A Day in the Life of T1
Wake up, go fast....
T1 Race Development is proud to announce it's partnership with Pfitzner Performance Gearboxes. Having used PPG gearboxes in many applications, including our race car, we're confident in saying they're the best you can buy. We're happy to become a US Distributor for PPG and provide technical support for the product in the US. http://ppgearbox.com.au/
Since Injector Dynamics showed up claiming high pressure capability for our injectors, it seems like the new buzzword in the injector market. It is now common for suppliers to claim that their injectors run at high pressures.
Some have even gone so far as to one up us! "If the ID2000 will run to 9 bar (130.5 psi) then our 2000 will run up to 10 bar (145 psi)!"
We recently ordered a set of EFI Wizard 2000cc injectors and the paperwork claimed "These injectors have been tried and tested to operate at fuel pressures in excess of 10 bar. On our larger fuel injectors such as the 2000's that translates into over 4000cc/min."
When we got them on the bench one of the first things we found was that with a 14V supply, the injectors stopped opening at about 108 psi. So much for 10 bar! Maybe they meant with a 24V electrical system?
The other thing we noticed almost immediately was that as we increased pressure, the flow decreased. That's right! At 14V supply voltage with a 5 millisecond pulsewidth the flow actually decreased as we increased pressure above about 60 psi.
Seems impossible right? Not really. There is a simple explanation, and as usual a graph to illustrate what's happening.
We've all seen the internet math for injector flow rate right? It says that as we increase the pressure, the increase in flow is equal to square root of the pressure change. So for instance, if we increase the pressure from 3 bar to 4 bar the flow should increase by 15.4% (4 divided by 3 equals 1.333, and the square root of 1.333 is 1.154 for a flow increase of 15.4%)
This rule holds true if the injector is held wide open in the static position, but once we cycle it on and off as we would on a running engine the whole picture changes. As fuel pressure is increased more force is required to open the valve, and so the dead time increases. As a result, the dynamic flow does not increase at the rate that it should.
One of the many tests that we perform here at Injector Dynamics is the pressure sensitivity test. It involves testing the injector dynamically at 3 bar, and then increasing the pressure in small increments and measuring the flow increase.
This type of testing clearly illustrates an injector's ability to deliver fuel at higher pressures, and when the data is plotted graphically it certainly separates the men from the boys.
The best part is that it doesn't require our sophisticated equipment to perform this test.
Do you question our assertions that the EFI Wizard has real issues at high pressures (well, we don't really consider 60psi 'high')? No problem, just install one in your New Age or ASNU flowbench, set the pulsewidth to 5 milliseconds, and let it rip. (These parameters are especially convenient by the way because EFI Wizard's own flow test sheet shows flow data at 5msec. Clearly only at 3 bar though!)
So what does this test show? For starters, it shows that the ID1000 has a weaker magnetic circuit than the ID2000, or the ID725 because it will not handle the higher pressures that the other two are capable of. Those of you familiar with the ID line know that we set an upper limit of 100 psi for the 1000, while we recommend pressures as high as 9 bar (130.5 psi) for the ID2000, and the ID725. The graph makes it clear why doesn't it?
Did anyone really think we were guessing when we set those limits?
It also shows that the magnetic circuit in the EFI Wizard could benefit from a dose of Viagra.
So what would you consider to be the maximum useful pressure for the EFI Wizard 2000?
And more importantly, now that we have clearly illustrated just one of the many untrue claims made about the product, will they continue to market them using the same unproven "me too" specs?
Or do we need to continue pointing out the obvious? Stay tuned...
 EFI-102 a HUGE success in Dallas! For Immediate Release: Jan 10th, 2010 EFI University teamed up with T1 Race Development and Injector Dynamics to put on a terrific class for more than 20 students from literally all over the globe! People came from all over the USA as well as from locations as far as the UK, Jamaica, and the Middle East to learn about the latest in EFI tuning technologies in the EFI-102 "Advanced Tuning Concepts" class. Ben Strader, owner of EFI University had this to say: "The class was great not only because of the incredible amount of previously unavailable information that was delivered, but because for me, it was kind of like a class reunion with so many folks that were around at the very first few EFI classes that were ever taught by EFI University right here in Dallas! You could say that Dallas is the "Birthplace" of EFI University, and it was nice to be home!" The class included topics such as: Using P.I.D. control strategies with Boost Control, Traction Control, Lambda control and more. Also, the course included in-depth racing strategies developed on Tony Palo's world famous, "8-second" front-wheel drive drag-race Acura Integra such as "Boost by Ground Speed", "Rev Limiting by Ground Speed" and mapping the engine by using both MAP and Exhaust Manifold Pressures to aid in quickly changing turbocharger configurations without lot of re-tuning. Tony is considered by many to one of the all-time king's of import drag racing and it was nothing short of amazing to be able to use his personal race car for the demonstrations! Also on hand was Paul Yaw, of Injector Dynamics, to discuss in great detail all aspects related to fuel injector design, and the how's and why's of battery voltage compensations being applied by the ECU. He also spent a lot of time going over newer fuel injector design technologies and theory. Paul's work over the last few years has literally changed the way that modern fuel injectors are controlled, and everyone at the class was delighted to have such an innovator on hand! When asked about what was next for the EFI-102 class, Ben Strader said: "Well, it was such a big step forward in content for the tuning community that we have decided to produce a video of the course and make it available online for tuners anywhere in the world! We have already scheduled the shooting dates for the film, and we will be getting it ready for delivery before summer!" Make no mistake, after almost seven years in the business EFI University is still alive and well and still the innovator in training content and concepts! Look for this and many more video courses to come your way in 2010!
ANOTHER DRAG WORLD RECORD USING PPG!
Congratulations to Chris Miller & Tony Palo on their respective times!
The guys at NRG and T1 Racing have done it again, setting lightning times on the strip in their Hondas. Miller from NRG ran a blistering 8.5 sec @ 173MPH which is a new world record, Palo from T1 a scorching 8.8 sec @ 170MPH. Check out Youtube for the vids. Both use Honda PPG gearsets and all here at PPG would like to congratulate both Tony and Chris on the success acheived in 2009, may it continue in 2010!
Furthermore, we would like to thank all our dealers and customers for the continuing support throughout 2009, and send our best wishes for the New Year and the 2010 racing season!
We have a number of exciting developments planned for early in the New Year, so stay tuned for more..! For more information on Pfitzner Performance Gear Sets,

After many requests from Subaru owners, we came up with a solution for those stuck with a side feed injector and a severely lacking selection of fuel injectors. In the past, it was required to source the Tumble Generator Valves (TGV) from another Subaru application with top feed injectors and swap them and the fuel rails to convert to a top feed injector setup. Not anymore, we've developed a new injector and rail combo that will allow you to fit any of the Injector Dynamics lineup into your side feed TGV's with ease. The T1 rail conversion will cover it all from mild to wild with 725cc/min, 1000cc/min and 2200cc/min injector options (all injectors are high impedance, eliminating the need for injector resistors or peak and hold injector drivers). The rail and mounting spacers are CNC'd aluminum and are black anodized. 8mm stainless steel mounting hardware is included as well. Inlet and outlet threads on the rail are -6 AN female and seal with an oring leaving plenty of flexibility for plumbing options. The rail kit is only sold with Injector Dynamics injectors. Each kit consists of 4 injectors, 4 injector connectors, 2 rails, 4 spacers and 4 SS allen head mounting bolts. MSRP for the kit with ID725's or ID1000's is $649 MSRP for the kit with ID2000's is $1139

If you want to witness two record setting FWD drag cars, you better make sure you are at Palm Beach International Raceway on Saturday, December 5th 2009. For the first time in sport compact drag racing history, Palo and his T1 Race Development Integra will line up against Miller and his NRG Tech Racing Civic. The NSCRA has been working hard in making this dream a reality and it will be seen only at Palm Beach International Raceway at the NSCRA's Season Finale. So make sure you head on over to our final event for the 2009 season to not only witness the world's fastest sport compacts battling it out for the grand prize, but to see two record setting, innovating FWD racers that continue to support the sport to the fullest.
Start of the new year right, with an opportunity to learn from a couple of the best in the business. Dan Portera and Dave Zientara will be at T1 Race Development on Jan the 23rd and 24th to teach a class on Turbochargers and Chassis/Track setup. Some of the topics will include: Performance Turbochargers Suspension and Drivetrain setup There will also be open discussion on all topics at hand. If you want to know, we want you to know. Come to this class ready to learn! The cost of the class is $295. Contact Dan at The Turbo School to sign up. 231-830-5102. The class will fill up fast, so get your seat today before it fills up!
T1 Race Development has teamed up with EFI University to offer an advanced fuel injection class. These days, controlling fuel and ignition duties is only a very small portion of what the computer on a race car is responsible for. Power management is just as important as power production. Boost control and traction control are huge in actually putting your power to use efficiently. Knock control can be a big advantage that will allow you to run your engine safely at it's limits. Clutchless shifting with assistance of computer controlled ignition cut is another way to shave time of your ET's. Learn about all this and more at the EFI102 class. This is a very rare opportunity to learn on a real race car on the dyno. We will be using the T1 race car to demonstrate and teach all these features and how to properly set them up and take advantage of them.

Big congrats to Jeremy Freedman for smashing the FWD record at the TX Mile! Running 198, 204, 205 and 208mph!
The TX Mile is an event that has been gaining a lot of poularity over the past few years. It has brought out a lot of big competitors and a lot of amazing cars. The 'race' is simple, who can go the fastest from a dead stop, in 1 mile. Easy enough, right?
The typical 600-800whp 'supercars' that you will find out there will usually end up in the 190-200mph range.
Jeremy has been at it a few times now, bettering his speed at every showing. Clocking a healthy 171mph the first time he took the VW out there, a lot of people took notice. The next year when he went 193mph, people really started wondering what was going on. This year when we really got things dialed in and the clocks showed 208mph, the specatators were down right confused.
The TX Mile is a unique experience. From the starting line, you get a good view of the first 1/4 mile or so. Past that, you just watch and wait for the board to pop up a top speed. Many of the big power cars really get after it on the first 1/4 that can be seen and you get used to seeing that and 180-190mph speeds pop up. The little VW that could doesn't look too exciting on the first part of the track. Running 700whp through Hoosier high speed road race tires doesn't work so well down low. You should see the faces of the spectators when they watch a nice smooth Motec traction controlled launch and 200+ show up on the other end! WTF?
Jeremy's VW is a 1998 GTI with a 2.8L VR6 engine. A MoTeC M800 ecu controls an M&W Pro 16 CDI ignition and 6 Injector Dynamics ID1000 injectors. Air is provided by a Bullseye Power S366 turbocharger. The combo makes 716whp and 600wtq at 29psi.
