779AWHP at 41psi on a partial dyno run - Tim Zimmer - Twicks69
Here's a short vid of my Eclipse on the dyno with the new engine for 2009 running a 7-bolt stroker with aluminum rods and custom pistons on a Borg Warner S400SX 74mm turbo with a 1.1 A/R divided T4 housing.

The dyno pull was cut short at 6400rpm due to maxing out the twin fuel pumps and 1350cc fuel injectors.

More to come next year!

640AWHP at 30psi - Tim Zimmer - twicks69
Tim Zimmer's 1999 Eclipse GSX 7-bolt street-driven 2.3L Stroker and Borg Warner S400SX 74mm turbo setup. Produced 640AWHP on 30psi base tune revving to 8500rpm.


This boost level with lower ignition timing (4-8 degrees only) achieved a best ET of ~10.20's and high MPH of 146mph for 2009 during test/tuning sessions.

More to come for 2010!

Tim Zimmer - September 2009 Import Wars Racing on new setup
Here's some videos from the first track passes with the new turbo/engine setup for 2009 doing some test/tuning passes and competing in Quick 16 class.

Timing was at 4-6 degrees on a very conservative tune to get a feel for the car and make sure everything was functioning properly.

Best ET for the day was a 10.2x, and 143mph traps.

First time to the track since 2007, so I needed to clear out the cobwebs and I need to get better with the driver mod. Only 1.5-second 60's for the day, and several bogs/mis-shifts. Again, Driver Mod.... ROFL

Tim Zimmer - twicks69 - [email protected] - 30psi.
Tim Zimmer - twicks69 - www.tmzperformance.com

1st pass of 2009! Import Wars #6 - September 2009.
1.516 = 60-foot
10.278 = 1/4mi ET
136.19mph = 1/4 mi MPH

30psi on extremely conservative tune with 4-degrees of timing on Q16.

This was a shakedown pass to see how the car felt after being on jackstands for a year. As you can see, it did pretty decent!

Look forward to seeing some 8's out of this car in 2010!

Tim Zimmer - twicks69 - 1999 Mitsubishi Eclipse - 2009 Import Wars #7 In-Car videos!
TMZ Performance - Tim Zimmer
October 2009 Import Wars #7 at GLD (Great Lakes Dragaway, Union Grove, WI)

Five 10-second passes back to back on 30psi on safe tune. Highest MPH of the day was 144mph.

The transmission took a hard mis-shift at the prior race causing shifting issues this time out. Oh well, transmission is refreshed and ready to go for 2010! I will also work out the bogging issue off the launch, as it really hindered the ET's for the day due to poor 60-foots all day long.

www.tmzperformance.com

Back-to-Back 9-Second passes in the 2G; In-Car video!
9.97 @ 152mph and 9.94 @ 151mph in 90+ degree air temps/120-130+ track temps!

Slow launches; oh well! :thumb:
