A walk around vid with Buddy in the rear window:
August 2000 2 weeks after I painted it, minus the t-tops, window seals, trim, and most of the interior panels.
These photos show the dropped K&N air filter base that I modified to fit the dominator 7 5/16" flange throttle body using 2 seperate bases. The reason I did this is because I wanted a 14" diameter, 1 1/4" drop below the air horn flange for hood clearance, which no one makes due to the fact that the filter element flange @ 14" will not clear the float bowls on the huge holley dominator race carbs. The only other alternative was to go with a 16" dia setup which didn't give the proper look I wanted and there arent any x-stream lids for 16" assemblies. Seeing that I don't have float bowls due to it being an EFI setup, I won't run into that problem. So I just cut out the standard 5 1/8" flange and fabbed in a 7 5/16" flange cut from an 11" diameter dominator base. (sorry about the bad photos)
Here's the Zex perimeter "wet" plate system with hard line that I bent to clear the EFI components. I utilized a fuel pressure saftey switch to disable the solenoids if in the event pressure drops below 6psi. The nitrous system is programed for minimum / maximum rpm engagement, throttle positioning activation, ignition timming retard, air - fuel ratio mapping, and leanout deactivation protection in the EFI systems nitrous configuration table so there's less probability to melt parts. Also a new for 2007 programable nitrous pulse width progressive controller software has been flashed to the ECU. This eliminated the need to have a seperate progressive controller which should help improve off line traction when needed by allowing me to ramp the nitrous in or out from 0% to 100% anywhere in the rpm band over a programable period of time. The fueling side for the nitrous system is a "dedicated" (independent) delivery system, although any supplmentary fueling can be done through the injectors.
The nitrous bottle, with a custom machined carrying handle / mounting bracket supplied by Dyno tune.
The two photo's here are showing the fuel lines exiting the sump that I built and welded to the stock fuel tank. The larger line on the left (-12) is to the inlet side of the filter for the EFI system and feeds the engine with an Aeromotive A1000 pump. The line on the right (-8) was previously used for the engine when I had a carburetor on it and now feeds the nitrous system with an Mallory 140 pump. The fuel tank was internally coated with Por 15 U.S. standard tank sealer .
This is the wiring harness laid out before installation. I used the main and injector harness intended for a L98 / TPI small block (84-92 305-350 Iroc Z, GTA Trans am, Corvette) since I used GM style sensors. This was just to get me connected to the ECM as the module has no denomination to a specific engine, make, model, or size and is calibrated to the individual combination. Accel DFI has main and adapter harnesses to connect to just about any engine, it's all just a matter of what sensors are used and configuring the calibration table. Mixing different model sensors such as a honda throttle position sensor on a ford is no problem! Another example, if you want to use a 4.6 litre ford or twin GM LS1 throttle bodies on a custom built twin turbo 1957 392 chrysler hemi engine not a problem! Instalation was not as scary as it looks, all of the plugs are labeled to connect to the proper components and sensors. So you just have to pick the location where and how you want to mount the ECM, sensors, and components.
For any one just starting out with a EFI conversion or tuning I highly recommend getting as much info as possible before purchasing a system to avoid having difficulties in the installation and tuning proccess. Also weight your options between different systems to make sure you choose the one that best suits your personal needs. Once properly installed and understood you will be able to reap all of the benifits of the system with great success. The photo above is of a book by tuning guru and author Ben Strader that I recommend, and covers most systems giving approximate price, options, and features. Below is a link to his site EFI 101 which is very informative, and the tuning forum pretty much covers all makes of EFI systems where you can post any tech questions and trade information.
