We have just returned from Sydney, Australia for the World Time Attack Challenge 2013 race event and are catching up on unfinished business.  TMZ Performance was assisting Andrew Brilliant with his 2G FWD Eclipse race car in Pro Class for its first race efforts in the international Time Attack arena.  The AMB Aero / GT Auto Garage / Auger Torque / PAR / Competition Clutch sponsored Eclipse had a good test session with a lot of data obtained and driver feedback to move the car to the next level for 2014 World Time Attack race.  We had our fair share of problems with various items on the car, only to find that the coilovers were damaged from the international shipment of the vehicle.  Unfortunately, we were able to only get in one low-boost hot lap @ 1:40.3350 before further issues grounded the car.  Our car was still the fastest FWD Pro Class car competing in the event.  The fastest overall FWD car competing in the event was Benny Tran's BYP Racing Acura Integra in Open Class with a 16th Overall finish at 1:32.6800.  Our goal is sub 1:30's for 2014 in FWD. 

The competition was world class, and track records were broken yet again this year! 

Congratulations to the Tilton Interiors Mitsubishi Evo in Pro Class with its track record 1:24.8550!  This smashed the Nemo Racing Mitsubishi Evo track record from 2012 which was the ground breaking year for full-fledged aerodynamics packages being implemented.  Andrew Brilliant of AMB Aero had several cars with his aerodynamic packages in top competition, including the 2012 champ Nemo Racing Mitsubishi Evo (3rd Overall; 1:27.7080 in 2013; and 1st Overall
1:25.0200 in 2012), Under Suzuki's Scorch Racing S15 Silvia (4th Overall; 1:27.9580 in 2013; and 4th Overall 1:28.329 in 2012) were the two standouts!

This was a major opportunity that I could not have had without the support of my DSM community, my friends and my family! Thank you to everyone that has made this happen, and THANK YOU for your generous donations to make this happen for Andrew Brilliant and his race team!

Recommended Vendor Performance parts:

The key part from Beyond Redline Performance that I recommend for DSM, GVR4, and Evo 1-3 owners is their Custom Hardened Chromoly Cross-Shaft to use in the 4-spider center differential upgrade.  It is by far the strongest cross-shaft on the market for these vehicle applications and provides owners with complete streetability on high-horsepower AWD applications.  Instead of machining down the stock cross-shaft to accept 4 spider gears, this part started from scratch with better material, a beefier structure, surface hardening, and oil passage grooves on its posts to provide proper oiling to the spider gears to prevent surface galling.  The Beyond Redline Performance cross-shaft has been proven to hold over 1000HP and 950TQ at the crank on my race car for the last 6 years without signs of galling or damage.  It has been proven on the race track, the street, and the dyno to survive the harshest conditions without failure.

The key parts from Frontline Fabrication that I recommend for modified 1990-1999 Mitsubishi Eclipse/Eagle Talon/Plymouth Laser (DSM 1G/2G AWD) and the Evo 1-3 and Evo 4-9 platforms is the custom Billet Aluminum Custom Rear Differential Cover with Load Caps. It is easily the strongest rear diff cover on the market today and is what holds together the backends of some of the fastest DSM's running preventing rear differential housing failure.  This is what I run on my race car in place of the "like glass" OEM cast aluminum part that is fail prone when you start making real power and want to go fast.  Frontline Fabrication also makes Billet Aluminum Custom Transfer Case Braces for the 5-speed and automatic DSM transfer cases.  The brace fits on all 1991-1999 transfer cases and there are two different designs (one for manual; one for automatic).  Frontline Fabrication also makes Front and Rear Bolt-In Driveshaft Loops for the 1G and 2G AWD DSM platform!  These parts are meeting NHRA specifications and are absolutely perfect fitment and finish!  They are beefy and will protect you from your driveshaft if it fails!  Frontline Fabrication also makes a Custom 2G RACE Bolt-In Fuel Cell for the 2G DSM!  This product has excellent fitment, material finish and overall build quality and is built custom spec to your order for usage with gasoline, methanol, Alcohol or blends such as E85 or E98.

The key parts from Performance Autowerks (PWerks) that I recommend for stock to heavily modified Dodge Neon SRT's start with their Billet Steel Shift Selector (a recommended upgrade for all power levels), their Billet Steel 3rd/4th Shift Fork for heavy shifters (a great upgrade for modified SRT's that are getting a performance rebuild), and the PWerks Billet Steel Input Shaft (this is pretty much a mandatory upgrade for cars making over 400-600whp+ as the stock shaft likes to snap in half without surface treatments). 

We currently offer cryotreatment and shot-peening services for gearsets.  These services work best when they are done on NEW parts after being deburred and detailed. 

*Cryotreatment  is a surface treatment used to refine the microstructure of the item. The cryotreatment process has been proven to increase durability and wear resistance in many applications including transmission gearsets, clutch assemblies, engine rotating assemblies, brake rotors and brake pads, etc.  Once the cryotreatment process is completed the parts are carbonized and heat-treated to strengthen the material.  The cryotreatment services are being provided through The Cryogenic Edge and 300 Below.

is a surface treatment that peens the metal surface with special steel shot to provide an overlapping surface layer of compressive-stressed material.  This compressive-stressed surface material leaves a micro-dimpled surface on gears and shafts to provide increased surface area as well as better surface oiling retention.  Shot-peened gears generally act like they are 20%-25% larger in cross section, resulting in higher torque capacity of a gear.

I currently own one DSM -- I have sold off all the others along the way.

The "race" car is a 1999 Minden Pearl Silver Mitsubishi Exlipse GSX that is very heavily modified, and is one of the quickest/fastest 2nd Gen (1995-1999) STREET DSM's in the country. It is also one of the highest-horsepower and highest-torque 7-bolt 4G63's in the country with currently 1004 AWHP/720TQ (power at all 4 wheels) on a DynoJet AWD dyno at 48psi with the current engine/turbo setup. The pump gas tune made 714 AWHP/530TQ at 29psi.  Dyno numbers are from August 2013.  Due to work schedule, there were no real chances to hit the track for faster ET's. 

As of 2012 Season, the car weighs in around 3280# with driver and has done best backed-up ET's of 9.49 @ 148mph on only 35psi of boost with very gentle 60-foots in the 1.5-second range testing the current setup for suspension dial-in and 2-step dial-in as I am trying out a very tall 1st gear assembly (2.571 Ratio).  Best 1/8th MPH to date has been 132mph on 45psi on a partial run.  The car does consistent 1.40-1.50 second 60's with gentle launches.

The current engine/turbocharger setup has been run from 2009- 2013 seasons with consistent 9.9-10.0's @ 145-148mph on 30psi on 93-octane.  The car is now on Race Components Inc (AFI) 2200cc high-impedence primary fuel injectors and 1000cc high-impedence secondary fuel injectors and running on E85 or E85/C16 mix.
