Our Day at PRI 2018

Yes, there has been a couple of days gap between this and the last post on PRI 2018.   Let’s just blame it on the weather and flight delays, shall we?

Some of the categories of displays are telling in terms of the industry focus these days.  Dynamometers, and in particular, chassis dynos have been in the tuning world for quite some time.  They are essential parts of the modern tuning process which includes ECU mapping and fuel injection technology.

There were quite a few dyno displays at PRI including some well known names as well as some newer ones:

P1090786

P1090794

P1090797P1090799

P1090819

P1090817

P1090826

P1090827

There were several companies that focus on ECU tuning such as ECU Tek.

P1090641

P1100016

Today’s cars have thirty to forty computers, or more determining how to manage all the systems that contribute to our driving experience and key to all this are the multiple sensors that provide the information that feed the decisions programmed into these computers.

P1090613

P1090612

Fuel injection is a huge part of being able to extract maximum horsepower and still maintain drivability be it a street car or a track car.

P1090667

Holley, once known for its carburetors, has their focus on fuel injection and ECU tuning.

Fuel injector technology has gone from batch-fired to controlled pulse rail mounted injectors to direct injection.  Keeping these various types of injectors doing their job properly is not easy. 

P1100021P1100023

P1100022

For spec racers these tools will allow them to find the best flowing fuel injectors out of a batch of stock parts and allow them to check on their health as the season progresses.  For street car owners using the new direct injection technology it is cost-critical to be able to determine which of their injectors might be failing as they can cost well over $1000 each, and it is a budget blower to replace 8-12 at a time. 

Direct injection allows for precise fuel monitoring that results in maximum power and economy, but it comes at a price.  They operate at thousands of pounds of pressure and a faulty injector can wash a cylinder of oil, resulting in ring and cylinder damage.  Not to mention dilution of the crankcase oil.  The same oil that is used to lubricate the mechanical booster fuel pump.

3D printing, also called additive manufacturing is maturing into a technology that will eventually surpass casting, welding, and machining as the primary method of creating automotive parts and systems.  There were several examples of this technology at PRI this year.

P1090589

Much of the caliper assembly above was printed.

P1090590

P1090591

P1090595

The header above was a combination of printing, welding, and machining.

P1090593

The above part was printed.

P1090606

P1090607

P1100072

TRUMPF, a German company, had a live display of its laser 3D manufacturing technology.

P1100075

P1100079

P1100081

Layer, by layer, this machine fused powdered metal into a 3D part.

P1100076

P1090830

P1090832

Perhaps some day you will go to your parts supplier and have them print out your replacement parts.

There were some interesting displays of technology that we already know and love.  What’s not to love about a turbo?

P1100095

Can you ever have enough on your engine?

P1090896

Can they ever be large enough?

P1090897

Or powerful enough?

How about keeping the exhaust on a turbocharged engine from coming loose?

P1100055

P1100057

Stage 8 has a solution for turbo applications as well as exhaust headers.

Speaking of exhaust, now that you need a large diameter exhaust to get the flow you need for that turbo, how do you manage to have enough clearance?

P1090993

This oval tubing could be your solution providing large flow area with plenty of clearance.

With all that power will the demand on your brakes mean that you are overheating them?

P1090883

Above is an example of a coolant-cooled brake caliper.

Let’s not forget the suspension required to get all that power to the tires and provide the best grip possible.

P1100024

P1100026

P1090722

P1090723

P1090726

This year’s PRI was a treat to attend.  If you are part of a race team or support shop you owe it to yourself to spend a few days at next year’s event.  Nowhere else can you see so much relevant products and displays in one place.  I know that I’ll be in Indianapolis next year!

PRI 20018 our second day exploring

As promised today’s entry will focus on some of the interesting product exhibits that we discovered while navigating the crowded aisles of PRI. Attendees were having a great time taking in the thousands of booths and displays. I always get a kick out of “Machinery Row” with all the machines from simple sanding wheels to five-axis milling machines.

While I continued on I came across an old friend, Robert Young, of Forced Performance. Back in the day when I had a 1997 Mitsubishi Eclipse GSX, I was looking for ways to get more out of the turbocharged four banger and Forced Performance had a wonderful upgraded turbo known as the Big T-28. So along with improved cam shafts, and a reworked cylinder head from Road Race Engineering, I installed one of Robert’s Big T-28s. The resulting horsepower provided me with many exciting and successful track days where I was often able to pass Corvette C5 Z06s with my 2 liter 4G63 engine.

It had been a few years and it was nice to meet up with Robert in person. Along with Forced Performance, he and TiAL Sport have partnered to form another business known as Xona Rotor. Robert spent some time with me explaining the engineering breakthroughs that they have been able to bring to their turbos.

One of the latest improvements is the splitter rotor whose design incorporates alternating rotor blades that are stepped down in dimension. This seemingly simple change has brought forth huge benefits in terms of efficiency and power.

clip_image002

It provides faster spool-up with less energy wasted. It is like getting 100 free extra horsepower.

Robert also gave me an education in the internal design of the xona turbos where the shaft seals can not only endure the heat generated, but use the inevitable carbon buildup to form a protective seal of its own.

All the main components of xona turbochargers are made in-house and in the US, which is also a plus. It was great to get to spend some quality time with Robert as well as get an in-depth education on the latest in turbocharger design.

P1100063

Off we went to explore some more corners of the PRI floor show.

P1090696

There are plenty of attendees and that is especially true on the second day.  Many great and respected brands are represented:

P1100051

P1090689

What I’d like to do is give you a peek at some of the other exhibits that are tucked in the corners and might not be quite so well known, but still interesting.

We found an aluminum car trailer that didn’t need ramps:

P1090731

The whole trailer dropped down so you can drive your car right on.  Futura Car Lifts was there from New Zealand.

There was another company from the US that had their own version. 

P1090981

They are No Ramp.  While they started these to accommodate large utility equipment, they soon discovered that track car owners were looking for a similar solution. 

Any of you out there that follow Formula 1 will recognize this company:

P1090763

They had some exotic machines on display.

P1090757

P1090760

Their computer controlled milling machines are amazing.

Speaking of machining billet aluminum there was a display that really caught my eye.  It was the Bullet display:

P1090635

This company has several engine blocks that they make out of aluminum and since I have had several Mitsubishi cars that used the turbocharged version  known as the 4G63 this really got my attention.

P1100010 

P1100013

They are not cheap, but for racing they can cut the engine block weight nearly in half and still support horsepower well over 1000 bhp.

Let’s check out some of the other companies on display.  Here is Jack Tech:

P1100123

They first had a booth at PRI a couple of years ago and offer some of the most innovative shop equipment around.  Their strut spring compressors are fast, safe, and effective.

P1100126

P1100128

P1100130

Shop floors are always in need of a quick cleanup and you never know if it will be oil, antifreeze, or something else.  Well, here is a powdered product that quickly soaks up just about any liquid and makes it easy to sweep up and off your shop floor. 

P1090953

P1090951

How about dealing with tools and parts as you remove and reassemble? 

P1090997

P1090979

Grypmat make it easy to keep track of parts and tools while keeping them close at hand.  They also protect the car’s fenders and bodywork.

How about a lightweight welding helmet that gives you panoramic vision along with auto-darkening and true color representation?

P1100099 

P1100096

They are Jackco Transnational, Inc.

There is even more interesting stuff out there and I will save them for another post.  PRI 2018 is like nothing else!

PRI 2018–The First Day

We flew in to Indianapolis yesterday afternoon and waited excitedly for today’s start of the Performance Racing Industry show in downtown Indy.  As usual there was a long line waiting for the kick-off breakfast.

P1090537

This morning’s guest interviewees were none other than Al Unser and his son who were interviewed by Dave Despain, even though Dave has professed to have retired.

P1090555 

It was a treat to hear these two racing greats recount past glories and entertain us with their memories.  They both have a wonderful sense of humor and they do enjoy themselves.  If you ever get to Albuquerque, New Mexico, be sure to visit their museum there.  With a little luck you will probably get to meet them as well.

When the breakfast and interviews were complete the attendees headed to the show floor and the vast number of exhibitors that populate the show. 

I will get to some of the exhibits that I found most interesting, but first lets take a tour of the many cars that were on display.

P1090573

P1090575

P1090576

There was also a display of a few of the Unser family race cars.

P1090939

P1090940

P1090942

P1090945

There was also a display of a very unusual Indy racer that was once driven by Joe Leonard.

P1090703

P1090705

P1090706

P1090708

P1090711

At the time it was revolutionary with its dihedral wings and its highly turbocharged Offenhauser four cylinder engine.  The Offy engine had the head integrated with the block so there was no head gasket and consequently they could really increase the boost pressure.

Here are several other cars that I saw as I perused the aisles.

P1090614

P1090615

P1090754

P1090839

P1090848

P1090849

P1090854

P1090857

P1090859

P1090888

P1090890

P1090908

P1090910

P1090911

P1090917

P1090932

P1090934

No, PRI is not a car show, but it certainly has some interesting competition vehicles to view.

Tomorrow I will focus on some of the exhibits of the various vendors that I found interesting.  Stay tuned.

Things You Find on the Side of the Road

On our travels back east we came across this sight at a gas stop.

P1080664

These are some great old trucks that they use out front as a display.

P1080666

P1080668

This old Mack truck is being towed by a White truck.

P1080673

P1080670

There was an even older yellow truck.  Can you guess what brand of truck it is?

P1080676

P1080680

P1080681

P1080679

It is a Mack truck as well!

Strange Things on the Side of the Road–Clarence Kansas

If you didn’t know that it was there you would probably drive right by it, but in the small town of Clarence is the most unusual gas station I have ever visited.  It is on an intersection and in back of it is a large grave yard.

P1070315

The cars are mostly Fords and are occupied by several realistic mannequins.

P1070316

P1070321

P1070328

P1070325

P1070330

P1070339

P1070333

P1070336

P1070343

I don’t think it can be called a museum.  Maybe its just a place frozen in time.  Or it could be… the Twilight Zone.  See for yourself.

Things on the side of the road–Delta, CO

Just driving around and as I am heading to a tourist attraction we pass this place:

P1080104

With a squeal of the brakes and a quick u-turn we stop and photograph some real classics.  Certainly these are not restored classics, but man, they are still amazing to look at.

P1080141

P1080136

P1080144

P1080114

P1080128

P1080118

P1080116

Most of these were just across the street.  Here is a shot of the other side of the street.

Hanger 18–a gem on the side of the road

As I travel around I like to stop at car museums, cars and coffee events, and once in a while I come across an interesting car on the side of the road.  This shop really caught my eye. 

P1070903

The colors certainly caught my attention along with a great looking car from the pre-war era.

P1070899

P1070902

Originally this was a Sinclair gas station that has been around Colorado Springs for decades.  In the past year it has been transformed into a great service station.

P1070909

The customer greeting area is colorful and inviting with plenty of certifications on display.

P1070912

P1070914

P1070913

It was an impressive shop with a great staff that was completely focused on providing great service.
