In addition to the recent suspension work accomplished on my car, I also had 
some fuel delivery mods done. While out in California for the ACNA Nationals, 
I did some baseline runs on a chassis dyno to set my air/fuel ratio. My 
wideband air/fuel gauge's O2 sensor was kaput and I wanted to get some accurate 
readings at sea level. During these runs, I noticed that my fuel delivery was 
tapering off at the top end. I backed the boost off to prevent any problems at the 
track. This was only a minor issue here at altitude but I knew I needed to 
provide some additional protection for those high boost runs. Trevor Frank 
suggested going to larger injectors to allow running a lower fuel pressure with 
increased fuel flow capability from the stock fuel pump. 

When I got back to Colorado I had several discussions with Dave Jones about 
how we might go about correcting this issue. Based on his recent findings with 
the 2 European Car magazine competition cars, he suggested increasing the size 
of the fuel lines, adding a fuel reservoir and a high flow fuel pump. So, 
that's what we did. It is just so cool to have this type of expertise available 
next door here in Colorado. Here are 2 pictures of the my new fuel delivery 
system. See anything different?

Brooks, the same guy at Autosport Werks that does the FMICs, welded up the 
fuel reservoir which is the piece that mounts vertically. The other piece that 
mounts horizontally is the Bosch Motorsport high flow fuel pump. Brendan Rudak 
did all of engineering and fabrication work on this installation. In addition 
there are the new fuel lines and when Sportec gets back in town we'll throw on 
the larger injectors and reconfigure the programming to compensate. I 
apologize to Dave Forgied for not having everything polished for this picture but 
Dave Jones wanted everything mounted and leak checked before I did that. I'll 
have those pieces over to my polishing shop next week Dave.

I'd like to say I felt a big difference on my butt dyno with this mod but by 
its nature that's just not the case. I did notice a significant increase in 
boost pressure requiring me to dial things back to get to my street low boost 
setting of 24lbs. Its going to be real interesting to see the dyno numbers once 
Sportec is finished with the software. Thanks again to the gang at Autosport 
Werks for pulling this off.
