though.
He sang the song.
It sounds so good.
That was, I wasn't expecting that one to-
You didn't light up.
Yeah, I wasn't expecting him to hold on to that.
Is that a YZ250?
No, that's a CR500.
