Barber Motorsports Park II

by on May.26, 2011, under Racing

Another great weekend of testing all the updates on #0031. Everything worked as planned and no major issues other than some minor tuning to the fuel injection program. Some things we discovered that will need improving are the driver cooling and ventilation systems, it gets pretty hot in this car! We will test once more before the Rennsport Reunion  in October to be sure that all is race ready. Check out the pictures from Barber

Old PORSCHE Race cars never retire they just move to a new playground!

by on May.05, 2011, under Uncategorized

In 2007 we purchased a NEW “GT-3 Cup” for the IMSA Challenge series run as a support race with ALMS events. After 3 years of fun and several podium finishes by Lloyd Hawkins, the introduction of PORSCHE’s newest version (MY 2010′) of the gt-3 cup rendered  the 2007 model  no longer competitive. Once the word was out that the Rennsport GT-3 was to be sold we were contacted by Jeff Zwart about the car. Jeff is well known in the porsche world for being the film director of several PORSCHE commercials such as “The Family Tree”. Once a deal was struck we found out that the GT-3 would be modified for “OFF-ROAD USE” and sent to Pikes Peak to contest the famous hill climb event. In conjunction with PMNA and the input of Roland Kusmal the gt-3 was loaned a 3.8 “World challenge Spec.” engine, gearbox ratios were changed for maximum acceleration and a top speed of 125 mph. The suspension ride-height was raised and under body panels installed along with rock guards to protect critical componets. Since i have been the only one to work on the car since new jeff asked if i would like to be the lead mechanic for the event. Nerver having been to Pikes Peak it was something quite different than i was used to. When it was all said and done Jeff broke the “Time-Attack 2WD class record by an amazing 38 seconds set the previous year by Rhys Millen. The most amazing thing was that he finished 6th O.A. in a 3 year old production based normally aspirated 2wd car! Ck out the video i think you will enjoy the sight and sound of an old racer on a new playground!

#031 Gets some modern updates.

by on May.05, 2011, under Racing

We have been working on some modern updates for #031 to bring it into the 21st century. Most importantly to improve drivability and increase performance we have installed a MOTEC M4 Engine mangement system and GARRETT GT ball-bearing turbos. The MOTEC system included (6-individual) TMW throttle bodies, billet fuel rails and 950cc injectors, new crossbar linkage and new fuel lines. With a new set of Reid Washbon Racing headers and Garrett GT3071R turbos from Dura-Bilt we should have a much more responsive engine. The turbos required the most fabrication of all the changes due to the offset of the mounting flanges. New stainless-steel hangers,modified exhaust pipes, smaller oil inlet lines and removal of the “catch-cans” along with modified charge pipes were needed to install the turbo’s. The last item we will add will be O2 bungs in the exhaust pipes to install our wideband Lambda sensors to monitor the fuel mixture for any neccessary adjustments to the program.

“Before” with the kugel-fisher mechanical injection and KKK turbos as origionally supplied by PORSCHE, and “After” with the MOTEC EFI, TMW throttles and Garrett turbos. To the “untrained eye” it looks pretty much the same, but if you look closer you will spot the differences!

#027 Gets some much needed new paint

by on May.05, 2011, under Restoration Projects

 One thing PORSCHE didn’t do was put nice paint jobs even on thier top-of the line racers. They used the “cheap” paint figuring that most racers would get painted every season to accomodate new sponsors and or new ownwers, but what if  the car was only raced  twice in  30 years?  With a galvanized chassis and little to no primer the paint has begun lifting and flaking off  from no adheasion. Well we wanted #027 to look just as good as it did the day it was air-freighted from Weissach to LA  for it’s origional owner Otis Chandler. He ordered it in a special Color called “Vintage Racing Blue” and once in California added his personal touch of striping. So in the coming weeks we will strip down to the bare chassis and prep the metal with modern primer and re-spray with an exact color match!
