Building the Ultimate 1000hp A90 Toyota Supra With Steph Papadakis

in six months you tripled the horsepower, yeah right that's what I'm hearing and when you're done cleaning don't forget to seal it with Voodoo Ride Nanotechnology Sealer, safe on all exterior solid surfaces, easy spray on and wipe off . provides superior hydrophobic protection that lasts for months here's a truck that hasn't been cared for and is 45 years old look at that shine coming out follow the link below get yours today it's on amazon so it's easy stop being lazy clean your damn car get these products and more by following the link in the description, welcome back to a new season of construction biology where we take a look at the wildest rides we could find, no expense was spared with our set design, but where we put a little extra effort is with our latest and greatest host, Tim Barisha of BBI Autosport.

Oh, you're going to shoot fire for us. I worked at Porsche Motorsport for a period from 03 to 07 and shortly after I started with Bbi, you know? something about how to make Porsches go fast and how to get them to the top of Pike and set records. Yes, this is what happened. I got a text from Brian Scott and he said, Hey, can you be in the garage at 3 p.m.? I was like. uh I'm sure nothing happens after that I appear here we have the one between two ficuses and what do you have for me? I bring the heat today because I'm a Honda fanatic.

I brought the man himself,

steph

papadakis

, but not him. He's not messing with Hondas anymore, he's messing with a company called Toyota and he's messing with new

supra

s. We had the opportunity to get to his shop, beautiful facility and it's the first time we'll get out of the donut garage and see cars outside in nature. You're saying we're not going to film here, no, we're going to go to Steph's store and actually see how he does it there. I'm a bit of a newbie to the fd scene and the import scene, uh, tell us. a little bit about how we got here to talk about this together so my story started with import drag racing so front wheel drive drag racing in the late 90s early 2000s we had a lot of records and then We moved on to rear-wheel drive drag racing. 1600 horsepower turbocharged V6 around 2005 2006 transitioned into drifting wanted to do something different and built a drift car started working with Tanner Faust built him a drift car and the team just got into drifting .

In a few years we won a couple of championships and I started working with Toyota Cyan at the time Tanner Foust retired, we started working with Frederick Osbo who drives the Supra and won a championship with us and we have been going strong since there a compression of about 20 years of what We're here now, that's amazing, but let's talk about this car, it's a new

supra

, it's amazing, beautiful execution from what I have to poke around, but teach me a little more about the focus of your guys and the challenges. Let's start there, we got our hands on this car in mid to late 2019 with the idea of ​​taking the engine out, the B-58 engine, the inline six and then trying to make a thousand horsepower because the first step we said in being able to race the supra and form the drift competition was getting enough power out of the engine, we took it out, we knocked it down and by the end of 2019 we were able to make a thousand horsepower out of it in six months, you tripled the horsepower, yeah my philosophy With motorsport being number one, you need to make sure you have the horsepower you need to be competitive.

Number two is going to be that you're going to need to have the tire that you need to be competitive, so can you fit the size of tire that you need? in the car and third, you want to have the weight, you know, what's strange is that I feel like the suspension geometry and some of that stuff takes a backseat because you can get away with poor suspension geometry if you have good power and excellent tires, well, come on. learn more about what your challenges were starting with one engine and tripling the power and trying to make something reliable and take advantage of the abuse of the fd circuit so that the factory engine in the 2020 supra makes 335 horsepower, it's a straight six, all aluminum and Our goal was to make a thousand horsepower, so we took the engine out, took everything apart and started looking at, what are the parts that we need to change and what are the parts that you know we can keep and What are the factory ones?

The crankshaft block, all of that looked like it could make a thousand horsepower, so we changed the rods, the pistons, the cylinder head bolts, we changed the exhaust cam valve springs, that was the main change we made to the long block engine, so once we have the complete engine and we say okay, this engine itself, the long block can handle the horsepower and now we have to get that horsepower right and we use the borg efr turbochargers and we would choose a turbocharger that makes around a thousand horsepower in total, rather than putting in a 1200 horsepower turbocharger and making a thousand that could have better efficiency, we tend to try to extract as much as possible of the turbocharger.

Basically what we're doing is using a smaller turbo than you would normally use in order. so it has more response at low rpm and gets boost sooner and all of these things and loses some of the efficiencies at higher boost so maybe we have higher intake air temperatures in the engine which could reduce the power, but we will change some of That high power reduction is suitable to get low rev response and a little more torque in the low end, yes, I see, so you want, you are

building

that curve and you want to have maximum efficiency with the highest amount of usable power instead of that peak. number and we will sacrifice some of that maximum number to get more of that download, that makes a lot of sense.

I'm looking at some 3D printed things. Does it help speed things up instead of having to make everything by hand? And do you know how you shortened that time? build framework, the way we use 3D printing is within our build parts flow, so if we have something we want to build, let's say this, this sensor holder, I saw it very well, so we'll sketch it out. on how we want to design, so maybe some critical measurements of where some of the sensor dimensions are going to screw in and things like that and then we'll go to the computer and then the computer aid design, I can design it and then 3D print it. out of plastic and sometimes that's a usable part like on that bracket, yeah, but if we're making something maybe like a bracket for a motor or a pulley, um or something like that, we'll 3D print it and then we'll test it.

Fits, I have that look down there, so before you cut metal on a mill, you're going to 3D print it. Screw it in, make sure it clears everything up, yeah, so we can go back, change the model if we have to. with any type of upgrade we can either 3D print it again and retest it or if we are sure it is okay to be machined and fabricated we will send that CAD data and ask someone else to do it or we will do it here. on the face your intake manifold now which, as I understand it, is also 3D printed, but it's not plastic, this is real 3D printed aluminum.

The intake manifold we needed to do because when we switched to port injectors, the injectors in the intake manifold there are no provisions. For this there are no holes in the factory one because we have limited resources, we are spending time

building

the engine and the car, we did not want someone to spend a lot of time on the intake manifold to be able to cultivate it, take it out and print it in 3D, also, the printing 3D was a super cool hack, yeah, and I want to do something different and go through that whole process of how you 3D print metal and then that way in the future when we have more parts that we think could be 3D printed.

We have already gone through that process and can do it efficiently. That is incredible. It's a small car. You know, what's up with drift? Is it easier or more difficult to drift in a short direction? long wheelbase car, can you tell me a little about that? Yes, so the theory is that the wheelbase is shorter, the car will want to change direction faster, a longer wheelbase, it will slow everything down, it may be easier to drive in some ways, we think you can adjust that according the track width of the car because it's actually a ratio of the wheelbase to the width will give you a certain rectangle, you know, the dimensions or the ratio, yeah, but this is a short wheelbase of 97 inches on the hatchback that we used last time.

The year was 106 inches wheelbase, wow that's considerable but so far Freddy has driven the car and really likes it and we're starting to think that the wheelbase is a factor but it's not the determining factor if Is it a good chassis or not. I got it, so why don't we take off some of the wheels and then we can get in there. I'll show you the clever valve suspension that we drove well, perfect what you're talking about when you have a lot of static lean. when you take your wheel and put this whole angle on it, it naturally wants to lift it up and create a flatter contact surface depending on the wheel, you're talking about shock kickback, but this is what I wanted. to see how they're getting that much just continue at that angle yeah within the drift rules of the formula we have to use the factory cross member I have it so this is the factory aluminum supra cross member.

Fab makes custom suspension arms so on the previous cars we like the corolla and things that no one else drifts we had to design and make our own suspension but Wise Fab already had some designs for the suspension on the supra and then RSR builds all of our threaded shocks correctly and you'll notice it too. the big brakes yes stoptech makes these brakes for the supra and this was a bolt on deal and they normally have their hats in black but we decided to anodize them in red because i like red yes i see the red the highlights i I mean this.

Road racing is important, yes, usually, because we are trying to make the cars light, we have gone to much smaller and lighter rotors and calipers, but in this car, because we are on the big rear tire and we need having the car a little heavier, this time we are fine with a larger brake system, these brakes are actually relatively light compared to their size, so we are fine using this cool set of calipers, the front caliper and a of these is traditional. You press the foot brake, it activates the four calipers like a normal car. Some of the drift cars put a little inline handbrake because we want a hydraulic handbrake, it makes it easy to modulate and really easy to lock the rear tires so the driver can do that whenever he wants, when he lines it up with the rear caliper, you can talk a little bit between the handbrake and the footbrake, so if you're on the footbrake and you pull.

The handbrake gets stiff and doesn't respond very well, whether you're on the handbrake or the footbrake, so what we do is we just separate those entire systems. There is a handbrake in the car that has its own master. cylinder that comes out and drives both secondary rear calipers, so they are two separate systems, so it is more comfortable for the driver, it feels better, but we can also use different friction brake pads, drivers will brake a little with the left foot, normally use a fairly low friction foot pad, you don't try to decelerate the rear as much as the front, yes, so you brake very heavily on the foot and then on the handbrake, we want it to be able to block easily, so we use a higher friction pad on the secondary caliper, everything back here is again infinitely adjustable and carries over from the front to the rear and everything goes back to the original subframe.

I see that yes we have to run the factory subframes but we are allowed to mount it solid so we take out the rubber mounts and machine these subframe bushings out of solid aluminum there are no more bushings or anything in the suspension they are all rod ends and Wise Fab makes the suspension for the rear here too and rsr makes the custom coilover. for the back of the car, my goodness, there's not much trunk here anymore, no, yeah, so what we have is the radiator is back here and we have a cooling duct and a fan inside, if you look down.

You can see the winter quick change rear end that we used well and then in the rear here we have the fuel cell, the fuel pumps are inside the cell, we have our nitrous bottle and then that's the fuel bottle. coolant overflow on the side. cooldown overflow and then fire suppression right here, yeah, amazing, and then if you look down you can see one of themotec pdms and some of the wiring, oh I see it right there, yes the way the rules are you can't change them. a lot in the middle of the car, but behind the rearmost suspension point you can do whatever you want, oh I see, so what we do is essentially cut the back of the car and remove all this body work from the factory. and we build our own strong subframe and also a strong crash bar under the bumper, inside the bumper, that way if the car takes a few hits on the track we can repair it or if it's a big hit then we can do all those repairs here in the shop instead of having to go to the body shop and replace large panels.

Let's take a look inside the car. The first thing I noticed is a really nice cage, yes, a very specific cage design, it's an eight point cage and an inch and a half diameter tube. .095 wall thickness, all steel of course, and has to be welded in typically anti-intrusion bars here for the front tires. Oh yeah, I see it, so if the front of the car hits a wall or something big, the tires stay outside the car. not with the driverright compartment The second thing I see right away is I see your Tilton clutch, uh, and your brake pedals with, you know, the masters integrated outside the bracket, so that's pretty cool, there's an actuation pedal per cable for the accelerator and then the brake on the clutch.

The Tilton configuration, the clutch is very typical with a single master cylinder, but the brake uses two master cylinders, one for the rear and one for the front. You can change those sizes depending on what you want your balance to be and there's also what they call a balance bar, okay, there's a line that comes out right in front of the shifter, there's a black knob and you can adjust it by turning it clockwise. counterclockwise or clockwise and will fine-tune the bias from front to back. So driver, you can tweak that during one of your runs and try to get closer to something more like it's off or whatever.

That is incredible. What do you have for a gearbox in this thing? It's a Geforce Gsr transmission. It's a four-speed dog box. instead of using synchronizer, it has dog gear gears and straight cut gears, very strong tons of ratios available to it, still an h pattern, still an h pattern and we have considered going to a sequential, uh, but we didn't think that in I actually would. better net results and this transmission is very simple, easy to put into reverse and uh we've just continued with that nice can I sit in this thing? Yeah, jump, you could sit, it's funny, you can sit in a car and you can feel. like you can cause some damage right away or some cars you get in there and you're like, I don't feel safe or comfortable with this, it's comfortable right away, yeah, the philosophy is you know the car is a tool.

The correct driving position and its ergonomics is your interface with that tool and the more fluid we can make it, we believe the driver will have a better experience and do a better job, that shows how much work is required. To make something so complex simple and clean takes a lot of work. I can appreciate all the time and energy you put into this. Yeah, that's where I really appreciate it. I think very good engineering simplifies things again. a complex problem and it simplifies yes, it's great, I can hear it, yes, start it, it sounds beautiful, nice, can I touch the accelerator a little now?

I definitely need to ride this thing, yeah okay, so that car was really cool. the whole store, everything really impressed the amount of energy that was put into that build for such a short time. I mean, I can kind of relate to taking something that's never been modified or made and putting it together, what if I don't know much? about those things, but I'm looking at it, it's a championship car, you know, yes, built by a championship constructor with a championship driver and also the fact that there is a replacement for this location which is 2jz, which actually made a full b. -58 engine development program with the new chassis with everything else.

I love how you got there, making a thousand horsepower and a thousand reliable horsepower, yeah, and next week we'll have even more batim, more wild builds, more of everything I can do. make another one, am I going to get a text message or are they just going to tell me that where I have to be is like showing up at the designated date and time, okay, we have a rearview mirror on the car even though you can't see behind it because of the rear firewall, why do you have a rear view mirror there? I don't know, just when we built the car, we put it in and then we never take it out for frederick to check himself, it has to look good, make sure it looks good before you go to an interview, yeah, that's awesome, very good.
