It's Alpha Time!

  06/04/13 11:30, by GoodSpeed Performance, Categories: News, Announcements, Dyno, Tuning, Forced Induction

GoodSpeed Performance is no stranger to the Nissan GT-R and the VR38 motor.  Over the years we have had the opportunity to work on several of them.  For most people who own GT-R's, what can be had with bolt on's and tuning is enough.  Every now and then it's not.  When that happens, we look to AMS and their Alpha packages.  GoodSpeed Performance has a long history with AMS Performance and we were thrilled to become an Alpha Dealer, and start offering Alpha 9 installs, in house!

Our client has had his GT-R for some time and finally decided to go big!  His concern was that the car had to be safe and reliable as a daily driver for him and his wife!  With AMS parts and tuning, we knew we could deliver on those needs!  Time for some pictures! 

Here is photo of it's first day at GoodSpeed during the baseline run.  The car made 400.8 AWHP which is right in line with what we normally see out of these cars!

 Engine bay is stock as can be, and dirty (as this is a daily driver)!

 Front end off the car, and the stock intakes and intercooler have got to go!!!

 Here is a picture of most of the major parts about to go on the car!  Lots of hoses, pipes, fittings, etc were left out for better effect!

The package includes:

  • Billet Wheel Upgraded Turbos
  • 90mm Catless Downpipes
  • 90mm Midpipe
  • HKS Legamax Exhaust
  • AMS Wastegate Actuators
  • AMS Alpha Intercooler
  • AMS Alpha Intakes
  • Dual Tial Q BOV's
  • AMS Proprietary Injectors
  • AMS Upgraded Fuel System Including Dual Pumps
  • Cobb AccessPort with ECM and TCM Control
  • AMS Alpha Software Tuning
  • All Neccessary Accessories and Connectors

 In order to swap turbos on a VR38, the engine has to come out, so down she comes!

 Engine is out, this is what we call the point of no return!  It's going to go back in bigger, better and FASTER than it came out!

 Installing the left turbo first and all the accessories that come with it!  The AMS kit is very good in that all neccessary parts are included!  Nothing less than the best at this level!

 Here you can see the stock downpipe on the right compared to the AMS catless pipe on the left!  Huge difference!!!

 Time for the right side to get a matching turbo!  The tolerances with this kit are amazing!  Everything fit perfectly like it should!

 Both turbos are on and the engine is getting buttoned up to be put back in the car!

 Engine is in!  With all that extra boost, you know AMS has the solutions to drop the Intake Air Temps!  HUGE front mount to replace the (still pretty impressive) stock unit!

 Plumbing is installed, intakes are going on!

 Finally, time to tune the Alpha 9 GT-R.  Due to our horrible 91 octane, AMS and GoodSpeed custom tuned the car for about a week.  We made 11 software revisions and did countless logs!  Some tuners would have stopped at 3-4.  With AMS and GoodSpeed, we didn't stop until it was done right.  Startup, idle, part throttle, full throttle, A/F Ratio, etc ALL had to be perfect.

 Back on the dyno, time to see what it can make!  The excitement was definitely in the air this day.  We had people stopping by watching through the window all day!  Our neighbors even came over to see what was running in there!

 A clean engine bay any GT-R owner would be proud of!

 Almost ready for delivery!  As you can imagine our client was excited to pick the car up!

Finally, the proof is in the pudding.  This Alpha 9 GT-R put down 667 AWHP and 668 AWTQ to the MaHa Dyno!  That is on our terrible 91 octane pump gas!  That is a 267 awhp gain over the baseline on PUMP GAS!!!


To say that we were thrilled with the results is the understatement of the year!  We couldn't be happier with the car, AMS products, or AMS service.  They make a great product, have great expertise and worked with us through the entire build to make one client VERY, VERY happy!

If we can assist you with your GT-R whether it's an Alpha or just bolt on's and tuning feel free to contact us at 480-747-6150!

It's official, the hot new car is the Audi TT-RS!  These cars are incredible!  We have had the fortune of having 4 or 5 of them in here recently and a few more for dyno's!  We have compiled a ton of good baseline data!  As good as the cars are stock, more and more mods are becoming available for them seemingly by the day!

So far, we have done tunes, an intercooler, exhaust, methanol injection with a GoodSpeed Performance CUSTOM meth tank, and a few other goodies!  With a tune, exhaust and methanol, these cars make OVER 420hp and 460tq!  The power comes on hard very fast and carries all the way to redline!!


If you have been on the fence about whether or not to tune your TT-RS rest assured these cars are very tune friendly and we can make them the brute monsters they were designed to be!!  Give us a call at 480-747-6150 to discuss options!

TT-RS gets some cool new power in the hot desert!

  06/23/12 11:33, by Jon@GoodSpeed, Categories: Announcements, New Products, Dyno, Tuning, Forced Induction

The Audi TT-RS is an out of the box rocket, but out here in AZ, as I'm sure in many places west of the Mississippi, the fuel is just not what the hotrod TT wants to drink.  We have found that many of these cars are pulling timing due to detionation straight off the show room floor!  So what we did was added a full custom meth injection system to cool the hot intake charge down and boost octane.  Since we had the cooling and the octane needed to make good power; we also gave the inline five a new tune (93oct) to bump up the ponies even more. The results where grand; take a look at the dyno sheet. This was in over 102F ambent temp!!!


Huge gains in horsepower and torque, as well as a smooth power curve that pulls all the way to redline!  Of course this took a bit of tuning of the HFS-4 Meth controller, allowing us to dial in the meth as needed!  The HFS-4 Aquamist system is specifically designed to work with direct injected power plants, utilizing the signal from the ECU to the injectors to calculate load as well as cross referencing the pressure sensor to give the ultimate in precision meth control. Of course we didn't want to just stick another plastic bottle in the rear hatch, taking up more space, as well as putting the the meth just feet from the driver.  So we engineered and fabricated a perfect fit, all inclusive, tank that bolts securely to the core support under the hood.  This tank also acts as the home of the pump, flow sensor, and control valve. Taking into acount that this car is brand new, we also wanted to make a system that is easy to remove for the dealer if nessasary.  Three screws and one quick line disconnect and the entire unit can be set aside.  It doesn't get much easier than that!


It doesn't stop there!  We needed a way to give the pilot a way to moniter the system so we custom mounted the Aquamist guage in the center pod of the AC vent leaving a gap around the unit to allow for cold air flow to unrestricted into the cabin.  Those who live in hotter climates know how important that is!  We even retained the ability to open or close the vent with the guage mounted!  This also gives an optimal vew to the driver.  The results are a 415hp, 463tq monster that pulls like a freight train!



If you have a TTRS that you would like to get more power out of, or, if you would like it to run like it was supposed to, give us a call at 480-747-6150 and we can talk to you about options and pricing that are immediately available!

RennTech...NOT just for Mercedes!

  06/19/12 19:42, by GoodSpeed Performance, Categories: Announcements, Dyno, Tuning

RennTech has a great reputation inside the Mercedes Benz performance community.  The Team at RennTech have literally decades of tuning experience!  What some people don't know is that RennTech tunes many different vehicles!  From Porsche to Bentley, Ferari to Mini, and Maybach to Sprinter, RennTech has something to offer for each!  GoodSpeed Performance has been doing a lot of the non Mercedes flashes lately and the customers and us have been very impressed!

We recently tuned a 996 Turbo S Porsche Cabriolet resulting in 527hp and 549tq at the crank.  Driveability is like stock, just much more power!  Insane horsepower pulling all the way to redline!

We have also had a string of Sprinter vans visit us lately! A quick and simple tune can net the Bluetec vans ~80hp and >100tq! We also found out that they fit on our 4 post lift!  Some of our clients have these as their weekend getaway vehicles and are surprise to hear we tune them!  :)

Rest assured that RennTech's experience and care is present in any vehicle that they tune!  At GoodSpeed you also get the peace of mind knowing that you are dealing with a fully authorized RennTech dealer/tuner!  If you have any of the "other" vehicles that RennTech tunes, don't hesitate to call Jon or Mason at 480-747-6150 to get some more power!! 

A cool 3 Minute ESS Tuning M3 Supercharger install!

  03/15/12 09:21, by GoodSpeed Performance, Categories: Announcements, Dyno, Tuning, Forced Induction

Ok, ok, so it's a 3 minute time lapse video.  A while back, we made a time lapse video to show how easily the ESS Tuning supercharger kits installed on the E9X M3's.  We had a lot of raw footage and planned on putting it into a movie.  After quite a bit of time, we realized that we are way better at making cars go faster than we are at video editing.  That being said, we still think it's a cool video that shows the quality of ESS Tuning kits, and how easily GoodSpeed Performance can transform an M3 into a beast!

We did a stock dyno run on the Maha, installed the kit, then did an after run.

We hope you enjoy!


  • Before were 412hp, 304tq
  • After (with stock cats) 593hp, 395tq.

This install takes less than 1 day!

If you are interested in supercharging or tuning your BMW, contact us at 480-747-6150

Did it do it?  Hell yes!  not only did it make 404.5 hp  (close enough) but it did it on our dyno in 106 degree heat and with our crappy 91 oct Arizona gas.  Good Job APR!!

Dyno Room!

  05/26/10 13:14, by Jon@GoodSpeed, Categories: News, Announcements, Dyno , Tags: arizona dyno testing, dynamometerr in scottsdale, dyno in the scottsdale air park, dyno tuning, phoenix dyno testing, scottsdale dyno, scottsdale dyno tuning

Goodspeed is once again taking it to the next level, we have now started on the construction of our sound proof pressure balanced dyno room.  This will allow us to utilize the two 50,000 CFM fans mounted roof side to draw fresh air through the room and over the vehicle being dynoed. In addition it will aide in accuracy by providing a true-to-speed air flow over the car allowing us to make run after run with out excessive heat soak occurring as well as reducing over all stress on the power train.  The room is also designed with a viewing area so cars can be watched through a dual laminated sound proof safety glass. This will prove useful  for increased safety during  dyno day events as well as day to day viewing. We at Goodspeed feel that providing this level of facility is a conscious act on our part to keep both our employees and our customers safe. Excessive levels of noise and emissions can cause an uncomfortable and unsafe environment in the workplace, as well as a unpleasant experience for the client. we will keep you posted on its completion!
